[0022] The two rotating shafts 22 are started and driven to rotate by the bidirectional motor 21, thereby rotating the two bevel gears 23. The rotation of the bevel gear 23 drives the bevel gear 24 to rotate, thereby rotating the rotating rod 25 and driving the connecting shaft 26 to rotate on the inner wall of the circular through hole. The two connecting shafts 26 rotate to rotate the two spiral rods 27 at the bottom of the protrusion of the L-shaped fixed plate 29, and drive the slider 28 to move up and down on the outer wall of the spiral rod 27. The up and down movement of the two sliders 28 drives the fixed structure 4 to move up and down, thereby causing the two sliding sleeves 33 to slide on the outer wall of the sliding rod 32, thereby achieving up and down movement as needed during the processing of the bearing bushing, and realizing precise processing thickness control.

[0025] The following is a detailed description of the working principle of the fixing fixture used for machining bearing bushings.

[0026] like Figure 1-5 As shown, the fixing fixture used for the machining of the bearing bushing can be moved up and down as needed during the machining of the bearing bushing by adjusting the structure 2 and the connecting structure 3, so as to realize precise control of the machining thickness, and make the machining thickness adjustment of the bearing bushing machine more convenient and quick, thereby improving the flexibility of the equipment and the machining accuracy of the product, being adaptable to the machining of bearing bushings of different specifications and types, and improving the versatility of the equipment. The fixing fixture used for the machining of the bearing bushing can be stably clamped by the fixing structure 4, and has a simple structure and convenient operation. The two rotating shafts 22 are started and driven to rotate by the bidirectional motor 21, thereby rotating the two bevel gears 1 23, and the rotation of the bevel gear 1 23 drives the bevel gear 2 24 to rotate, thereby rotating the rotating rod 25 and driving the connecting shaft 1 26 to rotate on the inner wall of the circular through hole, and the two connecting shafts 1 26 are rotated to make the two spiral rods 27 rotate at the bottom of the protrusion of the L-shaped fixing plate 1 29.

The stepper motor 44 is started and drives the bidirectional threaded rod 46 to rotate inside the support sleeve 47, so that the two sliders 48 move inward and outward on the outer wall of the bidirectional threaded rod 46 at the same time. The movement of the two sliders 48 drives the two clamping blocks 401 to move inward and outward at the same time, and then drives the two sleeves 40 to slide on the outer wall of the slide rod 49. The rubber block 402 contacts the outer wall of the bearing bushing to prevent the outer wall of the bearing bushing from being damaged when the bearing bushing is clamped and fixed, thereby further achieving the effect of stably clamping the bearing bushing, with a simple structure and convenient operation.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
