Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing fixture technology, specifically to an X-ray testing fixture. Background Technology
[0002] X-ray inspection is frequently used to detect surface or internal structural defects in objects, thereby determining the quality of processed products. For mass-produced products such as mobile phone frames, X-ray inspection is often necessary to assess product quality. For such mass production, multiple products are placed in a testing fixture for fixation, and then the fixture is placed into the X-ray inspection device. Current methods for fixing the products typically use cylinders, which hold one end of the product against a positioning element for fixation. However, for the inspection of multiple products, each product requires a separate cylinder, making this method costly. Utility Model Content
[0003] To address the issue of high cost of existing fixtures, this invention provides an X-ray inspection fixture that is suitable for clamping large batches of products, is easy to use, and is less expensive than using cylinders to fix products.
[0004] The technical solution is as follows: An X-ray inspection fixture includes a mounting plate with a product fixing station. The product fixing station is equipped with a positioning element one, a positioning element two, a limiting adjustment block one, and a clamping assembly. The limiting adjustment block one cooperates with the positioning element one to restrict the movement of the product in the width direction. The clamping assembly presses the product onto the positioning element two. The limiting adjustment block one is connected to the mounting plate through an oblong hole extending along the width direction of the product. The clamping assembly includes a limiting adjustment block two, a fixing element, and a spring plunger. The limiting adjustment block two is connected to the mounting plate through an oblong hole extending along the length direction of the product. The spring plunger is mounted on the limiting adjustment block two through the fixing element. Each spring plunger corresponds to one end of the product and contacts the product through an elastic telescopic element. When the product is not clamped, the distance between the end of the elastic telescopic element and the positioning element two is less than the length of the product.
[0005] Furthermore, the limiting adjustment block two is provided with mounting hole one and mounting hole two. Mounting hole one extends along the length direction of the product. The spring plunger is placed in mounting hole one. Mounting hole two communicates with mounting hole one. The fixing member is threadedly connected to mounting hole two. By tightening the fixing member two, one end of it presses against the spring plunger, thereby fixing the spring plunger in mounting hole one.
[0006] Furthermore, the mounting plate includes a base plate and a load-bearing plate. The load-bearing plate is fixed to the base plate. A product fixing groove is formed on the load-bearing plate, which penetrates the load-bearing plate and exposes the area on the base plate for product fixing. Positioning element one is the inner wall of the product fixing groove, and positioning element two is a positioning block fixed to the load-bearing plate. Limiting adjustment block one is located in the product fixing groove and connected to the base plate. One end of the limiting adjustment block two extends into the product fixing groove, and the other end is fixedly connected to the load-bearing plate.
[0007] Furthermore, the product has multiple fixed workstations.
[0008] Furthermore, the spring plunger is a rubber-tipped spring plunger, which contacts the product through a material that prevents scratching the product surface.
[0009] Beneficial effects: This fixture uses a spring plunger to clamp the product, which effectively reduces costs compared to using a cylinder for clamping large batches of products. Moreover, during use, since the distance between the end of the elastic telescopic component and the second positioning component is less than the length of the product, the product can be directly placed into the fixture to achieve clamping in the length direction, which is convenient to use and greatly improves the clamping efficiency for X-ray inspection of large batches of products. At the same time, the limit adjustment blocks one and two are installed through oblong holes, and their positions are adjustable, allowing the fixture to be used for products of various sizes. In addition, by using a material that prevents scratches on the product surface in contact with the product, scratches on the product surface by the fixture can be avoided.

[0014] like Figure 1 , Figure 2An X-ray inspection fixture is shown, comprising a mounting plate with product fixing stations. To accommodate mass production inspections, such as X-ray inspection of mobile phone frames, multiple product fixing stations are provided on the same mounting plate, and each product fixing station is used to fix multiple products 100. Each product fixing station is equipped with a positioning element 1, a positioning element 2, a limiting adjustment block 3, and a clamping assembly 4. The limiting adjustment block 3 cooperates with the positioning element 1 to limit the product 100 in the width direction (…). Figure 1 The limit adjustment block 3 can be made of anti-static POM material, which can effectively protect the product surface and prevent scratches when the limit adjustment block 3 is in direct contact with the product being tested; the pressing component 4 is used to press the product 100 onto the positioning component 2, and the limit adjustment block 3 moves along the width direction of the product 100 through the oblong hole 5 (as shown by the middle arrow B). Figure 3 (As shown) It connects to the mounting plate, and the position of the limiting adjustment block 3 can be easily adjusted through the oblong hole 5. Figure 2 The clamping assembly 4 includes a limit adjustment block 2 401 ( Figure 2 The middle limit adjustment block 401 is transparent and only the wireframe is displayed. The fixing part 402 and the spring plunger 403 are also shown. The middle limit adjustment block 401 is connected to the mounting plate through the waist-shaped hole 5 extending along the length of the product. The waist-shaped hole 5 facilitates the position adjustment of the middle limit adjustment block 401. The spring plunger 403 is installed on the middle limit adjustment block 401 through the fixing part 402. Each spring plunger 403 corresponds to one end of the product 100 and contacts the product through the elastic telescopic part. When the product is not clamped, the distance between the end of the elastic telescopic part and the positioning part 2 is less than the length of the product 100.
[0015] In use, the product placement area is limited by positioning components one and two and limit adjustment block one 3. The user directly places the C-shaped product 100 between the clamping component 4 and positioning component two 2. When the product 100 is inserted, the elastic extension of the spring plunger 403 creates a sufficient insertion area. After the product is inserted, the elastic force of the spring plunger 403 can press the product onto the positioning component two 2, thereby fixing the product 100. It is convenient to use. At the same time, when it is necessary to use products 100 of different sizes, it is only necessary to adjust the position of limit adjustment blocks one and two through the oblong hole 5 to be suitable for products 100 of different sizes. Moreover, since the spring plunger 403 has a stroke, it is not necessary to frequently adjust the limit adjustment blocks when changing to test products of different sizes. Therefore, this fixture is particularly suitable for fixing mobile phone frames (because there are many specifications of mobile phone frames).
[0016] Specific combination Figure 2The limiting adjustment block 401 has a first mounting hole and a second mounting hole. The first mounting hole extends along the length of the product. The spring plunger 403 is inserted into the first mounting hole and threadedly connected to it. The distance of the spring plunger 403 extending out of the limiting adjustment block 401 can be adjusted by controlling the depth to which the spring plunger 403 is screwed into the first mounting hole. The second mounting hole is connected to the first mounting hole. The fixing part 402 is threadedly connected to the second mounting hole. It can be a conventional plunger. By tightening the fixing part 402, one end of it is pressed against the spring plunger 403, thereby effectively fixing the spring plunger 403 in the first mounting hole. In this way, the extension distance of the spring plunger 403 relative to the limiting adjustment block 401 is adjustable.
[0017] The mounting plate specifically includes a base plate 6 and a load-bearing plate 7. The base plate 6 can be made of carbon fiber. The load-bearing plate 7 is fixed to the base plate 6 and has a product fixing groove that penetrates through the load-bearing plate 7 and exposes the area on the base plate 6 used for product fixing. Positioning component 1 is the inner wall of the product fixing groove, and positioning component 2 is a positioning block fixed to the load-bearing plate 7. Limiting adjustment block 3 is located in the product fixing groove and connected to the base plate 6. One end of the limiting adjustment block 401 extends into the product fixing groove, and the other end is fixedly connected to the load-bearing plate 7. The oblong hole 5 connected to the limiting adjustment block 3 is opened in the base plate. On the 6th, the limit adjustment block 3 has a through hole or a threaded hole. The connection between the two can be achieved by passing a bolt through the oblong hole and the through hole and tightening a nut, or by passing a bolt through the oblong hole and threading it into the threaded hole. The limit adjustment block 401 has an oblong hole, and the load-bearing plate 7 has a through hole or a threaded hole. The two can be connected in the above ways. When adjustment is needed, simply loosen the bolt or nut to adjust the position of the limit adjustment block 3 along the width direction of the product 100 and adjust the position of the limit adjustment block 401 along the length direction of the product 100.
[0018] In addition, to avoid scratching the product surface, spring plunger 403 is a rubber-tipped spring plunger. The rubber-tipped spring plunger contacts the product through a material that prevents scratching the product surface (e.g., the end of spring plunger 403 is made of soft plastic). Spring plunger 403 is an existing component and can be used... Figure 4 The structure shown specifically includes a housing 101, a spring 102, and a contact head 103. The spring 102 is located inside the hollow housing 101. One end of the contact head 103 is located inside the housing 101 and contacts the spring 102, while the other end extends out of the housing 101 to contact the product 100. The contact head 103 can be as follows: Figure 4The shown head can also be a ball bearing, which can be made of plastic or other wear-resistant materials to provide good durability. Taking the ball bearing as an example, when the product is inserted and an external force is applied to the contact head 103, the ball will overcome the preload of the spring and move into the housing 101. The elastic force will press the product, keeping the product 100 stable during movement. The rubber head contacts the product, protecting the product's appearance from damage. When the product is removed and the external force disappears, the preload of the spring will cause the ball to return to its original position.
