The symmetrically arranged X-axis slide rail 45 and the symmetrically arranged Y-axis slide rail 46 can well support the connecting bracket 4 during the alignment process, so that it can be stably connected with the alignment power mechanism, and the alignment effect is better.

[0026] Specifically, the X-axis servo driver 5 includes an X-axis AC servo motor 52 and an X-axis reducer 53, the motor shaft of the X-axis AC servo motor 52 is connected with the input shaft of the X-axis reducer 53, the output shaft of the X-axis reducer 53 is connected with an X-axis adjusting lead screw 54, and the X-axis sliding pair 51 is connected with the X-axis adjusting lead screw 54 through threads. Through the driving of the X-axis AC servo motor 52, the X-axis adjusting lead screw 52 can be driven to rotate accurately, so as to realize the X-direction displacement control of the connecting bracket 4 through the thread cooperation with the X-axis sliding pair 51. The Y-axis servo driver 6 includes a Y-axis AC servo motor 62 and a Y-axis reducer 63, the motor shaft of the Y-axis AC servo motor 62 is connected with the input shaft of the Y-axis reducer 63, the output shaft of the Y-axis reducer 63 is connected with a Y-axis adjusting lead screw 64, and the Y-axis sliding pair 61 is connected with the Y-axis adjusting lead screw 64 through threads. Through the driving of the Y-axis AC servo motor 62, the Y-axis adjusting lead screw 62 can be driven to rotate accurately, so as to realize the Y-direction displacement control of the connecting bracket 4 through the thread cooperation with the Y-axis sliding pair 61.

[0027] The device is used with a deviation measuring instrument, a deviation measuring instrument 8 is arranged in front of a machine head of a production line, the deviation measuring instrument 8 is the X-RAY8000NXT deviation measuring instrument of Siecora, Germany, the deviation measuring instrument 8 has the advantages of reliable operation and high precision.Utilizing the deviation measuring instrument 8 as a detection feedback device, and a PLC controller, and a deviation adjusting mechanism (an X-axis servo driver 5 and a Y-axis servo driver) constitute an automatic control system, and an automatic deviation adjusting task is completed.The X-axis servo driver 5 and the Y-axis servo driver 6 are controlled by the PLC controller, and the deviation measuring instrument 8 is connected with the PLC controller in signal.Through the driving of servo motors, the X and Y directions of the insulation layer flow channel can be controlled by the push of a connecting support 4.Because the deviation measuring instrument 8 is detected by the scanning of X-rays in two perpendicular X and Y directions, the detection action is intermittent, so the control process also adopts intermittent action.When the deviation measuring instrument 8 measures that the deviation data changes more than the set dead zone range, the adjusting action is started, the adjusting amount is determined by proportional calculation, after adjustment, the next detection result is waited, the adjusting direction and adjusting amount are determined according to the calculation result, so that the eccentricity of the insulation layer gradually enters the set range.The dead zone range is equivalent to the required range of eccentricity, the dead zone range data is set, and the eccentricity control precision is determined.
