Abstract
The invention discloses an electric hammer. An eccentric protrusion block is arranged on a driving wheel to drive a hammer rod on an impact component, the hammer rod is enabled to overcome the acting force of a flexible element to axially deviate relative to a hammer head, and when a certain distance between the hammer rod and the hammer head is formed, the protrusion block is separated from the hammer rod to enable the hammer rod to quickly move toward the hammer head under the acting force of the flexible element and impact on the hammer head to realize hammering. The electric hammer is simple and compact in structure, portable and convenient for users to use and carry.

Detailed description of the invention
below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.
electric hammer shown in Figure 1, this electric hammer comprises the casing 1 with inner chamber, the driving wheel 3 be provided with motor 6 in the inner chamber of casing 1, being in transmission connection by transmission mechanism 2 with the output shaft of motor 6, casing 1 is also provided with the switch 7 obtaining electricity condition for controlling motor 6.Transmission mechanism 2 can be multiple reduction gearing, to meet the speed demand of driving wheel 3.
shown in Fig. 1 ~ 5, this electric hammer also comprises the impact assembly 5 be located on casing 1, and this impact assembly 5 comprises hammer cover 51, for the tup 52 of hammering and the hammer stem 53 for driving tup 52 to produce hammering.Hammer cover 51 is arranged in the inner chamber of casing 1 regularly, hammer cover 51 offers the through hole run through along its length, tup 52, hammer stem 53 can be located in above-mentioned through hole vertically slippingly, the axial line of tup 52, hammer stem 53 distributes along same rectilinear direction, and both axial lines are vertical with the axial line of driving wheel 3 arranges.The circumference of tup 52 has a flange 57, hammer cover 51 offers a groove 56, this groove 56 is connected with the through hole vestibule on hammer cover 51, and flange 57 can be housed in groove 56 along the axial slip of tup 52, can carry out spacing to the stroke of tup 52 slippage in through-holes like this.When arranging, annular flange flange can be set on the end of tup 52 towards hammer stem 53, accordingly, groove 56 is also set to annular groove, more convenient and the guiding that it can be provided good when tup 52 slippage of the processing of such tup 52, stroke when groove 56 is tup 52 hammering along the length of tup 52 axis.
shown in Fig. 1 ~ 5, the flexible member that hammer stem 53 elastic-restoring force vertically can be provided also is provided with in the inner chamber of casing 1, what adopt here is spring 55, spring 55 is set on hammer stem 53, one end of hammer cover 51 is provided with the first confined planes, hammer stem 53 having the second confined planes, conflicts respectively on the first confined planes and the second confined planes in the two ends of spring 55.Arranging the moment is set to ladder shaft-like by hammer stem 53, hammer stem 53 has large-diameter end and small axle diameter end, just the second confined planes is formed at large-diameter end and small axle diameter end, one end oral area and the small axle diameter end of hammering through hole on cover 53 into shape match, the small axle diameter end of hammer stem 53 is through this oral area, this end sidewalls of hammer cover 53 just forms the first confined planes, here, large-diameter end be housed in hammer cover 51 through hole vestibule in and be disposed adjacent with tup 52, small axle diameter end portion is housed in through hole vestibule, and spring 55 is set in small axle diameter end and is arranged in the part of through hole vestibule.
shown in Fig. 1 ~ 5, the end that hammer stem 53 passes hammer cover 51 through hole has a block 54, and this block 54 can be wholely set with hammer stem 53, is also fixedly connected on the above-mentioned end of hammer stem 53 by techniques such as welding.Driving wheel 3 is provided with a boss 4, the axial line of this boss 4 and the axial line of driving wheel 3 deviate, when driving wheel 3 rotates interval to certain position, boss 4 can be conflicted on block 54 and to promote block 3 and is moved, thus pull hammer stem 53 vertically and direction away from tup 52 is moved, and put outside interval when driving wheel 3 rotates supreme rheme, boss 4 is just separated with block 54.When arranging, boss 4 can be set to an eccentric wheel, eccentric axial line departs from the axial line of driving wheel 3 and is parallel to each other with the axial line of driving wheel 3, because eccentric circumference is arc surface, eccentric wheel and block 54 inconsistent and promote block 54 reposefully in process that is that rotate with driving wheel 3 and move ahead.
like this, this electric hammer in use, under original state, as shown in Figure 2, first tup 52 is aimed at the object treating hammering, tup 52 is pushed to annular flange flange 57 in annular groove 56 on the cell wall of hammer stem 53 under the effect of the pressure, and at this moment motor 6 task driven wheel 3 is rotated counterclockwise, and eccentric wheel 4 rotates around the axial line of driving wheel 3 thereupon; When eccentric wheel 4 rotates the position extremely as Fig. 3, eccentric wheel 4 is conflicted on block 54, along with the continuous rotation of driving wheel 3, eccentric wheel 4 promotes block 54 and the elastic acting force overcoming spring 55 moves vertically, and hammer stem 53 moves away from the direction of tup 52 thereupon vertically; When driving wheel 3 rotates to position as shown in Figure 4, hammer stem 53 reaches the limit of position, the distance that now the large-diameter end of hammer stem 53 is certain apart with tup 52; When driving wheel 3 continues to rotate, eccentric wheel 4 is just separated with block 54, at this moment the spring 55 compressed is released, under the effect of spring 55 elastic force, hammer stem 53 is vertically towards the direction movement fast of tup 52, hammer stem 53 strikes on tup 52 releases tup 52 fast, and the object end of tup 52 being impinged upon treat hammering forms the impact treating hammering object.This electric hammer is simple and compact for structure, and complete machine is light, makes user to use easily and to carry.
