After adopting above structure, the utility model compared with prior art has advantages of following:

After fixing approach switch to be detected, make the induction end of approach switch relative with sensor block, leave certain distance between the induction end of approach switch and the sensor block, then machine operation, drive dial rotation, sensor block is rotated, when sensor block turns to the position that approaches with the induction end of approach switch, if approach switch triggers, approach switch triggered as normal this time then is not if approach switch triggers, then this time approach switch does not have triggered as normal, master controller records and shows by display device, so just can the triggering performance of approach switch be detected, if approach switch does not repeatedly have triggered as normal, then show this approach switch fault, can not use, avoid out of order approach switch to be installed on the equipment, guarantee the normal use of equipment.

As improvement, described sensor block is fixed in the lower surface of rotating disk, the below of sensor block is provided with fixed head, fixed head is provided with a plurality of circumferentially equally distributed through holes corresponding with the movement locus of sensor block, and during dial rotation, sensor block carries out circular motion, a plurality of approach switchs to be detected are individually fixed in a plurality of through holes and by screw and fix, can fix simultaneously a plurality of approach switchs on fixed head, a plurality of approach switchs are detected simultaneously, detection efficiency is high.

As further improvement, the center of described rotating disk is fixed with one with the magnet steel of dial rotation, angular transducer be fixed on the fixed head and be positioned at magnet steel under, angular transducer is fixed on the fixed head, angular transducer is passed to master controller with the residing angle of rotating disk, the residing position of sensor block is learnt in main control, and master controller learns that according to the residing position of sensor block that detector switch should trigger.

As further improving, described sensor block is fixed in the edge of the lower surface of rotating disk, makes the circumferential movement track of sensor block the longest, and the fixedly through hole of approach switch that is used for as much as possible can be set, make the quantity of the approach switch that detects simultaneously as much as possible, improve detection efficiency.

As further improving, described gauge tap comprises forward switch and reversal switch again, make motor can forward, counter-rotating, the rotation direction of sensor block can change.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in more detail.

By Fig. 1, Fig. 2, Fig. 3 as can be known, the utility model approach switch pick-up unit comprises motor 1, motor 1 vertical direction is fixed on the support, the rotating shaft of motor 1 vertically arranges, it is connected with the rotating disk 2 of horizontal positioned, the edge of the lower surface of rotating disk 2 is provided with sensor block 4, sensor block 4 rotates synchronously with rotating disk 2, the below of sensor block 4 is provided with fixed head 10, fixed head 10 is provided with a plurality of circumferentially equally distributed through holes corresponding with the movement locus of sensor block 4 101, that is to say the below of the movement locus of sensor block 4 when a plurality of through holes 101 all are positioned at rotating disk 2 rotation, when rotating disk 2 rotates, sensor block 2 carries out circular motion, so a plurality of through holes 101 are circumferentially evenly to distribute, a plurality of approach switchs to be detected 5 are individually fixed in a plurality of through holes 101 and by screw 102 and fix, described approach switch pick-up unit also comprises master controller 6, electric machine controller 7, gauge tap 8, the angular transducer 3 of the rotational angle of display device 9 and measurement rotating disk 2, the center of described rotating disk 2 is fixed with a magnet steel that rotates with rotating disk 2, angular transducer 3 be fixed on the fixed head 10 and be positioned at magnet steel under, gauge tap 8, angular transducer 3 and approach switch 5 all are electrically connected with the input end of master controller 6, the output terminal of master controller 6 is electrically connected with input end and the display device 9 of electric machine controller 7 respectively, the output terminal of electric machine controller 7 is electrically connected with motor 1, be provided with PLC in the master controller 6, electric machine controller 7 is used for motor 1 is controlled, gauge tap 8 is used for allowing people send control signals to master controller 6, master controller 6 is by 1 running of electric machine controller 7 control motors, after fixing approach switch 5, preset angle between each approach switch 5 by calculating, master controller 6 detects rotating disk 1 by angular transducer 3 and has rotated default angle, this moment, sensor block 4 should make the approach switch 5 of opposite position trigger, if detecting this approach switch 5 this moment triggers, then this approach switch 5 this time triggers normal, if detecting this approach switch 5 this moment does not trigger, then approach switch 5 does not have triggered as normal, 6 pairs of corresponding approach switch 5 record primary faults of master controller, and by display device 9 demonstrations, if an approach switch does not trigger for more than 5 time, then judge this approach switch 5 faults, can not use.
