Two-way wave ultrasonic automatic tool change electric spindle

Abstract

The invention relates to a two-way wave ultrasonic automatic tool-changing electric spindle, which includes a main body of the electric spindle and a rotor shaft. The rotor shaft passes through the inner ring of the bearing to realize rotation. The vibrator and the radial vibrator are respectively sleeved on the outer end surface of the bearing. The axial vibrator and the radial vibrator are connected to the ultrasonic driver. The axial vibrator can excite the bearing in the axial direction, and the radial vibrator can vibrate the bearing in the radial direction. An elastic deformation pad is provided, and the two ends of the elastic deformation pad abut against the axial vibrator and the radial vibrator respectively. The present invention adopts the method of superimposing axial and radial vibrations to excite the rotary cutter head. According to the cutting effect, it can be at the same frequency and phase, or at the same frequency and different phases, or alternately vibrate, and finally make the rotor shaft vibrate in the axial direction. At the same time, it is also doing radial vibration, forming two-way vibration. The invention has the advantages of simple installation, firm structure, stable operation, and can cut axially and radially.

Description

technical field [0001] The invention relates to the technical field of electric spindles, in particular to a two-way wave ultrasonic automatic tool-changing electric spindle for cutting superhard materials. Background technique [0002] In the current high-end manufacturing, the cutting of superhard materials is a major problem. The main reason is that the electric spindles currently used for cutting are all high-speed rotating types, which makes it difficult to process superhard materials. [0003] The existing ultrasonic automatic tool-changing electric spindle, such as the ultrasonic automatic tool-changing electric spindle disclosed in Patent No. CN106112021B, adopts an axial vibration mode, which generates axial waves, and cannot process superhard materials. Contents of the invention [0004] As we all know, the cutting of superhard materials is a major problem in the processing industry. The present invention is mainly designed to solve the problem of cutting superha...
