Technical field
The present invention relates to electric tool, particularly a kind ofly construct rationally, can adapt to the electric impact drill with 360 degree rotary work heads that punches under small space and the particular surroundings.
Background technology
The motor of common electric impact drill, working head and drill bit namely on the length direction of electric impact drill, need have the space that can hold the length direction size of electric impact drill own at least, otherwise can not punch on same straight line during work.In the middle of the house of building trade finishing, need be to some specific position punchings, such as boring a hole obliquely in the top corner of a metope, common electric drill cannot be realized, if tend to destroy the metope of having fitted up again or destroy indoor other object when punching with common electric drill firmly, described electric impact drills with 360 degree rotary work heads can address this problem easily.
Summary of the invention
In order to address the above problem, the invention provides a kind of electric impact drill with 360 degree rotary work heads, adopt two pairs of bevel gears and pair of straight gear to carry out transmission, make working head to rotate, can precision offset the punching angle, it is easy to carry to become rugosity to make again in the working head rotation; Adopt cam to impact simultaneously, rather than the used impact teeth of common electric impact drill, the constant and more reasonable structure of motion.
Scheme of the present invention is:
Has the electric impact drill of 360 degree rotary work heads mainly by bonnet, firm handle, switch, the working head handle, the work head-shield, the transmission system outer cover, protecgulum and transmission system are formed, described transmission system is mainly by the rotor axle, the active straight bevel gear, driven straight bevel gear, power transmission shaft I, damping spring I, active corner spur gear, driven corner spur gear, active circular cone helical gear, driven circular cone helical gear, power transmission shaft II, six and cam, needle roller, damping spring II and output shaft are formed, described rotor axle is vertical mutually with described power transmission shaft I, described active straight bevel gear is installed on described rotor axle one end, described driven straight bevel gear is installed on the lower end of described power transmission shaft I, described active straight bevel gear and described driven straight bevel gear engagement; Described active circular cone helical gear and described active corner spur gear are installed on the upper end of described power transmission shaft I successively; Described driven corner spur gear and described six and cam are installed on the two ends of described power transmission shaft II, and described power transmission shaft II and described power transmission shaft I are parallel to each other, and described active corner spur gear and described driven corner spur gear mesh; Described driven circular cone helical gear is installed on described output shaft, and described output shaft is vertical mutually with described power transmission shaft II, described driven circular cone helical gear and the engagement of described active circular cone helical gear; Described needle roller is positioned at described output shaft one end and contacts with cam slide with described six.
The invention has the beneficial effects as follows:
Described electric impact drills structure with 360 degree rotary work heads rationally, working head can be rotated in punching in 360 ° of scopes, i.e. comprehensive can both the punching, and make that the punching angle is more accurate; Impact body adopts cam more shock-resistant, working head can fold make easy to carry.
Description of drawings
Further specify below in conjunction with figure of the present invention:
Fig. 1 is described electric impact drill schematic appearance with 360 degree rotary work heads, mainly is made up of bonnet, firm handle, switch, working head handle, work head-shield, transmission system outer cover, protecgulum and transmission system.
