Description

A kind of torch cutting follow-up device of numerical-control plasma

Technical field

The utility model relates to the cutting machine field, more specifically to a kind of torch cutting follow-up device of numerical-control plasma.

Background technology

The motor that current numerical control plasma cutting machine cutting torch is heightened follower mostly has been brushless motor, control circuit is analog control mode, the hunting gear of this structure, due to what use, it is direct current generator, need to increase rectifier and reduction box, have complex structure, maintenance cost is high, the problem that service life is short; Its control mode is to adopt external interpolation control device in addition, and control mode is analog control mode, adjusts low precision, and complicated operation, so the out-of-flatness of workpiece otch.

The utility model content

The purpose of this utility model is to overcome the deficiency of present technology, provides a kind of simple to operate, the torch cutting follow-up device of numerical-control plasma of high efficiency.

The utility model is achieved by the following technical programs.

The utility model torch cutting follow-up device of numerical-control plasma, comprise shell, stepper motor, screw mandrel, sliding lush, burning torch and master control system, in described shell, be provided with lifting position-limit device and descending spacing device, wherein stepper motor, screw mandrel, sliding lush setting are in the enclosure, and concern that according to upper-lower position stepper motor is connected to screw mandrel, screw mandrel is connected with litter, and sliding lush is connected with burning torch; Master control system comprises micro computer and a lead-out terminal, two input terminals, ACK button, decline button and rising buttons of with micro computer, being connected; The lead-out terminal of master control system is connected with stepper motor, and one of them input terminal is connected with burning torch, and another input terminal is connected with workpiece.

The advantage that the utility model is compared with conventional art is: simple to operate, high efficiency, improve the workpiece kerf quality, improves the service life of product.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model torch cutting follow-up device of numerical-control plasma.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

In Fig. 1, the utility model torch cutting follow-up device of numerical-control plasma, the utility model torch cutting follow-up device of numerical-control plasma, comprise shell 1, stepper motor 2, screw mandrel 3, sliding lush 4, burning torch 7 and by micro computer 8, lead-out terminal 9, input terminal 10, input terminal 11, confirming button 12, rising button 13, the master control system that decline button 14 forms, in described shell 1, be provided with lifting position-limit device 6 and descending spacing device 5, described stepper motor 2, screw mandrel 3, sliding lush 4 is arranged in described shell 1, and be connected to described screw mandrel 3 according to the described stepper motor 2 of upper-lower position relation, described screw mandrel 3 is connected with described sliding lush 4, described sliding lush 4 is connected with burning torch 7, the lead-out terminal 9 of described master control system is connected with stepper motor 2, and one of them input terminal 10 is connected with burning torch 7, and another input terminal 11 is connected with workpiece 15.

During the utility model work, the decline button 14 of pressing master control system drops to apart from workpiece 15 burning torch 7 to be applicable to the distance of cutting and to start numerical control cutting machine carrying out cutting apart from trial cut, when distance is suitable, press ACK button 12, master control system is namely recorded current cutting distance and is entered automatic tracking mode, distance changes between workpiece 15 and burning torch 7, the plasma arc voltage also changes thereupon, and by two input terminals 10 and 11, signal is passed to micro computer 8, signal is after micro computer 8A/D conversion and computing, produce corresponding pulse number and direction signal, by micro computer 8, pass to lead-out terminal 9 Driving Stepping Motors 2, stepper motor 2 drives screw mandrels 3 and rotates and make sliding lush 4 do to move both vertically and drive burning torch 7 to move both vertically, cutting distance while making burning torch 7 and workpiece 15 remain initial, sliding lush 4 is done while moving both vertically, and by lifting position-limit device 6, descending spacing device 5, realizes Stroke Control when rising or after dropping to certain height, if in cutting, the time increased or reduce the distance between burning torch 7 and workpiece 15, crawl rising button 13 or decline button 14 burning torches 7 are understood automatic-ascendings or are dropped to desired position and distance that automatic Memory is current.
