A Tool Holder Shrinking System Based on Electromagnetic Induction

Abstract

The invention provides a cutter heating and assembling system based on electromagnetic induction. The cutter heating and assembling system comprises an induction heating coil, a touch display unit and a control mainboard, wherein the induction heating coil is used for carrying out electromagnetic induction heating on cutter handles in the coil; default heating parameters corresponding to the cutter handles with different diameters of different manufacturers are stored in the touch display unit; the touch display unit is used for transmitting heating parameters input by users to the control mainboard in a serial port communication manner and simultaneously displaying diameters, electrifying frequency and heating time of the heated cutter handles; the control mainboard is used for electrifying the induction heating coil and simultaneously setting electrifying frequency and electrifying time of the induction heating coil according to the heating parameters provided by the touch display unit. The system is clear in circuit structure principle; through early emulation analysis and later many experiments of the coil, the cutter handles are optimally heated and damaged; all functional units adopted by the system are easy to implement; the time for heating and assembly different cutters or replacing different cutters lasts for just 3-15 seconds.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an electromagnetic induction-based heat-fitting system for tool holders. Background technique [0002] Induction heating technology is derived from the principle of electromagnetic induction discovered by Faraday. It is a non-contact heating method. In this method, the metal is placed in an alternating electromagnetic field. Through the phenomenon of electromagnetic induction, an alternating current is generated on the metal surface, that is, eddy current. , using the Joule heating principle of eddy currents to heat metal devices. The heating speed of induction heating is very fast, which is much faster than that of the original ordinary coal, charcoal, firewood, etc., and induction heating is non-contact heating, the surface of the heating device is less oxidized, and the material loss of the heating device is also less. Many devices in the heating dev...

Problems solved by technology

[0004] Foreign countries and Taiwan have successfully developed and introduced to the market the tool handle thermal charging system based on electromagnetic induction heating, but the price is expensive, and it is only suitable for matching heated tool handles

However, there is no report on the research and development of this equipment in China. The independent research and development of the tool holder thermal charging device with intellectual property rights will be of great significance. Greatly promote the development of high-speed precision machining technology in China
