Abstract

The invention discloses a heavy load straight tooth transmission full-closed loop high precision rotating table. The rotating table comprises a left servo motor and deceleration system (1), a floating type hydraulic disc brake (2), a left straight tooth transmission shaft (3), a plane slide rail (4), a main shaft support system (5), a base (6), a working table (7), a right straight tooth transmission shaft (8), a right servo motor and deceleration system (9), a cylindrical roller support (10) and a grating ruler feedback mechanism (12), wherein the driving device adopts double-straight tooth bio-directional anti-backlash transmission; the support system adopts multiple auxiliary support; the brake device adopts a hydraulic disc brake device; a grating ruler is adopted for angle feedback; a full-closed loop control system is achieved. The rotating table has the advantages of being accurate in positioning, high in bearing capacity, long in service life, and the like.

Description

technical field [0001] The invention relates to a special equipment for indexing, especially capable of meeting the high-precision requirements of indexing for processing large workpieces. Background technique [0002] At present, the structure of the known rotary table includes a base, a rotary table, a worm gear transmission mechanism, and a main shaft support mechanism. The electrical system does not have a feedback adjustment system or a semi-closed loop feedback adjustment system. The table rotates, and the table is indexed by controlling the number of rotations of the servo motor. Semi-closed-loop system, the grating scale is installed on the main shaft for angular position feedback. However, due to the transmission characteristics of the worm gear itself, there are many defects in the workbench. For example, the low efficiency of the worm gear and worm drive results in low load capacity of the turntable, serious wear of the worm gear and worm, which causes tooth surf...
