Description

Technical Field

[0001] The utility model relates to the technical field of nut forming hole testing jigs, in particular to a verticality inspection jig. Background Art

[0002] In the existing technology, the verticality of the nut forming hole will be 100% transferred to the tapping process. Currently, there are special tools to detect the verticality of the nut after tapping, but there is no detection tooling for the verticality of the hole diameter during nut forming, and the product yield cannot be guaranteed. Utility Model Content

[0003] The purpose of the present invention is to provide a verticality inspection jig to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a verticality inspection fixture, including a test base, wherein the end surface of the test base is symmetrically provided with multiple guide columns, multiple guide columns are provided with sliders, multiple guide columns are provided with conical columns in the middle, and detection nuts are provided on the conical columns.

[0005] For further optimization, a tapered hole for sliding through the tapered column is provided in the middle of the slider.

[0006] For further optimization, the sliding block is symmetrically provided with through holes around the tapered hole and penetrated by multiple guide columns.

[0007] Further optimized, the clearance between the detection nut and the slider is the verticality of the tapered hole.

[0008] For further optimization, the upper portion of the conical column is provided with a taper.

[0009] For further optimization, two of the guide columns are provided with positioning devices at their upper ends.

[0010] Beneficial effects

[0011] The verticality inspection jig provided by the utility model has a simple tooling structure, is easy to operate, and has high inspection efficiency. The tooling head adopts a conical structure, and several apertures can share a set of inspection tools, which effectively reduces the inspection cost and ensures the verticality yield rate of the nut aperture.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] Example

[0016] like Figure 1-2 As shown, a verticality inspection fixture includes a test base 1, a plurality of guide columns 3 are symmetrically provided on the end surface of the test base 1, a slider 2 is provided on the plurality of guide columns 3, a tapered column 5 is provided in the middle of the plurality of guide columns 3, and a detection nut 4 is provided on the tapered column 5.

[0017] In this embodiment, a tapered hole is opened in the middle of the slider 2 for sliding through the tapered column 5; the slider 2 is symmetrically provided with through holes opened through multiple guide columns 3 around the tapered hole; the gap between the detection nut 4 and the slider 2 is the verticality 6 of the tapered hole.

[0018] The upper portion of the tapered column 5 is provided with a taper.

[0019] Two of the guide posts 3 are provided with positioning devices at their upper ends.

[0020] The upper part of the tapered column is tapered to ensure that the nut hole is concentric with the tapered column;

[0021] The tapered column and tapered structure can meet the needs of multiple specifications by sharing one tooling, ensuring the versatility of the tooling and reducing costs;

[0022] The slider slides along the four sliding columns to ensure that the slider is perpendicular to the tapered column;

[0023] The positioning devices on the two symmetrical sliding columns can quickly lock the height of the slider to ensure the correct contact position between the slider and the test nut ground.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
