[0021] 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. Example

[0022] See also Figure 1-4 This embodiment provides the following technical solutions: a welding tool for a bridge housing oil baffle, comprising a positioning plate 1 and a positioning seat 2, wherein the positioning plate 1 is arranged on the top of the bridge housing body 3, and the positioning plate 1 is detachably connected to the bridge housing body 3. In some embodiments, a first positioning hole 6 is provided on the positioning plate 1, and the first positioning hole 6 is for inserting a first bolt 7 to fix the positioning plate 1 on the bridge housing body 3. The positioning plate 1 can be disassembled and assembled on the bridge housing body 3 by the provided first bolt 7.

[0023] The positioning seat 2 is detachably connected to the positioning plate 1. In some embodiments, a second positioning hole 8 is provided on the top of the positioning seat 2. The second positioning hole 8 is for inserting a second bolt 9 to fix the positioning seat 2 on the positioning plate 1. The positioning seat 2 can be disassembled and assembled on the positioning plate 1 through the provided second bolt 9.

[0024] The other end of the positioning seat 2 extends to the interior of the bridge housing body 3. The side of the positioning seat 2 that is opposite to the inner wall of the bridge housing body 3 is detachably connected to the oil baffle body 4. In some embodiments, a third positioning hole 10 is provided at the bottom of the positioning seat 2. The third positioning hole 10 is for inserting a third bolt 11 to fix the bridge housing body 3 on the positioning seat 2. The oil baffle body 4 can be fixedly installed and disassembled on the positioning seat 2 through the provided third bolt 11, thereby completing the position limitation of the oil baffle body 4 by limiting the position of the positioning seat 2.

[0025] The positioning seat 2 and the positioning plate 1 cooperate together to form a fixed structure of the oil baffle body 4. Through the arrangement of the positioning plate 1 and the positioning seat 2, the oil baffle body 4 can be conveniently fixed to a specific position on the inner wall of the bridge housing body 3, and then the oil baffle body 4 is manually welded and fixed to the bridge housing body 3, which not only makes it convenient for workers to operate and fix the oil baffle body 4, but also makes it convenient for workers to disassemble and assemble the tooling, and improves the efficiency of welding the oil baffle body 4.

[0026] In some embodiments, the positioning plate 1 and the positioning seat 2 form an "L"-shaped structure, which makes it convenient to fix the positioning plate 1 on the top of the bridge housing body 3. The position of the oil baffle body 4 on the positioning seat 2 is directly opposite to the specific position of the oil baffle body 4 on the inner wall of the bridge housing body 3. This not only increases the accuracy of the installation of the oil baffle body 4, but also improves the stability of the oil baffle body 4 on the tooling.

[0027] In some embodiments, an arc-shaped groove 5 is provided on the side of the positioning plate 1 away from the positioning seat 2. The arc-shaped groove 5 is adapted to the inner wall of the bridge housing body 3. The positioning plate 1 is clamped on the bridge housing body 3 through the arc-shaped groove 5. The arc-shaped groove 5 increases the adaptability of the positioning plate 1 fixed on the bridge housing body 3, thereby increasing the stability of the positioning plate 1 on the bridge housing body 3.

[0028] In some embodiments, a pad 12 is provided on the side of the positioning seat 2 away from the positioning plate 1, and a fourth positioning hole 14 for inserting the third bolt 11 is provided on the pad 12. By providing the pad 12, the contact area between the third bolt 11 and the positioning seat 2 is increased, thereby increasing the stability of the oil baffle body 4 on the positioning seat 2.

[0029] The working principle of the present utility model is as follows: when welding the oil baffle body 4 to a specific position on the inner wall of the bridge housing body 3, first install the oil baffle body 4 on the inner side of the positioning seat 2, and fix the oil baffle body 4 on the positioning seat 2 through the third bolt 11, and then drag the positioning plate 1 so that the positioning plate 1 drives the positioning seat 2 and the oil baffle body 4 to move, and then fix the positioning plate 1 to the bridge housing body 3 through the first bolt 7. After the positioning plate 1 is fixed to the bridge housing body 3, the oil baffle body 4 is fitted on the inner wall of the bridge housing body 3, and then manually welded to the inner wall of the bridge housing body 3. After the welding is completed, disassemble and assemble the first bolt 7 and the third bolt 11, thereby removing the tooling from the bridge housing body 3.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
