A projection 15 is formed on the upper surface of the base 10 and the article to be machined can be held between the projection 15 and the movable body 20 and a groove 16 is formed on the upper surface of the base 10 by providing a slit 25 cut out in the Y axis direction on the upper part of the movable body 20 and also by cutting out the base 10 upper part faced to the slit 25.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise structure suitable for holding and fixing a metal rod when the metal rod is cut into a predetermined size.

[0002]

2. Description of the Related Art When a thin metal rod is cut into a predetermined size, a vise as shown in FIG. 6 is used to fix the metal rod. Reference numeral 1 is a fixed part of the vise, and 2 is a movable part. The movable part 2 is moved by turning a screw 3, and a metal rod 5 is sandwiched between the fixed part 1 and the movable part 2 to be fixed. The metal rod 5 is cut by a rotating cutter 6.

[0003]

However, with such a vise, it is difficult to fix the metal rod 5 in the correct position, and the metal rod 5 after cutting may be bent. Further, there is a drawback that when the metal rod 5 is cut, the pieces of the metal rod 5 fly and scatter.

[0004]

According to the present invention, there is provided a base having a longitudinal axis and a movable body mounted on the base so as to be movable in a direction perpendicular to the axis, and having a protrusion protruding upward. Formed on the upper surface of the base, the work piece placed on the upper surface of the base can be sandwiched between the protruding portion and the movable body, and the slit notched in the direction perpendicular to the axis is formed on the upper side of the movable body. The structure is characterized in that the upper part of the base, which is provided and is horizontally opposed to the slit, is cut out to form a groove on the upper surface of the base.

[0005]

1 to 5 show one embodiment of the vise of the present invention. As shown in the plan view of FIG. 1, the base 10, which is the fixing portion of the vise, has a longitudinal axis (referred to as the X axis). The base 10 is, as shown in the front view of FIG.
It is composed of an upper base 11 and a lower base 12 which are fixed one on top of the other. Due to the recess provided on the lower surface of the upper base 11, the base
A square hole 13 is formed on the side surface of 10 so as to penetrate in the Y-axis (FIG. 1) direction perpendicular to the X-axis. The side surface of the base 10 is also formed with a screw hole 14 penetrating in the Y-axis direction.

A movable body 20 is attached to the base 10 so as to be movable in the Y-axis direction. The movable body 20, as shown in FIG.
An upper plate portion 21 located above the upper surface 10a of the base 10,
A lower plate portion 23 located below the upper surface 10a of the base 10,
The upper plate part 21 and the lower plate part 23 are formed of a side plate part 22 in which one side ends of the upper plate part 21 and the lower plate part 23 are connected to each other. The upper plate portion 21 of the movable body 20 is divided into two by a slit 25 cut out in the Y-axis direction, and the lower plate portion 23.
One end of is inserted into the hole 13 on the side surface of the base 10.

As shown in FIG. 4, screw holes on the side surface of the base 10
The movable body 20 is connected to the base 10 by screws 30 attached to the base 14. A spring 40 inserted between the base 10 and the movable body 20 constantly urges the movable body 20 in a direction away from the base 10, and the movable body 20 is sandwiched between the knob of the screw 30 and the spring 40. Therefore, when the screw 30 is rotated, the movable body 20 moves together with the movement of the screw 30 in the Y-axis direction.

On the upper surface of the base 10, an upward protruding portion 15 extending in the X-axis direction is formed. The work piece 50 such as a metal rod is placed on the upper surface of the base 10 and the protrusion 15 and the movable body.
It is clamped between 20 and fixed. Therefore, the surfaces of the protruding portion 15 and the movable body 20 that face each other are smooth surfaces along the X-axis direction. Further, a groove 16 is formed on the upper surface of the base 10 by notching the upper portion of the base 10 that horizontally faces the slit 25. Groove 16 is protrusion 15
Across the entire width of the base 10 in the Y-axis direction.

A positioning member 60 having a smooth surface 61 formed on the side surface is attached to the end of the base 10 so as to be movable in the X-axis direction. The position of the positioning member 60 is adjusted in the X-axis direction so that the distance from the groove 16 becomes a predetermined value, and then the side surface screw 65 is tightened to be fixed to the base 10. By bringing the tip of the workpiece 50 sandwiched between the protrusion 15 and the movable body 20 into contact with the smooth surface 61 as shown in FIG. The length is determined, and the dimension after cutting or the processing position is determined. Cutting the workpiece 50
In the slit 25 of the movable body 20 and the groove 16 on the upper surface of the base 10,
It is performed by inserting the cutter 6. The workpiece 50 remains held between the movable body 20 and the protrusion 15 even after being cut into two.

[0010]

According to the present invention, even if the work piece is a thin metal rod, both sides of the portion to be cut or machined can be firmly fixed, so that the machining process can be performed accurately without bending. Further, since the cut edges do not scatter when the work piece is cut, there is an effect that productivity is improved.
