Background technology
The motor of common electric impact drill, working head and drill bit promptly on the length direction of electric impact drill, need 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 realize, if tend to destroy the metope of having fitted up again or destroy indoor other object during firmly with common electric drill punching, said electric impact drill with 360 degree rotary work heads can address this problem easily.
Summary of the invention
In order to address the above problem; The present invention provides a kind of electric impact drill with 360 degree rotary work heads, adopts two pairs of bevel gears and pair of straight gear to carry out transmission, makes 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.
The scheme that the present invention adopted is:
Electric impact drill 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; Said transmission system mainly by the rotor axle, initiatively straight bevel gear, driven straight bevel gear, power transmission shaft I, damping spring I, initiatively corner spur gear, driven corner spur gear, initiatively 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; Said rotor axle is vertical each other with said power transmission shaft I; Said active straight bevel gear is installed on said rotor axle one end; Said driven straight bevel gear is installed on the lower end of said power transmission shaft I, said active straight bevel gear and said driven straight bevel gear engagement; Said active circular cone helical gear and said active corner spur gear are installed on the upper end of said power transmission shaft I successively; Said driven corner spur gear and said six are installed on the two ends of said power transmission shaft II with cam, and said power transmission shaft II and said power transmission shaft I are parallel to each other, and said active corner spur gear and said driven corner spur gear mesh; Said driven circular cone helical gear is installed on said output shaft, and said output shaft is vertical each other with said power transmission shaft II, said driven circular cone helical gear and the engagement of said active circular cone helical gear; Said needle roller is positioned at said output shaft one end and contacts with cam slide with said six.
The invention has the beneficial effects as follows:
Said electric impact drill structure with 360 degree rotary work heads rationally, working head can be rotated in punching in 360 ° of scopes, promptly 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 said 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.
Fig. 2 is said transmission system enlarged diagram.
Among the figure, 1. bonnet, 2. firm handle, 3. switch, 4. working head handle, 5. work head-shield; 6. transmission system outer cover, 7. protecgulum, 8. rotor axle, 9. fan, 10. straight bevel gear initiatively, 11. driven straight bevel gears; 12. power transmission shaft I, 13. damping spring I, 14. active corner spur gears, 15. driven corner spur gears, 16. active circular cone helical gears, 17. driven circular cone helical gears; 18. power transmission shaft II, 19. 6 and cam, 20. needle rollers, 21. damping spring II, 22. output shafts.
The specific embodiment
Like Fig. 1 is said electric impact drill schematic appearance with 360 degree rotary work heads, has (4) two handles of firm handle (2) and working head handle, make grip convenient firmly; When angle of needs conversion is carried out percussion action; Catch working head handle (4), go to required angle said driven corner spur gear (15) is rotated, through the drive connection that is mated; Can make working head produce corresponding rotation, reach the purpose of adjustment angle.
Like Fig. 2 is said transmission system enlarged diagram, mainly by rotor axle (8), initiatively straight bevel gear (10), driven straight bevel gear (11), power transmission shaft I (12), damping spring I (13), initiatively corner spur gear (14), driven corner spur gear (15), initiatively circular cone helical gear (16), driven circular cone helical gear (17), power transmission shaft II (18), six and cam (19), needle roller (20), damping spring II (21) and output shaft (22) are formed.Said rotor axle (8) is vertical each other with said power transmission shaft I (12); Said active straight bevel gear (10) is installed on said rotor axle one end; Said driven straight bevel gear (11) is installed on the lower end of said power transmission shaft I, said active straight bevel gear (10) and said driven straight bevel gear (11) engagement; Said active circular cone helical gear (16) and said active corner spur gear (14) are installed on the upper end of said power transmission shaft I successively; Said driven corner spur gear (15) is installed on the two ends of said power transmission shaft II (18) with said six with cam (19), and said power transmission shaft II and said power transmission shaft I are parallel to each other, and said active corner spur gear (14) and said driven corner spur gear (15) mesh; Said driven circular cone helical gear (17) is installed on said output shaft (22), and said output shaft is vertical each other with said power transmission shaft II, said driven circular cone helical gear (17) and said active circular cone helical gear (16) engagement; Said needle roller (20) be positioned at said output shaft one end and with said six and cam (19) sliding-contact.
