Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft production equipment, in particular to a supporting device for crankshaft marking. Background Art

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] Crankshaft pneumatic marking is a process that uses pneumatic equipment to mark or print on the surface of a crankshaft. This technology uses compressed air as a power source to control the movement of the marking head through a cylinder or other pneumatic actuator. The marking head is usually made of wear-resistant materials, such as carbide or special steel, to ensure durability and accuracy during the marking process. The content of the mark usually includes the production date, batch number, part number or other key information, which helps with production tracking and quality control.
