Description
Technical field
The utility model relates to the device that the drive screw rodb base moves on the automatic coil winding machine, particularly a kind of lead screw device on straight line.
Background technology
Many appliance components all can be used coil windings, like transformer, and loud speaker etc.In order to make the appliance component quality more really up to the mark, the arrangement of coil windings just must be compact and accurate.Need make in the process of automatic coil winding machine coiling screw rodb base frequent move and also the efficient of coiling and precision and lead screw device are closely related.So a reliable operation of active demand, the lead screw device that precision is high.
The utility model content
The purpose of the utility model provides a kind of simple in structure, reliable operation, the lead screw device that can make screw rodb base high efficiency, high precision movement on straight line that precision is high.
The scheme that the utility model solve the technical problem is: a kind of lead screw device, and it comprises screw rodb base and support, the bottom of support is provided with the clutch shaft bearing seat board; The middle and upper part of support is provided with second bearing plate, and the top of support is provided with the 3rd bearing plate, on the 3rd bearing plate servomotor is set; On second bearing plate screw mandrel shaft block is set, ball screw is set on the screw mandrel shaft block, ball screw is connected with servomotor; The spiral maintainance block is set on the ball screw, and the front of support is provided with guide rail, and moving slider is set on the guide rail; Screw rodb base and spiral maintainance block are fixed, and screw rodb base and moving slider are fixed.
As further technical scheme again, between said the 3rd bearing plate and the screw mandrel shaft block shaft coupling is set, ball screw is connected with said servomotor through shaft coupling.
As further technical scheme, a side of said screw rodb base is provided with sensor board, and a side of said support vertically is provided with 2 transducers, and sensor board is between 2 transducers.
As further technical scheme again, said transducer is " U " shape transducer.
As further technical scheme again, the bottom of said support is provided with circular stop piece.
As technical scheme further, the quantity of said guide rail is 2, is provided with about 2 guide rails, and the quantity of said moving slider also should be 2 mutually.
The utility model drives the ball screw rotation through the rotation of servomotor, and ball screw passes second bearing plate, promotes or retract the spiral maintainance block through rotation, thereby drives screw rodb base moving along guide rail.In addition; When screw rodb base moves to certain position; The sensor board that is fixed on screw rodb base one side will get in " U " shape of transducer, will make transducer change signal like this, and signal is transferred to control system; Control servomotor stall or rotation in the opposite direction again, and then the direction of rotation and the moving direction of control screw mandrel.In addition, the bottom of support is provided with circular stop piece, and circular stop piece plays the security protection effect.If control system takes place unusual, screw rodb base surpasses predetermined maximum moving distance, continues to move down, and circular stop piece will stop the spiral maintainance block, the fail safe of assurance device.
In sum, the utility model is not only simple in structure, reliable operation, efficient, safety, and possesses higher automaticity.
