[0002] In engineering applications, the stud structure of some application occasions cannot adopt tool withdrawal groove processing mode to avoid stress concentration points, and can only adopt tool withdrawal groove-free processing mode, so the thread obtained by this processing mode includes effective thread part and ineffective thread part.

[0023] Figure 1 The structure of the stud structure interface measuring device in an embodiment of the present application is shown. For ease of illustration, the drawings only show the structures related to the embodiments of the present application.
[0024] Please refer to Figure 1The stud structure interface measuring device 100 in the preferred embodiment of the utility model includes a main body structure 110. The main body structure 110 has opposite upper limit value measuring ends 111 and lower limit value measuring ends 112. The end face of the upper limit value measuring end 111 is formed with an upper limit value detection threaded hole 120 made according to a gauge. The end face of the lower limit value measuring end 112 is formed with a lower limit value detection threaded hole 130 made according to a gauge. The depth of the upper limit value detection threaded hole 120 is greater than the depth of the lower limit value detection threaded hole 130. The side face of the main body structure 110 is formed with an observation gap 140. The bottom face of the upper limit value detection threaded hole 120 and the bottom face of the lower limit value detection threaded hole 130 are both planes, and both are exposed in the observation gap 140. Specifically, a plane perpendicular to the depth direction of the observation gap 140 is defined as a projection face, and the orthographic projection of the bottom face of the upper limit value detection threaded hole 120 and the bottom face of the lower limit value detection threaded hole 130 on the projection face are both located in the orthographic projection of the observation gap 140 on the projection face, so that the staff member does not need to find an observation angle, and can clearly see the bottom face of the upper limit value detection threaded hole 120 and the bottom face of the lower limit value detection threaded hole 130 above and on the side of the observation gap 140.
[0025] The depth of the upper limit value detection threaded hole 120 and the depth of the lower limit value detection threaded hole 130 are respectively consistent with the maximum limit value and the minimum limit value of the effective thread length in the stud structure 200 to be detected. Since the bottom face of the upper limit value detection threaded hole 120 and the bottom face of the lower limit value detection threaded hole 130 are both exposed in the observation gap 140, the staff member can view the situation of the bottom face of the upper limit value detection threaded hole 120 and the bottom face of the lower limit value detection threaded hole 130 through the observation gap 140.
[0026] Since the stud in the stud structure 200 to be detected cannot be processed by a tool withdrawal groove, the thread depth of the non-effective thread part will be shallower in the thread processing process of the stud, and the upper limit value detection threaded hole 120 and the lower limit value detection threaded hole 130 are both made according to a gauge, so only the effective thread part of the stud structure 200 to be detected can be screwed into the upper limit value detection threaded hole 120 and the lower limit value detection threaded hole 130. Therefore, when the stud end of the stud structure 200 to be detected is screwed into the upper limit value detection threaded hole 120 or the lower limit value detection threaded hole 130 and tightened, the non-effective thread part of the stud structure 200 to be detected can only be outside the main body structure 110, at which time the staff member can determine whether the effective thread length is qualified by determining whether the stud front end face of the stud structure 200 to be detected is in complete contact with the bottom face of the upper limit value detection threaded hole 120 and the bottom face of the lower limit value detection threaded hole 130 respectively, and by determining the number of thread teeth exposed outside the main body structure 110.
[0027] Therefore, the stud structure interface measuring device 100 combines the effective thread length inspection and the go gauge inspection, and completes the effective thread length inspection of the stud structure while performing the go gauge inspection on the stud of the stud structure, without the need for multiple point selection measurement, thereby reducing the inspection procedures and workload. Moreover, in the effective thread length detection process, the non-effective thread part cannot be screwed into the lower limit value detection thread hole 130 and the upper limit value detection thread hole 120, so whether the effective thread length is qualified is determined by the number of thread teeth exposed outside the main body structure 110 after tightening, thereby effectively ensuring the accuracy of the detection. Therefore, the use of the stud structure interface measuring device 100 effectively improves the effective thread length detection accuracy and detection efficiency of the stud structure.
[0028] In some embodiments, the upper limit value detection thread hole 120 and the lower limit value detection thread hole 130 are coaxially arranged. Coaxial arrangement of the upper limit value detection thread hole 120 and the lower limit value detection thread hole 130 not only reduces the volume of the main body structure 110 and improves the convenience of use of the stud structure interface measuring device 100, but also enables the bottom surface of the upper limit value detection thread hole 120 and the bottom surface of the lower limit value detection thread hole 130 to be clearly seen even if the observation gap 140 formed on the main body structure 110 is small.
[0029] In some embodiments, the bottom of the upper limit value detection thread hole 120 is circumferentially provided with a first groove 150. The bottom surface of the upper limit value detection thread hole 120 serves as part of the inner wall of the first groove 150. The bottom of the lower limit value detection thread hole 130 is circumferentially provided with a second groove 160. The bottom surface of the lower limit value detection thread hole 130 serves as part of the inner wall of the second groove 160. The first groove 150 and the second groove 160 are actually the tool withdrawal grooves of the upper limit value detection thread hole 120 and the lower limit value detection thread hole 130, respectively. Therefore, the provision of the first groove 150 and the second groove 160 not only makes the machining of the upper limit value detection thread hole 120 and the lower limit value detection thread hole 130 more convenient, but also enlarges the bottom surface of the upper limit value detection thread hole 120 and the bottom surface of the lower limit value detection thread hole 130, thereby enabling the worker to more easily and accurately determine whether the front end surface of the stud of the stud structure 200 to be detected is in complete contact with the bottom surface of the upper limit value detection thread hole 120 or the bottom surface of the lower limit value detection thread hole 130 after tightening during the effective thread length inspection of the stud structure, thereby improving the convenience of the effective thread length inspection of the stud structure.
[0030] In one embodiment of this utility model, the main structure 110 is a columnar structure. Along the longitudinal direction of the main structure 110, the length of the observation notch 140 is less than the length of the main structure 110. Thus, the observation notch 140 is a groove formed in the middle of the main structure 110, located between the end face of the upper limit measuring end 111 and the end face of the lower limit measuring end 112. The outer walls of both the upper limit measuring end 111 and the lower limit measuring end 112 are columnar, facilitating the placement of the stud structure 200 to be tested by the operator.
[0031] In another embodiment of this utility model, the observation notch 140 penetrates both the upper limit measuring end 111 and the lower limit measuring end 112. Thus, during the processing of the observation notch 140, only a portion of the side surface of the main structure 110 needs to be completely removed, making processing convenient and simplifying the manufacturing process of the stud structure interface measuring device 100.
[0032] In some embodiments, the main structure 110 is a cylindrical structure. An anti-slip portion 170 is formed on the outer surface of the main structure 110. This anti-slip portion 170 can be a raised ridge, raised dot, groove, or texture formed on the outer surface of the main structure 110, or it can be an anti-slip layer such as an elastic rubber layer applied to the outer surface of the main structure 110, or a protective structure such as a rubber sleeve fitted onto the outer surface of the main structure 110. The anti-slip portion 170 facilitates the operator in screwing the stud end of the stud structure 200 to be tested into the upper limit detection threaded hole 120 and the lower limit detection threaded hole 130, preventing slippage during screwing and thus avoiding accidental hand contact or the stud structure interface measuring device 100 falling off, thereby improving the safety of using the stud structure interface measuring device 100.
[0033] Specifically, the anti-slip part 170 is an anti-slip texture formed on the surface of the main structure 110. More specifically, the protective part is an anti-slip mesh. Setting the anti-slip part 170 as an anti-slip texture not only improves the firmness of the protective part on the main structure 110, reduces the probability of the protective part falling off the main structure 110 or wearing off, and extends its service life, but also makes the processing of the anti-slip part 170 simpler.
[0034] In some embodiments, a weight-reduction hole 190 communicating with the lower limit detection threaded hole 130 is provided on the bottom surface of the upper limit detection threaded hole 120. The diameter of the weight-reduction hole 190 is smaller than the bottom diameters of both the upper limit detection threaded hole 120 and the lower limit detection threaded hole 130. The weight-reduction hole 190 is mainly used to reduce the weight of the main structure 110, thereby making the stud structure interface measuring device 100 lighter and improving its ease of use.
[0035] In some embodiments, the upper limit value measuring end 111 and the lower limit value measuring end 112 are both provided with a chamfer 180 in the circumferential direction to remove the sharp corners of the upper limit value measuring end 111 and the lower limit value measuring end 112, reduce the probability of the sharp corners of the upper limit value measuring end 111 and the lower limit value measuring end 112 scratching the workers during use, and improve the use safety of the stud structure interface measuring device 100.
[0036] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
[0037] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
