[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vice device for a machine tool, and more particularly to a moving mechanism for a moving vise.

[0002]

2. Description of the Related Art In general, a vise device is widely known as a device for holding and holding a workpiece to a machine tool.

[0003] This vice device is usually composed of a fixed vise and a movable vise, and the moving mechanism of the movable vise is as follows.
A moving vise is attached to one end of a screw shaft, and the position of the moving vise with respect to the vise bracket is changed by rotating the screw shaft.

[0004]

However, in the above-described structure, for example, after a work piece of one length (300 mm) is sandwiched, when the work material of four dimensions (120 mm) is sandwiched, the moving vise is set to ( (300-120 = 180 mm). If the normal screw pitch is 2 mm, the handle must be turned 180 times / 2 mm = 90 times, which is troublesome.

The present invention has been made in view of the above-mentioned problems, and has as its object to provide a vise device for a machine tool that can quickly move a moving vise according to the size of wood. .

[0006]

The present invention provides a fixed vise,
Vise bra spaced from the fixed vise
And a moving vial at one end facing the fixed vise.
Screw shaft with clamp handle at the other end
And attaching the screw shaft to the vice bracket so that the movable vise can be moved far and near with respect to the fixed vise.
And a moving vise mechanism for mounting the machine, the moving vise mechanism being mounted on an inner peripheral surface of the machine tool .
The screw shaft is screwed, and the outer peripheral surface
Holder having screw cylinder portion screwed to vise bracket
And a female screw portion engageable with a screw thread of the screw shaft,
Engagement of the female screw portion with the thread of the screw shaft and its disengagement
The holder is provided rotatably so as to enable removal.
And the female screw of the lever with the screw shaft.
Between the lever and the holder so as to engage
And an elastic member provided therebetween .

[0007]

When the moving vise is moved, the lever is rotated against the urging force of the elastic member to release the screwing between the screw portion and the screw shaft. In this state, the screw shaft is moved, and the workpiece is temporarily fixed with the fixed vice and the moving vise. And
The lever is rotated again, and the screw portion and the screw shaft are screwed together. By rotating the screw shaft, the moving vise is moved to the fixed vise side, and the workpiece is fixed. Further, when the holder is rotated, the holder integrated with the screw shaft moves by screwing the screw cylinder and the screw hole, and the workpiece can be firmly fixed.

0. That is, reference numeral 1 in the figure denotes a fixed vise, and one end of a front and rear guide shaft 2 is attached to the fixed vise 1. A moving vice mechanism 3 is attached to the other end of the front and rear guide shaft 2. A base 4 is provided on the front-rear guide shaft 2 so as to be movable in the axial direction of the front-rear guide shaft 2, and a column 5 is provided upright on the base 4. A holder 6 is attached to an upper portion of the support 5, and a drive motor 7 is housed in the holder 6.

FIG. 2 is an enlarged view of the moving vice mechanism 3. In the figure, reference numeral 11 denotes a vise bracket together with the screw cylinder 12.
The vise bracket member is a part of the vise bracket member, and is fixed to the end of the front and rear guide shaft 2. The vice bracket member 11 has a cylindrical portion 11a, and a hole 11b is formed in the bottom of the cylindrical portion 11a. In addition, this cylindrical portion 11
A screw cylinder 12 is inserted into a, and its rotation is regulated by a pin 13. Further, the screw cylinder 12 and the cylinder 11
a spring 23 is interposed between the screw cylinder 1 and the cover 14 of FIG.
2 is constantly urged to the left in the figure to restrict axial movement. Further, a female screw portion 12 a is formed on the inner peripheral portion of the screw cylinder 12. Further, the holder 1 is provided in the screw cylinder 12.
The fifth threaded tube portion 15a is inserted and screwed. A screw shaft 16 is inserted into the holder 15 so as to be movable in the axial direction. A moving vise 17 is fixed to one end of the screw shaft 16, and a clamp handle 18 is fixed to the other end. As shown in FIG. 3, the hollow portion 15 of the holder 15 is
b and a lever insertion portion 15c that communicates with the outside is formed,
The lever 19 is inserted into the lever insertion portion 15c. In FIG. 2, the lever 19 has a projection 19 a formed on the side thereof and a recess 15 formed on the holder 15.
By being engaged with d, it is held rotatably. The lever 19 has a female thread 19b. The holder 15 is provided with a leaf spring 20 as an elastic member, and constantly biases the lever 19 counterclockwise around the projection 19a in FIG. Thus, the female screw portion 19b is always screwed to the screw shaft 16. In FIG. 3, the handle 15 for retightening is attached to the holder 15. The screw pitch of the screw cylinder 15a is set to be much larger than the screw pitch of the screw shaft 16.

The moving vice mechanism 3 constructed as described above
The operation of fixing and holding the work material using will be described below. In FIG. 1, a workpiece 22 is positioned between a fixed vice 1 and a movable vise 17. At this time,
As shown in FIG. 1, when the clamping width of the workpiece 22 is extremely smaller than the distance between the fixed vice 1 and the moving vise 17 at the current position, the lever 19 is moved to the leaf spring 20 in FIG.
2 is rotated clockwise about the protrusion 19a in FIG. 2 to release the screwing between the female screw 19b and the screw shaft 16. In this state, the screw shaft 16 is moved in the axial direction, and the moving vise 17 is brought into contact with the workpiece 22 (FIG. 1). In this state, the lever 19 is rotated by the urging force of the leaf spring 20, and the female screw portion 19b and the screw shaft 16 are screwed. Then, the clamp handle 18 is rotated. Accordingly, the screw shaft 16 moves forward and backward with respect to the holder 15 by screwing with the female screw portion 19b. Thereby, the workpiece 22 (FIG. 1) can be fixedly held. Further, by rotating the additional tightening handle 21 (FIG. 3), the holder 15 is rotated. Thereby, the screw cylinder 1
5a is also rotated, but since the screw tube portion 15a is screwed to the screw tube 12 provided with the rotation and axial movement thereof being regulated by the vice bracket member 11, the holder 15 is attached to the vice bracket member 11 To the left in the figure. At this time, since the screw pitch of the screw cylinder portion 15a is set to be larger than the screw pitch of the screw shaft 16, the moving vise 17 moves greatly by slightly turning the re-tightening handle 21. Thereby, the moving vise 17 also moves in the direction to clamp the workpiece 22 (FIG. 1), and the holding and fixing becomes stronger.

In this state, in FIG. 1, the drilling operation is performed by operating the drive motor 7 of the chain-only machine and pushing down the holder 6. In the case of drilling a plurality of holes in the same workpiece, by rotating the retightening handle 21 in a loosening direction, a gap is generated which can shift the position of the workpiece. Only the fastening handle 21 needs to be used, and the workability is improved.

In the above-mentioned embodiment, the case of using only a chain machine has been described. However, the use of the vice device in the present invention is not limited to the machine using only chains, and other machine tools may be used. good. In this specification, the vice bracket includes a vise bracket member 11 and a screw tube 12, but the screw tube 1
2 is not necessarily required. For example, even if a screw hole is formed in the vise bracket member 11, it is possible to expect substantially the same operation and effect as the above-described embodiment.

[0013]

[Effect of the Invention] The present invention is constructed as described above. By rotating the lever and releasing the screw engagement with the screw shaft,
Since the screw shaft can be quickly moved in the axial direction,
The moving operation of the moving vise can be performed efficiently.
Further, when performing a plurality of operations on the same workpiece, by rotating the holder, it is possible to easily generate a gap that allows the workpiece to be moved. Thus, there is an effect that the workability can be improved.
