Brushless direct current motor controlling device for tapping

Abstract

The invention relates to the technical field of machining, in particular to a brushless direct current motor controlling device for tapping. The brushless direct current motor controlling device for tapping comprises a brushless direct current motor with a position sensor, a control main board, a display operation panel, a transmission cable A and a transmission cable B. The control main board comprises a driving module, a power source processing module, a single-chip microcomputer and an optical isolation element; the display operation panel comprises an LCD screen, a micro processing chip and control setting keys. By arranging the eleven control setting keys on the display operation panel, tapping parameters are reasonably and corporately set through the control setting keys, the manual tapping motion of a technician is simulated, and an optical tapping technical scheme is realized. The LCD screen can display related information of control setting and prompt fault self-diagnosis information. The functions of an existing brushless direct current motor controlling device are expanded, automation and numerical control of tapping equipment can be realized on a matched motor controller, machining efficiency is improved, and the quality of mechanical products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a DC brushless motor control device for tapping. Background technique [0002] Tapping is the use of taps to process internal threads, which is the most widely used internal thread processing method in the machinery industry. With the continuous improvement of mechanical processing automation and product technical requirements, traditional manual tapping has been basically replaced by electric tapping. Electric tapping puts forward high requirements on the performance of the drive motor. At the same time, in order to ensure the quality of tapping and reduce production costs, Improving work efficiency also requires automation of tapping control devices. [0003] At present, tapping is generally processed by lathe or drilling machine. Because lathe or drilling machine can only provide torque, the feed, retraction speed and depth in tapping operation must be controlle...

AI Technical Summary

Problems solved by technology

[0003] At present, tapping is generally processed by lathe or drilling machine. Because lathe or drilling machine can only provide torque, the feed, retraction speed and depth in tapping operation must be controlled manually. Therefore, the product processing quality is easily affected by human factors. impact, and it is easy to cause failures such as tap breakage
