Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of numerical control plasma cutting machine cutting torch hunting gear.
Background technology
Mostly the motor that present known numerical control plasma cutting machine cutting torch is heightened follower is to have the brush direct current generator; Control circuit is an analog control mode; The hunting gear of this structure because use is direct current generator, needs to increase rectifier and reduction box; There is complex structure, the problem that maintenance cost is high, service life is short; Its control mode is to adopt external interpolation control device in addition, and control mode is analog control mode, the adjustment low precision, and complicated operation, fault rate is high, so the out-of-flatness of workpiece otch.
Summary of the invention
For the operation that makes numerical control plasma cutting machine simpler; Increase work efficiency cut quality with workpiece; The utility model provides a kind of numerical control plasma cutting machine cutting torch hunting gear; This device can high-precision automatic adjustment burning torch and workpiece between vertical range, have simple in structure, easy to operate, the measured advantage of cut workpiece matter.
The utility model solves the scheme that its technical problem adopted:
A kind of numerical control plasma cutting machine cutting torch hunting gear; It comprises shell, stepper motor, screw mandrel, litter and burning torch and master control system; Wherein, Stepper motor, screw mandrel, litter setting and concern that according to upper-lower position stepper motor connects that screw mandrel, screw mandrel are connected with litter, litter is connected with burning torch in the enclosure; Master control system comprises micro computer and a lead-out terminal, two input terminals, ACK button, decline button and rising buttons of being connected with micro computer; 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.
A kind of numerical control plasma cutting machine cutting torch hunting gear is provided with rising stop and decline stop in the described shell.
A kind of numerical control plasma cutting machine cutting torch hunting gear, the micro computer of described master control system are can realize that analog quantity arrives the CPU that digital quantity changes.
In the utility model when work,, the decline button of pressing master control system drops to apart from workpiece the plasma burning torch to be fit to the distance of cutting and to start numerical control cutting machine carry out cutting apart from trial cut, when distance is suitable; Press ACK button; Master control system is promptly noted current cutting distance and is got into automatic tracking mode, and distance changes between workpiece and plasma burning torch, and the plasma arc voltage also changes thereupon; And signal is passed to micro computer through two input terminals; Signal produces corresponding pulse number and direction signal after micro computer A/D conversion and computing, pass to the lead-out terminal drive stepping motor by micro computer; Stepper motor drives screw mandrel and rotates slide bar to be done move both vertically and drive the plasma burning torch and move both vertically, and makes plasma burning torch and workpiece remain the cutting distance when initial; Slide bar is done when moving both vertically, and realizes Stroke Control when rising or after dropping to certain height through rising stop, decline stop; As when cutting, increasing or reduce the distance between plasma burning torch and the workpiece, crawl rising button or decline button plasma burning torch can rise or drop to the desired position automatically and remember current distance automatically.
A kind of numerical control plasma cutting machine cutting torch of the utility model hunting gear; Owing to heighten the employing stepper motor; Press variation through the electric arc between induction burning torch and the workpiece; Electric arc presses the signal that changes to convert data signal to, can avoid direct current generator to produce magnetic field induction in the course of the work, improves antijamming capability; Can realize digital simple and easy control, simple to operate, can improve servo-actuated precision and workpiece kerf quality greatly; Because the stepper motor antijamming capability is strong, can improve the physical life of product simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is a kind of numerical control plasma cutting machine cutting torch of the utility model hunting gear structure and embodiment sketch map.
Among the figure, shell 1, stepper motor 2, screw mandrel 3, litter 4, decline stop 5, rising stop 6, burning torch 7, micro computer 8, lead-out terminal 9, input terminal 10, input terminal 11, confirming button 12, rising button 13, decline button 14, workpiece 15.
The specific embodiment
As shown in the figure; A kind of numerical control plasma cutting machine cutting torch hunting gear, it comprises shell 1, stepper motor 2, screw mandrel 3, litter 4 and burning torch 7 and the master control system of being made up of micro computer 8, lead-out terminal 9, input terminal 10, input terminal 11, confirming button 12, rising button 13, decline button 14; Wherein, stepper motor 2, screw mandrel 3, litter 4 are arranged in the shell 1, and concern that according to upper-lower position stepper motor 2 connection screw mandrels 3, screw mandrel 3 are connected with litter 4, litter 4 is connected with burning torch 7; The lead-out terminal 9 of master control system is connected with stepper motor 2, and input terminal 10 is connected with burning torch, and input terminal 11 is connected with workpiece 15; 1 also is provided with rising stop 6 and decline stop 5 in the shell.
As shown in the figure, in the utility model when work,, the decline button 14 of pressing master control system drops to apart from workpiece 15 burning torch 7 to be fit to the distances of cutting and to start numerical control cutting machine carry out cutting apart from trial cut; When distance is suitable, press ACK button 12, master control system is promptly noted current cutting distance and is got into automatic tracking mode; Distance changes between workpiece 15 and burning torch 7; The plasma arc voltage also changes thereupon, and through input terminal 10 and input terminal 11 signal is passed to micro computer 8, and signal is after micro computer 8A/D conversion and computing; Produce corresponding pulse number and direction signal; Pass to lead-out terminal 9 drive stepping motor 2 by micro computer 8, stepper motor 2 drives screw mandrels 3 and rotates slide bar 4 to be done move both vertically and drive burning torch 7 and move both vertically, and makes burning torch 7 and workpiece 15 remain the cutting distance when initial.As the time need increasing or reduce the distance between burning torch and the workpiece in cutting, crawl rising button 13 or decline button 14 also send to stepper motor 2 through lead-out terminal 9 with signal and burning torch 7 is risen automatically or drop to the desired position and the current distance of memory automatically.
