Description

Technical Field

[0001] The utility model relates to the technical field of weld detection equipment, in particular to a weld detection device for the production of hydraulic modules. Background Technique

[0002] The weld detection device for the production of hydraulic modules is a device used to detect the quality of welds in the production of hydraulic modules. This device is usually an ultrasonic detector. The weld detection device can help manufacturers timely discover weld defects, improve production quality, and ensure the reliability and safety of hydraulic modules.

[0003] Regarding the above and existing related technologies, the inventor believes that there are often the following defects: when using an ultrasonic detector to detect the quality of welds in the production of hydraulic modules, the debris on the surface of the weld will cover or obscure the defect signals inside the weld, resulting in the ultrasonic wave being unable to penetrate the weld completely, thereby affecting the detection effect.

[0004] Therefore, the utility model provides a weld detection device for the production of hydraulic modules. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that when using an ultrasonic detector to detect the quality of welds in the production of hydraulic modules in the prior art, the debris on the surface of the weld will cover or obscure the defect signals inside the weld, resulting in the ultrasonic wave being unable to penetrate the weld completely, thereby affecting the detection effect, and to propose a weld detection device for the production of hydraulic modules.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a weld detection device for the production of hydraulic modules, including an ultrasonic detector, a connecting wire is slidably connected inside the ultrasonic detector, a detection head is electrically connected inside the connecting wire, a cleaning structure is arranged on the surface of the detection head, the cleaning structure includes an airbag, the surface of the airbag is fixedly connected to the detection head, a connecting pipe is communicated inside the airbag, and an auxiliary pipe is communicated inside the connecting pipe.

[0007] The effect achieved by the above components is that by setting the cleaning structure, when using the ultrasonic detector to detect the quality of welds in the production of hydraulic modules, the debris on the surface of the weld can be removed, so that the ultrasonic wave can penetrate the weld as completely as possible, reducing the detection error.

[0008] Preferably, a filter screen is fixedly installed on the surface of the auxiliary pipe.

[0009] The effect achieved by the above components is that the filter screen can prevent debris from entering the airbag through the connecting pipe and the auxiliary pipe.

[0010] Preferably, a clamping plate is fixedly installed on the surface of the detection head. Two auxiliary rods are fixedly inserted inside the clamping plate. A fixing plate is slidably sleeved on the arc surfaces of the two auxiliary rods. The surface of the fixing plate is fixedly connected to the airbag. A spring is sleeved on the arc surface of the auxiliary rod. The two ends of the spring are respectively fixedly connected to the clamping plate and the fixing plate.

[0011] The effect achieved by the above components is that under the elastic force of the spring, the fixing plate slides away from the detection head. While the fixing plate slides, it drives the airbag to contract, achieving the effect of assisting in driving the airbag to contract.

[0012] Preferably, a first grip is fixedly installed on the surface of the clamping plate, and a second grip is fixedly installed on the surface of the fixing plate. Anti-slip protrusions are provided on the surface of the first grip, and anti-slip protrusions are provided on the surface of the second grip.

[0013] The effect achieved by the above components is that when holding the first grip and the second grip with hands, the second grip and the first grip move closer to each other. At this time, the second grip drives the fixing plate to move, and the fixing plate drives the airbag to open, causing the airbag to inhale gas, achieving the effect of assisting in driving the airbag to open.

[0014] Preferably, a limiting structure is provided on the surface of the ultrasonic detector. The limiting structure includes a mounting frame. The surface of the mounting frame is fixedly connected to the ultrasonic detector. A positioning frame is slidably sleeved on the surface of the mounting frame. A mounting pad is fixedly installed on the surface of the positioning frame. The mounting pad is an elastic pad.

[0015] The effect achieved by the above components is that by setting the limiting structure, when using the ultrasonic detector, the plug on the connecting wire can be limited on the ultrasonic detector, so that the connecting wire will not fall off the ultrasonic detector.

[0016] Preferably, a guiding hole is formed on the surface of the mounting frame. A rectangular plate is slidably connected to the inner wall of the guiding hole. The surface of the rectangular plate is fixedly connected to the positioning frame.

[0017] The effect achieved by the above components is that the positioning frame can slide along the surface of the mounting frame with the assistance of the rectangular plate. When the positioning frame slides on the surface of the mounting frame, the positioning frame cannot slide out of the surface of the mounting frame, and at the same time, the positioning frame will not rotate.

[0018] In summary:

[0019] 1. In the present utility model, when it is necessary to use an ultrasonic detector to detect the weld quality during the production of a hydraulic module, the fixed plate slides away from the detection head under the action of the spring elastic force. While the fixed plate slides, it drives the airbag to contract. During the contraction process of the airbag, the airbag discharges the gas along the connecting pipe and the auxiliary pipe. During the gas discharge process, the sundries on the weld will be blown off. By setting the cleaning structure, when using an ultrasonic detector to detect the weld quality during the production of a hydraulic module, the sundries on the weld surface can be removed, enabling the ultrasonic wave to penetrate the weld as completely as possible, reducing the detection error.

[0020] 2. In the present utility model, when using an ultrasonic detector, first insert the plug on the connecting wire into the ultrasonic detector, and then slide the positioning frame. The positioning frame slides towards the direction close to the connecting wire. The positioning frame slides with the assistance of the rectangular plate. After the positioning frame slides a certain distance, the mounting pad on the positioning frame presses the plug on the connecting wire. At this time, the plug on the connecting wire is limited on the ultrasonic detector. By setting the limiting structure, when using an ultrasonic detector, the plug on the connecting wire can be limited on the ultrasonic detector, preventing the connecting wire from falling off the ultrasonic detector.

[0026] Refer to Figure 1As shown in the figure, the utility model provides a technical solution: a weld detection device for the production of a hydraulic module, including an ultrasonic detector 1. A connecting wire 2 is slidably connected inside the ultrasonic detector 1. A detection head 3 is electrically connected inside the connecting wire 2. A cleaning structure 4 is arranged on the surface of the detection head 3. By setting the cleaning structure 4, when using the ultrasonic detector 1 to detect the weld quality in the production of the hydraulic module, the sundries on the surface of the weld can be removed, so that the ultrasonic wave can penetrate the weld as completely as possible, reducing the detection error. A limiting structure 5 is arranged on the surface of the ultrasonic detector 1. By setting the limiting structure 5, when using the ultrasonic detector 1, the plug on the connecting wire 2 can be limited on the ultrasonic detector 1, so that the connecting wire 2 will not fall off from the ultrasonic detector 1.

[0027] The following specifically describes the specific settings and functions of its cleaning structure 4 and limiting structure 5.

[0028] Refer to Figure 2 and Figure 4 As shown in the figure, in this embodiment: the cleaning structure 4 includes an airbag 401. The surface of the airbag 401 is fixedly connected to the detection head 3. A connecting pipe 408 is communicated inside the airbag 401. An auxiliary pipe 409 is communicated inside the connecting pipe 408. A filter screen 410 is fixedly installed on the surface of the auxiliary pipe 409. The filter screen 410 can prevent sundries from entering the airbag 401 through the connecting pipe 408 and the auxiliary pipe 409. A clamping plate 407 is fixedly installed on the surface of the detection head 3. Two auxiliary rods 403 are fixedly inserted inside the clamping plate 407. A fixing plate 402 is slidably sleeved on the arc surfaces of the two auxiliary rods 403. The surface of the fixing plate 402 is fixedly connected to the airbag 401. A spring 404 is sleeved on the arc surface of the auxiliary rod 403. The two ends of the spring 404 are respectively fixedly connected to the clamping plate 407 and the fixing plate 402. The fixing plate 402 slides away from the detection head 3 under the elastic force of the spring 404. While the fixing plate 402 slides, it drives the airbag 401 to contract, achieving the effect of assisting in driving the airbag 401 to contract. A first grip 405 is fixedly installed on the surface of the clamping plate 407. A second grip 406 is fixedly installed on the surface of the fixing plate 402. Hold the first grip 405 and the second grip 406 with the hand, so that the second grip 406 and the first grip 405 approach each other. At this time, the second grip 406 drives the fixing plate 402 to move, and the fixing plate 402 drives the airbag 401 to open, so that the airbag 401 inhales gas, achieving the effect of assisting in driving the airbag 401 to open.

[0029] Refer to Figure 2 and Figure 3As shown in the figure, specifically, the limiting structure 5 includes a mounting frame 51. The surface of the mounting frame 51 is fixedly connected to the ultrasonic detector 1. A positioning frame 53 is slidably sleeved on the surface of the mounting frame 51. An installation pad 52 is fixedly installed on the surface of the positioning frame 53, and the installation pad 52 is an elastic pad. A guiding hole 54 is formed on the surface of the mounting frame 51. A rectangular plate 55 is slidably connected to the inner wall of the guiding hole 54. The surface of the rectangular plate 55 is fixedly connected to the positioning frame 53. The positioning frame 53 can slide along the surface of the mounting frame 51 with the assistance of the rectangular plate 55, so that when the positioning frame 53 slides on the surface of the mounting frame 51, the positioning frame 53 cannot slide out of the surface of the mounting frame 51, and at the same time, the positioning frame 53 will not rotate.

[0030] Working principle: When it is necessary to use the ultrasonic detector 1 to detect the weld quality in the production of the hydraulic module, hold the first grip 405 and the second grip 406 by hand, so that the second grip 406 and the first grip 405 approach each other. At this time, the second grip 406 drives the fixing plate 402 to move, and the fixing plate 402 drives the airbag 401 to open, so that the airbag 401 inhales gas. At this time, the detection head 3 can be placed near the weld to be detected. Then release the second grip 406. At this time, the fixing plate 402 loses its fixation. At this time, the fixing plate 402 slides in the direction away from the detection head 3 under the elastic force of the spring 404. While the fixing plate 402 slides, it drives the airbag 401 to contract. During the contraction of the airbag 401, the airbag 401 discharges the gas along the connecting pipe 408 and the auxiliary pipe 409. During the discharge of the gas, the sundries on the weld will be blown off. By setting the cleaning structure 4, when using the ultrasonic detector 1 to detect the weld quality in the production of the hydraulic module, the sundries on the weld surface can be removed, so that the ultrasonic wave can penetrate the weld as completely as possible, reducing the detection error.

[0031] When using the ultrasonic detector 1, first insert the plug on the connecting wire 2 into the ultrasonic detector 1. Then slide the positioning frame 53. The positioning frame 53 slides in the direction close to the connecting wire 2. The positioning frame 53 slides with the assistance of the rectangular plate 55. After the positioning frame 53 slides a certain distance, the installation pad 52 on the positioning frame 53 presses the plug on the connecting wire 2. At this time, the plug on the connecting wire 2 is limited on the ultrasonic detector 1. By setting the limiting structure 5, when using the ultrasonic detector 1, the plug on the connecting wire 2 can be limited on the ultrasonic detector 1, so that the connecting wire 2 will not fall off the ultrasonic detector 1.
