[0019] Please see Figures 1 to 3 A groove welding device includes a welding product 1, a first wedge block 2 and a second wedge block 10. The first wedge block 2 and the second wedge block 10 are sequentially installed inside the welding product 1. An mounting block 5 is fixedly connected to one side of the surface of the first wedge block 2. An mounting groove 9 is opened on the surface of the second wedge block 10 near the mounting block 5. One end of the mounting block 5 is installed inside the mounting groove 9. The inclined surfaces of the first wedge block 2 and the second wedge block 10 are set at 15 degrees. A first mounting hole 3 is opened on the top of the first wedge block 2.
[0020] The inner wall of the first mounting hole 3 is provided with a first threaded groove 4. The top of the second wedge block 10 is provided with a second mounting hole 8. The interior of the second mounting hole 8 is provided with a second threaded groove 7. A connecting component 6 is provided above the first wedge block 2 and the second wedge block 10. A handle 11 is provided above the connecting component 6. The end faces of the first wedge block 2 and the second wedge block 10 are both rounded to prevent scratching the product and to provide guidance when placed in the groove. The bottom end of the handle 11 is fixedly connected to the top of the locking block 603 for easy handling.
[0021] like Figure 3 As shown, the connecting assembly 6 includes a locking block 603. A first connecting hole 602 is formed through the surface of the locking block 603. A first screw 601 is disposed inside the first connecting hole 602. A second connecting hole 604 is formed on the surface of the locking block 603 away from the first connecting hole 602. A second screw 607 is disposed inside the second connecting hole 604. The first screw 601 and the second screw 607 facilitate the separation and connection of the first wedge block 2 and the second wedge block 10, making it more convenient to use. A first rotating member 606 is fixedly connected to the top of the first screw 601, and a second rotating member 605 is fixedly connected to the top of the second screw 607. Both the rotating component 606 and the second rotating component 605 are hexagonal in shape. The first rotating component 606 and the second rotating component 605 facilitate the rotation of the first screw 601 and the second screw 607, making the operation more convenient. The first screw 601 passes through the first connecting hole 602 and is installed inside the first threaded groove 4. The second screw 607 passes through the second connecting hole 604 and is installed inside the second threaded groove 7. The first screw 601 is threaded into the first threaded groove 4, and the second screw 607 is threaded into the second threaded groove 7, making it convenient to install the first screw 601 and the second screw 607 inside the first threaded groove 4 and the second threaded groove 7.
[0022] In use, this utility model employs a groove-following block for the groove welding fixture. The follower block is divided in half at a 15-degree angle. Mounting blocks 5 and 9 are respectively cut into the middle of the first wedge block 2 and the second wedge block 10 to restrict the lateral direction. When in use, the first wedge block 2 and the second wedge block 10 are staggered at 15 degrees for easy placement into the groove. Then, a locking block 603 is used to lock and flush the mounting groove 9 and mounting block 5. Secondly, the opening position of the follower needs to be appropriately increased according to the product's opening tolerance, making the top opening larger than the bottom, because the groove of the product will open after welding. The opening will be elastic and will shrink relative to the bottom; finally, after opening the first mounting hole 3 and the second mounting hole 8 in the middle of the first wedge block 2 and the second wedge block 10, a locking block 603 is added. After the first screw 601 and the second screw 607 are inserted into the groove in a staggered manner, the two sides are locked so that they are flush. Then, a handle 11 is locked on the locking block 603 for easy handling. The welding fixture will be stuck and difficult to remove, and removing it will scratch the product surface. After the two contour fixtures are welded, the screws are loosened so that the two contour fixtures are staggered at a 15-degree angle under the force, so that they can be easily removed without scratching the product.
