Description

Technical Field

[0001] This application relates to the technical field of crankshaft machining, and in particular to a crankshaft blank surface treatment device. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, resulting in bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, operate evenly, and have good balance. During the power stroke, the crankshaft first converts the thrust transmitted from the connecting rod into rotational torque, which drives the vehicle through the transmission system. Then, utilizing the rotational inertia of the crankshaft and flywheel, it drives the piston up and down via the connecting rod to complete auxiliary strokes such as exhaust, intake, and compression, preparing for the next power stroke.

[0003] In the manufacturing process of crankshafts, surface treatment of crankshaft blanks is a crucial step. Traditional surface treatment methods for crankshaft blanks have many drawbacks. For example, manual grinding is not only inefficient but also difficult to guarantee consistent grinding quality, often resulting in uneven grinding. In the cleaning stage, some simple cleaning equipment cannot thoroughly remove oil and impurities from the blank surface, affecting subsequent processing and product performance. If drying is not timely or ineffective, it can lead to rusting of the crankshaft blank, increasing production costs. Currently available surface treatment devices on the market are often single-function and cannot achieve integrated operation of grinding, cleaning, and drying. They require transferring workpieces between multiple devices, increasing processing time and costs while reducing production efficiency. Therefore, there is an urgent need for a surface treatment device for crankshaft blanks that can perform diversified treatments. Utility Model Content
