CNC control based control system device for projection welding machine

Abstract

The invention discloses a CNC control based control system device for a projection welding machine. The CNC control based control system device comprises a central control unit CNC, a clamp feeding mechanism, air cylinder pressurizing devices, a welding controller, an operation platform and alternating-current welding machine, wherein the operation platform is fixed through supporting legs; the central control unit CNC is fixedly mounted on a control electrical cabinet on the side wall of the alternating-current welding machine; the air cylinder pressurizing devices are arranged above and below the alternating-current welding machine; upper and lower electrodes are fixedly mounted on tail ends of the air cylinder pressurizing devices; the welding controller is further connected on the control electrical cabinet; and the clamp feeding mechanism is arranged on the operation platform. The CNC control system can effectively position workpieces quickly and accurately, is simple in structure and is relatively low in cost. CNC programs are edited in text format, programming, storing and the like can be performed outside the machine, additional memory is not occupied except from programs, and programmed teaching and programmed modifying are convenient and simple. The system composition is improved, so that the defects in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to industrial manufacturing technology, in particular to a control system device of a projection welding machine based on CNC control. Background technique [0002] The control system of the projection welding machine usually uses a programmable logic controller (PLC) as the central control unit to control the various actions of the welding host and the action of the automatic feeding mechanism. When controlling the feeding step of welding equipment, it needs to occupy the memory of the system to store the step point data. If the trajectory is more complex and there are many points, storing the point data will consume a large amount of memory in the system, resulting in a waste of cost; the programming is complex and If it is not standard, it is prone to program loopholes; it takes a long time to debug, and it is difficult to teach programming; the work load of changing the program is heavy. These are all the weak points that pri...
