Sand blasting device for processing of cast aluminium gear case mold of high-speed train

Abstract

The invention provides a sand blasting device for processing of a cast aluminium gear case mold of a high-speed train. The sand blasting device comprises a base, a sand blasting hood, a rotary disc, a first driving mechanism, a plurality of vertical sand blasting components, a plurality of horizontal sand blasting components, a plurality of second driving mechanisms, a timing device and a control device, wherein the sand blasting hood is arranged on the base; the rotary disc is arranged inside the sand blasting hood and is parallel to the base; a plurality of mounting seats used for fixing to-be-processed workpieces, are arranged on the side, away from the base, of the rotary disc; the first driving mechanism is used for driving the rotary disc to rotate; the second driving mechanisms are used for driving the mounting seats to rotate; the plurality of vertical sand blasting components are positioned above the rotary disc and are mounted at the top end of the inner side of the sand blasting hood; the number of the plurality of horizontal sand blasting components is the same as the number of the mounting seats; the horizontal sand blasting components and the mounting seats are in one-to-one correspondence; and the control device is connected with the first driving mechanism, the plurality of vertical sand blasting components, the plurality of horizontal sand blasting components, the plurality of second driving mechanisms and the timing device. According to the sand blasting device, the sand blasting is comprehensive, the sand blasting quality is high, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of sandblasting equipment, in particular to a sandblasting device for processing molds of cast aluminum gearboxes for high-speed trains. Background technique [0002] Sandblasting machine is a kind of mechanical equipment that can spray abrasives onto the surface of workpieces by means of compressed air power. The abrasive is sprayed at high speed to the surface of the workpiece to be treated for impact grinding, so that the shape 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 obtains a certain degree of cleanliness and different roughness The degree improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and is also cond...
