Description
Technical field
The invention belongs to field of power tools, relate to a kind of double-crankshaft damping device of reciprocating electric tool, it utilizes motor to make the processing device to-and-fro motion such as saw blade, carries out processing and rewind.
Background technique
Reciprocating electric tool is the large class of one in electric tool, is widely used in timber, plastics and steel pipe processing etc.Although existing various reciprocating electric tool in the market, the undesirable and operator of instrument rapid wear, processing effect is caused to produce fatigue compared with big bang because it exists eventually.
Summary of the invention
The object of this invention is to provide a kind of damping device, reciprocating electric tool is had, and vibrations little, long service life, wear-out part such as are convenient to change, machining locus is desirable at the advantage, the energy of zero load when making full use of rewind.
The present invention specifically discloses a kind of double-crankshaft damping device of reciprocating electric tool, comprise framework, guiding device and sliding device, sliding device is arranged in framework, can slide along guiding device, between sliding device and framework, be provided with damping device, framework and sliding device link together by damping device, it is characterized in that, also comprise driving gear crank and driven gear crank, driving gear crank and driven gear crank and sliding device form double-crank slide mechanism.
Further, two groups of rubber bushs and metal sleeve are separately fixed on the bent axle of driving gear crank and driven gear crank by circlip for shaft.
Wherein, described sliding device is hollow structure, the bent axle of driving gear crank and driven gear crank is inserted in the hollow open of sliding device, motor drives driving gear crank to rotate by rotating shaft, driving gear crank drives driven gear crank to rotate by gear pair, thus promotion sliding device pumps.
Wherein, described guiding device is two guide rods, is fixedly connected on framework, and sliding device can slide up and down along guide rod.
Wherein, described framework comprises housing, lower housing and stop sleeve, and upper housing, lower housing and two stop sleevees are linked together by two groups of bolt groups.
Further, also comprise energy-storaging spring, its one end is connected with upper housing or lower housing, and the other end is connected with housing of electric tool.
Further, described damping device is yielding rubber or damping spring.
Further, adjustment pad is set in stop sleeve side, the pretightening force of damping device can be regulated by increase and decrease adjustment pad.
Further, upper housing or lower housing are connected with processing device.
The invention has the beneficial effects as follows, in being processed by reciprocating electric tool, the rigid impulse of load becomes soft impulse by damping device, the advantages such as it is less that this transmission device has vibrations compared with existing structure, and longer service life, machining locus are better.

Embodiment
Below in conjunction with accompanying drawing, the present invention is specifically described.
As Figure 1-4, upper housing 1, lower housing 8 and two stop sleevees 5 are linked together by two groups of bolt groups 3, two guide rods 2 are fixedly connected on housing 1, lower housing 8, slide block 6 is arranged between housing 1 and lower housing 8, slide block 6 can slide up and down along guide rod 2, slide block 6 and be provided with buffer unit 4 between upper housing 1 and lower housing 8, thus slide block 6 and upper housing 1, lower housing 8 are combined into an entirety.Damping device can be yielding rubber or damping spring.
Two groups of rubber bushs 13 and metal sleeve 12 are separately fixed on the bent axle of driving gear crank 9 and driven gear crank 10 by circlip for shaft 14.Driving gear crank 9 and driven gear crank 10 form slidercrank mechanism with slide block 6, slide block 6 is hollow structure, the bent axle of driving gear crank 9 and driven gear crank 10 is inserted in the hollow open of slide block, and upper housing 1 or lower housing 8 are connected with processing device 11.
During work, motor drives driving gear crank 9 to rotate by the rotating shaft of driving gear crank 9, driven gear crank 10 is driven to rotate by gear pair, the bent axle of driving gear crank 9 and driven gear crank 10 horizontally slips in slide block, thus promotion slide block 6 pumps, slide block 6 drives upper housing 1 by yielding rubber or damping spring 4, lower housing 8 moves, and the final processing device 11 that drives pumps.
Adjustment pad 7 can be set in stop sleeve 5 side, the pretightening force of yielding rubber 4 can be regulated by increase and decrease adjustment pad 7.
Upper housing or lower housing 8 can also connect an energy-storaging spring, and the other end of energy-storaging spring is connected with housing of electric tool.Move downward with processing device 11 and be processed as example, upper housing 1, lower housing 8 move downward compress energy storage spring and store energy, move upward to unclamp energy-storaging spring and release energy.
It is emphasized that above mode of execution to be only used to principle of the present invention is described and the illustrative embodiments that adopts, but invention is not limited thereto.For those skilled in the art, without departing from the spirit and substance in the present invention, can make various modification and improvement, these modification and improvement are also real is protection scope of the present invention.
