Description

Technical Field

[0001] This utility model belongs to the field of measuring devices characterized by mechanical technology, specifically a plug gauge tooling for detecting connector holes in machining. Background Technology

[0002] In modern machining industries, connectors are widely used in various electronic devices, automobile manufacturing, and other fields, and their quality directly affects product performance and reliability. Connector holes, as a critical structure of connectors, have stringent requirements for dimensional accuracy. Currently, there are many problems with the testing methods for connector holes.

[0003] Traditional inspection methods are inefficient: the conventional approach involves removing the workpiece from the machine tool and using large equipment such as a coordinate measuring machine for inspection. This method not only consumes a significant amount of time in disassembling, handling, and reclamping the workpiece, but the frequent loading and unloading operations can also lead to workpiece positioning errors, affecting the accuracy of the inspection results. Statistics show that each inspection using traditional methods takes approximately 0.5 hours, severely impacting production efficiency.

[0004] The testing tools are limited in function: Existing testing tools can often only test one dimension of the connector hole, such as length or width. For comprehensive testing that includes length, width and corner radius, multiple different testing tools are required, which increases testing costs and operational complexity.

[0005] Therefore, developing a testing fixture that can quickly and accurately detect whether the dimensions of connector holes are within tolerance is of great practical significance. Utility Model Content

[0032] The testing process is as follows:

[0033] When it is necessary to check whether the through hole 301 of the part under test is qualified, the through hole 301 of the part under test is placed with the part under test facing upward in the center groove of the base of the placement platform 2. The through hole gauge 111 is selected and slowly inserted into the through hole 301 that has just been machined through the positioning frame 201. When the bottom plane of the through hole connecting post 112 of the through hole gauge 1 contacts the bottom of the inner positioning groove 203, it proves that the actual size of the through hole 301 is greater than the minimum limit size, so the through hole 301 of the part under test is qualified; if it cannot be fully inserted, it is unqualified.

[0034] Flip the through hole gauge 1 so that the through hole stop gauge 113 passes through the positioning frame 201 and is slowly inserted into the through hole 301 to be tested. If it cannot be inserted, it proves that the actual size of the through hole 301 to be tested is less than the maximum limit size, and the machining size of the through hole 301 to be tested is qualified.

[0035] In this embodiment, since there are three dimensions to be tested, in addition to testing the through hole 301, the middle test groove 302 and the outer test groove 303 also need to be tested.

[0036] The inspection process for the middle side groove 302 and the outer side groove 303 using the middle side groove gauge 11 and the outer side groove gauge 12 respectively is as follows:

[0037] Place the part to be tested 3 with the middle side test groove 302 facing upward in the center groove of the base of the placement table 2. Use the middle side groove gauge 12 to slowly insert the middle side groove gauge 121 through the positioning frame 201 into the newly machined middle side test groove 302. When the bottom plane of the middle side groove connecting column 122 of the middle side groove gauge 12 contacts the bottom of the middle side positioning groove 204, it proves that the actual size of the middle side test groove 302 is greater than the minimum limit size, so the middle side test groove 302 of the part to be tested 3 is qualified; if it cannot be fully inserted, it is unqualified.

[0038] Flip the middle side groove gauge 12 so that the middle side groove stop gauge 123 passes through the positioning frame 201 and is slowly inserted into the middle side groove 302 to be tested. If it cannot be inserted, it proves that the actual size of the middle side groove 302 to be tested is smaller than the maximum limit size, and the machining size of the first groove 302 to be tested is qualified.

[0039] Place the outer test groove 303 of the part to be tested 3 facing upwards in the center groove of the base of the placement table 2. Select the outer groove gauge 13 to slowly insert the outer groove gauge 131 through the positioning frame 201 into the newly machined outer test groove 303. When the bottom plane of the outer groove connecting post 132 of the outer groove gauge 13 contacts the bottom of the outer positioning groove 205, it proves that the actual size of the outer test groove 303 is greater than the minimum limit size, so the outer test groove 303 of the part to be tested 3 is qualified; if it cannot be fully inserted, it is unqualified.

[0040] Flip the outer groove gauge 13 so that the outer groove stop gauge 133 passes through the positioning frame 201 and is slowly inserted into the outer groove 303 to be tested. If it cannot be inserted, it proves that the actual size of the outer groove 303 to be tested is less than the maximum limit size, and the machining size of the second groove 303 to be tested is qualified.
