[0009] According to the above technical solution, an auxiliary device for preventing excessive vibration of the workpiece is provided on the front side of the H-shaped frame, and a dust collection device is provided on the inner wall of the processing frame. The auxiliary device includes a support rod, a U-shaped frame, a support hole, a placement hole, a placement plate and a rubber plate. The rubber plate moves toward the direction close to the workpiece to contact the side edge of the workpiece and support the side edge of the workpiece. The support rod is fixedly installed on the inner wall of the processing frame, and the U-shaped frame is slidably installed on the circumferential surface of the support rod. The support hole is opened on the front side of the H-shaped frame, and the placement hole is opened on the surface of the U-shaped frame.

A curved plate is fixedly installed on the inner wall of the dust collection device, and the S-shaped rod is in contact with the separation plate.

[0014] The present invention provides a compressor cylinder seat grinding device, which has the following beneficial effects: (1) The grinding device for the cylinder seat of the compressor can grind the inner surface of the cylinder seat. The free end of the elastic telescopic block contacts the limit hole and limits the stabilizing plate. The stabilizing plate cannot continue to squeeze the workpiece due to the limit of the free end of the elastic telescopic block. The clamping force of the stabilizing plate is controlled by the limit, so as to ensure that the clamping pressure is uniform and appropriate, thereby avoiding deformation of the workpiece and improving the subsequent processing accuracy. The shielding plate moves out of contact with the button and releases the shielding of the button. By ensuring that the workpiece is firmly clamped before the button shielding is released, the accidental start-up of the grinding device caused by human error can be reduced, thereby avoiding processing errors caused by unstable clamping.

[0015] (2) The compressor cylinder seat grinding device moves the rubber plate toward the workpiece to contact and support the side of the workpiece. The rubber plate contacts the side of the workpiece to support and stabilize the workpiece, thereby reducing the shaking of the workpiece caused by vibration, thereby maintaining the uniformity and accuracy of the grinding workpiece. The rubber plate automatically resets to break away from the contact with the workpiece, thereby facilitating the removal of the workpiece. The automatic reset of the rubber plate can reduce the time for removing and preparing the workpiece, thereby improving the overall workpiece grinding efficiency.

[0016] (3) The compressor cylinder seat grinding device pushes the larger processing waste chips on the rear side of the separation plate by rotating the S-shaped rod. The larger processing waste chips on the rear side of the separation plate are pushed by the S-shaped rod and fall to the bottom of the inner wall of the dust collection device to wait for centralized cleaning. The pushing action of the S-shaped rod can prevent the waste chips from accumulating on the surface of the separation plate, thereby effectively reducing the burden of the dust collection device and improving the dust collection efficiency. The S-shaped rod rotates to contact and squeeze the curved plate, and the S-shaped rod is deformed by the reaction force of squeezing the curved plate. The S-shaped rod is deformed by the reaction force of squeezing the curved plate, which can more effectively push the processing waste chips on the rear side of the separation plate, thereby improving the pushing effect of the S-shaped rod.

After the placement plate 175 breaks away from the contact with the linkage rod 15, the U-shaped frame 172 moves and resets in the direction away from the workpiece. The U-shaped frame 172 moves and resets, driving the rubber plate 176 to move and reset. The rubber plate 176 moves and resets to break away from the contact with the workpiece, thereby facilitating the removal of the workpiece.

[0030] The U-shaped frame 172 moves toward the direction close to the workpiece, contacts the inclined surface of the rack 185 and squeezes the rack 185. The rack 185 is squeezed by the U-shaped frame 172 and moves away from the support rod 171. The rack 185 moves away from the support rod 171 and squeezes the gear 184. The gear 184 is squeezed by the rack 185 and rotates. The rotation of the gear 184 drives the rotating rod 183 to rotate. The rotation of the rotating rod 183 squeezes the clockwork spring. The clockwork spring is squeezed by the rotating rod 183 to deform and accumulate force. At the same time, the rotation of the rotating rod 183 drives the S-shaped rod 186 to move. The S-shaped rod 186 rotates to push the larger processing waste chips on the rear side of the separation plate 182. The larger processing waste chips on the rear side of the separation plate 182 are pushed by the S-shaped rod 186 and fall to the bottom of the inner wall of the dust collection device 181 to wait for centralized cleaning.
