Complex component clamping active control flexible clamp

Abstract

The invention discloses a complex component clamping active control flexible clamp which comprises a clamp body, a data measuring module, a flexible clamping module and a power driving module. The clamp body is composed of a lower clamp body, an upper clamp body and an installing bolt, corresponding displacement of the edges of the lower clamp body and the upper clamp body are provided with roundholes, the installing bolt penetrates the round holes in the lower clamp body and the upper clamp body to fasten the lower clamp body and the upper clamp body together, a through hole is formed in theupper clamp body, a plurality of through holes are formed in the upper clamp body, and the through grooves are distributed in a central symmetry manner with the upper clamp body as the center; and the data measuring module is composed of a force sensor, a data processor and a computer, and the data processor is electrically connected with the force sensor and the computer.

Description

technical field [0001] The invention relates to the technical fields of aerospace, automobiles, etc., and specifically relates to a flexible clamp for active control of complex component clamping. Background technique [0002] During the workpiece processing, the clamping force of the traditional fixture clamping the workpiece is random and judged by the experience of the operator. In order to ensure the clamping of the workpiece, the actual clamping force is often much greater than the theoretically required clamping force. This results in a large clamping force not only causing additional load on the workpiece but also causing unnecessary deformation of the workpiece, affecting machining accuracy. Secondly, for complex parts, the fixture structure used in the traditional clamping scheme is relatively cumbersome, and the design and manufacturing costs are relatively high. A combination of different fixtures is usually used, and the adjustment process takes a long time, re...

AI Technical Summary

Problems solved by technology

[0008] 1. The accuracy, efficiency and controllability of widely used traditional fixtures are low;

[0009] 2. The adjustment of the clamping force of the traditional fixture depends on the experience of the workers rather than the theory;

[0010] 3. Crucial tool movement parameters are ignored, and the clamping force of the fixture with sensors is difficult or invalid to change
