Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detection device technology, and in particular to an ultrasonic flaw detection device for circular workpieces. Background Technology

[0002] Ultrasonic flaw detection devices for circular workpieces are commonly used in fields such as machinery manufacturing and aerospace to detect flaws in circular workpieces such as shafts and tubes. Their function is to use the characteristics of ultrasonic waves to accurately detect internal or surface defects in the workpiece, such as cracks and pores, thereby ensuring workpiece quality and preventing equipment failures or safety accidents caused by defects.

[0003] In practical applications, existing ultrasonic flaw detection devices for circular workpieces, using ultrasonic transducers and coupling agents, can meet the basic requirements for workpiece inspection, but the following problems still exist:

[0004] When performing flaw detection on small circular workpieces, it is common to manually hold the probe to inspect the outer surface of the workpiece. However, since the outer surface of a circular workpiece has a certain curvature, the probe will inevitably deviate from the outer surface of the workpiece during the inspection process, resulting in poor overall fit and affecting the accuracy of the inspection. Therefore, this application provides an ultrasonic flaw detection device for circular workpieces to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an ultrasonic flaw detection device for circular workpieces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic flaw detection device for circular workpieces, comprising a detector and a probe disposed at the bottom of the detector, and further comprising;

[0007] An auxiliary component includes a wheel disposed on the side of the probe, a protective shell disposed on the side of the wheel, a support plate fixed to the inner wall of the protective shell, a fixing rod disposed on the side of the support plate, and a mounting plate fixed to one end of the fixing rod.

[0008] The support assembly includes a mounting bracket mounted on the top of the protective housing, the inner wall of which is fixed with a mounting seat.

[0009] Furthermore, a sliding groove is provided on the side of the support plate, and one end of the fixing rod extends into the inner cavity of the sliding groove, and the one end of the fixing rod is slidably connected to the inner cavity of the sliding groove.

[0010] The technical effect of adopting the above technical solution is that by opening the sliding groove, the movement trajectory of the fixed rod can be limited.

[0011] Furthermore, a top cover is fixed to one end of the fixing rod, and a groove is provided on the side of the wheel.

[0012] The technical effect of adopting the above technical solution is that by setting a top cover, the fixed rod can be prevented from detaching from the inner cavity of the slide during movement. By opening a groove, the fixed rod can be synchronously driven to move horizontally when the wheel rotates.

[0013] Furthermore, the mounting plate has an inner cavity with a mounting groove, and the inner wall of the mounting groove is fixed with an elastic joint.

[0014] The technical effect of adopting the above technical solution is that by opening the mounting groove, installation space can be provided for the flexible joint and the auxiliary wheel.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] By rotating the wheel connected to the side of the protective shell, the position of the mounting plate can be manually adjusted to facilitate its contact with the outer surface of the circular workpiece. The support plate fixed to the inner wall of the protective shell, together with the fixing rod, can limit the movement trajectory of the mounting plate to ensure that the position of the mounting plate does not shift. By setting the mounting plate, the probe can be assisted in the detection of the workpiece, ensuring that the probe is always in contact with the outer surface of the workpiece during the detection process. By setting the mounting bracket, the mounting base can be supported, and by setting the mounting base, the probe can be supported. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: an ultrasonic flaw detection device for circular workpieces, including a detector 1 and a probe 11 disposed at the bottom of the detector 1, and further comprising;

[0027] Auxiliary component 2 includes a wheel 21 disposed on the side of probe 11, a protective shell 22 disposed on the side of wheel 21, a support plate 23 fixed on the inner wall of the protective shell 22, a fixing rod 26 disposed on the side of the support plate 23, and a mounting plate 28 fixed at one end of the fixing rod 26.

[0028] The support assembly 3 includes a mounting bracket 31 installed on the top of the protective shell 22. A mounting base 33 is fixed to the inner wall of the mounting bracket 31. A sliding groove 24 is provided on the side of the support plate 23. One end of a fixing rod 26 extends into the inner cavity of the sliding groove 24 and is slidably connected to the inner cavity of the sliding groove 24. A top cover 25 is fixed to one end of the fixing rod 26. A groove 27 is provided on the side of the wheel 21. A mounting groove 211 is provided in the inner cavity of the mounting plate 28. An elastic joint 29 is fixed to the inner wall of the mounting groove 211, and an auxiliary wheel 210 is fixed to the side of the elastic joint 29. When it is necessary to inspect a circular workpiece, one end of the workpiece is placed in the inner cavity of the protective shell 22, and then the wheel 21 is manually rotated clockwise. This causes one end of the fixing rod 26 to move along the inner cavity of the groove 27 towards the center of the protective shell 22, thereby enabling... The mounting plate 28 can be moved. During the movement of the groove 27, the movement trajectory of the groove 27 can be limited by the cooperation of the slide 24 and the groove 27. The top cover 25 fixedly connected to one end of the fixed rod 26 can ensure that the fixed rod 26 will not leave the inner cavity of the slide 24 during the movement. When the mounting plate 28 moves to a certain position, one end of the auxiliary wheel 210 contacts the outer surface of the workpiece, thereby completing the fit with the workpiece. During the fit process, the elastic joint 29 is set to buffer the stress generated by the contact between the auxiliary wheel 210 and the workpiece, so as to avoid damage to the workpiece. After the mounting plate 28 is adjusted to a suitable position, the probe 11 can be moved downward by the cooperation of the mounting bracket 31 and the mounting base 33, thereby achieving the effect of fitting the probe 11 to the outer surface of the workpiece. The auxiliary component 2 and the support component 3 work together to assist the probe 11 in its detection work, ensuring that the probe 11 is always in contact with the outer surface of the workpiece during the detection process. At the same time, it can adapt to round workpieces of different sizes, effectively enhancing overall adaptability and improving work efficiency. By setting the auxiliary wheel 210, the workpiece can be assisted to move in translation within the inner cavity of the protective shell 22 during the detection process, ensuring smooth movement.

[0029] Furthermore, such as Figure 2 As shown: A snap-fit ​​block 32 is fixed to the side of the mounting bracket 31. The mounting bracket 31 installed on the top of the protective shell 22 can support the probe 11 and the mounting base 33. By setting the mounting base 33, the height of the probe 11 can be adjusted to accommodate round workpieces of different sizes. By setting the snap-fit ​​block 32, the position of the wheel 21 can be fixed to avoid displacement of the wheel 21 during the detection process, which would lead to positioning failure.

[0030] like Figure 1-4 As shown:

[0031] In use: First, place one end of the circular workpiece into the inner cavity of the protective shell 22. Then, manually rotate the wheel 21 clockwise to drive the fixing rod 26 to move along the inner cavity of the groove 27 towards the center of the protective shell 22. This will drive the mounting plate 28 to move via the fixing rod 26. When the mounting plate 28 moves to a certain position, one end of the auxiliary wheel 210 contacts the outer surface of the workpiece, and the elastic joint 29 deforms to a certain extent, thus enabling the auxiliary wheel 210 to fit against the outer surface of the workpiece. After adjustment, move the locking block 32 to fix the position of the wheel 21. Then, by adjusting the mounting base 33, push the probe 11 to the outer surface of the workpiece. Finally, by external power supply, start the probe 11 and the detector 1 to perform the detection work on the circular workpiece.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
