Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fixing device used when fixing a device on a surface plate with a T groove.
[0002]
[Prior art]
FIG. 3 shows a T-slot surface plate in which a plurality of T-slots 4 are provided. 1a shows a surface view and 1b shows a side view. The T-groove 4 is provided with a notch 5 which is usually called a piece drop. When fixing a device 10 such as a test facility on the T-groove surface plate, a T-nut 7 as shown in FIG. 4 is fixed. After being inserted into the T-groove 4 from the notch 5 of the board, it is fixed with a foundation bolt 6. When it is necessary to move the apparatus on the surface plate for some reason, a boat-shaped T-nut 8 as shown in FIG. The shape of the nut differs depending on whether the device needs to be moved or not. When a T-nut 7 is used, the T-groove 4 generally has a notch for dropping the T-nut 7 into the T-groove 4. 5 is provided in several places of the T-slot 4, and the notch 5 is equal to or larger than the wide part of the lower part of the T-slot, so that when the T-nut 7 passes there This is because it is displaced from the axial direction of the T-groove and is caught by the notch 5 to obstruct the movement of the device, and when it is moved, it is necessary to use the boat-shaped T-nut 8.
[0003]
[Problems to be solved by the invention]
FIG. 6 shows the state of use of the boat-shaped T-nut 8. When this boat-shaped T-nut 8 is used, where the space 9 for inserting the boat-shaped T-nut for inserting the boat-shaped T-nut 8 into the T-slot 4 is shown. It is necessary to prepare it. In general, it will be both ends or one end of the surface plate. As a result, the size of the surface plate becomes larger by the space for inserting the boat-shaped T-nut 9 than the size required for installing the equipment, and the space 9 for inserting the boat-shaped T-nut already exists on both ends or one side of the surface plate. If the T-groove surface plate is installed without any additional work, additional work will occur.
[0004]
As described above, in the conventional T-nut 7, the boat-shaped T-nut 8 is caught in the notch 5 when the T-nut 7 reaches the portion of the notch 5 provided in the T-slot 4 of the surface plate. However, there is a problem that the installation space of the surface plate becomes large or cannot be used as it is when it is installed on an existing surface plate.
[0005]
The first of the present invention is for fixing a device to a T-slot surface plate having a plurality of T-slots and a notch formed in an arbitrary part of the T-slot and formed larger than the surface width of the T-slot. In the fixing device,
Two nuts inserted through the notch and having a detent member implanted in a part thereof;
A T-shaped member is provided which is connected to a rectangular portion inserted from the surface of the T-groove, and has a convex portion which is inserted from the notch at a substantially central portion, and for fixing the device at a substantially central portion of the T-shaped member. A screw hole to be screwed with the foundation bolt, and an engagement hole for the through hole and the rotation preventing member on the left and right in the longitudinal direction of the T-shaped member along the T groove ,
A fixing device for fixing an apparatus to a surface plate, wherein the nuts and the T-shaped member are fixed with fixing bolts.
[0006]
A second aspect of the present invention is a fixing device for fixing an apparatus to a surface plate, wherein the rotation preventing member is a spring pin.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. 1 is an exploded perspective view for explaining a use state, and FIG. 2 is a perspective view of a nut.
[0008]
The combined boat-shaped T-nut of the present invention is configured by a combination of a T-shaped member 1 having a convex portion 1 a at a substantially central portion, a fixing bolt 2 and a nut 3. The T-shaped member 1 is formed in a rectangular shape, and through holes 1b are formed on the left and right sides thereof. The width dimension of the T-shaped member 1 is larger than the width of the T-groove 4 formed in the surface of the surface plate. It has a slightly small width dimension and is inserted into the T-groove 4. The convex portion 1a provided at the substantially central portion is formed in a plate shape or a circular shape having a diameter smaller than that of the notch 5 and larger than that of the surface plate surface groove portion of the T groove 4, and this convex portion. 1 a is inserted through the notch 5 so as to be movable along the T-groove 4. Further, a screw hole 1c penetrating the T-shaped member 1 and the convex portion 1a is screwed at the position of the convex portion 1a.
[0009]
As shown in FIG. 2, the nut 3 has, for example, a round shape and can be inserted into and removed from the notch 5, but is formed in a size that does not come out of the T-groove 4 and is a spring pin 3a as a detent member. Has been planted. The T-shaped member 1 has a hole for fitting with the pin 3a.
[0010]
Next, the case where the apparatus 10 is fixed on a surface plate will be described. First, the device 10 is placed on the T-slot surface plate so that the hole for passing the foundation bolt 6 drilled in the device 10 is directly above the T-slot 4.
One nut 3 is inserted into the wide portion of the T-slot 4 from the circular notch 5 in the T-slot 4 with the non-rotating spring pin 3a up, and then a convex portion in the same notch 5 While placing 1a, insert the T-shaped member 1 into the narrow part of the T-groove and the lower plate into the wide part of the T-groove 4, and then install the other nut 3 in the same manner as described above. Insert into the T-slot.
[0011]
Next, the fixing bolt 2 is inserted into the hole 1b at both ends of the T-shaped member 1 from above, and the T-shaped member is screwed into the cylindrical nut 3 inserted into the T-groove 4 with the fixing bolt 2. Assemble to 1. The combined T-shaped member 1 and the round nut 3 are moved until the screw hole 1c screwed at the position of the convex portion 1a is directly below the hole for passing the foundation bolt 6 formed in the device 10. .
[0012]
After the combined T-shaped member 1 and the round nut 3 reach the above position, the base bolt 6 is passed through the hole for the base bolt of the device 10, and the base bolt is inserted into the screw hole 1c screwed at the position of the convex portion 1a. Screw 6 in place. When moving the equipment, when the foundation bolt 6 is loosened, the combined T-shaped member 1 and the round nut 3 move along the T-groove by moving in the T-groove.
[0013]
In addition, by using a spring pin as the rotation stopper, the influence of catching when the nut 3 passes through the cylindrical notch 5 is further reduced.
[0014]
【The invention's effect】
Thus, according to the present invention, the boat-shaped T-nut for fixing is assembled by using the cylindrical notch 5 provided in the T-groove 4. 9 is unnecessary. As a result, the space for installing the surface plate can be reduced, and the mobile device can be fixed using the already-set plate without the boat-shaped T-nut insertion space 9 as it is. In addition, conventionally, when there is no space, it has been necessary to dig the floors before and after the surface plate to make a boat-shaped T-nut insertion space 9, but in the present invention, such work is unnecessary, It is very useful in terms of cost and construction period.
Also, by attaching two round nuts 3 to the front and rear of the T-shaped member 1, there are effects such as enabling smooth movement of the device in the left-right direction.
