Description

[Detailed Description of the Invention] The present invention relates to a slide bearing device in which a plurality of bearing portions are formed in parallel in a frame portion of equipment etc. using laminated plates, and can be used by rationally incorporating a movable shaft. .

When moving multiple axes in the axial direction of relatively small equipment all at once or at different times, conventionally the support bearings for each axle were individually attached to the required locations on the frame. Each shaft is supported by a bearing, and therefore the construction involves drilling a bearing mounting hole in the frame and fitting a separate bearing into this mounting hole. Although it may seem easy at first glance, the installation accuracy tends to be low, and if you try to assemble it with high accuracy, it will take more time and especially skilled techniques, which will increase the labor cost. If the mounting distance is narrow, many structural problems arise, such as the need for irregular mounting means or a specially shaped bearing holder.

The present invention solves this problem by directly forming a bearing part for supporting a plurality of movable axes in the required arrangement in parallel on the frame or support plate of the equipment, and manufacturing it rationally and precisely. The object of the present invention is to provide a bearing device that can be easily used.

That is, the present invention provides a device in which a frame or similar support of a required device is integrally formed by laminating a plurality of metal plates, and slide bearings are installed at a plurality of required positions of the frame, and includes:
The constituent metal plates include an intermediate plate in which a plurality of rectangular notches are equally cut out and arranged radially from the axis of the central guide hole at each sliding bearing forming position; and square notches are equal to each other, and rectangular notches are symmetrically formed on both sides of the long square notch so as to be orthogonal to the long square notch at a required radial position from the axis position. a central plate having a cutout;
It consists of at least three types of plates: an outer plate with a central guide hole bored at a predetermined position; and a plurality of intermediate plates before and after the central plate, and an outer plate on the outside of each intermediate plate. All of these laminated plates are fastened together with fastening bodies at positions separated by an appropriate distance with respect to the axis of the central guide hole of each bearing forming part, and the notches of these laminated plates are In each space formed radially from the central guide hole, the rotor is supported by bearing pieces fitted into square recesses in the cross-shaped notch of the central plate, and the rotor is inserted through the central guide hole. It is constructed so that it can move freely in the axial direction, supporting a shaft or something similar.

With this configuration, slide bearings can be manufactured by incorporating them into the frame or support of the target equipment, or parts for multiple operations, at preset positions. Since the housing of the bearing will be formed by stamping all of its main parts, the laminated plates should be assembled in the correct order and the space formed by each plate should be filled with bearing pieces and free space. By fitting and assembling the rotor into the fitting shaft pin, it is easy to manufacture even a device with multiple bearing parts, and by matching the set number and position of the bearings to the plate, it can be mass produced. It has become possible to easily manufacture an integrated multi-bearing built-in support with improved dimensional accuracy and a low bulk, and it has become possible to obtain a panel-type bearing device with a rational, reasonable and effective laminated structure. .

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. What is shown in FIGS. 1 to 4 is a specific example, in which slide bearings 10 are arranged at four locations on a frame 1 constituting a device. A plurality of plates 3 and 4 having two types of punched holes are combined between the outer panels 2 and 2 and have an appropriate thickness and the same outer shape as the outer panels, and are integrated by a large number of hollow rivets 5 at required positions. It is laminated and fastened to
Each of the slide bearings 10 provided at three locations has the same structure, and is attached to a central plate 3 interposed between the outer panels 2 and 2, and an intermediate plate 4 interposed between both sides of the center plate 3 and the outer panels. A plurality of elongated spaces are formed by dividing the central guide hole 11 into equal parts radially from the center, and the rotor 17 is placed in each of the spaces 15, and the rotor 17 is rotated about the center guide hole 11. The rotor 17 is equally distributed so that the surfaces thereof are aligned in the centripetal direction, and both ends of the support shaft 18 are held via bearing pieces 16 in recesses formed on both sides perpendicular to the space 15 so that the rotor 17 can rotate freely. The frame 1 is connected and fixed by stays 6 at appropriate intervals.

Each plate constituting the frame 1 in which the bearing portion is integrally formed is preferably made of a metal plate,
The outer plate 2 has the stay 6 mounting holes, shaft insertion holes for each bearing (corresponding to the central guide hole 11 in the slide bearing 10), rivet holes for fastening in the vicinity, and other parts mounting holes as required. It shall be determined by the allocation. Among the plurality of plates disposed between the 22 outer plates, the central plate 3 has the same external shape and hole arrangement as the outer plate, and the positions of the slide bearings are as shown in FIG. As shown, the central guide hole 11'
is provided with a required diameter, and a rectangular long notch 12 of a required length is formed radially from the center at a position divided into three equal parts, with an appropriate width (W), and for each of the rectangular long notches 12, Square notches 12'', 12'' with stepped tips are formed symmetrically in the orthogonal direction passing through a point of the required dimension from the center of the central guide hole 11', and 12'' are formed radially in three directions from the central guide hole 11'. Glyph cutout 13
is formed. The intermediate plate 4 has the same external shape and hole arrangement as those of the outer plate and the center plate, and the center guide hole 11'' is the same as that of the plate 3 at the position where the slide bearing is formed, as shown in FIG. Similarly, the rectangular notches 12', which are divided into three equal parts from the central guide hole 11'' and connected radially, are made equal to those of the central plate 3. It is preferable to use plates having the same thickness.

The slide bearing 10 formed by the plates 3, 4 and the outer plates 2, 2 has three central plates 3 in the center, two intermediate plates 4 each on the front and rear thereof, and the outer plates 2, 2. 2, it is clamped from both sides, and each square notch 12, 12' connected to the central guide hole 11', 11'' is aligned with the fixing hole uniformly provided near the central guide hole 11', 11''. If the rivet 5 is inserted and fastened, the center guide hole 11 to 3
A longitudinal space 15 is formed by rectangular long notches 12, 12' in the direction, and a rectangular shape is formed by laterally symmetrical rectangular notches 12'', 12'' orthogonal to the rectangular long notches by the laminated portion of the central plate 3 in the central part. Recesses 15' are formed, and bearing pieces 16 are fitted into these rectangular recesses 15', and the rotor 17 is freely supported on the support shaft pin 18 whose both ends are supported by the bearing pieces 16. and is installed rotatably within the space 15. The rotor 17 is preferably made of synthetic resin, sintered metal, or a small rolling bearing, and the bearing pieces 16 are preferably made of oil-impregnated sintered metal.

Necessary parts are assembled between the frames 1 and 1 having the slide bearings 10 thus constructed according to the various structures of the equipment, and each slide bearing 10 has the parts shown in FIGS. 3 and 4. A shaft S is inserted to be supported and in contact with each rotor 17 of the bearing 10, and necessary parts or instruments are mounted on this shaft S. Then, power is applied to this shaft S from other parts so that a propulsive force in the axial direction is applied, so that it reciprocates over a required distance between the frames 1, 1, and in this case, one shaft or multiple shafts can be In any case, if a moving device or part is attached and reciprocates in the axial direction, the shaft S is located in the space 15 of the bearing 10 part.
Smooth movement is achieved by rolling support by the rotor 17 provided inside the shaft.In particular, by making the outer shape of the shaft S polygonal (hexagonal in the embodiment), the shaft S and the rotor 17 can be easily moved. are supported by line contact, allowing easy and reliable operation even under heavy loads. Further, even when a plurality of shafts perform different operations individually or in combination, the movement in the axial direction is performed smoothly in the same manner as described above at the support portion of each shaft.

In addition, one or more sets of 10 slide bearings are arranged at the required positions on the frame 1, 1 side, and the slide bearing is installed on the equipment fixed on the shaft S arranged on the slide bearing section, and both ends are fixed on the frame side. By fitting the slide bearing on the equipment side into the guide rod, lateral movement can be performed extremely smoothly. In the slide bearing part, the bearing piece 16 is made of an oil-impregnated alloy and can be operated without lubrication, so there is no possibility of oil or fat adhering to the shaft or leaking to the outside, and therefore it is used in areas where contamination due to oil or fat is avoided. This is one advantage of the present invention.

As described above, according to the present invention, thin metal plates of required dimensions are laminated and used to construct the frame, and predetermined holes are press-processed at required locations in each of the constituent metal plates. By combining and stacking these press-formed plates in a predetermined order, slide bearings are formed at multiple locations inside the frame, and the press-formed product is assembled by incorporating rotors at key points. Since the bearing is configured within the frame with just a single step, the machinability of the frame with the bearing part is significantly improved, productivity is also improved, and dimensional precision is also improved, making it possible to create high-quality equipment with a simple configuration. was obtained.

In accordance with the spirit of the present invention, a conventional integrated type frame is used, and the frames 20, 20' are arranged at required intervals as shown in FIG. A moving body 22 with a laminated structure is formed by connecting the slide bearings 10 by a plurality of guide shafts 21, and incorporating the slide bearings in the same manner as the frame of the previous embodiment. The frame 20,
20', necessary equipment is attached to this moving body 22, and a drive shaft 23 connected to the moving body through one frame 20' is connected to a hydraulic cylinder or an electric drive. It can be reciprocated directly in the axial direction by a machine, or by forming a threaded part on the drive shaft 23 and rotating a female threaded body (not shown) that is screwed into it using the rotational power of an electric motor, etc. By moving the movable body along the guide axis, it is easy to obtain a device that can smoothly move a movable body to which a desired device or component is attached.

Alternatively, as another example, in order to move a movable body in a straight line along a long-distance guide, the stationary body side should have a head with a circular cross section or a hexagonal cross section (or a rectangular or larger shape), as illustrated in FIGS. 8 and 9. One or more guide rails 25 (the same applies even if they are rectangular) are installed in parallel, and a rectangular space is formed that is connected radially from the central guide hole 11a in the same manner as in the previous embodiment. A slide bearing 10' having a structure in which a plurality of rotors 17 are disposed in each part 15 and a cutout part 11b is formed partially toward the outer end from the central guide hole is provided corresponding to the guide rail 25. , a movable body 26 provided with 10 slide bearings (same structure as explained in the previous embodiment) according to the arrangement of the guide shaft 27 or the lateral movement shaft (in the axial direction) is guided by the slide bearing 10'. Head 2 of rail 25
5' is inserted into the central guide hole through the cutout 11b, and the head 25' is held by the rotor 17 of the bearing 10'. By applying driving force using a drive chain, etc., it is possible to move smoothly and effortlessly even over long distances. Of course, in its construction, all the conventional problems such as no shaft contamination due to the movement of the sliding parts during driving are eliminated, and great effects can be exhibited.

Furthermore, if the above-described structure is used, a guide rail is attached along the upright surface, and the table 30 equipped with a slide bearing that engages with the guide rail 25 is connected to the lifting rod 31.
If it is raised and lowered by the slide bearing 10' which also engages with the guide rail 25,
The rotor of the rail rolls smoothly while holding the rail head, and can be raised and lowered without shaking, and therefore can be effectively used in a relatively small elevator.

In addition, in a mechanism in which one or more slide shafts or guide rails are combined with a single disc body or similar item, a press-formed plate may be combined as the disc body or similar item, and the above method may be used. By combining the required number of slide bearings into one piece, it has become extremely easy to manufacture this type of equipment, which conventionally required a lot of difficult work and had problems with productivity.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that partial changes, diversions to other devices based on the above technical idea, etc. belong to the technical scope of the present invention. Nor.
