Pneumatic numerical control shot blasting strengthen machine

Abstract

The invention discloses a numerical control shot peening strengthening machine; the shot peening chamber of the numerical control shot peening strengthening machine is provided with a numerical control rotating working platform which is controlled by CNC and is provided with two freedoms with C-direction rotation and Y-direction moving; a numerical control mechanical arm which is provided with four freedoms of B and C-direction rotation as well as X and Y-direction moving. A workpiece is clamped on the working platform; an outer wall lance is clamped by the numerical control mechanical arm to carry out shot peening strengthening on the outer surface of the workpiece. The Z-direction trailing bar of the moving mechanism of the numerical control mechanical arm is vertically provided with a dismountable inner hole lance which can carry out shot peening strengthening on the surface of the inner hole of the workpiece. Aiming at the programming processing procedure of different parts, the invention can carry out accurate and uniform shot peening strengthening processing on each shape of surface thereof. Compared with the prior art, the numerical control shot peening strengthening machine of the invention has high automatization degree and can realize precious control on the position and the angle as well as the moving speed of a spot flow and the flux of the spot. The numerical control shot peening strengthening machine of the invention solves the defect that the shot peening strengthening on the parts with complex surface shapes can not preciously control the distance between a lance and the surface of the part, the spot angle as well as the flow and the speed of the spot.

Description

technical field [0001] The invention relates to a surface shot peening strengthening treatment equipment which can significantly improve the anti-fatigue performance and stress corrosion resistance of components and prolong the service life. Background technique [0002] The shot peening machine is a device used to strengthen the surface of parts. It hits the surface of the part with a large number of high-speed moving projectiles, causing the surface layer to undergo plastic deformation and form residual compressive stress, thereby improving the fatigue resistance and stress corrosion resistance of the part. , Surface shot peening treatment equipment that prolongs its service life. [0003] Shot peening machine is mainly divided into pneumatic shot peening machine and centrifugal shot peening machine according to the way the shot is propelled. The pneumatic shot peening machine uses compressed air to push the shot to form a high-speed shot flow to strengthen the surface of ...
