Description

Technical Field

[0001] The utility model belongs to the technical field of protection devices, and in particular relates to a bridge housing shell wheel core support welding protection device. Background Art

[0002] The transmission axle housing is an important part of the vehicle, and the wheel core support not only plays a role in installation and positioning, but also affects the transmission ratio of the vehicle. However, since the wheel core support not only requires low-temperature processing, but also has low high-temperature resistance, the quality of the wheel core support will be affected when the welding slag splashes on it during welding. In addition, when removing the welding slag, it is impossible to ensure that the wheel core support maintains the original part accuracy, which will have a certain impact on subsequent production and processing as well as actual use. Therefore, a device is needed to protect the wheel core support during welding. Utility Model Content

[0022] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0023] Example:

[0024] like Figure 1-7 As shown, a bridge housing shell wheel core support welding protection device includes a protective sleeve 1 and a fixing plate 2, wherein the protective sleeve 1 includes a protecting portion 3 and a connecting portion 4, wherein one side of the connecting portion 4 is connected to the protecting portion 3 through a limiting member 5, and the other side of the connecting portion 4 is connected to the fixing plate 2.

[0025] The protection part 3 is cylindrical, one end of the protection part 3 is provided with an opening, and the other end of the protection part 3 is a sealing end, which is used to protect the wheel core supporting structure.

[0026] The stopper 5 is annular, and a hole A6 is arranged on the stopper 5. The wheel core supports the stopper 5 and extends into the protective cover 1. The stopper 5 is used to adapt to the wheel core support structure of the bridge housing, and the protective cover 1 is fixed on the wheel core support structure through the stopper 5 as a fixing surface.

[0027] The fixing plate 2 is provided with a groove 7 , and the fixing plate 2 is connected to the limiting member 5 via bolts 8 .

[0028] The connecting portion 4 is in a circular shape, and the inner diameter of the connecting portion 4 is larger than the outer diameter of the protecting portion 3 . This arrangement is used to adapt to the axle housing shell wheel core supporting structure.

[0029] The outer diameter of the limiting member 5 is greater than the outer diameter of the protecting portion 3 , and plays a role in limiting the length of the wheel core supporting structure extending into the protecting portion 3 .

[0030] The fixing plate 2 is arc-shaped, and a hole B9 is arranged on the fixing plate 2. Two fixing plates 2 are arranged, which are placed inside the connecting portion 4 and are in contact with and connected to the connecting portion 4. The two fixing plates 2 are spliced ​​into an annular structure, and the two grooves 7 form a circular hole structure, so that the wheel core support passes through the circular hole structure and then extends into the protective sleeve 1.

[0031] After the wheel core support is installed on the bridge housing, first wrap the wheel core support with the protective cover 1, and place the protective cover 1 against the flange at one end of the bridge housing, then place the fixing plate 2 on the inner side of the flange, and use the bolt 8 to pass through the hole B9, the corresponding hole on the bridge housing shell, and the hole A6 in sequence, and then connect the corresponding fastening nut and tighten it to fix the protective device on the bridge housing.
