Robot production line for grinding and polishing corners of inner cavity of metal plate box

Abstract

The invention discloses a robot production line for grinding and polishing corners of an inner cavity of a metal plate box. The robot production line comprises a conveying table, three cross-shaped sliding table devices, a rough polishing device, a corner grinding device and a fine polishing device, wherein the corner grinding device comprises a connecting plate, a forward sand blasting body, a rotary driving mechanism and two lateral sand blasting bodies; the forward sand blasting body is rotationally connected to the connecting plate and provided with a first chamfering part; the first chamfering part is provided with a plurality of first sand blasting through holes and a plurality of first chip removal through holes; the two lateral sand blasting bodies are symmetrically and rotationally arranged on the left side and the right side of the first chamfering part; and each lateral sand blasting body is provided with a second chamfering part, wherein the second chamfering part is obliquely arranged backwards and provided with a second chip removal through hole and a plurality of second sand blasting through holes. According to the robot production line, the grinding area range is enlarged, the grinding effect on the corners of the inner cavity of the metal plate box is improved, the problem that the grinding dead angle generated by corner grinding is large is solved, and excessive grinding on the vertical faces near the corners is avoided.

Description

technical field [0001] The invention relates to a production line of a robot for grinding and polishing the inner cavity of a sheet metal box. Background technique [0002] Sheet metal box parts with a rectangular structure are the most common type of sheet metal parts in sheet metal forming products, and are widely used in various fields such as machinery, electronics, electricity, and transportation. [0003] Sheet metal cabinets often need to be polished before the surface is processed. Since the corners have elevations in three directions and the space is small, the existing disc grinder cannot be used for grinding the corners. However, due to the shielding effect of the facade of the sheet metal box in the overall sandblasting method, the grinding effect is not good, and it will also cause excessive grinding of the facade near the corners. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings, and prov...
