[0035] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection in the claims of the present application can be implemented.

[0036] The first embodiment of the present invention relates to a spring detection tool, such as Figure 1 As shown, first, in this embodiment, the spring 1 to be tested includes: a first spiral section 11 arranged along the first axial direction, a first extension section 12 extending horizontally from one end of the first spiral section 11, a first pin 13 extending horizontally from the other end of the first spiral section 11, a second spiral section 14 arranged along the second axial direction, a second extension section 15 extending horizontally from one end of the second spiral section 14, a second pin 16 extending horizontally from the other end of the second spiral section 14, and an inclined section 17 connected to the first extension section 12 and the second extension section 15, respectively. In this embodiment, the first axial direction and the second axial direction are arranged parallel to each other, and the first extension section 12, the inclined section 17 and the second extension section 15 form a clamping portion with a concave area 18.

[0037] In addition, the detection tooling of this embodiment, such as Figure 3 As shown, it includes: a base plate 2, a first cylinder 3, a second cylinder 4, a third cylinder 5, a first detection mechanism 6 and a second detection mechanism 7.

[0038] Among them, Figure 3 As shown, the bottom plate 2 has a detection plane 21 , and the first cylinder 3 , the second cylinder 4 and the third cylinder 5 are all vertically arranged on the detection plane 21 .

[0039] Secondly, if Figure 3As shown, the first detection mechanism 6 is arranged on the detection plane 21 and is opposite to the first cylinder 3. In addition, the first detection mechanism 6 includes: a first positioning block 61 arranged on the detection plane 21, a first slider 62 inserted in the first positioning block 61, the first slider 62 is slidable relative to the first cylinder 3, and at the same time, the first slider 62 has an opening 621 at one end relative to the first cylinder 3, and the opening 621 has a first reference surface 6231 and a second reference surface 6241 opposite to the first reference surface 6231 along a direction parallel to the detection plane 21.

[0040] In addition, if Figure 3 As shown, the second detection mechanism 7 is arranged on the detection plane 21 and is opposite to the second cylinder 4. At the same time, the second detection mechanism 7 includes: a second positioning block 71 arranged on the detection plane 21, a second slider 72 inserted into the second positioning block 71, the second slider 72 can slide along the tangent direction of the second cylinder 4, and the second slider 72 has a detection protrusion 721 at one end relative to the second cylinder 4.

[0041] In actual detection, first, when the first spiral section 11 or the second spiral section 14 of the spring 1 is sleeved on the first cylinder 3, the first slider 62 slides relative to the first cylinder 3, so that the opening 621 on the first slider 62 can detect the distance between the first pin 13 and the second pin 16, that is, when the first pin 13 and the second pin 16 can enter the opening 621, combined with Figure 3 and Figure 4 As shown, it means that the distance between the first pin 13 and the second pin 16 meets the assembly requirements, otherwise it does not meet the assembly requirements. Secondly, when the first spiral section 11 or the second spiral section 14 of the spring 1 is sleeved on the second cylinder 4, the second slider 72 can detect the distance between the first extension section 12 and the second extension section 15 by sliding the second slider 72 along the tangent direction of the second cylinder 4. That is, when the detection protrusion 721 of the second slider 72 can pass through the clamping portion with the concave area 18 formed by the first extension section 12, the inclined section 17 and the second extension section 15, combined with Figure 3 and Figure 5 As shown, it means that the distance between the first extension section 12 and the second extension section 15 meets the assembly requirements, otherwise it does not meet the assembly requirements. Finally, when the first spiral section 11 of the spring 1 is sleeved on the third cylinder 5, the inner diameter of the first spiral section 11 can be detected through the third cylinder 5, and when the second spiral section 14 is sleeved on the third cylinder 5, the inner diameter of the second spiral section 14 can be detected through the third cylinder 5, that is, when the first spiral section 11 and the second spiral section 14 can be sleeved on the third cylinder 5, it means that the inner diameters of the first spiral section 11 and the second spiral section 14 meet the assembly requirements, otherwise they do not meet the assembly requirements.

[0042] It is not difficult to see from the above content that the spring inspection tool of this embodiment can greatly improve the inspection efficiency and reduce the inspection cost because it can simultaneously detect various key dimensions of the spring.

[0043] Specifically, in this embodiment, if Figure 3 and Figure 4 As shown, the first positioning block 61 opens a first slideway (not shown) for the first slideway 62 to pass through along the sliding direction of the first slideway 62. At the same time, in this embodiment, the first slideway 62 includes: a first sliding section 621 passing through the first slideway, a first reference block 623 and a second reference block 624 arranged at one end of the first sliding section 622 relative to the first cylinder 3, and the first reference block 623 and the second reference block 624 are spaced apart from each other along a direction parallel to the detection plane to form an opening 621. The side of the first reference block 623 relative to the second reference block 624 is a first reference surface 6231, and the side of the second reference block 624 relative to the first reference block 623 is a second reference surface 6241. And, as a preferred solution, in some embodiments, the first reference block 623 and the second reference block 624 are slidable relative to each other, so that the first detection mechanism 6 can meet the detection requirements of springs of different sizes.

[0044] In addition, if Figure 3 and Figure 5 As shown, the second positioning block 71 opens a second slideway (not shown) along the sliding direction of the second slider 72 for the second slider 72 to pass through. Through the cooperation between the second slideway and the second slider 72, the second slider 72 can slide along the tangential direction of the second cylinder 4 to ensure that the detection protrusion 721 can detect the distance between the first extension section 12 and the second extension section 15.

[0045] In addition, it is worth mentioning that in the process of practical application, Figure 3 As shown, the first detection mechanism 6 further includes: a first locking member 63. The first locking member is disposed on a side of the first positioning block 61 away from the detection plane 21 and is threadedly connected to the first positioning block 61, so that the first locking member 63 can be directly screwed into the first slideway when the first slider 62 slides to a predetermined position to lock and fix the first slider 62. Similarly, Figure 3As shown, the second detection mechanism 7 also includes: a second locking member 73, which is arranged on the side of the second positioning block 71 away from the detection plane 21, and is threadedly connected to the second positioning block 71, so that the second locking member 73 can be directly screwed into the second slideway when the second slider 72 slides to a predetermined position, and the second slider 72 is locked and fixed. It is not difficult to see that the first slider 62 and the second slider 72 can be locked by means of the first locking member 63 and the second locking member 73, and it should be noted that the first locking member 63 and the second locking member 73 are both bolts in this embodiment. Of course, in actual application, the first locking member 63 and the second locking member 73 can also use other locking members, and in this embodiment, the structure of the first locking member 63 and the second locking member 73 is not specifically limited.

[0046] In addition, as a preferred solution, in the present embodiment, the first slider 62 is provided with a scale (not shown in the figure) along its sliding direction, and the length of the first stitch 13 and the second stitch 16 can be detected by the scale. It should be noted that the scale is a plurality of scale lines arranged on the first slider 62 along the sliding direction of the first slider 62.

[0047] In addition, it is worth mentioning that, in this embodiment, in order to facilitate the detection of the sizes of the various pipes of the spring 1, the first cylinder 3, the second cylinder 4 and the third cylinder 5 can be movably arranged on the detection plane 21 of the bottom plate 2. Specifically, in this embodiment, combined with Figure 6 As shown, a plurality of threaded holes 22 are distributed on the detection plane 21. In addition, the first cylinder 3 includes: a first positioning section 31, a first threaded section 32 connected to the first positioning section 31, and the first threaded section 32 is used to screw into any threaded hole 22. Secondly, the second cylinder 4 includes: a second positioning section 41, a second threaded section 42 connected to the second positioning section 41, and the second threaded section 42 is used to screw into any threaded hole 22. Finally, the third cylinder 5 includes: a third positioning section 51, a third threaded section 52 connected to the third positioning section 51, and the third thread 52 is used to screw into any threaded hole 22. In addition, the outer diameters of the first threaded section 32, the second threaded section 42 and the third threaded section 52 are all the same. Therefore, it is not difficult to see that in actual application, the first cylinder 3, the second cylinder 4 and the third cylinder 5 can be selectively screwed with any threaded hole 22 on the detection plane 21 according to the measurement requirements of the spring 1, so that it can meet the measurement requirements of more sizes.

[0048] In addition, as a preferred solution, in some embodiments, the first positioning section 31, the second positioning section 41 and the third positioning section 51 are all retractable in a direction perpendicular to the detection plane 21. This can meet the requirements for the installation of springs of different heights.
