Abstract
The invention discloses an electric hammer which comprises a front end handle, a rear end handle, a gearbox and an impact lever. The front end handle is fixed to the impact lever, the rear end handle is connected with the gearbox, the upper end of the rear end handle is connected with the upper end of the gearbox through a regulating spring, the lower end of the rear end handle is connected with the lower end of the gearbox through an elastic assembly, a motor, a gear assembly and a connection rod are arranged in the gearbox, and the connection rod is arranged in a clamping head in a sleeved mode and is connected with the impact lever. Due to the spring and the elastic assembly arranged between the rear end handle and the gearbox, the situation that in the use process, high-torque reverse acting force produced by the stuck situation of a drill bit is transmitted to an operator can be avoided, a certain buffering function is achieved and safety of the operator is guaranteed.
Description
Technical field
The present invention relates to electric hammer, belong to field of power tools.
Background technology
Traditional electric hammer in use needs workmen to exert pressure and could produce impulsive force with hand, and reciprocating air in cylinder makes cylinder inner air pressure be cycle variation, the top that the air pressure of variation drives the hammer in cylinder back and forth to hit drill bit.The drill bit frequent impact of electric hammer, the power that operator is produced retreat, restive handle.Therefore, need to provide a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
For addressing the above problem, the invention provides a kind of convenient electric hammer of controlling.
The technical solution adopted for the present invention to solve the technical problems is:
Electric hammer, comprise front end handle, rear end handle, gear-box and impact bar, described front end handle is fixed on impact bar, described rear end handle is connected with gear-box, handle upper end, described rear end is connected with gear-box upper end by regulating spring, described rear end handle, at its lower end is connected with gear-box lower end by elastic parts, is provided with motor, gear assembly and connecting rod in described gear-box, and described connecting rod is placed in dop and is connected with impact bar.
Described motor shaft end cover has pinion, and described pinion engages with gear wheel, and described gear wheel is placed on eccentric shaft, and on described eccentric shaft, cover has eccentric wheel, and described eccentric wheel is connected by axle with connecting rod.
Described elastic parts is the rubber pneumatic bag of multiple-layer stacked.
Described front end handle is provided with rubber sleeve.
The invention has the beneficial effects as follows: the spring arranging between rear end handle and gear-box and elastic parts, can avoid the large torque reaction power that in use clamping stagnation because of drill bit produces to pass to operator, there is certain cushioning effect, ensure operator's safety.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Wherein: 1, front end handle, 2, rear end handle, 3, gear-box, 4, impact bar, 5, regulating spring, 6, motor, 7, connecting rod, 8, dop, 9, pinion, 10, gear wheel, 11, eccentric shaft, 12, eccentric wheel, 13, rubber pneumatic bag, 14, rubber sleeve.
Detailed description of the invention
As shown in Figure 1, electric hammer of the present invention, comprise front end handle 1, rear end handle 2, gear-box 3 and impact bar 4, front end handle 1 is fixed on impact bar 4, rear end handle 2 is connected with gear-box 3, handle 2 upper ends in rear end are connected with gear-box 3 upper ends by regulating spring 5, electric hammer in use, produce certain impulsive force, and spring 5 can slow down this impulsive force, people is held in and on rear end handle 2, can feel gruelling, handle 2 lower ends in rear end are connected with gear-box 3 lower ends by elastic parts, in gear-box 3, be provided with motor 6, gear assembly and connecting rod 7, connecting rod 7 is placed in dop 8 and is connected with impact bar 4.
Motor 6 axle head covers have pinion 9, and pinion 9 engages with gear wheel 10, and gear wheel 10 is placed on eccentric shaft 11, and on eccentric shaft 11, cover has eccentric wheel 12, and eccentric wheel 12 is connected by axle with connecting rod 7.Motor 6 rotates, gear engagement, and eccentric shaft 11 rotates band movable eccentric wheel 12 and rotates, and drivening rod 7 moves forward and backward, and impact bar 4 is also being followed and is being moved up and down, and produces impulsive force.
The rubber pneumatic bag 13 that above-mentioned said elastic parts is multiple-layer stacked.Further alleviate electric hammer and impact the recoil producing.
Reduce hand wearing and tearing, front end handle 1 is provided with rubber sleeve 14.
Electric hammer of the present invention, can avoid the large torque reaction power that in use clamping stagnation because of drill bit produces to pass to operator, has certain cushioning effect, ensures operator's safety.
