Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of connector aperture measuring tools, and in particular to a rapid connector aperture detection tool. Background Technology
[0002] Connectors are widely used in communications and power transmission, and come in a wide variety of types and shapes. However, during the manufacturing process, it is necessary to inspect certain hole diameters and adjust the processing parameters accordingly to ensure the accuracy of the hole diameters. For example, positioning holes used to ensure precise alignment of plugs and sockets may lead to mis-insertion or mechanical interference if the tolerance is too large. Similarly, guide holes used to guide connector alignment during mating may cause increased friction if the hole diameter is off.
[0003] However, existing measuring tools have the following shortcomings: 1. For example, go / no-go gauges, although they can quickly determine whether the hole diameter is within the appropriate tolerance range, require frequent replacement of go / no-go gauges when measuring holes of various diameters, such as positioning holes and guide holes of connectors, to adapt to specific dimensional tolerances, which affects the overall inspection efficiency; 2. For example, vernier calipers, although they can also quickly measure the hole diameter, require high skill from the inspectors. Different force applied during the inspection process will yield different inspection results, which is not conducive to measuring the high-precision hole diameters such as positioning holes and guide holes of connectors.
[0004] To address this, we designed a rapid connector aperture detection tool. Utility Model Content
[0005] To overcome the shortcomings of the prior art, this utility model discloses a rapid connector aperture detection tool.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A rapid connector aperture inspection tool, comprising:
[0008] straight handle;
[0009] A large-diameter conical ruler is coaxially mounted at one end of the straight handle;
[0010] A small-diameter conical ruler is coaxially mounted on the other end of the straight handle;
[0011] Both the large-diameter tapered ruler and the small-diameter tapered ruler include:
[0012] The main scale of the truncated cone has a straight handle connected to its major diameter end;
[0013] A vernier scale includes a positioning part that is axially slidably connected to the main scale, a vernier part that slides along the generatrix of the main scale and is radially slidably connected to the positioning part, and a locking member that locks the position of the vernier part.
[0014] Furthermore, the main scale of the large-aperture conical cylindrical ruler is hollow inside, and first sliding grooves are provided on both symmetrical sides;
[0015] The positioning part of the large-aperture tapered cylindrical ruler radially penetrates the first sliding groove, and a first sliding track is provided on the side corresponding to the straight handle.
[0016] The vernier section of the large-aperture tapered ruler is slidably connected to the first groove and the first slide.
[0017] Furthermore, the inner cavity of the main scale of the truncated cone is provided with a guide post and an inclined post located between the guide post and the first sliding groove;
[0018] The locking component of the large-diameter tapered scale is a locking screw, which locks the vernier section by contacting the inclined column.
[0019] Furthermore, the top and bottom of the inclined column are connected to form an isosceles trapezoidal structure;
[0020] The end of the guide post away from the straight handle is provided with a necked thread section, which is screwed to the main scale of the truncated cone and pressed into the isosceles trapezoidal structure.
[0021] Furthermore, a large end plate is provided at one end of the straight handle corresponding to the large-diameter conical scale; a mating hole is provided in the middle of the large end plate to engage with the guide post; the large end plate is connected to the isosceles trapezoidal structure and the large-diameter end of the truncated cone scale by bolts.
[0022] Furthermore, the main scale of the small-aperture conical ruler has a cylindrical cavity inside and second sliding grooves on both symmetrical sides;
[0023] The positioning part of the small-aperture conical ruler is provided with a cylindrical sliding part that is slidably connected to a cylindrical cavity, and a second slide is provided.
[0024] The vernier section of the small-aperture tapered ruler is slidably connected to the second slide groove and the second slide rail.
[0025] Furthermore, the locking component of the small-diameter tapered ruler includes a stud that penetrates the cylindrical sliding part and a clamping nut; the clamping nut is threadedly connected to the stud and abuts against the vernier part to achieve locking.
[0026] Furthermore, a small end plate is provided at one end of the straight handle corresponding to the small-diameter conical scale; the small end plate is connected to the large-diameter end of the small conical scale by bolts.
[0027] Furthermore, both the large-aperture conical scale and the small-aperture conical scale have two vernier sections, symmetrically distributed on both sides of the corresponding truncated cone main scale.
[0028] Furthermore, the surface of the straight handle is provided with anti-slip texture; the end of the truncated cone main scale away from the straight handle has a dome structure.
[0029] Compared with the prior art, the beneficial effects of this utility model are:
[0030] 1. By setting a large-diameter tapered ruler and a small-diameter tapered ruler at both ends of the straight handle, it can cover the inspection needs of connectors with different hole diameters (such as positioning holes, guide holes, fixing holes, etc.). Compared with traditional go / no-go gauges that require frequent tool changes, this tool can complete the measurement of multiple hole diameters with a single device, significantly reducing tool changeover time and improving inspection efficiency;
[0031] 2. The design of axial adjustment of the positioning part and multi-dimensional adjustment of the generatrix direction and radial direction of the vernier part allows the positioning part to be fixed in position during measurement. The insertion force is based solely on the gravity of the truncated cone main scale and the straight handle. No additional pressure is required from the operator. This design avoids measurement deviations caused by uneven operating force. It is especially suitable for the detection of positioning holes and guide holes with high precision requirements, and effectively improves the stability and consistency of measurement results.

[0040] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.
[0041] Example 1, in conjunction with Appendix Figure 1-3 A connector aperture rapid detection tool includes a straight handle 1. One end of the straight handle 1 is provided with a large-diameter tapered ruler 2 coaxial with it, which is used to detect larger-diameter holes in the connector, such as fixing holes and sealing holes of the connector. The other end is provided with a small-diameter tapered ruler 3 coaxial with it, which is used to detect smaller-diameter holes in the connector, such as positioning holes and guide holes.
[0042] The tapered scale includes a truncated cone main scale and a vernier scale; the major diameter end of the truncated cone main scale is connected to the straight handle 1. The vernier scale includes a positioning part and a vernier part. The positioning part is slidably connected to the truncated cone main scale along its axial direction, and the vernier part is slidably connected to the truncated cone main scale along its generatrix direction.

Due to the characteristics of the truncated cone main scale shape, this measuring tool can adapt to a certain range of hole diameter measurements, increasing the measurement range compared to go / no-go gauges and solving the technical problem of frequent tool changes during measurement.
