Description

DETAILED DESCRIPTION OF THE INVENTION The present invention combines plates having a plurality of types of required notches with an appropriate thickness, and rotors are arranged centripetally in the spaces formed by the notches, and A laminated layer in which each of the rotors is placed in these spaces and is in contact with a rail inserted into the center surrounded by the rotors, and the head of the rail is held so that it can easily slide. This invention relates to an improvement of a slide block whose main body is composed of a plate.

Mechanical elements used in relatively small equipment such as doors, shelves, drawers, etc. that move in sliding or reciprocating motion, mainly in linear motion, are generally rotating bodies such as door wheels, or mechanical elements made of lubricating synthetic resin. Although sliders are used,
As is well known, the frictional resistance is high, so the movement is not smooth, and of course the accuracy is low, so it is used in extremely general applications, but it is mainly used for reciprocating elements with high precision and sliding. It goes without saying that the less resistance there is, the more widely used it will be.

In particular, this sliding element may be used in places or applications where it is not necessary to supply lubricating oil or other anti-friction agents, or where the use of oil or fats must be avoided, or where lubricating oil cannot be supplied. It is more effective to use

We first developed a sliding block suitable for this purpose and obtained a low-cost, high-precision sliding block, but due to its structure, excessive external forces act locally on the laminated plate pieces during machining. There are problems such as points that occur and require correction.

Therefore, in the present invention, such problems are solved, and the number of parts is increased, but the laminated plate pieces are unified and easy to work, and it is rationally combined based on the holes of the laminated fastening parts. The purpose of the present invention is to provide a slide block that can achieve high precision and smooth operation.

In the present invention, a plurality of rectangular notches are equally distributed radially from the center, which serves as the center guide hole during silk binding, and furthermore, an incision of an appropriate width is formed from the center ψ guide hole to the outer end. The two types of boards made with the above-mentioned materials are made into left-right symmetrical pieces with reference to the center line extending from the center guide hole to the incision, and a plurality of straws are combined in the required order and placed on both outer surfaces of the pieces. A main body is formed by fastening the outer plate having a central guide hole and a cutout at a plurality of locations through fastening holes commonly drilled in each of the parts and the outer plate using fastening bodies; In each of the spaces formed radially from the center by the notches of the respective parts inside the main body, each rotor is freely supported in a bearing piece provided in a rectangular recess formed by the central laminated plate part forming the main body. One or more rotor bodies are disposed while being supported by a support shaft, and each of the rotors abuts and holds a guide portion of a guide rail in the guide hole of the main body, and the cutout portion is arranged so that the rotor body abuts and holds the guide portion of the guide rail. It is configured to correspond to the passage portion of the web portion of the rail.

In the present invention, the sound of laminating and installing the rotor inside! The outer shape of the laminate plate pieces that make up the parts is unified to the required shape,
By making it symmetrical, the shape is simplified and workability is improved, and the fastening holes drilled in the part are provided in the same position, and the fastening holes drilled in the outer panel are used as a reference. By fastening them together, the main body was made of laminated plates.

Further, in the present invention, the outer plate is provided with the guide hole and the cutout of the guide rail, and the laminated plate part fastening hole provided with reference to the axis of the guide hole, so that at least one of the parts is attached to the laminated plate part. The outer shape is more like a dog, and the part protruding from the laminated part is configured to serve as a seat.

Alternatively, a rotor in which the required guide holes, cutouts, and fastening holes are provided in two or more locations at the required intervals in the outer plate, and each location is assembled into the required laminate plate piece and its internal space. By arranging and fastening them at each position, a composite slide block can be constructed.

The outer shape of the slide block can be rectangular, circular, or any other shape as needed.If it is circular, it can be used as a fastening hole adjacent to the incision. It is sufficient to use a hole that is smaller than the other fastening holes so that it can be inserted without any problem.

The rotor used in this invention can be a synthetic resin roller, a metal roller, a small rolling bearing, or a combination of these. The bearing is rotatably supported by a bearing formed in the space, and oil-free lubrication can be achieved by selecting the bearing forming member.

In addition, as a guide rail, a guide part with a rectangular cross section whose surface that contacts the rotor is flat, and a web part and a mounting seat integrally formed with this guide part, or a guide part with a circular cross section, etc. are used. , mounting seats, etc., are all approximately the same.

Hereinafter, the present invention will be described in detail with reference to the drawings regarding one embodiment.
The one shown in FIGS. 1 to 3 is one typical example, and is a harpoon with a rectangular outer shape], and this slide block A has an appropriate thickness between the left and right outer plates 1.1. A plurality of laminated plates 2 and 3 with two types of notches formed therein are combined and fastened together with a plurality of hollow studs 4 to form a main body 10, with a guide hole 12 in the center and one side. It has an incision 13 formed so that the outer side expands to an appropriate width, and a cutout space 11 is formed inside the central guide hole 12, and the rotor 5 is inserted radially from the center. They are equally spaced so that their rotating surfaces are located, and the support shaft 6 is held in the recess through the bearing piece 7 so that the rotor 5 can rotate freely.

Therefore, each plate constituting the main body 10 can be made of a metal plate or a synthetic resin plate, and the plurality of laminated plates are of two types, and the one shown in FIG. A hexagonal central guide hole 12 is provided, and an incision 13 of an appropriate width is cut out from one side to the outer edge.The outer edge of this incision 13 is formed in the shape of a light spread, and the center passing through the incision Two fastening holes 8 are drilled symmetrically with respect to line a at an appropriate pitch P.

FIG. 5 shows a laminate piece 21 forming the central laminate 2.
When this is arranged symmetrically as shown by the chain line, the central guide hole 12, the cutout 13, and the fastening hole 8 are all provided to be equal to the outer plate 1, and are connected to the central guide hole. A rectangular long notch 22 of a required length with an appropriate width W is formed radially from the center at a position opposite to the incision 13 and on both sides 4 of the incision 13, and with respect to the rectangular long notch 22. The square notches 23 with tips are formed symmetrically in the orthogonal directions passing through the points of the required dimensions from the center, respectively, and the shape is such that cross-shaped notches are formed radially in three directions from the central guide hole 12. In this state, the shape is divided into left and right halves by a center line a passing from the center of the central guide hole 12 to the center of the incision.

In addition, each cross-shaped notch 24.24 sideways square notch 2
The width of 3 is an integral multiple of the thickness of the laminated piece 21.

What is shown in FIG. 6 is a laminated piece 31 forming a space-forming laminated plate 3, and when it is arranged symmetrically as shown by the chain line, the central guide hole 12, the cutout 13, and the fastening hole 8 are all aligned. Rectangular long notches provided so as to be equal to the outer plate 1 and connected to the central guide hole and formed radially from the center at positions opposite to the cutout 13 and on both sides of the cutout 13, divided into three equal parts. The dimensions of 32 are also the same as those of the intermediate laminate section 31.

It is preferable that the outer panel 1, the central laminate 2, and the space-forming laminate 3 have the same thickness.

Next, when assembling each of the laminated plates, the pieces 21 forming the central laminated plate 2 are arranged symmetrically, three pieces at a time, and the pieces 31 forming the space forming laminated plate 3 are placed on both sides. Align the fastening holes of each laminate plate with the fastening holes 8 provided in the outer panel 1 as a reference, and of course, insert the can incisions 1.
3 and each square long notch 22, 32 are also aligned and stacked,
Hollow rivets 4 are inserted into each of the fastening holes 8 to form one piece, and in this way, a longitudinal space 11 is formed by the rectangular long notches 22 and 32 in three directions from the center guide hole 12, and the center In the part, rectangular recesses 14 which are orthogonal to each other by laterally symmetrical rectangular notches 23, 23 are formed symmetrically by the two central laminate layers.

These rectangular depressions 14, 14 are configured so that the cross section passing through them and perpendicular to the axial direction is square, and a square bearing piece 7 is fitted into this rectangular depression 14.
Both ends of the support shaft 6 of the rotor 5 are accurately and rotatably supported, and the rotor 5 is installed inside the space 11, respectively.

The rotor 5 is made of synthetic resin or a small rolling bearing.

The slide block A constructed as described above has a guide head 41 having a hexagonal cross section as shown in FIG. The installation is achieved by slidingly fitting the guide rail 40 forming the seat 43 so that the rotor 5 contacts the top surface of the guide head 41 and the slopes on both sides of the legs 42, as shown in the figure. 40, the target support guide can be moved freely and easily via the slide block A.

In order to attach the slide block to a movable object such as a sliding door or a movable table, a recess into which the main body 10 can be fitted is formed in the slide block, and the main body 10 is mounted as shown in FIG. Tighten the port 16 such as a wood screw using the inside of the fastening hollow rivet 4,
Guide head 4 of guide rail 40 installed in advance
1 is fitted into the central guide hole 12 through the cutout 13 as described above, and each rotor 5 is brought into contact with the guide head 41 so as to hold it (this contact-related dimension is determined in advance by the guide rail. The dimensions of the guide section are set to match the dimensions of the slide block for contact with the circumferential surface of the rotor), allowing smooth and accurate movement along the guide rail 40 without floating or coming off. It is possible.

At this time, the rotor 5 support shaft 6 disposed in the space 11 in the main body 10 is supported by the bearing piece 7 inside the rectangular recess 14 formed by the laminated plates as described above. Accuracy is required even though the main body is formed by laminating layers.

As described above, the slide block of the present invention slides while holding the so-called head of the guide rail by the built-in rotor, and is moved by the rotation of the rotor.
By ensuring precise contact between each rotor and the guide head, highly accurate movement operations are possible.In particular, the rotor is made of synthetic resin, and the bearing piece is made of oil-impregnated sintered metal. It is suitable for use as a moving element for equipment and equipment to avoid the generation of vibration and noise, and as a moving element in places where the use of oil and fat is avoided, and can be very effective. It is.

In addition, when manufacturing it, as mentioned above, it is necessary to form a polygonal notch part that forms the inner thigh part of the rotor other than the outer plate, especially at a position opposite to the cutout part. When press-cutting an integral plate, a narrow part connects comparatively wide areas on both sides, resulting in distortion, which requires a lot of effort to correct. By dividing the pieces into left-right symmetrical pieces along a line, the parts that were prone to distortion were cut away, eliminating the distortion caused by punching. By making a set of sheets, it becomes the required shape of one intermediate laminate plate during assembly, and when assembling, there are two fastening holes each on the left and right sides of the outer plate, and each fastening hole on each laminate part. By matching the parts and fastening them with rivets, it was possible to reliably integrate the parts, and even though the number of parts was large, a reliable product could be obtained without the need for any correction machining, which in turn reduced production costs. .

In this way, in the present invention, when configuring the main body by laminating layers, by assembling them based on the fastening holes, it is possible to easily achieve the desired configuration even if the internal shape of the laminate plate located in the middle is complex. This gave them the advantage of being able to be formed in one piece.

It goes without saying that according to the spirit of the present invention, the same effect can be obtained even if the outer shape of the slide block main body is circular.

Furthermore, due to the structure of the slide block installation, the shape of the outer panel can be changed according to the requirements. To give a specific example, the one shown in Figure 9 has outer panels t', i'
The side opposite to the cutout 13 is bent outward to form this part as the mounting seat 17, or in the case of the one shown in Figure 10, the side of the outer panel 1", 1" on the cutout side is bent outward. This part is bent to form a mounting seat 17', and the former (shown in Figure 9) is used when mounting the object protruding from the bottom surface, or when the guide rail is arranged vertically or horizontally. The latter (shown in Figure 10) is suitable for use when the main body is fitted into a recess cut into a moving object and is mounted in a low-volume state.

In addition, as shown in FIG. 11, only one of the outer plates 1a is made to protrude from the other laminated plate part in the left and right directions with respect to the cutout 13, that is, the guide rail, and this protruding part is installed as a seat 11'. Alternatively, the outer skin can be extended to the side opposite the incision and used as a mounting seat.

Furthermore, in addition to the single-piece type explained above, the above-mentioned pieces for forming the intermediate part in a laminated manner are used, and the outer plate is made of a single piece as shown in Figs. 12 and 13, for example. It is also possible to form a so-called double-row type slide block B in which a plurality of guide holes 12' and cutouts 13 are provided in the plate, and each guide hole is integrated. And the direction of the incision is not limited to the above example,
It can be set in any direction depending on the purpose of use and the situation, and even in this case, it can be easily configured by assembling the fastening hole as a reference.

In the case of such a double-row type, when moving in a cantilevered manner, or when guiding an object in parallel,
This is effective when a relatively heavy dog is guided in a straight line by a small guide mechanism.

Further, in both the single type and the double row type, the cross section of the guide portion of the guide rail may have a shape other than a hexagon, and the same effect can be obtained even if it is circular or occluded.

Furthermore, when arranging the rotors in the main body, in addition to arranging them in pairs as described above, by arranging and stacking multiple central laminated plates at an appropriate pitch, the rotors can be arranged in double rows in the axial direction of the guide rail. It can be made into a small slide block that can handle large loads.

Next, in accordance with the spirit of the present invention, the two types of laminates for center and space formation are divided into left and right parts from the center and are combined, so as shown in FIGS. 14 and 15. As shown in FIG.
The dimension from the center to the edge 19 on the opposite side is made longer than in the previous embodiment, and the side opposite to the cutout 13 of the piece 21 constituting the central laminate 2 excluding the outer panel 1. The shape is such that the part forming the long angular notch 11 penetrates the outer end during assembly (the other parts are the same as in the previous embodiment), and the piece 31 constituting the space forming laminate 3 is also opposite to the cutout part 13. The free-length notches 32 on the sides are cut out longer than the free-length notches in other parts, and when assembled, the support rod 45 whose base end is formed into a T-shape is connected to the central laminate plate 2 with its upright part. The rod 45 protrudes from the center of the end side 19 of the section, and is fixed so that the proximal sideward protrusions 45', 45' exactly fit into the space forming portions of both space forming laminates 11, so that the rod 45 protrudes an appropriate length; By providing a threaded portion at the tip of this support rod, etc., the slide block A' is attached to the movable body by the support rod 45 and is configured to be rotatable at a position orthogonal to the guide rail. can be taken as a thing.

With this shape, for example, it can be used as a movable hanging guide block for an accordion-type partition wall, or for an object to be guided and moved along a guide rail, and the object can be rotatably attached via this slide block. You can reasonably obtain what you can.

Of course, if this support rod is used, various methods of attachment to other objects can be attempted, and its uses can be further expanded.

Therefore, it goes without saying that the configuration is not limited to the above-mentioned specific example, but can be changed to any shape as required.
