Abstract
The utility model relates to an electric screwdriver, and particularly to a full-automatic brushless electric screwdriver. The structure comprises a housing which is internally provided with a motor. One end of a power output shaft of the motor is connected with a cutter head, and the other end is connected with one end of a circular switching assembly through a gear box body. The other end of the circular switching assembly is connected with a front end of a transmission shaft. The back end of the transmission shaft is connected with a hand-operated torque twister. A torque spring is provided outside the transmission shaft. A fixing assembly is provided outside the torque spring. A torque force adjustment sensor is provided between the torque spring and the fixing assembly. A U-shaped assembly is provided between the torque spring and the circular switching assembly. Steel balls are provided between the U-shaped assembly and the circular switching assembly. Compared with the prior art, the full-automatic brushless electric screwdriver of the utility model has the characteristics of reasonable design, simple structure, convenient operation, long service life, low manufacturing cost, etc.
Description
Technical field
The utility model relates to a kind of electric screw driver, and a kind of full-automatic brushless electric screwdriver specifically is provided.
Background technology
Traditional electric screw driver mainly comprises shell and places the interior motor of shell, the motor front end connects the transmission conversion equipment, driver bit is connected with screw terminal interface on the transmission conversion equipment, this electric screw driver is after switch activated, drive driver bit by motor through the transmission conversion equipment and rotate, behind screw tightening, need the manual operation 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, damaged screws die easily after screw is tightened, and, after screw is tightened braking,, influence the service life of screwdriver to bigger reverse impact power of motor formation of screw.
Summary of the invention
The utility model is at above deficiency, and a kind of reasonable in design, simple in structure, easy to operate, service life is of a specified duration, cost of manufacture is low full-automatic brushless electric screwdriver is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of full-automatic brushless electric screwdriver, comprise shell, be provided with motor in the described shell, power output shaft one end of described motor is connected with cutter head, the power output shaft other end of described motor connects an end of circular transition components by the gear-box main body, the other end of described circular transition components is connected with the front end of power transmission shaft, the rear end of described power transmission shaft connects the hand adjustment power twister, described power transmission shaft arranged outside has torque spring, described torque spring arranged outside has fixation kit, be provided with torsion between described torque spring and the fixation kit and regulate sensor, be provided with the U-shaped assembly between described torque spring and the circular transition components, be provided with hoodle between described U-shaped assembly and the circular transition components.
The rear end of power transmission shaft connects the hand adjustment power twister by the torsion set screw.
A kind of full-automatic brushless electric screwdriver of the present utility model does not in use have electromagnetic interference, is specially adapted to anti-electromagnetic interference processes, and it compared with prior art has following characteristics:
1, adopts the brushless drag cup motor of brand-new import.Can not produce high temperature in the use, carbon dust, performance is more superior, is particularly suitable for long-time continuous and uses, and has very strong durability, need not maintenance.
2, the internal gear assembly is that superior alloy steel directly is stamped to form, and noiselessness hangs down noise, and is noiseless.
3, the German advanced sensor signal system integration is adopted in torsion control, by semiconductor transducer control, has accurate torque value, and long-time use can keep precision, longer service life.
4, switch adopts the control of Hall magnetic induction switch, makes the switch longer service life.
5, up-to-date power supply design, it is big to break through traditional volume, and the shortcoming that power consumption is big is more apparent light and handy, convenient in the use, and is applicable to the working environment of 100-250V.
6, profile has incorporated the design of ergonomics, brings better comfort to the user, thereby has improved operating efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural representation of full-automatic brushless electric screwdriver.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of full-automatic brushless electric screwdriver, comprise shell, be provided with motor in the described shell, power output shaft one end of described motor is connected with cutter head, the power output shaft other end of described motor connects an end of circular transition components 2 by gear-box main body 1, the other end of described circular transition components 2 is connected with the front end of power transmission shaft 3, the rear end of described power transmission shaft 3 connects hand adjustment power twister 5 by torsion set screw 4, described power transmission shaft 3 arranged outside have torque spring 6, described torque spring 6 arranged outside have fixation kit 7, be provided with torsion between described torque spring 6 and the fixation kit 7 and regulate sensor 8, be provided with U-shaped assembly 9 between described torque spring 6 and the circular transition components 2, be provided with hoodle 10 between described U-shaped assembly 9 and the circular transition components 2.
Full-automatic brushless electric screwdriver of the present utility model in use, set the torsion maximum by hand adjustment power twister 5, when electric screw driver is worked, cutter head is at tighten the screws and then after making torsion arrive setting value, and hoodle 10 can become one and half states of throwing off, and spring 6 front portions can be to pressing down simultaneously, make it U-shaped assembly 9 to pressing down, regulate sensor 8 inductions with torsion, torsion is regulated sensor 8 signal of cutting off the electricity supply that reacts simultaneously, and actuation time is at 0.2-0.3 between second.Be designed to groove and externally threaded torsion set screw 4 matches at the terminal screw position of transferring torsion of screwdriver, tighten this torsion set screw 4 when mixing up torsion, having avoided in use, torsion changes.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
