Description

Technical Field

[0001] The present invention relates to the technical field of welding quality detection devices, and in particular to a patrol-type weld detection device. Background Art

[0002] Weld inspection is the quality control of welded metal products, typically performed using non-destructive testing (NDT). NDT is a method of detecting defects without damaging the performance or integrity of the material or finished product being inspected, primarily focusing on appearance testing.

[0003] For example, the prior art (CN 114700648 A) discloses a weld detection device for square steel welding, which includes an upper frame, a lower frame, a positioning assembly, a detection assembly and square steel. The lower frame is provided below the upper frame, the detection assembly is provided in the middle of the upper frame, the interior of the upper frame and the lower frame are both provided with positioning assemblies, and square steel is provided between the upper frame and the lower frame. By arranging the upper frame, the lower frame, the positioning assembly and the detection assembly, the upper frame and the lower frame cooperate, so that the device can be installed in a sleeve manner on the outside of the square steel. The arrangement of the positioning assembly enables the distance between the upper frame and the lower frame and the square steel to be adjusted, thereby ensuring the stability of the device installation to a certain extent. The detection assembly can detect the weld of the square steel, and the detection assembly slides inside the upper frame, thereby ensuring the stability of the sliding of the detection rod during the detection process, thereby improving the detection accuracy to a certain extent.

[0004] The purpose of weld inspection is to detect surface defects in welded joints, such as porosity, undercuts, weld bumps, burn-throughs, cracks, and dimensional deviations. Manual inspection devices, such as those described above, require repeated disassembly and assembly depending on the inspection area, resulting in low efficiency. More importantly, prior to inspection, all spatter and contaminants within a 10-20mm radius of the weld must be removed to ensure accurate inspection. Summary of the Invention

[0042] Specifically, notches are provided at the connection points between the left and right ends of the inner link plate 204 and the flip arm 203, which can reduce weight and manufacturing time, and also provide space for the screw transmission gear 314 to rotate;

[0043] Specifically, the lower limit seat 206 and the upper limit seat 208 are both made of rubber material with a certain elasticity, which can flexibly realize the positioning of the flip arm 203 in the non-detection state and the detection state;

[0044] A slide bar 303 is provided on one side of the movable lead screw 307 in the inspection assembly 3. The first slide bar seat 301 and the second slide bar seat 302 are fixed to the positions corresponding to the two ends of the bottom surface of the inner link plate 204. The slide bar 303 is fixedly connected between the first slide bar seat 301 and the second slide bar seat 302. The slide bar 303 is slidably connected with the slide bar 304. The side of the slide bar 304 is fixedly connected to the other end of the middle link plate 309. The bottom surface of the plate 204 is fixedly connected to the opposite first screw seat 305 at one end corresponding to the movable screw 307 and the opposite first slide seat 301. The other end of the bottom surface of the slide seat 304 is fixedly connected to the second screw seat 306 at a position coaxial with the opposite first screw seat 305. One end of the movable screw 307 is rotatably connected to the opposite first screw seat 305, and the other end of the movable screw 307 that is rotated out of the second screw seat 306 is fixedly connected to the screw rotation gear 313.

[0045] A screw transmission gear 314 is meshed with the upper side of the screw rotation gear 313. A transmission shaft 315 is fixedly connected to the position of the inner side surface of the flip arm 203 corresponding to the screw transmission gear 314. The screw transmission gear 314 is rotatably connected to the transmission shaft 315. A screw drive motor 316 is fixedly installed on the top surface of the inner link plate 204 at a position corresponding to the screw transmission gear 314.

The screw drive gear 317 is meshed with the screw transmission gear 314, and the screw drive motor 316 is electrically connected to the main control box 104.

[0046] A module protective cover 310 with a lower opening is provided on the bottom surface of the central link plate 309 at positions corresponding to the first and second patrol probes 311 and 312. The height of the module protective cover 310 is greater than that of the first and second patrol probes 311 and 312, thereby providing protection for the first and second patrol probes 311 and 312.

[0047] Before loading, the flip arm 203 is in an outward flipped state. At this time, the left and right ends of the outer end of the flip arm 203 are elastically overlapped on the two sets of lower limit seats 206.

[0048] The weld product to be inspected can be moved to the top surface of roller 107 by a crane or forklift;

[0049] Furthermore, the position of the weld product to be inspected can be fine-tuned by the independently rotatable roller 107 to ensure that the weld is aligned with the first inspection probe 311 and the second inspection probe 312 and parallel to the lateral movement direction of the center plate 309.

[0050] After the product to be inspected for weld seams is loaded, the main control box 104 is operated to start the flip drive motor 211, which drives the flip drive gear 210 to rotate forward. The flip drive gear 210 cooperates with the flip rotation gear 209 to drive the flip shaft 202 and the flip arm 203 to flip. The inward flipping of the flip arm 203 drives the inspection assembly 3 to move as a whole to the top of the weld seam.

[0051] At this time, the left and right ends of the flip arm 203 just elastically rest on the two sets of upper limit seats 208;

[0052] At this time, the middle connecting plate 309 is located at the starting end;

[0053] Then, the main control box 104 is operated to start the screw drive motor 316, which drives the screw drive gear 317 to rotate. The screw drive gear 317 and the screw transmission gear 314 form a coordinated transmission. The screw transmission gear 314 and the screw rotation gear 313 form a coordinated transmission. The screw rotation gear 313 coaxially drives the rotation of the movable screw 307. The movable screw 307 and the screw slider 308 form a coordinated transmission. The screw drive motor 316 controls the forward and reverse switching of the screw drive gear 317 to achieve the forward and reverse switching of the movable screw 307, thereby achieving the switching of the lateral movement direction of the screw slider 308.

[0054] The lateral movement of the lead screw slider 308 drives the lateral movement of the central link plate 309 and the first patrol probe 311 and the second patrol probe 312 installed on the bottom surface of the central link plate 309;

[0055] By moving the first patrol probe 311, the area with the risk of welding defects can be preliminarily identified, and then the second patrol probe 312 is moved and the area with the risk of welding defects is further carefully inspected. By first identifying the risk target area and then conducting detailed inspections on the risk area, the accuracy of the inspection can be further improved.

[0056] Example 2: Based on Example 1, the present invention realizes the example of linkage cleaning work in the vicinity of the weld during weld detection. Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the linkage fixed teeth 401 in the linkage cleaning assembly 4 are fixed to the bottom surface of the inner link plate 204 in parallel with the movable lead screw 307, and the left and right sides of the middle link plate 309 are symmetrically rotated with linkage gears 402, and the two sets of linkage gears 402 are engaged with the linkage fixed teeth 401, and the left and right sides of the middle link plate 309 are also symmetrically rotated with cleaning brush discs 403, and the two sets of cleaning brush discs 403 are respectively connected to the corresponding linkage gears 402 in transmission.

[0057] The two groups of linkage gear seats 404 in the linkage cleaning assembly 4 are symmetrically fixedly connected to the left and right ends of the central connecting plate 309, and the side surfaces of each group of linkage gear seats 404 are rotatably connected to the positions corresponding to the linkage gears 402 with linkage gear shafts 405. The two groups of linkage gears 402 are respectively plugged and fixed in the corresponding linkage gear shafts 405, and the outer shaft end of each group of linkage gear shafts 405 is also plugged and fixed with a linkage bevel gear 406. The left and right ends of the central connecting plate 309 and the positions corresponding to each group of linkage bevel gears 406 are also fixedly connected with cleaning rotary seats 407, and the bottom surface of each group of cleaning rotary seats 407 is rotatably connected with a cleaning rotary shaft 408. The center position of the axis of each group of cleaning rotary shafts 408 is plugged and fixed with a rotating bevel gear 409, and the two groups of rotating bevel gears 409 are respectively meshed with the corresponding linkage bevel gears 406;

[0058] A threaded post 410 is provided at the bottom end of each cleaning shaft 408 at a position corresponding to the cleaning brush disc 403. A locking nut 411 is provided in the inner hole of the bottom end of the cleaning brush disc 403. After the cleaning brush disc 403 is inserted into the threaded post 410, the locking nut 411 is threadedly connected to the threaded post 410 to fix the cleaning brush disc 403 on the cleaning shaft 408.

[0059] Since most welding products are metal substrates and the welding process is mostly a front-end process, the cleanliness of the metal substrate surface is poor. In addition, a large amount of welding slag will be generated near the weld during the welding process. In order to ensure the accuracy of weld detection, the area near the weld needs to be cleaned;

[0060] When the central link plate 309 moves laterally, it will drive the linkage gears 402 arranged at the left and right ends of the central link plate 309 to form a coordinated transmission with the linkage fixed teeth 401 fixed on the bottom surface of the inner link plate 204, thereby driving the linkage gear 402 to rotate as the central link plate 309 moves. The rotation of the linkage gear 402 can coaxially drive the rotation of the linkage bevel gear 406. The linkage bevel gear 406 and the rotating bevel gear 409 form a coordinated transmission, which can drive the rotation of the cleaning shaft 408. The cleaning shaft 408 can drive the rotation of the cleaning brush plate 403 that contacts the surface of the product to be inspected for the weld. Through the rotation of the cleaning brush plate 403, dirt near the weld can be removed, and the rotation of the cleaning brush plate 403 is linked with the lateral movement of the central link plate 309, which can ensure the accuracy of weld detection on the basis of energy saving.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
