Forging refers to the method of applying pressure or impact force to a metal material to cause it to undergo plastic deformation and become a metal blank or part with the required geometric shape, size and organizational properties, so it is also called pressure processing. The workpiece is Forgings. Forgings are formed by forging and pressing hot steel ingots, and there will be some defects in the production process. Forgings are important blanks for various mechanical equipment and boiler vessels. In practical applications, it bears a relatively high load. In order to ensure the safe use of equipment, it is most practical to use detection technology to detect forgings. 100% UT testing (Ultrasonic Testing, ultrasonic testing) is carried out according to the ultrasonic flaw detection standard "GB/T37400.15 General Technical Conditions for Heavy Machinery Part 15: Nondestructive Testing of Forged Steel Parts", and it is qualified if it meets the quality level I.

According to the design requirements, the excavation section of the underground construction equipment shield is very large, with a diameter ranging from 3 meters to 25 meters. The excavation diameter, construction conditions, and different geological conditions of the shield require that the design of the shield must be customized and personalized. Therefore, as one of the core parts of the main bearing of the shield machine, the ring forging is mainly characterized by large size changes, complex cross-sections, and heavy weight. The large size change is manifested by the diameter ranging from 3 meters to 9 meters, and the complex cross section is mainly reflected in the steps and grooves of various sizes, and the heaviest weight is 30 tons. The above characteristics bring the following difficulties to the flaw detection of ring forgings:

(1) Forging blanks have various specifications and complex cross-sections, and the detection volume is huge. For conventional flaw detection of ring forgings, longitudinal wave straight probes are used to scan in two directions, including radial detection on the outer circumference and axial detection on cross-section scanning. Manual scanning can only scan step by step in two directions, and the detection efficiency is low. The scanning of 8-9 meter complex ring forgings generally requires one shift.

(2) Ultrasonic flaw detection is highly dependent on the skills and sense of responsibility of the operator, and there are uncertainties such as missed inspections, inaccurate defect quantification, and inaccurate ratings.

(3) The test data and results cannot be stored, and the traceability of the test process is poor.

Therefore, manual inspection cannot meet the inspection requirements of mass production of ring forgings, a key part of bearings, and has become a bottleneck process in production.

In order to solve the above-mentioned technical problems, the present invention provides an ultrasonic testing device, which utilizes the detection and containment ring forging and coupling agent to realize full water immersion detection. The ring forging is clamped and positioned by the first driving device and the second driving device, and the ring forging is driven to rotate. An ultrasonic detection device abuts against the end face of the ring forging and moves along the end face, and an ultrasonic detection device abuts against the side of the ring forging and moves along the side. In this way, through the rotation of the ring forging and the movement of the ultrasonic detection device on the surface of the ring forging, automatic detection of multiple detection directions is realized, and the efficiency is high. Among them, the moving path of the ultrasonic testing device on the surface of the ring forging can be controlled by the control device, and the control device can record the detection data, perform analysis techniques to quantify and grade defects according to standard requirements, and finally output a flaw detection report. Wherein, the second driving device is movably connected with the detection container, and by adjusting the position of the second driving device, the first driving device and the second driving device can clamp and position ring forgings with different diameters, and drive the ring forgings to rotate. Therefore, ultrasonic testing equipment can test ring forgings of different sizes.

Specifically, the support member 341 may be a universal ball.

Exemplarily, the universal ball is a SP-150 precision heavy-duty universal ball, with an overall size of φ240mm×300mm, a ball diameter of 150mm, and a single load of 6t.

It can be understood that the radial arrangement of the support members 341 is beneficial to increase the number of contacts between the support members 341 and the ring forging 800 and increase the contact area between the support members 341 and the ring forging 800 .

One of the first detecting member 720 and the positioning member 710 is connected with the first driving assembly 310 , the other is used for connecting with the ring forging 800 , and the first detecting member 720 is configured to detect the positioning member 710 .

The second detection part 730 is connected to the second driving part 314 , and the second detection part 730 is configured to detect the rotation speed of the second driving part 314 . Both the first detection part 720 and the second detection part 730 are electrically connected to the control device 500 .

It should be noted that the number of the flaw detection and positioning device 700 is one, and the flaw detection and positioning device 700 can be arranged on any one of the two first driving assemblies 310 .

Specifically, the second detection part 730 is an encoder. The first detection part 720 is a proximity switch, and the positioning part 710 is a patch.

When working, it is necessary to basically fit the flaw detection results and the position of the ring forging 800, and quickly locate the approximate area of the defect. Since the ring forging 800 is placed on the universal ball, the coefficient of friction is small, and the clamping force ensures complete contact between the first friction member 315 and the ring forging 800, and the relative movement between the two is negligible. The linear speed of rotation of the ring forging 800 is monitored by an encoder, and then the running distance of the ring forging 800 is calibrated. Paste the patch at the starting position of the rotation, determine the time of one revolution through the proximity switch to send and receive signals, and verify each other with the running distance of the workpiece, and basically locate the defect position.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
