Description

Technical Field

[0001] The utility model relates to the technical field of metal polishing, in particular to a self-adaptive pressing device for metal surface polishing. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical and electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss.

[0003] The existing utility model with authorization announcement number CN213917739U discloses a metal surface polishing device, including a base, with limited sliding holes on both sides of the top of the base, a pull rod fixedly connected to the top of the inner cavity of the base, a motor fixedly connected to the bottom of the pull rod, a gear fixedly connected to the output shaft of the motor, a first tooth plate and a second tooth plate engaged with the top and bottom of the gear respectively, a movable rod fixedly connected to one side of the first tooth plate and the second tooth plate, the top of the movable rod extends to the outside of the limited sliding hole, and is fixedly connected to a splint.

[0004] By adopting the above technical solution, the gear is driven to rotate by the output shaft of the motor, and the gear meshes with the teeth on the surface of the first tooth plate and the second tooth plate, thereby driving the first tooth plate and the second tooth plate to move. The movement of the first tooth plate and the second tooth plate drives the movable rod and the clamping plate to move, and the clamping plate fixes the workpiece, which solves the problem that the existing polishing device lacks fixation of the workpiece, so the workpiece will be displaced during the polishing process, which not only reduces the polishing efficiency but is also more dangerous. However, the above technical solution can only fix the metal workpiece through the clamping plate, and cannot adjust the clamping force according to the actual situation of the metal surface. It is easy to cause uneven polishing, surface scratches and poor polishing effect due to excessive or insufficient pressure.

[0005] Therefore, those skilled in the art provide a metal surface polishing adaptive pressing device to solve the problems raised in the above background technology. Utility Model Content
