Small-angle-position polishing machine

Abstract

The invention discloses a small-angle-position polishing machine which comprises a machine frame. A motor is fixedly installed at one side of the top end of the machine frame, a motor output shaft isin transmission connection with the motor, a driving wheel is fixedly installed at the motor output shaft, a driven wheel is movably installed at the other side of the top end of the machine frame, and the diameter of the driven wheel is smaller than that of the driving wheel; and abrasive belts are in transmission connection between the driving wheel and the driven wheel. According to the small-angle-position polishing machine, the small-diameter driven wheel is matched with the driving wheel to install the polishing abrasive belts, and small-area planes, cavities, arc surfaces, fine gaps, included angles, groove surfaces and other narrow positions of metal parts can be ground and polished through the abrasive belts on the arc surface of the small-diameter driven wheel, so that small-angle polishing work is achieved; the two sets of polishing abrasive belts are installed through a double-shaft motor, so that the polishing efficiency can be improved; meanwhile, the double-shaft motor can adopt a double-shaft-extension asynchronous motor to drive the two polishing abrasive belts to conduct transmission at different rotating speeds, rough grinding and fine grinding are conducted on the metal piece, and therefore the polishing effect of the metal pieces is improved.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a small-angle polishing machine. Background technique [0002] Generally, after the metal workpiece is processed and shaped, there will be burrs or scratches on the surface, which will affect the use. Therefore, a polishing machine is required to polish the surface of the metal workpiece. The current polishing machines mainly include circular tube polishing machines, disc polishing machines, CNC polishing machines, etc. Most of them are suitable for grinding and polishing large-area metal parts, but not suitable for small-area planes, cavities, arc surfaces, etc. Grinding and polishing of small gaps, angles, groove surfaces and other narrow positions. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a small-angle polishing machine. The polishing belt is installed through a small-diameter roller, and the small-area p...
