Description

Technical Field

[0001] The utility model relates to a welding device, in particular to a bridge housing inner cavity welding splash protection tooling. Background Art

[0002] At present, the axle processing industry has no preventive measures for spot welding of the two half shells and base welding of the inner cavity of the bridge shell. Welding spatter falls into the inner cavity of the bridge shell. After the bridge shell is gas cut, it is manually cleaned with steel shovels and wire brushes, but the cleaning effect is poor. The labor intensity is high, the production pace is slow, and a lot of spatter adheres to the inner wall of the bridge shell and cannot be removed, which reduces the life of the subsequent assembled bridge shell gears and creates a driving safety hazard. Utility Model Content

[0003] In order to solve the problems in the related art, the utility model provides a bridge housing inner cavity welding spatter protection tooling, which solves the problem that welding spatter directly adheres to the bridge housing inner cavity and the manual labor intensity is high.

[0004] In order to solve the above problems, the following technical solutions are provided:

[0005] The bridge shell inner cavity welding spatter protection tooling of the utility model comprises two U-shaped plates arranged in parallel, the openings of the U-shaped plates are arranged in a direction away from the other U-shaped plate, and an adjustment mechanism is provided between the two U-shaped plates. The adjustment mechanism is used for the mouth of the U-shaped plate to abut against the inner cavity of the bridge shell after the tooling enters the bridge shell.

[0006] In the above scheme, a U-shaped plate is provided to block the spatter generated during welding, thereby solving the problem of welding spatter adhering to the inner wall of the bridge housing, greatly reducing the difficulty of cleaning, and solving the problem of high manual labor intensity.

[0007] There are two adjustment mechanisms, which are respectively located between the two ends of the two U-shaped plates; the adjustment mechanism includes a connecting column, which is perpendicular to the transverse part of the U-shaped plate, and circular holes are provided on the transverse parts of the two U-shaped plates corresponding to the two ends of the connecting column. The two ends of the connecting column respectively pass through the corresponding circular holes and extend into the U-shaped plate. The connecting column and the U-shaped plate are slidably matched, and a limit head is fixed on the section of the connecting column located in the U-shaped plate. The width of the limit head is greater than the diameter of the circular hole. A compression spring is provided on the connecting column located between the two U-shaped plates, and the compression spring is against the U-shaped plate.

[0008] In the above scheme, the compression spring is arranged to reset the U-shaped plate so that the mouth of the U-shaped plate abuts against the inner wall of the bridge housing.

[0009] There are two connecting columns, which are arranged in parallel. The connecting columns are double-headed studs, and the two ends of the double-headed studs are respectively located in the corresponding U-shaped plates. Hexagonal nuts are provided on both ends of the double-headed studs. The double-headed studs are threadedly connected to the hexagonal nuts, and the hexagonal nuts are the limit heads.

[0010] In the above scheme, studs are used as connecting columns and hexagonal nuts are used as limiting heads. Both studs and hexagonal nuts are standard parts and can be purchased directly without customization, which greatly reduces production costs.

[0011] The outer side surfaces of the transverse parts of the U-shaped plate are provided with handles, and the handles are located at both ends of the U-shaped plate.

[0012] In the above scheme, the handle is provided to adjust the position of the workpiece in the bridge housing and to take the workpiece out of the bridge housing.

[0013] The above solution has the following advantages:

[0014] 1. The axle housing inner cavity welding spatter protection tooling of the utility model comprises two parallel U-shaped plates, the opening of the U-shaped plate is arranged in a direction away from the other U-shaped plate, and an adjustment mechanism is provided between the two U-shaped plates. The adjustment mechanism is used to make the opening of the U-shaped plate abut against the inner cavity of the axle housing after the tooling enters the axle housing. Through the arrangement of the U-shaped plate, the U-shaped plate is used to block the spatter generated during the welding process, ensuring that the welding spatter will not be adhered to the inner cavity wall of the axle housing in large quantities, greatly reducing the difficulty of cleaning and reducing the labor intensity.

The adjustment mechanism includes a connecting column, both ends of which pass through the circular holes corresponding to the horizontal part of the U-shaped plate respectively, and the connecting column section located in the U-shaped plate is fixedly connected with a limit head, and a compression spring is provided on the connecting column located between the two U-shaped plates. The compression spring is used to reset the U-shaped plate so that the mouth of the U-shaped plate is against the inner wall of the bridge housing. The connecting column is a double-headed stud, and the two ends of the double-headed stud are respectively located in the corresponding U-shaped plates. Hexagonal nuts are provided on both ends of the double-headed stud, and the hexagonal nuts are the limit heads. The double-headed stud is used as the connecting column and the hexagonal nut is used as the limit head. The double-headed stud and the hexagonal nut are standard parts and can be purchased directly without customization, which greatly reduces the production cost. A handle is provided on the outer side of the horizontal part of the U-shaped plate, which is used to adjust the position of the workpiece in the bridge housing and remove the workpiece from the bridge housing.
