Handheld type ultrasonic electric drill

Abstract

The invention discloses a handheld type ultrasonic electric drill, which comprises a drill bit, an ultrasonic vibrator, an output shaft, a carbon brush, an insulated coupling, a motor, an outer casing, a power transmission cable, an electric drill controller, a motor rotation speed control trigger, an ultrasonic switch pushbutton, a fixing ring, an electric collector ring, an insulation ring and an ultrasonic power source, wherein the output end of the output shaft is connected with a flange disc of the ultrasonic vibrator, the drill bit is arranged at the output end of the ultrasonic vibrator, and the electric energy input end of the ultrasonic electric drill controller is electrically connected with the ultrasonic power source by the power transmission cable. The handheld type ultrasonic electric drill has the advantages that the ultrasonic vibration is realized, the ultrasonic vibration frequency reaches 20kHz, the drilling force in the drilling process is obviously reduced, an operator can use smaller force to drill material, the labor intensity of the operator is decreased, the drilling efficiency is improved, the abrasion of the drill bit is reduced, the drilling quality is high, the flashes and burrs are fewer, the damage to surrounding material is avoided, and the secondary processing on the surfaces with higher quality requirement is not needed.

Description

technical field [0001] The invention belongs to the field of electric tools, and in particular relates to a hand-held ultrasonic electric drill. Background technique [0002] The electric hand drill is one of the most versatile products among electric tools. Because of its simple operation, it is widely used in manufacturing, construction, home improvement and other industries for drilling operations on various materials. The basic principle is to use the high-speed rotation of the drill bit to remove material. When using a hand drill to drill holes in materials, the operator needs to hold the hand drill hard, especially when drilling high-hardness materials such as stone, concrete, stainless steel or titanium alloys, the operator needs to apply a large force, and it is easy to The hole is drilled crookedly. When using a hand electric drill to drill holes, the labor intensity of the operator is high, the drill bit wears out quickly, the drilling efficiency is low, and even...
