Multifunctional sand blasting device for machining high speed train cast aluminum gear box die

Abstract

The invention provides a multifunctional sand blasting device for machining a high speed train cast aluminum gear box die. The multifunctional sand blasting device comprises a base, a cover body, a clamping mechanism and a sand blasting mechanism. The clamping mechanism comprises a first rotary disc, a second rotary disc, a first drive mechanism, a second drive mechanism and multiple clamping devices. The first drive mechanism is connected with the first rotary disc and drives the first rotary disc to rotate. The second drive mechanism is connected with the second rotary disc and drives the second rotary disc to rotate. The multiple clamping devices are circumferentially distributed with the central axis of the first rotary disc as the central axis. The two ends of each clamping device are connected with the first rotary disc and the second rotary disc correspondingly. The sand blasting mechanism comprises an installation frame, a third drive mechanism, and multiple sand blasting devices used for conducting sand blasting on to-be-machined workpieces. The installation frame is connected with the third drive mechanism and is driven by the third drive mechanism to vertically move in the vertical direction, and the multiple sand blasting device are arranged on the installation frame at intervals. According to the multifunctional sand blasting device, continuous sand blasting can be achieved on the high speed train cast aluminum gear box die under the cooperation of the clamping mechanism and the sand blasting mechanism.

Description

Technical field [0001] The invention relates to the technical field of sandblasting equipment, in particular to a sandblasting equipment for processing a multifunctional high-speed train cast aluminum gearbox mold. 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 can improve 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 ...
