Embodiment Construction
[0024] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0025] Such as figure 1 As shown, a strength testing tool based on irregular weld seams of structural parts, the structural part to be tested includes a vertically connected first body 601 and a second body 602 with holes, and is characterized in that it includes a clamping mechanism 1 and Workbench 2;
[0026] The clamping mechanism 1 includes a C-shaped clamp 101 and a fastener 102. One end of the inner side of the C-shaped clamp is close to the lower end surface of the workbench 2, and the other end is rotatably connected to the fastener 102. The fastener 102 is connected to the The workbench 2 cooperates to fix the first body 601 on the workbench 2;

Abstract
The invention discloses a strength detection tool and method based on an irregular weld joint of a structural member, and the detected structural member comprises a first body and a second body whichare vertically connected, and also comprises a clamping mechanism and a workbench. The clamping mechanism comprises a C-shaped clamp and a fastener, one end of the inner side of the C-shaped clamp istightly attached to the lower end face of the workbench, the other end of the inner side of the C-shaped clamp is rotationally connected with the fastener, and the fastener is matched with the workbench to fix the first body to the workbench; the clamping mechanism further comprises a bolt and a nut. The bolt is used for penetrating through the hole of the second body, the bottom end of the bolt acts on the workbench, and the nut is screwed down from the upper side of the second body for pre-tightening; and the nut is used for testing the tightening torque of a tested tool. The tool is compactand simple in structure, wide in application range, capable of achieving testing through one torque wrench or one torque tester, low in cost, easy to operate and capable of achieving nondestructive testing.
Description
technical field [0001] The invention discloses a strength detection tool and method based on irregular weld seams of structural parts, and relates to the technical field of weld seam performance detection. Background technique [0002] At this stage, irregular welds such as T-shape and L-shape are common in many structural parts. In the prior art, it is only for the detection of fillet weld samples, but for the strength detection of irregular welds of structural parts, the quality of welds is mainly judged by metallographic analysis of joints, but the metallographic analysis process is cumbersome and requires higher. However, conventional mechanical performance testing cannot meet the test of irregular weld strength of structural parts. Therefore, there is an urgent need for a strength detection tool and method based on irregular welds of structural parts to solve the problem of strength detection of irregular welds. Contents of the invention [0003] Aiming at the defe...
