Technical Field

Background

At present, the ultrasonic detection of the ring forging is mainly carried out by using a conventional ultrasonic instrument or a phased array detector, and a detector holds a conventional straight probe or a phased array probe to move on the end face of the ring forging so as to carry out the ultrasonic detection. The manual scanning mode mainly has the defects of large influence of human factors, consumption of human resources, incapability of accurately recording the defect position, difficulty in repeatedly positioning the defect position and the like.

As shown in FIG. 3, the ultrasonic detection scanning device for the ring forging comprises a support 2, wherein the support 2 is used for fixing the ring forging 1 and is also used for supporting a ring scanning workbench 3. The annular scanning workbench 3 can rotate to perform annular scanning movement, and can move up and down to adjust the distance from the probe to the annular forging 1. The annular scanning workbench 3 is provided with a linear guide rail 6, the linear guide rail 6 is provided with a guide rail sliding block 7, the linear guide rail 6 is further provided with a stepping motor 4, and the stepping motor 4 can drive the guide rail sliding block 7 to move on the linear guide rail 6. A fixed-scanning workbench 8 is arranged below the guide rail sliding block 7, and the fixed-scanning workbench 8 can perform rotary motion; a coupler 9 is arranged below the fixed-sweeping workbench 8, a clamping rod 10 is arranged below the coupler 9, a spring is arranged outside the clamping rod 10, and a probe chuck 11 for clamping a probe is arranged below the clamping rod 10. The spring on the outside of the clamping rod 10 allows the probe cartridge 11 to be tightly fitted to the swage.

The probe has 4 motion modes: the device comprises a clamping rod, a ring forging piece, a clamping rod, a rotating shaft, a linear guide rail, a clamping rod, a rotating shaft. And a displacement sensor is also arranged on the linear guide rail 6 and used for monitoring the radial position of the probe, and the displacement sensor can measure the displacement of the probe along the linear guide rail. The output shaft of the fixed sweeping motor in the fixed sweeping workbench 8 is connected with a first rotary encoder, the output shaft of the annular sweeping motor in the annular sweeping workbench 3 is connected with a second rotary encoder, and the angle of annular sweeping and the angle of fixed sweeping can be measured by the two rotary encoders.

The 5G module 5 may be disposed on the stepper motor 4; and the 5G module 5 is connected with the circular scanning workbench 3, the stepping motor 4 and the fixed scanning workbench 8 through a PLC controller. The control platform can be a computer with a 5G transceiving interface.

As shown in fig. 2, the control stage is used to input the inner diameter, outer diameter, thickness, ring-scan radial movement speed, ring-scan circumferential rotation speed, and fixed-scan circumferential rotation speed of the ring member.

The ring forging ultrasonic detection scanning device works under the coordination of the control platform, and a secondary control strategy is adopted, namely the control platform → the ring forging ultrasonic detection scanning device → the control platform. The specific process shown in fig. 1 is as follows:

and placing an annular workpiece, namely an annular forging on the bracket, and marking a starting point of scanning.

And starting the control platform, performing first self-checking and error analysis on the system, and giving an alarm if an error occurs.

When the system is normal, inputting the inner diameter, the outer diameter and the thickness of the ring piece, the radial moving speed of the circular scanning, the circumferential rotating speed of the circular scanning and the circumferential rotating speed of the fixed scanning in the control platform; the probe automatically adjusts the radial position, the circumferential position and the height position to the marked starting point according to input data, and transmits the starting point position to the PLC controller, and the PLC controller can transmit the starting point position to the control platform through the 5G module.

And then the control platform starts the annular scanning motor, and the probe starts radial scanning along the innermost side of the ring piece. If suspected defects are detected, signals are transmitted to the control platform, the control platform transmits instructions, the probe is commanded to be repeatedly positioned at the position, and the complete defect appearance and the corresponding position are detected; if no defect is detected, the control platform commands the probe to move to the next position continuously, and the detection is continued.

After the circumferential inspection is finished, the control platform automatically issues an instruction to enable the stepping motor to operate, the probe moves by one size along the radial direction, and the circumferential scanning is continuously started. And performing circumferential and radial coordination until the detection is finished, outputting the number and the accurate coordinates of the defects, and clicking the coordinates to check the appearance of the defects.
