[0001] The utility model relates to the technical field of weld detection equipment, in particular to a weld detection equipment. Background Art

[0002] At present, small welding equipment on the market can meet certain requirements and has a low cost, thus being welcomed by small and medium-sized enterprises. However, for the welded parts of steel rings, due to the lack of specific clamping tooling, the existing small welding equipment cannot quickly detect the welded parts, and the detection reliability is not high. Content of the Utility Model

[0003] Based on this, in view of the above problems, it is necessary to provide a weld detection equipment that can quickly clamp the steel ring and ensure that the clamped steel ring can quickly enter the weld detection area to carry out weld detection work.

[0004] A weld detection equipment includes a base. On the left and right sides of the top of the base, there are support frames. On both support frames, there are installed toothed plates. On the two toothed plates, there are blocks clamped with them. On the two blocks, there is a top plate rotatably connected. On the back of the two top plates, there are buffer components. The bottoms of the two buffer components are hinged to the toothed plates at the ends far from the blocks, and the other ends of the two buffer components are hinged to the back of the top plates. At the center of the front of the two top plates, there is an arc-shaped plate for lifting the steel ring.

[0005] As a preferred solution, on both sides of the top of the base, there are installed locking columns and first brackets for supporting the locking columns. The first brackets are fixedly connected to the base, and the locking columns are installed on the tops of the first brackets.

[0006] As a preferred solution, an ultrasonic detector is installed on the base between the two support frames. The ultrasonic detector performs ultrasonic scanning detection on the welded part.

[0007] As a preferred solution, the buffer component includes a piston cylinder and a piston rod. One end of the piston rod is hinged to the arc-shaped plate. The piston rod is inserted into the piston cylinder, and the piston cylinder and the piston rod are slidably matched. The other end of the piston cylinder is hinged to the toothed plate.

[0008] As a preferred solution, a centering displacement component for driving the two support frames to approach each other is installed inside the base. The centering displacement component is used to adjust the distance between the two support frames.

[0009] As a preferred solution, the centering displacement assembly includes a first guide rail, a sliding seat, a first connecting rod and a turbine. There are four first guide rails, two on each of the left and right sides, and the four first guide rails are all installed on both sides inside the base. There are two sliding seats, and the two sliding seats are respectively in sliding fit with the first guide rails on the left and right sides. A turbine is arranged between the two sliding seats. The turbine is rotatably connected inside the base. There are two first connecting rods, and the two first connecting rods are eccentrically rotatably connected to the turbine. The other ends of the two first connecting rods are rotatably connected to the corresponding sliding seats.

[0010] As a preferred solution, a worm meshing with the turbine is arranged inside the base. The two ends of the worm are connected to the inside of the base through bearing seats, and a first motor for driving the worm to rotate is installed inside the base.

[0011] As a preferred solution, the support frame includes a first mounting plate, a first T-shaped mounting block and a second T-shaped mounting block. The sliding seat has a first mounting portion and a second mounting portion. The bottom of the first T-shaped mounting block is fixedly connected to the first mounting portion.

The upper part of the first mounting plate is connected to the toothed plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By clamping and centering the steel ring with the left and right arc-shaped plates, the steel ring can be restricted from breaking away. The arc-shaped plates are hinged to the center of the top plate, so that the arc-shaped plates can rotate around the top plate as a support. During the process of lifting the steel ring, the arc-shaped plates can fit with the outer wall of the steel ring at a better angle and with the largest contact area. The top plate is supported on the toothed plate through the clamping block and the buffer assembly. The clamping block is clamped with the toothed plate. Therefore, the buffer assembly, the toothed plate and the top plate form a movable triangle, which can change the inclination state of the top plate, change the position of the clamping block on the toothed plate according to the actual force conditions, and make the overall force more stable. As a support, the buffer assembly can greatly eliminate the impact force. Description of the Drawings

[0021] As Figures 1 - 3 shown,

[0022] As an alternative embodiment,

[0023] A weld detection device, comprising a base 1, support frames 2 are provided on both the left and right sides of the top of the base 1, toothed plates 3 are installed on both support frames 2, engaging blocks 6 are installed on the two toothed plates 3, a top plate 7 is rotatably connected to the two engaging blocks 6, a buffer assembly 4 is provided on the back of the two top plates 7, the bottom of the two buffer assemblies 4 is hinged to the toothed plate 3 at the end far from the engaging block 6, and the other end of the two buffer assemblies 4 is hinged to the back of the top plate 7. An arc-shaped plate 8 for supporting the lifting steel ring 9 is hinged at the center of the front surface of the two top plates 7.

[0024] In the above structure, when it is necessary to detect the welding part 11 of the steel ring 9, the steel ring 9 can be placed between the two arc-shaped plates 8 through a suspension device, so that the left and right arc-shaped plates 8 lift the steel ring 9 to make it in a suspended state, and then the subsequent weld detection device is used to detect the welding part of the steel ring 9. During this process, the arc-shaped plate 8 is hinged to the center of the top plate 7, so that the arc-shaped plate 8 can rotate around the top plate 7 as a support, and can fit the outer wall of the steel ring 9 at a better angle and with the largest area during the process of lifting the steel ring 9. At the same time, the top plate 7 is supported on the toothed plate 3 through the engaging block 6 and the buffer assembly 4, and the engaging block 6 is engaged with the toothed plate 3, so the buffer assembly 4, the toothed plate 3 and the top plate 7 form a movable triangle, that is, the inclination state of the top plate 7 can be changed, and the position of the engaging block 6 on the toothed plate 3 can be changed according to the actual force conditions, making the overall force more stable. In addition, when the suspension device places the steel ring 9 between the two arc-shaped plates 8, some impact forces will be generated, so the buffer assembly 4 is designed as a support to greatly eliminate the impact forces.

[0025] On the basis of Embodiment 1, as Figure 1 shown:

[0026] Locking columns 10 and first brackets 12 for supporting the locking columns 10 are installed on both sides of the top of the base 1. The first brackets 12 are fixedly connected to the base 1. The locking columns 10 are installed on the top of the first brackets 12 and can be closely attached to the inner wall of the steel ring 9 through the left and right two locking columns 10, while the outer wall of the steel ring 9 is supported by the arc-shaped plate 8, so that the arc-shaped plate 8 and the locking columns 10 cooperate inside and outside to fix the position of the steel ring 9.

[0027] An ultrasonic detector 5 is installed on the base 1 between the two support frames 2. The ultrasonic detector 5 performs ultrasonic scanning detection on the welding part 11, and the detected data in the ultrasonic detector 5 is processed by the data processing module and then sent to the cloud for storage and displayed on the terminal interface, which is convenient for the operator to observe, manage and post-process.

[0028] The buffer assembly 4 includes a piston cylinder 41 and a piston rod 42. One end of the piston rod 42 is hinged to the arc-shaped plate 8. The piston rod 42 is inserted into the interior of the piston cylinder 41, and the piston cylinder 41 is in sliding fit with the piston rod 42. The other end of the piston cylinder 41 is hinged to the toothed plate 3. When the piston rod 42 is subjected to a downward impact, the bottom of the piston cylinder 41 supports on the toothed plate 3, and the piston rod 42 will continuously penetrate into the interior of the piston cylinder 41 and compress the gas inside the piston cylinder 41, thereby alleviating the downward impact.

[0029] On the basis of Embodiment 1, Figure 2 as shown:

[0030] A centering displacement assembly for driving the left and right support frames 2 to approach each other is installed inside the base 1. The centering displacement assembly is used to adjust the distance between the two support frames 2. The centering displacement assembly includes four first guide rails 13, sliding seats 14, first connecting rods 15, and a turbine 16. There are four first guide rails 13, two on each of the left and right sides, and the four first guide rails 13 are all installed on both sides inside the base 1. There are two sliding seats 14, and the two sliding seats 14 are respectively in sliding fit with the first guide rails 13 on the left and right sides. A turbine 16 is arranged between the two sliding seats 14. The turbine 16 is rotatably connected inside the base 1. There are two first connecting rods 15, and the two first connecting rods 15 are eccentrically rotatably connected to the turbine 16. The other ends of the two first connecting rods 15 are rotatably connected to the corresponding sliding seats 14.

[0031] Among them, the centering displacement assembly is used to adjust the distance between the two support frames 2, and finally adjust the distance between the two arc-shaped plates 8, so as to adapt to steel rings 9 of different diameters. Four first guide rails 13 are installed, two on each side inside the base 1, and the four first guide rails 13 are arranged in a matrix. Rotating the turbine 16 rotates at the center inside the base 1, which can drive the left and right first connecting rods 15 to pull the corresponding sliding seats 14 to displace on the corresponding first guide rails 13, realizing the synchronous approach or synchronous separation of the two sliding seats 14.

[0032] A worm 17 meshing with the turbine 16 is arranged inside the base 1. The two ends of the worm 17 are connected to the inside of the base 1 through bearing seats. A first motor 18 for driving the worm 17 to rotate is installed inside the base 1. Subsequently, only by controlling the first motor 18 can the adjustment of the distance between the two arc-shaped plates 8 be realized.

[0033] Such as Figure 3As shown, the support frame 2 includes a first mounting plate 21, a first T-shaped mounting block 22, and a second T-shaped mounting block 23. The sliding seat 14 has a first mounting portion 141 and a second mounting portion 142. The bottom of the first T-shaped mounting block 22 is fixedly connected to the first mounting portion 141, and the first T-shaped mounting block 22 is connected to the second mounting portion 142. The top ends of the first T-shaped mounting block 22 and the first T-shaped mounting block 22 pass through the top of the base 1 and are connected below the first mounting plate 21. The first mounting plate 21 is connected to the toothed plate 3 above.

[0034] During use, only need to start the first motor 18. The first motor 18 drives the worm 17 to rotate, and then the worm 17 drives the turbine 16 to rotate inside the base 1. Thus, the left and right sliding seats 14 are driven by the left and right first connecting rods 15 to slide on the first guide rail 13, so that the left and right sliding seats 14 approach or move away from each other. This causes the two first mounting plates 21 on the left and right support frames 2 to approach or move away from each other, ultimately realizing the change in the distance between the two arc-shaped plates 8. While this distance changes, it can ensure that the ultrasonic detector 5 is always at the center of the gap between the two. The change in the distance between the two arc-shaped plates 8 is for the weld detection of steel rings 9 with different diameters.

[0035] The above embodiments only represent several implementation manners of the present utility model, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
