Sand blasting device protecting blind hole of elastic body against sand setting

Abstract

The invention discloses a sand blasting device protecting a blind hole of an elastic body against sand setting. The sand blasting device protecting the blind hole of the elastic body against sand setting is characterized by comprising a sand blasting bin, a workpiece conveying piece, sand blasting guns, a workpiece clamp, a travel switch and a PLC, wherein the sand blasting bin is provided with a feeding opening and a discharging opening, the workpiece conveying device penetrates the feeding opening and the discharging opening, the sand blasting guns are arranged below the workpiece conveying device and located inside the sand blasting bin, the workpiece clamp is placed on the workpiece conveying device, and the travel switch is arranged on the side edge of the workpiece conveying device and located inside the sand blasting bin. The sand blasting device protecting the blind hole of the elastic body against sand setting avoids the problem that in the prior art, because a clamp and a locating device are not arranged, sand blasting operation at a specific position of a workpiece cannot be achieved; and meanwhile, inverted type sand blasting is adopted, so that the blind hole of the elastic body is protected against sand setting. The sand blasting device protecting the blind hole of the elastic body against sand setting can effectively improve the sand blasting grinding efficiency of a strain area and avoid abnormal grinding of other areas and is quite high in automation degree.

Description

technical field [0001] The invention relates to the field of sandblasting equipment, in particular to a sandblasting equipment for preventing blind holes of elastic bodies from sanding. Background technique [0002] In the load cell technology, the resistance strain gauge is pasted on the elastic element so that the other party knows that it is firmly combined as a whole. The basis is that the elastic element patch must have a surface roughness that meets the adhesion requirements, so that it can be removed. The bonding area can also activate the surface, which is conducive to the infiltration of strained adhesives. Therefore, before pasting the strain gauge, it is necessary to perform a grinding process on the bonded area of ​​the elastic strain gauge. [0003] The existing grinding process is mainly divided into two types, one is manual grinding, that is, grinding is performed manually through sandpaper. Another way is artificial sandblasting, that is, the operator holds...

AI Technical Summary

Problems solved by technology

When the strain zone of the blind hole type elastic body is polished, the blind hole is easy to accumulate sand particles, which affects the impact force of the subsequent sandblasting particles and affects the efficiency of sandblasting surface treatment
