And the positioner of the welding that matches with manipulator is generally complete set of equipments, can't manually control and cooperates welding by hand, uses dumbly, and the input of equipment is larger.

The utility model content

The technical problems to be solved in the utility model provides a kind of positioner, can be used with manipulator, also can be used with manual welding, uses flexibly, can effectively reduce the input of equipment.

For achieving the above object, the technical solution of the utility model is: a kind of positioner, comprise frame, the displacement rotating shaft, speed changer, displacement rotating shaft and speed changer are contained on the frame, one end of displacement rotating shaft is fixed the anchor clamps that a holding workpiece is used, the other end of displacement rotating shaft is connected with the output shaft of speed changer by shaft coupling, servomotor and PLC controller also are housed on the frame, the output shaft of servomotor is connected the power shaft of speed changer with synchronous pulley driving mechanism by Timing Belt, the PLC controller is by the running of motor servo driver control servomotor, be fixed with conducting ring in the displacement rotating shaft, carbon brush be housed on the frame match with described conducting ring.

Further improve, described frame is provided with emergency stop switch and shutdown switch, and emergency stop switch is used for cutting off external power source under the state of emergency, and shutdown switch shuts down servomotor by the PLC controller; Stop the running of positioner after making things convenient for the running that stops positioner under the state of emergency or normal operation to finish.

Further improve, described frame side is provided with foot-operated point driving switch, and foot-operated point driving switch makes the running of servomotor gap by the PLC controller; When making things convenient for manual welding, trick cooperates the raising welding efficiency.

Further improve, described frame is provided with manual point driving switch, and manual point driving switch makes the running of servomotor gap by the PLC controller; Improve the flexibility of using.

Preferred described speed changer is the multi-stage gear speed changer; Improve the displacement precision.

Further improve, described PLC controller is provided with the I/O interface and is connected by the manipulator control interface of holding wire with the outside, controls servomotor running by the PLC controller by motor servo driver by the enabling signal of manipulator; Conveniently be connected with the manipulator control interface.

The utility model is owing to be equipped with servomotor and PLC controller in frame, and the output shaft of servomotor is connected the power shaft of speed changer by Timing Belt with synchronous pulley driving mechanism, and the PLC controller turns round by motor servo driver control servomotor; Therefore can manually control the running of servomotor gap by the PLC controller conveniently matches with manual welding; Then be connected by the manipulator control interface of holding wire with the outside and pre-enter program by the PLC controller, then the enabling signal by manipulator starts the running of control servomotor by the PLC controller, shifting one's position of displacement rotating shaft matched with the movement locus of manipulator, the utility model is matched with manipulator carry out automatic welding, so the utility model uses flexibly, can effectively reduce the input of equipment.
