An intelligent sand cleaning treatment system for automobile flywheel castings

Abstract

The invention provides an intelligent sand cleaning treatment system for automobile flywheel castings, which includes a system body, a fixed block, a motor, a clamping mechanism and a dust accumulation mechanism, and is characterized in that: the left and right inner walls of the system body are rotated by a rotating shaft A fixed block is connected, and the motor is located on the outer surface of the right side of the system body. The fixed block on the right side is connected to the rotor of the motor through a rotating shaft. The inner cavity of the system body is provided with multiple sets of The clamping mechanism, the dust accumulation mechanism is located directly below the system body; the present invention can solve the problem of low efficiency of the working method, incomplete sand cleaning, high labor intensity and excessive vibration source, which easily mix waste sand in the air, causing The problem of serious environmental pollution.

Description

technical field [0001] The invention relates to the technical field of casting workpiece processing, in particular to an intelligent sand cleaning processing system for automobile flywheel castings. Background technique [0002] Casting is a metal thermal processing process. Casting is a method of casting liquid metal into a casting cavity that is suitable for the shape of the part, and after it is cooled and solidified, a method of obtaining parts or blanks; Low, high process flexibility, complex shapes and large castings can be obtained, which occupy a large proportion in mechanical manufacturing; [0003] As a kind of auto parts, the flywheel is a disc-shaped part with a large moment of inertia. It functions as an energy storage. For a four-stroke engine, work is done once every four piston strokes, that is, only the work stroke does work. The three strokes of exhaust, intake and compression all consume work, so the torque output by the crankshaft changes periodically, a...

[0003] As a kind of auto parts, the flywheel is a disc-shaped part with a large moment of inertia. It functions as an energy storage. For a four-stroke engine, work is done once every four piston strokes, that is, only the work stroke does work. The three strokes of exhaust, intake and compression all consume work, so the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft; existing The flywheel is mainly produced by casting. Since the side of the flywheel is gear-shaped and the surface is uneven, a large amount of raw sand will often be mixed in the casting. Therefore, the finished flywheel needs to be sand-cleaned.

[0004] Under the existing technical conditions, the solution to the problem of sand removal is: the method of manual knocking and washing: this work method is inefficient, the sand removal is not thorough, and the labor intensity is high; the method of shaking the sand is used: the method The sand cleaning effect of the working method is relatively high, but if the source is too large, it is easy to mix the waste sand in the air, causing serious environmental pollution.
