Description
Technical field
The utility model relates to a kind of electric screw driver.
Background technology
Traditional electric screw driver mainly comprises handle and places motor in the handle, and the motor front end connects the transmission conversion equipment, and driver bit is connected with screw terminal interface on the transmission conversion equipment.This electric screw driver drives driver bit by motor through the transmission conversion equipment and rotates behind switch connection, after screw is tightened, need manual operation to close switch, otherwise the rotation that driver bit will not stop down.The defective of this electric screw driver is to be difficult to control the tightness of screw, meeting repeated stock screw terminal after screw is tightened, damaged screws riveting easily; And, after screw is tightened braking,, influence the service life of screwdriver to bigger reverse impact power of motor formation of screwdriver.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, easy to operate at the defective of existing electric screw driver, can be tightened the back at screw and cut off motor power, the full-automatic screwdriver that it is stopped operating automatically.
The technical solution of the utility model is as follows: full-automatic screwdriver comprises the motor that is arranged on the screwdriver body interior, motor is connected with the output planetary frame of transmission conversion equipment, the output planetary frame is provided with planetary gearsets, planetary gearsets is provided with the internal tooth assembly outward, interior tooth assembly front end is connected with press spring base, press spring base holds out against the location by stage clip, the output planetary frame is by output sleeve connecting screw cutter interface, wherein, on the button limit of screwdriver rotating switch a magnet is set, be provided with power transmission shaft in button one side, the transmission the tip of the axis be provided with one can with the switch knob magnet of adhesive mutually, power transmission shaft is through 90 ° of fixed axis turnovers, its other end is connected with a spring that is fixed on the screwdriver body interior, spring connects an end of axis of traction, and the other end of axis of traction is connected by the press spring base of transverse arm with the transmission conversion equipment.
The utility model can drive the power transmission shaft of automatic power cutoff mechanism owing to the rotation of press spring base after screw tightening puts in place, make it to compress the turn knob of rotating switch, cuts off the electricity supply automatically, and driver bit is stopped operating.The utility model can be avoided the excessive infringement that screw and motor are caused of driver bit outputting torsion speed, and is rational in infrastructure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of the automatic power cutoff mechanism of the utility model.
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model transmission conversion equipment.
Among the figure, 1. tooth assembly 19. press spring bases 20. stage clips in the spring 2. rotating switches 3. magnet 4. shift knobs 5. magnet 6. axis of traction 7. transverse arms 8. screwdriver interfaces 9. fixed axis 10. power transmission shafts 11. motors 12. transmission conversion equipments 13. switch knobs 14. fixing holes 15. tie points 16. planetary gearsets 17. output planetary framves 18.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is specifically described.
Full-automatic screwdriver has all architectural features of traditional semi-automatic screwdriver, comprising the motor 11 that is arranged on the screwdriver body interior, motor 11 is connected with the output planetary frame 17 of transmission conversion equipment 12, as shown in Figure 2, output planetary frame 17 is provided with planetary gearsets 16, is provided with internal tooth assembly 18 outside the planetary gearsets 16, and interior tooth assembly 18 front ends are connected with press spring base 19, press spring base 19 holds out against the location by stage clip 20, and output planetary frame 17 is by output sleeve connecting screw cutter interface.When screwdriver ran well, output planetary frame 17 drove driver bit and rotates, and this moment, planetary gearsets 16 was rotated in interior tooth assembly 18, and interior tooth assembly 18 and press spring base 19 keep static owing to the pressure that is subjected to stage clip 20 holds out against; After screw tightening puts in place, driver bit is braked suddenly, at this moment, output planetary frame 17 still rotates, but because outside output braking suddenly, output planetary frame 17 can will be bigger power be applied to by planetary gearsets 16 on the tooth assembly 18, thereby tooth assembly 18 and press spring base 19 have overcome the frictional force that holds out against of stage clip 20 in causing, and rotate.
The utility model innovation part structurally is, button 4 limits at screwdriver rotating switch 2 are provided with a magnet 3, be provided with power transmission shaft 10 in button 4 one sides, the end of power transmission shaft 10 be provided with one can with switch knob 13 magnet 5 of adhesive mutually, power transmission shaft 10 is through 90 ° of fixed axis 9 turnovers, its other end is connected with a spring 1 that is fixed on the screwdriver body interior, and spring 1 connects an end of axis of traction 6, and the other end of axis of traction 6 is connected with the press spring base 19 of transmission conversion equipment 12 by transverse arm 7.
Because after screw tightening put in place, press spring base 19 can rotate suddenly, thereby drive axis of traction 6 extension springs 1, thereby power transmission shaft 10 rotates along fixed axis 9, is attracted by magnet 3, the button 4 that compresses switch downwards makes power remove, and motor 11 stops operating.When needs restart motor, press switch knob 13, the magnet of power transmission shaft 10 ends and switch knob adhesive mutually, thus make power transmission shaft break away from shift knob 4, power connection, motor 11 start immediately.
The utility model is rational in infrastructure, and cost is low, and is simple to operate, easy to maintenance, and long-term use is not fragile.
