A device for automatic sandblasting of pipe seat molds for EMU braking systems

Abstract

The invention provides an automatic sand blasting device for mounting tube socket molds of a motor train unit braking system. The automatic sand blasting device comprises a box body, a sand blasting unit, a plurality of fixing devices, a first driving mechanism, a timer and a controller. The sand blasting unit comprises a sand blasting box and a second driving mechanism. The sand blasting box is arranged in a sand blasting chamber. A sand storage cavity is formed in the sand blasting box. Sand blasting heads are distributed on the periphery of the sand blasting box. The second driving mechanism is connected with the sand blasting box and drives the sand blasting box to rotate. The multiple fixing devices are arranged in the sand blasting chamber and distributed circumferentially with the sand blasting box as the center. Each fixing device comprises a workpiece fixing table which is rotatably mounted on a transverse partition plate. The first driving mechanism is fixedly connected with all the workpiece fixing tables and drives all the workpiece fixing tables to rotate. The controller is connected with the timer, the sand blasting heads, the first driving mechanism and the second driving mechanism and controls the timer, the sand blasting heads, the first driving mechanism and the second driving mechanism to act. The automatic sand blasting device is simple in structure, capable of conducting sand blasting operation on the multiple mounting tube socket molds of the motor train unit braking system, comprehensive in sand blasting and high in sand blasting quality.

Description

Technical field [0001] The invention relates to the technical field of sandblasting equipment, in particular to an automatic sandblasting device for mounting pipe seat molds of the brake system of an EMU. Background technique [0002] Sandblasting machine is a kind of mechanical equipment that can make abrasives spray on the surface of the workpiece by means of compressed air power. The abrasive is sprayed at high speed to the surface of the workpiece to be processed for impact grinding, which changes the shape or shape of the outer surface of the workpiece. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness It improves the mechanical properties of the surface of the workpiece, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating film, and also conducive to ...

AI Technical Summary

Problems solved by technology

During the sandblasting process of the sandblasting machine for installing the pipe seat mold casting of the existing EMU brake system, there will be incomplete sandblasting of the details, resulting in low sandblasting quality, increasing the chance of rework, and low work efficiency
