Rotary table

Abstract

In order to solve the problems that an ordinary rotary table is large in indexing error and inaccurate in zeroing position, the rotary table is provided, accurate positioning is achieved through cooperation of a travel switch, a pinion assembly and a rotary gear ring, after the travel switch is turned on, the table top of the rotary table floats, and the rotary gear ring is turned off. After the small gear assembly and the rotary gear ring are engaged and disengaged and the workbench is rotated to a corresponding angle, the switch is closed in the opposite direction, the small gear assembly and the rotary gear ring are matched and are in a normal machining state, the rotary workbench is high in positioning precision, and due to the fact that the workbench is made of a magnet, a pressing device does not need to be additionally arranged, and the machining efficiency is improved. And a workpiece processed at the upper part is very convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the field of mold base processing, and more particularly, to a rotary table. Background technique [0002] Now with the continuous progress of the industrial society, the processing technology is also constantly improving, and the processing accuracy is getting higher and higher. The ordinary rotary table cannot meet the increasing processing accuracy due to its large indexing error and inaccurate zeroing position. Nowadays, various machine tools and various processing equipment are increasingly emphasizing the collaborative work between the processing end and the workbench. [0003] As the name suggests, the rotary table is a rotatable work platform, which is used in various fields. In machining, the rotary table is indispensable. Machine tool accessories that realize rotation and indexing positioning, especially suitable for turning and milling compound machining machine tools where both tools and workpieces can be rotated. ...

Problems solved by technology

[0004] In order to solve the problem of large indexing error and inaccurate zeroing position of the ordinary rotary table, the present invention proposes a rotary table, which is realized by the cooperation of the travel switch 8, the pinion assembly 5 and the rotary ring gear 9. Accurate positioning, after the limit switch 8 is turned on, the surface of the worktable 3 floats, the pinion assembly 5 and the rotary ring gear 9 are disengaged, and then the worktable 3 is rotated to the corresponding angle, the switch is closed in the opposite direction, and the pinion assembly 5 coincides with the rotary ring gear 9, and is in a normal processing state. The positioning accuracy of the rotary table is high, and because the table 3 is made of magnet material, there is no need to add a pressing device, which is very convenient for disassembling and assembling the upper processed workpiece
