Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vise device for a cutting machine that holds and fixes a member to be cut.

[Conventional technology]

FIG. 8 is a side view of a vise device of a conventional cutting machine. The vise device for holding a member to be cut 4 placed on the base 1 at the time of cutting is composed of a fixing portion 2 mounted on the base 1 and a screw. The movable portion 3 is slidable on the base 1 by the tightening mechanism, and the wall surface of the fixed portion 2 and the movable member 3 which holds the member to be cut 4 is perpendicular to the surface of the base 1.

FIG. 9 is a side view of a vise device for a cutting machine showing another conventional example. In this example, when holding a cylindrical member such as a round pipe or a round bar, a force in the direction perpendicular to the base 1 surface is applied. In order to suppress it, the wall surface of the fixed portion 2 is inclined toward the movable portion 3 side.

[Problems to be solved by the device]

In the conventional example as shown in FIG. 8, when the member to be cut is a cylindrical member such as a round pipe or a rod, the member to be cut is in line contact with the fixed part and the movable part and is fixed only by a horizontal force, so that cutting is performed. The vertical force generated from the reaction force of the blade and the rotational force of the saw blade lifts the member to be cut, which causes the cutting accuracy to deteriorate.

If the wall surface of the fixing portion is inclined as shown in FIG. 9 in order to prevent such lifting, a problem may occur when fixing a member to be cut other than the cylindrical member shown by the chain double-dashed line. There was a flaw.

The present invention solves the drawbacks of the prior art, prevents the cylindrical member from rising, and can hold not only the cylindrical member but also members to be cut of various shapes to improve the accuracy of cutting. The purpose is to provide.

[Means for Solving the Problems]

In the present invention, a support member fixed to the base on the fixed portion,
A plate that has a wall surface that abuts against the member to be cut and that is rotatably supported by a pin that is attached to the lower portion of the support member, and a plurality of holes that are attached to the upper and both ends of the plate and that have a plurality of long grooves. An arm having an engaging portion that communicates with each other, and a shaft having an engaging hole switching lever that engages with the hole of the engaging portion at both ends and is rotatable in a direction perpendicular to the longitudinal direction of the plate. The hole of the engaging portion with which the shaft is engaged is switched by operating the engaging hole switching lever so that the plate wall surface becomes vertical to the base surface or tilts toward the movable portion. It is characterized by

[Action]

In the present invention, an arm is attached to the upper part and both ends of the plate, and a plurality of holes are engaged with both ends of the shaft,
An engaging portion having a long groove that allows the holes to communicate with each other is provided, and the engaging portion switching lever provided near the central portion in the longitudinal direction of the shaft is operated to switch the engaging hole with which the shaft engages and the plate wall surface is used as a base. It is designed to be inclined to the movable portion side which is perpendicular to the surface or is opposed to the surface.

Therefore, when holding the cylindrical member, it is possible to prevent the member from rising by inclining the plate wall surface, and in the case of other members, the plate is perpendicular to the base surface and the member to be cut can be cut without causing a problem. The accuracy of gripping and cutting can be improved.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a cutting machine according to this embodiment. In the figure, 1 is a base, 2 is a fixed part of a vise device disposed on the base 1, 3 is a movable part thereof, and 3 is a movable part. The tightening mechanism 5 using a screw slides on the base 1, and the member to be cut 4 is held and fixed by the movable portion 3 and the fixed portion 2. 6 is a saw blade, 7 is a cover for covering the saw blade 6, 8 is an arm, 9 is a hinge, and the arm 8 is rotatably supported by the hinge 9 by the hinge shaft 10 and is rotatably attached to the arm 8. The saw blade 6 cuts the member 4 to be cut.

2 and 3 are side views of the fixing portion 2 of the vise apparatus according to the present embodiment, and FIG. 4 is a sectional view taken along the line AA of FIG. 2. In FIGS. 2 to 4, 10 is a base. 1, an L-shaped support member fixed to 1, a plate having a wall surface 11a that abuts against the member to be cut 4, 12 is a lower portion of the plate 11, lower arms provided at both ends, and 13 is a lower portion of the support member 10. With the attached pins, the plate 11 is rotatably supported by the support member 10 by the pins 13 via the lower arm 12. Reference numeral 14 denotes an upper arm provided at the upper end and both ends of the plate 11 and provided with a plurality of holes 14a, 14b and an engaging portion 14d made of a long groove 14c for communicating these holes with each other. 15 is an engaging portion 14d at both ends
The shafts that engage with the holes 14a and 14b are provided with an engagement hole switching lever 16 in the longitudinal direction and in the vicinity of the center.

FIG. 5 is a top view of an essential part of FIG. 2, in which the cutout groove 10 is provided in the upper portion of the support member 10 where the engagement hole switching lever 16 is attached.
a is provided, and the engagement hole switching lever 16 is rotatable rightward from the upright state.

In the above structure, when the engaging hole switching lever 16 is now operated to engage the shaft 15 with the hole 14a of the engaging portion 14d, the plate wall surface 11a becomes vertical to the surface of the base 1 as shown in FIG. Become.

Further, when the shaft 15 is engaged with the hole 14b of the engaging portion 14d,
The plate wall surface 11a is a movable part 3 facing each other as shown in FIG.
Tilt to the side.

Next, the engaging hole switching mechanism and its operation will be described with reference to FIGS. 6 and 7 (a) to (e).

FIG. 6 is a sectional view taken along line BB of FIG. 5, FIG.
(E) is an explanatory view showing a state where the engagement hole of the shaft 15 is switched.

In FIG. 7 (a), the end portion 15a of the shaft 15 is engaged with the hole 14a and the plate wall surface 11a is perpendicular to the surface of the base 1. However, the shaft engaged with the holes 14a, 14b is shown. Since the end portion 15a of 15 is a strip-shaped projection with both sides cut out so that it can pass through in the long groove 14c, when the engagement hole switching lever 16 is now rotated from the upright state to the right, the strip-shaped projection is also formed. After turning, the state shown in FIGS.
The state shown in FIG. 3D is obtained and the engagement holes are switched. Therefore, the switching is completed by returning the engagement hole switching lever 16 to the original upright state as shown in FIG. 7 (e).
