Fixation-free auxiliary device capable of uniformly polishing annular workpieces

Abstract

The invention relates to the technical field of computer spare and accessory parts, and discloses a fixation-free auxiliary device capable of uniformly polishing annular workpieces. The fixation-free auxiliary device comprises a grinding machine, and the surface of the grinding machine is rotatably connected with a first rotating rod. According to the fixation-free auxiliary device capable of uniformly polishing the annular workpieces, a first rotating rod rotates to drive a first gear and a second gear to rotate, so that a second rotating rod intermittently drives a first connecting rod and a second connecting rod to rotate, and two polishing discs with the same rotating direction approach the workpieces at a constant speed for polishing; the first gear rotates to drive a third gear to rotate, the third gear is meshed with a gear rack to drive the gear rack to slide on the surface of a guide rail, and intermittent sliding of the gear rack drives a gear mechanism arranged on the back face of a carrying disc to rotate, so that when a grinding disc gets close to a workpiece on the surface of the carrying disc, the carrying disc rotates in the reverse direction of rotation of the grinding disc, and thus, the grinding amount is increased, and the effects of rapidly, effectively and quantitatively grinding the annular workpieces and improving the workpiece grinding efficiency and quality are achieved.

Description

technical field [0001] The invention relates to the technical field of computer spare parts, in particular to an auxiliary device for evenly grinding ring-shaped workpieces without fixing. Background technique [0002] The processing of computer spare parts is mostly made by turning, milling, planing, drilling, grinding and other processes. Since the workpiece will have burrs and other defects on the edge when drilling or cutting, it needs to be rounded by grinding, especially Especially for ring-shaped workpieces, if the burrs are not removed cleanly, it is easy to cause the joints to be not tight, which will affect the normal operation of the workpieces. [0003] Traditionally, the grinding of some ring-shaped computer parts such as cooling fan frames, fastening collars, etc. is carried out by manually operating a hand-held grinder. Because the workpiece is ring-shaped, it is difficult to grasp the amount of grinding by hand, and it is easy to cause the surface thickness o...
