Description

Technical Field

[0001] This utility model belongs to the field of busbar trunking production technology, specifically relating to a limiting device for busbar trunking production. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns, used to distribute a large amount of power to various components of a distributed system. With the development of modern buildings, more and more buildings have irregular installation surfaces. Busbar trunking needs to be installed on such irregular installation surfaces. Therefore, busbar trunking will have different specifications of bends, and these bends need to be welded securely.

[0003] Currently, when welding busbar trunking, a simple assembly method is generally used, where the interfaces to be welded are aligned and then welded. Because the busbar trunking at a certain angle lacks restraint, it is easy to cause incomplete welds at the joints, reducing the strength of the weld at the joint between the two busbar trunking sections.

[0004] Therefore, a limiting device for busbar production is proposed. Summary of the Invention

[0005] This utility model provides a limiting device for busbar production, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a limiting device for busbar trunking production, including a busbar trunking processing platform; a fixing plate fixed to the top of the busbar trunking processing platform; a stepper motor fixed to the top of the fixing plate; a rotating plate fixed to the output end of the stepper motor; an arcuate through slot opened on the top of the busbar trunking processing platform; an arcuate platform located on the outer wall of the rotating plate near the inner side of the arcuate through slot; a ball screw 1 rotating inside the arcuate platform; a limiting plate 1 fixed to the output end of the ball screw 1 by screws; a ball screw 2 rotating inside the busbar trunking processing platform; a limiting plate 2 fixed to the output end of the ball screw 2 by screws; side plates fixed to one side of the limiting plate 1 and the limiting plate 2 respectively; an electric push rod fixed to the outer wall of one side of the side plate; a push plate fixed to the output end of the electric push rod; and handwheels fixed to one end of the ball screw 1 and the ball screw 2 respectively.

[0007] Furthermore, the arc stage and the arc through groove are slidably connected, and the center of the arc stage, the center of the arc through groove and the axis of the stepper motor output end are on the same vertical axis.

[0008] By adopting the above technical solution, the stability of the circular arc platform during axial circumferential motion is ensured, providing better support for the busbar groove on the circular arc platform.

[0009] Furthermore, a recess is provided on the top of the busbar processing platform near the outer side of ball screw one and ball screw two.

[0010] By adopting the above technical solution, the smooth rotation of ball screw one and ball screw two is guaranteed.

[0011] Furthermore, the second limiting plate and the busbar processing platform are slidably connected, and the first limiting plate and the arc table are slidably connected;

[0012] By adopting the above technical solution, the stability of the first limiting plate moving above the arc table is guaranteed, and the stability of the second limiting plate moving above the busbar processing platform is guaranteed.

[0013] Furthermore, the fixed plate and the rotating plate are perpendicular to each other with the side plate;

[0014] By adopting the above technical solution, it is ensured that the subsequent push plate can drive the busbar trunking to move.

[0015] Furthermore, matching grooves are respectively provided on one outer wall of the fixed plate and the rotating plate;

[0016] By adopting the above technical solution, it is convenient for the fixed plate and the rotating plate to rotate relative to each other when the rotating plate is rotated.

[0017] Furthermore, a groove for storing the handwheel is provided on one inner wall of the arc-shaped through groove;

[0018] By adopting the above technical solution, it is easy for the handwheel to be embedded in the groove, ensuring that the inner wall of one side of the arc groove and the outer wall of one side of the arc platform are precisely fitted.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention, by adjusting the relative angle between the fixed plate and the rotating plate, can adapt to the included angle required for the docking of two busbar troughs. Under the limitation of the first and second limiting plates, the two busbar troughs are limited in the horizontal direction, which not only avoids misalignment at the welding point, but also ensures the stability of the busbar trough position during welding, preventing the busbar trough from shaking and causing incomplete welding. By using the push plate to apply a pushing force to the busbar troughs, it can ensure that the two busbar troughs are in close contact, ensure that the welding point is fully fitted, and improve the firmness of the joint after welding.

The arc platform 5 is rotatably connected to a ball screw 6. The nut seat on the ball screw 6 is fixedly connected to a limit plate 7 by screws. The limit plate 7 and the arc platform 5 are slidably connected to ensure the stability of the limit plate 7 when moving above the arc platform 5.

[0031] Side plates 11 are provided on one side of the outer wall of the rotating plate 4 and the fixed plate 2.
