Following detailed description is made to the test process of this testboard below in conjunction with the accompanying drawings.
S1, first, the whether correctly installation of detection test block.
Detection installation includes two aspects：1, detection caused by the installation of test man's mistake or test piece quality are problematic does not have
Method carries out, and the processing mode of this problem is to shut down；2, whether detection exemplar is in initial gear (N gears), if detection does not have
Have and set in N gears, system drives test block to neutral gear automatically.
Determine whether correctly to pacify 1. laser sensor 220 will detect signal and be sent in the host computer of servo-control mechanism
2. moving to shift extreme position：The driving of rotary electric machine 331 (shift gears to), turns an angle, passes through transmission
Torque sensor signal fusing judges whether to reach shift extreme position.
3. moving to shift to set to N gears：Negative direction by rotary electric machine 331 rotate 20 degree (extreme angles rotate to neutral gear
Corresponding angle)；Workpiece spindle lower end clamping cylinder 23 is unclamped, allows control axle assembly 1 to automatically revert to N gears and sets；Continue to press from both sides
Tightly.At this point, control axle assembly 1 has been in shift to neutral gear position.
4. moving to block selecting extreme position：Vertically movable motor 320 (block selecting to) drive control axle assembly 1, moves up
20mm stops (reaching the block selecting extreme position of upper limit position switch 326, laser displacement sensor detects at this time until shifting is motionless
Displacement distance, if indicating if constant to arrived extreme position.)
5. moving to block selecting to set to N gears：Negative direction moves 20mm (displacement distance of the block selecting limit to block selecting neutral gear), pine
Workpiece spindle lower end clamping cylinder 23 is opened, allows control axle assembly 1 to automatically revert to shift and is set to N gears；Continue to clamp.At this point, control
Axle assembly 1 processed has been in block selecting to neutral gear position.
So far, erector detection is completed in control axle assembly 1, and control axle assembly 1 has been in neutral gear position.
S2, detection is done by carrying out block selecting shift to test piece.
Wherein, 320 drive control axle assembly of vertically movable motor, 1 block selecting campaign, 331 drive control axle assembly of rotary electric machine
1 gearing movement.Measurement condition needs to test：It reverses gear, N-1-2, N-3-4, N-5-R gear, test combination can be freely arranged in user
And testing sequence.In test process, each sensor (laser sensor, Grating Angle Sensor, torque and force snesor)
It detects each physical quantity and is sent to host computer and shown.
