[0002] Currently, most integrated stove air duct components are manufactured using contouring fixtures to first limit the position of the parts, and then they are manually welded. However, manual welding is inefficient and the welding is not uniform enough. After welding, grinding is required, so improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies, such as low efficiency and low precision in manual welding, by providing a new welding fixture for integrated stove air ducts.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

The front end and rear end of the inner support assembly are respectively provided with front plate clamping assemblies and rear plate clamping assemblies for squeezing the front plate and rear plate of the air duct.

[0007] The side plate clamping assembly, front plate clamping assembly, and rear plate clamping assembly can be used to fix and weld the air duct side plate, air duct front plate, and air duct rear plate. The air duct formed after welding is then fitted onto the inner support assembly.

[0008] In this solution, the left side plate, right side plate, front plate, and rear plate of the air duct are pressed onto the inner support assembly by the side plate pressing assembly, the front plate pressing assembly, and the rear plate pressing assembly. Then, laser welding can be used to weld the joints of the plates, thereby improving work efficiency and processing accuracy.

[0009] Preferably, in the welding fixture for the integrated stove air duct described above, the base of the fixture has an installation space, and the inner support component is installed in the installation space.

[0010] Preferably, the welding fixture for the integrated stove air duct described above includes an upper base and a lower base, with an movable space formed between the upper base and the lower base. A first track is provided within the movable space, and the inner support assembly is installed on the first track.

[0011] Preferably, in the welding fixture for the integrated stove air duct described above, a first pushing cylinder is provided in the active space near the first track, and the driving end of the first pushing cylinder cooperates with the lower end of the inner support assembly.

[0012] Preferably, in the welding fixture for the integrated stove air duct described above, the side plate clamping assembly includes a first fixing seat, on which a plurality of first clamping cylinders are longitudinally distributed, and the first fixing seat is mirror-image disposed on both sides of the inner support assembly.

[0013] As a preferred embodiment, the welding fixture for the integrated stove air duct described above includes a second fixing seat in both the front plate pressing assembly and the rear plate pressing assembly, and the second fixing seat has a plurality of second pressing cylinders distributed longitudinally.

[0014] Preferably, in the welding fixture for the integrated stove air duct described above, the upper base is provided with a second track near the front plate pressing assembly and the rear plate pressing assembly, and the front plate pressing assembly and the rear plate pressing assembly are both arranged on the second track.

[0015] Preferably, the welding fixture for the integrated stove air duct described above is further provided with a second pushing cylinder near the second track, and the driving end of the second pushing cylinder cooperates with the lower end of the front plate pressing assembly and the rear plate pressing assembly.

[0016] The present invention has the following advantages through the above structural design:

[0017] The left, right, front, and rear plates of the air duct are pressed onto the inner support assembly by the side plate pressing assembly, the front plate pressing assembly, and the rear plate pressing assembly. Then, laser welding can be performed on the joints of the plates. The above structure can effectively improve the accuracy of welding to prevent secondary grinding after welding, and can also effectively improve the processing efficiency.

[0026] Example 1

[0027] like Figures 1-6 As shown, a welding fixture for an integrated stove air duct includes a welding fixture body 1, the welding fixture body 1 includes a fixture base 11, and the fixture base 11 is provided with an inner support component 111 for supporting the air duct.

[0028] Both sides of the inner support assembly 111 are provided with a plurality of side plate clamping assemblies 2 for squeezing the side plates of the air duct. The front end and rear end of the inner support assembly 111 are respectively provided with a front plate clamping assembly 3 and a rear plate clamping assembly 4 for squeezing the front plate and the rear plate of the air duct.

[0029] The side plate clamping assembly 2, the front plate clamping assembly 3, and the rear plate clamping assembly 4 can be used to fix and weld the air duct side plate, the air duct front plate, and the air duct rear plate. The air duct formed after welding is then fitted onto the inner support assembly 111.

[0030] Specifically, the inner support assembly 111, side plate clamping assembly 2, front plate clamping assembly 3, and rear plate clamping assembly 4 in this application can be replaced accordingly depending on the different production shapes.

After welding is completed, the first push cylinder 52 pushes the inner support assembly 111 inward to facilitate the loosening of the front plate and rear plate of the air duct.

[0037] Preferably, each of the side plate clamping assemblies 2 includes a first fixing seat 21, on which a plurality of first clamping cylinders 211 are longitudinally distributed, and the first fixing seats 21 are mirror images of each other on both sides of the inner support assembly 111.

[0038] Specifically, the first clamping cylinder 211, which is set by mirroring, can clamp the left side plate and the right side plate of the air duct onto the inner support assembly 111 respectively.

[0039] Preferably, both the front plate clamping assembly 3 and the rear plate clamping assembly 4 include a second fixing seat 6, and the second fixing seat 6 has a plurality of second clamping cylinders 61 arranged longitudinally.

[0043] Specifically, with the above-mentioned structure, after the air duct welding is completed, the second push cylinder 7 can push the front plate clamping assembly 3 and the rear plate clamping assembly 4 away from the inner support assembly 111, thereby facilitating the disassembly of the air duct after welding.
