Automatic unlocking iron disc device of roll-dividing machine and control method of automatic unlocking iron disc device

Abstract

The invention relates to an automatic unlocking iron disc device of a roll-dividing machine and a control method of the automatic unlocking iron disc device. The automatic unlocking iron disc device comprises a forward-pushing motor, a main shaft, a lifting air cylinder, a servo motor, an oil cylinder and a clutch, wherein the forward-pushing motor pushes an iron disc to be positioned, the lifting air cylinder pushes a cushion block to be positioned, and the iron disc corresponds to the cushion block in position; a screw locking block is fixed to one end of the main shaft and corresponds to screw holes in the iron disc and the cushion block in position; the servo motor is fixedly connected with the main shaft and can drive the main shaft to rotate; the oil cylinder is fixedly connected with the main shaft through the clutch and can drive the main shaft to rotate. Screws are locked in advance through the servo motor and are locked in a large torsion mode through the oil cylinder and the clutch, and in the process of releasing the iron disc, the screws are unlocked in a large torsion mode through the oil cylinder and the clutch and then are rapidly disassembled through the servo motor, so that manual operation of operators is replaced, and standardized operation is achieved.

Description

technical field [0001] The invention relates to a device for automatically releasing and locking an iron plate of a coiler and a control method thereof. Background technique [0002] During the operation of the coiler, it is necessary to fix the block on the iron plate with screws, and then wind the welding wire on the iron plate. When disassembling the iron plate, the screws must be removed before the welding wire can be removed. At present, in the process of locking the screw, the operator uses a wrench to use a large force to achieve the pre-compression torque when the screw is locked; The pressure on the screw increases and the friction force increases. Therefore, the operator often needs to spend more force when loosening the screw than when locking the screw, and the process of loosening the screw depends entirely on the experience of the operator. The randomness is very large, and it is difficult to realize standardized operations. Contents of the invention [000...
