[0040] Base 2;

[0041] A mounting frame assembly, which is mounted on the base 2;

[0042] A rotating assembly is installed in the mounting frame assembly, and the rotating assembly is located at the outer end of the mounting frame and is connected to a cylinder assembly;

[0043] A fixed tooling assembly, which is mounted on the cylinder assembly;

[0044] A gas protection device is installed in the mounting frame assembly.

[0045] Furthermore, the mounting frame assembly includes a front cover 12, a rear cover 11 and a top cover 1, the rear cover 11 is vertically fixed at one end of the base 2, the front cover 12 is vertically fixed on the base 2, the top cover 1 is arranged on the front cover 12 and the rear cover 11, the front cover 12 is provided with a first clearance hole 121 for the rotating assembly to pass through, and the rear cover 11 is provided with a second clearance hole 112.

[0046] Furthermore, a fixing plate 101 is fixed to the top of the top cover 1, and the rotating assembly is mounted on the fixing plate 101. The rotating assembly includes:

[0047] The rotating motor 6 is located at the first clearance hole 121, and both ends of the rotating motor 6 have a rotating shaft 61;

[0048] A positioning buckle 1011, which is fixed on the fixing plate 101 and has a first bearing 1012 in the middle for the rotating shaft 61 to pass through;

[0049] The positioning buckles 1011 are two in number, and the rotating shaft 61 at one end of the rotating motor 6 passes through the second clearance opening and is connected to the positioning arm 41 .

[0050] Furthermore, a positioning hole 111 is formed on the lower side of the rear cover 11 , and a positioning post 411 is formed on the positioning arm 41 and can be inserted into the positioning hole 111 for positioning.

[0051] When the rotating assembly rotates to the welding position, the positioning column 411 on the positioning arm 41 is inserted into the positioning hole 111 to position the bead for subsequent welding work.

[0052] Furthermore, the rotating shaft 61 at the other end of the rotating motor 6 is fixedly connected to the cylinder assembly in a clamping manner. This structure allows the cylinder assembly to rotate along with the rotating shaft 61 when the rotating motor 6 drives it to rotate, thereby driving the fixed tooling assembly to rotate to realize the rotation of the welding position and achieve multilateral welding.

[0053] The cylinder assembly comprises:

[0054] The tooling support plate 5, whose rear end is fixedly connected to the rotating shaft 61, is provided with a mounting groove 501, and a first displacement hole and a second displacement hole 503502 are provided on the tooling support plate 5 at the front end of the mounting groove 501;

[0055] The propulsion cylinder 53 is fixedly installed in the installation groove 501. The telescopic end of the propulsion cylinder 53 is connected to a U-shaped connecting slider 54. The connecting slider 54 is provided with a slider connecting shaft 541 at the positions corresponding to the first displacement hole and the second displacement hole 503502;

[0056] Ball bearings 542 are provided at both ends of the slider connecting shaft 541 at the first displacement hole, a slide plate 51 is provided at the end of the connecting slider 54, a limiting groove is provided on the slide plate 51, and a limiting plate 52 corresponding to the limiting groove is provided at the outermost end of the tooling support plate 5.

[0062] Furthermore, the distance between the two wedge blocks 32 on the same side is smaller than the diameter of the ball bearing 542 .

[0063] The connecting slide block 54 is pushed by the thrust cylinder 53, and the ball bearing 542 on the first displacement hole of the connecting slide block 54 moves forward and enters between the wedge blocks 32, pushing the two wedge blocks 32 to both sides, so that the inner side plate 31 of the tooling can be close to the water tank to be welded. The slide plate 51 moves forward until the limit plate 52 is embedded in the limit groove, which is the extreme position, and the water tank to be welded can be completely fixed. Because the rear end of the inner side plate 31 of the tooling is fixed to the tooling support plate 5 by the plate shaft 55, the inner side plate 31 of the tooling can rotate at a small angle relative to the plate shaft 55.

[0064] Furthermore, one side of the inner plate 31 of the tooling is a welding edge, and an air outlet 301 is provided at the welding edge. The edge of the welding edge is a welding seam 302 for gas to flow out. The gas protection device includes a mounting plate 7, a gas conveyor 71 and a gas pipe. The mounting plate 7 is fixed in the mounting frame assembly. The gas conveyor 71 is fixed on the mounting plate 7. One end of the gas pipe is connected to the gas conveyor 71. A gas diverter 72 is provided on the tooling support plate 5. The other end of the gas pipe is connected to the gas diverter 72, and the gas diverter 72 is connected to a plurality of diverter pipes connected to the air outlet 301. The welding tooling is provided with gas protection, and the gas conveyor 71 is connected to an external gas supply device to deliver gas to each air outlet 301 of the diverter pipe in the diverter channel. The welding work is coordinated with the welding seam 302, which can ensure that the box body is welded on one side and both sides are transparent, and there is no yellow spot stain inside after welding, so that the weld is white and flawless, beautiful, etc., which meets the standard requirements.

[0065] Principle: This equipment adopts a horizontal welding structure. First, place the water tank to be welded on the fixed tooling assembly. Drive the connecting slider 54 forward by pushing the cylinder 53, so that the ball bearing 542 moves forward to push open the wedge block 32 of the inner plate 31 of the tooling, and open the inner plate 31 of the tooling to clamp the box body. Drive the rotating shaft 61 through the rotating motor 6 to drive the tooling to rotate and position 0 to 360°, so that the product can be clamped and multi-sided combined welding can be completed at one time. After welding, the overall weld of the water tank is uniform and firm, and the box body is not deformed after welding, ensuring that the accuracy of the overall size of the water tank meets the requirements of the drawing.

[0066] The equipment uses a PLC programmable controller, which features quick operation, stable clamping, and precise rotation and positioning, thus greatly improving the welding quality of the product, making the weld balanced, firm, and beautiful, while also increasing production capacity and reducing production energy consumption.

[0067] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.
