Sand blasting device

Abstract

The invention discloses a sand blasting device. The sand blasting device comprises a box body, a sand blasting machine body and a cross board, the two ends of the cross board are slidably connected with the left side wall and the right side wall of the box body respectively, the sand blasting machine body is fixedly connected to the cross board, a walking mechanism is arranged on the lower end ofthe box body, a fixing block is fixedly connected with the bottom of the interior of the box body, the upper end of the fixing block is provided with a first groove, the left side wall and the right side wall of the first groove are provided with second grooves respectively, a movable rod penetrates through the bottoms of the second grooves, a fixing board is fixedly connected with the end, closeto the first groove, of the movable rod, a plurality of connection blocks are arranged on the side walls of the interiors of the second grooves, limiting grooves are arranged on the opposite side walls of the plurality of connection blocks, a plurality of limiting blocks matched with the limiting grooves are arranged on the movable rod, the parts, located in the second grooves, of the movable rodare sleeved with springs, and an adjusting mechanism used for adjusting the cross board is arranged on the right side wall of the box body. The sand blasting device can adjust the sand blasting machine body, can limit to-be-processed pieces, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a sand blasting device. Background technique [0002] The process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material to the surface of the workpiece to be processed at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece The surface has a certain degree of cleanliness and different roughness, which improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, and prolonging the durability of the coating film. It is also conducive to the leveling and decoration of pai...

AI Technical Summary

Problems solved by technology

In the prior art, the fixation effect on the workpiece is not good, resulting in uneven sandblasting and different shades after sandblasting, which affects the appearance of the workpiece; and the position of the sandblasting machine in the prior art is fixed, and the required appearance is formed It is more difficult; and the workpiece is a cylindrical object. If the rotating shaft does not rotate, there will be dead angles, resulting in some surfaces that cannot be sprayed.
