1st, project outline
This project is two axes holes processing engine bed, this kind of processing equipment present situation is:
A, uses traditional the hydraulic equipment processing precision to be low, the efficiency is not high;
B, the equipment environment adaptiveness is not strong;
C, uses the hydraulic system, therefore the maintenance of equipment work frequent and is relatively tedious.
In order to solve the above problem, this engine bed has used the time IMS series servocontrol. The time IMS servocontrol has the following characteristic:
A, may realize the electrical machinery steady movement to 0.01Hz ~ 250Hz operating region;
B, the electrical machinery operating speed is lower than when 50Hz may realize 3 time of electrical machinery nominal torque output, (effectively solved in work piece processing process including the electrical machinery 0Hz locking time 3 time of electrical machinery nominal torque output occasionally to appear stops up transfers phenomenon, had guaranteed component processed high efficiency output);
C, in sets at the PLC function (16 to enter /13), programs the way through QMCL software to carry on to all I/O from the definition design. Uses the I/O way receive corresponding movement signal and informs position PLC 滑台 whether has completed the work piece processing process, in the work piece processing process two servo controllers mutually between also mutually lock the function by the I/O way realization;
D, uses the QMCL language translation the procedure, may the nimble hypothesis electricity zero spot, the parameter establishment bias value which defines through the procedure guarantee the mechanical home position and an electrical zero reliable union. Moreover compensates the quantity and the mechanical bond by the software basis mechanical actual situation design gap is closer, because each kind compensates is does for the parameter hypothesis, therefore may creates according to the actual situation and the long time use the gap change makes the corresponding adjustment. Enormously has facilitated the system debugging and the peace-keeping.
E, the system parameter wilfully establishes the electrical machinery to move the time S curve and the torque limits the peak-to-peak value.

2nd, project implementation orientation lecture
First fixedly reigns the work piece through the jig on the drilling machine central work table. After presses down "the movement" the button, the cabin door will shut down, is located the work table beginnings and ends the actuation electrical machinery to have the drill bit through the ball bearing guide screw to approach the position a processing high speed advancement to the work piece, after will arrive approaches the position to produce the electric signal by the controller to cause the drill bit work, then will carry on the processing according to the inherent deep hole processing circulation. In order to prevent the relative two drill bits hit the knife, realizes by the controller through the software programming two actuates the electrical machinery mutually to lock the function. Namely first processes to approaches median line some position the actuation electricity opportunity to send out the signal to lock in other one side the actuation electrical machinery, causes it to enter "the suspension" the condition, waits the electrical machinery to return after the safety seat relieves the original electric signal to cause other one side the actuation electrical machinery to continue to complete its own processing movement. After the work piece processing completes, the controller will produce the corresponding electric signal to turn on the cabin door and the waiting next time the cyclic action "the movement" the start.
Two axes holes special-purpose processing drilling machine integrated system schematic drawing has see Figure 1.

Chart 12 axis hole special-purpose processing drilling machine integrated system schematic drawing

Each enters for the axis actuation electrical machinery carries on the position control by the IMS servo controller, the IMS servo controller (PG) the feedback signal constitutes the position closed-loop system through the corresponding encoder. All electric signal and so on limit switch, zero position switch straight unites into the corresponding controller to do for the control signal. 2 servo controllers use interior integration PLC function, is connected (basis different user's request through the I/O signal and the control panel, also may use the RS422/485 communication way to carry on corresponding segment). Because this set of equipment correlation parameter did not hope can establish by the equipment operator, therefore on the control panel certainly does not have the parameter hypothesis function, displaced uses has been possible to insert immediately pulls out the type 手操�?way to carry on the revision to the correlation parameter (to carry on revision by correlation technical personnel).

Chart 2 shows for the single actuation motor-driven corresponding drill bit work piece processing process, visible does "fast approaches the work piece - idling speed processing work piece - quickly returns at once draws back" the circulation processing movement reciprocation process.

Software establishes "mutually locks" the signal to divide into "locks opposite party" (output) the signal and "response locking" (input) the signal, when the IMS controller control actuation electrical machinery will drill an advancement to will approach core some position (software hypothesis), the controller will be able to produce to other controller "locks opposite party" the signal. After opposite party controller accepts "response locking" the signal, if is working in the safe area, then normal operation; If is prompting forward and has the possibility to occur hits the knife situation, then carries out "the suspension" the movement to cause to drill to pause in the margin for safety until "response locking" loss of signal. Sends out "locks opposite party" the signal controller in to drill which controls to return draws back after the margin for safety, "will lock opposite party" the signal cancellation in order to other side will drill a normal operation. Two controllers in line with "first impressions ares most lasting" the principle carry on mutually lock the movement guarantees when the processing the high efficiency output.
