[0002] The idler wheel bracket is a key component of tracked construction machinery and other equipment. It typically consists of a bracket body that provides support and positioning, and a mounting base for mounting the idler wheels. During the processing of the idler wheel bracket, multiple surfaces and holes need to be milled, drilled, and bored. To prevent the idler wheel bracket from shifting during processing, it needs to be clamped and positioned using a fixture.

For guide wheel brackets of different specifications and models, fixtures often need to be redesigned and manufactured, which increases production costs and time. At the same time, the clamping operation is cumbersome, time-consuming, and affects processing efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-6 A guide wheel bracket processing fixture includes a processing base 1, an mounting plate 2 fixedly mounted on the upper surface of the processing base 1, a mounting groove formed on the side wall of the processing base 1, a sliding opening 3 connected to the mounting groove formed on the upper surface of the processing base 1, a T-shaped clamping plate 4 symmetrically slidably mounted in the sliding opening 3, a first threaded rod 5 horizontally rotatably mounted in the mounting groove, a U-shaped sliding plate 6 threaded onto the first threaded rod 5, a connecting rod symmetrically fixedly mounted on the surface of the sliding plate 6, an I-shaped block 7 fixedly mounted at one end of the connecting rod, an inclined plate 8 fixedly mounted on the bottom surface of the clamping plate 4, a sliding opening formed on the surface of the inclined plate 8, and two I-shaped blocks 7 slidably disposed in the two sliding openings respectively.

[0025] The surface of the mounting plate 2 is symmetrically provided with rotating openings. A rotating rod 9 is horizontally rotatably installed in the rotating opening. A stop plate 10 is fixedly installed on the surface of the rotating rod 9. The two rotating rods 9 are controlled to rotate relative to each other by a transmission component. The transmission component includes a second threaded rod 11 horizontally rotatably installed on the surface of the mounting plate 2, a sliding plate 12 threadedly sleeved on the second threaded rod 11, and two third threaded rods 13 symmetrically fixedly installed on the surface of the sliding plate 12. The threads on the surfaces of the two third threaded rods 13 are opposite in direction. One end of the rotating rod 9 is provided with a threaded groove 14, and one end of the two third threaded rods 13 is respectively threaded into the two threaded grooves 14.

[0026] First, place the guide wheel bracket to be clamped on the upper surface of the machining base 1, positioning it between the two clamping plates 4. Then, control one end of the bracket to abut against the surface of the mounting plate 2. Next, rotate the first threaded rod 5, controlling the sliding plate 6, which is threaded onto the first threaded rod 5, to move the two I-shaped blocks 7 laterally. The two I-shaped blocks 7 will slide within their respective sliding openings, and the surfaces of the I-shaped blocks 7 will slide into contact with the surfaces of the inclined plates 8. Under the pressure of the inclined plates, the two clamping plates 4 will move relative to each other until the two clamping plates 4 are firmly abutted against the surfaces of the guide wheel bracket, thus completing the clamping of the guide wheel. The bracket is laterally clamped and positioned. Then, the second threaded rod 11 is rotated, controlling the sliding plate 12 to move laterally along the two third threaded rods 13. Since the third threaded rods 13 cannot rotate, the two rotating rods 9 will rotate relative to each other along with the two abutment plates 10 under the cooperation between the threads on the surface of the third threaded rods 13 and the groove wall of the threaded groove 14. The vertical pressing and positioning of the guide wheel bracket is completed after the two abutment plates 10 are tightly abutted against the guide wheel bracket. This can meet the positioning of guide wheel brackets of different specifications and models, improve the versatility of the fixture, and is easy to operate, thus improving processing efficiency.

[0027] The upper surface of the machining base 1 is provided with a transverse groove. The transverse groove is provided with a limiting component for cooperating with the mounting plate 2. The limiting component is used to restrict the movement of the guide wheel bracket. The limiting component includes a fourth threaded rod 15 that is horizontally rotatably installed in the transverse groove and a limiting plate 16 that is threaded onto the fourth threaded rod 15. A rotating shaft is horizontally rotatably installed on one side of the machining base 1. One end of the rotating shaft passes into the transverse groove and is fixedly connected to one end of the fourth threaded rod 15. The bottom wall of the limiting plate 16 slides in contact with the bottom of the transverse groove, which can restrict the rotation of the limiting plate 16, so that the limiting plate 16 can only move laterally in the transverse groove. The bottom of the transverse groove is coated with polytetrafluoroethylene paint. Polytetrafluoroethylene can reduce the friction between the limiting plate 16 and the contact surface of the transverse groove.

[0028] After the guide wheel bracket is positioned laterally and vertically, the fourth threaded rod 15 can be rotated by rotating the rotating shaft. This causes the limiting plate 16, which is threaded onto the fourth threaded rod 15, to move laterally within the transverse groove until the surface of the limiting plate 16 is tightly abutted against the end of the guide wheel bracket away from the mounting plate 2. At this point, the guide wheel bracket will be located between the mounting plate 2 and the limiting plate 16, thereby limiting the lateral movement of the guide wheel bracket and enhancing the positioning stability of the guide wheel bracket.

[0029] The surfaces of mounting plate 2, clamping plate 4, abutment plate 10, and movement limiting plate 16 are all bonded with an anti-slip layer. The anti-slip layer is made of rubber. The rubber anti-slip layer has good elasticity and adhesion, which can increase the friction between the mounting plate 2, clamping plate 4, abutment plate 10, and movement limiting plate 16 and the contact surface of the guide wheel bracket, while also preventing damage to the surface of the guide wheel bracket due to pressure.

[0030] In this utility model, through the cooperation between the first threaded rod 5, the I-shaped block 7, and the inclined plate 8, and the action of the transmission components, the distance between the two clamping plates 4 can be quickly adjusted and the rotation of the two abutment plates 10 can be controlled, thereby satisfying the lateral clamping and positioning and vertical pressing positioning of guide wheel brackets of different specifications and models, improving the versatility of the fixture, simplifying operation, and improving processing efficiency.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
