Description
Technical Field
The utility model relates to the technical field of drilling fixtures, in particular to a differential case drilling fixture.
Background
The differential mechanism of the automobile is a mechanism which can enable left and right (or front and rear) driving wheels to rotate at different rotating speeds. Mainly comprises a left half shaft gear, a right half shaft gear, two planet gears and a gear carrier. The function is that when the automobile turns or runs on an uneven road surface, the left wheel and the right wheel roll at different rotating speeds, namely, the pure rolling motion of the driving wheels at two sides is ensured. The differential is provided for adjusting the difference in the rotational speeds of the left and right wheels. In four-wheel drive, all the wheels must be connected to drive four wheels, if the four wheels are mechanically connected, the vehicle cannot rotate at the same speed when the vehicle runs on a curve, and in order to make the curve running rotation speed of the vehicle substantially consistent, an intermediate differential is added to adjust the rotation speed difference between the front wheel and the rear wheel. The common differential mechanism consists of planetary gears, a planetary gear carrier, a half axle gear and other parts. The planetary carrier is a differential case, belongs to an important part of a differential, and is widely applied.
A conventional automobile differential requires eight holes to be uniformly machined in the differential case in the circumferential direction. The machining precision of the holes is high, and the existing differential case drilling clamp only clamps a part of the edge of the differential case, so that sometimes the fixation is insufficient, the differential case generates vibration and then deviates during drilling, the deviation of the hole precision on the differential case is caused, and the machining precision is influenced.
