[0103] Example 7

[0104] like Figure 1 , 2 As shown in Figure 3, this embodiment provides a welding device for a double-layer thermos cup. In addition to the technical solution of the embodiment, it also has the following technical features.

[0105] The mounting plate 130 is provided with an expansion module 700 , and the expansion module 700 is used to expand the inner wall opening outward to fit with the outer wall.

[0106] In the present technical solution, a flaring module 700 is provided on the mounting plate 130, and the flaring module 700, the cup body positioning portion 200 and the outer cup bottom welding seat 400 are arranged in sequence from left to right, and the flaring module 700 is composed of a second support plate 710, a flaring cylinder 720, a connecting shaft 730 and a conical block 731. The outer diameter of the conical block 731 gradually decreases from left to right, and the outer diameter at the rightmost end of the conical block 731 is smaller than the inner diameter of the outer wall cup mouth before flaring, and the outer diameter at the leftmost end of the conical block 731 is larger than the inner diameter of the inner wall cup mouth before flaring, and The flaring cylinder 720 places the output shaft in the through hole, and the connecting shaft 730 is connected to the output shaft of the flaring cylinder 720. The conical block 731 is rotatably connected to the connecting shaft 730. The conical block 731 can be moved left and right by the movement of the flaring cylinder 720. The rotatable connection between the conical block 731 and the connecting shaft 730 allows the conical block 731 to rotate along with the rotation of the cup body when the outer cup bottom is welded to the cup body, thereby improving the stability during the welding process.

[0107] In this technical solution, when the outer cup bottom and the cup body are welded, the expansion cylinder 720 moves the conical block 731 to the right into the inner cavity of the inner wall, and as the cylinder extends, the conical block 731 expands the peripheral wall of the inner wall cup mouth outward until it fits with the inner wall of the outer wall cup mouth. When the cup mouth of the inner wall fits with the cup mouth of the outer wall, the welding part 500 is used to weld the fitting part to make the structure of the cup body more stable.

[0108] During actual production, the cup body positioning seat is rotated to set the positioning hole 241 of the cup body positioning part 200 coaxially with the turntable of the inner cup bottom welding seat 300, and then the worker places the inner wall in the positioning hole 241, and places the inner cup bottom in the inner cup bottom positioning groove 321 of the inner cup bottom welding seat 300, and the inner wall squeezes the spring plunger 242 in the positioning hole 241, and uses the spring plunger 242 to fix it. After the fixing is completed, the moving module 230 works to move the positioning block 240 downward, and at the same time, the pressing module 600 operates to make the inner wall and the inner cup bottom in close contact, and then the inner welding part 510 welds the inner wall and the inner cup bottom through the groove of the first positioning baffle 330, and the first motor 310 drives the semi-finished product on the turntable to rotate. When the welding of the inner cup bottom and the outer wall is completed, the pressing module 600 is recovered, the moving module 230 moves the positioning block 240 upward, and the rotating motor 21 The positioning hole 241 is coaxially arranged with the second rotating disk 420 of the outer cup bottom welding seat 400, and the expanding module 700 is operated to extend the conical block 731 into the inner cavity. At this time, the worker sets the outer wall on the inner wall, fixes the outer cup bottom through the suction cup 421 and the second positioning baffle 430, and the moving module 230 moves the positioning block 240 toward the outer cup bottom welding seat 400 to contact the outer wall with the outer cup bottom. The expanding module 700 expands the inner wall opening to fit the inner wall opening with the outer wall opening, and then the second motor 410 rotates, and the outer welding part 520 uses the moving motor 522 to move the outer welding gun 523 to the outer cup bottom welding seat 400 to weld the outer cup bottom and the outer wall. After the welding of the outer cup bottom and the outer wall is completed, the moving motor 522 rotates again to move the outer welding gun 523 to the fitting position of the outer wall opening and the inner wall opening to weld the fitting position, and finally the manufacture of the workpiece is completed.
