Abstract

PURPOSE:To set an adequate opening amount between bases in a vise simply. CONSTITUTION:A pointer scale 7 is provided at the side surface of a vise frame 1, and the pointer scale 7 is set to make the origin position of the pointer scale 7 coincide with the standard position of a base 3. After the standard position of a base 5 at a movable latch side is made to coincide with a scale position a little larger than a work on the pointer scale 7, the work is fastened between both bases 3 and 5, and fixed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise, and more particularly to an improvement in a technique for setting the opening amount of a mouthpiece when a work is first attached to the vise.

[0002]

2. Description of the Related Art Generally, when mounting a work on a vise, the opening amount between the fixed and movable jaw caps is set according to the size of the work, and then the work is placed between the caps and the movable jaw is fixed to the fixed jaw. The work is clamped and fixed between the mouthpieces by moving it toward. If the opening amount between the bases is too large in this work, the moving distance of the movable jaw after the work becomes large, and the work and time loss increases and the work efficiency decreases.

[0003]

Conventionally, the setting of the opening amount between the caps has been performed by the operator's visual confirmation or the confirmation using a scale. However, such a setting method is inefficient because it depends on the intuition or skill of the operator. Especially in the case of a stepped mouthpiece, if the opening amount is too large, the work cannot be placed on the stepped portion of the mouthpiece, so that the opening amount must be set accurately. In other words, this is the reason why a technique for easily setting an appropriate opening amount between the caps is required.

The present invention intends to meet such a demand, and an object thereof is to easily set an appropriate opening amount between the caps.

[0005]

Therefore, in the present invention, a scale plate is provided on the side surface of the vise frame, and the origin position of the scale plate is arranged so as to match the reference position of the mouthpiece on the fixed jaw side. And

[0006]

Operation: With the origin position of the scale plate aligned with the reference position of the die on the fixed jaw side, the reference position of the die on the movable jaw side is adjusted to a scale position slightly larger than the size of the workpiece on the scale plate. In this state, the work is arranged between the two caps and the movable jaw is moved to clamp and fix the work between the two caps.

[0007]

1 and 2 show an example of a vise according to the present invention, in which a work is clamped between the jaws of both jaws.
It is a normal type of vise that is fixed. A fixed jaw having a mouthpiece 3 is fixed to one end of the upper surface of the vise frame 1, and a movable jaw having a mouthpiece 5 is movably provided facing the fixed jaw. A scale plate 7 is housed in the horizontal groove 1a formed on the side surface of the frame 1, and its position can be fixed by a fastening screw 9 and a holding plate 11. Normally, the origin position of the scale plate 7 (that is, the position where the scale is zero) is aligned with the reference position of the fixed jaw side die 3 (that is, the surface that comes into contact with the work). This state is called the initial state.

When mounting the work on the vise, the reference position of the movable jaw side cap 5 is set to the scale plate 9 in the above-mentioned initial state.
Adjust the scale position to a value slightly larger than the outer dimension of the work above. In this state, place the work between the mouthpieces 3 and 5,
The movable jaw is moved to tighten and fix the work between the mouthpieces 3 and 5.

By the way, it is necessary to change the fastening force applied to the work according to the processing applied to the work, and accordingly, it is necessary to use a die having a thickness (dimension in the fastening direction) that can sufficiently withstand the fastening force. . That is, when the specification of the mouthpiece is changed, the reference position of the fixed jaw side mouthpiece 3 is changed from that before the specification change (even if the position of the fixed jaw itself is not changed). In order to cope with such a situation, it is desirable that the scale plate 7 be configured to be movable in the horizontal direction (the direction in which the scale is graduated). In this embodiment, if the fastening screw 9 is loosened, the scale plate 7 can be moved. It can be moved left and right by the desired amount.

FIG. 3 shows an example in which a mouthpiece on the fixed jaw side is applied to a vise attached to the rear of the fixed jaw, and a scale plate 7 is provided so that the reference position of the mouthpiece 5 on the movable jaw side can be seen more easily. An auxiliary pointer 13 that indicates the reference position of the portion that is close to is attached to the movable jaw.

FIG. 4 shows the present invention applied to a vise having a stepped die. In this case, since the reference positions of both caps 3 and 5 are apart from the scale plate 7, it is difficult to match the origin position of the scale plate with the reference position of the cap. Therefore, in this example, arrows 15 and 17 are provided at positions corresponding to the reference positions of the mouthpiece 3 on the fixed jaw side and the mouthpiece 5 on the movable jaw side in the portions of both jaws approaching the scale plate 7.

Although the scale plate 7 which is separate from the vise frame 1 is used in the example described above, a scale corresponding to the scale plate may be engraved on the side surface of the frame 1 instead. Although the fastening screw is used for fixing the scale plate, the scale plate may be fixed by adhesion, screws or rivets. When the scale plate is movable, it can be movably fixed by using a plate spring, a piston plunger, a rack or a magnet. Further, in order to position the scale plate, a protrusion or a concave stopper may be provided at an appropriate portion of the frame 1.

FIG. 5 shows an example in which the present invention is applied to a hydraulic vise for performing final tightening by hydraulic pressure. In this case, it is necessary to set a mouthpiece opening amount by opening a gap (t) smaller than a preset tightening stroke (T) for the work to be fastened. Therefore, by applying the present invention, the absolute value of the mouthpiece opening amount can be easily visually recognized, so that the movable jaw can be moved quickly to the set mouthpiece opening amount.
In addition, since the regular fastening stroke is secured, the fastening force is secured, and unexpected accidents do not occur. Therefore, by using the scale plate of the present invention, the safety of work is greatly improved.

FIG. 6 shows the vise according to the present invention applied to a two-piece fastening vise. In this case, since the scale plates are provided in accordance with the reference position of the central reference block 21, it is possible to easily confirm that the opening amounts of the left and right mouthpieces are slightly larger than the outer dimensions of the workpieces to be attached. , The work efficiency will be improved.

[0015]

According to the present invention, the operator can easily confirm the opening amount of the mouthpiece with the help of the scale plate. Even if the reference position of the base is changed, the reference position of the scale can be easily adjusted to the original position of the base by moving the scale in the fastening direction (horizontal direction in the illustrated example). Therefore, the operator can reliably and easily know the opening amount of the mouthpiece regardless of the specifications of the mouthpiece.

When the work is arranged on the stepped portion of the stepped die as shown in FIG. 4, the work is placed on the stepped portion of the die unless the opening amount of the die is set to an appropriate amount in advance. Difficult to place. Therefore, the fact that the opening amount of the mouthpiece can be easily confirmed with the help of the arrow not only improves the work efficiency, but also improves the safety of the setup work because the work does not drop from the step portion of the mouthpiece. You can do it.
