Problems solved by technology

However, due to the lifting action of the gear plate on the multi-tooth indexing table, the beam loss is caused, which makes the measurement unstable or even fails, which is the main defect of this measurement method

Embodiment Construction

[0024] See Figure 4 , the lower toothed plate 1 is fixed to the base 5, the upper toothed plate 2 is fixed to the inner ring of the circular diaphragm 8 through the connecting body 9, the outer ring of the circular diaphragm 8 is connected to the table 10, and the ball 7 is two rings distributed On the upper and lower sides of the table 10, it is limited by the base 5 and the limit plate 6 fixed on the base 5. The laser target mirror 23 is installed on the table 10, and the fixed plate 12 is fixed on the base 5, so as to work with the CNC rotary station connection. After the circular diaphragm 8 is connected with the connecting body 9 and the table top 10, it has high rigidity in the tangential direction of the circumference, so the connecting body 9 and the table top 10 can be regarded as a rigid connection.

[0025] Before the measurement, install the multi-tooth indexing table mechanism with a non-lifting plate on the center of the CNC rotary table, and install the laser ...

Abstract

The invention relates to a multi-tooth indexing table device without lifting a table-board, which solves the problem of unstable measurement caused by the lifting of the table-board in the prior device. A lower fluted disc (1) is fixedly connected with a pedestal (5); the lower end of an upper fluted disc (2) is engaged with the lower fluted disc (1); the pedestal (5) is provided with an axial lifting device (14) and a horizontal circumferential transmission device (4) which are in transmission connection with the lower fluted disc (1); the upper fluted disc (2) is connected with the coaxial table-board (10) through a membrane (8); the table-board (10) is rotatably matched with the pedestal (5); and a target mirror (23) is positioned in the axle centre of the table-board (10) and is fixedly connected with the table-board.

Description

Technical field: [0001] The invention relates to a high-precision angle measuring device, in particular to a large-angle measuring device combined with a laser angle interferometer and a multi-tooth indexing platform. Background technique: [0002] Using the combination of high-precision multi-tooth indexing table and laser angle interferometer, the positioning accuracy of the CNC rotary table can be measured with high precision. At present, due to the lifting and lowering of the multi-tooth indexing table on which the laser target mirror is installed, the foreign advanced mainstream laser measuring instruments of this type cause serious loss of laser light intensity, resulting in unstable measurement or even interruption of measurement. In order to solve this problem, the present invention invents a multi-tooth indexing table measuring device that does not move up and down, which better solves the problem of accuracy and reliability of the laser angle interferometer for mea...
