[0002] In the process of manufacturing threaded holes, a gauge body is usually used to ensure the quality and accuracy of the threaded holes. In the current prior art, gauge bodies of different specifications are usually customized according to different threaded hole depths to ensure the accuracy and quality of the threaded hole machining. However, this customized manufacturing method has some disadvantages: First, the cost is high: Customizing gauge bodies of different specifications requires additional cost investment, including design, manufacturing, and maintenance costs, increasing the production cost; Second, the production cycle is long: Customizing gauge bodies requires a long manufacturing and debugging cycle, resulting in an extended production cycle, affecting production capacity and delivery time; Third, there is a waste of human resources: Managing and using gauge bodies of different specifications requires additional human resource investment, increasing labor costs and management difficulties; Fourth, it is not universal: The customized gauge bodies are usually only applicable to the machining of threaded holes with specific depths and cannot flexibly adapt to the requirements of threaded holes with different depths, reducing the flexibility and efficiency of production.

[0003] Therefore, there is a lack of a thread plug gauge assembly in the prior art that can flexibly measure threaded holes with different depths. Summary of the Utility Model

[0004] One technical problem to be solved by the utility model is that the existing thread plug gauges cannot flexibly measure threaded holes with different depths.

[0005] To solve the above technical problem, an embodiment of the utility model provides a thread plug gauge assembly, including a holding part and a go end for detecting threads. The thread plug gauge assembly further includes:

[0006] A transition part, both ends of the transition part are fixedly connected to the go end and the holding part respectively, and the transition part is provided with a first mating part; and

[0007] A sliding member, on which a second mating part is arranged, and the sliding member can slide axially relative to the transition part to cover a part of the go end;

[0008] Wherein, the first mating part and the second mating part cooperate with each other to make the sliding member and the transition part relatively fixed.

[0009] In some embodiments, the first mating part is a recessed part, and an upper limit and a lower limit are arranged on the recessed part, and the upper limit and the lower limit are respectively used to control the upper and lower limits of the sliding of the second mating part relative to the first mating part.

[0010] In some embodiments, the thread plug gauge assembly further includes a fastener, the sliding member has a through hole, and the fastener is used to pass through the through hole to fix the sliding member on the transition part.

[0011] In some embodiments, the fastener is a screw, the through-hole is a threaded hole, and the screw passes through the threaded hole to fix the sliding member on the first mating portion.

[0012] In some embodiments, the sliding member is a sleeve, and the sleeve is sleeved on the transition portion.

[0013] In some embodiments, the sleeve is columnar, and the axis of the sleeve is on the same straight line as the axis of the transition portion.

[0014] In some embodiments, the thread plug gauge assembly includes at least two sliding members with different depths so that the sliding members can cover different lengths of the partial go end.

[0015] In some embodiments, the maximum outer diameter of the transition portion is greater than the maximum outer diameter of the go end, and the inner diameter of the sliding member is greater than the outer diameter of the go end.

[0016] In some embodiments, the first mating portion is a groove, and the groove is semi-cylindrical.

[0017] In some embodiments, the thread plug gauge assembly further includes an anti-slip gasket, and the anti-slip gasket is disposed between the head of the screw and the through-hole.

[0033] Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the description.

[0034] An embodiment of the present utility model provides a thread plug gauge assembly 1, as Figures 1-5 shown, including a holding portion 2 and a go end 3. The go end 3 is used to detect threads. The thread plug gauge assembly 1 further includes a transition portion 4 and a sliding member 5. Two ends of the transition portion 4 are respectively fixedly connected to the go end 3 and the holding portion 2. The transition portion 4 is provided with a first engaging portion 41; a second engaging portion 51 is provided on the sliding member 5, and the sliding member 5 can slide axially relative to the transition portion 4 to cover a part of the go end 3;

[0035] Wherein, the first engaging portion 41 and the second engaging portion 51 cooperate with each other to make the sliding member 5 and the transition portion 4 relatively fixed.

[0036] Among them, if the sliding member 5 is not installed on the go end 3 of the thread plug gauge assembly 1, a thread with one depth can be detected; if the sliding member 5 is installed on the go end 3 and the sliding member 5 moves on the first mating portion 41, threads with multiple depths within a certain depth range can be detected; one plug gauge can detect multiple threads, improving the flexibility and efficiency of production. Compared with the prior art where one plug gauge can only detect a thread with one depth, the present utility model reduces the production cost; using one thread plug gauge assembly 1 can also reduce the complexity of manual operation and improve the automation level of the production line; due to the same threads, it is more convenient for assembly and maintenance.

[0037] In some embodiments, as Figure 5 shown, the first mating portion 41 is a recessed portion, and an upper limit 412 and a lower limit 413 are provided on the recessed portion. The upper limit 412 and the lower limit 413 are respectively used to control the upper and lower limits of the sliding of the second mating portion 51 relative to the first mating portion 41. The upper limit 412 and the lower limit 413 respectively limit the two extreme positions of the mechanical stroke of the second mating portion 51 relative to the first mating portion 41, so that the depth of the thread that the thread plug gauge assembly 1 can detect is fixed within a range, enabling the plug gauge to detect a thread with a standard depth and then threads with a certain depth range of up and down fluctuations, improving the production efficiency.

[0038] In some embodiments, the thread plug gauge assembly 1 further includes a fastener 6. The sliding member 5 has a through hole 52, and the fastener 6 is used to pass through the through hole 52 to fix the sliding member 5 on the transition portion 4. The provision of the fastener 6 facilitates fixing the second mating portion 51 on the first mating portion 41, and the through hole 52 also facilitates the passing of the fastener 6, improving the fixing efficiency of the sliding member 5.

[0039] In some embodiments, the fastener 6 is a screw 61, and the through hole 52 is a threaded hole 521. The screw 61 passes through the threaded hole 521 to fix the sliding member 5 on the first mating portion 41. With the cooperation of the screw 61 and the threaded hole 521, the sliding member 5 is fixed on the first mating portion 41 after the screw 61 is tightened, and the threaded hole 521 can be measured; if the tightened screw 61 is loosened, the sliding member 5 can be moved on the first mating portion 41 to measure threaded holes 521 with other depths.

[0040] In some embodiments, the sliding member 5 is a sleeve 53. The sleeve 53 is sleeved on the transition portion 4. The sleeve 53 and the transition portion 4 are in transitional fit, which facilitates the movement of the sleeve 53 along the axis on the transition portion 4. Compared with interference fit, transitional fit can reduce the stress on the parts during assembly, thereby reducing the risk of deformation and damage, enabling the sleeve 53 to be used on a set of gauge bodies with the same internal thread diameter but different dimensional lengths. At the same time, parts with transitional fit are usually easier to assemble and disassemble, which can reduce the mutual wear between components and lower the usage cost.

[0041] In some embodiments, the sleeve 53 is columnar, and the axis of the sleeve 53 is collinear with the axis of the transition portion 4, which facilitates the movement of the sleeve 53 on the transition portion 4. At the same time, it also ensures the accuracy of the movement of the sleeve 53, preventing the end face of the sleeve 53 from deflecting, thereby improving the detection accuracy of the thread.

[0042] In some embodiments, as Figure 1 、 Figure 2 shown, the plug gauge thread assembly includes at least two sliding members 5 with different depths so that the sliding members 5 can cover different lengths of the partial through - end 3. As Figure 1 shown, by setting three sliding members 5 with different lengths, at least three lengths of the partial through - end 3 can be covered. Each length of the sliding member 5 can detect the thread within a certain depth range. Compared with the detection efficiency of a conventional plug gauge that can only detect threads of one depth, the thread plug gauge assembly 1 in this embodiment can flexibly adapt to the requirements of thread holes 521 with different depths, improving the flexibility and efficiency of production.

[0043] In some embodiments, as Figure 3 、 Figure 4 shown, the maximum outer diameter of the transition portion 4 is greater than the maximum outer diameter of the through - end 3, and the inner diameter of the sliding member 5 is greater than the outer diameter of the through - end 3, which facilitates the axial movement of the sliding member 5 on the transition portion 4, preventing the sliding member 5 from colliding with the thread of the through - end 3 during movement and causing wear, and improving the service life of the thread plug gauge assembly 1.

[0044] In some embodiments, the first mating portion 41 is a groove 411. The groove 411 is semi - cylindrical. The semi - cylindrical groove 411 can provide a certain self - positioning ability, enabling the mating sliding member 5 to be more easily aligned and positioned. At the same time, the semi - cylindrical groove 411 can reduce the error during the assembly process, improve the accuracy of assembly, and the semi - cylindrical groove 411 can also distribute the contact stress more evenly and provide better mating strength.

[0045] In some embodiments, the thread plug gauge assembly 1 further includes an anti-slip gasket disposed between the head of the screw 61 and the through hole 52. The anti-slip gasket can increase the friction between the screw 61 and the through hole 52, prevent the screw 61 from loosening under vibration or impact, and thus improve the stability of the overall structure. Disposing the anti-slip gasket between the head of the screw 61 and the through hole 52 can reduce the wear caused by direct contact and extend the service life of the screw 61 and the through hole 52.

[0046] So far, the embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions of the present invention based on the above description.

[0047] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
