BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vice for a seal stamp material used for a cutting machine for engraving a character or the like of a seal stamp under computer control.

[0002]

2. Description of the Related Art Conventionally, there is a device as shown in FIG. 8 as a device for automatically performing cutting such as engraving under computer control. In the cutting machine 1, a rear wall 2a having built-in elevating means is erected at the rear end of the base 2, and the head 3 is provided on the rear wall 2a so as to be movable up and down. ing. A table 4 is provided on the base 2 so as to be movable left, right, front and back, and a vice 5 for fixing a material to be cut is mounted on an upper surface thereof. 6 is
Reference numeral 7 denotes a cutting tool provided on the head portion 3, and reference numeral 7 denotes a columnar seal material fixed to the vise 5.

In the case of performing cutting using the above-described cutting machine 1, first, as shown in FIG.
And the seal material 7 is fixed to the vise 5. Then, in this state, the cutting tool 6 is rotated to move the table 4 back and forth, left and right, and to move the head unit 3 up and down. Thus, the cutting tool 6 cuts the upper surface 7a of the seal material 7 and displays predetermined characters and the like.

However, in the vise 5 as described above, the holding portion 8 for holding the seal material 7.
Are constituted by a slide portion 8a which moves forward and backward by rotating the screw rod 9, and a fixing portion 8b fixed to the base portion 5a. Therefore, when the seal material 7 is attached to and detached from the vise 5, the knob 9a of the screw rod 9 is rotated to move the slide portion 8a forward and backward with respect to the fixing portion 8b, and the fixing portion 8b stops. Has been left.
For this reason, the number of rotations of the knob 9a at the time of attaching and detaching the seal material 7 increases, and there is a problem that it takes a long time to attach and remove the seal material 7 and the operation is troublesome.

When a seal material 7 having a different diameter is attached to the vise 5, the position of the center point of the seal material 7 with respect to the vise 5 changes according to the diameter. For this reason, every time the seal material 7 is replaced, the center point must be set again, which has a problem that the operation is complicated. Furthermore, since the vise 5 has only one screw rod 9, when the slide portion 8a is moved forward and backward, the slide portion 8a is easily distorted with respect to the fixing portion 8b, and the fixed seal material 7 is displaced in the left-right direction. , May float upward. As a result, there also arises a problem that the cutting accuracy is deteriorated due to an increase in the cutting depth.

The present invention has been made in view of such circumstances, and simplifies the work of attaching a seal material, and eliminates the need to reset the center point even when attaching a seal material having a different diameter. Further, an object of the present invention is to provide a vise for a seal material, which can fix a seal material at an appropriate position in an appropriate state, thereby enabling accurate cutting.

By rotating the knob 19, both slide portions 2
1 and 22 can be moved closer and further away from each other. Therefore, the operation time is greatly reduced as compared with the conventional vise 5 in which only one slide portion 8a is moved, and the operation is simplified. In addition, since the center point when the seal material 30 is fixed to the vise 10 is always constant, it is not necessary to set the center point again and the operation becomes easy.

Further, since the two screw rods 12 and 13 are used, the positional relationship between the two slide portions 21 and 22 can always be maintained in a parallel proper state, and the two slide portions are fixed. There is no lateral displacement or upward lifting of the seal material 30. As a result, the seal material 30 can be fixed in an appropriate state, and accurate cutting can be performed. Further, since the vise 10 can cut various seal materials 30 having different sizes, it is not necessary to replace the holding portion 8 which is conventionally required, and the usability is extremely improved. 8 can be prevented from occurring.

Further, in the vise 10, the peripheral surfaces of the holes 23 and 24 of the slide portions 21 and 22 are smooth sliding surfaces, and the center portions of the threaded rods 12 and 13 are formed on the sliding surface portions 12c and 13c. Because it is formed, the slide part 2
1 and 22 move smoothly without rattling. Also, the screw rods 12 and 13 and the slide part 21,
Since the number of threaded portions 22 is small, the thread cutting process is simplified, and the number of screwed portions of the threaded portions is small, so that the sliding portions 21 and 22 can move smoothly even if the dimensional accuracy of the threaded portions is somewhat poor. .

In the vise 10, the notch 27
Since the small notches 27c and 29c are provided at the corners of the seal stamps b and 29b, the corners of the seal stamp material 30 contact the corners of the cutouts 27b and 29b when the seal stamp material 30 having a square cross section is attached. Instead, the notch 27b, 29b or the seal material 3 is inserted deeply into the notch 27b, 29b.
Even if the 0 corners are not right-angled with high precision, it is possible to perform reliable holding. Further, in the vise 10, the distal end portion 29a of the insertion portion 29 is
Can be inserted into the insertion hole 27a. Therefore,
The flat cylindrical portion 27 and the insertion portion 29 are
