Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0039] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0040] This application provides a tear strength testing fixture, referring to... Figures 1 to 3 The tear strength testing fixture includes a fixture body 1 for placing the welded component to be tested. The welded component includes a first part 01 and a second part 02 welded to the first part 01. The first part 01 and the second part 02 are arranged sequentially along a first direction, which is parallel to the direction of the tensile force during the tear strength test. A pull clamp handle 11 is connected to the bottom of the fixture body 1 and is connected to a first tensile testing device through the pull clamp handle 11. The end of the second part 02 away from the first part 01 serves as a clamping end 021 connected to the second tensile testing device. For the welded component, when both hard and soft materials are present, the soft material is designated as the first part 01. The first tensile testing device and the second tensile testing device are arranged sequentially along the first direction. During the tensile test, the first tensile testing device and the second tensile testing device apply tensile force in opposite directions. In this embodiment, the first tensile testing device and the second tensile testing device are the lower clamp and the upper clamp on a tensile testing machine.
[0041] Reference Figures 1 to 3The tooling body 1 is equipped with a first fixing component 2, a second fixing component 3, and a third fixing component 4. The first fixing component 2 is used to fix the first component 01 in a second direction perpendicular to the first direction; the second fixing component 3 is used to fix the first component 01 in the first direction; and the third fixing component 4 is used to press the end of the second component 02 away from the clamping end 021 in the first direction. During tear strength testing, the first fixing component 2 and the second fixing component 3 simultaneously fix and limit the first component 01, reducing the possibility of deformation and twisting of the first component 01. Simultaneously, when the second pulling device pulls the clamping end 021 of the second component 02, the third fixing component 4 presses the end of the second component 02 away from the clamping end 021 in the first direction, reducing the possibility of displacement of the second component 02 during the pulling process, i.e., the possibility of the second component 02 being pulled at an angle.
[0042] Furthermore, in this embodiment, the first direction is set along the vertical direction and the second direction is set along the horizontal direction as an example for explanation.
[0043] Reference Figures 1 to 3 A sliding groove 12 is formed on the upper surface of the tooling body 1 along a second direction, and a supporting slider 5 is provided on the tooling body 1. The lower end of the supporting slider 5 is slidably engaged with the sliding groove 12, allowing the supporting slider 5 to slide along the second direction. The supporting slider 5 is used to support one end of the first component 01, and a protrusion 51 for limiting the first component 01 is provided on the supporting slider 5. The first fixing assembly 2 includes a first driving member 21 and a fixing plate 22, and the fixing plate 22 and the protrusion 51 on the supporting slider 5 are arranged opposite to each other. The first driving member 21 is used to push the supporting slider 5 to slide along the sliding groove 12, and the fixing plate 22 is used to abut against the end of the first component 01 away from the supporting slider 5. When testing is required, the first component 01 of the welded part is placed on the upper surface of the supporting slider 5, so that one end of the first component 01 is held in place by the supporting slider 5. Then, by adjusting the first driving component 21, the supporting slider 5 drives the first component 01 to gradually approach the fixing plate 22, and finally it is pressed against the fixing plate 22, thereby fixing the first component 01 in the second direction. To improve the fixing effect, the end face of the fixing plate 22 that presses against the end of the first component 01 can be set to a serrated shape, such as... Figure 1 As shown.
[0044] Reference Figures 1 to 3The first driving component 21 includes a first rotating shaft threadedly connected to the tooling body 1, and the first rotating shaft is arranged along the length direction of the sliding groove 12. The first rotating shaft can be a T-shaped lead screw, in which case the nut of the first rotating shaft is bolted to the tooling body 1, thereby improving the connection stability. One end of the first rotating shaft is located inside the sliding groove 12 and rotatably connected to the lower end of the supporting slider 5, and the other end of the first rotating shaft is located outside the sliding groove 12 and connected to a handle. The position of the supporting slider 5 can be adjusted by rotating the handle.
[0045] Reference Figures 1 to 3 The second fixing component 3 includes a pressure plate 31 for pressing the first component 01 in a first direction. One end of the pressure plate 31 is hinged to the supporting slider 5, and the other end is connected to the supporting slider 5 via a locking member 32. The plane of the rotation path of the pressure plate 31 is parallel to the first direction. The locking member 32 can be a pin, with corresponding slots on the pressure plate 31 and the supporting slider 5 for engaging with the pin. After rotating the pressure plate 31 to the position pressing the first component 01, aligning and inserting the pin into the slots on the supporting slider 5 and the pressure plate 31 secures the pressure plate 31. Figure 1 In the middle, the pressure plate 31 presses down on the first component 01, but does not press down on the second component 02.
[0046] Furthermore, in order to reduce the possibility of the locking element 32 being lost, refer to Figure 1 An anti-loss chain 6 is connected to the locking member 32. The other end of the anti-loss chain 6 can be connected to the first tension device. In other embodiments, it can also be connected to the tooling body 1 or other positions.
[0047] Reference Figure 1 and Figure 3 The third fixing component 4 includes a rotating arm 41, a pressure plate 42, and a second driving member 43. One end of the rotating arm 41 is hinged to the vertical side wall of the tooling body 1, and the plane of the rotation path of the rotating arm 41 is parallel to the first direction, meaning the rotating arm 41 can reciprocate in a vertical plane. The pressure plate 42 is fixedly connected to the end of the rotating arm 41 away from the hinge point with the tooling body 1. The second driving member 43 is connected to the tooling body 1 and is used to push the pressure plate 42 to move, thereby pressing or releasing the end of the second component 02 away from the clamping end 021.
[0048] Furthermore, refer to Figures 1 to 3The second driving component 43 includes a second rotating shaft, and a mounting block 13 extends from the top of the tooling body 1. The second rotating shaft is threadedly connected to the mounting block 13. The length direction of the second rotating shaft is parallel to the plane of the rotation path of the rotating arm 41. One end of the second rotating shaft abuts against the pressure plate 42, and the other end is connected to a handle. Rotating the handle will cause the second rotating shaft to rotate, thereby pressing or releasing the pressure plate 42. When the pressure plate 42 is pressed and pushed, the pressure plate 42 can be pressed against the second component 02.
[0049] This application discloses a tear strength testing fixture, comprising a fixture body 1, a first fixing component 2, a second fixing component 3, and a third fixing component 4. When a tensile test is required, the fixture body 1 is installed onto a first tensile testing device, and the welded part is placed on the fixture body 1. Then, the first fixing component 2 and the second fixing component 3 clamp and fix the first component 01 of the welded part, and the third fixing component 4 clamps and fixes the second component 02 of the welded part. Finally, the clamping end 021 of the second component 02 is connected to the second tensile testing device to perform the tear strength test. The presence of the first fixing component 2, the second fixing component 3, and the third fixing component 4 reduces the possibility of deformation or displacement of the welded part during the tear strength test, thus improving the reliability of the test results.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
