[0002] The bearing seat is a large and extra-large bearing seat with special structure that can bear comprehensive loads. It has the characteristics of compact structure, flexible rotation, easy installation and maintenance, etc. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat.
[0003] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and other handicrafts. It is mainly used as a tool to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project test fixtures and circuit board test fixtures.
[0004] From the analysis of the above technical solutions, it can be seen that the current bearing seat processing jig, when processing the bearing seat, needs to use a core rod that matches the bearing seat to be positioned inside the bearing seat to achieve the positioning of the bearing seat, but when the size of the bearing seat changes, it needs to be readjusted, resulting in limitations in use. The positioning of the bearing seat is relatively complicated, which can easily cause the bearing seat to move, reducing the work accuracy. Utility Model Content

[0007] Furthermore, the shape of the support plate is set to be L-shaped, and the ends of the bearing seat are respectively placed on the surfaces of the two support plates.
[0008] Furthermore, a top block is arranged on the surface of the vertical plate and above the support plate.
[0009] Furthermore, a slide groove is provided on the inner wall of the movable groove, and a sliding block corresponding to the slide groove is provided on the end surface of the bottom of the vertical plate, and the sliding block is slidably installed inside the slide groove.
[0010] Furthermore, a stepper motor is provided on one side of the base via bolts, and an output end of the stepper motor is connected to the forward and reverse screw rods.
[0011] Furthermore, the horizontal height of the support plate is higher than that of the base.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model provides positive and negative threaded screws. When the positive and negative threaded screws are rotated, the two vertical plates can move to the inside or outside of the base at the same time, thereby realizing the clamping operation of the bearing seat. The operation is simple, the bearing seat is fixed more firmly, the accuracy of the use of the device and the processing efficiency are improved, and the overall device is simple to manufacture and the manufacturing cost is low.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] See also Figure 1 - Figure 3The utility model provides a technical solution: a jig for processing a bearing seat, comprising a base 1, two movable grooves 2 are symmetrically arranged on the surface of the base 1, a through groove 11 is arranged inside the base 1 and between the two movable grooves 2, positive and negative threaded screws 3 are rotatably arranged inside the two movable grooves 2, and vertical plates 4 are respectively threadedly sleeved on the end faces of the positive and negative threaded screws 3, and the two vertical plates 4 are respectively movably installed in the two movable grooves 2, and support plates 5 are fixedly arranged on the adjacent surfaces of the two vertical plates 4, and a bearing seat 9 is arranged between the two movable grooves 2. By arranging the positive and negative threaded screws 3, when the positive and negative threaded screws 3 are rotated, the two vertical plates 4 can move to the inside or outside of the base 1 at the same time, so that the clamping operation of the bearing seat 9 can be realized, the operation is simple, the fixing of the bearing seat 9 is relatively stable, the accuracy of the use of the device and the processing efficiency are improved, and the overall device is simple to manufacture and the manufacturing cost is low.
[0020] The shape of the support plate 5 is set to be L-shaped, and the ends of the bearing seat 9 are respectively placed on the surfaces of the two support plates 5. The support plate 5 supports the bearing seat 9, and a certain space is left below the two ends of the bearing seat 9 to facilitate the processing of the bearing seat 9.
[0021] A top block 6 is arranged on the surface of the vertical plate 4 and above the support plate 5. The top block 6 has a clamping effect on the bearing seat 9, ensuring the stability of the clamping of the bearing seat 9 and not damaging the vertical plate 4 body.
[0022] The inner wall of the movable groove 2 is provided with a slide groove 8, and the end surface of the bottom of the vertical plate 4 is provided with a slider 7 corresponding to the slide groove 8, and the slider 7 is slidably installed inside the slide groove 8.
