Abstract

The invention discloses a small self-energy-taking ultrasonic vibration electric spindle, and belongs to the field of vibration cutting. The traditional drilling manner is changed, and the irreplaceable advantages are achieved. The electric spindle comprises an amplitude-change rod, an end cover, piezoelectric ceramics, a circuit box, a first coil, a second coil, a cover shell, a stator, a rotor,an inner shaft and a magnet; the stator, the rotor and the inner shaft are arranged in the cover shell in sequence, the second coil is arranged at one end of the stator, the rotor is fixed to the inner shaft, multiple sets of magnets are arranged at one end of the inner shaft, the first coil is arranged outside the magnet, and pressing is achieved through the end cover; a circuit board connected with the magnet is arranged in the end cover, the end cover is connected with the piezoelectric ceramics through the circuit board, one end of the piezoelectric ceramics is fixed to the amplitude-change rod, and axial reciprocating motion is achieved; the other end of the amplitude-change rod is fixed to the inner shaft. Through the end cover, pressing and fixing to the cover shell are achieved. The electric spindle is small in size, small in whole mass and capable of reducing the influence of the spindle weight on the machining precision, equipment input cost and manual cost.

Description

technical field [0001] The invention belongs to the field of vibration cutting, in particular to a small self-capturing ultrasonic vibration electric spindle. Background technique [0002] Vibration cutting technology (UVAC) as a novel special processing method, its principle is to improve the cutting pulse cutting method by vibrating the tool (or workpiece) in an appropriate direction, a certain frequency and amplitude. When processing hard and brittle materials, through low-frequency or high-frequency vibration of the tool to remove material, enhance chip breaking ability, improve workpiece processing quality and processing efficiency; reduce average cutting force, increase tool holder rigidity, and extend tool durability. Ultrasonic vibration drilling has changed the traditional drilling method and has irreplaceable advantages in the processing of small holes and deep holes. Therefore, it is urgent to study the ultrasonic vibration electric spindle technology that combine...
