Description

Technical Field

[0001] The present application relates to the technical field of target material processing, and in particular to a thread inspection tool. Background Art

[0002] Target material, or sputtering target material, is the core material used for thin film preparation. For arc target material, the target material is usually fixed on the base for coating by threaded connection. The end face of the target material is provided with a threaded hole, which is used for the threaded connection of the bolt on the base, so that the target material is fixedly installed on the base, so as to facilitate the coating and other processing procedures of the target material; the threaded hole of the target material must be threadedly matched with the bolt on the base, and there must be no gap. Therefore, the threaded hole as the connection part is the key inspection object in the early stage of target material processing.

[0003] In the prior art, the diameter and depth of the target material threaded hole are generally detected by measuring tools such as vernier calipers so that the various parameters of the threaded hole can match the bolts of the base; however, this type of detection method requires that each parameter of the threaded hole be detected one by one, the operation is cumbersome and the detection efficiency is low, so further improvement is needed.

On the other hand, by observing the fit between the surface of the calibration seat and the end face of the target material, the verticality of the threaded hole of the target material can be determined, so that the diameter, depth and verticality of the threaded hole of the target material can be carried out simultaneously, which greatly improves the detection efficiency of various parameters of the threaded hole of the target material.

The calibration portion 21 and the connecting portion 22 are integrally formed so that one end of the standard plug gauge 2 is connected to the calibration seat 1, and the other end is used to be threadedly connected to the threaded hole 31 of the target material 3.

[0036] Reference Figure 1 A limiting hole 12 is provided on the peripheral wall of the calibration seat 1, and the limiting hole 12 is connected to the connecting hole 11. The calibration seat 1 is provided with a limiting member, and the limiting member is used to limit the connecting part 22 so that the connecting part 22 is fixedly connected to the connecting hole 11; in this embodiment, the limiting member is set as a limiting bolt 4, and the limiting bolt 4 is a hexagon socket bolt.

[0037] The implementation principle of Example 1 of the present application is as follows: when testing the parameters of the threaded hole 31 of the target material 3, rotate the calibration seat 1 so that the calibration part 21 of the standard plug gauge 2 is threadedly connected to the threaded hole 31 of the target material 3, and determine whether the diameter of the threaded hole 31 is standard by observing the threaded fit between the calibration part 21 and the threaded hole 31.

[0038] Embodiment 2:

[0039] The embodiment of the present application discloses a thread inspection tool.

[0040] Reference Figure 2 The difference between the thread inspection tool disclosed in the embodiment of the present application and the embodiment 1 is that:

[0041] In this embodiment, an adjustment hole 13 is opened on the bottom wall of the connecting hole 11, and the adjustment hole 13 passes through the surface of the calibration seat 1 away from the target material 3. An adjustment member 8 is installed between the connecting hole 11 and the adjustment hole 13. The adjustment member 8 is used to adjust the depth of the connecting part 22 inserted into the connecting hole 11, thereby being able to adjust the depth of the calibration part 21 entering the threaded hole 31 of the target material 3.

[0042] Reference Figure 2 The adjusting member 8 includes an adjusting block 81 and an adjusting rod 82. The adjusting block 81 is installed in the connecting hole 11. One end of the adjusting rod 82 is fixedly connected to the side wall of the adjusting block 81 away from the connecting portion 22, and the other end passes through the adjusting hole 13 and extends to the side of the calibration seat 1 away from the target material 3. In this embodiment, the adjusting rod 82 is threadedly connected to the adjusting hole 13, and the adjusting block 81 is slidably installed in the connecting hole 11 through the adjusting rod 82 and can slide along the axial direction of the connecting hole 11.

[0043] Reference Figure 2 A recessed groove 822 is formed on the peripheral wall of the adjusting rod 82 , and both ends of the recessed groove 822 are extended along the axial direction of the adjusting rod 82 . A scale line 821 is formed on the bottom wall of the recessed groove 822 , and the length direction of the scale line 821 is consistent with the axial direction of the adjusting rod 82 .

[0044] The implementation principle of Example 2 of the present application is: rotating the adjusting rod 82 forces the adjusting block 81 to slide axially along the connecting hole 11, so as to adjust the depth of the connecting hole 11, thereby controlling the depth of the connecting part 22 inserted into the connecting hole 11, and then adjusting the distance between the end of the calibration part 21 away from the connecting part 22 and the surface of the calibration seat 1, so that the calibration part 21 can detect the threaded holes 31 of the target material 3 with different depth requirements, thereby improving the adaptability of the overall structure.

The limit ring 5 is ring-shaped around the circumference of the calibration seat 1, and the rotation center axis of the limit ring 5 is consistent with the axial direction of the calibration seat 1; a limit groove 51 is provided on the inner circumferential wall of the limit ring 5, and the limit groove 51 is an annular groove, and the limit hole 12 is connected to the limit groove 51.

When the limiting ring 5 rotates, the pushing arc surface 71 is used to push the limiting rod 6 so that the limiting rod 6 gradually approaches the connecting hole 11; and when one end of the limiting rod 6 moves to the abutting surface 72, the limiting rod 6 is pressed against the connecting portion 22 and limits the circumferential rotation of the limiting ring 5.

[0050] Reference Figure 3 , Figure 4 An abutment ring 61 is fixedly installed on the outer peripheral wall of the limiting rod 6, and the limiting rod 6 is provided with an elastic reset member. In this embodiment, the elastic reset member is a reset spring 9, one end of the reset spring 9 is fixedly connected to the inner wall of the limiting hole 12, and the other end of the reset spring 9 is fixedly connected to the abutment ring 61. The reset spring 9 normally causes the limiting rod 6 to be separated from the connecting portion 22, that is, the reset spring 9 normally causes the end of the limiting rod 6 close to the connecting hole 11 to move into the limiting hole 12.

[0051] The implementation principle of Example 3 of the present application is as follows: when the standard plug gauge 2 is installed, the connecting part 22 is inserted into the connecting hole 11, and then the limit ring 5 is driven to rotate, and the limit ring 5 drives the guide block 7 to rotate, and the arc surface 71 is pushed to push the limit rod 6 toward the connecting hole 11, and the limit ring 5 is continuously rotated to make the abutment surface 72 abut against the limit rod 6. At this time, the limit rod 6 is tightly pressed against the peripheral wall of the connecting part 22, and the limit rod 6 and the abutment surface 72 are tightly pressed against each other to limit the limit ring 5 and reduce the possibility of free rotation of the limit ring 5; when disassembling, a certain rotational force is applied to the limit ring 5, so as to drive the guide block 7 to disengage from the limit rod 6, and the limit rod 6 is disengaged from the connecting part 22 under the action of the reset spring 9, thereby improving the convenience of disassembly and assembly of the standard plug gauge 2.
