Abstract

(57) [Summary] [Purpose] To obtain a stable positioning mechanism for the presser foot 6 in the clamp holder. [Structure] A cutting edge tip 3 arranged in a tip seat 2 of a holder body 1 is attached by a presser foot 6 having a tightening screw 4. This presser foot 6 has a pressing portion 6 against the cutting edge tip 3 at one end, and a positioning mechanism including first fitting unevennesses 8 and 10 and second fitting unevennesses 9 and 11 at the other end. Is configured. The presence of this positioning mechanism restricts the movement of the presser foot 6 in the X direction and the Z direction with respect to the cutting blade tip 3, so that the stability of the clamp is obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clamp holder for parting, grooving, etc., and more particularly, to a cutting edge tip that can be reliably fixed by a presser foot having a tightening screw.

[0002]

[Prior art]

 Conventionally, as this type of clamp holder, for example, one disclosed in Japanese Patent Laid-Open No. 3-149105 has been disclosed. In the clamp holder disclosed in this publication, the cutting edge tip in the tip seat is fixed by a presser foot having a tightening screw, and the rear lower surface of the presser foot is tapered by an inclination angle β. The pressing protrusion surface is formed.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned clamp holder has a problem that it is insufficient as a clamping mechanism for the cutting edge tip because it is only laterally displaced by the pressing projection surface as a positioning mechanism for the presser foot.

In view of the above, the present invention has been improved so that the presser foot can be accurately positioned with respect to the holder body.

[0005]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and a presser foot for fixing a cutting blade tip has a pressing portion for the cutting blade tip formed at one end and a holder main body at the other end lower surface. The positioning mechanism including the first and second fitting irregularities is configured between the two. The movement of the positioning mechanism including the first and second fitting irregularities is restricted in both the X direction in the length direction of the cutting blade tip and the Z direction in the width direction of the cutting blade tip. It was done so.

[0006]

[Action]

 Since the clamp holder of the present invention is provided with the presser foot having the positioning mechanism whose movement is restricted in the X direction and the Z direction, the clamp for the cutting edge tip is reliably performed. Therefore, it is effective in cutting operations such as parting and grooving.

【Example】

 An embodiment of the clamp holder of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment, in which 1 is a holder main body having a tip seat 2 formed at one end, and a cutting blade tip 3 is arranged in the tip seat 2. There are The cutting edge tip 3 is attached by a presser foot 6 in which a tightening screw 4 is fitted in a mounting hole 5.

The presser foot 6 is formed with a pressing portion 7 against the cutting edge tip 3 at one end, and from the first and second fitting irregularities 8 and 9 at the other end with the holder body 1. The positioning mechanism is constructed.

That is, the first fitting unevenness 8 regulates the movement of the cutting edge tip 3 in the X direction, which is the length direction, and the V groove 8 a and the presser foot formed on the holder body 1 side. It is composed of a rounded protruding portion 8b formed on the 6 side. The second fitting irregularities 9 restrict the movement of the cutting edge tip 3 in the Z direction in the width direction, and on the holder body 1 side, the key portion 9a and the key portion 9a formed in the intermediate portion of the V groove are formed. It is composed of a groove portion 9b formed on the presser foot 6 side. The relationship between the first and second fitting irregularities 8 and 9 is illustrated in FIGS. 2 and 3. In this case, as for the second fitting unevenness 9, the key portion 9a may be formed of a pin as seen in FIG. Further, the tip seat 2 with respect to the cutting edge tip 3 is preferably a V-shaped projection or a V-shaped recess for clamping.

Further, the clamp holder of the second embodiment shown in FIG. 5 exemplifies a positioning mechanism composed of first and second fitting concaves and convexes 10, 11.

That is, the first fitting unevenness 10 is formed by the first V-shaped groove 10 a formed on the holder body 1 side and the V-shaped first protruding portion 10 b formed on the presser foot 6 side. It is composed of Further, the second fitting irregularities 11 are constituted by the second V groove 11a on the holder body 1 side and the V-shaped second protruding portion 11b formed on the presser foot 6 side. In this case, the fitting irregularities 10 and 11 have a fitting state as shown in FIG. 6, but the movement thereof is restricted in the X direction and the Z direction as described above.

The first V-shaped groove 10a and the second V-shaped groove 11a are configured to intersect each other in a T-shape with a V-shaped angle θ as shown in FIGS. 7 (a) to 7 (c). It However, with respect to the presser foot 6, the cases of intersecting in a T-shape and the case of dividing as shown in FIGS. 8A to 8C and FIGS. 9A to 9C are applied.

[0014]

[Effect of device]

 As described above, the clamp holder of the present invention employs the presser foot 6 whose movement is restricted in the X direction and the Z direction, so that the clamp of the presser foot 6 is stable and cuts off. It is effective in cutting such as grooving.
