Description

Technical Field

[0001] The utility model relates to the technical field of aperture detection go / no-go gauges, in particular to an assembled aperture detection go / no-go gauge. Background Art

[0002] The inner hole go and no-go gauge is a commonly used tool for inner hole diameter detection. The inner hole go and no-go gauge includes a connecting rod and a go gauge end and a no-go gauge end set at both ends of the connecting rod. During the inner hole detection, if the go gauge end can be inserted into the inner hole, and the no-go gauge end cannot be inserted into the inner hole, it means that the inner hole diameter is within the tolerance range and the inner hole is qualified. In other cases, it means that the inner hole diameter detected is unqualified.

[0003] The current internal hole go / no-go gauges are round at both ends, so they are easy to roll when placed on a processing table or a testing table, and often roll to the ground, resulting in loss or difficulty in finding. There is currently no good solution to this problem;

[0004] In addition, the existing inner hole go / no-go gauges are distributed at both ends, so in order to facilitate holding the inner hole go / no-go gauges, the length of the inner hole go / no-go gauges needs to be designed to be longer, which obviously wastes steel and increases production costs. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in order to overcome the above problems, an assembled aperture detection go / no-go gauge is provided, which solves the above problems.

[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0007] An assembled aperture detection go / no-go gauge comprises a steel through-end shaft and a stop-end shaft sleeve, wherein the outer wall of the through-end shaft is provided with a plurality of engaging grooves at annular intervals, and the inner wall of the stop-end shaft sleeve is provided with a slide plate at annular intervals, the stop-end shaft sleeve is slidably sleeved on the outside of the through-end shaft, and the slide plate is slidably arranged in the engaging grooves;

[0008] When only the through-end shaft can be inserted into the hole and the stop-end sleeve cannot be inserted into the hole after being superimposed on the through-end shaft, the hole meets the requirements;

[0009] In addition, it also includes a front sleeve end for connecting the through-end shaft, and the tail end of the front sleeve end is fixedly provided with a hand-held handle for holding, and the tail end of the through-end shaft is provided with a threaded hole for connecting with a screw fixed to the front end of the front sleeve end, so that the combination of through-end shafts and stop-end shaft sleeves of different sizes can be replaced, and an adjusting thread section is also provided on the front sleeve end, and the adjusting thread section is used to connect the stop-end thread sleeve. When only the through-end shaft is used for lower limit detection, the stop-end thread sleeve is rotated backward so that the stop-end shaft sleeve can retreat, so that the through-end shaft is inserted into the hole for detection, and when the upper limit detection is performed, the stop-end thread sleeve is rotated forward. The front end face of the stop thread sleeve is made to abut against the rear end face of the stop end sleeve to limit the position of the stop end sleeve. At this time, the front end of the stop end sleeve is flush with the front end of the through end shaft, and the stop end sleeve is stacked on the outside of the through end shaft and inserted into the hole together for detection; and in order to improve the sliding smoothness of the stop end sleeve relative to the through end shaft, grease is filled in the fitting groove, and the slide plate has magnetism after being magnetized, so that the slide plate can slide back and forth smoothly in the fitting groove, and the magnetic property makes the stop end sleeve adsorbed on the outside of the through end shaft for easy storage without external force;

[0010] In addition, the outer side wall of the front sleeve end is also provided with a plurality of stable sliding grooves at intervals in an annular manner, which are used for the slide plate to disengage from the fitting groove and then slide into the stable sliding groove when the stop sleeve slides backward, thereby effectively improving the stability of the stop sleeve;

[0011] In addition, in order to effectively reduce the weight, the front sleeve end is made of steel, and the hand handle can be made of plastic or wood. The front end of the hand handle and the rear end of the front sleeve end are fixed by bolts. In this way, under the premise of meeting the structural strength, the weight of the equipment can be effectively reduced, the amount of steel used can be reduced, and the manufacturing cost can be reduced;

[0012] In order to facilitate the holding of the handle, the handle can be set to a regular polygonal prism structure, which can effectively increase its anti-slip performance, and its side is flat, so it will not roll down when placed on a platform, which is safer than the existing technology.

[0013] Preferably, in order to further effectively improve the anti-slip property of the hand-held handle, a rubber or silicone anti-slip sleeve is adhesively mounted on its outer end surface, and a concave-convex anti-slip texture structure can be provided on the outer surface of the anti-slip sleeve accordingly. This effectively improves the anti-slip performance and will not freeze your hands during testing in winter, and the cross-sectional size of the hand-held handle can be designed to be larger than the outer diameter of the stop shaft sleeve. In this way, after the device is placed on the platform, the outer side wall of the stop shaft sleeve will not contact the platform surface, thereby preventing friction and scratches.

[0014] The advantages and positive effects of the utility model are:

[0015] 1. By providing a hand-held handle for holding, the length of the through-end shaft can be shortened by half compared with the prior art, reducing the material for manufacturing the go / no-go gauge, thereby effectively reducing the cost.

[0016] 2. The pass and stop ends are integrated at the same end, and their distinguishing features are obvious, so it is not easy to make a wrong detection.

[0017] 3. Compared with the traditional cylindrical go / no-go gauge, the matching handle designed for this device can effectively prevent rolling through the side plane design, and the cross-sectional size of the handle can be designed to be larger than the outer diameter of the stop sleeve. In this way, after the device is placed on the platform, the outer side wall of the stop sleeve will not contact the platform surface, preventing friction and scratches.

When only the through-end shaft 16 is used for lower limit detection, The backward rotation of the anti-retraction threaded sleeve 11 allows the stop end sleeve 15 to retreat, so that the through-end shaft 16 can be inserted into the hole for inspection. When performing the upper limit detection, the anti-retraction threaded sleeve 11 is rotated forward so that the front end face of the anti-retraction threaded sleeve 11 abuts against the rear end face of the stop end sleeve 15 to limit the position of the stop end sleeve 15. At this time, the front end of the stop end sleeve 15 is flush with the front end of the through-end shaft 16, and the stop end sleeve 15 is stacked on the outside of the through-end shaft 16 and inserted into the hole together for inspection.

[0028] Preferably, the outer side wall of the front sleeve end 13 is also provided with a plurality of stabilizing grooves 14 at annular intervals, which are used for the slide plate 17 to disengage from the engaging groove 20 and then slide into the stabilizing groove 14 when the stop end sleeve 15 slides backward, thereby effectively improving the stability of the stop end sleeve 15.

[0029] Preferably, in order to effectively reduce weight, the front sleeve end 13 is made of steel, and the hand handle 10 can be made of plastic or wood.
