Integrated ultrasonic spindle motor vibration system for industrial robot machining

Abstract

An integrated ultrasonic spindle motor vibration system for industrial robot machining comprises a motor shell, and a spindle of a motor is a three-section composite amplitude-change pole; the composite amplitude-change pole sequentially comprises a small cylindrical section, a conical section and a large cylindrical section from front to back, and the front end of the small cylindrical section extends out of the front end face of the motor shell; the outer circle of the large cylindrical section is rotatably connected with the inner wall of the motor shell, and a motor rotor is arranged on the outer circle of the large cylindrical section; a piezoelectric ceramic stack is coaxially arranged on the rear end face of the large cylindrical section, and a front wireless transmission disc is coaxially arranged on the rear end face of the piezoelectric ceramic stack; a rear wireless transmission disc parallel with the front wireless transmission disc is arranged at the rear end of the motor shell; and the rear wireless transmission disc is connected with a wire. According to the integrated ultrasonic spindle motor vibration system, on the basis of ensuring that an original piezoelectric ceramic stack is not changed, namely under the condition that the power of an original transducer is not influenced, the overall size of the amplitude transformer is obviously reduced, and the use requirement of a tool changer at the tail end of the industrial robot can be met.

Description

technical field [0001] The invention belongs to the field of ultrasonic cutting processing and application of industrial robots, and in particular relates to an integrated ultrasonic spindle motor vibration system for industrial robot processing. Background technique [0002] In the traditional ultrasonic vibration system used for cutting processing, piezoelectric transducers, horns, wireless transmission units, etc. are designed around the spindle motor, and the ultrasonic components are assembled with the spindle motor to complete the ultrasonic machining vibration system.
