Technical Field

[0001] The utility model relates to the field of welding fixtures, in particular to a welding fixture for a bus duct shell. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system.

[0003] In the process of processing the bus duct shell, it is necessary to first perform processes such as cutting, bending and welding. In the welding process of the bus duct shell, it is indeed necessary to accurately align the two shells and implement effective limiters to ensure the welding quality and avoid structural defects caused by offset. In the welding of the two shells, it is inevitable that some parts will need to be angled to ensure that the angle at the corner is accurate, which can effectively guarantee the quality of the bus duct shell welding and ensure that its structural strength and electrical performance meet the use requirements.

[0004] In summary, there is an urgent need for a bus duct shell welding fixture with adjustable angle to solve the above problems. Utility Model Content

[0010] Furthermore, the angular distance between each fixing groove is set within 5 degrees.

[0011] Furthermore, one end of the contact plate is configured to be inclined.

[0012] The beneficial effects of the utility model are as follows: by rotating the two rotating rods and driving the movable plate to move forward and backward, shells of different thicknesses can be fixed and limited to ensure welding quality and avoid structural defects caused by offset. At the same time, rotating the angle of the rotating frame can change the welding angle of the two shells, and the two sliding frames are clamped in the fixed groove to prevent the rotating frame from moving at will, thereby ensuring that the angle at the corner is accurate.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Embodiment: A busbar housing welding fixture, such as Figures 1-4The cam 32 is fixed to the left and right sides of the support plate 1, and the cam 32 is fixed to the right and left sides of the support plate 1. The cam 32 is fixed to the left and right sides of the support plate 1, and the cam 32 is fixed to the right and left sides of the support plate 1. The cam 32 is fixed to the right and left sides of the support plate 1, and the cam 32 is fixed to the left and right sides of the support plate 1. The cam 32 is fixed to the right and left sides of the support plate 1, and the cam 32 is fixed to the left and right sides of the support plate 1. The cam 32 is fixed to the right and left sides of the support plate 1, and the cam 32 is fixed to the left and right sides of the support plate 1. The cam 32 is fixed to the right and left sides of the support plate 1, and the cam 32 is fixed to the left and right sides of the support plate 1. The cam 32 is fixed to the right and left sides of the support plate 1, and the cam 32 is fixed to the left and right sides of the support plate

[0021] like Figure 4-Figure 5 As shown, it also includes a fixed plate frame 8, a movable frame 9, a spring 10 and a contact plate 11. The bottom of the front side of the support plate 1 is connected to the fixed plate frame 8 by screws. The movable frame 9 is slidably arranged on the fixed plate frame 8. The front side of the movable frame 9 is symmetrically provided with a spring 10, and one end of the spring 10 is connected to the fixed plate frame 8, and the other end is connected to the movable frame 9. The rear side of the movable frame 9 is connected to the contact plate 11, and one end of the contact plate 11 is set to an inclined shape to facilitate pushing it onto the supporting table.

[0022] like Figure 3 As shown, a rubber plate 4 is also included. Both movable plates 32 are connected with a rubber plate 4 to prevent the housing from being scratched by friction during the fixing process.

[0023] like Figure 3 As shown, an anti-slip cover 12 is also included. Both sliding frames 7 are covered with the anti-slip cover 12 to prevent the workers' hands from sweating, which may cause the sliding frames 7 to be detached and difficult to slide out.

[0024] When it is necessary to process and weld the bus duct shell, first complete the previous cutting and bending processes, place the two shells to be welded on a suitable supporting table, and then push the clamp to the edge of the supporting table, whereupon the support plate 1 and the contact plate 11 will contact the supporting table. At the same time, the movable frame 9 will move downward because the thickness of the supporting table is greater than the thickness between the support plate 1 and the contact plate 11, and the spring 10 will be stretched, and the fixed plate frame 8 plays a guiding role, so that the clamp can be fixed on the supporting table. When clamping is not needed, the fixed plate frame 8 can be removed. After fixing the clamp, the staff will fix the two shells, and then the staff will rotate the two rotating rods 33, and the movable plate 32 will move forward. After moving to the appropriate distance, the staff will stop rotating the two rotating rods 33, and then place the two shells to be welded on the rotating frame 3, and then the staff will reverse the two rotating rods 33, and the movable plate 32 will reset backward. The sliding bracket 32 ​​is then moved back to the original position to be engaged with the fixing groove 31, thereby preventing the rotating bracket 3 from rotating at will. Repeating the above-mentioned action can fix the shell and adjust the angle of the welding shell.

[0025] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art may make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention.
