[specific embodiment]

Embodiment:

Fig. 1-Fig. 2 is please referred to, the present embodiment is the detection device 100 of automatic tool changer cam box, is used to detect tool changing system System, the knife-changing system include cam box 101, servo motor 102 and tool arm 103, the detection device include support frame 1, Be symmetricly set on 1 two sides of support frame and for fixing the horizontal mounting plate 2 of cam box 101, the support being arranged on support frame 1 Column 3, the angle indicator 5 being arranged on angle measurement disk 4, is arranged on support frame 1 the angle measurement disk 4 on support column 3 PLC control cabinet 6 and torque spanner 7, be provided with angle measuring markings on angle measurement disk 4, be provided on angle indicator 5 Contact pin 8, when detecting, contact pin 8 are inserted into the bolt hole in knife-changing system on tool arm 103, to realize angle indicator 5 and tool arm 103 synchronous rotary.

The electric-controlled box of PLC control cabinet 6 and servo motor 102 is electrically connected, and is electrically connected with torque spanner 7.PLC control The torque curve display screen 62 and voltage value display screen 63 of maximum current display screen 61, torque spanner 7 are provided on case 6.

When detection, after knife-changing system is mounted in horizontal mounting plate 2, angle measurement disk 4 be located at tool arm 103 just under Side.
