An Integral Composite Ultrasonic Knife Handle Device

Abstract

The invention discloses an integrated composite ultrasonic knife handle device which comprises a knife handle main body and a tool arranged at the front end of the knife handle main body. The knife handle main body is internally provided with a high-frequency longitudinal-torsion composite ultrasonic vibrator. A convex ring is formed on the outer circumferential face of the knife handle main body. A primary side magnetic core mounting base is rotatably arranged outside the knife handle main body and is close to the convex ring which is internally provided with a secondary side coil assembly. The primary side magnetic core mounting base is internally provided with a primary side coil assembly. The secondary side coil assembly and the primary side coil assembly are oppositely arranged. A locking power connecting plug is fixed to the outer circumferential face of the primary side magnetic core mounting base. Lead plug wires in the locking power connecting plug are separately connected with leads at the two ends of a primary side coil. The ultrasonic knife handle structure can be more conveniently mounted and used on a machine tool, meanwhile, grinding force can be effectively decreased, the service life of the tool can be effectively prolonged, and the grinding effect can be effectively improved.

Description

technical field [0001] The invention relates to the field of ultrasonic-assisted grinding, in particular to an externally rotating integral high-frequency longitudinal-torsion composite ultrasonic tool handle device. Background technique [0002] With the rapid development of industrial technology, ceramics are widely used in the fields of aerospace, automobile, communication and chemical industry because of their excellent characteristics such as high mechanical strength, wear resistance, high temperature resistance and corrosion resistance. At present, due to the characteristics of ceramic materials, their mechanical processing efficiency is low, and the processing cost caused by excessive tool wear is very high. These factors seriously restrict the promotion in the civilian field. In order to improve the processing efficiency and processing quality of ceramics, it is necessary to find a new processing method to meet the processing requirements of ceramics. [0003] Ultra...

Problems solved by technology

[0004] The existing ultrasonic tool holders are mainly installed by separating the primary coil and the secondary coil, that is, the primary coil is set on the main shaft through a collar, and the secondary coil is installed on the ultrasonic tool handle and rotates with the main shaft; The structure of the ultrasonic tool holder will occupy part of the space at the end of the spindle, and the spindle needs to be partially refitted; at the same time, the ultrasonic tool holder of this structure is often limited by the tool loading and tool changing form of the tool magazine, which affects the machine tool. Automatic tool change, inconvenient for modification and use of ordinary machine tools
