A shot peening fixture for thin-walled parts

Abstract

The invention discloses a shot blasting clamp used for thin-wall class parts. The shot blasting clamp comprises a bottom box and a middle box, the upper end of the bottom box is connected with the middle box through a sliding rail, the upper end of the middle box is provided with a table top frame, one side of the table top frame is connected with the edge of the middle box through a hinge, a jacking device is hinged between the bottom face of the other side of the table top frame and the bottom face of the middle box, and a rack is arranged on the bottom face of the middle box; a gear is arranged in the bottom box to be meshed with the rack, the gear is connected with a driving shaft, the driving shaft is connected with a driving motor, a clamping frame capable of overturning is arrangedin the table top frame, dual-direction lead screws are arranged at the four edges of the clamping frame, each dual-direction lead screw is provided with two sliding blocks, an adjusting rod is hingedto each sliding block, and the ends of the adjusting rods are hinged and connected with clamping blocks used for clamping the outer walls of frame parts; and one side of the table top frame is provided with a positioning bolt used for fixing the clamping frame. By means of the shot blasting clamp, different-angle shot blasting treatment on the frame parts can be achieved, even shot blasting treatment is carried out on the thin-wall class parts, operation is quick, and the shot blasting efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of shot peening processing equipment, in particular to a shot peening fixture for thin-walled parts. Background technique [0002] With the rapid development of the aviation industry and the extensive use of aluminum alloy thin-walled parts in aircraft, the aerospace industry has put forward higher requirements for the fatigue resistance and dimensional stability of aluminum alloy thin-walled components. Shot blasting is often used in production to improve the performance of parts. However, due to the diversity and complexity of aerospace thin-walled components, how to achieve the universality requirements of fixtures is an important technical problem that needs to be solved. Secondly, how to carry out uniform shot peening at different angles on thin-walled parts is also an important technical problem to be solved. Judging from the current research status, the sandblasting technology for aerospace aluminum ...
