The utility model content:
Goal of the invention of the present utility model is to overcome the deficiency of above-mentioned prior art, and the free of contamination hand held, electric borehole of a kind of energy-saving and environmental protecting machine is provided.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of hand held, electric borehole machine comprises power set, reducing gear, clutch, drilling tool and handle, and described power set drive drilling tool work through reducing gear, and described power set adopt motor.
Described reducing gear is a level Four gear shift, it comprises one-level gear, secondary tooth axle, secondary gear, three grades of tooth axles, tertiary gear, level Four tooth axle and the level Four gears that are in transmission connection together, wherein, the output shaft of one-level gear and described motor is connected, and level Four gear and described drilling tool are connected.
Described secondary gear is enclosed within on described three grades of tooth axles outward and matched in clearance between the two, described clutch comprises the upper friction plate that axially is sleeved on described three grades of tooth axles, following friction plate, the friction plate top board, the friction plate lower platen, torsion spring, torsion spring pressing plate and hex nut, wherein, on, following friction plate be located at respectively secondary gear on, lower surface, friction plate top board and friction plate lower platen are pressed in respectively, on the following friction plate, lower surface, torsion spring one end and friction plate top board are replaced, the other end and torsion spring pressing plate are replaced, and hex nut is arranged on torsion spring pressing plate upper end.
Being spline between described upper and lower friction plate and the described three grades of tooth axles is connected.
Described drilling tool is provided with perpendicular to ground.
The utility model has following advantage with respect to prior art:
Because to change petrol power is motor-driven to borehole machine of the present utility model, thereby defectives such as the power consumption of effectively having avoided gasoline engine to exist is big, seriously polluted, not environmental protection, have advantages such as energy-saving and environmental protecting are pollution-free, be more suitable in modern city, manipulating.
Description of drawings:
Fig. 1 is the main apparent direction structural representation of the electronic borehole machine of the utility model.
Fig. 2 is the side-looking direction structure schematic diagram of the electronic borehole machine of the utility model.
Embodiment:
Referring to Fig. 1 and 2, according to the hand held, electric borehole machine that the utility model provides, adopt motor 1 as power set, it comprises motor 1, reducing gear 2, clutch 3, drilling tool 4 and handle 5, power set 1 drive drilling tool 4 work through reducing gear 2.Reducing gear 2 is a level Four gear shift, thereby has bigger output torque, it comprises the one-level gear 21 that is in transmission connection together, secondary tooth axle 22, secondary gear 23, three grades of tooth axles 24, tertiary gear 25, level Four tooth axle 26 and level Four gears 27, wherein, one-level gear 21 is connected with the output shaft 11 of motor 1, and level Four gear 27 is connected with drilling tool 4.
Described secondary gear 23 is outer to be enclosed within on three grades of tooth axles 24 and matched in clearance between the two, and clutch 3 comprises and axially is sleeved on three grades of upper friction plate 31, friction plate 32, friction plate top board 33, friction plate lower platen 34, torsion spring 35, torsion spring pressing plate 36 and hex nuts 37 down on the tooth axle 24.Wherein, for spline is connected, when therefore upper and lower friction plate 31,32 rotated, three grades of tooth axles 24 also rotated thereupon between upper and lower friction plate 31,32 and the three grades of tooth axles 24.Upper and lower friction plate 31,32 adopts heat-resisting and wear-resisting copper alloy made, and be located at the upper and lower surface of secondary gear 23 respectively, friction plate top board 33 and friction plate lower platen 34 are pressed in the upper and lower surface of upper and lower friction plate 31,32 respectively, torsion spring 35 1 ends and friction plate top board 33 are replaced, the other end and torsion spring pressing plate 36 are replaced, and hex nut 37 is arranged on torsion spring pressing plate 36 upper ends.
The operation principle of the utility model clutch 3 is: friction plate top board 33 and friction plate lower platen 34 are under the pressure effect of torsion spring 35, to go up, following friction plate 31,32 tightly be pressed in secondary gear 23 on, lower surface makes the three keep the face contact, when secondary gear 23 at motor 1, when the drive of one-level gear 21 and secondary tooth axle 22 is rotated down, secondary gear 23 is with last, following friction plate 31, the frictional force that produces owing to the face friction between 32 drives three grades of tooth axles 24 and also rotates thereupon, and successively through tertiary gear 25, level Four tooth axle 26 and level Four gear 27 drive drilling tool 4, thereby make the machine operate as normal.When drilling tool 4 is run into stick of tool or stifled boring in the borehole process, when if face friction between above-mentioned secondary gear 23 and the upper and lower friction plate 31,32 and the frictional force that produces can not overcome this stick of tool or stifled external force of boring, then promptly can occur skidding between secondary gear 23 and the upper and lower friction plate 31,32, three grades of tooth axles 24 also stop operating thereupon, and and then drilling tool 4 is also quit work, guarantee safe in utilization.
Described drilling tool 4 is provided with perpendicular to ground, can guarantee the convenience of operating like this.
The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
