[0002] As a key part of a connector, the dimensional accuracy of the twist pin is crucial to the performance of the final product. During the production process, ensuring that the outer diameter of the twist pin is qualified is a key step to ensure product quality. However, due to the small size of the twist pin, the traditional manual measurement and screening method is not only inefficient, but also difficult to ensure the accuracy of the measurement.

The inspection fixture 100 mainly adopts a three-point locking method to adjust the gap of the detection slot 130 to detect the outer diameter of the twist needle. Although this three-point locking method can provide uniform pressure and a good locking effect, when used for the outer diameter size screening of the twist needle, the consistency of the gap size of the detection slot 130 of the three-point locking method is low, resulting in a decrease in the accuracy of the outer diameter of the twist needle, thereby reducing the reliability of the inspection fixture 100 and increasing the production cost.

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

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

[0035] This application provides a twist needle inspection device, see Figure 2-Figure 3 As shown, Figure 2 It is a structural schematic diagram of an embodiment of the inspection device provided by the present application; Figure 3 yes Figure 2 The inspection device 1 of this embodiment comprises a main body 10, a first positioning member 20, a second positioning member 30 and a pressing assembly 40; the inspection device 1 of this embodiment is used to detect the outer diameter of the twist needles so as to screen the twist needles.

[0036] The main body 10 has a receiving space, and the first positioning member 20 and the second positioning member 30 are disposed in the receiving space. For example, the main body 10 is hollowed to form the receiving space, 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 member 20 and the second positioning member 30 are spaced apart to form a test groove 50, that is, the gap between the first positioning member 20 and the second positioning member 30 forms the test groove 50; the test groove 50 is used to screen the twist needles to detect the outer diameter of the twist needles. For example, if the outer diameter of the twist needle is less than or equal to the gap size of the test groove 50, the corresponding twist needle passes through the test groove 50.

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

[0039] The clamping assembly 40 is disposed in 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 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 firstly arranged in the accommodating space at intervals, and then the pressing assembly 40 is arranged in the accommodating space, and the pressing assembly 40 abuts against the first positioning member 20. Figure 2 At this time, the clamping assembly 40 applies pressure to the first positioning member 20 to adjust the spacing 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 spaced apart in the accommodating space, and then the clamping assembly 40 is disposed in the accommodating space, and the clamping assembly 40 abuts against the second positioning member 30; at this time, the clamping assembly 40 applies pressure to the second positioning member 30 to adjust the distance between the second positioning member 30 and the first positioning member 20 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 pressure is applied to the first positioning member 20 or the second positioning member 30 by the clamping assembly 40, so that the distance between the first positioning member 20 and the second positioning member 30 can be adjusted, that is, the distance between the first positioning member 20 and the second positioning member 30 can be adjusted by the clamping assembly 40, that is, the gap size of the inspection groove 50 can be adjusted by the clamping assembly 40, so that the inspection of twist needles with different outer diameters can be realized; the clamping assembly 40 abuts against the first positioning member 20 or the second positioning member 30, which can increase the contact area between the clamping assembly 40 and the first positioning member 20 or the second positioning member 30, thereby improving the consistency of the gap size of the inspection groove 50, improving the accuracy of inspecting twist needles, thereby improving the reliability of the inspection device 1 and reducing the production cost.

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

[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, the first positioning member 20, the second positioning member 30 and the spacer 60 are disposed in the accommodation space, and the spacer 60 is located between the first positioning member 20 and the second positioning member 30, and the clamping assembly 40 is disposed in the accommodation space and abuts against the first positioning member 20 or the second positioning member 30. The clamping 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, and the spacing between the first positioning member 20 and the second positioning member 30 can be adjusted through the spacer 60.

[0046] The thickness of the spacer 60 can determine the distance between the first positioning member 20 and the second positioning member 30, that is, the thickness of the spacer 60 is equal to the gap size of the inspection slot 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 twist needles with different outer diameters can be screened through the inspection slot 50.

[0047] In some embodiments, the material of the spacer 60 is a rigid material, including but not limited to steel, aluminum alloy or titanium alloy. Since non-rigid materials are easily deformed by external forces, the stability of the inspection slot 50 is reduced, and unpredictable deformations are easily caused during the inspection process, thereby increasing the inspection error and reducing the reliability of the inspection results. The material of the spacer 60 of this embodiment is a rigid material, which is not easy to deform, can provide higher structural rigidity, and enhance the stability and anti-deformation ability of the inspection slot 50.

[0048] In this embodiment, by disposing at least one spacer 60 between the first positioning member 20 and the second positioning member 30, the structural stability between the first positioning member 20 and the second positioning member 30 can be enhanced, that is, the stability of the inspection slot 50 can be enhanced, and the consistency of the gap size of the inspection slot 50 during long-term use can be improved.

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

[0050] The pressing 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 pressing member 41 .

[0051] In some embodiments, the pressing member 41 abuts against the first positioning member 20 , and the locking member 42 applies pressure to the pressing member 41 , so that the pressing 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 pressing member 41 abuts against the second positioning member 30 , and the locking member 42 applies pressure to the pressing member 41 , so that the pressing 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 cooperates with the pressing member 41 , and the locking member 42 applies pressure to the pressing member 41 , thereby enabling the pressing member 41 to apply 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 .

[0054] According to some embodiments of the present application, the spacer 60 is disposed corresponding to the locking member 42 .

[0055] In some embodiments, the inspection device 1 includes a spacer 60, which is arranged between the first positioning member 20 and the second positioning member 30, and the clamping assembly 40 includes a locking member 42; at this time, the locking member 42 is arranged 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 arranged correspondingly.

[0056] In some embodiments, the inspection device 1 includes two spacers 60, and the two spacers 60 are respectively arranged at the two end positions between the first positioning member 20 and the second positioning member 30, and the clamping assembly 40 includes two locking members 42; at this time, the two locking members 42 are respectively arranged at the two end positions of 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 arranged correspondingly, such as Figure 2 and Figure 3 shown.

[0057] In the case where the spacer 60 and the locking member 42 are not arranged in correspondence, the locking member 42 applies pressure to the pressing member 41. Since the position where the locking member 42 applies pressure is not arranged in correspondence with the spacer 60, the force between the first positioning member 20 and the second positioning member 30 is unbalanced, resulting in deformation of the first positioning member 20 or the second positioning member 30. In this embodiment, the spacer 60 and the locking member 42 are arranged in correspondence. When the locking member 42 applies pressure to the pressing member 41, the pressure is transmitted through the spacer 60, so that the first positioning member 20 and the second positioning member 30 are balanced in force, deformation of the first positioning member 20 or the second positioning member 30 is avoided, and the consistency of the gap size of the inspection slot 50 is improved.

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

[0059] The groove 411 is disposed along the length direction of the pressing member 41. In other embodiments, the groove 411 is disposed along the width direction of the pressing member 41.

[0060] The cross-sectional shape of the groove 411 includes, but is not limited to, an arc shape, a polygonal shape, or an irregular shape. The groove 411 of this embodiment 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 a semicircle, and a portion of the first positioning member 20 or a portion of the second positioning member 30 is located in the groove 411, thereby increasing the contact area between the first positioning member 20 or the second positioning member 30 and the pressing member 41.

[0061] In some embodiments, a groove 411 is provided on the side of the clamping member 41 away from the locking member 42, and part of the first positioning member 20 is located in the groove 411, that is, part of the outer surface 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, a groove 411 is provided on the side of the clamping member 41 away from the locking member 42, and part of the second positioning member 30 is located in the groove 411, that is, part of the outer surface 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, part of the first positioning member 20 or part of the second positioning member 30 is arranged in the groove 411, so that the first positioning member 20 or the second positioning member 30 is abutted with 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, thereby improving the consistency of the gap size of the inspection groove 50, improving the accuracy of inspecting the twist needle, thereby improving the reliability of the inspection device 1 and reducing the production cost.

[0065] The locking hole 11 is arranged correspondingly to the locking member 42. Figure 3 As shown, the number of locking holes 11 is 2, and the number of locking members 42 is 2.

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

[0067] The locking member 42 of this embodiment 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 adjusting the distance between the first positioning member 20 and the second positioning member 30.

[0070] For example, three spacers 60 are arranged at intervals along the length direction of the main body 10 and are respectively located at the two end positions and the middle position between the first positioning member 20 and the second positioning member 30. The three locking members correspond one by one to the three spacers 60 and are respectively located above the corresponding spacers 60.

[0071] In this embodiment, three spacers 60 and three locking members 42 are provided. The three spacers 60 are provided at intervals, so that the pressure distribution is more uniform, thereby improving the consistency of the gap size of the inspection groove 50, improving the accuracy of inspecting the twist needle, thereby improving the reliability of the inspection device 1 and reducing the production cost.
