At this time, the first motor 2 drives the transmission rod 7, so that the second gear 8 and the third gear 22 welded on the transmission rod 7 rotate, thereby driving the first gear 9 and the fourth gear 23. Driven by the gears, the first grinding rod 11 and the second grinding rod 24 start to operate and grind the contact surface of the spring bushing.
[0018] Please refer to Figures 1-3As shown in the figure, there is a spring bushing processing and grinding device. The transmission rod of the second motor 21 is connected to the stretching rod 17. The other end of the stretching rod 17 is welded with a transmission shaft 18. One end of the transmission shaft 18 is provided with a bushing support 19. There are holes inside the bushing support 19, and threaded holes 20 are provided on the inner wall of the holes. There are buckles on the surface of the transmission shaft 18, and it is in a connection relationship with the bushing support 19. On the other side of the box body 1, there is a fixed seat 3.

The surface materials of the first grinding rod 11 and the second grinding rod 24 are rough abrasive materials. The thread diameter of the screw rod 4 is the same as the diameter of the threaded hole 20 on the inner wall of the bushing support 19. During the processing, the operator starts the second motor 21. When the motor drives the stretching rod 17, it pushes the bushing support forward. At this time, the screw rod 4 enters the threaded hole 20 inside the bushing support 19 and drives the bushing support 19 to start rotating. At this time, the first grinding rod 11 and the second grinding rod 24 jointly grind the protruding part. When the bushing support 19 reaches a fixed point, the stretching rod 17 pulls back the bushing support 19 and the first grinding rod 11 and the second grinding rod 24 grind the pulled-back part, thereby performing all-round grinding on the spring bushing.
[0019] Working principle: When grinding the surface of the spring bushing, the operator first puts the spring bushing to be ground on the outside of the bushing support 19 according to needs, and then slides the slider 13 to adjust the distance between the first grinding rod 11 and the second grinding rod 24 so that the surfaces of the first grinding rod 11 and the second grinding rod 24 can closely adhere to the spring bushing. Then, the first motor 2 and the second motor 21 are started. At this time, the first motor 2 drives the transmission rod 7, causing the second gear 8 and the third gear 22 welded on the transmission rod 7 to rotate, thereby driving the first gear 9 and the fourth gear 23. Driven by the gears, the first grinding rod 11 and the second grinding rod 24 start to operate and grind the contact surface of the spring bushing. During the processing, the operator starts the second motor 21. When the motor drives the stretching rod 17, it pushes the bushing support forward. At this time, the screw rod 4 enters the threaded hole 20 inside the bushing support 19 and drives the bushing support 19 to start rotating. At this time, the first grinding rod 11 and the second grinding rod 24 jointly grind the protruding part. When the bushing support 19 reaches a fixed point, the stretching rod 17 pulls back the bushing support 19 and the first grinding rod 11 and the second grinding rod 24 grind the pulled-back part, thereby performing all-round grinding on the spring bushing.
