Description
Technical field
The invention belongs to mine, engineering electric tool, particularly electric pick.
Background technology
Electric pick used mostly in the market is motor-driven eccentric ratio piston type, complex structure, and manufacturing cost is high, easily weares and teares, and the life-span is shorter, and it is not very convenient to keep in repair, and consumes energy high.
Summary of the invention
The present invention is based on the general principle of electromagnetism reclosing, provide a kind of mechanism simple, for ease of maintenaince, not easy to wear, the electromagnetism reclosing electric pick that the life-span is longer.
The technical scheme that the present invention adopts for its technical problem of solution is as follows.
A kind of reclosing electric pick proposed by the invention, comprises housing, slide rail, impact body, coil, spring, striker pin, guide pin bushing, it is characterized in that: coil, guide pin bushing and slide rail are fixed on housing; Striker pin is connected with impact body and inserts in guide pin bushing; The impact connector of impact body coordinates with slide rail, and can slide in slide rail; Spring one end is connected with guide pin bushing, and the other end is connected with impact body connector, and is enclosed within striker pin; Impact body flank adopts non-magnetic good conductor, and the length and width of its length-width ratio coil section bore are large; Lower coil is coaxial with upper coil, is wound around and keeps the consistent of magnetic flux, leave gap between upper lower coil, impact body flank can be held, and when impact body flank enters between upper lower coil, upper coil and impact body flank keep gap, and lower coil and impact body flank also keep gap.
The invention is characterized in that described impact body is by impacting connector and impact body flank forms, impact body flank is symmetrical relative to impact connector, can be a pair, or multipair; When impact body is at initial position, coil is vertical with impact body flank, and the geometric center of the axis overbump side wing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in the figure, a kind of reclosing electric pick proposed by the invention, comprise the parts such as housing 1, slide rail 2, impact body 3, coil 4, spring 5, striker pin 6, guide pin bushing 7, coil 1, guide pin bushing 7 and slide rail 2 are fixed on housing, striker pin 6 is connected with impact body 3 and inserts in guide pin bushing 7, impacts connector 31 and coordinates with slide rail 2, and can slide in slide rail 2, housing 1 is provided with the detector of monitoring impact body position, this detector is connected with control system.Spring 5 one end is connected with guide pin bushing 7, and the other end is connected with impact connector 31, and is enclosed within striker pin 6, and spring 5 is fixed and folding by the limit switch on housing 1; Impact body flank 32 adopts non-magnetic good conductor, and the length and width of its length-width ratio coil 4 cross section bore are large; Lower coil 41 is coaxial with upper coil 42, be wound around and keep the consistent of magnetic flux, gap is left between upper lower coil, impact body flank 32 can be held, and when impact body flank 32 enters between upper lower coil, upper coil 42 keeps gap with impact body flank 32, and lower coil 41 and impact body flank 32 also keep gap.Impact body flank 32 is symmetrical relative to impact connector 31, can be a pair, or multipair; When impact body 3 is at initial position, coil 4 is vertical with impact body flank 32, and the geometric center of the axis overbump side wing 32.Coil 4 is connected with power supply and control circuit, to control the break-make of electric current.
Its operation principle is summarized as follows: Fig. 5 is the impact body 3 initial position figure of patent detailed description of the invention of the present invention, and spring 5 is because there is the tensile force of pre-add, and after released, impact body 3 is to left movement and have certain initial velocity.Now, upper lower coil produces the consistent magnetic field of flow direction by power drives simultaneously, because impact body flank 32 is just in time between lower coil 41 and upper coil 42, now coil is coupled maximum with impact body flank 32, has blocked the continuous of magnetic flux, can not " reclosing ".When impact body flank 32 arrives position shown in Fig. 6, upper and lower two coils magnetic flux isolation by partial cancellation, the magnetic flux " reclosing " be originally truncated, the magnetic line of force of reclosing has stretching trend, and impact body flank 32 is promoted left.When impact body flank 32 arrives position shown in Fig. 7, enter " reclosing " of next stage, the position of impact body flank 32 is detected by sensor and is transferred to controller, is determined break-make and the opportunity of the power supply of coil by controller.Successively, until spring 5 is forced into a certain degree, striker pin 6 reaches range.Afterwards, impact body 3 to be rebounded initial position by spring 5, and enters next impact stroke.
The present invention is applicable to other and impacts industry, is such as applied in ail gun.
