Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pull-out force testing, and specifically relates to a clamping fixture for pull-out force testing. Background Technology
[0002] In many fields such as machinery manufacturing, electronic equipment, and aerospace, the stability of product connections is of paramount importance, and pull-out force testing of connectors such as plugs is a crucial step in ensuring their reliability.
[0003] However, when conducting pull-out force tests on large and complex parts, traditional testing fixtures often struggle to clamp them accurately. Due to the large size of the products, existing fixtures are costly to design and have complex structures, making them difficult to adapt to the testing needs of products of different specifications.
[0004] At the same time, such as Figure 2 As shown, traditional pull-out force test stabilizers often require the design of several positioning posts. During use, the part is placed on the stabilizer, the positioning grooves on the part are aligned with the positioning posts one by one, and the part is fixed to the positioning posts with bolts. The operation is cumbersome and consumes a lot of time and manpower. At the same time, there are high requirements for the accuracy of the production of traditional pull-out force test stabilizers. One pull-out force test stabilizer needs to be designed for each part, resulting in high production costs.
[0005] Therefore, the above problems urgently need to be solved. Utility Model Content
[0006] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a clamping fixture for pull-out force testing. By using a sliding and adjustable movable clamping block in conjunction with a positioning block, the limitation of traditional pull-out force testing requiring bolt fixation is changed, making it more convenient to use. At the same time, for different parts, only the movable clamping block needs to be replaced, without having to replace the entire fixture, thus reducing production costs.
[0007] Technical Solution: To achieve the above objectives, this utility model provides a clamping fixture for pull-out force testing, comprising a base plate, on which positioning components and movable clamping components are respectively provided on the left and right sides; the positioning component includes a first support block and a positioning block; the first support block is erected on the base plate; the positioning block is located on top of the first support block; the movable clamping component includes a second support block and a movable clamping block; the second support block is erected on the base plate, and a sliding groove is provided on the upper part of the second support block; the movable clamping block is located in the sliding groove; the end faces of the positioning block and the movable clamping block opposite to each other are respectively provided with contour clamping slots; the movable clamping block slides in the sliding groove to change its distance from the positioning block, thereby achieving clamping. The movable clamping block slides within the groove, allowing for adjustment of the clamping position to accommodate parts of different sizes. The movable clamping block can also be replaced for different part models, enabling the fixture to adapt to parts of various sizes and shapes, thus improving its versatility and reducing production costs. The contoured clamping slots on the positioning block and movable clamping block are designed according to the shape of the part, ensuring a larger contact area and more stable clamping, reducing damage to the part's surface. The sliding design of the movable clamping block within the groove allows for rapid adjustment of the clamping position, reducing preparation time before testing and thus improving testing efficiency.
[0008] Furthermore, an adjusting screw is provided on the upper part of the slide. The adjusting screw is used to adjust the position of the movable clamping block. After the adjusting screw is tightened, the movable clamping block will be subjected to a downward pressure, so that it cannot move and remains stable.
[0009] Furthermore, the movable clamping block and the positioning block are at the same horizontal height to ensure that the clamping force is on a horizontal plane, thereby ensuring clamping stability.
[0010] Furthermore, the positioning block is fixedly connected to the first support block by a set of bolts. This bolted connection ensures the robustness between the positioning block and the first support block.
[0011] Furthermore, the cross-sectional area of the slide is slightly larger than that of the movable clamping block. The dimensional design of the slide and the movable clamping block ensures smooth movement of the movable clamping block, thereby achieving stable clamping.
[0012] Furthermore, positioning extensions are provided on both lower edges of the positioning block. The positioning extensions ensure further guiding and positioning of the part.
[0013] Furthermore, the lower edges of both sides of the base plate are provided with stabilizing extensions. The stabilizing extensions ensure the stability of the base.
[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0015] 1. This utility model provides a clamping fixture for pull-out force testing. Through the design of a slidingly adjustable movable clamping block and a positioning block, it changes the limitation of traditional pull-out force testing that requires fixing with bolts, making it more convenient to use.
[0016] 2. This utility model provides a clamping fixture for pull-out force testing. For different parts, only the movable clamping block needs to be replaced, without replacing the entire fixture, thus reducing production costs. Attached Figure Description

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example
[0027] In this embodiment, as Figure 1This utility model discloses a clamping fixture for pull-out force testing, including a base plate 1. Positioning components 2 and movable clamping components 3 are respectively provided on the left and right sides of the base plate 1. The positioning components 2 include a first support block 21 and a positioning block 22. The first support block 21 is erected on the base plate 1, and the positioning block 22 is located on top of the first support block 21. The movable clamping component 3 includes a second support block 31 and a movable clamping block 32. The second support block 31 is erected on the base plate 1, and a sliding groove 311 is provided on the upper part of the second support block 31. The movable clamping block 32 is located within the sliding groove 311. Contouring clamping slots 321 are respectively provided on the end faces of the positioning block 22 and the movable clamping block 32. The movable clamping block 32 slides within the sliding groove 311, changing its distance from the positioning block 22, thereby achieving clamping.
[0028] Specifically, the movable clamping block 32 can be inserted and removed along the slide groove 311, and can be replaced for different clamping types of parts; such as Figure 3 and Figure 5 As shown, for the left and right parts of the same component, the movable clamping block 32 can be pulled out for replacement, instead of requiring the entire tooling to be redesigned as with traditional pull-out force test pieces, thus saving production costs.
[0029] In this embodiment, as Figure 1 The upper part of the slide 311 is provided with an adjusting screw 3111.
[0030] Specifically, it is preferable to add a rubber part to the bottom of the adjusting screw 3111. When the adjusting screw 3111 is tightened, its rubber part generates pressure on the upper surface of the movable clamping block 32, so as to prevent the movable clamping block 32 from shifting its position without damaging it, thus ensuring clamping stability.
[0031] In this embodiment, as Figure 1 and Figure 4 The movable clamping block 32 and the positioning block 22 are at the same horizontal height.
[0032] In particular, it is optional to integrate the first support block 21 and the second support block 31 with the base plate 1, thereby avoiding the problem of inconsistent horizontal height due to assembly errors.
[0033] In this embodiment, as Figure 1 and Figure 4 The positioning block 22 is fixedly connected to the first support block 21 by a set of bolts 211.
[0034] In particular, a positioning pin can be added between the positioning block 22 and the first support block 21 to improve the positioning accuracy of the two during assembly.
[0035] In this embodiment, as Figure 1The cross-sectional area of the slide 311 is slightly larger than the cross-sectional area of the movable clamping block 32.
[0036] Specifically, lubricating oil can be periodically applied to the slide groove 311 as an option, which facilitates the adjustment of the movable clamp 32.
[0037] In this embodiment, as Figure 1 The positioning block 22 has positioning extensions 221 on both sides of its lower edge.
[0038] Specifically, the positioning extension 221 is designed according to the shape of the part and fits the shape of the part to achieve positioning guidance.
[0039] In this embodiment, as Figure 1 The bottom plate 1 has a stable extension 11 on both sides of its lower edge.
[0040] Specifically, the base plate 1 can be placed on the frame of the pull-out force test piece, and the test can begin after the part to be tested is clamped.
[0041] The working principle of the above embodiments is as follows:
[0042] This utility model discloses a clamping fixture for pull-out force testing. In use, the movable clamping block 32 is adjusted to a suitable position in the slide groove 311, and the part is placed between the first support block 21 and the second support block 31. The part of the part that needs to be tested for pull-out force is horizontally inserted along the contour clamping slot 321 of the positioning block 22. Then, the movable clamping block 32 is moved horizontally, and the movable clamping block 32 and the contour clamping slot 321 of the positioning block 22 clamp the part to be tested. Finally, the adjusting screw 3111 is tightened to complete the assembly.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
