Description
Technical field
The utility model is related to a kind of 21V lithiums electricity big torque spanner of brush DC.
Background technology
Conventional spanner is non-adjustable due to outputting torsion, so the screw of different size needs to use different outputting torsions
It is many to tighten work what electric wrench realize screw or nut, inconvenience is so not only operated, and also use cost is also high.And
And instrument nut in work high above the ground is exited easily to be dropped when taking out completely and gets to following personnel, safety coefficient is low.
The content of the invention
For the drawbacks described above for overcoming existing spanner to exist, the utility model provides a kind of 21V lithiums electricity big torsion of brush DC
Torque wrench.
The technical solution adopted in the utility model is：
The 21V lithiums electricity big torque spanner of brush DC, including casing handle, middle cover, head capsule, electric machine assembly, impact rotation
Mechanism and T-shaped axle, described electric machine assembly are arranged in casing handle, described impact rotating mechanism be arranged in head capsule and by
Electric machine assembly drives, and one end of described T-shaped axle is connected with impact rotating mechanism, head capsule is stretched in outside the other end, its feature
It is：Described electric machine assembly includes the switch, electric machine controller, motor stator, rotor and the rotor that are connected with power supply
Tooth axle, described switch is connected with described electric machine controller, and described electric machine controller is connected with described motor stator, institute
The motor stator stated is connected with described rotor, and the end of described rotor is arranged with rotor pinion；
Described impact rotating mechanism includes impacting shaft, impact block, and described impacting shaft is connected with a planet tooth, described
Planet tooth is intermeshed with rotor pinion；Described impact block is set on described impacting shaft by gear ring, described impact
Axle is connected with T-shaped axle.
Operation principle of the present utility model：
Electric current flows into switch after energization, and electric current flows into electric machine controller after switch is opened, and electric machine controller sends electric signal
Motor stator field changes, and motor stator is rotated by the change drive motor rotor in magnetic field, rotor band
Dynamic rotor pinion rotates, and rotor pinion drives impacting shaft to rotate, and then impacting shaft drives impact block to do and impacts
Motion, impact block drives T-shaped axle to do and impact and rotary motion, T-shaped axle do ballistic motion drive outside workpiece make workpiece urgent or
Ease out.
The beneficial effects of the utility model are embodied in：
1. brushless, the long-life：Inside uses brushless electric machine, loses will not because of no carbon brush during use whole machine
Effect；
2. output torque is big, can tear automobile tire open；
3. there is withdrawing nut to unclamp automatic hold function.When the function is opened, instrument can be made when nut is dismantled by spiral shell
Mother is eased out without nut is exited completely.The function is by controller setting control.Specially motor is automatically stopped after moving back five circles：
It is mainly reflected in automatic detection nut to be totally released, then unclamps after being and move back motor automatic stop after five circles.Instrument is in high-altitude
Prevent nut from exiting to be dropped when taking out completely and get to following personnel during operation, make safety coefficient higher.
4. output torque is adjustable：It is adjustable that instrument is provided with two grades of output torques.
5. impacting shaft uses three gear transmission structures, and driving torque is bigger more steady.
