A spray gun fixture for shot peening of wing panels

Abstract

The invention relates to a spray gun fixture used for shot peening processing of wing wall panels, comprising a block, a support arm, a long strip groove arranged on the support arm, and a cylinder body fitted on the support arm. The two opposite sides of the cylinder are respectively provided with sliding grooves, and two sliding blocks corresponding to the two sliding grooves are fixedly connected to the cylinder body; A pin shaft is arranged in the cylinder body, a stopper is arranged in the middle of the pin shaft, and a compression spring is arranged between the end cover and the stopper; one end of the block close to the cylinder body is provided with a strip-shaped long groove A matching limiting portion is provided on the limiting portion with a recess matched with the pin shaft, and an end of the block away from the long strip groove is provided with a mounting portion for fixing the spray gun. The invention can simply and conveniently replace the spray gun, thereby improving the production efficiency of the special spray gun fixture used for shot blasting the wing wall plate and reducing the production cost.

Description

technical field [0001] The invention relates to a spray gun fixture used for shot peening processing of wing wall panels, belonging to the technical field of surface treatment. Background technique [0002] The shot peening process can be used to strengthen or shape the surface of the wing panel, improve its lifting performance, improve fuel consumption and reduce environmental pollution. The shot-peened wing will increase the ability to resist bending fatigue, and the shot-peened side will deform in the elastic range under the action of residual extrusion stress, resulting in residual extrusion stress, which can resist corrosion cracking and fatigue of parts. [0003] When the wing panel is processed by the shot peening process, it is necessary to use a variety of different spray guns, such as four-point spray guns, deep hole groove spray guns, rotating reflection spray guns, etc., so the process requires that the spray guns can be quickly replaced. In the prior art, the s...

AI Technical Summary

Problems solved by technology

[0004] 1) When replacing the spray gun, the shot blasting machine must be shut down, which affects the production efficiency

[0005] 2) During the shot peening process of bolts or pins, the shot material will rebound to the bolts or pins. Under strong force, the bolts or pins are easily deformed, making it difficult to disassemble

[0006] 3) For a given piece to be processed, the installation angle and position of each spray gun is often determined in advance, and different spray guns have different installation angles relative to the workpiece; but when replacing the spray gun, wait for the bolts or pins to be removed Finally, when installing the spray gun to be replaced again, because different spray guns have different installation angles relative to the workpiece to be processed, it is not easy to determine the accurate installation angle and position of the spray gun

Just for this reason, in the prior art, the spray gun and the frame are pre-installed and replaced together with the frame, which will result in higher cost and larger weight, which will bring a lot of trouble to the replacement work. Difficult; in addition, it reduces the efficiency of the spray gun
