Abstract

The invention relates to a universal force-measuring clamp for a multi-axis linkage machine tool for profile milling and a clamping method of the universal force-measuring clamp. When milling test planning is performed, especially when a five-axis machine tool is used for tests, force is difficult to measure due to the fact that no universal force-measuring clamp exists, and clamp designing is needed each time, so that test cost is increased, scientific research efficiency is improved, and equipment management difficulty is increased. The universal force-measuring clamp comprises an aligning and positioning base (7), an aligning and positioning pin (14) is mounted below the aligning and positioning base (7), and an upper plate block (1) is mounted above the aligning and positioning base (7) through a three-way force-measuring instrument (13). The universal force-measuring clamp and the clamping method are used for clamping machine tool workpieces.

Description

Be used for the general dynamometer clamp of multi-shaft interlocked lathe profile milling and clamping means thereof
Technical field:
The present invention relates to a kind of anchor clamps, be specifically related to a kind of for the general dynamometer clamp of multi-shaft interlocked lathe profile milling and clamping means thereof.
