Lithium battery charging electronic torsion adjusting electric drill

Abstract

The invention discloses a lithium battery charging electronic torsion adjusting electric drill. The electric drill comprises a brushless motor, a lithium battery charging module connected with the brushless motor, a gear box and a drill bit clamp; and an output shaft of the brushless motor penetrates through the gear box to connect with the drill bit clamp. The electric drill further comprises a torsion adjusting mechanism arranged at the front end of the gear box for adjusting the torsion of the drill bit clamp; the brushless motor is connected with a brushless driver; the brushless driver is connected with an adjusting switch and a micro switch for controlling the brushless driver; the torsion adjusting mechanism is upwards rotated to a maximum torsion position in the axial direction to apply the pressure to the micro switch to realize electric connection with the brushless driver; and the brushless driver is controlled to output electronic torsion. The electric drill realizes two output modes of mechanical-electronic torsion; the electronic torsion realizes stepless linear outputting; the middle torsion cannot be continuously changed; and the electric drill is suitable for application places with requirements or precise requirements on the magnitude of fixed torsion.

Description

technical field [0001] The invention relates to the field, in particular to a lithium battery rechargeable electronic torque-adjusting electric drill. Background technique [0002] Existing lithium battery rechargeable electric drills generally adopt a mechanical single-mode torque adjustment scheme. The torque output is realized through the torsion spring, steel ball and planetary gearbox inside the gearbox. Generally, the setting is 1-18 or 1-24 or dry. stalls. Since the gears are intermittent, it is impossible to achieve stepless linear torque adjustment, and the torsion spring is affected by factors such as material technology, processing accuracy, assembly production, etc., resulting in the inability to maintain accurate and consistent torque between gears. Contents of the invention [0003] The purpose of the invention is to increase the torque adjustment and gear accuracy of the lithium battery rechargeable electric drill. [0004] In order to achieve the above ob...
