Abstract

The invention provides a vertical axis counterweight device for a complex curve multi-axis linkage processing machine tool and relates to a counterweight device for the complex curve multi-axis linkage processing machine tool. The counterweight device is used for solving the problems of limited bearing capacity and barycentre deviation of a linear motor platform or ball-screw guide rail applied to a vertical axis of the complex curve multi-axis linkage processing machine tool. A big counterweight block is connected to two small counterweight blocks; the big counterweight block is connected toa hanging ring bolt; a flange linear bearing is arranged in each bearing through hole of the big counterweight block; a principal axis is arranged in inner holes of each two flange linear bearings; the flange linear bearings are in sliding fit with the principal axis; each principal axis is connected to two principal axis supporting bases; a limiting spring is sleeved on each principal axis; two supporting axes are vertically arranged between two guide wheel connecting plates; each of the supporting axes is connected to two guide wheel connecting plates; each guide wheel is connected to each of the supporting axes through axle-hole fitting; and two ends of a rope are connected to the hanging ring bolt and a load. The vertical axis counterweight device is applied to the complex curve multi-axis linkage processing machine tool.

Description

technical field [0001] The invention relates to a counterweight device of a complex curved surface multi-axis linkage processing machine tool. Background technique [0002] With the rapid development of modern science and technology, many cutting-edge equipment require high-precision parts with various typical structures and complex surfaces. Surface repair of micro-defects and other complex surface parts require three-axis or five-axis linkage precision ultra-precision machine tools to realize their processing. In the development process of multi-axis linkage processing machine tools for complex curved surfaces, most of them adopt a five-axis linkage processing system consisting of three linear movement axes and two rotation axes. One of the three linear axes is a vertical axis, and the vertical axis This can be done with a linear motor stage or a ball screw guide. When designing a machine tool, it is necessary to install a rotating motor and a micro-milling tool spindle ...
