Sheet metal box inner cavity corner grinding and polishing robot production line

Abstract

The invention discloses a production line of a robot for grinding and polishing the inner cavity of a sheet metal box, which includes a transfer table, three cross slide devices, a rough polishing device, a corner grinding device and a fine polishing device; The forward sandblasting body, the rotary drive mechanism and two side sandblasting bodies; the forward sandblasting body is rotatably connected to the connecting plate, the forward sandblasting body is provided with a first chamfer, and the first chamfer is provided with A plurality of first sandblasting through holes and a plurality of first chip removal through holes; two lateral sandblasting bodies are symmetrically rotated and arranged on the left and right sides of the first chamfered part, and the lateral sandblasting body has a second chamfered part , the second chamfering part is set inclined backward, and the second chamfering part is provided with a second chip removal through hole and a plurality of second sandblasting through holes; The grinding effect of the parts can solve the problem of relatively large grinding dead angles caused by corner grinding, and avoid excessive grinding of the facade near the corners.

Description

Sheet metal box cavity edge grinding and polishing robot production line technical field [0001] The present invention relates to a robotic production line for grinding and polishing the corners of a sheet metal box cavity. Background technique [0002] The sheet metal box type parts of the rectangular body structure are the most common type of sheet metal parts in sheet metal forming products. Widely used in machinery, electronics, electricity, transportation and other fields. [0003] The sheet metal box often needs to be polished before the surface is processed, because its three corners are There are elevations in all directions, and the space is small, which makes the existing disc grinder unsuitable for grinding the corners. Due to the shielding effect of the sheet metal box, the overall sandblasting method makes the grinding effect not good, and also affects the vertical surface near the corners. The surface causes excessive sanding. SUMMARY OF THE INVENTION ...

AI Technical Summary

Problems solved by technology

[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 to the facade near the corners
