Liquid dipping numerical control turning table

Abstract

The invention discloses a liquid-immersible numerical control turntable. The turntable includes a turntable seat, a rotating shaft, a pressure ring, a turntable support ring, a servo motor and an O-shaped sealing ring. The rotating shaft of the turntable is arranged at the center of the turntable, the turntable seat is fixedly arranged on the turntable support ring, and the motor seat is fixedly arranged on the turntable seat. The servo motor is fixed on the motor seat, the motor shaft is connected with the rotating shaft through a coupling, and the rotating shaft is supported by a bearing arranged in the turntable seat and driven to rotate by the servo motor. The present invention realizes the dynamic and static sealing of the gap between the parts in the turntable by setting the sealing ring, and arranges the annular groove and the liquid discharge joint on the turntable seat, which can better meet the requirements of sealing the rotating parts in various liquid environments. High performance, high precision and reliable operation. The invention has simple manufacturing process, short transmission chain and good protection performance.

Description

technical field [0001] The invention belongs to the field of work manipulation turntables or turntables specially combined with, configured with, or dedicated to machine tools, and in particular relates to a liquid-immersible numerically controlled turntable. Background technique [0002] In the fields of machinery manufacturing and precision testing, some rotating devices that can work in liquid environments are often required, such as cutting fluid environments for machining, water environments for ultrasonic testing, etc., which require the devices to have good sealing performance. If the protection is not in place, it will cause damage to mechanical parts and motors. [0003] Most of the structure of CNC liquid immersion turntable products is a structure that uses a servo motor to transmit power from the top of the liquid surface to the bottom of the liquid surface through a worm gear, worm or synchronous belt to drive the turntable to rotate. The manufacturing process ...

AI Technical Summary

Problems solved by technology

The manufacturing process of this kind of CNC turntable is complex and requires a high level of manufacturing

At present, the level of this kind of products is quite different, the reason is the difference in manufacturing capacity and level, the most critical is the difficulty of manufacturing key components such as worm gears, worms, synchronous pulleys and complex technology; on the other hand, due to the Long, the transmission accuracy of the turntable is greatly affected by the manufacturing accuracy of the key transmission parts, and the accuracy is difficult to improve
