[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-3 , an integral thrust PEEK bearing bush includes a bearing bush body 1 and a thrust piece 2 provided at its upper end. A plurality of support rods 4 are fixedly connected to the upper end of the bearing bush body 1 for supporting the thrust piece 2. The lower end of the thrust piece 2 is provided with slots corresponding to the support rods 4. The upper ends of the support rods 4 slide and extend into the slots. The number of support rods 4 is multiple to improve the support effect. An oil groove 10 is provided at the lower end of the bearing bush body 1 for circulating lubricating oil;

[0021] In this embodiment, a plurality of positioning rods 3 are fixedly connected to the upper end of the bearing shell body 1 and are used to cooperate with the positioning grooves to position the thrust washer 2. The upper end of the positioning rod 3 is conical in shape to facilitate the insertion of the positioning rod 3 into the positioning groove. The lower end of the thrust washer 2 is provided with a positioning groove corresponding to the positioning rod 3. The upper end of the positioning rod 3 slidably extends into the positioning groove. A chute is provided in the positioning rod 3, and two sliders 5 are slidably connected to the inner side wall of the chute and are used to drive the clamping block 6 to move. A horizontally arranged guide rod 8 is provided between the two sliders 5 and is used to guide the movement of the sliders 5. The two ends of the guide rod 8 respectively slidably penetrate through the two sliders 5 and are fixedly connected to the inner side wall of the chute. Arc-shaped grooves are provided at both the upper and lower ends of the slider 5, and balls 9 are rotatably connected to the inner side wall of the arc-shaped grooves to reduce the resistance when the slider 5 moves. A part of the ball 9 penetrates through the arc-shaped groove;

[0022] In this embodiment, a spring 7 is fixedly connected between the two sliders 5 and is used to elastically support the sliders 5. A clamping block 6 is fixedly connected to the side of the slider 5 away from the spring 7 and is used to cooperate with the clamping groove to lock the position of the positioning rod 3. A clamping groove corresponding to the clamping block 6 is provided on the inner side wall of the positioning groove. The end of the clamping block 6 away from the slider 5 slidably penetrates through the positioning rod 3 and slidably extends into the clamping groove. The end of the clamping block 6 extending into the clamping groove is of a semi-circular structure.

[0023] In this embodiment, first, the thrust washer 2 is pushed upward to fit with the bearing shell body 1. During the downward movement of the thrust washer 2, the positioning rod 3 will be inserted upward into the positioning groove to position the thrust washer 2 and prevent the thrust washer 2 from being skewed, ensuring the accuracy when the thrust washer 2 is welded to the bearing shell body 1 subsequently. During the insertion process of the positioning rod 3, the semi-circular surface of the clamping block 6 will abut against the thrust washer 2. Affected by the downward thrust, the thrust washer 2 is used to push the clamping block 6 to move in the direction of the chute. The clamping block 6 drives the slider 5 to move, and the slider 5 compresses the spring 7. When the lower end of the thrust washer 2 is in contact with the bearing shell body 1, the positioning rod 3 is also inserted in place. At this time, the spring 7 elastically pushes the slider 5 to move, and the slider 5 drives the clamping block 6 to move and insert into the clamping groove, thereby locking the position of the positioning rod 3, and further locking the position of the thrust washer 2, ensuring the stability during the subsequent welding of the thrust washer 2 and further preventing it from loosening and skewing.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
