It should be noted that, after each station completes the action, if the detection result is qualified, the finished product is removed; if the detection is not qualified, the audible and visual alarm 15 positioned on the hood 3 gives an alarm and displays specific alarm information on a display screen of the controller 13. In addition, 1 safety grating 16 is respectively installed on two sides of the front end of the hood 3, so that the safety of operators can be protected. An automatic clamping and rotating module 18 is also arranged behind the thread locking station, and the automatic clamping and rotating module 18 is arranged on a bottom plate of the nut locking module 9; the automatic clamping and rotating module 18 is used as a special module of a built-in fan blade generator type, and the front end of the automatic clamping and rotating module is automatically and radially clamped into a groove on the circumferential surface of a claw pole of the rotor during working.
According to the generator rotor, bearing, belt pulley and nut assembling integrated machine, five stations including a rear bearing pressing station, a front end cover pressing station, a belt pulley pressing station, a locking nut station and a torque checking station are integrated, four groups of guide modules are designed to act alternately through the automatic shifting module, circular movement of a product seat 12 in an annular track module 11 is achieved, the automation degree of an assembling process is high, and an operator can complete all assembling work through single operation. The servo motor 17 on the nut locking module 9 realizes that the maximum large-torque locking torque is 250N.m, the torque error can be controlled within 7 percent, and the inclined lock and the sliding tooth can be automatically detected and an alarm signal is sent out; the bearing press-fitting module 6 detects and controls press-in force by adopting the first air cylinder and the pressure sensor, automatically stops press-in when deviating from a normal value, sends out an alarm signal, and can record, inquire and derive data of the assembly process for tracing back and carrying out quality statistics and analysis.
The nut locking module 9 is matched with the torque checking module 10 arranged on the nut locking module, so that locking torque control and detection can be realized, and the operation of each module is controlled by the controller 13 connected with the electric control cabinet; before the use, initialization and self-checking operation are required, then the servo motor 17 is controlled by a built-in non-standard self-designed control system of the electric control cabinet to screw the nut in three stages according to a set torque: assembling at the first stage, rotating the nut at the speed of 25r/min and aligning the nut with the axial center, and simultaneously detecting and calculating whether the nut is locked obliquely by a control system; the second stage is pre-locking, and the nut is quickly locked at the speed of 100 r/min; tightening in the third stage, locking the nut to a set torque at the speed of 25r/min, and simultaneously detecting whether poor sliding teeth exist; the torque sensor acquires data in the nut screwing process and feeds back the torque to the control system in real time to perform PID operation until the detected torque reaches a set value, and the screwing is completed. The maximum locking torque which can be realized by the servo motor 17 is 250N.m, and the torque error is controlled within 7 percent. When the nut is screwed up qualified, feeding back qualified information; and when the nut is not tightened satisfactorily, the press fitting is stopped and an audible and visual alarm is triggered. It should be noted that, the inclined lock and the sliding tooth are judged by monitoring and implementing torque calculation; if the lock is locked obliquely, the servo motor 17 stops rotating, and the pressing cylinder cannot reset; if the teeth slip, the servo motor 17 is operated all the time, and the push cylinder is not reset. And the two abnormal conditions can display corresponding alarm information on a display screen of the controller. In addition, the number of times of repeated screwing of the nut, the time interval and supervision of the reverse rotation of the nut sleeve after the nut is screwed can be set according to actual requirements, so that the nut sleeve is conveniently separated from the nut.
The generator rotor, the bearing, the belt pulley and the nut assembly integrated machine is also reserved with a remote data uploading function, a corresponding program is made in an autonomously designed control system in an electric control cabinet, an interface is reserved, and data interaction is carried out with a remote computer in real time through a network, so that automatic remote data uploading, remote monitoring and control are conveniently realized; screwing up data and bearing power of impressing and realizing automatic recording and analysis that gathers, can easily realize the quality management and control.
