Description

Technical Field

[0001] The utility model relates to a hardness detection device for sheet metal parts, in particular to an auxiliary device for detecting the hardness quality of aircraft sheet metal processing. Background Art

[0002] A hardness tester is a special instrument used to measure surface hardness. Hardness testers are divided into two types: desktop hardness testers and portable hardness testers. Desktop hardness testers are mainly used in laboratories and have the advantage of high precision. Portable hardness testers are suitable for installed machinery or permanent assembly parts and are easy to carry. Existing portable Leeb hardness testers are very effective in testing flat samples, but when testing cylindrical metal samples, it is more difficult to test them due to the uneven surface conditions of the cylindrical surface. During testing, the sample is prone to rolling and deviating, and it is difficult to align the center of the sample for testing. At the same time, during the use of the hardness tester, its connecting harness is only simply connected and does not have an additional reinforcement structure, which makes it easy to detach due to accidents and affect the user's work. In addition, when the user is using the measuring structure for measurement, the portable hardness tester is generally in a placed state. Due to its small display structure, the user needs to pick it up after the measurement to perform subsequent operations, thereby reducing the user's work efficiency and is not conducive to user use. Summary of the Invention

[0006] Two guide grooves are provided on the front and rear side walls of the carrying shell, and the fixing plate is provided with auxiliary components extending out of the two guide grooves of the carrying shell.

[0007] The auxiliary component includes two support rods connected to the fixed plate and extending out of the bearing shell through the guide grooves, and two moving blocks both located outside the inner cavity of the bearing shell and fixedly mounted on the support rods.

[0008] The moving block is fixedly connected with a sliding rod.

[0009] The clamping shell includes an L-shaped carrying plate clamped on the top of the portable hardness testing instrument body and a fixing back plate connected to the side of the carrying plate and capable of fixing the portable hardness testing instrument body.

[0010] The root of the connecting wire harness is located in the inner cavity of the load-bearing shell, and the fixing plate has an arc-shaped inner surface adapted to the outer surface of the root of the connecting wire harness.

[0011] The outer side of the reinforcement rod is fixedly connected with a twisting cover, and the surface of the twisting cover is provided with anti-slip lines.
