- the present invention eliminates the need for measures such as soundproofing and the like by increasing the rigidity of the device on the processing tool side, and provides sufficient displacement and response speed to the object to be vibrated.
- the purpose is to be able to perform vibration processing well.
- the present invention provides a vibration device that vibrates a workpiece, and as the vibration device, first and second support members that support two opposite positions of the workpiece, A moving means for moving the support member on at least one side of the first and second support members between a support position and a disengagement position, and the workpiece is vibrated via the first and second support members.
- the first and second vibrators that can be applied and driving means for vibrating the first and second vibrators in opposite phases are provided.
- the first and second vibrators are vibrated through the supporting first and second support members. At this time, the first and second vibrators are vibrated in opposite phases, thereby amplifying the amplitude. Therefore, a sufficient amount of displacement can be given, and efficient machining can be performed while improving the tool life.
- the first support member or the second support member may be, for example, a clamp member that clamps two opposite positions of the workpiece or a center member that supports the center of the shaft-like workpiece.
- processing for example, cutting, grinding, drilling, or the like can be applied.
- the vibrator for example, an electrostrictive element or a magnetostrictive element is suitable.
- the first and second vibrators piezoelectric elements that generate vibration by expansion and contraction of a material are used. If the piezoelectric element is used in this way, the vibration generating mechanism can be easily configured with a light weight, and the responsiveness can be improved.
- the work piece is vibrated, and at this time, the first and second vibrators are reversed via first and second support members that support opposite portions of the work piece.
- the workpiece can be machined while amplifying the amplitude and giving a sufficient amount of displacement, and the tool life can be improved and efficient machining can be achieved.
- the responsiveness will be better, the tool life will be further improved, the machining efficiency will be improved, the generation of noise etc. can be suppressed, and the force can be reduced easily and lightly. Can be configured.

- FIG. 3 Comparison of displacement and response characteristics of various actuators that drive each transducer.
- FIG. 4 Explanatory drawing showing an example of applying this vibrator to drilling.
- FIG. 1 is an explanatory view showing an example in which the vibration exciter according to the present invention is applied to cylindrical grinding
- FIG. 2 is an explanatory view of a state before supporting a workpiece
- FIG. 3 is for vibrating a vibrator
- FIG. 4 is an explanatory diagram showing an example in which the vibration exciter is applied to drilling.
- the vibratory apparatus increases the rigidity of the apparatus on the processing tool side, performs a soundproofing treatment, etc. by processing while vibrating the workpiece itself when vibrating the workpiece.
- the outer surface of cylindrical workpiece W is ground. Has been applied.
- this grinding apparatus 1 includes a pair of left and right tailstocks 2 and 3 for supporting a cylindrical workpiece W, and a main body housing 5 of each tailstock 2 and 3. 1st, 1st arranged in Two support members 6a and 6b are provided, and the second support member 6b is movable forward and backward toward the first support member 6a side by a hydraulic cylinder 4 as a moving means.
- a center 7a7b that is rotatably supported by a bearing is provided at the tip of each supporting member 6a, 6b.
- the centers 7a, 7b are formed in the center holes c on both end surfaces of the cylindrical workpiece W. Engageable.
- a vibrator holding member 8 is provided on the base end side of the first and second support members 6a and 6b, and the base end side central portion of the first and second support members 6a and 6b is provided. Is provided with a plurality of substantially rectangular parallelepiped piezoelectric elements composed of piezoelectric material force such as ceramics, and the first support member 6a side has a first hole on the first support member 6a side.
- the second vibrator 11 is provided on the second support member 6b side. The piezoelectric element at the end of each of the vibrators 10 and 11 is held by the vibrator holding member 8.
- the driving means 12 for supplying electric energy to the first and second vibrators 10 and 11 is a sine wave (a non-inverted signal and an inverted signal that are 180 degrees out of phase with each other via a phase compensation circuit). ) To control the drive, amplify the amplitude in the axial direction, reduce the mass of the cylindrical workpiece W, and stabilize the deflection of the deflection. .
- a processing tool 13 such as a turret whose rotation is controlled by a control means can be brought into contact with the surface of the workpiece W.
- the state force shown in FIG. 2 is also driven after the second support member 6b advances and the center holes c at both ends of the cylindrical workpiece W are supported by both centers 7a and 7b. Due to the means 12 and phase compensation circuit, the piezo elements of the first and second vibrators 10 and 11 are 180 degrees out of phase.
- the drive control is performed to supply a sine wave signal
- the cylindrical work w starts to vibrate in the axial direction.
- cutting is performed with the relative slip that occurs only in the rotational direction, and the relative slip also occurs in the force axis direction, resulting in high-efficiency grinding.
- the load on the processing tool 13 is reduced, resulting in a longer tool life.
- the piezo element and the magnetostrictive element are excellent in response frequency and have a small amount of displacement! /.
- the practicality can be sufficiently secured by driving them in opposite phases.
- the mode of the force calorie taking the case of cylindrical grinding as an example of processing is not limited to this.
- the drilling force can be as shown in FIG. Ny can also be applied to other processes.
- both ends of the workpiece W are clamped by the first and second support members 6a and 6b, and at the same time, the first and second vibrators 10 and 11 are given anti-phase vibrations. Drill with drill 14.
- first and second vibrators 10 and 11 may be magnetostrictive elements instead of piezo elements.
