Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a part hole depth measuring tool. Background Art

[0002] The hole depth of a part refers to the depth or length of the hole on the part. When manufacturing parts, the hole depth is determined based on design requirements and functional needs. The hole depth is usually used to determine the insertion depth of bolts or other connectors in the part, the channel length inside the hole, etc.

[0003] However, in the prior art, the existing part hole depth measurement method is generally measured by the staff manually, that is, the staff needs to use a measuring cylinder ruler to insert it into the part hole and keep extending it until the measuring cylinder ruler contacts the bottom of the part and cannot extend further. Then the staff records the degree according to the scale number on the measuring cylinder ruler. However, this measurement method requires the staff to work for a long time and increases the workload of the staff. Therefore, the practicality of this measurement method is reduced in actual use. Therefore, we provide a part hole depth gauge. Utility Model Content

[0027] In this embodiment, when the staff uses the present hole depth gauge to measure the part hole, they can place the pressure plate 11 on the outer surface of the part so that the outer surface of the threaded tube 13 is embedded in the part, and then the staff can squeeze the pressure plate 18 so that the pressure plate 18 can be raised and lowered on the balance rod 19, and a measuring tube 17 is provided at one end of the pressure plate 18, and a spring 15, a center rod 14 and a limit pad 16 are respectively provided in the measuring tube 17, so that when the pressure plate 18 applies downward pressure, it can act on the measuring tube 17, and the measuring tube 17 is provided with a spring 15, and the spring 15 will be compressed between the measuring tube 17 and the limit pad 16 during the descent of the measuring tube 17, and the staff only needs to observe the scale number on the outer surface of the measuring tube 17 to measure, thereby improving its practicality in actual use.

[0028] Example 2

[0029] like Figure 1-4As shown, the outer surface of the threaded cylinder 13 is provided with a base mechanism 2, and the base mechanism 2 includes a threaded sub-cylinder 21, and the outer surface of the threaded sub-cylinder 21 is provided with a telescopic sleeve 22, and one end of the telescopic sleeve 22 is provided with a bottom plate 23, and the side of the bottom plate 23 away from the telescopic sleeve 22 is provided with an anti-skid pad 24, and the outer surface of the threaded sub-cylinder 21 is limited in the telescopic sleeve 22 for sliding adjustment, one end of the telescopic sleeve 22 is fixedly connected to the bottom plate 23, and one side of the anti-skid pad 24 is bonded to the side of the bottom plate 23 away from the telescopic sleeve 22.

[0030] In this embodiment, when the staff uses the measuring tool to measure some flat parts, the staff can embed the outer surface of the threaded barrel 13 into the part until the placement plate 11 contacts the part, and then use the threaded sub-barrel 21 to dock with the outer surface of the threaded barrel 13 in a threaded rotation manner, and allow the outer surface of the threaded sub-barrel 21 to be raised and lowered in the telescopic sleeve 22. Finally, the staff only needs to place the base plate 23 with the anti-slip pad 24 on the platform to perform the measurement.

[0031] Working principle:

[0032] like Figure 1-4 As shown, the operator first needs to place the pressure plate 11 of the measuring tool steadily on the outer surface of the part to be measured to ensure that it is in close contact with the part. Then, align the outer surface of the threaded cylinder 13 and insert it into the hole of the part. When measuring, the operator can apply pressure to the pressure plate 18 to adjust it vertically on the balance rod 19. A measuring cylinder 17 is installed at one end of the pressure plate 18, and a spring 15, a center rod 14 and a limit pad 16 are installed inside the measuring cylinder.

[0033] When the operator applies downward pressure to the pressure plate 18, the measuring cylinder 17 is pushed to act on the bottom of the part hole. In this process, the built-in spring 15 will be compressed between the measuring cylinder 17 and the limit pad 16. By reading the scale on the outer surface of the measuring cylinder 17, the operator can intuitively obtain the value of the hole depth.

[0034] For some flat parts, the operator needs to embed the outer surface of the threaded barrel 13 into the part until the pressure plate 11 contacts the surface of the part. In order to achieve accurate measurement, the operator will also use the threaded sub-barrel 21, connect it to the threaded barrel 13 by rotating the thread, and make fine lifting and lowering adjustments of the threaded sub-barrel 21 in the telescopic sleeve 22.

[0035] After completing the above steps, the operator places the base plate 23 with the anti-skid pad 24 on the work platform to ensure stability and accuracy during the measurement process. The entire measuring tool system is designed to provide technicians with a convenient, fast and accurate hole depth measurement method to help them perform quality control in various engineering and manufacturing environments.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
