Description

Technical Field

[0001] This utility model relates to the field of testing tools, specifically a simple position measurement tool. Background Technology

[0002] In the machinery manufacturing industry, the positional accuracy and diameter of holes in parts are crucial quality indicators, directly affecting product assembly performance and service life. Traditional methods for hole positional accuracy inspection typically employ precision measuring equipment such as coordinate measuring machines (CMMs), which are costly, complex to operate, and unsuitable for rapid on-site inspection. While simpler methods, such as using plug gauges or calipers, are easy to operate, their accuracy is low and cannot effectively guarantee part quality. Therefore, there is a need for a simple, easy-to-operate, low-cost inspection tool that can quickly and accurately inspect the positional accuracy and diameter of holes in parts.

[0003] Therefore, this application proposes a simple position measurement tool that is simple in structure, easy to operate, low in cost, and can quickly and accurately detect the position and diameter of holes in parts. Utility Model Content

[0004] Purpose of the utility model: To solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A simple position gauge, comprising a testing seat and a go gauge, including:

[0007] The testing seat is a rigid structure with at least two through holes on its surface. The positions of the through holes are the same as the corresponding holes on the part being tested, and the diameter of the through holes is slightly larger than the theoretical diameter of the corresponding holes on the part being tested to allow the go gauge to pass freely. The bottom surface of the testing seat is provided with a positioning structure for accurately positioning the part being tested. The positioning structure includes, but is not limited to, positioning pins, positioning blocks, or V-grooves. The positioning structure cooperates with the reference surface or reference hole on the part being tested to ensure the positional accuracy of the part being tested on the testing seat.

[0008] The number of gauges is the same as the number of through holes on the testing seat, with each gauge corresponding to one through hole; the gauges are cylindrical with a diameter slightly smaller than the minimum allowable diameter of the corresponding hole on the part being tested, in order to detect the lower limit of the hole diameter; the length of the gauges is greater than the thickness of the testing seat, to ensure that the gauges can completely pass through the holes on the part being tested; the surface of the gauges is precision ground to ensure their dimensional accuracy and surface finish.

[0009] Furthermore, the bottom positioning structure of the detection seat is a positioning pin, which is fixed to the detection seat by threaded connection or interference fit, and the end of the positioning pin is conical or cylindrical to facilitate the positioning of the part being tested.

[0010] Furthermore, the bottom positioning structure of the detection seat is a positioning block, which is fixed to the detection seat by screws or welding, and the surface of the positioning block is hardened to improve wear resistance.

[0011] Furthermore, the bottom positioning structure of the detection seat is a V-groove with an included angle of 90 degrees or 120 degrees, used to position cylindrical or spherical parts.

[0012] Furthermore, the handle end of the go gauge is provided with anti-slip texture.

[0013] Furthermore, the detection seat is made of a high-strength wear-resistant material, which is alloy steel, hard alloy or engineering plastic, and the surface of the detection seat is treated by quenching, carburizing or hard chrome plating to improve its hardness and wear resistance.

[0014] Furthermore, the gauge is made of tool steel or bearing steel and is hardened to achieve a hardness of HRC58-62 to ensure its wear resistance and dimensional stability.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The inspection fixture in this application has a simple structure, mainly composed of an inspection seat and a go gauge. It is easy to manufacture and has low cost. Operators only need to place the part to be tested on the inspection seat and then use the go gauge for inspection. The operation is simple and the inspection speed is fast. The accuracy of the inspection can be guaranteed by the precise position of the through hole on the inspection seat and the precise size of the go gauge. Whether the go gauge can pass smoothly through the hole of the part being tested can be used to determine whether the position of the hole is qualified. The diameter of the go gauge can be used to determine whether the diameter of the hole is within the allowable range. Through inspection, unqualified parts can be detected in time, preventing them from entering the assembly process and ensuring the quality and reliability of the product. Attached Figure Description

[0023] Applicant's design Figure 1 The illustrated simple position gauge includes a testing seat 1 and a go gauge 3, comprising:

[0024] The testing seat 1 is a rigid structure with at least two through holes 2 on its surface. The positions of the through holes 2 are the same as the corresponding holes on the part being tested 5, and the diameter of the through holes 2 is slightly larger than the theoretical diameter of the corresponding holes on the part being tested 5 to allow the gauge 3 to pass freely. The bottom surface of the testing seat 1 is provided with a positioning structure for accurately positioning the part being tested 5. The positioning structure includes, but is not limited to, a positioning pin 41, a positioning block 42, or a V-groove 43. The positioning structure cooperates with the reference surface or reference hole on the part being tested 5 to ensure the positional accuracy of the part being tested 5 on the testing seat 1.

[0025] The number of gauges 3 is the same as the number of through holes 2 on the inspection seat 1, with each gauge 3 corresponding to one through hole 2; the gauge 3 is a cylindrical structure, and its diameter is slightly smaller than the minimum allowable diameter of the corresponding hole on the part being measured 5, so as to detect the lower limit of the hole diameter; the length of the gauge 3 is greater than the thickness of the inspection seat 1 to ensure that the gauge 3 can completely pass through the hole on the part being measured 5; the surface of the gauge 3 is precision ground to ensure its dimensional accuracy and surface finish.

[0026] The handle end of the go gauge 3 is provided with anti-slip texture; the test seat 1 is made of high-strength wear-resistant material, which is alloy steel, hard alloy or engineering plastic, and the surface of the test seat 1 is quenched, carburized or hard chrome plated to improve its hardness and wear resistance; the go gauge 3 is made of tool steel or bearing steel and is quenched to achieve a hardness of HRC58-62 to ensure its wear resistance and dimensional stability. Example

[0027] like Figure 2 In this embodiment of the simplified position gauge, the bottom positioning structure of the detection seat 1 is a positioning pin 41. The positioning pin 41 is fixed on the detection seat 1 by threaded connection or interference fit, and the end of the positioning pin 41 is conical or cylindrical to facilitate the positioning of the part 5 to be measured. Example

[0028] like Figure 3In this embodiment of the simplified position gauge, the bottom positioning structure of the detection seat 1 is a positioning block 42. The positioning block 42 is fixed to the detection seat 1 by screws or welding, and the surface of the positioning block 42 is hardened to improve wear resistance. Example

[0029] like Figure 4 In this embodiment, the simple position gauge further includes a bottom positioning structure of the detection seat 1 as a V-groove 43, with an included angle of 90 degrees or 120 degrees, used to position cylindrical or spherical parts 5.

[0030] How to use:

[0031] 1. Place the part to be tested 5 on the test seat 1 and position it precisely using the positioning pin 41, positioning block 42 or V-groove 43.

[0032] 2. Insert the three gauges 3 into the two through holes 2 on the test seat 1 respectively.

[0033] 3. Observe whether the gauge 3 can pass smoothly through the hole of the part being tested 5.

[0034] 4. If all gauges 3 can pass smoothly through the hole of the tested part 5, it means that the position and diameter of the hole of the tested part 5 are qualified; otherwise, it means that the position or diameter of the hole of the tested part 5 is unqualified.
