In conjunction with Fig. 2, the upper and lower of the vertically movable guide rail 323 is also correspondingly provided with upper limit position switch 327, lower limit respectively Bit switch 328, upper limit position switch 327, lower position switch 328 corresponding control axle assembly 1 reaches upward, downwards most respectively for position The position of the block selecting displacement of the big limit;The upper limit position switch 327, lower position switch 328 are electrically connected with laser sensor 220, So that servo-control mechanism sends out corresponding stopping or rotation instruction after block selecting in place.
As shown in fig. 6, the rotary drive mechanism 33 includes being fixed on the company by anti-" F " type motor fixing frame 330 Rotary electric machine 331 (Grating Angle Sensor 34 is fixed on 331 downside of rotary electric machine) on fishplate bar 324, the rotary electric machine 331 It is fixed with one by shaft coupling 332 and fixed connection shaft 333, fixed connection shaft 333 is connected with torque and force snesor 30 and is One.
As a shown in Figure 6, the fixed connection shaft 333 is fixed on by firm bearing 334 on motor fixing frame 330;Institute It includes d-axis 3333 to state fixed connection shaft 333, and the axle body of the d-axis 3333 is equipped with circular boss 3331, the boss 3331 are fixedly connected on by positioning pin 3332 on d-axis 3333;The firm bearing 334 is fixed at the boss 3331.
For this testboard in order to further ensure that the reliability and stability of workpiece test, the head of the pressure head 212 passes through plastics One end of retaining sleeve and control axle assembly fixed frame 11 is fixed;The clamping cylinder 23 passes through plastic protective sleeve and control axle assembly 1 axis lower end is fixed.
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 Dress.
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.
