[0022] An electric push rod 2 is movably connected to the right side of the L-shaped plate 4 via a rotating shaft and bearing. The right end of the electric push rod 2 is bolted to the left side of the double-headed electric cylinder 8. A rotary motor 3 is bolted to the left side of the L-shaped plate 4, and the left end of the rotating shaft on the electric push rod 2 passes through the inner ring of the bearing and connects to the output shaft of the rotary motor 3. A drive motor 6 is bolted to the front side of the U-shaped plate 7, and the front end of the rotating shaft on the front side of the U-shaped clamping block 5 passes through the inner ring of the bearing and connects to the output shaft of the drive motor 6. This structure allows for effective position switching, enabling it to adapt to the inner and outer clamping of deep groove ball bearing rings, thus improving its clamping efficiency and applicability.

[0023] The platform 1 has a mounting groove 14, and a movable block 13 is slidably connected within the mounting groove 14. A support column 9 is movably connected to the top of the movable block 13 via a bearing.

[0024] Working principle: In use, the two U-shaped clamping blocks 5 are first placed inside the deep groove ball bearing race. The push rods on the top and bottom of the double-headed electric cylinder 6 extend, causing the two U-shaped clamping blocks 5 to clamp the deep groove ball bearing race. The extension and retraction of the electric push rod 2 can drive the deep groove ball bearing race to slide to the right or left through the double-headed electric cylinder 8, U-shaped plate 7, and U-shaped clamping blocks 5. The rotary motor 3 drives the deep groove ball bearing race to swing back and forth through the electric push rod 2, double-headed electric cylinder 8, U-shaped plate 7, and U-shaped clamping blocks 5. The extension and retraction of the electric jack 11 is achieved through the movable block 13, support column 9, L-shaped plate 4, electric push rod 2, double-headed electric cylinder 8, U-shaped plate 7, and... The U-shaped clamping block 5 drives the deep groove ball bearing race to move up or down. The servo motor 10 drives the deep groove ball bearing race to rotate left and right through the support column 9, L-shaped plate 4, electric push rod 2, double-headed electric cylinder 8, U-shaped plate 7 and U-shaped clamping block 5, so that it can be conveniently adjusted in direction and angle, making it suitable for the processing of grinding parts and improving its usage efficiency and working efficiency.

Repeating the above operation allows for effective position switching, thereby adapting to the inner and outer clamping of the deep groove ball bearing race, improving its clamping efficiency and application range.
