Economical gantry type numerical control drilling machine control system based on PLC

Abstract

A PLC-based economical gantry-type CNC drilling machine control system includes two parts: an electrical control system and a hydraulic control system. The electrical control system mainly includes four parts, namely, the configuration monitoring part of the upper computer, the PLC control part, the x-y axis servo positioning motion control part, the main shaft frequency conversion speed regulator and the hydraulic power drilling feed part. The control system adopts PLC as the position control method of the controller. The high-speed pulse output corresponds to the pulse signal required by the servo system input. The frequency determines the displacement speed of the axis, the number of pulses determines the displacement distance, and the pulse value sign determines the direction of movement. The system takes the programmable controller as the core, adopts the upper computer, servo controller, sensor and hydraulic technology, so that the CNC drilling machine has the functions of precise positioning and automatic drilling.

Description

technical field [0001] The invention relates to a PLC-based economical gantry type numerical control drilling machine control system, which is suitable for the mechanical field. Background technique [0002] In the drilling process of steel structure plates, if the traditional manual clamping, positioning, and drilling methods of ordinary drilling machines are used, there are problems such as high labor intensity, long auxiliary time, low production efficiency, and unstable product quality. However, due to the high price of the commercialized numerical control system, for the relatively simple processing of plate drilling, it inevitably causes waste of resources to a certain extent, and cannot meet the requirements of popular use. The PLC-controlled gantry-type special CNC drilling machine and its control system can solve the above problems. It has the characteristics of strong flexibility, stable processing quality, high efficiency, simple operation, economical and practica...
