Description

Technical Field

[0001] The present invention relates to the technical field of differential housings, and in particular to a forging process for a new energy vehicle differential housing and a preparation method thereof. Background Art

[0002] The automobile differential is the main part of the drive axle. Its function is to transmit power to the two half-axles while allowing the two half-axles to rotate at different speeds, so that the wheels on both sides can travel at unequal distances in a pure rolling form as much as possible, reducing the friction between the tires and the ground. The differential housing is an important structure used to protect the internal components of the differential so that it can work safely and effectively for a long time. The existing differential housing is generally divided into two parts, the differential housing body and the differential housing cover, and the two housings are fixed together by welding. The existing differential housing welding device has a simple structure and poor welding effect, which cannot meet the user's use requirements.

[0003] When a differential case welding platform described in Patent No. CN105817789A is used, the case cannot be fixed quickly, the operation is complicated, and only a single case can be processed at a time, resulting in low processing efficiency. Summary of the invention

Then transport the shell in the feed rail to the installation station. At this time, the shell falls above the lifting plate. At this time, the lifting cylinder starts to drive the lifting plate to move downward, driving the shell to move downward and fall into the inner cavity of the installation station. Then, the limit cylinder in the limit frame extends out and abuts against the surface of the shell to position the shell.

[0008] Step 2: Place the shell cover on top of the shell and adjust the position;

[0009] Step 3: The rotating table continues to rotate, driving the shell to rotate to the welding frame. At this time, the first welding table in the pillar extends out and is set on one side of the shell. At this time, the motor drives the rotating rod to rotate, driving the second welding table to flip and set on the other side of the shell. The first welding table and the second welding table wrap the shell to weld the shell and the shell cover;

[0010] Step 4: When welding, the driving motor is started to drive the driving gear to rotate, the driving gear drives the driven gear to rotate, the lifting rod drives the shell to rotate, and the lifting rod drives the shell to rotate, and the angle of the shell is adjusted to facilitate the first welding station and the second welding station to weld the shell;

[0011] Step 5. After welding is completed, the first welding table and the second welding table are retracted, and then the rotating table is rotated to rotate the welded shell to the discharge guide rail, and output through the discharge guide rail to complete the welding.
