Abstract
The utility model discloses an electric-manual multifunctional wrench which comprises a driving device, a transmission device and a wrench socket device, wherein the driving device and the transmission device are arranged in a shell; the transmission device comprises a worm gear and a worm which are meshed with each other; the worm gear is connected with the wrench socket device; the worm is connected with the driving device that comprises a storage battery, a motor and a coupling; and the storage battery is connected with the motor, the output end of which is connected with the coupling, and the output end of the coupling is connected with the worm. The electric-manual multifunctional wrench adopts a worm gear-worm transmission way, has simple structure, is convenient to operate and reliable in design, and can easily realize primary electric tightening operation by taking the storage battery as a power supply for driving the motor; as the worm gear and the worm has self-locking performance, the worm gear, the worm and the motor can not rotate when manual operation is conducted, so that the wrench can also be used in power failure.
Description
Technical field
The utility model belongs to Wrench, be specifically related to a kind of current collection moving, manually in the multifunctional wrench of one.
Background technology
Prior art field, spanner have two kinds: manual wrench and electric wrench.Manual wrench, efficient is low when nutting, particularly when just tight.Electric wrench is divided into just two kinds of spanners and whole spanner again, and just tight electric wrench efficient when just tight is higher, when tight eventually, is difficult to reach the pretightning force requirement, and it is tight eventually also need to change instrument, and whole spanner then volume is bigger, and just tight efficient is extremely low.In addition, electric wrench can't use when having a power failure.
Summary of the invention
In order to overcome the problems referred to above that the prior art field exists, the purpose of this utility model is, provide a kind of electric hand two moving multifunctional wrench, simple in structure, easy to use, overcome in the prior art, the just tight and tight eventually problem that needs to change spanner of electric wrench, this device can be realized electronic just tight, can also realize simultaneously manually eventually tightly the use of also can meeting an urgent need during power failure.
The two moving multifunctional wrench of the electric hand that the utility model provides, it comprises drive unit, transmission device, wrench socket device, drive unit, transmission device are arranged in the housing, described transmission device comprises worm gear, worm screw, described worm gear is connected with worm engaging, worm gear connects the wrench socket device, and worm screw connects drive unit.Described worm screw two ends are provided with bearing, and bearing is installed in the bearing block, and bearing block is fixedlyed connected with housing.Described worm gear set is contained on the bearing, is provided with back shaft in the bearing, and back shaft is fixedlyed connected with housing.Described drive unit comprises battery, motor, shaft coupling, and battery connects motor, and the output of motor connects shaft coupling, and the output of shaft coupling connects worm screw.Described wrench socket device comprises sleeve, bearing, is detachable the connection between described sleeve and the bearing, and bearing is fixedlyed connected with worm gear, and perhaps bearing and worm gear are structure as a whole.Described housing also uses as handle simultaneously.
The two moving multifunctional wrench of the electric hand that the utility model provides, its beneficial effect is, this device adopts the kind of drive of worm and gear, simple in structure, easy to operate, reliable design are the power drives motor with the battery, can realize electronic just tight operation easily, because the self-locking property of worm and gear self, during manual operation, worm gear, worm screw, motor can not rotate, and can use when therefore having a power failure yet.

Mark among the figure:
1. bearing block; 2. shaft coupling; 3. motor; 4. battery; 5. housing; 6. worm gear; 7. worm screw; 8. bearing; 9. sleeve; 10. motor switch; 11. bearing; 12. back shaft.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the two moving multifunctional wrench of electric hand to the utility model provides are described in detail.
Embodiment
With reference to Fig. 1-Fig. 3, the two moving multifunctional wrench of the electric hand of present embodiment, it comprises drive unit, transmission device, wrench socket device, and drive unit, transmission device are arranged in the housing 5, and described housing 5 also uses as handle simultaneously.Described transmission device comprises worm gear 6, worm screw 7, and described worm gear 6 and worm screw 7 are connected with a joggle, and worm gear 6 connects the wrench socket device, and worm screw 7 connects drive unit.The two ends of described worm screw 7 are provided with bearing, and bearing is installed in the bearing block 1, and bearing block 1 is fixedlyed connected with housing 5.Described worm gear 6 is sleeved on the bearing 11, is provided with back shaft 12 in the bearing 11, and back shaft 12 is fixedlyed connected with housing 5.Described drive unit comprises battery 4, motor 3, shaft coupling 2, and battery 4 connects motor 3, and the output of motor 3 connects shaft coupling 2, and the output of shaft coupling 2 connects worm screw 7.Described wrench socket device comprises sleeve 9, bearing 8, is detachable the connection between described sleeve 9 and the bearing 8, and sleeve 9 has a plurality of different models, can change as required, realizes multi-function operation.Bearing 8 is fixedlyed connected with worm gear 6, and bearing 8 also can adopt integrative-structure with worm gear 6.
The circuit theory of its control section as shown in Figure 3, K switch is a master switch, only motor could be worked when K is closed; K switch can be in the corresponding motor M in 3 positions and be on 3 gears: contact A B engages with CD when just changeing, and contact A B is in shown position when stopping, and contact A B engages with EF during counter-rotating.
Charging plug is connected with the 220v AC power during charging, becomes direct current through alternating current behind the rectification circuit, promptly can be charge in batteries, and charging indicator light is bright during charging.
Hold handle during use, sleeve 9 is enclosed within on the nut or screw that needs loading and unloading, press motor switch 10 when needs are just tight, motor is delivered to wrench socket to torque by transmission system, just can turn nut or screw, when the electric power deficiency so that wrench socket when rotating, the circuit automatic disconnection, at this moment rotating spanner is manually tight eventually.Because the self-locking action of worm gear and worm screw, during manual operation, worm gear, worm screw, motor can not rotate.
