Description

A anchor clamps for differential mechanism shell part

Technical Field

The utility model relates to a differential mechanism brick mould field, in particular to anchor clamps for differential mechanism shell part.

Background

The automobile differential mechanism can realize a mechanism that left and right (or front and rear) driving wheels 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. This adjustment of the differential is automatic and involves the "least power consumption principle", i.e. the state in which all the objects on the earth tend to consume the least power. For example, when a bean is put into a bowl, the bean will automatically stay at the bottom of the bowl and never stay on the wall of the bowl, because the bottom of the bowl is the lowest energy position (potential energy), and the bottom of the bowl is automatically selected to be static (minimum kinetic energy) and not to move continuously. And in the same way, the wheels automatically tend to the state with the lowest energy consumption when turning, and the rotating speeds of the left and right wheels are automatically adjusted according to the turning radius. If the driving wheels at two sides of the driving axle are rigidly connected by a whole shaft, two wheels can only rotate at the same angle. Thus, when the automobile is driven in a steering mode, the outer wheels move a larger distance than the inner wheels, so that the outer wheels roll and slide, and the inner wheels roll and slide. Even when the automobile is running straight, the wheel slips due to uneven road surface or uneven rolling radius of the tire (tire manufacturing error, wear difference, load variation, or air pressure variation) even though the road surface is flat. When the hole machining device is used for machining, the distance between the center of the hole and the end face and the included angle between holes are mainly guaranteed, and the holes are located on the circumference of the outer diameter of a part. And in the early stage of machining, clamping is not carried out by using a clamp, clamping is carried out by adopting a vice, and after one hole is drilled, the hole is loosened and clamped again to complete the next hole.

However, in the prior art, as the clamp is not used for clamping in the early stage of machining, the vice is used for clamping, and after one hole is drilled, the hole is loosened and clamped again to complete the next hole. Therefore, repeated clamping is inevitable, the labor intensity of operators is high, and the efficiency is not high.
