Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a testing device for twisted needles. Background Technology

[0002] Twist pins are a critical component of connectors, and their dimensional accuracy is crucial to the performance of the final product. Ensuring the outer diameter of the twist pins meets specifications is a key step in guaranteeing product quality during production. However, due to the small size of twist pins, traditional manual measurement and screening methods are not only inefficient but also difficult to guarantee accuracy.

[0003] like Figure 1 As shown, the existing inspection fixture 100 includes a fixture body 110 and three locking elements 120. The fixture body 110 is locked by the three locking elements 120 to form a detection groove 130 for detecting the outer diameter of twisted needles. The inspection fixture 100 mainly uses a three-point locking method to adjust the gap of the detection groove 130 to detect the outer diameter of twisted needles. Although this three-point locking method can provide uniform pressure and a good locking effect, when used for screening the outer diameter of twisted needles, the consistency of the gap size of the detection groove 130 is low, resulting in a decrease in the accuracy of detecting the outer diameter of twisted needles. This reduces the reliability of the inspection fixture 100 and increases production costs. Utility Model Content

[0004] This application mainly provides an inspection device for twisted needles, which solves the problem of low consistency in the gap size of various parts of the inspection groove.

[0005] This application provides a testing device for twisted needles, comprising:

[0008] A clamping assembly is disposed within the accommodating space. The clamping assembly abuts against the first positioning member or the second positioning member and is used to apply pressure to the first positioning member or the second positioning member to adjust the distance between the first positioning member and the second positioning member.

[0009] The inspection device includes at least one spacer disposed between the first positioning member and the second positioning member, for adjusting the distance between the first positioning member and the second positioning member.

[0010] The clamping assembly includes at least one locking member and a clamping member, wherein the clamping member abuts against the first positioning member or the second positioning member, and the locking member is used to apply pressure to the clamping member.

[0011] The spacer is provided in correspondence with the locking member.

[0012] The clamping member has a groove on the side away from the locking member, and a portion of the first positioning member or the second positioning member is disposed in the groove so that the clamping member abuts against the first positioning member or the second positioning member.

[0013] The main body has at least one locking hole on the side away from the first or second positioning member, and the locking member passes through the locking hole and abuts against the pressing member.

[0014] Wherein, the at least one spacer is three spacers, the at least one locking member is three locking members, the three spacers are spaced apart along the length direction of the main body, and each locking member is located above the corresponding spacer.

[0015] Wherein, the first positioning element includes a first roller, and the second positioning element includes a second roller;

[0016] The first roller abuts against the pressing assembly, and the second roller is located between the first roller and the inner wall of the main body;

[0017] Alternatively, the second roller abuts against the pressing assembly, and the first roller is located between the second roller and the inner wall of the body.

[0018] The main body is provided with a material discharge chute, which is correspondingly provided with the inspection chute.

[0019] The main body has an opening on its side wall, which communicates with the accommodating space. The first positioning member, the second positioning member, and the clamping assembly are disposed in the accommodating space through the opening.

[0020] The beneficial effects of this application are as follows: The inspection device of this application includes a main body, a first positioning member, a second positioning member, and a clamping assembly. The main body has an accommodating space, and the first positioning member, the second positioning member, and the clamping assembly are disposed within the accommodating space. The first positioning member and the second positioning member are spaced apart to form an inspection groove, which is used to screen twisted needles. The clamping assembly abuts against the first positioning member or the second positioning member to apply pressure to the first positioning member or the second positioning member, thereby adjusting the distance between the first positioning member and the second positioning member. This application adjusts the distance between the first positioning member and the second positioning member by applying pressure to the first positioning member or the second positioning member through the clamping assembly, that is, by adjusting the gap size of the inspection groove through the clamping assembly, enabling the inspection of twisted needles with different outer diameters. The abutment between the clamping assembly and the first positioning member or the second positioning member increases the contact area between the clamping assembly and the first positioning member or the second positioning member, thereby improving the consistency of the gap size of the inspection groove, improving the accuracy of inspecting twisted needles, thereby improving the reliability of the inspection device and reducing production costs.

[0033] See Figure 1 As shown, Figure 1This is a schematic diagram of an embodiment of an existing inspection fixture. The inspection fixture 100 of this embodiment includes a fixture body 110 and three locking members 120. The fixture body 110 is locked by the three locking members 120 to form a detection groove 130 for detecting the outer diameter of a twisted needle.

[0034] The inspection fixture 100 mainly uses a three-point locking method to adjust the gap of the detection groove 130 to detect the outer diameter of the twisted needle. Although this three-point locking method can provide uniform pressure and a good locking effect, when used for screening the outer diameter of twisted needles, the consistency of the gap size of the detection groove 130 is low, which reduces the accuracy of the inspection of the outer diameter of the twisted needle, thereby reducing the reliability of the inspection fixture 100 and increasing the production cost.

[0035] This application provides a device for testing twisted needles; please refer to [link / reference]. Figures 2-3 As shown, Figure 2 This is a schematic diagram of the structure of an embodiment of the testing device provided in this application; Figure 3 yes Figure 2 An exploded structural diagram of the inspection device. The inspection device 1 in this embodiment includes a main body 10, a first positioning member 20, a second positioning member 30, and a clamping assembly 40; the inspection device 1 in this embodiment is used to detect the outer diameter of twisted needles in order to screen twisted needles.

[0036] The main body 10 has a receiving space, and the first positioning member 20 and the second positioning member 30 are disposed within the receiving space. For example, the receiving space is formed by the hollow structure of the main body 10, wherein the receiving space can be disposed along the length direction of the main body 10. In other embodiments, the receiving space is disposed along the width direction of the main body 10.

[0037] The first positioning element 20 and the second positioning element 30 are spaced apart to form an inspection groove 50, that is, the gap between the first positioning element 20 and the second positioning element 30 forms the inspection groove 50; the inspection groove 50 is used to screen twisted needles to detect the outer diameter of the twisted needles. For example, if the outer diameter of the twisted needle is less than or equal to the gap size of the inspection groove 50, the corresponding twisted needle passes through the inspection groove 50.

[0038] In some embodiments, the installation methods in which the first positioning member 20 and the second positioning member 30 are installed in the accommodating space of the main body 10 include, but are not limited to, embedding, snapping, or inserting.

[0039] The clamping assembly 40 is disposed within the accommodating space and abuts against the first positioning member 20 or the second positioning member 30 to apply pressure to the first positioning member 20 or the second positioning member 30 in order to adjust the distance between the first positioning member 20 and the second positioning member 30.

[0040] In some embodiments, the first positioning member 20 and the second positioning member 30 are first disposed at a distance within the accommodating space, and then the pressing assembly 40 is disposed within the accommodating space, with the pressing assembly 40 abutting against the first positioning member 20. Figure 2 As shown; at this time, the clamping assembly 40 applies pressure to the first positioning member 20 and adjusts the distance between the first positioning member 20 and the second positioning member 30 to adjust the gap size of the inspection groove 50 formed by the first positioning member 20 and the second positioning member 30.

[0041] In some embodiments, the first positioning member 20 and the second positioning member 30 are first disposed at a distance within the accommodating space, and then the pressing assembly 40 is disposed within the accommodating space, with the pressing assembly 40 abutting against the second positioning member 30; at this time, the pressing assembly 40 applies pressure to the second positioning member 30, adjusting the distance between the second positioning member 30 and the first positioning member 20, so as to adjust the gap size of the inspection groove 50 formed by the first positioning member 20 and the second positioning member 30.

[0042] In this embodiment, the clamping assembly 40 applies pressure to the first positioning member 20 or the second positioning member 30, thereby adjusting the distance between the first positioning member 20 and the second positioning member 30. In other words, the clamping assembly 40 can adjust the distance between the first positioning member 20 and the second positioning member 30, thus adjusting the gap size of the inspection groove 50. This allows for the inspection of twisted needles with different outer diameters. The clamping assembly 40 abuts against the first positioning member 20 or the second positioning member 30, increasing the contact area between them. This improves the consistency of the gap size of the inspection groove 50, enhances the accuracy of inspecting twisted needles, improves the reliability of the inspection device 1, and reduces production costs.

[0043] According to some embodiments of this application, such as Figure 2 and Figure 3 As shown, the inspection device 1 of this embodiment includes at least one spacer 60. The spacer 60 includes, but is not limited to, a pad.

[0044] The spacer 60 is disposed between the first positioning member 20 and the second positioning member 30 to adjust the distance between the first positioning member 20 and the second positioning member 30.

[0045] In some embodiments, a first positioning member 20, a second positioning member 30, and a spacer 60 are disposed within an accommodating space, with the spacer 60 located between the first positioning member 20 and the second positioning member 30. A pressing assembly 40 is disposed within the accommodating space and abuts against either the first positioning member 20 or the second positioning member 30. The pressing assembly 40 applies pressure to the first positioning member 20 or the second positioning member 30, and the spacer 60 contacts the first positioning member 20 and the second positioning member 30 respectively, allowing adjustment of the distance between the first positioning member 20 and the second positioning member 30.

[0046] The distance between the first positioning member 20 and the second positioning member 30 is determined by the thickness of the spacer 60; that is, the thickness of the spacer 60 is equal to the gap size of the inspection groove 50 formed by the first positioning member 20 and the second positioning member 30. In other embodiments, by replacing the spacer 60 with different thicknesses, the distance between the first positioning member 20 and the second positioning member 30 can be adjusted so that twisted needles of different outer diameters can pass through the inspection groove 50 for screening.

[0047] In some embodiments, the spacer 60 is made of a rigid material, including but not limited to steel, aluminum alloy, or titanium alloy. Since non-rigid materials are prone to deformation under external forces, the stability of the inspection groove 50 decreases, and unpredictable deformation can easily occur during the inspection process, thereby increasing inspection errors and reducing the reliability of the inspection results. In this embodiment, the spacer 60 is made of a rigid material, which is less prone to deformation, providing higher structural rigidity and enhancing the stability and deformation resistance of the inspection groove 50.

[0048] In this embodiment, at least one spacer 60 is disposed between the first positioning member 20 and the second positioning member 30, which can enhance the structural stability between the first positioning member 20 and the second positioning member 30, that is, enhance the stability of the inspection groove 50 and improve the consistency of the gap size of the inspection groove 50 during long-term use.

[0049] According to some embodiments of this application, the clamping assembly 40 includes at least one locking member 42 and a clamping member 41. The locking member 42 includes, but is not limited to, a screw or a pin; the clamping member 41 includes, but is not limited to, a clamping block.

[0050] The clamping member 41 abuts against the first positioning member 20 or the second positioning member 30, and the locking member 42 is used to apply pressure to the clamping member 41.

[0051] In some embodiments, the clamping member 41 abuts against the first positioning member 20, and the locking member 42 applies pressure to the clamping member 41 so that the clamping member 41 applies pressure to the first positioning member 20 to adjust the distance between the first positioning member 20 and the second positioning member 30.

[0052] In some embodiments, the clamping member 41 abuts against the second positioning member 30, and the locking member 42 applies pressure to the clamping member 41 so that the clamping member 41 applies pressure to the second positioning member 30 to adjust the distance between the first positioning member 20 and the second positioning member 30.

[0053] In this embodiment, the locking member 42 and the pressing member 41 cooperate to apply pressure to the pressing member 41 through the locking member 42, thereby enabling the pressing member 41 to apply pressure to the first positioning member 20 or the second positioning member 30, and adjusting the distance between the first positioning member 20 and the second positioning member 30.

[0054] According to some embodiments of this application, the spacer 60 is correspondingly provided with the locking member 42.

[0055] In some embodiments, the inspection device 1 includes a spacer 60 disposed between the first positioning member 20 and the second positioning member 30, and the clamping assembly 40 includes a locking member 42; in this case, the locking member 42 is disposed on the side of the clamping member 41 away from the first positioning member 20 or the second positioning member 30, and the locking member 42 is located directly above the spacer 60, so that the spacer 60 and the locking member 42 are correspondingly disposed.

[0056] In some embodiments, the inspection device 1 includes two spacers 60, which are respectively disposed at both ends between the first positioning member 20 and the second positioning member 30. The clamping assembly 40 includes two locking members 42. In this case, the two locking members 42 are respectively disposed at both ends on the side of the clamping member 41 away from the first positioning member 20 or the second positioning member 30, and the locking members 42 are located directly above the spacers 60, so that the spacers 60 and the locking members 42 are correspondingly disposed. Figure 2 and Figure 3 As shown.

[0057] When the spacer 60 and the locking member 42 are not correspondingly configured, the locking member 42 applies pressure to the pressing member 41. Because the position of the locking member 42 applying pressure does not correspond to the spacer 60, the force on the first positioning member 20 and the second positioning member 30 is uneven, causing deformation of either the first positioning member 20 or the second positioning member 30. In this embodiment, by correspondingly configuring the spacer 60 and the locking member 42, when the locking member 42 applies pressure to the pressing member 41, the pressure is transmitted through the spacer 60, ensuring balanced force on the first positioning member 20 and the second positioning member 30, preventing deformation of either the first positioning member 20 or the second positioning member 30, and improving the consistency of the gap size of the inspection groove 50.

[0058] According to some embodiments of this application, a groove 411 is provided on the side of the clamping member 41 away from the locking member 42, and a portion of the first positioning member 20 or the second positioning member 30 is disposed in the groove 411 so that the clamping member 41 abuts against the first positioning member 20 or the second positioning member 30.

[0059] In this embodiment, the groove 411 is provided along the length direction of the clamping member 41. In other embodiments, the groove 411 is provided along the width direction of the clamping member 41.

[0060] The cross-sectional shape of the groove 411 includes, but is not limited to, an arc shape, a polygon shape, or an irregular shape. In this embodiment, the groove 411 matches the shape of a portion of the first positioning member 20 or a portion of the second positioning member 30. For example, the cross-sectional shape of the groove 411 is semi-circular, and a portion of the first positioning member 20 or a portion of the second positioning member 30 is located within the groove 411, thereby increasing the contact area between the first positioning member 20 or the second positioning member 30 and the clamping member 41.

[0061] In some embodiments, the clamping member 41 has a groove 411 on the side away from the locking member 42, and a portion of the first positioning member 20 is located in the groove 411, that is, the outer surface of a portion of the first positioning member 20 contacts the groove 411 so that the clamping member 41 abuts against the first positioning member 20.

[0062] In some embodiments, the clamping member 41 is provided with a groove 411 on the side away from the locking member 42, and a portion of the second positioning member 30 is located in the groove 411, that is, the outer surface of a portion of the second positioning member 30 contacts the groove 411 so that the clamping member 41 abuts against the second positioning member 30.

[0063] In this embodiment, by partially positioning the first positioning member 20 or partially positioning the second positioning member 30 within the groove 411, the first positioning member 20 or the second positioning member 30 abuts against the clamping member 41, thereby increasing the contact area between the first positioning member 20 or the second positioning member 30 and the clamping member 41. This improves the consistency of the gap size of the inspection groove 50, enhances the accuracy of inspecting the twisted needle, and thus improves the reliability of the inspection device 1 and reduces production costs.

[0064] According to some embodiments of this application, at least one locking hole 11 is provided on the side of the main body 10 away from the first positioning member 20 or the second positioning member 30, and the locking member 42 passes through the locking hole 11 and abuts against the pressing member 41. The locking hole 11 includes, but is not limited to, a screw hole or a through hole.

[0065] The locking hole 11 is correspondingly provided with the locking element 42. For example... Figure 3 As shown, there are two locking holes 11 and two locking parts 42.

[0066] In some embodiments, the locking hole 11 communicates with the accommodating space of the body 10 so that the locking member 42 abuts against the pressing member 41 through the locking hole 11.

[0067] In this embodiment, the locking member 42 abuts against the pressing member 41 through the locking hole 11, so that the locking member 42 applies pressure to the pressing member 41, and then the pressing member 41 applies pressure to the first positioning member 20 or the second positioning member 30, thereby enabling adjustment of the distance between the first positioning member 20 and the second positioning member 30.

[0068] According to some embodiments of this application, at least one spacer 60 is three spacers 60, at least one locking member 42 is three locking members 42, the three spacers 60 are spaced apart along the length direction of the main body 10, and each locking member 42 is located above the corresponding spacer 60.

[0069] In some embodiments, three spacers 60 are spaced apart between the first positioning member 20 and the second positioning member 30 along the length direction of the main body 10, the clamping member 41 abuts against the first positioning member 20 or the second positioning member 30, and three locking members 42 are spaced apart on the side of the clamping member 41 away from the first positioning member 20 or the second positioning member 30, and the three locking members 42 are respectively located above the corresponding spacers 60.

[0070] For example, three spacers 60 are spaced apart along the length of the main body 10 and are located at the two ends and the middle position between the first positioning member 20 and the second positioning member 30, respectively. The three locking members correspond one-to-one with the three spacers 60 and are located above the corresponding spacers 60.

[0071] This embodiment uses three spacers 60 and three locking elements 42. The spacers 60 are spaced apart to make the pressure distribution more uniform, thereby improving the consistency of the gap size of the inspection groove 50, improving the accuracy of inspecting the twisted needle, thus improving the reliability of the inspection device 1 and reducing production costs.

[0072] According to some embodiments of this application, such as Figure 2 and Figure 3 As shown, in this embodiment, the first positioning member 20 includes a first roller, and the second positioning member 30 includes a second roller; the first roller abuts against the pressing assembly 40, and the second roller is located between the first roller and the inner wall of the main body 10; or, the second roller abuts against the pressing assembly 40, and the first roller is located between the second roller and the inner wall of the main body 10.

[0073] The materials of the first and second rollers include, but are not limited to, alloys, which can improve the strength of the first and second rollers and make them less prone to deformation under pressure.

[0074] In some embodiments, the first roller and the second roller are disposed within the accommodating space of the main body 10, and the spacer 60 is disposed between the first roller and the second roller; the pressing assembly 40 is disposed within the accommodating space and abuts against the first roller; at this time, the second roller is located between the first roller and the inner sidewall of the main body 10; the pressing assembly 40 applies pressure to the first roller to adjust the distance between the first roller and the second roller so that the gap size of the inspection groove 50 between the first roller and the second roller is consistent.

[0075] In some embodiments, the first roller and the second roller are disposed within the accommodating space of the main body 10, and the spacer 60 is disposed between the first roller and the second roller; the pressing assembly 40 is disposed within the accommodating space and abuts against the second roller; at this time, the first roller is located between the second roller and the inner sidewall of the main body 10; the pressing assembly 40 applies pressure to the second roller to adjust the distance between the first roller and the second roller so that the gap size of the inspection groove 50 between the first roller and the second roller is consistent.

[0076] In this embodiment, the first roller or the second roller abuts against the pressing assembly 40. The pressing assembly 40 applies pressure to the first roller or the second roller to adjust the distance between the first roller and the second roller, so that the gap size of the inspection groove 50 between the first roller and the second roller is consistent, which improves the accuracy of inspecting twisted needles, thereby improving the reliability of the inspection device 1 and reducing production costs.

[0077] According to some embodiments of this application, such as Figure 3 As shown, the main body 10 of this embodiment is provided with a material discharge trough 12, which is correspondingly provided with the inspection trough 50.

[0078] The material discharge trough 12 includes, but is not limited to, an opening or a through groove. For example, in this embodiment, the material discharge trough 12 is an opening, and the material discharge trough 12 is connected to the accommodating space of the main body 10, so that the material discharge trough 12 is correspondingly set with the inspection groove 50, so that the twisted needles can enter the inspection groove 50 through the material discharge trough 12 for screening.

[0079] In some embodiments, the width of the discharge trough 12 is greater than the width of the inspection trough 50. When the twisted needles enter the inspection trough 50 through the discharge trough 12 for screening, the discharge trough 12 can be used as a buffer area to reduce the possible accumulation or damage when the twisted needles fall directly into the inspection trough 50.

[0080] In this embodiment, a material discharge groove 12 is provided on the side wall of the main body 10. The material discharge groove 12 is correspondingly provided with the inspection groove 50. The material discharge groove 12 facilitates the guidance of twisted needles into the inspection groove 50, thereby improving the screening efficiency of twisted needles.

[0081] According to some embodiments of this application, such as Figure 3 As shown, the side wall of the main body 10 in this embodiment is provided with an opening 13, which communicates with the accommodating space. The first positioning member 20, the second positioning member 30 and the pressing assembly 40 are disposed in the accommodating space through the opening 13.

[0082] For example, the two opposite sidewalls of the main body 10 are respectively provided with openings 13, and both openings 13 are connected to the accommodating space. The first positioning member 20, the second positioning member 30 and the pressing assembly 40 enter the accommodating space through one opening 13. The two spacers 60 are respectively disposed between the first positioning member 20 and the second positioning member 30 through the corresponding openings 13 of the main body 10, so that an inspection groove 50 is formed between the first positioning member 20 and the second positioning member 30.

[0083] In this embodiment, an opening 13 is provided on the side wall of the main body 10, which makes the installation of the first positioning member 20, the second positioning member 30, the clamping assembly 40 and the spacer 60 easier.

[0084] In summary, this application applies pressure to the first positioning member 20 or the second positioning member 30 by pressing the clamping component 40, thereby adjusting the distance between the first positioning member 20 and the second positioning member 30. In other words, the clamping component 40 can adjust the distance between the first positioning member 20 and the second positioning member 30, thus adjusting the gap size of the inspection groove 50. This enables the inspection of twisted needles with different outer diameters. The clamping component 40 abuts against the first positioning member 20 or the second positioning member 30, increasing the contact area between them, thereby improving the consistency of the gap size of the inspection groove 50, increasing the accuracy of twisted needle inspection, improving the reliability of the inspection device 1, and reducing production costs.

[0085] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
