Description

A clutch crankshaft clamping structure

technical field

The invention relates to the technical field of crankshaft clamping structures, in particular to a clutch crankshaft clamping structure.

Background technique

As the name suggests, the crankshaft is a shaft with a curved shape. The crankshaft is the most important part of the engine. It bears the force from the vertical bar and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. ;

Because the crankshaft has multiple inflection points and is not symmetrical along the axis, the geometric center of the crankshaft is not on the axis. When the crankshaft is placed laterally on a certain plane and no external force is applied to the crankshaft, the contact surface between the crankshaft and the plane is small. The crankshaft is easy to rotate, and the heavier parts on the crankshaft will turn to the lowest point under the force of gravity; in order to clamp the crankshaft at the required angle, it is necessary to set the workbench in contact with the curved surface of the crankshaft according to the required placement state of the crankshaft ; When clamping and processing the crankshaft, the staff need to constantly adjust their orientation to adapt to different processing surfaces of the crankshaft, especially when processing different processing surfaces of the crankshaft, the crankshaft needs to be removed and re-clamped repeatedly It is labor-intensive and inefficient.
