Description

technical field [0001] The invention relates to an electro-permanent magnet high-frequency impact power mechanism, specifically a high-frequency impact power component, which is used to support impact engineering machinery used in construction, mining and other industries, such as electric hammers, rock drills, etc., and belongs to engineering machinery accessories technology field. Background technique [0002] Impact construction machinery works on the principle of impact crushing. When working, the piston makes high-frequency reciprocating motion. Under the action of impact force, the drill bit breaks and shears hard materials such as concrete, masonry, ore. Traditional high-frequency impact power sources are divided into electric, pneumatic, hydraulic and internal combustion engine drives. Among them, the pneumatic type uses compressed air, hydraulic pressure and oil pressure to drive the piston. Since these two power structures require external power input, the mechanis...

Problems solved by technology

Traditional high-frequency impact power sources are divided into electric, pneumatic, hydraulic and internal combustion engine drives. Among them, the pneumatic type uses compressed air, hydraulic pressure and oil pressure to drive the piston. Since these two power structures require external power input, the mechanism is huge and the components Various, not suitable for miniaturized portable design, especially not suitable for field work under harsh conditions, and the internal combustion type that drives the piston with the explosive force of gasoline, and the electric type that drives the piston with the crankshaft and connecting rod driven by the electric motor, although due to the use of fuel 1. Electricity is used as the power source, and the structure is relatively simple, but a large number of mechanical transmission structures make the vibration intensified, the power loss is obvious, and the impact oscillation frequency is low, and the impact force is insufficient.
