Problems solved by technology
[0008] The above existing ultrasonic vibration turning methods all fixedly connect the horn and the turning tool bar (or turning tool) as a whole. The problem with this method is that when the turning parameters (such as linear speed, cutting depth, When the amount of feeding, etc.) changes, the load characteristics of turning will change, and the change of this load will directly affect the stability of ultrasonic energy output, and the unstable output of ultrasonic energy will directly affect the vibration of turning tool tip and affect the quality of turning ;Even, under the condition that the load is heavy, the cutting force on the turning tool is lar

Embodiment Construction
[0021] Such as image 3 Shown, the ultrasonic vibration turning method of the present invention and figure 1 and figure 2 The difference in the existing ultrasonic vibration turning technology given is that the horn and the cutter bar (or turning tool) were in a tight connection before, but in the present invention, the horn 2 is pushed against the turning tool 1, which is located at the turning position of the turning tool. On the position of the tool bar between the tool tip and the tool rest 4, the horn 2 is not fixedly connected to the turning tool 1, but only in contact. The horn 2 is connected to the transducer 3 to electrically connect the transducer to an external ultrasonic generator. During the turning process, a pressure is applied to the horn 2, and the pressure is applied to the horn 2. The pressure can be applied by a spring, a hydraulic mechanism or a pneumatic mechanism. The pressure acts on the tool bar of the turning tool 1 through the horn 2, so that the...

The invention relates to an ultrasonic prepositioned one-way vibrating turning method. One end of an amplitude-changing rod is acted on a cutter rod of a turning tool; an acting position of the amplitude-changing rod on the turning tool is between a turning tool nose and a tool rest for mounting the turning tool; the amplitude-changing rod and the cutter rod of the turning tool are not in fastening connection but in contact; the other end of the amplitude-changing rod is connected with an energy converter; the energy converter is electrically connected with an ultrasonic generator; a pressure is applied to the amplitude-changing rod; during a turning process, the amplitude-changing rod is in contact with the cutter rod of the turning tool all the time under the effect of the pressure; the ultrasonic generator is started and an electric oscillation signal is converted into an ultrasonic frequency mechanical vibration by the energy converter; after the ultrasonic frequency mechanical vibration of the energy converter is amplified by the amplitude-changing rod, the ultrasonic frequency mechanical vibration is transferred to the turning tool; no matter how the turning parameters change, the stable output of ultrasonic energy is not directly influenced; and due to the stable output of the ultrasonic energy, a stable vibrating force is obtained by the cutter rod of the turning tool and the vibrating stability and the vibrating turning effect of the turning tool nose are ensured.
Description
technical field [0001] The invention relates to a method for performing ultrasonic turning on a workpiece on a lathe, and belongs to the technical field of ultrasonic turning. Background technique [0002] Ultrasonic vibration turning refers to the turning of the turning tool along the cutting direction at the vibration frequency and small amplitude of the ultrasonic range of vibration frequency f=16-50KHz and amplitude a=10-25μm. Utilizing this kind of vibration cutting, ultra-precision machining can be realized on ordinary lathes, that is, roundness, cylindricity, flatness, parallelism, and straightness can all be close to zero error, and lathes can be used instead of grinding. The application of ultrasonic turning has the following advantages: 1. Reduced cutting force: Vibratory turning is a kind of pulse cutting from a microscopic point of view. The effective cutting time of the tool in one vibration cycle is extremely short, and most of the time in one vibration cycle. ...
