The testing agency of backgauge described in the present invention has bearing seat, has through hole in bearing seat, and thread bush is housed in through hole, and adjusting screw(rod) is housed in thread bush, between thread bush outer wall and bearing seat through-hole wall, adds insulation sleeve; An end at the relative clamp case of adjusting screw(rod) feeding centre bore is equipped with adjusting lock nut and backgauge head; Also have a radial direction through hole on bearing seat, insulation tube and connection bolt are housed in radial direction through hole, connection bolt also is connected with adjusting screw(rod) with thread bush through insulation sleeve.
Adjusting screw(rod) in the testing agency of backgauge described in the present invention is coaxially arranged with the feeding centre bore of clamp case.
Engineering philosophy of the present invention is: wire rod is sent into by the feeding centre bore, the backgauge head is controlled the length of wire rod input, open the rotation of pincers cam and drive rear fork by roller, the motion of rear fork drives the opening and closing of clamp, the swing of rocker is with the side-to-side movement of movable pendulum frame, thereby carry out the gripping of wire rod, by regulating the position of backgauge head, can accurately control the length of wire rod input, when short material situation occurring, when wire rod does not contact with the backgauge head, the sensor that the backgauge head connects sends a signal to controller, controller sends a signal to cylinder again, cylinder propulsion arm control clamp is not closed, thereby this short material is not carried out to gripping, short material falls down calcellation automatically.
The present invention can detect short material automatically, and short material is refused to gripping, and production efficiency is high, detects accurately, greatly reduces labor strength.
