A Flexible Fixture with Active Control for Clamping Complex Components

Abstract

The invention discloses a flexible clamp for active control of complex component clamping, which includes a clamp main body, a data measurement module, a flexible clamping module and a power drive module; the clamp main body is composed of a lower clamp body, an upper clamp body and mounting bolts, The corresponding displacements of the edges of the lower clamp body and the upper clamp body are provided with round holes, and the mounting bolts pass through the round holes on the lower clamp body and the upper clamp body to fasten the lower clamp body and the upper clamp body together. The upper clamp body is provided with a through hole, and the upper clamp body is provided with a number of through grooves, and the through grooves are centered symmetrically around the upper clamp body; the data measurement module is composed of a force sensor, a data processor and a computer. , the data processor is electrically connected to the force sensor and the computer respectively.

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, redu...

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
