Height-adjustable workbench for five-axis machine tool

Abstract

The invention relates to a height-adjustable workbench for a five-axis machine tool, comprising a base, an intermediate platform and a workbench arranged separately from bottom to top; multiple supports are detachably installed between the base and the intermediate platform Columns, the plurality of support columns are distributed symmetrically around the center of the base; there are multiple guide rods distributed symmetrically around the center of the intermediate platform between the intermediate platform and the worktable, and the intermediate platform is provided with the guide rods The matching guide hole, the upper end of the guide rod is firmly connected with the workbench, and the lower end is slidably matched with the guide hole and locked by the lock nut; the center position of the workbench is rotated with a screw rod, and the center position of the middle table is fixedly installed There is a nut, and the screw rod is screwed in cooperation with the nut.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a five-axis machine tool. Background technique [0002] In recent years, the use of five-axis machine tools has been increasing. However, after the swing angle of the spindle of the five-axis machine tool or the swing angle of the rotary table, if the workpiece cannot be installed at a certain height from the work table, the machine tool spindle will collide with the work table, and the installation height of different workpieces is different. , causing the machine tool to be equipped with many kinds of fixtures. [0003] At present, the common practice of enterprises for workbench heightening is to design an independent heightening fixture for each part. The design cycle and manufacturing cycle are very long, and the cost is also high. SUMMARY OF THE INVENTION [0004] In view of the above-mentioned problems existing in the existing five-axis machine tools, the applican...

Problems solved by technology

[0002] In recent years, the use of five-axis machine tools is increasing: but after the swing angle of the spindle of the five-axis machine tool or the swing angle of the rotary table, if the workpiece cannot be installed at a certain height from the worktable, the machine tool spindle will collide with the worktable, and the installation height of different workpieces is different. , causing the machine tool to be equipped with many kinds of fixtures

[0003] At present, the common way for enterprises to raise the workbench is to design an independent heightening fixture for each part. The design cycle and manufacturing cycle are very long, and the cost is also high.
