Abrasive particle flow machining clamp with clamping plates convenient to replace

Abstract

The abrasive particle flow machining clamp comprises a base, a sliding rail is arranged on the top end face of the left portion of the base, a self-driven sliding seat is arranged on the sliding rail in a sliding mode, and a supporting seat is fixedly arranged on the top end face of the self-driven sliding seat; and one end of a connecting rod is fixedly arranged on the right side wall of the top of the supporting seat, and a stress disc is fixedly arranged at the other end of the connecting rod. The first elastic clamping assembly and the second elastic clamping assembly which are the same in structure and are symmetrical are arranged in the device, the first elastic clamping assembly is driven by the electric telescopic device to move in the horizontal direction, and the second elastic clamping assembly is driven by the self-driven sliding base to move in the horizontal direction; the clamping distance between the two elastic clamping assemblies is better adjusted, more types of to-be-machined workpieces can be clamped, meanwhile, clamping plates in the two elastic clamping assemblies are fastened through bolts, and assembling and disassembling are convenient.

Description

technical field [0001] The invention particularly relates to the technical field of abrasive flow processing fixtures, in particular to an abrasive grain flow processing fixture which is convenient for replacing a clamping plate. Background technique [0002] The abrasive flow equipment mainly uses the extrusion method to grind the workpiece. The abrasive used has fluidity. During the flow of the abrasive particles, it can quickly and effectively remove small holes, narrow slits, special-shaped surfaces, cavities and intersections. However, in the long-term operation process, people in the field have found that the clamping method, fixing position and performance index of the abrasive flow fixture directly affect the machining effect of the parts, especially the tubular type. It is easy to leave clip marks after metal processing, which affects its appearance, and it is relatively cumbersome to remove the clip to replace the splint. SUMMARY OF THE INVENTION [0003] To thi...

[0002] Abrasive flow equipment mainly uses the extrusion method to grind the workpiece. The abrasive used has fluidity. During the flow, the abrasive particles can quickly and effectively grind small holes, narrow slots, special-shaped surfaces, cavities and intersections. However, in the long-term operation process, those skilled in the art have found that the clamping method, fixed position and performance index of the abrasive flow fixture directly affect the processing effect of the part, especially the tubular type. It is easy to leave clamp marks after metal processing, which affects its appearance, and the clamp needs to be removed to replace the splint, which is cumbersome
