This X, Y kinetic control system adopt the motion of orthogonal transverse axis (axle X) and transverse axis (axle Y), and design has the zero-bit switch on X, Y-axis, i.e. the mechanical origin of system, the security that moves by the limit switch assurance system at each end of travel.Drive its slide rule and scale of going up inductosyn during motion and do relative motion, produce sine and cosine induced potential signal, after device converts thereof into digital quantity, send Single Chip Microcomputer (SCM) system to handle, obtain the coordinate figure of each.
When carrying out work, adopt the mode of human-computer interactive control image data, the motion control electronics gauge head of coordinate axis sends interruption by the electronics gauge head to Single Chip Microcomputer (SCM) system in X, Y plane motion, and the coordinate of this point is gathered in request.If will stipulate track route, the coordinate of key point can be organized in the middle of the corresponding program, realize the track route that needs with small X, Y shift simulation.Control as for the speed and the residence time can realize by the working condition that changes stepper motor.Therefore determine that with the method the working condition of swing has good software flexibility.
When working automatically, the student holds the handle of torch handle 10 and the shell of welding wire handle 20 (torch handle 10 is only held in electric welding, and the non-melting electrode argon arc welding both hands are held the handle of torch handle 10 and the shell of welding wire handle 20 simultaneously).Torch handle 10 and welding wire handle 20 under the control of computer control, rotate a set angle with torch handle telecontrol equipment 40 and welding wire handle motion device 50.Simultaneously, welding rod in torch handle 10 or the welding wire handle 20 or welding wire are simulated wire melting and are moved upward under the control of computer control, torch handle 10 or welding wire handle 20 then move downward with identical speed with the slide block on torch handle telecontrol equipment 40 and the welding wire handle motion device 50, keep the distance between welding rod or welding wire and the workpiece constant.Torch handle telecontrol equipment 40 is swung along Y direction under the effect of torch handle pendulous device 60 simultaneously, and moves along X-direction.And welding wire handle motion device 50 is in the same moved further of the effect lower edge of torch handle pendulous device 60 X-direction.Teach by doing as old welder master worker, make the student can grasp proper operation rapidly.
Torch swinging in the welding process can increase weld width, for uneven weld seam of weld width and enhancement welding bead surface aesthetic practical significance is arranged.Simultaneously, the swing welding can reduce layer thickness, realizes that easily multi-pass welding connects, and helps improving the mechanical property of weld metal.The general requirement of weave bead welding termination process is that swing speed and amplitude of fluctuation are adjustable.Higher requirement be except swing speed and amplitude of fluctuation stepless adjustable, left and right sides amplitude of oscillation place's residence time also can be regulated.Wherein swing speed requires linear adjustable.Even swing speed can speed change be regulated in swing process.Therefore the motion to oscillation system requires very high.
When welding simulator is in auto state, because the motion process of simulation welder operation is discontinuous rectilinear motion, for example the swing of wire feed motion and Y-axis all transfers by the motor leading screw is positive and negative that to drive nut slider reciprocating, and actual motion and the setting error between moving will be caused in the gap between nut and the leading screw.For overcoming this problem, improve the feed screw nut transmission accuracy in the telecontrol equipment, the present invention has also installed synchronous shift absolute value comparator circuit (as shown in Figure 5).Described synchronous shift absolute value comparator circuit comprises the angular displacement gauge head that is arranged on the CD-ROM drive motor and is located at axial displacement gauge head on nut or the slide block, length standard, and numbered card.Tally card is with certain sampling interval synchronous acquisition angular displacement signal and gauge head axial displacement signal, the signal processing system that is had by tally card itself is carried out high multiple with two paths of signals and is sent computer system to after electronic fine-grained, be displacement by corresponding software with conversion of signals again, handle calculating the leading screw error amount by computer control in real time.Two paths of signals does not send out contact any between Computer Processing, make them become the angle reference amount and the axial displacement of leading screw helix by Computer Processing, and by relatively calculating error amount.According to resultant error amount, carry out the oneself and adjust, reach accurately control of operation.
Telecontrol equipment provided by the present invention utilizes X, Y coordinate control system, can reach route and speed by the software control swing fully, and the corresponding two ends residence time.
