Embodiment Construction

[0018] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0019] This embodiment is composed of inner wedge ring 5 , outer wedge ring 4 , steel ball 6 , pressure plate 1 , cage 7 and flange sleeve 3 . The outer wedge ring 4 can rotate 5 with the table body 2 relative to the inner wedge ring, and the outer periphery of the inner wedge ring 5 and the inner periphery of the outer wedge ring 4 are respectively provided with grooves that can be opposed to each other. Pressing plate 1 is arranged on the upper side of steel ball 6, and pressing plate 1 can press steel ball 6 in the groove of inner and outer wedge rings 5,4 so that inner and outer wedge rings 5,4 are relatively positioned. The cage 7 is fixed on the platen 1 . The cage 7 is provided with a flange sleeve 3, and the steel ball 6 is placed in the flange sleeve 3.

[0020] In order to make the steel ball 6 move along with it in the flange sleeve 3 ...

Abstract

The invention is about a rotary table and a rotary indexing location device which includes the inner wedge ring, the external wedge ring, the steel ball, the pressure plate and the retainer. The external wedge ring can rotate to the inner wedge ring with the rotary table andthe external peripheral of the internal wedge ring and the inner peripheral of the external wedge ring are installed respectively with the flutes which can involution in opposite direction; the steel ball can be pressed in the flute to locate the inner and the external wedge rings; the flange cover is installed in the retainer and the steel ball is put in it. It can decrease the wearing of the external / inner wedge ring and improve the location accuracy and retentivity of the rotary table; also it does not have the noise of 'Kada Kada' when it rotates.

Description

technical field [0001] The invention relates to a rotary table used in a rotary multi-station machine tool, in particular to a rotary indexing and positioning mechanism of the rotary table. Background technique [0002] The rotary table is an indexing device for rotary multi-station machine tools. When working, the workpiece is installed on the worktable through the fixture to achieve rotary indexing and positioning, so that the processing parts of each station of the machine tool can complete the processing procedures of each surface of the workpiece at high speed, stably and accurately. The workbench rotates once to complete the different processing procedures of the workpiece on the machine tool. The application of the rotary table has the advantages of high production efficiency, high degree of automation, saving loading and unloading time, saving labor, and small floor space. It is widely used in machine tools and production lines of industrial enterprises. [0003] T...
