Description

Technical Field

[0001] The utility model relates to a tool, in particular to an anti-deformation tool used for a welding material re-inspection test plate. Background Art

[0002] When retesting welding materials, welding groove surfacing is often required. Due to the large gap and large amount of welding materials, welding deformation will be very serious. The deformation of the welding test plate during welding in a free state is as follows: Figure 10 As shown. However, after welding, the test plate is typically required to have minimal deformation, facilitating removal of the backing plate and nondestructive testing. Therefore, the conventional solution is to add reinforcing ribs to the back of the test plate and secure it by welding to prevent deformation. However, this method wastes steel plates when retesting large quantities of welding materials, as most are disposable after a single use. Furthermore, the workload of welding and subsequent rib removal and grinding is enormous.

[0003] Therefore, it is urgent to develop an anti-deformation tooling for welding material re-inspection test plates. This anti-deformation tooling can meet the welding material re-inspection requirements of most materials. It can also be reused multiple times and is easy to operate. Utility Model Content

The clamping screw is threadedly connected to the end cap, and the loosening screw is mounted on the end cap via a nut. The first slider has a mounting hole, and the loosening screw is fixedly mounted in the mounting hole.

[0008] In one embodiment of the present invention, the first sliding block includes a wedge-shaped portion and a connecting portion, the wedge-shaped portion and the connecting portion are fixedly connected, the connecting portion is located on the support platform, and the wedge-shaped portion is located above the second sliding block.

[0010] In one embodiment of the present invention, the cross-section of the holding slider is T-shaped.

[0011] In one embodiment of the present invention, the upper end surface of the second sliding block is an inclined surface.

[0012] A deformation-preventing fixture for welding material retest plates comprises the aforementioned clamping mechanism, wherein the clamping arms are located in pairs on the upper portion of the clamp body, the clamp body further comprising a backing plate slot located in the middle of the clamp body, and the retest plate is mounted between the clamping arms and the clamp body.

[0013] In one embodiment of the present invention, the distance between the clamp arm and the clamp body is 14-28 mm.

DETAILED DESCRIPTION

[0031] Below with reference to the embodiment and the attached Figures 1 to 9 The utility model is further described.

[0032] An anti-deformation tool for welding material re-inspection test plate, such as Figure 1-3 As shown, it is composed of a pair of clamping mechanisms, and the pair of clamping mechanisms are fixedly connected together by a guide rail. The clamping mechanism includes a clamp body 100, a first slider 1, a second slider 2, a slider cover 3, a tightening screw 4 and a loosening screw 5. A clamping arm 6 extends from the clamp body, and there is a gap between the clamping arm and the clamp body. The clamping arms 6 are located in pairs on the upper part of the clamp body 100, and the re-inspection test plate 200 is installed between the clamping arms 6 and the clamp body 100. The clamp body 100 is provided with a mounting hole, and the guide rail 10 is installed in the mounting hole. The guide rail 10 and the clamp body 100 are fixedly connected by a locking screw. In this embodiment, the distance between the clamping arms 6 and the clamp body 100 is 14-28 mm. In other embodiments, the distance can also be adjusted as needed. The fixture body 100 is further provided with a backing plate groove 11 for installing a backing plate 300 . The backing plate 300 is fixedly connected to the re-test plate 200 . The backing plate groove 11 is located in the middle of the fixture body 100 .

[0033] like Figure 6-8 As shown, a mounting slot 7 is provided on the clamp arm 6, and the mounting slot 7 is a through slot. A support platform 8 is provided on the side of the mounting slot 7, and one end of the first slider 1 is placed on the support platform. The first slider 1 and the second slider 2 are both installed in the mounting slot 7, and the second slider 2 is located below the first slider 1; the first slider 1 is movably connected to the clamp body 100, and the second slider 2 cooperates with the first slider 1. Specifically, a pulling slider 9 is provided between the first slider 1 and the second slider 2, and the pulling slider 9 is fixedly connected to the first slider 1. In this embodiment, the two are connected by screws. In other embodiments, the two can also be an integrated structure. At the same time, the pulling slider 9 is slidably connected to the second slider 2, that is, the first slider 1 is slidably connected to the second slider 2, so that when the first slider 1 is loosened and tightened, the second slider 2 can move up and down in the vertical direction. As shown Figure 9 As shown, the holding slider 9 is installed in the second slider 2. A slot is provided on the upper end surface of the second slider 2, and the holding slider 9 is engaged in the slot. In this embodiment, the cross section of the holding slider 9 is T-shaped.

[0034] like Figure 3-5As shown, the slider cover 3 covers the first slider 1. The slider cover 3 is detachably fixedly connected to the fixture body 100. The loosening screw 5 and the clamping screw 4 are both provided on the slider cover 3. The clamping screw 4 is threadedly connected to the slider cover 3. The clamping screw 4 abuts against the first slider 1, and the loosening screw 5 is fixedly connected to the first slider 1. The horizontal movement of the second slider 2 is limited by the sidewalls of the mounting slot 7. Therefore, when the first slider 1 slides back and forth in the horizontal direction via the clamping screw 4 and the loosening screw 5, the second slider 2 can only move up and down within the mounting slot 7.

[0035] Furthermore, the slider cover 3 includes an end cap 30 and a cover plate 31. The end cap 30 is located on one side of the support platform, and the cover plate 31 is located above the first slider 1. The end cap 30 and the cover plate 31 are both detachably fixedly connected to the clamp body 100. The loosening screw 5 and the clamping screw 4 are both passed through the end cap 30. The clamping screw 4 is threadedly connected to the end cap 30, and a nut is installed between the loosening screw 5 and the end cap 30. A mounting hole is provided on the first slider 1, and the loosening screw 5 is fixedly installed in the mounting hole. The first slider 1 includes a wedge-shaped portion and a connecting portion. The wedge-shaped portion and the connecting portion are fixedly connected. The connecting portion is located on the support platform, and the wedge-shaped portion is located above the second slider 2. The upper end surface of the second slider 2 is an inclined surface, and the inclined surface cooperates with the lower end surface of the first slider 1.

[0036] When using this fixture, place the welding material re-test plate 200 between the fixture body 100 and the clamp arm 6, and the mounting plate 300 is located in the plate groove 11. When the clamping screw 4 is tightened, the clamping screw presses the first slider 1 inward, and the first slider 1 presses the second slider 2 downward, and the second slider 2 presses the re-test plate 200. Figure 4 When the retest plate 200 needs to be removed, the clamping screw 4 needs to be loosened, and the loosening screw 5 needs to be pulled out by tightening the nut, and the first slider 1 is also pulled outward. At this time, the horizontal movement of the second slider is limited by the side wall of the mounting groove. Therefore, when the first slider 1 slides horizontally toward the end cover by tightening and loosening the screws, the second slider 2 can only move upward in the mounting groove, as shown in FIG. Figure 5 When the second slider 2 is separated from the retest plate 200, the retest plate 200 can be taken out from the tooling.

[0037] The tooling of the utility model can be reused multiple times, is easy to operate, has no requirement on the length of the test plate, and tooling with different base materials can be used for different test plate materials.
