Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to a welding fixture for a casing frequency converter bracket. Background Art

[0002] As an electronic device widely used in the field of industrial automation, the inverter casing usually needs to be welded to the bracket. The inverter casing bracket is generally made of metal materials, such as steel and aluminum alloy. The structural design of this type of bracket is usually simple, while meeting the strength and stability requirements, minimizing the use of materials and saving space.

[0003] At present, the inverter casing bracket usually adopts the traditional manual welding method, which mainly relies on the workers' experience and manual operation, and lacks precise positioning tools. As a result, during the welding process, it is difficult to accurately align the various components of the bracket, and position deviations are very likely to occur, resulting in low dimensional accuracy of the bracket after welding, which in turn affects its installation and use in the inverter. For example, when there is a large error in the bracket size, it may not be able to perfectly match the casing, thereby affecting the overall stability and performance of the equipment. In view of this, a casing inverter bracket welding fixture is proposed to improve the dimensional accuracy of the product. Summary of the Invention

[0006] The bracket square tube 1 includes a square tube body, a groove and a limiting hole. The groove is opened on the outside of the square tube body, and the limiting hole is opened at the lower end of the square tube body.

[0007] Preferably, the support legs are made by bending a welding base, and the welding base is made of galvanized steel plate.

[0008] Through the above technical solution, a support leg is set up. The support leg is made by bending the welding base, has high structural strength, provides support for the welding base, and makes the welding base easy to lift. The welding base is made of galvanized steel plate, which is corrosion-resistant, oxidation-resistant, has high structural strength and is relatively durable.

[0009] Preferably, two identical square grooves are provided.

[0010] Through the above technical solution, a square groove is opened in the welding base. Before welding the chassis inverter bracket, the staff reaches into the square groove with their hands to lock the positioning bolts and the positioning hole threads to pave the way for subsequent bracket positioning. The square groove reduces the quality of the welding base and facilitates operation.

[0011] Preferably, the positioning bolt is threadedly connected to the positioning hole, and the positioning bolt is a hexagon socket bolt.

[0012] Through the above technical solution, the positioning bolt is a hexagon socket bolt, which is very convenient to assemble and disassemble.

[0013] Preferably, the grooves are evenly arranged on the outside of the square tube body.

[0014] Through the above technical solution, a groove is opened on the outside of the square tube body. When welding, the bracket square tube is placed on the welding base. Through the groove, it can be observed whether the limit hole and the positioning bolt are aligned, thereby improving the convenience of operation.

[0015] Preferably, the limiting hole is adapted to the positioning bolt, and the limiting hole and the positioning bolt are plug-connected.

[0016] Through the above technical solution, the limiting hole is plugged into the positioning bolt, and the positioning bolt positions the bracket square tube 1. The bracket square tube 2 is positioned in the same way and placed on the upper end of the welding base.

[0017] Preferably, the bracket square tube 1 is provided with two symmetrical and identical bracket square tubes, and the bracket square tube 2 and the bracket square tube 1 are perpendicular to each other.

[0018] Through the above technical solution, the bracket base plate is placed between the two bracket square tubes 1 during welding, and the limiting effect of the positioning bolts makes the gap between the bracket base plate and the bracket square tube 1 smaller, and the matching degree between the bracket square tube 1 and the bracket square tube 2 is high.

[0019] Compared with the prior art, the present invention provides a welding fixture for a chassis inverter bracket, which has the following beneficial effects:

[0020] 1. The welding fixture for the inverter chassis bracket is equipped with a support leg, which is made by bending the welding base. The support leg has high structural strength and provides support for the welding base, making the welding base easy to hoist. The welding base is made of galvanized steel plate, which is corrosion-resistant and oxidation-resistant, with high structural strength and durability.

[0021] 2. The casing inverter bracket welding fixture has a square groove on the welding base. Before welding the casing inverter bracket, the staff reaches into the square groove with their hands and locks the positioning bolts with the positioning hole threads to pave the way for the subsequent bracket positioning. The square groove reduces the quality of the welding base and is convenient for operation. A groove is provided on the outside of the square tube body. When welding, the bracket square tube 1 is placed on the welding base. The groove can be used to observe whether the limiting holes and the positioning bolts are aligned, thereby improving the convenience of operation. The limiting holes and the positioning bolts are plugged into and connected. The positioning bolts position the bracket square tube 1, and the bracket square tube 2 is positioned on the upper end of the welding base in the same way. When welding, the bracket base plate is placed between the two bracket square tubes 1. The limiting effect of the positioning bolts makes the gap between the bracket base plate and the bracket square tube 1 smaller, and the bracket square tube 1 and the bracket square tube 2 have a high matching degree. This welding fixture is suitable for installation of welded parts with small installation requirements, which reduces the offset of the mounting holes during welding, thereby improving the dimensional accuracy of the product.
