[0047] The following Figure 1 and Figure 2 describe in detail a weld detection device provided by the present application.

[0048] The present application provides a weld detection device for detecting the quality of a weld. The weld detection device includes a support assembly, a laser positioning assembly, and an ultrasonic detection assembly.

[0049] Specifically, the support assembly has a first support portion, a second support portion, and a link support portion; the first support portion and the second support portion are respectively disposed on both sides in the width direction of the weld, and both ends of the link support portion are respectively connected to the first support portion and the second support portion, that is, the link support portion spans across the weld in the width direction of the weld; in combination with Figure 1 as shown, the link support portion is located above the weld.

[0050] Specifically, the laser positioning assembly is disposed on the link support portion and the laser beam emitted by it is aligned with the center line of the weld.

[0051] Specifically, the ultrasonic detection assemblies are respectively disposed on the first support portion and the second support portion, and the sound beams emitted by the ultrasonic detection assembly on the first support portion to the weld and the sound beams emitted by the ultrasonic detection assembly on the second support portion to the weld are symmetric about the laser beam.

[0052] Preferably, the laser positioning assembly is a laser, and the ultrasonic detection assembly is an ultrasonic probe 15.

[0053] In summary, (1) In this application, the laser emitted by the laser positioning component always hits the center of the weld. Based on the laser beam (i.e., based on the center line of the weld), the ultrasonic detection components on both sides of the weld are symmetrically arranged, which can ensure that the sound beams emitted by the ultrasonic detection components on both sides of the weld can completely cover the weld, thereby improving the detection efficiency and accuracy. (2) When the moving support component moves, it can drive the ultrasonic detection component to move along the length direction of the weld. Also, since ultrasonic detection components are respectively arranged on both sides of the weld, when the support component moves, data can be collected twice for the weld simultaneously, reducing the number of collections. (3) When the support component moves along the length direction of the weld, in order to always ensure that the ultrasonic detection component is symmetric about the weld, that is, to ensure the stability of the circuit, this application is provided with a laser positioning component. Based on the laser emitted by the laser positioning component, the detection structure is made more reliable.

[0054] It should be noted that: since this application needs to detect the quality of the weld, the support component needs to move along the length direction of the weld. For the movement of the support component, a manual movement method can be selected, or an automatic movement method can be selected. The automatic movement method can be driven by a motor.

[0055] In addition, the ultrasonic probe 15 in this application adopts an ultrasonic phased array detection method, which can record and store data, can more objectively reflect the detection situation; can realize data reconstruction and computer imaging, and the detection results are more intuitive; it is easy to realize automatic detection to obtain higher detection efficiency.

[0056] In this embodiment, in combination with Figure 1 as shown, the support component includes a first support frame 4 that can serve as the first support part, a second support frame 6 that can serve as the second support part, and a connecting rod 3 that can serve as the connecting rod support part.

[0057] Specifically, both the first support frame 4 and the second support frame include a first support frame 4 and a second support frame 6 connected in an L shape; among them, the second support frame 6 on the first support frame extends towards the opposite side, and the second support frame 6 on the second support frame extends towards the opposite side, so that the second support frame 6 on the first support frame and the second support frame 6 on the second support frame are respectively located on both sides in the width direction of the weld.

[0058] Furthermore, both ends of the connecting rod 3 are respectively arranged on the first support frame 4 on the first support frame 4 and the second support frame 6 on the second support frame, so that the connecting rod 3 is located above the weld.

[0059] Specifically, the laser positioning assembly is disposed on the connecting rod 3. Further, the emitting end of the laser positioning assembly faces the weld seam located below the connecting rod 3; the ultrasonic detection assemblies are respectively disposed on the second support frames 6 on the first support frame and the second support frames 6 on the second support frame, and the ultrasonic detection assemblies and the weld seam are on the same horizontal plane.

[0060] In this embodiment, as shown in combination with Figure 1 and Figure 2 , the laser positioning assembly is disposed on the connecting rod 3 through a clamping member.

[0061] Specifically, the clamping member includes a first clamping portion and a second clamping portion connected to the first clamping portion.

[0062] Further, the first clamping portion is connected to the connecting rod 3, and the laser positioning assembly is fixed to the second clamping portion.

[0063] Furthermore, the first clamping portion includes a sleeve 7, a first screw 9, and a first nut. Among them, the sleeve 7 is sleeved on the connecting rod 3, the first screw 9 passes through the sleeve 7 in the radial direction of the sleeve 7 and abuts against the connecting rod 3, and the first nut is screwed onto the first screw 9 so that the sleeve 7 is fixed to the connecting rod 3.

[0064] During the actual use process: the first nut can be loosened from the first screw 9, so as to cancel the locking of the sleeve 7, and then the sleeve 7 can be manually driven to move on the connecting rod 3, so that the laser head moves to directly above the weld seam, and further the laser beam emitted by the laser is emitted to the center position of the weld seam.

[0065] In this embodiment, the second clamping portion includes a collar 10 and a first locking member 11.

[0066] Specifically, the collar 10 is fixed to the sleeve 7, and its axis is parallel to the emission direction of the laser beam; a limiting space is formed inside the collar 10, and the laser can be inserted into the collar 10 and locked to the collar 10 through the first locking member 11.

[0067] Further, the first locking member 11 includes a second screw and a second nut. After the laser is inserted into the collar 10, the second screw passes through the collar 10 in the radial direction of the collar 10 and abuts against the laser, and then the second nut is tightened on the second screw to realize the positioning of the laser.

[0068] Furthermore, there are multiple locking members, and the multiple locking members are arranged at intervals along the circumferential direction of the collar 10; thus, the stable fixation of the laser in the circumferential direction of the collar 10 is realized.

[0069] Furthermore, considering that the laser has a certain length, in order to improve the stable fixation of the laser, a plurality of collars 10 are provided, and the plurality of collars 10 are arranged at intervals along the emission direction of the laser beam; that is to say, the plurality of collars 10 will achieve positioning in the axial direction of the laser pointer.

[0070] In this embodiment, in combination with Figure 1 As shown, the second support frame 6 includes a first rod 12 and a second rod 13.

[0071] Specifically, the first rod 12 and the second rod 13 extend along the extension direction of the weld and are arranged at intervals along the extension direction of the weld, so that a clamping space 14 is formed between the first rod 12 and the second rod 13.

[0072] Specifically, the ultrasonic detection component is locked in the clamping space 14 through the second locking member 16.

[0073] Further, the second locking member 16 includes a third screw. In the actual use process, the ultrasonic detection component is placed in the clamping space 14, that is, the ultrasonic detection component is placed between the first rod 12 and the second rod 13, and then the third screw passes through the first rod 12 and the second rod 13 respectively and abuts against the ultrasonic detection component at the same time, so as to realize the positioning of the ultrasonic detection component.

[0074] Specifically, both the first rod 12 and the second rod 13 are telescopic rods. In the actual use process, it may be that the sleeve 7 is close to the first support frame or the second support frame. Then, in order to ensure that the distance between the ultrasonic probe 15 on the first support frame 4 and the laser beam is equal to the distance between the ultrasonic probe 15 on the second support frame 6 and the laser beam, the first rod 12 and the second rod 13 are set as telescopic rods, and during use, the position of the ultrasonic probe 15 can be adjusted through the telescopic rods.

[0075] Further, the telescopic rod is understandable to those skilled in the art. For example, the telescopic rod includes n multi-section rods, the n multi-section rods are sleeved in sequence, one of the adjacent rods is provided with a limiting hole near one end of the other rod, and the other of the adjacent rods is provided with a limiting protrusion near one end of the one rod, and the limiting protrusion can be inserted into the limiting hole to realize the fixation of the adjacent section rods.

[0076] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on 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 scope of the technical solutions of the embodiments of the present application.
