By setting the rotating disk 6, when the rotating disk 6 rotates, the position of multiple insert shafts 8 is adjusted through the concave and convex annular groove 7. By setting the synchronous clamping and positioning mechanism, the inner ring of the bearing body 5 is quickly clamped and positioned.

[0017] In this utility model, reference Figure 3 The synchronous clamping and positioning mechanism includes a fixed plate 4 rotatably connected to the surface of the connecting shaft 18, a connecting plate 17 fixedly connected to the lower surface of the fixed plate 4, and the surface of the connecting plate 17 fixedly connected to the surface of the slider 2.

[0018] By setting the connecting plate 17, the connection between the fixed plate 4 and the slider 2 is maintained. By setting the fixed plate 4, multiple positioning plates 9 are fixed to maintain stability.

[0019] In this utility model, reference Figure 2 Multiple positioning plates 9 are fixedly connected to the upper surface of the fixed plate 4. A moving plate 10 is slidably connected to the inner wall of the positioning plate 9. An L-shaped plate 11 is fixedly connected to one end of the moving plate 10 for clamping and supporting the bearing body 5.

[0020] The positioning plate 9 is used to maintain the sliding stability of the moving plate 10, and the L-shaped plate 11 is used to support and clamp the surface of the bearing body 5.

[0021] In this utility model, reference Figure 2 The inner wall of the motion plate 10 is fixedly connected with a shaft 8. The diameter of the shaft 8 is the same as the width of the inner wall of the concave-convex annular groove 7. The shaft 8 is installed inside the concave-convex annular groove 7.

[0022] By setting the concave and convex annular groove 7, space is provided for the insertion shaft 8 to be installed and plugged in. By setting the insertion shaft 8, the moving plate 10 is driven to slide under force.

The rotating disk 6 rotates through the concave and convex annular groove 7, changing the position of the insertion shaft 8 in the concave and convex annular groove 7. Through the motion plate 10, the position of the corresponding L-shaped plate 11 is changed. Multiple L-shaped plates 11 press against the inner surface of the bearing body 5 to keep the bearing body 5 clamped stably, which facilitates the processing of the bearing body 5. When it is necessary to change the processing direction of the bearing body 5, the positioning pin 16 is slid outward and pulled out to release the insertion state with the slot 13. After the sliding slider 2 is in a suitable position in the arc-shaped cylinder 3, the return spring 15 keeps the positioning pin 16 inserted into the corresponding slot 13 stably.
