Sand blasting machine provided with polishing wheel for polishing burr

Abstract

The invention discloses a sand blasting machine provided with a polishing wheel for polishing burr. The sand blasting machine comprises a rack, the polishing wheel and a sand blasting chamber, whereinthe sand blasting chamber is arranged on the rack; two elevating mechanisms are symmetrically arranged on the left side and the right side of the top end of the inside of the sand blasting chamber; the polishing wheel and a sand storage cylinder are respectively arranged at the lower ends of the two elevating mechanisms; the polishing wheel comprises a rotating motor arranged at the lower ends ofthe elevating mechanisms and a polishing piece coaxially and rotatably connected with the rotating motor; a water storage tank is arranged on one side of the polishing wheel; an air bag for extrusionis arranged at the upper end of the water storage tank in a through connection manner; a water discharge pipe is guided out of the lower end of the water storage tank; a nozzle is arranged at the lower end of the water discharge pipe and inclines to the polishing piece; a spray gun is connected with the lower end of the sand storage cylinder by a material guide hose. Through adoption of the manner, the burr on the surface of a workpiece, which cannot be removed in sand blasting, can be auxiliarily polished by the polishing wheel.

Description

technical field [0001] The invention relates to the field of sand blasting machines, in particular to a sand blasting machine with a grinding wheel for assisting in grinding burrs. Background technique [0002] Sand blasting machine is the category of air conveying machinery. It uses compressed air to transport powdery granular materials from one place to another in the pipeline, and during the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object. To achieve the effect of improving the surface quality of the object, when the traditional sandblasting machine blasts some workpieces with burrs on the surface, some hard burrs cannot be removed by sandblasting, and the residues on the surface of the workpiece affect its sandblasting quality. Dedicated equipment to polish these burrs. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a sand...
