Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically to a testing fixture for lifting and lowering water circulation. Background Technology

[0002] Looking at the development history of ultrasonic testing technology, early ultrasonic testing was mainly contact testing, which requires a high degree of coupling between the probe and the workpiece surface. However, in practical applications, many workpiece surfaces are complex curved surfaces or relatively rough, making it difficult for contact probes to ensure that ultrasonic waves can effectively penetrate into the workpiece.

[0003] Regarding material properties, it has been found that water has relatively low attenuation of ultrasonic waves and allows the probe and workpiece surface to fit tightly together, forming a good acoustic path. This makes ultrasonic testing using water as a medium possible, and thus water immersion testing fixtures have emerged.

[0004] Meanwhile, with the development of industrial automation and precision manufacturing, the requirements for the accuracy and efficiency of detecting minute internal defects in workpieces have increased significantly. Existing ultrasonic immersion testing fixtures can easily control parameters such as the distance and angle between the probe and the workpiece, enabling efficient and accurate batch testing in conjunction with automated equipment to meet the quality control needs of industrial production.

[0005] With the iterative updates of products and technologies, the frequency of use of water immersion testing fixtures has gradually increased. A typical testing fixture includes a water tank, a lifting platform within the tank to support the workpiece, and a testing probe located beside the tank. During use, the lifting platform moves the workpiece up and down, realizing the process of immersion and removal from the liquid surface. However, during this use, technicians have discovered related problems, such as the corrosion and oxidation of the metal lifting platform in water. This problem causes fine particles to be suspended in the water, which can easily enter the lifting mechanism of the platform, leading to instability and a shortened lifespan, significantly affecting the workpiece testing process. If the lifting platform is simply placed outside the water tank and above it, i.e., the lifting platform and the water tank are arranged vertically, the vertical space occupied by the entire testing fixture will increase due to the size of the lifting platform itself. Consequently, the factory area will need to be large enough to accommodate this large testing fixture. However, factory areas are generally constructed with a pre-defined structure. If complex and cumbersome expansion functions are made to accommodate this testing fixture, the cost will be high, and it will be difficult to restore it to its original state later. In addition, it will also restrict the workers' operating space.

[0006] To address these issues, we propose a lifting and lowering water circulation detection fixture. Utility Model Content

[0007] The purpose of this utility model is to solve the problems in the prior art by proposing a lifting water circulation detection fixture. This detection fixture reduces the space occupied by the lifting component by setting the lifting component next to the water tank. At the same time, by setting a bearing component adapted to the lifting component, the bearing component can drive the product in and out of the water tank.

[0008] To solve the above problems, this utility model provides the following technical solution:

[0009] The lifting water circulation testing fixture includes a water tank, an ultrasonic probe, a lifting assembly located beside the water tank, and a load-bearing assembly that moves vertically. The load-bearing assembly has a connecting plate and a load-bearing plate connected to the connecting plate. The lifting assembly is used to drive the connecting plate to move vertically, and the vertical downward movement endpoint of the connecting plate is lower than the plane position of the top of the water tank. The load-bearing plate is used for placing workpieces, and a clearance area is provided between the connecting plate and the load-bearing plate so that when the lifting assembly drives the connecting plate to the vertical downward movement endpoint, the clearance area is fitted onto one side of the water tank, and the load-bearing plate is placed inside the water tank.

[0010] As a further embodiment of this utility model: the bearing component further includes a U-shaped adapter plate, the opening of the U-shaped adapter plate forming the clearance area, and the two ends of the U-shaped adapter plate are respectively used for the installation of the connecting plate and the bearing plate.

[0011] As a further embodiment of this utility model: both the connecting plate and the bearing plate are arranged horizontally and are coplanar.

[0012] As a further embodiment of this utility model: the lifting assembly includes a base plate located next to the water tank, a plurality of guide rods for the connecting plate to be movably mounted on the base plate, and the guide rods are arranged in the vertical direction. A drive source is provided at the bottom of the base plate, and the execution end of the drive source is fixedly assembled with the connecting plate.

[0013] As a further embodiment of this utility model: the guide rod is provided as three rods, and the three guide rods are arranged in a triangular shape.

[0014] As a further embodiment of this utility model: the lifting assembly also includes a positioning plate arranged in a triangular shape, and the three ends of the triangular positioning plate are respectively fixedly connected to the top of the three guide rods.

[0015] As a further embodiment of this utility model: the bearing plate is provided with a clamping member, and the actuating end of the clamping member can move toward or away from the bearing plate, forming an adjustable clamping area between the actuating end and the bearing plate.

[0016] As a further embodiment of this utility model, the support plate is provided with a plurality of perforations.

[0017] As a further embodiment of this utility model, the testing fixture also includes a filtration assembly, which includes a connecting cavity located inside the water tank, a centrifugal pump located on the connecting cavity, and a filter located outside the water tank. The inlet and outlet of the filter are connected to the connecting cavity and the water tank respectively via pipes.

[0018] As a further embodiment of this utility model: the U-shaped adapter plate is provided with a reinforcing rib plate that is connected to the connecting plate and the bearing plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By arranging the lifting component adjacent to the water tank, so that part or all of the lifting component is located below the plane of the top of the water tank, compared with the prior art design that places the lifting mechanism above the water tank, the layout design of this application can reduce the volume occupied by the lifting component in three-dimensional space. Moreover, by setting a bearing component to cooperate with it, the vertical lifting and precise positioning of the workpiece can be realized. The design of the avoidance area allows the bearing plate to enter the water tank smoothly, which is convenient for the workpiece to be inspected in the water tank. The operation is flexible and efficient.

[0021] 2. The design of the U-shaped adapter plate further optimizes the structure of the load-bearing components. The clearance area formed by its opening not only simplifies the installation process but also enhances the overall stability, ensuring a more secure connection between the connecting plate and the load-bearing plate and improving the reliability of the tooling.

[0022] 3. The connecting plate and the bearing plate are arranged horizontally and in the same plane, which can ensure that the workpiece remains horizontal during the lifting process, avoid detection errors caused by tilting, and simplify the structural design, making it easier to install and maintain.

[0023] 4. The lifting assembly adopts a combination of guide rods and drive source, which can realize the smooth lifting of the connecting plate. The arrangement of the guide rods ensures the accuracy and stability of the movement, and the direct connection of the drive source further improves the lifting efficiency. The overall structure is simple and easy to control.

[0024] 5. The advantage of the three guide rods arranged in a triangular shape is that they can distribute the force evenly, enhance the stability of the lifting process, avoid swaying or deviation caused by uneven force at a single point, and ensure that the workpiece remains stable during the lifting process.

[0025] 6. The clamping mechanism ensures that the workpiece is firmly fixed on the support plate, preventing the results from being affected by workpiece movement during the inspection process. The adjustable size of the clamping area can accommodate workpieces of different sizes, improving the versatility and practicality of the tooling.

[0026] 7. The evenly distributed drainage holes on the support plate can not only effectively drain water, but also reduce weight, simplify the cleaning process, and improve the convenience of testing and the durability of the tooling.

[0027] 8. The design of the filter assembly, through the cooperation of centrifugal pump and filter, can circulate and filter the water in the water tank, ensuring water quality cleanliness, avoiding interference from impurities on test results, extending the service life of the water tank, and reducing maintenance costs.

[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-4 As shown, the lifting water circulation testing fixture includes a frame, on which a water tank 1 and a robotic arm are mounted. The robotic arm is equipped with an ultrasonic probe 8 for testing the products inside the water tank 1. Simultaneously, a lifting assembly 2 and a load-bearing assembly 3 are also mounted on the frame. Both the lifting assembly 2 and the water tank 1 are located on the same horizontal plane on the frame.

[0036] The lifting assembly 2 includes a base plate 201 located beside the water tank 1. The base plate 201 is coplanar with the bottom of the water tank 1. Several guide rods 202 (preferably three, arranged in a triangular shape) are provided on the base plate 201, and the guide rods 202 are arranged vertically. A drive source 203 is provided at the bottom of the base plate 201. The bearing assembly 3 is movably mounted on the guide rods 202, and the actuator of the drive source 203 is used to drive the bearing assembly 3 to move vertically. Thus, when the bearing assembly 3 is in a high position, the product can be placed on it, and then the bearing assembly 3 is driven down to a low position inside the water tank 1 to realize subsequent testing.

[0037] This layout design, in which the lifting component 2 and the water tank 1 are on the same plane, ensures that part or all of the lifting component 2 is not higher than the plane at the top of the water tank 1. Compared with the existing technology where the lifting mechanism is located above the water tank 1, the layout of this application results in the lifting component 2 occupying less space in three-dimensional space and does not restrict the operator's operating space.

[0038] To enable the lifting assembly 2 and the water tank 1 to function in this layout, the supporting assembly 3 is as follows:

[0039] The load-bearing component 3 includes a connecting plate 301, a load-bearing plate 302, and a U-shaped adapter plate 303, such as Figures 2-3 As shown, the opening of the U-shaped adapter plate 303 faces downward. Both ends of the U-shaped adapter plate 303 are fixedly connected to the connecting plate 301 and the bearing plate 302, respectively. Both ends of the U-shaped adapter plate 303 are provided with reinforcing ribs 7 connected to the connecting plate 301 and the bearing plate 302. The connecting plate 301 and the bearing plate 302 are both horizontally arranged and coplanar. The connecting plate 301 is movably mounted on the guide rod 202 and fixedly connected to the execution end of the drive source 203. The endpoint of the vertical movement of the connecting plate 301 is lower than the plane where the top of the water tank 1 is located. The opening of the U-shaped adapter plate 303 forms a clearance area 304. Therefore, when the lifting component 2 drives the connecting plate 301 to move vertically downward to the endpoint, the clearance area 304 will be sleeved on one side of the water tank 1, and the bearing plate 302 will drive the product to be placed inside the water tank 1.

[0040] In use, the drive source 203 can move the connecting plate 301 up and down, and the carrier plate 302 will move accordingly. When the carrier plate 302 is in a high position, the product can be placed on the carrier plate 302. Then, the drive source 203 drives the connecting plate 301 to move down until the carrier plate 302 moves the product down into the water tank 1. This state can be controlled by... Figure 2 This is to be represented. In this process, the U-shaped adapter plate 303, connecting plate 301 and bearing plate 302 are set to adapt to this layout design of the lifting component 2 and the water tank 1, which can reduce the three-dimensional space occupied by the lifting component 2, and also drive the product to make corresponding vertical movements, making it convenient to use.

[0041] When the guide rods 202 are designed to have three members, in order to prevent the connecting plate 301 from moving out of the guide rods 202, the lifting assembly 2 also includes a positioning plate 204 arranged in a triangular shape, and the three ends of the triangular positioning plate 204 are fixedly connected to the top of the three guide rods 202 respectively. At the same time, in order to ensure the stability of the connecting plate 301 when it descends to the end point, a shock absorber or the like can be installed on the base plate 201.

[0042] like Figure 3 As shown, to ensure stable placement of the product on the support plate 302, a clamping member 4 can be provided on the support plate 302. The actuating ends of the clamping member 4 can move towards or away from the support plate 302, forming an adjustable clamping area between the actuating ends and the support plate 302. The product can be placed on this clamping area for fixation. Simultaneously, to prevent the support plate 302 from carrying away water from the water tank 1 during its upward movement, multiple leakage holes 5 are evenly distributed on the support plate 302.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, furthermore, in order to prevent waste debris in the water tank 1 from affecting the detection, this application also includes a filter assembly 6. The filter assembly 6 includes a connecting cavity 601 disposed in the water tank 1, a centrifugal pump 602 disposed on the connecting cavity 601, and a filter 603 (preferably a PP filter) disposed outside the water tank 1. The inlet and outlet of the filter 603 are connected to the connecting cavity 601 and the water tank 1 respectively through pipes 604. During the detection process, the filter assembly 6 will work continuously. Specifically, the centrifugal pump 602 pumps water from the water tank 1 into the connecting cavity 601. The connecting cavity 601 transports the water to the filter 603 through the pipe 604. After the filter 603 filters the water, it transports the water back to the water tank 1 through the pipe 604 at its outlet, thus realizing the water filtration cycle.

[0044] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
