Description

Technical Field

[0001] The utility model relates to the technical field of structural tolerance inspection, in particular to an inspection tooling fixture. Background Art

[0002] The heat dissipation module of a notebook computer plays an important role in heat dissipation in the whole system. In a limited space, it is particularly important to design a module structure with a compact structure, light weight and strong heat dissipation capacity. The new heat dissipation module needs to be inspected for its structure and appearance, mainly to check the integrity of the outer shape structure at various parts of the module, whether the positioning positions of screw holes and other dimensions meet the standards, whether there are any missing attachments, and whether the flatness and other parameters at the key positions of the whole module meet the requirements, so as to ensure the quality of the whole machine.

[0003] However, when the heat dissipation module is designed to be relatively compact and the dimensional position is relatively extreme, and the position tolerance of the heat pipe is poorly controlled, the heat pipe may leak out in some whole machines, that is, the heat pipe can be visually seen at the air outlet. When neither the housing structure nor the heat dissipation module design can be changed, in order to prevent whole machines with poor appearance due to heat pipe leakage from entering the market, it is necessary to start from the structural inspection of the heat dissipation module itself. For example, control the dimensional tolerance during the heat pipe welding process, and use an inspection fixture to avoid modules in which the dimensional tolerance of the heat pipe during production causes the position of the heat pipe to exceed the limit distance, so as to avoid losses to the whole machine during online production.

[0004] For the above problems, the existing solution is: use an inspection fixture to check whether the position of the heat pipe exceeds the designed position. The inspection fixture includes an inspection pressing block and a pressing block limit clamping part. The inspection pressing block is columnar, one end of which is rotatably connected, and the other end is used to connect with the pressing block limit clamping part. During detection, place the heat pipe under the inspection pressing block, and judge whether there is interference with the heat pipe when the inspection pressing block is in a horizontal state. Among them, the size of the space under the inspection pressing block is preset. Lower the inspection pressing block until the head of the inspection pressing block enters the pressing block limit clamping part. When the inspection pressing block can be completely inserted into the pressing block limit clamping part and their surfaces are flush, it is considered that the size of the heat pipe is qualified, otherwise, it is judged as unqualified.

[0005] The disadvantages of this inspection method are as follows: Whether it is qualified or not needs to be inspected by the naked eye of the operator. During the actual inspection operation, the operator places the fixture on the workbench for inspection. When looking down, there will be a visual error in judging whether the planes are consistent due to the oblique view. In addition, different inspectors may have certain differences in judgment criteria, which may lead to misjudgment, allowing some defective products to pass the inspection as qualified products. Moreover, when the heat pipe exceeds the limit, the original inspection block cannot be fully inserted into the block limit clamping part. However, due to the negligence of the inspector during the operation, if the inspector presses the inspection block forcefully, the inspection block will already press on the edge of the heat pipe, causing the fan end of the module to tilt slightly. However, since the tilting amplitude is small, it is easy for the inspector to overlook, resulting in misjudgment. Utility Model Content

[0034] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] An inspection tooling fixture provided by an embodiment of the present utility model includes a base and an inspection assembly; the inspection assembly is arranged on the base, and among them, the inspection assembly determines whether the tooling to be detected is qualified by sliding a detection block.

[0036] The following will describe in detail each component, the connection relationship and the position relationship among the components in the inspection tooling fixture provided by the embodiment of the present utility model with reference to the accompanying drawings.

[0037] As Figures 1 to 6 shown, the base 10 includes a mounting position, and the tooling to be detected and the inspection assembly 20 are respectively arranged on the mounting position; for example, a profiling groove 11 having the same contour shape as the tooling to be detected is provided on the mounting position; the tooling to be detected is arranged in the profiling groove 11.

[0038] Select the corresponding base 10 according to different toolings to be detected. Among them, a profiling groove 11 is provided on the base 10, and the profiling groove 11 can better match the tooling to be detected, which is beneficial to the tooling to be detected being installed in the correct inspection position.

[0039] In an embodiment of the present utility model, the inspection assembly 20 includes a guide rod 21 and a detection block 22. The detection block 22 is sleeved on the guide rod 21 and is slidably connected to the guide rod 21. The guide rod 21 and the detection block 22 are located on one side of the mounting position, and the side of the detection block 22 facing the tooling to be detected is the detection end; the detection block 22 is used to slide between the head and the tail ends of the guide rod 21, or during the sliding process of the detection block 22, the detection end is used to contact the tooling to be detected to generate interference.

[0040] During the sliding process of the detection block 22, whether there is interference with the product to be detected is determined to determine whether the product to be detected is a qualified product. Among them, the position of the inspection component 20 on the base 10 is fixed, and the position of the tooling to be detected on the base 10 is also fixed. Under normal circumstances, if the product to be detected is a qualified product, the detection block 22 will not contact it when sliding. On the contrary, if there is a dimensional deviation in the product to be detected, the detection block 22 will contact the product to be detected when sliding.

[0041] Based on this, after the tooling to be inspected is installed in place, the inspection block 22 is reset, and the staff manually moves the inspection block 22. If the inspection block 22 interferes with the tooling to be inspected, it means that the current tooling to be inspected is an unqualified product. On the contrary, if the inspection block 22 does not interfere with the tooling to be inspected, it means that the current tooling to be inspected is a qualified product.

[0042] For example, the inspection component 20 also includes a first bracket 23 and a second bracket 24, which are respectively fixedly connected to the surface of the base 10; one end of the guide rod 21 is rotatably connected to the first bracket 23, and the second bracket 24 is provided with a card interface 241, and the other end of the guide rod 21 is used to be carded with the card interface 241, and the guide rod 21 is parallel to the surface of the base 10.

[0043] The other end of the guide rod 21 is detachably connected to the card interface 241 of the second bracket 24. When installing the tooling to be detected, the guide rod 21 can be rotated and separated from the second bracket 24. At this time, there is no guide rod 21 blocking between the first bracket 23 and the second bracket 24, and the tooling to be detected can be installed normally.

[0044] After installation, the other end of the guide rod 21 is connected to the card interface 241 of the second bracket 24. After connection, the guide rod 21 is parallel to the surface of the base 10. For example, the cross-sectional shape of the guide rod 21 is non-circular; for example, the cross-sectional shape is rectangular. The detection block 22 is in the shape of a rectangular parallelepiped, and a through hole having the same cross-sectional shape as the guide rod 21 is provided on the detection block 22. One side of the detection block 22 is the detection end. With a structure having a non-circular cross-section, the detection block 22 will not rotate relative to the guide rod 21, thereby ensuring the accuracy of the detection end during testing.

[0045] Continue to refer Figures 1 to 6 As shown, in the embodiment of the utility model, in order to prevent the tooling to be detected from lifting during detection, a fixing structure 30 can also be configured to fix the tooling to be detected using the fixing structure 30. Specifically: the fixing structure 30 is located on one side of the installation position and is used to press the tooling to be detected on the installation position; the side where the fixing structure 30 is located is the opposite side of the guide rod 21 and the detection block 22.

[0046] If the tooling to be detected warps, the end where the guide rod 21 and the detection block 22 are located is the force application end, and warping will occur on the opposite side of this end. Therefore, it is necessary to fix the opposite side of the detection tooling. For example, the fixing structure 30 includes a first slide rail 31, a first slider 32, and a first pressing block 33. The first slider 32 is slidably connected to the first slide rail 31. The first pressing block 33 is provided at the top of the first slider 32, and the first pressing block 33 includes a pressing portion 34 extending outside the first slider 32. If the pressing portion 34 is plate-shaped, a rubber buffer layer is provided on the pressing side. The first slider 32 slides on the first slide rail 31 towards the tooling to be detected, and the pressing portion 34 slides above the tooling to be detected, and the tooling to be detected is limited in the direction perpendicular to the surface of the base 10 through the pressing portion 34. Conversely, the first slider 32 slides on the first slide rail 31 in the direction away from the tooling to be detected, and the pressing portion 34 moves in the opposite direction to release the limitation on the tooling to be detected.

[0047] Continue to refer to Figures 1 to 6 As shown, in the embodiment of the present utility model, the jig further includes a plurality of positioning and detection pressing blocks 40, and the plurality of positioning and detection pressing blocks 40 are located outside the installation position; and further includes a pressing head structure 50. Before the detection operation, it is necessary to position and detect the tooling to be detected through the positioning and detection pressing blocks 40 and the pressing head structure 50.

[0048] For example, the pressing head structure 50 includes a lifting member 51 and a pressing head 52; the tooling to be detected is pressed onto the installation position through the pressing head 52. The lifting member 51 includes a vertical plate and a pressing rod. The vertical plate is connected to the surface of the base 10, and a pressing rod is provided on the vertical plate. One end of the pressing rod is connected to the pressing head 52, and the position of the pressing head 52 is adjusted by lifting the pressing rod, and the pressing head 52 can press on the surface of the tooling to be detected.

[0049] For example, the positioning and detection pressing block 40 includes a second slide rail 41, a second slider 42, and a second pressing block 43. The second slider 42 is slidably connected to the second slide rail 41. The second pressing block 43 is provided at the top of the second slider 42, and the second pressing block 43 includes two elastic pieces 44 extending outside the second slider 42. The two elastic pieces 44 are parallel and spaced apart; the second slider 42 is used to slide along the second slide rail 41 and drive the two elastic pieces 44 to position the tooling to be detected.

[0050] The distance between the two elastic pieces 44 is related to the width of the component to be detected. When the tooling to be detected is accurately positioned, the two elastic pieces 44 just extend to both sides of the component. If there is a deviation in the positioning of the tooling to be detected, the elastic pieces 44 will abut against the component and deform. At this time, it is necessary to adjust the tooling to be detected to the correct position, and then perform subsequent inspection operations.

[0051] Such as Figures 1 to 6As shown in the figure, the inspection tooling fixture provided by the embodiment of the present utility model can be used for the detection of the heat dissipation module 60. Among them, the detected heat dissipation module 60 includes a heat dissipation fan 61 and a heat pipe 62. The heat pipe 62 is located on one side of the air outlet of the heat dissipation fan 61, and the detection end is located on one side of the heat pipe 62; the detection block 22 is used to slide between the head and the tail ends of the guide rod 21, or during the sliding of the detection block 22, the detection end is used to contact the heat pipe 62 to generate interference.

[0052] The end of the heat pipe 62 is a tip, and the distance from this position to the detection block 22 is relatively large, which can be used as the starting point of the detection block 22. As the detection block 22 slides, if there is a large tolerance in the connection between the heat pipe 62 and the heat dissipation fan 61, the detection block 22 will interfere with the heat pipe 62, that is, there will be friction between the two, so that it can be determined that the heat dissipation module 60 is a non-conforming product. On the contrary, it can be judged as a qualified product.

[0053] The inspection tooling fixture provided by the present utility model does not require manual visual judgment during inspection, which can reduce the situation of misdetection, and moreover, this fixture can improve the inspection efficiency.
