A new test jig for shot peening cleaning of thin plates

Abstract

The invention relates to a new type of thin plate shot blasting cleaning fixture for testing, which includes a long groove, a clamp block, a specimen groove, a long bolt, a clamping nut, an angle gauge plate, a pin shaft and a rotating bottom plate, and two side walls on the long groove There is a through hole on the clamp block, the long groove and the clamp block are connected by long bolts, a rectangular groove with a certain depth is arranged in the middle of the specimen groove, and is fixed on the long groove, and the clamping nut is matched with the long bolt; the angle There are 9 through holes evenly distributed on the instrument panel, and there are light holes with a certain depth on both sides of the rotating bottom plate; the angle instrument panel and the rotating bottom plate are connected by pin shafts. The invention has the advantages of simple structure, convenient installation and use, and the use of the angle instrument panel and the rotating bottom plate will make the adjustment of the angle in the test process more convenient and quick.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a novel thin-plate shot-blasting fixture for testing. Background technique [0002] Shot peening is to spray high-speed projectiles onto the surface of the workpiece to cause plastic deformation on the surface of the workpiece and form a strengthening layer with a certain thickness. It is one of the effective methods to improve the fatigue life of parts. Shot peening can also use the impact and friction of iron shot Function, remove rust and other pollution on the metal surface, and get a certain roughness, revealing the true color of the metal. The angle between the nozzle and the test piece has a certain influence on the surface roughness of the test piece after shot peening. In order to obtain a surface with different roughness, it is necessary to adjust the angle between the nozzle and the test piece during the shot peening process. Adjustment, the current m...

Problems solved by technology

The angle between the nozzle and the test piece has a certain influence on the surface roughness of the test piece after shot peening. In order to obtain a surface with different roughness, it is necessary to adjust the angle between the nozzle and the test piece during the shot peening process. Adjustment, the current method of adjusting the required angle is obtained by adjusting the inclination of the nozzle. The process needs to loosen the nut and then tighten the nut. The process is cumbersome and easy to damage, so that the nozzle will loosen due to the relatively large jet reaction force during the working process. , therefore, it is extremely important to obtain the required angle between the nozzle and the specimen by adjusting the angle of the specimen. The design of a new test thin plate shot peening fixture will solve the above problems well.
