Auxiliary pneumatic drill based on ultrasonic vibration

Abstract

The invention discloses an auxiliary pneumatic drill based on ultrasonic vibration. Due to the fact that the ultrasonic vibration is applied to a traditional pneumatic drill, a compound machining mode is formed by organic combination of the ultrasonic vibration and traditional drilling mechanical movement, the continuous cutting mechanism of traditional drilling machining is broken, and the good machining effect is achieved. An ultrasonic transducer is installed on a connecting outer cover through an ultrasonic variable-amplitude mechanism, and a drill bit clamping mechanism is fixedly installed at the front end of the ultrasonic variable-amplitude mechanism. Due to the fact that the ultrasonic vibration is used for assisting drilling, the cutting performance of difficult-to-machine materials is effectively improved, and application of drilling machining is wider. Discontinuous drilling machining of the ultrasonic vibration can solve the problem of poor accuracy, caused by accumulation of lead deviation, of the form and the position, and dimension accuracy of deep-hole machining is improved. Due to the fact that the ultrasonic vibration is used for assisting drilling, average drilling force is reduced, chip breaking and chip discharge are facilitated, abrasion of cutters is reduced, the situation of prolonging the service life of the cutters is facilitated, noise of drilling machining is effectively reduced, and the operation environment of workers is improved.

Description

technical field

[0001] The invention belongs to the technical field of ultrasonic vibration application, and in particular relates to an auxiliary air drill based on ultrasonic vibration. Background technique

[0002] Pneumatic drill is a hand-held pneumatic processing tool, mainly used for drilling metal components, especially suitable for drilling thin-walled shells and light alloy components such as aluminum and magnesium. Widely used in automobiles, ships, aviation, aerospace industry manufacturing and home appliance manufacturing industries. At present, the air drills mainly used are: pistol air drill, straight handle air drill, elbow air drill, countersunk air drill, and screw feed air drill. The advantages of the air drill are that it can accept continuous air signals, output linear displacement and angular displacement; high moving speed; high reliability; convenient maintenance and good adaptability to the environment; large output power and explosion-proof functio...
