Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise apparatus for a horizontal band saw having a fixed vice for fixing a material and a moving vise.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional vise device includes a fixed vise 7 fixed to the upper surface of a base 2 and a base 2.
The structure is such that the material 11 is fixed by the moving vise 8 sliding in the groove.

[0003]

[Problem to be solved by the invention]
When tightening the material 11, the play of the sliding part of the moving vise 8 and the deformation of the moving vise 8 cause the material 1 to float and to be surely lifted.
1 could not be fixed. For this reason, there has been a problem that the cutting accuracy is deteriorated, the band saw blade is chipped, and the life is shortened. SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned disadvantages of the prior art, and to provide a vise device for securely fixing a material even when a moving vise rises during material tightening.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to move a vice plate having a grooved inclined surface in the vertical direction of a vise surface of a moving vise and having a grooved inclined surface corresponding to the groove. The vice plate is fitted to the vise surface of the vise, and the vice plate is slidably mounted in a vertical direction, and the vice plate is held by a leaf spring fixed to the bottom surface of the moving vise.

[0005]

In the vice device configured as described above, the moving vise floats due to the play of the moving vise sliding portion and the deformation of the moving vise due to the tightening force at the time of material tightening. The vice plate has a downward force acting on the vice plate, and at the same time the force pressing the material against the upper surface of the base due to the frictional force between the vice plate and the material. work. Further, the leaf spring fixed to the bottom surface of the moving vise urges the lower surface of the vise plate to be in a position substantially coincident with the upper surface of the base when the material is not tightened. At the time of material tightening, the leaf spring is elastically deformed by a downward component force acting on the vise plate, and lowers the vise plate within a certain range.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a detailed view of a moving vise portion of the present invention, FIG. 3 is a detailed view of a moving vise portion when material is tightened, and FIG. FIG. In the drawing, a base 2 is provided on a pedestal 1, and a frame 3 is pivotally supported at the rear end of the base 2 so as to be vertically swingable. In the frame 3, a driving side saw wheel 4, a driven side saw wheel 5 interlocked with the driving side saw wheel 4, and a band saw blade 6 stretched between the saw wheels 4, 5 are provided. I have. Base 2
A fixed vise 7 and a movable vise 8 are mounted on the upper side. The moving vise 8 is movably mounted on the upper surface of the base 2 so as to be guided by a groove formed in the longitudinal direction of the base 2. The material 11 is held and fixed by a vice device including a fixed vice 7 and a moving vise 8. A groove 8a is formed in the vertical direction of the obtuse inclined surface 8b of the moving vise 8, and a dovetail 9a corresponding to the dovetail groove 8a is formed into an acute inclined surface 9b of the vice plate 9.
Is formed. The inclined surface 9b of the vise plate 9 and the inclined surface 8b of the moving vise 8 are fitted, and the vise plate 9 is slidable in the vertical direction with the movable vise 8 guided by the dovetail groove 8a. The opposite surface of the inclined surface 8b is a surface which comes into contact with the material 11 and is formed perpendicular to the upper surface of the base 2. One end of a leaf spring 10 is fixed to the lower surface of the moving vise 8 with a screw, and the other end of the leaf spring 10 is located on the lower surface of the vise plate 9. When the material 11 is not tightened, the lower surface of the vise plate 9 and the base 2 are fixed. It is urged so that the upper surfaces are maintained in substantially the same state. In the above-described configuration, as shown in FIG. 2, the mounting surface of the moving vise 8 and the vice plate 9 has a structure in which the inclination angle is θ degrees. As shown in FIG. 3, when the material 11 is tightened with the tightening force Fv. , Moving vise 8
, A downward component force Ft = Fvtanθ acts on the vise plate 9 and the vise plate 9 slides downward. At this time,
Due to the frictional force between the vice plate 9 and the material 11, the material 11
A downward force acts on the base 2 and is pressed against the upper surface of the base 2. When the material 11 is tightened, the leaf spring 10 is elastically deformed by a downward component force acting on the vise plate 9 to lower the vise plate 9 within an arbitrary range. As shown in FIG. 2, when the tightening of the material 11 is loosened, the vise plate 9 is lifted to a normal position and held by the restoring force of the leaf spring 10.

[0007]

According to the present invention, the sliding surface between the moving vice and the vise plate is inclined, and a downward component force acts on the material when tightening the material, so that the material does not float from the upper surface of the base. Can be fixed securely. For this reason, the cutting accuracy can be improved, and the life of the band can be improved by preventing the chipping of the band.
