Sandblasted sheet metal box cavity edge grinding robot arm

Abstract

The invention discloses a sandblasting type sheet metal box inner cavity edge grinding mechanical arm, which comprises a connecting plate, a positive sandblasting body, a rotary drive mechanism and two side sandblasting bodies; the positive sandblasting body is rotatably connected to the On the connecting plate, the positive sandblasting body is provided with a first chamfering portion at the junction of its front surface and the bottom surface, and the first chamfering portion is provided with a plurality of first sandblasting through holes and a plurality of first chip evacuation through holes. A first sand blasting through hole and a plurality of first chip evacuation through holes are arranged at intervals; two lateral sand blasting bodies are symmetrically arranged on the left and right sides of the first chamfering part, and the lateral sand blasting body has a second chamfering body. The corner portion, the second chamfered portion is inclined backward, the second chamfered portion is provided with a second chip evacuation through hole and a plurality of second sand blasting through holes, and the plurality of second sand blasting through holes are dispersedly arranged; the invention improves the The scope of the grinding area and the grinding effect of the corners of the inner cavity of the sheet metal box can be improved to solve the problem of large dead corners caused by corner grinding, and avoid excessive grinding of the elevation near the corners.

Description

technical field [0001] The invention relates to a sandblasting type sheet metal box inner cavity edge and corner grinding mechanical arm. 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 machinery, electronics, electricity, transportation and other fields. [0003] The sheet metal box often needs to be ground before the surface is treated. Since the corners have vertical faces in three directions, the space is small, so the existing disc grinder cannot be used for grinding the corners. However, the overall sandblasting method has poor grinding effect due to the shielding effect of the sheet metal box façade, and also causes excessive grinding of the façade near the corners. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a sandblasting type mechanical arm for...

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
