Preferably, the ultrasonic generator is connected with the ultrasonic transducer through a transmission lead, the ultrasonic transducer is connected with the ultrasonic horn through a bolt, a central threaded hole is formed in the ultrasonic horn, and the supporting pressure head is connected with the ultrasonic horn through threads.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
The utility model provides a follow rest with ultrasonic vibration device which characterized in that includes: the ultrasonic vibration device comprises a bottom plate 1 and a main body 2, wherein an ultrasonic vibration mechanism 3 is arranged on the main body 2, the ultrasonic vibration mechanism comprises a supporting seat 4, an ultrasonic transducer 5 and an adjusting mechanism 6 for controlling the movement of the ultrasonic transducer are movably arranged on the supporting seat 4, an ultrasonic amplitude transformer 7 is arranged on the ultrasonic transducer 5, one end of the ultrasonic amplitude transformer 7 is connected with a supporting pressure head 8, and the ultrasonic transducer 5 is connected with an ultrasonic generator 9.
Preferably, the supporting seat 4 is a hollow cylinder, the ultrasonic transducer 5 is arranged in the hollow structure of the supporting seat 4, and one end of the horn 7 extends out of the supporting seat 4. Because the unused space in the supporting seat 4 is too large, the ultrasonic transducer 5, the ultrasonic amplitude transformer 7 and the supporting pressure head 8 are arranged in the inner space, so that the space is effectively utilized, and the cost is saved.
Preferably, the adjusting mechanism 6 includes a spanner wheel 10 and a threaded column 11, the spanner wheel 10 is welded to the upper end of the threaded column 11, the ultrasonic transducer 5 is installed at the lower end of the threaded column 11, an upper end cover is arranged at the upper end of the supporting seat 4, and the threaded column 11 is in threaded connection with the upper end cover of the supporting seat 4. The adjusting mechanism 6 is in threaded connection with the supporting seat 3, so that the adjusting mechanism 6 and the ultrasonic transducer 5, the ultrasonic amplitude transformer 7 and the supporting pressure head 8 which are connected with the adjusting mechanism can move up and down.
Preferably, the ultrasonic generator 9 is connected with the ultrasonic transducer 5 through a transmission lead, the ultrasonic transducer 5 is connected with the ultrasonic horn 7 through a bolt, a central threaded hole is formed in the ultrasonic horn 7, and the supporting pressure head 8 is connected with the ultrasonic horn 7 through a thread. Because the vibration amplitude of the ultrasonic transducer 5 is too small, the amplitude can be amplified by the ultrasonic amplitude transformer 7, so that the workpiece 12 can be pushed to effectively vibrate, and the workpiece 12 and the turning tool 13 are periodically cut, thereby reducing the cutting force in the turning process.
Preferably, two sets of ultrasonic vibration mechanisms 3 are arranged on the main body 2, and the supporting pressure heads 8 of the two sets of ultrasonic vibration mechanisms 3 are perpendicular to each other and are located in the same plane. Since the processing effect of the multi-dimensional ultrasonic vibration is better than that of the one-dimensional ultrasonic vibration, the multi-dimensional ultrasonic vibration is adopted in the embodiment.
Preferably, the main body 2 is L-shaped, and the two sets of ultrasonic vibration mechanisms 3 are respectively located at two ends of the structure of the main body 2. Since the present embodiment employs multi-dimensional ultrasonic vibration, the body 2 employs an L-shaped structure to mount the ultrasonic vibration mechanism 3 from multiple angles.
The working method of the follower rest with the ultrasonic vibration device is characterized in that the follower rest is arranged on a processing device, the position of the supporting pressure head 8 is adjusted to be in contact with the surface of the workpiece 12, after the processing device is started, the supporting pressure head 8 applies ultrasonic vibration to the surface of the workpiece 12, and meanwhile, the follower rest moves synchronously along with the turning tool 13 of the processing device.
Preferably, two sets of ultrasonic vibration mechanisms 3 are arranged on the follow rest, the supporting pressure heads 8 of the two sets of ultrasonic vibration mechanisms 3 are perpendicular to each other and are positioned in the same plane, and the amplitudes and the frequencies of the two sets of ultrasonic vibration mechanisms 3 are the same. Since the follower rest of the present invention not only supports the workpiece 12 but also pushes the workpiece 12 to vibrate regularly, the amplitude and frequency of the ultrasonic vibration mechanisms 3 of the two sets are the same to maximize the amplitude of the workpiece 12.
The working principle is as follows: the ultrasonic generator 9 converts alternating current into an oscillating electric signal, the ultrasonic transducer 5 converts the oscillating electric signal into mechanical vibration, and because the vibration output by the ultrasonic transducer 5 is too small to meet the requirement, the vibration is transmitted to the supporting pressure head 8 after being amplified by the ultrasonic amplitude transformer 7, so that the vibration is applied to the surface area to be processed of the workpiece 12. In the feeding direction of the turning tool 13, the supporting pressure head 8 keeps a certain distance in front of the turning tool 13, and the follow rest moves simultaneously when the turning tool 13 is machined, so that the regular vibration effect of machining is ensured.
It should be understood that the above-described specific embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Obvious variations or modifications which are within the spirit of the invention are possible within the scope of the invention.
