Description

[Detailed explanation of the idea] [Field of application of invention] The present invention relates to a cutting machine.

[Background of the idea]

The prior art will be explained using FIGS. 5 and 6.

1 is the base. 2 is a turntable rotatably supported on the upper part of the base 1; 3 is a fixed vice fixed to the upper surface of the base 1 and disposed above the turntable 2; 4 is a turntable 2.
It is a cutting blade that is vertically swingable with respect to the upper surface, rotates integrally with the turntable 2, and is disposed above the base 1. Reference numeral 5 denotes a moving vise supported on the front upper surface of the base 1, and is adjusted to move back and forth in a direction perpendicular to a material support surface 6 formed on the front surface of the fixed vise 3.

In the cutting machine having the above configuration, when providing inclined surfaces at both ends of the cylindrical cutting material 19 as shown in FIG. 6, conventionally the cutting material 19 is supported between the fixed vice 3 and the moving vice 5 When trying to cut the cutting material 19 into the shape shown by the solid line in FIG. 6, the cutting material 19 is rotated as shown by the broken line in FIG. 6 as the cutting blade 4 rotates, and the other end There was a drawback when the sides were cut off.
For this reason, the cutting directions of the sloped surfaces at both ends do not match,
When the inclined surfaces of a plurality of cylindrical members are used in conjunction with each other, the result is a twisted combination. Therefore, there are inconveniences such as having to recut the cut each time or discarding the cut material.
It has been considered extremely difficult to provide accurate slopes at predetermined positions.

[Purpose of invention]

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to enable angle cutting of the ends of cut materials in this type of cutting machine to be performed efficiently and accurately.

[Summary of the idea]

In addition to the movable vise provided on the front upper surface of the base, this invention also provides a stopper that can be slid and rotated from the side, thereby reducing the amount of material cut in shapes that are insufficiently held down. The structure of the stopper has been devised by focusing on the points that can be made.

[Example of idea]

An embodiment of the present invention will be described with reference to FIGS. 1 to 4. Note that parts that are the same as those in the prior art are designated by the same reference numerals and their explanations will be omitted.

7 is Natsuto. A shaft 8 parallel to the material support surface 6 is attached to the side surface of the base 1 via a nut 7.
to be fixed. One end of a holder 9 is fitted onto the shaft 8, and the holder 9 is supported via a fixing member 10 so as to be slidable and positionable on the shaft 8. On the other hand, a shaft 11 parallel to the shaft 8 is supported at the other end of the holder 9 so as to be slidable and positionable via a fixing member 12 provided on the holder 9. Further, a stopper 14 rotatably supported by a pin 13 is provided at the tip of the shaft 11, and a plurality of recesses 15 are provided on the inner surface of the stopper 14 on an arc line around the pin 13. Furthermore, by forming a vertical hole 16 in the shaft 11 corresponding to the position of the recess 15, and equipping the vertical hole 16 with a ball 18 via a compression spring 17,
The fitting of the recess 15 and the ball 18 constitutes a stopper positioning means.

In the above structure, when providing bilaterally symmetrical inclined surfaces at both ends of a cylindrical material to be cut as described in the conventional example, as shown in FIG. By tilting the cutting blade 4 and lowering the cutting blade 4, an inclined surface is provided on one end side of the cutting material 19.

Next, if an inclined surface is provided on the other end side of the material to be cut 19, the previously provided inclined surface is brought into contact with the stopper 14 and brought into alignment. Adjustments at this time can be made by adjusting the fixing members 10 and 12 according to the shape of the material to be cut 19 and by adjusting the rotation of the stopper 14 to set it at the optimum position.

In this way, the stopper 14 and the cutting material 1
9, the moving vice 5 is tightened, the material to be cut 19 is supported on the base 1, the cutting blade 4 is used to obtain an inclined surface, and both ends are symmetrically inclined. A workpiece with surfaces is completed.

[Effect of idea]

According to the present invention, a shaft is provided on the side surface of the base parallel to the material support surface of the fixed vise provided on the upper surface of the base, a holder that is slidable and positionable is provided on the shaft, and the holder has a tip end portion. The shaft is equipped with a stopper that can be rotated and positioned so that it can be slid and positioned, so it can reliably cut materials that have shapes that could not be adequately held down by the movable vise installed on the front upper surface of the base. It can provide much more efficient cutting work than conventional methods.
