Example

[0034] Based on the second embodiment, the moving mechanism 9 mentioned in the second embodiment is described as follows:

[0035] The moving mechanism 9 includes a second servo motor 901, a rotating shaft 902, a first bevel gear 903, a second bevel gear 904, a bidirectional screw 905 and a U-shaped slide 906. The second servo motor 901 is fixedly installed on the other side of the workbench 1, and the output shaft of the second servo motor 901 is fixedly connected to the rotating shaft 902 through a coupling. First bevel gears 903 are arranged at both ends of the rotating shaft 902. The first bevel gear 903 is meshed with the second bevel gear 904 arranged at one end of the bidirectional screw 905. U-shaped slides 906 are symmetrically arranged at both ends of the bidirectional screw 905. Both sides of the bottom end of the U-shaped slide 906 are threadedly connected to the bidirectional screw 905, and the top of the U-shaped slide 906 is arranged with a first telescopic rod 801.

[0036] An L-shaped slide plate 10 is fixedly installed at the center of the U-shaped slide plate 906, and a clamping block 11 is provided at the top of the L-shaped slide plate 10. The clamping block 11 is used to clamp and fix the heat shield body 14 outside the catalyst assembly body 4.

[0038] In this embodiment, by providing a moving mechanism 9, the function of moving the welding mechanism 8 left and right along the first slide groove 12 is realized, so that during the rotation of the catalyst assembly body 4 and the heat shield body 14, the welding mechanism 8 and the clamping block 11 can be ensured to be away from the heat shield body 14 without affecting the rotation and turning over thereof.

The support seat 3 is moved along the slide bar on one side of the workbench to the other end of the catalyst assembly body 4, so that the T-shaped positioning column 603 on the inner side of the top of the mobile support seat 3 is adapted to the other end of the catalyst assembly body 4, ensuring the stability between the two ends of the catalyst assembly body 4 and the T-shaped positioning columns 603 on both sides, so that the rotation of the positioning component 6 drives the catalyst assembly body 4 to rotate, and then the second servo motor 901 is driven to make the U-shaped slides 906 at both ends of the bidirectional screw 905 approach each other, so that the clamping The block 11 clamps and fixes the heat insulation cover body 14, and then the heat insulation cover body 14 is welded by the welding gun 806 driven by the cooperation of the first telescopic rod 801 and the second telescopic rod 803. The welding gun 806 welds the catalyst welding ring and the heat insulation welding ring on the heat insulation cover body 14 to achieve welding. After the welding of both sides of the heat insulation cover body 14 is completed, the welding gun 806 is moved outward by the drive of the second servo motor 901. At the same time, the clamping block 11 no longer clamps the heat insulation cover body 14, and then the catalyst assembly body 4 and the heat insulation cover body 14 are driven by the first servo motor 701 to rotate, and the upper and lower sides are rotated to weld the two sides, without manual flipping welding, thereby improving work efficiency.
