Anti-deformation flexible clamp for processing curved surface thin-walled parts and its clamping method

Abstract

The invention discloses an anti-deformation flexible fixture for processing curved surface thin-walled parts and a clamping method thereof. The invention uses floating rods to carry out floating support for the workpiece, so that the vacuum suction cup device can be adaptively attached to the surface of the workpiece under the action of a compression spring , and then use the hydraulic tensioning sleeve to lock and fix the auxiliary support rod and the support bottom column, and the positioning and clamping of the workpiece can be realized. The invention can greatly improve the clamping efficiency and save clamping time. For the processing of most curved thin-walled workpieces, the fixture can be positioned at any point in the space area, and a corresponding positioning template is designed for each thin-walled workpiece, so that the parts can be quickly positioned and the workpiece can be quickly replaced. , The clamping scheme uses a vacuum suction cup device for clamping, which is convenient and stable without affecting the surface processing quality, and the position of the auxiliary support point of the clamping point is reasonably arranged to ensure that the workpiece does not shift and deform during processing.

Description

technical field [0001] The invention belongs to the technical field of fixtures, in particular to a flexible anti-deformation fixture for processing curved surface thin-walled parts of an automobile main model. Background technique [0002] Curved thin-walled parts are now more and more widely used in our industrial manufacturing industry. Most of the lines of the main car model adopt curved surface streamlined design. Curved thin-walled parts are easily deformed during the cutting process. If appropriate auxiliary supports are not used, it is difficult to guarantee the machining accuracy and quality of the parts. How to improve the machining accuracy of curved thin-walled parts has become the concern of most manufacturing companies. question. At present, curved thin-walled parts are generally processed by five-axis CNC machine tools, so it is necessary to optimize the clamping and auxiliary support of the workpiece to effectively prevent deformation of curved thin-walled p...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a flexible clamp for anti-deformation processing of curved surface thin-walled parts to solve the problem of long production time of existing clamps, time-consuming and laborious installation of each clamp, and poor support rigidity. The effect is not good and it is harmful to health when cleaning. When finding the position of the support point and the clamping point, it is determined by experience, and the accuracy cannot be controlled.
