Abstract
The utility model relates to an electric screw driver gear box, including case shell, toothholder, CAMS propeller, commutator and wholesale cephalostat, the toothholder sets up in case shell one end, and the planet tooth of be equipped with the motor in the toothholder, being connected with the motor power shaft transmission is organized and the ring gear, planet tooth group is evenly fixed on CAMS propeller, CAMS propeller drives the commutator rotation through the steel ball that sets up in CAMS propeller's surface, criticize that cephalostat one end is fixed to be set up on the commutator, the other end to extend in the case shell outside, criticize the cephalostat with still be equipped with the axle sleeve between the case shell, it can embolia batch head to criticize the cephalostat front end. The utility model discloses the electric screw driver gear box of scheme, high torsion can be applicable to the bottle opener of industrial grade, enlarges market segments, and is small, portable uses the place no requirement (NR), has the advantage that job stabilization nature and reliability are high, and processing, installation and overhaul easy, the reduction maintenance cost.
Description
Technical field
This utility model relates to a kind of gear-box, particularly relates to a kind of electric screw driver gear-box, belongs to electric screw driver technical field.
Background technology
The engine of some electric screw drivers occurred in the market uses high rotating speed, the motor of little torque；Big drive mechanism is have employed between engine and operating mechanism.On the whole, current electric screw driver, there is structure complicated, the cumulative error of kinematic chain increases, and the motor of electric screw driver is usually placed in the rear of casing, motor shaft or parallel longitudinal with shell, or it is longitudinally perpendicular with shell, result causes casing complex-shaped, and difficulty of processing is big, causes electric screw driver overall structure the compactest.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and this utility model provides a kind of electric screw driver gear-box, and volume is little, it is simple to carry, high torque, it is possible to be applicable to the bottle opener of technical grade, expands market scope.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of electric screw driver gear-box, including case shell, toothholder, cam pusher, diverter and screwdriver bit holder, described toothholder is arranged on case shell one end, the planet tooth group being connected with motor power through-drive built with motor at toothholder and gear ring；Described planet tooth group is uniformly fixed on cam pusher；Described cam pusher drives diverter to rotate by the steel ball being arranged in the outer surface of cam pusher；Described screwdriver bit holder one end is fixedly installed on diverter, and the other end extends to described case outer side, is additionally provided with axle sleeve between described screwdriver bit holder and described case shell；Screwdriver bit can be inserted in described screwdriver bit holder front end.
Improve further as this utility model, between described cam pusher and diverter, be additionally provided with back-moving spring.
Improve further as this utility model, between described cam pusher and diverter, have oblique track.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
The electric screw driver gear-box of this utility model scheme, high torsion, it is possible to be applicable to the bottle opener of technical grade, expand market scope, volume is little, it is simple to carry, field of employment no requirement (NR), there is job stability and the high advantage of reliability, and processing, install and overhaul easily, reduce maintenance cost.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of electric screw driver gear-box of the present utility model；
Wherein, 1, case shell；2, toothholder；3, cam pusher；4, diverter；5, screwdriver bit holder；6, motor power axle；7, planet tooth group；8, gear ring；9, steel ball；10, oblique track；11, back-moving spring；12, axle sleeve.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of electric screw driver gear-box as shown in Figure 1, including case shell 1, toothholder 2, cam pusher 3, diverter 4 and screwdriver bit holder 5, described toothholder 2 is arranged on case shell 1 one end, the planet tooth group 7 being in transmission connection built with motor and motor power axle 6 at toothholder 2 and gear ring 8；Described planet tooth group 7 is uniformly fixed on cam pusher 3；Described cam pusher 3 drives diverter 4 to rotate by the steel ball 9 being arranged in the outer surface of cam pusher 3；Described screwdriver bit holder 5 one end is fixedly installed on diverter 4, and the other end extends outside described case shell 1, is additionally provided with axle sleeve 12 between described screwdriver bit holder 5 and described case shell；Screwdriver bit can be inserted in described screwdriver bit holder 5 front end.
The torsion of motor passes to planet tooth by motor power axle 6, by train (3 planet teeth, one gear ring) effect make motor export rotating speed reduce, torsion increase, three planet teeth are connected by pin and uniform are fixed on cam pusher 3, now cam pusher 3 is rotated through two steel balls 9 and drives diverter rotation 4, diverter 4 realizes phoresying by the boss coordinated and blade with screwdriver bit holder 5, screwdriver bit can be inserted in screwdriver bit holder 5 front end, by this series of actions, screwdriver head is finally made to connect and lock screw.When coupling mechanism force reaches the upper limit of machine, screwdriver bit will stop operating with screwdriver bit holder 5, now driven by motor cam pusher 3 parts such as grade are still in work, because there being oblique track 10 between cam pusher 3 and diverter 5, so the opposite force of meeting acts between diverter 4 when screwdriver bit holder 5 stops, diverter 4 moves down along oblique track 10, finally disengage with screwdriver bit holder 5, when locking work and completing to stop work done, owing to the back-moving spring 11 between diverter 4 and cam pusher 3 acts on, diverter 4 is made to reset.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
