(57) [Abstract] [Objective] The present invention is a tool for ultrasonic machining, which is freely driven through a tool holder that uses ultrasonic vibration as a driving source, and the left and right ends of the tool tip are smoothly moved up and down without blurring. Get the work done. [Constitution] The present invention provides a tool holder with a plurality of holes,
By inserting a tool provided with a plurality of shanks corresponding to the plurality of holes into the tool holder, it is possible to prevent blurring occurring at the left and right ends of the tool tip when the tool is driven.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ultrasonic machining tool used in the field of engraving, engraving, cutting, and polishing on metal, stone, wood, synthetic resin, etc. The present invention relates to an ultrasonic machining tool having a structure in which it is inserted into a hole and an ultrasonic vibration is used as a drive source to freely drive the tool.

[0002]

[Prior art]

 Conventionally, a tool holder and a tool of this kind were newly devised and applied for, for example, the ultrasonic engraving / polishing machine developed by the present inventor in 1980 and sold by the present applicant since then. There is a tool holder and a tool of utility model (Registration No. 3002214). As shown in FIG. 5, this is a tool holder that is driven by using ultrasonic vibration as a drive source. One round hole d into which h can be inserted is provided, and the place where the tool g is driven freely through the tool holder c is placed on the opening end surface e of the tool holder c and abutted. In this case, in order to prevent the direction of the tool tip j from changing, the convex portion f is embedded in the round hole d of the tool holder c, and the shank h of the tool g is provided with the concave portion i to be combined.

[0003]

[Problems to be solved by the device]

 As in the prior art, when the tip of the tool g is small, a convex portion f embedded in the circular hole d of the tool holder c and a concave portion provided on the shank h of the tool g for determining the direction. A configuration in which i is combined is sufficient, and the slight slack required for driving has almost no effect on the work. However, when the tip of the tool is large, there is a problem that this slight loosening causes the left and right ends of the tool to rattle up and down, and smooth work cannot be obtained. The present invention has been made in view of the above problems of the conventional technology. The purpose of the present invention is to more reliably prevent the direction of the tool from changing when it is driven, and to prevent the tool tip from changing. For large objects, we are trying to provide a tool holder and a tool that allow smooth work without the left and right ends moving up and down.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems of the prior art, the ultrasonic machining tool according to the present invention is provided with a plurality of holes in the tool holder which is driven by ultrasonic vibration as a driving source. There is a structure in which a tool having a plurality of shanks positioned corresponding to the holes at a plurality of positions is inserted into the tool holder so that the tool comes into contact with the opening end face to perform free drive.

When the tool is brought into contact with the opening end surface of the tool holder to perform free drive, a slightly higher contact surface is provided at the center of the opening end surface to improve the contact effect. Good.

In order to prevent the ability of the shank of the tool to drive due to friction in the hole of the tool holder from decreasing, an appropriate component that reduces friction in the hole, such as a bearing or the like, is used as the tool. It is good to make and bury according to the shank.

[0007]

[Action]

 Since multiple shanks of the tool are inserted into the holes of the tool holder at multiple locations, the left and right ends of the tool tip do not move vertically when driving.

[0008]

【Example】

 An embodiment will be described below with reference to the accompanying drawings. The tool holder A shown in FIGS. 3 to 4 is made of a suitable material such as steel, and has a horn fastening screw 1 at the rear part as in the basic structure as in the conventional one. Two round holes 2'opened at both ends of the tip end face are provided in the axial direction of the central portion of the main body portion, while the main body of the tool B is made of a light material such as aluminum and is Two shanks 6 are provided at locations corresponding to the round holes 2'of the location. A diamond grindstone suitable for polishing the mold is fixed to the tool tip 7.

In order to improve the contact effect when the tool B is brought into contact with the opening end face 3 of the tool holder A to perform free driving, and to make uniform contact, the opening end face 3 of the opening end face 3 is formed. The contact surface 4 is provided at the center.

In order to prevent the shank 6 of the tool B from being deteriorated in the ability to be driven by friction in the round hole 2 ′ of the tool holder A, a hard synthetic resin that is resistant to friction in accordance with the shank 6 of the tool B is used. A pipe 5 made of metal is embedded, and a groove is formed on the inner wall of the pipe 5 for better sliding.

Since one embodiment of the present invention is configured as described above, a tool holder in which a tool is driven by using ultrasonic vibration as a drive source has a uniform contact on the opening end face. In addition, the two shanks of the tool slide sufficiently within the holes of the tool holder, so that the left and right ends of the diamond grindstone fixed to the tip of the driven tool shake up and down. Without touching the surface to be polished, to perform smooth and powerful work.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

The ultrasonic machining tool according to claim 1 is the same as the one described in detail in connection with the embodiment, wherein ultrasonic waves are generated by inserting a plurality of shanks of the tool into holes at a plurality of places of the tool holder. Use the vibration as a vibration source to bring it into contact with the opening end face, and drive it freely. The left and right ends of the tool tip do not move vertically and work smoothly.
