The present invention relates to an energy storage impact mechanism of an electric hammer. The present invention comprises a hammer anvil, an impact component and a swinging component, wherein the impact component and the swinging component are arranged on the back side of the hammer anvil; the back part of the impact component is connected with a connecting component; one end of the swinging component is connected with the connecting component; the back side of the connecting component is provided with a first cylinder which comprises a first cylinder sleeve and a first piston; either the first piston or the first cylinder sleeve is connected with the connecting component; when the swinging component moves backwards, gas in the first cylinder is pressed and stores energy; when the swinging component moves forwards, the energy released by the gas expansion has the function of increasing the speed of the first piston, so strong impact force is produced on the hammer anvil.
Description
Technical field
The present invention relates to the energy-accumulating impact mechanism of a kind of electric hammer, particularly electric hammer.
Background technology
Thereby existing electric hammer adopts the motion cylinder that piston is produced the speedup effect usually and makes the effect that hammer anvil has increases impact capacity, promptly the rear side at hammer anvil is provided with cylinder, its piston and hammer anvil are adjoining, the cylinder rear side is provided with a fork, and cylinder jacket is connected with this fork, and fork is driven by a transmission mechanism and moves reciprocatingly, when cylinder jacket is moved with fork, piston also moves reciprocatingly thereupon, thus the piston impact hammer anvil, as shown in Figure 8.Though this method can produce certain percussion to hammer anvil, because of energy storage gas more limited to the speedup effect that piston produces, so piston is also smaller to the impact capacity of hammer anvil.Also have a kind of electric hammer in addition, it produces the speedup effect by an elastic rocking beam to piston, thereby impacts hammer anvil, as shown in Figure 7.Because elastic rocking beam elasticity in use for some time weakens, the life-span is limited, is difficult to its elastic strength of control, so use elastic rocking beam to make the piston speedup very unreliable, often causes trouble to work.
Summary of the invention
The object of the invention provides a kind of energy-accumulating impact mechanism of electric hammer, and its energy storage effect increases.
Technical scheme of the present invention is: a kind of energy-accumulating impact mechanism of electric hammer comprises that the hammer anvil that is slidingly arranged in the hammer anvil cover, the hammer anvil that is arranged on described hammer anvil rear side overlap interior impact part, the swing component that is connected with transmission mechanism.The rear portion of described impact part is connected with a connection piece, and an end of described swing component is connected on the described connector.The rear side of described connector is provided with first cylinder, and described first cylinder comprises first cylinder sleeve and be inserted in the interior first piston of described first cylinder sleeve slidably that one of them of described first piston and described first cylinder sleeve is connected with described connector.
The present invention compared with prior art, has following advantage: the connector and first cylinder that set gradually an end that is connected with swing component at the rear side of impact part, by swing component move backward make in first cylinder gas by compression and energy storage, thereby it is proal simultaneously to the effect of connector generation speedup at swing component, so just can produce very strong percussion to hammer anvil, use also very reliable, and the gas in the cylinder can play the better damping effect to swing component, can increase its service life.

The specific embodiment
Specify below in conjunction with each accompanying drawing.
Referring to accompanying drawing 1-accompanying drawing 4, a kind of energy-accumulating impact mechanism of electric hammer comprises that the hammer anvil 1 that is slidingly arranged in the hammer anvil cover 7, the hammer anvil that is arranged on described hammer anvil 1 rear side overlap the impact part in 7, the swing component 3 that is connected with transmission mechanism.The rear portion of described impact part is connected with a connection piece 9, and an end of described swing component 3 is connected on the described connector 9.Have pendulum hole 8 on the described connector 9, the top of described swing component 3 is inserted in the described pendulum hole 8.The rear side of described connector 9 is provided with first cylinder, described first cylinder comprises first cylinder sleeve 4 and is inserted in first piston 2 in described first cylinder sleeve 4 slidably that one of them of described first piston 2 and described first cylinder sleeve 4 is connected with described connector 9.Usually, described first piston 2 is connected with described connector 9, forms first air chamber 10 (as shown in accompanying drawing 1-accompanying drawing 4) of sealing between described first piston 2 and described first cylinder sleeve 4.
Impact part can adopt multiple structure, introduces two kinds of embodiment below:
Embodiment one: referring to accompanying drawing 1-accompanying drawing 2, accompanying drawing 5, described impact part is a percussion hammer 12.But swing component 3 compresses the gas in first cylinder when moving backward, storage power plays the better damping effect to swing component 3 simultaneously; When swing component 3 travelled forward, the gas in first air chamber 10 expanded and discharges its energy stored, first piston 2 is played the speedup effect, thereby connector 9 is played the speedup effect, has so just produced very strong impulsive force.
Embodiment two: referring to accompanying drawing 3-accompanying drawing 4, accompanying drawing 6, be to strengthen impulsive force, described impact part is set to second cylinder, and described second cylinder comprises second cylinder sleeve 5, is inserted in second piston 6 in described second cylinder sleeve 5 slidably.Described second cylinder sleeve 5 is connected with described connector 9 with one of them of described second piston 6, in the embodiment shown in the accompanying drawing 3-accompanying drawing 4, described connector 9 is connected with described second cylinder sleeve 5, forms second air chamber 11 of sealing between described second piston 6 and described second cylinder sleeve 5.When swing component 3 moved backward, the gas in first air chamber 10 by compression and storage power is similar to embodiment one; And swing component 3 is proal the time, and second cylinder sleeve 5 travels forward and makes gas pressurized storage power in second air chamber 11, and second piston 6 is produced the speedup effects, makes that like this impulsive force of 6 pairs of hammer anvils 1 of second piston is stronger.And when swing component 3 was reciprocating, the gases in first air chamber 10 and second air chamber 11 can play better damping effect to swing component 3, have increased the service life of swing component 3.
Described swing component 3 also can be torsion spring, utilizes its elasticity, can produce stronger speedup effect by the impact parts, makes its impulsive force stronger.
