A mechanical torsional vibration table based on synchronous pulley

Abstract

The invention discloses a mechanical torsional vibration table based on synchronous pulleys. The mechanical torsional vibration table is characterized by comprising a torsional vibration table support, a torsional vibration platform and a torsional vibration generator. The torsional vibration table is novel in design and reasonable in layout. A servo motor controls a driving synchronous pulley torotate, through transmission by a synchronous belt, driven synchronous pulleys are indirectly driven to rotate so as to drive an eccentric balance weight to rotate, the torsional vibration platform and a workpiece are made to vibrate, and when the torsional vibration table works, the vibrating frequency and vibrating amplitude can be adjusted by adjusting the rotating speed of the servo motor andthe gravity center position of the eccentric balance weight structure. The torsional vibration table has the advantages of being simple in structure, easy to achieve, convenient to operate, low in manufacturing and implementing cost, and high in universality, and is suitable for being popularized for use.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a mechanical torsional vibration table based on a synchronous pulley. Background technique [0002] In mechanical processing, such as turning, drilling, grinding, etc., axial vibration or torsional vibration of a certain frequency and amplitude is applied to the tool or the workpiece to be processed, which is beneficial to reduce cutting force and cutting heat, and reduce the risk of sticking and chipping. According to the situation, it can improve the processing efficiency and prolong the tool life. According to the frequency of superimposed vibration, this technology can be divided into ultrasonic vibration assisted processing and non-ultrasonic vibration assisted processing. For some special materials, such as carbon fiber boards, glass fiber boards, etc., during the drilling and reaming process, because the fiber material inside is easy to be pulled ...

AI Technical Summary

Problems solved by technology

For some special materials, such as carbon fiber boards, glass fiber boards, etc., during the drilling and reaming process, because the fiber material inside is easy to be pulled apart and broken during processing, the processing effect is poor, or even impossible to process. The axial ultrasonic or non-ultrasonic torsional vibration of the drill bit or the workpiece can make the cutting force change periodically, promote the cutting of the fiber material, prevent it from being pulled out, and improve the processing effect, but the market is suitable for fiber material drilling. There are not many mechanical torsional vibration tables

[0003] For example, "A Composite Vibration Drilling Device" with patent number CN201610002983.1 superimposes ultrasonic frequency torsional vibration on the drill bit. Its technical purpose is to satisfy non-metal hard and brittle materials and difficult-to-cut metal materials, but the drilling spindle The production, production, installation and maintenance requirements are relatively high
