High-stability impact electric drill with stable and reliable impact function adjustment and impact method thereof

Abstract

The invention discloses a high-stability impact electric drill with stable and reliable impact function adjustment. The high-stability impact electric drill comprises a shell, an operation handle, anauxiliary handle, a driving motor, a gear speed reducing mechanism, an impact device, an impact function switch, an output shaft and a drill chuck; the drill chuck is mounted at the front end of the output shaft; the output shaft is connected with a motor rotating shaft of the driving motor through the gear speed reducing mechanism; the gear speed reducing mechanism comprises a large gear mountedon the output shaft, and a small gear mounted on the motor rotating shaft; the large gear is engaged with the small gear; the large gear is in interference fit with the output shaft; the small gear and the motor rotating shaft are integrally molded; an impact baffle plate is fixed on the impact function switch; and the position of the impact baffle plate is corresponding to the position of the impact device. The high-stability impact electric drill is simple in impact structure, convenient to operate, high in impact stability, high in impact feeling, comfortable in use hand feel, stable and reliable in gear assembly, high in punching stability, long in service life of the motor, low in cost and higher in quality, and relieves the labor intensity of users.

Description

technical field [0001] The invention relates to an electric tool, in particular to a high-stability impact electric drill with stable and reliable impact function adjustment and an impact method thereof. Background technique [0002] The impact drill is a multifunctional tool for screwing and drilling. The impact electric drill generally includes a drive motor, a gear reduction mechanism, an impact device, an impact function switch and a drill chuck. The impact electric drill drives the gear transmission through the drive motor, and through the gear deceleration, the output speed is reduced to a convenient range, and the output torque is increased to drive the drill chuck to rotate. The drill bit fixed on the drill chuck also rotates together, so as to realize the operation of drilling holes or tightening screws. [0003] There are many AC impact electric drills on the market now, the impact structure is more complicated, the operation is inconvenient, and the impact stabi...

AI Technical Summary

Problems solved by technology

[0003] There are many AC impact electric drills on the market now, the impact structure is more complicated, the operation is inconvenient, and the impact stability cannot be guaranteed, the impact feeling is very weak, the drilling efficiency is very low, and the drilling stability cannot be guaranteed, resulting in the motor The service life is not long, and the motor needs to be replaced frequently, which increases the labor intensity of workers and increases the cost of use
