Abstract
The utility model discloses an automatic device of screwing up of bolt, including AC servo motor, AC servo motor's output is connected with the reduction gear, and the output of reduction gear is connected to the uide bushing through the sensor, and the output of uide bushing is connected to the sleeve through the integral key shaft, the sensor includes angle sensor and torque sensor. The utility model discloses can detect the moment of torsion, detection angle, and then detect out the bolt and whether twist to the sleeve and screw up the quality, can also guarantee the location of bolt on the horizontal direction, improved the efficiency and the success rate of screwing up.
Description
Technical field
This utility model relates to a kind of device for screwing up, is specifically related to a kind of bolt automatic screwing device.
Background technology
It is bolted in various plant equipment extensively apply.But in current factory, what workpeople or big multiplex manual wrench carried out screw thread tightens installation, and this leverages the efficiency of work, and screwed tight effect is barely satisfactory.And it cannot be guaranteed that error in the horizontal direction when bolt is tightened, tighten of poor quality.
Utility model content
The purpose of this utility model is to provide a kind of bolt automatic screwing device, to overcome the problems of the prior art, this utility model can detect moment of torsion, detection angles, and then detect whether bolt is screwed to sleeve and tightens quality, the location of bolt can also be ensured in the horizontal direction, improve the efficiency and success rate tightened.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of bolt automatic screwing device, including AC servo motor, the outfan of AC servo motor connects decelerator, and the outfan of decelerator is connected to fairlead by sensor, the outfan of fairlead is connected to sleeve by splined shaft, and described sensor includes angular transducer and torque sensor.
Further, described decelerator is planetary reducer.
Further, the outfan of decelerator is connected with sensor by shaft coupling.
Further, all fastened by screw between AC servo motor and decelerator, decelerator and shaft coupling, shaft coupling and sensor and sensor and fairlead.
Further, described screw is hexagon socket cap head screw.
Further, the downside of screw is provided with spring washer.
Compared with prior art, this utility model has a following useful technique effect:
This utility model is in use, the high rotating speed of AC servo motor output and little moment of torsion change into through decelerator and tight a bolt the required slow-speed of revolution and high pulling torque passes to twist splined shaft, pass to bolt to be tightened through sleeve implement to tighten, sensor will detect to obtain torque signal, angle signal feeds back to controller, output signal to AC servo driver after being computed and control servomotor, fairlead ensures location and the transmission of bolt in the horizontal direction, torque sensor and angular transducer detect moment of torsion and angle, and then detect whether bolt is screwed to sleeve and quality is tightened in raising；Adding fairlead between splined shaft and sensor, fairlead can ensure location and the transmission of bolt in the horizontal direction, improves the precision tightened；Sleeve have employed modularized design, can change at any time, to adapt to various various sizes of bolt；Sleeve and fairlead are connected by splined shaft, and spline bearing loading capability is high, and centering is good, and guidance quality is good, and stress collection is medium and small, easy to process, can improve the precision tightened.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Seeing Fig. 1, a kind of simple bolt automatic screwing device, it includes sleeve 1, splined shaft 2, fairlead 3, sensor 4, planetary reducer, AC servo motor 6, hexagon socket cap head screw and normal type single coil spring lock washer composition.Planetary reducer one end is connected with AC servo motor 6, and the other end is connected with sensor 4 by shaft coupling；Sensor 4 is connected with fairlead 3 again, and fairlead 3 is connected by splined shaft 2 with sleeve 1；Each parts are fastenedly connected further through hexagon socket cap head screw and normal type single coil spring lock washer, and wherein, sleeve 1 have employed modularized design, can change at any time, to adapt to various various sizes of bolt；Sleeve 1 and fairlead 3 are connected by splined shaft 2, splined shaft 2 bearing capacity is high, centering is good, guidance quality is good, stress collection is medium and small, easy to process, the precision tightened can be improved, fairlead 3 is added between splined shaft 2 and sensor 3, fairlead 3 can ensure location and the transmission of bolt in the horizontal direction, improve the precision tightened, sensor 4 includes angular transducer and torque sensor, the moment of torsion suffered by bolt and angular error can be detected when tightening, and then by data feedback to controller, judge to tighten quality, planetary reducer and AC servo motor 6 all use standardized designs, easily change when damaging.
Below operating process of the present utility model is described in detail:
See Fig. 2, the workflow of this device for screwing up is as follows: AC servo motor 6 provides power, the high rotating speed of AC servo motor 6 output and little moment of torsion change into through planetary reducer and tight a bolt the required slow-speed of revolution and high pulling torque passes to twist splined shaft 2, pass to bolt to be tightened through sleeve 1 and implement to tighten.Sensor 4 will detect torque signal, angle signal feed back to controller, output signal to after being computed AC servo driver control servomotor.Fairlead 3 ensures location and the transmission of bolt in the horizontal direction.
