Abstract
The invention relates to a low noise low recoil electric breaker that belongs to tool field. It fixes the motor that has installed eccentric block, and the active bearing on two plate springs, which connect to base, impacting bar and stem. The impacting bar could slide in the shafting liner and has vibration reduction spring and location limited spring. When the eccentric block and the components are rotating driven by the motor in XZ plane, the stem would be driven to rotate along the Z shaft by the disassembling function of the plate spring and produce impact force. The inner of the mechanism has no impact, so there is no noise. The stem impact force is coursed by the moment of the eccentric block and the rotating speed of the motor, so the recoil is low.
Description
Technical field
The invention belongs to mine, engineering electric tools, particularly electric pick class.
Background technology
Used in the market motor-driven pick class mine, engineering machinery mainly contain two kinds, the 1st, with the compressed air source, i.e. pneumatic pick, it must be furnished with air compressor or near compressed gas source is arranged; The 2nd, electric pick.Electric pick mostly is the eccentric ratio piston type, is the knocking core bar with the piston, and drill steel is thumped.These two kinds of pick classes all need the workman could produce impact force with the hand application pressure in use, in-house generation bump sends very big noise, produces very big recoil impact force, internal mechanism is easy to damage, and has increased maintenance load and the application life that has reduced complete machine.And noise and recoil also endanger the healthy of operator, and noise is contaminated environment also, near resident's the life health influence.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above pick class machinery, and a kind of electric pick with low noise and weak recoil of novelty is provided, it is simple in structure, and is reliable, easy to use, cost is low, and volume is little, and is in light weight, impact is big, maintenance capacity is little, and is easy to maintenance, need not the operator during use and exerts pressure and just can produce impact force.
The technical solution adopted for the present invention to solve the technical problems is: the motor of eccentric block or movable axis bearing will be housed be fixed on and have only resilient two flat spring one ends of X-direction in the XZ Plane of rotation; two flat spring other ends are connected with base; base is connected with impact bar; impact bar is connected with drill steel; slide block on the impact bar can with the hard-wired axle sleeve of shell in slide; spring damping is up and down arranged on the impact bar, and keep impact bar and go up the position of each member when shutting down.The connected mode of motor and flat spring has two kinds, the one, the direct junction plate spring of motor stator, eccentric block directly is fixedly mounted on the motor shaft, the 2nd, motor is fixed on the shell, motor shaft connects with movable axis by soft shaft coupling, the movable axis bearing is installed on the movable axis, and flat spring one end is fixed on the movable axis bearing, and the other end is fixed on the base.When driven by motor eccentric block and assembly rotate on the XZ plane, the circular vibration of eccentric block and assembly can be decomposed into the vibration of X-direction and Z-direction, because flat spring is at the elastic reaction of X-direction, make the free vibration on X-direction of eccentric block and assembly, and since flat spring in the rigidity effect of Z-direction and the guide effect of slide block and axle sleeve, eccentric block and assembly finally drive drill steel and vibrate on Z-direction, produce impact force.
The present invention compared with prior art, its advantage is: the circular vibration of eccentric block and assembly directly drives impact bar and drill steel and produces impact force under the effect of flat spring, simple in structure, in-house nothing is impacted, therefore there is not impact noise, the size of drill steel impact force apply external force without the operator, so recoil is small and weak by the moment and the rotating speed of motor decision of eccentric block.
