During production, it is necessary to weld the tank body and the end covers. Currently, for the welding of this type of workpiece, the common practice is to first manually position and fix the tank body and the end covers by spot welding, then move the tank body to a tooling, and then weld the circumferential seam between the tank body and the end covers. This method requires two processes and also requires handling, thus affecting the welding efficiency. Summary of the Utility Model

[0011] Advantages of the present utility model:

[0012] For the welding device for tank-type workpieces of the present utility model, through the cooperation of the end cover support and positioning mechanism and the tank body support and positioning mechanism, the cumbersome steps in the traditional process of manually spot-welding first and then transporting to the fixture for circumferential welding are reduced. The present utility model realizes the one-time positioning of the tank body and the end cover, avoiding the conversion and transportation between processes, thereby significantly improving the welding efficiency. In the traditional welding process, workers need to manually perform spot-welding positioning and then transport to the fixture for circumferential welding, which not only has a high labor intensity but also has certain safety hazards. The present utility model completes these steps through an automated method, effectively reducing the labor intensity of workers and improving the safety of the workplace.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0020] As Figure 1 - Figure 4As shown in the figure, the welding device for canned workpieces of the present utility model mainly includes a base 1, an end cover support and positioning mechanism 2, a tank body support and positioning mechanism 3, and a welding mechanism 4.

[0021] The base 1 is the foundation of the entire device and is used to support and position other parts. The base 1 is stably placed on the working ground to ensure the stability of the entire welding process.

[0022] Figure 3 As shown in the figure, the end cover support and positioning mechanism 2 is arranged on the base 1, and its main function is to support an end cover 7 up and down along the axial direction. Specifically, the end cover support and positioning mechanism 2 includes an annular support seat 21, and the annular support seat 21 is fixed on the base 1 for placing the end cover 7 to be welded. The end cover 7 can be stably placed on the annular support seat 21 to ensure accurate positioning during welding.

[0023] Figure 4 As shown in the figure, the tank body support and positioning mechanism 3 is arranged on one side of the base 1 and is used to support and position the tank body 6. The tank body support and positioning mechanism 3 includes a lifting assembly 31 and a tank body support assembly 32. The lifting assembly 31 is arranged on one side of the base 1, and the tank body support assembly 32 is connected to the lifting assembly 31. Specifically, the lifting assembly 31 includes a support frame 311 and a lifting module 312. The support frame 311 is stably arranged on one side of the base 1, and the lifting module 312 is installed on the support frame 311. The mounting ring 321 of the tank body support assembly 32 is connected to the lifting module 312, thereby realizing the lifting function of the tank body support assembly 32.

[0024] The specific structure of the tank body support assembly 32 is as Figure 4 shown, and it includes a mounting ring 321 and a plurality of support columns 322. The mounting ring 321 is connected to the lifting module 312, and the plurality of support columns 322 are circumferentially arranged on the mounting ring 321. Each support column 322 is arranged vertically and encloses a positioning part, and the tank body 6 is arranged in this positioning part. The support columns 322 are used to abut against the outer wall of the tank body 6 to realize the positioning of the tank body 6.

[0025] In some embodiments, a plurality of rollers 323 are further arranged on the support columns 322. These rollers 323 are arranged along the axial direction of the support columns 322 and are used to abut against the outer wall of the tank body 6, thereby reducing the resistance of the support columns to move up and down.

[0026] During the welding process, the lifting assembly 31 can drive the tank body support assembly 32 to rise or fall. After the tank body 6 and the end cover 7 at one end are placed in the appropriate positions, the welding mechanism can first perform spot welding for positioning, and then circumferential welding can be carried out. After the end cover 7 at this end is welded, the lifting assembly 31 can drive the tank body support assembly 32 to rise. At this time, the other end cover 7 can be placed in place to support the end cover 7 at the other end, so as to realize the positioning and support of the other end cover 7.

[0027] The welding mechanism 4 is used to perform spot welding and circumferential welding on the tank body 6 and the end cover 7 in sequence. The welding mechanism 4 can include necessary welding equipment such as welding torches and welding power sources to realize an automated welding process. After the tank body 6 and the end cover 7 are correctly positioned and supported, the welding mechanism 4 can perform spot welding and circumferential welding according to a preset welding procedure, thus completing the welding work of the tank body 6 and the end cover 7.

[0028] In addition, the base 1 can also be connected to a rotating module 5. The rotating module 5 is used to drive the base 1 to rotate, so as to adjust the welding position of the tank body 6 to meet different welding requirements and improve the welding efficiency.

[0029] Generally speaking, the welding device for tank-shaped workpieces of the present utility model realizes the simultaneous positioning and support of the tank body and the end cover, as well as an automated welding process through a reasonable structural design, thus greatly improving the welding efficiency and welding quality.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model belong to the scope of protection of the present utility model.
