[0029] The following is for reference. Figure 1 and Figure 2 Describes the welding fixture for the water receiving rack according to an embodiment of the present utility model.

[0030] like Figure 1 and Figure 2 As shown, the water receiving rack welding fixture according to an embodiment of the present utility model includes a stand 100, two welding seats 200 and two clamping devices 400.

[0031] A crossbeam 110 is provided on the support frame 100; two welding seats 200 are located on the left and right sides of the crossbeam 110 respectively, and the welding seats 200 have alignment surfaces 230. The box-shaped workpiece 500 can be fitted onto the welding seats 200. The alignment surfaces of the welding seats 200 abut against the left and right sides of the upper inner wall of the workpiece 500. Protective air holes 240 are distributed on the alignment surfaces 230; two clamping devices 400 are located on the crossbeam 110, and the clamping devices 400 are located on the left and right sides of the welding seats 200 respectively. The clamping devices 400 are provided with clamping heads 410, and the clamping heads 410 can abut against the left and right sides of the outer outer wall of the workpiece 500.

[0032] For example, such as Figure 1 and Figure 2 As shown, a crossbeam 110 is provided on the upright frame 100 to keep the fixture relatively fixed during operation. Two welding seats 200 are located on the left and right sides of the crossbeam 110, respectively, meaning the welding seats 200 are relatively fixed on the crossbeam 110. (Refer to...) Figure 2 , Figure 3 The welding base 200 has an alignment surface 230. A box-shaped workpiece 500 can be fitted onto the welding base 200. The alignment surface of the welding base 200 abuts against the left and right sides of the upper inner wall of the workpiece 500, that is, the alignment surface 230 is in close contact with the inner wall of the workpiece 500 to fix the workpiece 500. Protective vent holes 240 are distributed on the alignment surface 230 for spraying protective gas, such as argon. Two clamping devices 400 are located on the crossbeam 110, and the clamping devices 400 are located on the left and right sides of the welding base 200, respectively. The clamping device 400 is provided with clamping heads 410, which can press against the left and right sides of the outer wall of the workpiece 500. This is equivalent to the welding seats 200 on both sides of the fixture of this utility model pressing against the inner sides of the workpiece 500, while the clamping heads 410 on both sides press against the outer sides of the workpiece 500. In this way, the clamping device 400 and the welding seats 200 cooperate to fix the workpiece 500 to be welded.

[0033] In normal times, refer to Figure 3The fixture of this utility model does not have a workpiece 500. In actual operation, taking a square box-shaped workpiece 500 as an example, the workpiece 500 is first placed on the welding seat 200, with the end of the welding seat 200 abutting against the bottom wall 520 of the workpiece 500, and the alignment surface 230 on the welding seat 200 pressed against the inner wall of the workpiece 500. Then, the clamping head 410 of the clamping device 400 abuts against the outer wall of the workpiece 500, ensuring that the workpiece 500 is fixed in place. Then, the protective gas is ejected from the protective gas hole 240 on the welding seat 200, and in conjunction with the welding torch, welding can be performed on the corner line 530 of the workpiece 500 from the outside.

[0034] The above operation is simple and can quickly fix the workpiece 500, facilitating welding with the welding gun. Simultaneously, the welding seat 200 not only fixes the workpiece 500 but also sprays shielding gas for better welding results. After welding is completed, the clamping head 410 releases, allowing the workpiece 500 to be easily removed, resulting in high overall work efficiency.

[0035] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 , Figure 3 The support frame 100 also includes a base frame 120, on which columns 130 are mounted, and a crossbeam 110 is connected to the upper side of the column 130. The base frame 120 serves as the supporting structure for the support frame 100, while the column 130 connects to the crossbeam 110, ensuring that the crossbeam 110 is at a suitable height.

[0036] In some embodiments of this utility model, the crossbeam 110 and the column 130 are detachably connected, which makes it easy for the crossbeam 110, together with the welding seat 200 and the clamping device 400 on the crossbeam 110, to be replaced according to the size and shape of the workpiece 500.

[0037] In some embodiments of this utility model, an elongated mounting groove 111 is provided on the lower side of the crossbeam 110. The elongated mounting groove 111 is connected to the upper side of the column 130 by screws. This ensures that the column 130 can fix crossbeams 110 of different lengths to match different workpieces 500.

[0038] In some embodiments of this utility model, a base beam 140 is provided on the base frame 120, and the base beam 140 also has an elongated mounting groove 111. The elongated mounting groove 111 on the base beam 140 can also be connected to the upper side of the column 130 by screws.

[0039] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4The welding base 200 includes a rear fixed portion 210 and a front extended portion 220. The fixed portion 210 is connected to the crossbeam 110. The extended portion 220 extends forward, making it easier for the workpiece 500 to be fitted onto the extended portion 220 of the welding base 200.

[0040] In some embodiments of this utility model, a gas connection pipe 300 is connected to the rear side of the fixing part 210. The gas connection pipe 300 can be connected to an external gas source and is used to introduce protective gas. The connection position of the gas connection pipe 300 to the fixing part 210 can prevent the gas connection pipe 300 from affecting the welding work.

[0041] In some embodiments of this utility model, reference is made to Figure 3 The gas connection pipe 300 includes a main air pipe 310 and a branch air pipe 320. The main air pipe 310 is connected to the fixed part through the branch air pipe 320, and the protective air hole is connected to the branch air pipe. In this way, only one gas source needs to be connected to the gas connection pipe 300 to supply air to the protective air holes 240 on both sides.

[0042] In some embodiments of this utility model, the alignment surface 230 is a right-angled surface, which includes a horizontal surface 231 and a vertical surface 232. The horizontal surface 231 and the vertical surface 232 are connected by a corner line 233, and the protective air holes 240 are distributed on the corner line 233, which better matches the square water receiving rack structure.

[0043] In some embodiments of this utility model, the alignment surface 230 is a right-angled surface, the alignment surface 230 is an arc-shaped surface, and the protective air holes 240 are distributed on the arc-shaped surface, which can better match the water receiving rack structure with rounded corners.

[0044] In some embodiments of this utility model, reference is made to Figure 5 , Figure 6 The clamping device 400 includes a fixed cylinder 420, and a clamping head 410 is inserted into the fixed cylinder 420.

In this way, the relative position between the adjustable chuck 411 and the clamping head 410 can be adjusted so that the clamping head 410 can match workpieces of different widths.

[0045] In some embodiments of this utility model, a swing arm 430 is provided on the fixed cylinder 420. The two ends of the swing arm 430 are an operating end 431 and a linkage end 432, respectively. A swing arm main shaft 433 is provided between the operating end 431 and the linkage end 432. The swing arm 430 is connected to the fixed cylinder 420 through the swing arm main shaft 433. A connecting rod 440 is connected between the linkage end 432 and the clamping head 410. The two ends of the connecting rod 440 are connected to the linkage end 432 and the clamping head 410 through rotating shafts, respectively. The swing arm 430 can rotate and swing along the swing arm main shaft 433. The linkage end 432 on the swing arm main shaft 433 drives the connecting rod 440, thereby pulling the clamping head 410 to extend and retract. In this way, the extension and retraction of the clamping head 410 can be controlled by operating the swing arm 430.

[0046] In some embodiments of this utility model, a return spring is provided between the fixed cylinder 420 and the clamping head 410. The return spring applies a pushing force to the clamping head 410 to ensure that the clamping head 410 can hold the workpiece.

[0047] In some embodiments of this utility model, the clamping device 400 is provided with a clamping device fixing plate 450, and the clamping device fixing plate 450 is provided with screw holes for screws to be installed. The clamping device 400 is connected to the crossbeam 110 through the clamping device fixing plate 450.
