Clamping method and clamping device for irregular non-metal workpiece

Abstract

The invention discloses a clamping method and a clamping device for an irregular non-metal workpiece. A T-shaped groove workbench of a positioning mechanism of the irregular non-metal workpiece to be processed is arranged on the bottom surface of a cooling groove; and a condensing pipe and a heating pipe are arranged on the four inner side faces of the cooling groove respectively and are connected with a refrigerating device and a heating device respectively. The method comprises the following steps of: positioning the irregular non-metal workpiece to be processed on the positioning mechanism and fixing the irregular non-metal workpiece and the positioning mechanism together on the bottom surface of the cooling groove; filling water into the cooling groove; starting the refrigerating device, condensing the water in the cooling groove into ice through the condensing pipe, and clamping the workpiece; and after processing the cooling groove in which the workpiece is clamped on a processing machine tool, starting the heating device, melting the ice in the cooling groove into water through the heating pipe and then taking the workpiece out. The clamping method is simple in operation and reliable in clamping effect and can ensure uniform clamping force applied to the workpiece so as to effectively ensure the processing precision.

Description

Technical field [0001] The invention relates to a clamping method and device for a workpiece, in particular to a clamping method and a clamping device for irregular non-metallic workpieces. Background technique [0002] Fixtures, also known as fixtures, are devices used to fix processed objects in the mechanical manufacturing process to keep them in the correct position for processing or testing. Broadly speaking, in any process in the process, the device used to quickly, conveniently and safely install the workpiece can be called a fixture. [0003] Traditional fixtures in machining are mainly divided into mechanical fixtures and electromagnetic fixtures. Among them, mechanical clamps use clamping mechanisms (such as spiral clamping mechanism, oblique wedge clamping mechanism, eccentric clamping mechanism, linkage clamping mechanism and centering clamping mechanism, etc.) to clamp the workpiece. Its advantages are simple operation and clamping The tight force is large, the disad...

AI Technical Summary

Problems solved by technology

For workpieces made of these materials, due to various factors such as non-ferromagnetic materials, complexity of part shape, strength, stiffness, etc., conventional clamping methods and devices cannot complete the clamping operation during part processing or measurement. Therefore, There is a need for a clamping method and device for such irregular non-metallic workpieces, which require uniform clamping force and easy operation during the clamping process.
