Description

[0001]
[Industrial application fields]
The present invention relates to an ultrasonic deburring device that removes burrs generated in a metal workpiece by rotation and ultrasonic vibration.
[0002]
[Prior art]
Conventionally, in order to remove burrs generated in metal workpieces, stones, abrasives and rust preventives are put in the barrel, and the barrel is mechanically rotated and removed, or water is put in the container. Furthermore, a metal work is put in, ultrasonic waves are radiated into the water, and burrs are removed by cavitation generated in the water.
[0003]
[Problems to be solved by the invention]
However, in such a deburring apparatus, since stones, abrasives, rust preventives and water are used, after removing the burrs on the metal workpiece, afterwards removing stones and the like adhering to the metal workpiece. If a process is required, and if mechanical rotational vibrations are used, stones and abrasives become consumables, and those that generate burrs by generating ultrasonic waves in water use water as the medium. There is a problem that the material of the metal workpiece is limited and the size of the burr is also limited.
[0004]
[Means for solving problems]
According to the present invention, a cylindrical body is mounted so as to be rotated by a rotary drive device, a plurality of piezoelectric vibrators are mounted on the side surface of the cylindrical body, and the vibration surface of the piezoelectric vibrator is protruded inside the cylindrical body. The metal workpiece placed in the cylindrical body is deburred by ultrasonic vibration and rotation.
[0005]
[Action]
According to the present invention, a metal work is put into a cylindrical body and a plurality of piezoelectric vibrators are mounted on the cylindrical body for rotation, or a rotating body mounted with a plurality of piezoelectric vibrators inserted into the cylindrical body is rotated. Thus, the ultrasonic vibration is transmitted to the metal workpiece to remove burrs attached to the metal workpiece due to fatigue failure.
[0006]
【Example】
FIG. 1 is a schematic plan view of an ultrasonic deburring apparatus according to an embodiment of the present invention, and FIG. 2 is a side sectional view of the apparatus of FIG. 1. A plurality of piezoelectric vibrators 2 are mounted on a side surface of a cylindrical body 1. The vibration surface 2 a of the piezoelectric vibrator 2 is mounted so as to protrude inside the cylindrical body 1, and the central shaft 3 fixed to the lower portion of the cylindrical body 1 is mounted so as to be rotated by a bearing 5 mounted on the housing 4. The central shaft 3 is rotationally driven by a driving device 6 such as a motor.
[0007]
In the ultrasonic deburring device of the present embodiment configured as described above, a slip is attached to the central axis 3 on the piezoelectric vibrator 2 by rotating the cylindrical body 1 with the driving device 6 by putting a metal workpiece in the cylindrical body 1. When an oscillation output is applied from the oscillator 9 via the rings 7 and 8 to vibrate the vibration surface 2a, the metal work is free of burrs attached to the metal work due to the rotation of the cylindrical body 1 and the ultrasonic vibration of the piezoelectric vibrator 2. It is removed by fatigue failure.
[0008]
This embodiment does not require stones or abrasives as in the conventional example, and does not require a medium such as water, so that there is an advantage that no post-treatment is required to remove the stones or abrasives and the medium. is there.
[0009]
FIG. 3 is a schematic side view of an ultrasonic deburring device according to another embodiment of the present invention. A cylindrical body 1 having a plurality of piezoelectric vibrators 2 having a vibration surface on the inside is provided with bearings 10 and 11 attached to both ends thereof. Thus, the gear 14 is configured to rotate within the housing 12, and the gear 14 engaged with the gear 13 provided around the cylindrical body 1 is configured to be rotated by the motor 15.
[0010]
Then, the metal workpiece conveyed to the cylindrical body 1 by the belt conveyor 16 is input from the input port 1 a at the upper part of the cylindrical body 1, the cylindrical body 1 rotates, and the belt conveyor 17 from the output port 1 b below the cylindrical body 1. Taken out on top.
[0011]
In this manner, when the cylindrical body 1 is rotated by providing the inlet 1a and the outlet 1b at the upper and lower portions of the cylindrical body 1 and the plurality of piezoelectric vibrators 2 are vibrated, the metal workpiece input by the cylindrical body 1 is cylindrical. While passing through the inside of the body 1, burrs attached by rotation of the cylindrical body 1 and ultrasonic vibration of the piezoelectric vibrator 2 can be completely removed.
[0012]
FIG. 4 is a schematic side view of an ultrasonic deburring device according to still another embodiment of the present invention. The vibration surface 2a of the piezoelectric vibrator 2 is mounted on the outer surface of the cylindrical body 1, and the cylindrical body 1 is attached to the container. 18, the central shaft 3 of the cylindrical body 1 is connected to the rotation shaft of the driving device 6, the central shaft 3 is rotatably supported by a bearing 19 provided on the support plate 20, and the driving device 6 is mounted on the cylindrical body 1. It is mounted on a plate 19 provided on the container 18.
[0013]
In the ultrasonic deburring device of this embodiment configured as described above, when a metal workpiece is put in the container 18, the cylindrical body 1 is rotated by the driving device 6, and the plurality of piezoelectric vibrators 2 are vibrated, the container 18. The metal workpiece put into the can completely remove burrs attached by the rotation of the cylindrical body 1 and the ultrasonic vibration of the piezoelectric vibrator 2.
[0014]
【The invention's effect】
As is clear from the above description, in the ultrasonic deburring device of the present invention, the cylindrical body is rotated, and the piezoelectric vibrator attached to the cylindrical body is ultrasonically vibrated, so that the burrs attached to the metal workpiece are removed.
