A two-dimensional ultrasonic vibration assisted processing platform comprises a vibration table, a dynamometer, a first bracket, a second bracket, a first ultrasonic vibrator and a second ultrasonic vibrator; the first bracket is provided with the first ultrasonic vibrator, and an amplitude transformer of the first ultrasonic vibrator is connected with a rotary table of the vibration table; the upper surface of the vibration table is provided with the dynamometer by bolts, and the first bracket and the second bracket are arranged at 90 DEG; and the second bracket is provided with the second ultrasonic vibrator, and an amplitude transformer of the second ultrasonic vibrator is connected with a vibration worktable of the vibration table. According to the assisted processing platform, two groups of ultrasonic vibrators are applied to the rotary table and a vibration platform at a certain angle separately, and the vibration track of the processing platform can be regulated through the included angle between the two groups of the ultrasonic vibrators and the phase difference between two signals of ultrasonic generators, so that two-dimensional ultrasonic assisted processing for hard and brittle materials is achieved under the condition that modification of a main shaft of a machine tool is avoided; and the processing efficiency and surface quality of the processing platform are improved, and the tool wear is reduced.
Description
technical field [0001] The invention belongs to the technical field of ultrasonic auxiliary cutting processing in special processing technology, and particularly relates to a two-dimensional ultrasonic vibration auxiliary processing platform. Background technique [0002] In recent years, ultrasonic-assisted machining has been widely used in turning, milling, grinding, drilling of hard and brittle materials and non-metallic materials because of its advantages of effectively reducing cutting force, reducing cutting heat, improving workpiece surface quality, and increasing tool life. It has been widely used and paid attention to by scholars. [0003] At present, the industrial application of ultrasonic-assisted machining is mainly based on one-dimensional spindle vibration, and two-dimensional spindle vibration has also been widely studied. However, the application of vibration to the machine tool spindle requires the transformation of the machine tool spindle, and the resear...
