Abstract

The invention discloses a numerical control rotary table. The numerical control rotary table comprises a connection plate arranged on a guide rail of a machine tool, a gear box is fixed on the connection plate, a motor is arranged on one side of the gear box, and an output shaft of the motor is in the horizontal direction and penetrates through a side wall of the gear box to enter an inner cavity of the gear box and to be connected with a worm gear and a worm; the output shaft drives the worm to rotate, the worm gear drives a reduction gear unit to rotate, the reduction gear unit comprises a driving gear and a driven gear, the axis of the drive gear is perpendicular to the horizontal surface, a working table supporting body is fixed at the upper end of the driven gear, and a working table is fixed above the working table supporting body; a locking mechanism is arranged in the middle of the driven gear in a penetration manner and comprises an upper hirth coupling fixed at the bottom end of the working table supporting body and a lower hirth coupling fixed on a hydraulic cylinder, and the working table supporting body can move up and down under pushing of a piston shaft of the hydraulic cylinder. The numerical control rotary table is high in precision and reliability.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a numerical control rotary workbench. Background technique [0002] CNC rotary table is a common component of CNC milling machine, often used as a servo axis of CNC milling machine, that is, the C axis of vertical CNC milling machine and the B axis of horizontal CNC milling machine. The CNC rotary table is suitable for continuous rotary processing and multi-face processing of plate and box workpieces, controlled by a CNC system. [0003] The existing CNC rotary table has low precision and low reliability, and the rotary table used in hard rail and line rail machine tools is greatly restricted by the structure of the guide rail. [0004] Therefore, designing a new type of CNC rotary table with high precision and high reliability is a technical problem to be solved in this field. Contents of the invention [0005] The technical problem to be solved by the present ...
