[0018] A grinding device for spring bushing processing, characterized in that it includes a frame 2, a first drive motor 3 is fixedly connected to the upper end of the frame 2, a grinding frame 4 is fixedly connected to the output shaft of the first drive motor 3, two sliders 5 are fixedly connected to the grinding frame 4, a grinding roller 6 is provided at the lower end of the slider 5, and the grinding frame 4 is also provided with a first push rod motor 7 for driving the slider 5 to move, a second push rod motor 8 is fixedly connected to the lower end of the frame 2, a second drive motor 9 is fixedly connected to the push rod of the second push rod motor 8, a support frame 10 is fixedly connected to the output shaft of the second drive motor 9, a clamping assembly is provided on the support frame 10, and a placement table 11 is also fixedly connected to the lower end of the frame 2.

[0019] In this embodiment, the spring bushing to be polished is placed on the placement table 11 and clamped by the clamping assembly. The second push rod motor 8 drives the second drive motor 9, the support frame 10 and the spring bushing to rise. According to the size of the spring bushing to be polished and the wall thickness of the spring bushing, the slider 5 is driven to move by the first push rod motor 7 to adjust the positions of the two polishing rollers 6 so that one polishing roller 6 can abut against the inner wall of the spring sleeve and the other polishing roller 6 can abut against the outer wall of the spring sleeve. Then the first drive motor 3 The grinding frame 4 is driven to rotate, so that the grinding roller 6 also rotates, and the two grinding rollers 6 grind the inner wall and the outer wall respectively. After grinding, the second push rod motor 8 drives the spring bushing to descend, and then the second drive motor 9 drives the support frame 10 to flip, the clamping assembly releases the spring bushing, and the spring bushing falls on the placement table 11, and the end of the spring bushing that has just been clamped faces upward, and then the support frame 10 descends again, and the clamping assembly clamps the end that has been polished, and the support frame 10 rises to polish the unpolished end. The grinding device adjusts the position of the grinding roller 6 through the first push rod motor 7 to adapt to spring bushings of different sizes and wall thicknesses.
