Embodiment 1

[0043] In a typical implementation of the present application, such as Figure 2-Figure 3As shown, the shear nail automatic welding unit with ceramic rings includes a stepped support plate, on which a shear nail material box 401, a ceramic ring material box 407, a nail removal mechanical arm 405, and a ceramic ring material box are arranged on the upper layer of the support plate. Turning mechanism 412 and cache positioning tooling 413, shear nails and ceramic ring clamping tooling 404 are provided at the end of the nail-taking mechanical arm;

[0044] The lower floor of the support plate is provided with a nail-feeding mechanical arm 408 and a welding torch lifting mechanism 410, and a welding torch 411 is connected on the described welding torch lifting mechanism 410, and the end of the described nail-feeding mechanical arm 408 is provided with shear nails and porcelain Ring combination fixture.

[0045] The shear nail automatic welding unit also includes a vision system, t...

Embodiment 2

[0055] This embodiment provides a shear nail automatic welding equipment with a ceramic ring, which is composed of a gantry 1, a guide rail 2, a welding workbench 3 and the welding unit 4 described in Embodiment 1; the guide rail 2 is arranged on the On the welding workbench 3, the gantry 1 can move along the guide rail 2, and the welding unit is fixed on the gantry.

[0056] As a further technical solution, a guide rail is also provided on one side of the gantry, and a slider is provided on the back of the support plate of the welding unit. The movement on the rack; and the guide rail is perpendicular to the installation direction of the above-mentioned guide rail 2, if the guide rail 2 is arranged along the x-axis direction, then the guide rail is arranged along the Y-axis direction. The moving direction of the gantry 1 and the moving direction of the welding unit are perpendicular to each other, so that the welding unit can move to any position of the welding table 3 .

Embodiment 3

[0058] This embodiment provides a method of using an automatic welding device for shear studs with a ceramic ring, as follows:

[0059] 1) Manually put the ceramic ring and the shear nail into the shear nail material box 401 and the ceramic ring material box 407 respectively.

[0060] 2) The moving slide mechanism 402 drives the vision system 403 to move from left to right to scan the positions of the workpieces in the shear nail material box 401 and the ceramic ring material box 407 below, and transmit the position information to the nail removal robot arm 405;

[0061] 3) The shear nails and ceramic ring clamping tool 404 on the nail picking robot arm 405 respectively pick up the shear nails and ceramic rings in the material box, and then the detection device on the mechanical arm 405 detects whether the direction of the ceramic ring is correct.

[0062] 4) The direction of the picked ceramic ring is correct, then the shear nail and the ceramic ring clamping tool 404 place t...

Description

technical field [0001] The invention relates to the field of shear nail welding equipment, in particular to an automatic shear nail welding unit, equipment and method with ceramic ring protection. Background technique [0002] There are many shear studs on the structural modules of the third-generation passive CAP1000 / CAP1400 nuclear power plants. Their main function is to combine the steel plate and concrete into a whole, so that the two can jointly resist the external force. During the welding process of the shear studs on the structural modules, ceramic rings are required for welding protection to achieve the following purposes: [0003] (1) Concentrate the arc heat on the welding area during welding; [0004] (2) Prevent air from entering the welding area to reduce the degree of oxidation of molten metal; [0005] (3) Prevent the loss of molten metal and help the formation of welds in various spatial positions. [0006] At present, the shear stud welding of nuclear po...
