DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

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

[0003]

However, in such a vise, it is difficult to fix the metal bar 5 at a correct position, and the metal bar 5 after cutting may be bent. Further, there is a disadvantage in that the cut ends of the metal bar 5 fly and scatter when cut.

SUMMARY OF THE INVENTION The present invention provides a base having a protruding portion extending in the X-axis direction formed on an upper surface thereof, and a movable body mounted on the base so as to be movable in a Y-axis direction perpendicular to the X-axis. And a positioning member having a smooth surface on the side surface and movably mounted in the X-axis direction and attached to an end of the base, wherein the workpiece placed on the upper surface of the base is moved between the protrusion and the movable body. A slit that can be clamped and one end of the workpiece can be brought into contact with a smooth surface, a slit cut out in the Y-axis direction is provided at the upper part of the movable body, and a groove that is horizontally opposed to the slit and crosses the protruding portion is provided. Is characterized in that it is formed on the upper surface of the.

1 to 5 show an embodiment of a vice according to the present invention. As shown in the plan view of FIG. 1, the base 10, which is a vice fixing portion, has a longitudinal axis (referred to as an X axis). As shown in the front view of FIG.
It is composed of an upper base 11 and a lower base 12 which are vertically fixed and fixed. The recess provided on the lower surface of the upper base 11 allows the base
A rectangular hole 13 penetrating in the Y-axis (FIG. 1) direction perpendicular to the X-axis is formed on the side surface of the 10. On the side surface of the base 10, a screw hole 14 penetrating in the Y-axis direction is formed.

A movable body 20 is mounted on 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 21 and the lower plate 23 are formed of a side plate 22 that connects one end of the lower plate 23 to each other, and the whole is integrally formed in a substantially U-shape with metal. 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.
Is inserted into a hole 13 on the side surface of the base 10.

[0007] As shown in FIG.
The movable body 20 is connected to the base 10 by a screw 30 attached to 14. The movable body 20 is always urged in a direction away from the base 10 by a spring 40 inserted between the base 10 and the movable body 20, and the movable body 20 is sandwiched between the knob 30 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.

[0008] On the upper surface of the base 10, an upward protruding portion 15 extending long in the X-axis direction is formed. The workpiece 50 such as a metal bar 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. For this reason, the mutually opposing surfaces of the protruding portion 15 and the movable body 20 are formed as smooth surfaces along the X-axis direction. In addition, a groove 16 is formed on the upper surface of the base 10 by cutting out the upper part of the base 10 that is opposed to the slit 25 in the horizontal direction. Groove 16 is protrusion 15
And extends over the entire width of the base 10 in the Y-axis direction.

A positioning member 60 having a smooth surface 61 formed on a side surface is attached to an end of the base 10 so as to be movable in the X-axis direction. After the position of the positioning member 60 in the X-axis direction is adjusted so that the distance from the groove 16 becomes a predetermined value, the positioning member 60 is fixed to the base 10 by tightening the screw 65 on the side surface. The tip of the workpiece 50 sandwiched between the protrusion 15 and the movable body 20 is brought into contact with the smooth surface 61 as shown in FIG. The length is determined, and the size or processing position after cutting is determined. The cutting of the workpiece 50 is
In the slit 25 of the movable body 20 and the groove 16 on the upper surface of the base 10,
This is performed with the cutter 6 advanced. The workpiece 50 is retained between the movable body 20 and the protruding portion 15 even after being cut into two pieces.

[0010]

According to the present invention, even when the workpiece is a thin metal rod, both sides of the portion to be cut or machined can be firmly fixed, so that the machining can be performed accurately without bending. In addition, there is an effect that productivity is improved because the cut ends do not scatter when cutting the workpiece.
