Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described further.
Manual, electric dual-purpose screwdriver of the present utility model, as Figure 1-3, it comprises:
Handle 01, it has tubular intracavity;
Power supply module 02, its removable tubular intracavity being arranged in handle 01, preferably one group is arranged on No. 7 or No. 5 dry cells 21 on battery carrier 22;
The motor 03 be electrically connected with power supply module 02, it is arranged in the inner chamber of handle 01 and is positioned at the front side of power supply module 02;
For the rotation of motor 03 being exported the mechanical reduction gear 04 slowed down, it is arranged in the inner chamber of handle 01 and is positioned at the front side of motor 03;
With batch bar 05 of screwdriver bit 51, screwdriver bit 51 can directly be made on batch bar, also can be removable, and batch bar 05 rear end is arranged in the inner chamber of handle 01 and is in transmission connection with mechanical reduction gear 04, and handle is stretched out in batch bar 05 front end;
For controlling the switch 06 that motor 03 works, it has the manipulation portion 61 being positioned at handle appearance, known, and this switch 06 is connected to for connecting circuit or disconnecting circuit on the circuit between power supply module 02 and motor 03, and is disconnected by circuit under normality;
Slow down through mechanical reduction gear 04 when motor 03 rotates and the torque of motor exported to batch bar 05 and realize electronic mode of operation; By the self-locking of mechanical reduction gear 04, batch bar is exported in the torque of handle when motor does not rotate and realize manual work pattern.During electronic mode of operation, hold handle, need not turning handle, the rotation according to motor can realize screwing; During manual work pattern, hold handle and rotate, the torque of handle is exported to batch bar and is realized screwing by the self-locking by mechanical reduction gear.
In order to make compact conformation, in smaller size smaller, realize larger step-down ratio and realize larger output torque, mechanical reduction gear 04 comprises at least two-stage gear reduction 41(and is illustrated as 3 grades); Every one-level gear reduction 41 comprises central gear 411, planetary gear 412 and ring gear 413, and planetary gear 412 to be assemblied on a tooth rest 414 and between central gear 411 and ring gear 413; The central gear of first order gear reduction is assemblied on the output shaft of motor 03; The central gear of next stage gear reduction is positioned on the tooth rest of upper level gear reduction, and the tooth rest of afterbody is connected with the rear-end transmission of batch bar 05.Thus, larger step-down ratio and larger output torque is achieved from the central gear of first order gear reduction to the tooth rest of afterbody gear reduction; Otherwise, from the tooth rest of afterbody gear reduction to the central gear of first order gear reduction, there is larger speed increasing ratio, self-locking can be realized according to this speed increasing ratio, therefore when manual work pattern, hold handle to rotate, the reaction force coming from screwdriver bit can not impel this mechanical reduction gear speedup rotate and the rotation of handle be converted to the passive rotation of motor.
During concrete enforcement, ring gear 413 can be positioned at the inner surface of handle 01, and illustrate this inner surface and be positioned on the leading portion handle body 13 hereafter addressed, ring gear also can be an individual components being fixed on handle.
In order to realize mechanical reduction gear and the transmission criticizing bar, the tooth rest of afterbody has axially extended moment of torsion run-out key 415 forward, the rear end of criticizing bar 05 has axially extended moment of torsion enter key 52 backward, together with moment of torsion run-out key 415 and moment of torsion enter key 52 are staggered at axial overlap.In order to avoid wearing and tearing, make uniform force, moment of torsion run-out key 415 and moment of torsion enter key 52 have gap 07 in circumference, and gap 07 is built-in with cylindrical rollers 08.
Handle 01 comprises one and is enclosed within the axle sleeve 11 criticized on bar 05, and for carrying batch bar, avoid batch bar to rock, batch bar 05 has the blocking surface 53 be positioned at bottom moment of torsion enter key 52, and roller 08 is constrained between axle sleeve 11 and blocking surface 53 and can not departs from from its operating position.Loosening in order to avoid assembling, when injection moulding leading portion handle body, axle sleeve can be embedded.
For the ease of assembling, handle 01 comprises the back segment handle body 12, the leading portion handle body 13 that are assembled together, and the rear end of back segment handle body 12 has tail-hood 14, and power supply module 02, motor 03 are positioned at back segment handle body 12.So, power supply module 02 is common can be loaded from the rear end of back segment handle body 12 or take out, and motor 03 then can front loaded from back segment handle body 12.For making back segment handle body, leading portion handle body is integrally formed and bears consistent moment of torsion, and back segment handle body, leading portion handle body are docking together by the keyway arrangements 15 being located at the two end.In order to avoid back segment handle body, leading portion handle body are axially thrown off, back segment handle body, leading portion handle body connect through horizontal bearing pin 16 or are connected together each other.For the ease of operation, switch 06 is for being assemblied in the push switch on leading portion handle body 13, and the outside cover of leading portion handle body 13 has flexible jacket 17, and manipulation portion 61 is located on flexible jacket 17, can manipulate this switch by pressing outside flexible jacket.
In view of the tubular intracavity of handle, the front end of motor 03 is fixed with mount pad 31 by securing member (as screw), mount pad 31 is assemblied in the inner chamber of handle by horizontal bearing pin, as shown in the figure, this horizontal bearing pin shares (but also can be independent) with the horizontal bearing pin 16 of the connection back segment handle body addressed, leading portion handle body above, during assembling, first motor 03, mount pad 31 can be placed in back segment handle body 12, more horizontal bearing pin 16 is horizontally through the through hole back segment handle body 12, mount pad 31 from the outside of back segment handle body 12.
In order to avoid batch bar axial float, criticize bar 05 spacing on handle with cover shaft block ring 55 in the middle by the large footpath section 54 of its afterbody, concrete, the spacing two ends at axle sleeve 11, handle 01 has protecgulum 18, shaft block ring 55 is positioned at the inner side of protecgulum 18, in order to avoid shaft block ring 55 weares and teares axle sleeve 11, is provided with packing ring 19 between shaft block ring 55 and axle sleeve 11.
Can Double-directional rotary in order to criticize bar when realizing electronic mode of operation, the inner chamber of handle 01 is provided with forward and reverse change-over switch 09, this forward and reverse change-over switch can be connected on the circuit between power supply module 02 and motor 03, the appearance of handle 01 is provided with the toggle control 91 for switching forward and reverse change-over switch, toggle control 91 is positioned at position orders about batch bar by motor rotate clockwise season, toggle control 91 is positioned at another position orders about batch bar by motor rotate counterclockwise season, no matter which position is toggle control be positioned at, and all do not affect manual work pattern.
