When driven by a magnet to the cutter body needs cutter, the letter corresponding to the Hall element output tray low signal, the control system upon receipt, immediately reverse the motor control turret, cover disc driven by cylindrical pins the cutter body began to reverse, reverse pin will soon fall by the anti-tank cross by disk, thus, complete the rough location. In this case, the anti-anti rely on disc by pin from the cross grooves to climb, so the blade stops rotating, custom center rack of Inner Mongolia began to decline, and the cover disc continues to reverse Jilin custom center rack, its straight groove the left side of the slope of the head cylindrical pin is pressed into a pin hole on the cutter body, after which the lower surface of the cover disk and the head begins to slide in the cylindrical pin. In the meantime, the upper end tooth meshing under the knife body gradually achieve precise positioning, after a set delay time, turret motor stops, the end of the entire tool change process. Because the worm has a self-locking vice, so turret can be stably. Requirements: quick tool change, tool change high positioning accuracy. Analysis of the failure of the system does not receive a signal turret in place, it has been non-stop until the police turn the tool change time is too long to appear. Check the following steps one at MDI (MDA) approach, namely the implementation of T0101-T0N0N (see you are using a few station turret) center frame, to see whether it is a tool turret number can not be executed. 2, in the diagnostic status, look at a few corresponding T01-T0N values ??have not changed. 3. Suppose we found only in the change occurs when the 3rd turret turn the knife kept the situation in Sichuan custom center rack, first disassemble the turret cap, put on the hair line to remove the disc on the 3rd line against 0V shorted, look at the system diagnostic status inside the corresponding value has not changed (there - bad description of the normal line of the Hall element, no - the instructions on the 3rd reel made contact oxidation) Liaoning custom center rack, Deutsche Bank mechanical domestic first brand center frame provided by the Dezhou silver Machinery Manufacturing Company Limited.
