Abstract

(57) [Summary] [Objective] The present invention aims to provide an excellent tool receiver capable of performing accurate cutting work. [Structure] When a tool 3 is mounted on a shank 5 provided on a spindle 2 by using a chuck device 1, a base end surface 3a of the tool 3 is in contact with the shank 5, and the shank 5 can be moved back and forth in the axial direction of the shank. The tool contact portion of the tip end surface is configured to be swingable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tool receiver arranged in a shank provided on a spindle.

[0002]

[Prior art]

 An appropriate tool 3 is press-fitted by a chuck device 1 to a shank 5 which is conventionally fitted to a spindle 2 of a cutting machine (the same components as those in this embodiment are designated by the same reference numerals).

When mounting the tool 3 on the shank 5, it is necessary to make the degree of protrusion of the tool 3 from the shank 5 appropriate. Therefore, the tip of the tool 3 is flat inside the female screw hole 5 a. The male screw body 4 formed in the above is screwed.

Therefore, the male screw body 4 is appropriately screwed into and out of the female screw hole 5a, and the base end surface 3a of the tool 3 is brought into contact with the flat end surface of the male screw body 4 to obtain an appropriate protrusion degree of the tool 3. ing .

[0005]

[Problems to be solved by the device]

 However, when the accuracy of the base end face 3a of the tool 3 is poor and the base end face 3a is an inclined surface, the tip of the male screw body 4 is a flat surface, so when the tool 3 is clamped by the chuck device 1, it is inevitable. Therefore, the tool 3 is not accurately mounted in the shank axis direction of the shank 5, so that the tool 3 naturally shakes during the operation of the cutting machine.

The present invention has a technical object to provide a tool receiver that solves the above problems.

[0007]

Means for Solving the Problems The gist of the present invention will be described with reference to the accompanying drawings.

When the tool 3 is mounted on the shank 5 provided on the spindle 2 by using the chuck device 1, the base end surface 3 a of the tool 3 comes into contact with the shank 5, and the shank 5 advances and retracts in the shank axis direction. A tool receiving body, wherein the tool contact portion of the tip end surface is configured to be swingable.

[0009]

[Action]

 Since the tool contact portion swings, the tool 3 can be accurately mounted in the shank axis direction of the shank 5, even if the base end 3a of the tool 3 is an inclined surface.

[0010]

【Example】

 The drawings illustrate one embodiment of the present invention and are described below.

A shank 5 is fitted to the spindle 2 of the cutting machine by taper fitting, and a tool 3 in this case, a drill in this case, is fitted to the tip of this shank 5 by a chuck attachment 1. A male screw body 4 is screwed into the shank 5, and a screw body 9 having a small diameter is screwed to the tip of the male screw body 4, and a tool contact portion at the tip of the screw body 9 is screwed. A spherical concave portion is formed, and a tool abutting body 6 having a spherical surface that matches the spherical concave portion and a tip end formed into a flat surface is fitted in the spherical concave portion, and the tool abutting body 6 is a screw body. It is provided so that it can be swung with respect to 9. The male screw body 4 and the screw body 9 may be integrally formed. Reference numeral 4a is a notch groove formed in a facing state for screwing the male screw body 4 into and out of the shank 5, 7 is a collet chuck, 8 is an outer cylinder, and 9a is a hexagon for screwing the screw body 9 into and out of the male screw body 4. It is a hole.

Since the present embodiment has the above-described configuration, the male screw attachment body 4 in the shank 5 is adjusted to an appropriate position in advance, and then the drill is inserted into the shank 5 to fix the base end surface 3a of the drill. The tool is brought into contact with the flat surface of the tip of the contact body 6, and the outer cylinder 8 is tightened to tighten the drill.

At this time, since the tool abutting body 6 is provided so as to be swingable, for example, even if the base end face 3a of the drill is an inclined surface due to poor accuracy, the tool abutting body 6 is tilted. Since the head follows the surface and swings appropriately, as a result, the drill is accurately inserted in the shank axis direction.

[Effect of device]

 Since the present invention is configured as described above, the tool can always be arranged in an accurate state, and thus, the tool receiver can perform the accurate work.
