[Problem that the invention attempts to solve]

Therefore, the present invention solves the above-mentioned problems, and can be used to blacken a curved workpiece while it is clamped in a vise, or when machining a curved workpiece into a wedge-shaped taper. The purpose of this is to greatly improve this type of work, which conventionally required considerable effort, by making it slanted, and to make it possible to process with high precision.

B. Structure of the invention [Means for solving the problem] In other words, the present invention has a motor and a pair of vertical saw blades and horizontal saw blades driven by the motor, which are attached to the upper and lower guiders installed upright from above the bed. In the machine, a vertical sliding part is mounted on the left and right sides so as to be vertically movable, and a reference surface perpendicular to the vertical guide bar is provided on the bed, and a vise is provided on the reference surface. One side of the mounting base is rotatably supported,
A vise inclined screw rod is pivotally attached to the other side and is screwed into the bed so that it can be screwed forward and backward in the vertical direction, and the front edge black line or side of the workpiece is brought into contact with the reference surface. Therefore, the above-mentioned problems were solved by configuring a measuring plate, such as a metal fitting, to be installed vertically so that the angle of inclination of the workpiece relative to the vertical saw blade could be measured.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. As shown in FIGS. The guide bars 2, 2 are vertically erected, and a vertical sliding portion 3 is fitted onto both the guide bars 2, 2 so as to be vertically movable.

A motor (not shown) and a pair of vertical saw blades 4 and horizontal saw blades 5 driven by the motor are pivotally supported on the left and right sides of the vertical sliding part 3, respectively, and the vertical sliding part 3 Part 3 includes upper and lower guide bars 2,
It is formed by an arm (not shown) fixed to a support member 6 that supports the upper end of 2, a push-down lever (not shown) that connects the vertical sliding part 3 with a link, and a spring (not shown) stretched between the push-down lever and the arm. It is normally held in the raised position by a balanced lever mechanism, and is lowered and raised along the upper and lower guide bars 2, 2 by pushing down or pulling up using the push-down lever.

Further, a reference plane 7 is provided at the front of the bed 1 and is perpendicular to the upper and lower guide bars 2, 2, and brackets 8 are provided at the front and rear of one side (the left side in the illustrated example) of the reference plane 7. , 8 with bolts 9, and attach the brackets 8, 8 to the front and rear of one side (the left side in the illustrated example) of the vise mounting base 10 using fulcrum bolts 11, 11 as indicated by the arrow a←→a in FIG. It is pivoted so that it can rotate in the ' direction.

As shown in FIG.
A through hole 10a is bored in parallel to the through hole 10a.
A has a through hole 13a passing through it in the vertical direction at the center, a pin 13 rotatably inserted through the through hole 13a, and opening to the outside at the up and down position corresponding to the through hole 13a, and being long in the left and right direction. Elongated holes 10b, 10b' are bored, and a vise inclined threaded rod 12 to which a rotation knob 12a is attached is rotatably but non-slidably inserted into the elongated holes 10b, 10b' and the through hole 13a. The threaded rod 12 is pivotally attached to the vise mounting base so that it can swing in the direction of arrow b←→(2)' shown in FIG. A vise mounting base 10 is supported on the bed 1 by means of a screw hole 14 opened in the reference surface 7 of the bed 1 and bored approximately vertically, and by means of an upper and lower threaded rod 12 and both of the fulcrum bolts 11, 11. Note that the mounting of the vise inclined threaded rod 12 to the vise mounting base 10 in the present invention is not limited to that by directly inserting it into the pin 13; It is also possible to provide a non-external bracket and pivot it to the vise mounting base 10 with a pin.

Two front and rear guide bars 15, 15' are installed in the vise mounting base 10 in parallel with each other at an appropriate distance in the front and rear direction and in the left and right direction. Fit and vice stand 1
6 is disposed so as to be movable in the front-back direction by a feed handle (not shown), and two left and right guide bars (not shown) are installed on the vice stand 16 in the left-right direction while maintaining an appropriate interval in the front-back direction. In addition, a feed screw shaft 17 having a reverse threaded portion in the left and right directions is installed between the left and right guide bars so as to be rotatable in the direction around the axis while preventing movement in the axial direction. 18' are screwed into the right and left reverse threaded portions of the feed screw shaft 17, respectively, and are supported by the vice stand 16 by being slidably fitted to both the left and right guide bars. 17 with the handle 19 fixed to the feed screw shaft 17.
Both vises 18 and 1 can be rotated forward or reverse.
8' move toward each other in the direction of the workpiece 2.
0, or move them away from each other to widen the distance therebetween, and unclamp the workpiece 20.

Further, in the present invention, a belt-shaped measuring plate 21 such as a bolt is attached to the front end of the reference surface 7 of the bed 1, and the measuring plate 21 is placed at the position of the ink line on the front side of the workpiece 20 clamped to the vise 18, 18', or at the position of the workpiece to be machined. The workpiece 20 is vertically fixed by bolts or the like so that the inclination of the workpiece 20 can be visually measured with respect to the vertical saw blade 4 that descends vertically in contact with the side of the workpiece 20.

Now, place the vise mounting base 10 on the reference surface 7.
When installing as described above, the reference surface 7
It goes without saying that a measuring plate mounting surface having a sufficient width to attach the measuring plate 21 must be secured in advance at the front end of the measuring plate 21 .

Further, since the vertical saw blade 4 descends in a vertical state, the measuring plate 21 is placed in the vertical position as shown in FIG. It is best to set it upright on the vertical line of the saw blade 4.

In the above configuration, when tilting the vises 18 and 18' to tilt the workpiece 20, the workpiece 20 is clamped to the vises 18 and 18', and the vice is held in such a state. Inclined screw rod 1
2 by holding its rotation knob 12a and screwing it in the direction in which the vise inclined threaded rod 12 rises,
Since the vise inclined screw rod 12 slides through the screw hole 14 of the bed 1 and rises, the vise mounting base 10, which has been in the horizontal state shown by the solid line in FIG. By being rotated in the direction of arrow a in FIG. 1, it tilts downward from the right side to the left side, and as a result, the vice stand 16 also tilts in the same way, so the vises 18 and 18' move along with the workpiece 20 as shown in FIG. It is tilted to the left as shown by the dotted line.

In addition, the vices 18, 18' and the workpiece 20
The inclination angle is determined by the helical stroke of the vise inclined screw rod 12. Furthermore, the vise inclined screw rod 12 is vertically screwed into the screw hole 14 of the bed 1, but since it is pivotally connected to the vise mount 10 by a pin 13, the inclination of the vise mount 10 cannot be changed. There is no obstruction or deformation of the threaded rod 12 itself.

Furthermore, when the vise inclined screw rod 12 is screwed in the downward direction in the state shown in FIG.
18' and workpiece 20 can be tilted in a direction opposite to the illustrated double-dashed line.

In this way, the vises 18, 18' and the workpiece 20 are tilted, and the amount of tilt (angle)
can be measured prior to actual machining using a measuring plate 21 that is set upright on the bed 1 in advance in correspondence with the vertical saw blade 4 that descends in a vertical state.

[Effect of idea]

As explained above, since the vise tilting device of the machine according to the present invention is configured, the vise is tilted on the reference surface 7 of the bed 1 provided perpendicularly to the upper and lower guide bars 2, 2 of the vertical sliding part 3. Since the mounting base 10 can be tilted and the vises 18, 18' can be tilted while the workpiece 20 is being clamped, the workpiece 20 can be tilted more easily than when the workpiece itself is tilted. Not only can the clamping of the workpiece 20 be made reliable, but also the amount of inclination can be easily and reliably determined by visual inspection using the measuring plate 21 suspended above the reference surface 7, making it easy to check the workpiece 20 and , work such as aligning the top and bottom of the curved workpiece 20 on the same surface can be done accurately and quickly, and as mentioned above, the workpiece 20 can be reliably clamped and black alignment can also be performed. By being able to do this accurately, the effects are enormous, such as being able to process wedge-shaped tapers, etc., which were previously difficult, with high precision and efficiency.
