Guide bars 76 and 86 are provided on the vise bases 71 and 81 to support the a and 72b and the vise pieces 82a and 82b, respectively.

Wood W fixed by vertical vise 60
A cutter 59 is located above one or the wood W2 fixed by the lateral vise 70,80. As the cutter 59 moves toward the woods W1 and W2, a cutting operation is performed, and a tenon 55 as shown in FIG.
A mortise 56 is formed. The cutter 59 shown in FIG. 10 has a dovetailed tenon 55 and a tenon hole 5 shown in FIGS. 9C and 9D.
6 to form a cutter.

In order to increase the processing accuracy, it is desirable that the vertical vise 60 and the horizontal vise 70, 80 hold the wood W1, W2 at a position as close to the cutter 59 as possible. By holding the woods W1 and W2 at a position close to the cutter 59, warpage of the woods W1 and W2 during cutting can be suppressed. For this reason, as shown in FIG.
0, the horizontal vise 70, 80 are arranged close to each other.

In order to hold the wood W1 in an appropriate orientation with respect to the cutter 59, the vertical vice 60
The opening and closing directions of the 2a and 62b (that is, the arrangement direction of the vise screws 63) must be perpendicular to the cutter center line L1 of the cutter 59. Further, in order to hold the wood W2 in an appropriate direction with respect to the cutter 59, the horizontal vise 7
At 0 and 80, vice pieces 72a, 72b, 82a,
The opening / closing direction of 82b (that is, the arrangement direction of the vise screws 73 and 83) must be parallel to the cutter center line L1 of the cutter 59.

When the opening and closing directions of the vice pieces are shifted,
The woods W1, W2 are fixed to the cutter 59 in an obliquely distorted state, and the processing accuracy is reduced. For this reason, in the assembling work of the vise device of the processing machine, the position of the vise piece in the opening and closing direction is precisely adjusted.

When performing special processing, the position of the wood W1 itself with respect to the cutter 59 may be moved. For example, when the tip of the wood W1 is warped and bent, the wood W1 is moved in the direction of the arrow 101 or 102 while being held between the vice pieces 62a and 62b, and the wood center line L2 at the tip of the wood W1 is cut. It is necessary to match the center line L1.

Even if the wood W1 is not warped, special processing for forming a tenon 55 or a tenon hole 56 (FIG. 9) at a position shifted from the wood center line L2 of the wood W1 is similarly performed. The wood W1 is moved between the cutter center line L1 and the wood center line L2 while being held between the vice pieces 62a and 62b while holding the wood W1.
Is positioned in a shifted state.

Here, when the wood W1 is moved in the directions of arrows 101 and 102, the direction of movement is as follows.
Similar to the opening / closing direction of 2b, the cutter center line L1 (FIG. 10)
Must be perpendicular to Assuming that the moving direction of the wood W1 in the directions of the arrows 101 and 102 is the cutter center line L
If it is not perpendicular to 1, the positional relationship between the tip line of the wood W1 and the cutter 59 will be deviated, and the processing accuracy will be degraded. Therefore, the moving direction of the wood W1 needs to be precisely aligned with the cutter center line L1 (FIG. 10).

[First Prior Art] FIG. 11 is a front view of a vice device according to a first prior art. As shown in FIG. 11, the vise base 61 is provided so as to rest on the bed 11. A sliding portion (not shown) is provided between the vise base 61 and the bed 11.
The vise base 61 is movable along the sliding portion on the bed 11 in the directions of arrows 101 and 102.

The vise screw 63 is rotated by operating the opening / closing handle 67H, the vise pieces 62a and 62b are closed, and the wood W1 is sandwiched and fixed. Thereafter, when the position of the wood center line L2 of the wood W1 is moved, the core moving handle 64 is rotated. The center moving handle 64 is a center moving shaft 64.
J, the center moving shaft 64J penetrates the bed wall 65 of the bed 11. The center moving shaft 64J is rotatable with respect to the bed wall 65, and does not move in the axial direction.

A screw portion is formed on the core moving shaft 64J, and is screwed into a screw hole formed in the vise base 61. That is, in response to the rotation operation of the lead moving handle 64, the vise base 61 moves on the bed 11 by arrows 101,

When the opening / closing handle 67H is rotated, the vice pieces 62a and 62b are closed by the rotation of the vise screw 63, and the wood W1 is sandwiched and fixed. After this, wood W
When moving the position of the first wood center line L2, the core moving handle 90 is rotated.

As a result, the cylindrical portion 90T screwed into the vise base 61 moves in the direction of the arrow 101 or 102. Since the vise screw 63 is supported by the cylindrical portion 90T so as not to move in the axial direction, the vise screw 63 is kept in a state where the interval between the vice pieces 62a and 62b is maintained.
It moves in the direction of arrow 101 or 102 integrally with cylindrical part 90T.

[Third Prior Art] Next, Japanese Utility Model Laid-Open No. 555-1
FIG. 13 and FIG. 14 show a work material clamping apparatus for a woodworking machine disclosed in Japanese Patent No. 51432 as a third prior art.
Shown in FIG. 13 is a partial plan sectional view of the vertical vise 60, and FIG. 14 is a rear view of the vertical vise 60 as viewed from the cutter 59 (FIG. 10). In the third prior art, similarly to the second prior art shown in FIG. 12, a core moving handle 92 is provided coaxially with the vise screw 63.

The vice screw 63 is located in the boss 96 of the vise base 61 in a state of being penetrated. Vise screw 63
Are freely supported in both the rotation direction and the axial direction with respect to the vise base 61 and the boss 96. A screw portion 97 is provided on the outer periphery of the boss 96, and a screw cylinder 94 is screwed into the screw portion 97.

When the core moving handle 92 is rotated, the screw cylinder 94 is integrally rotated. A connecting plate 95 is connected to the screw cylinder 94.
The connecting plate 95 is rotatable with respect to the screw cylinder 94 and does not move in the axial direction. In addition, screw cylinder 9
4 is provided with a vice screw 63 therethrough. The vise screw 63 is also rotatable with respect to the screw cylinder 94 and does not move in the axial direction.

Two guide bars 93 are integrally fixed to both ends of the connecting plate 95 by bolts. The two guide bars 93 penetrate through holes formed in the vise base 61 and are movable in the axial direction with respect to the vise base 61. Note that the feed roller 98 is used to set the cutter 59 when the wood W1 is set in the vertical vise 60.
This is a roller for smoothly feeding the wood W1 toward.

The open / close handle 67H is rotated to close the vise pieces 62a and 62b, and sandwich and fix the wood W1. Thereafter, when the position of the wood center line L2 (FIG. 10) of the wood W1 is moved, the core moving handle 92 is rotated. As a result, the screw cylinder 94 becomes the screw portion 97 of the boss 96.
It rotates upward and moves in the direction of arrow 101 or 102.

When the screw cylinder 94 moves in the direction of the arrow 101 or 102, the vice screw 63 also moves integrally, and the vice pieces 62a and 62b move in the direction of the arrow 101 or 102 while holding the wood W1. . At this time, the two guide bars 93 fixed to the connecting plate 95
Also slides with respect to the vise base 61, and the arrow 1
Move in 01 or 102 direction.

[0031]

The above prior arts have the following problems. First, in the first prior art shown in FIG. 11, it is necessary to provide a sliding portion between the vise base 61 and the bed 11, and there is a problem that the configuration of the vise device is complicated.

The core moving handle 64 for moving the vise base 61 serving as a base for the vise pieces 62a and 62b is located below the opening and closing handle 67H for opening and closing the vise pieces 62a and 62b. As described above, since the vertical vise 60 and the horizontal vise 70, 80 are arranged close to each other and the working space is limited (see FIG. 10), the center moving handle 64 provided below the opening / closing handle 67H. There is a problem that the operability is poor when operating.

Further, in the first prior art, the center moving shaft 64
By screwing J into the vise base 61,
The vise base 61 is moved in the direction of the arrow 101 or 102. As described above, the moving direction of the wood W1 needs to be precisely aligned in the vertical direction with respect to the cutter center line L1, similarly to the opening and closing directions of the vice pieces 62a and 62b. For this reason, in the first prior art, the vise piece 62
It is necessary to precisely adjust the moving direction of the vise base 61 in addition to the opening and closing directions of the a and 62b (the arrangement direction of the vise screw 63), and there is a problem in that assembling the vise device takes time.

On the other hand, in the second prior art shown in FIG. 12, a moving line for moving the vice screw 63 and the wood center line L2 of the wood W1 is provided concentrically, and the vice screw 63 itself is provided. Are in the axial direction (arrows 101 and 102).
Direction) to move the position of the wood W1. For this reason, the opening / closing direction of the vice pieces 62a and 62b in the directions of the arrows 101 and 102 (the direction in which the vise screws 63 are arranged) is simply aligned perpendicularly to the cutter center line L1, and at the same time, the moving direction of the wood W1 is also the center of the cutter. It can be set perpendicular to the line L1.

Therefore, it is not necessary to adjust the moving direction of the vise base 61 separately from the opening and closing directions of the vice pieces 62a and 62b, and the problem unlike the first prior art does not occur. Further, since the position of the opening / closing handle 67H and the position of the center moving handle 90 are also the same, the operability does not decrease.

However, the second prior art has the following problems. When the wood W1 is moved in the directions of the arrows 101 and 102, the vice screw 63 itself moves.
The position of the opening / closing handle 67H changes. When the position of the wood W1 is moved to perform special processing as described above,
Since the opening / closing handle 67H is located at a different place from the normal state, the operability is reduced.

In addition, it is necessary to secure a space so that the opening / closing handle 67H can move, which is an obstacle to downsizing the processing machine. Further, when the vertical vise 60 is provided apart from the cutter 59 in order to secure a space for moving the opening / closing handle 67H (see FIG. 10), the processing accuracy is affected by the warpage of the wood W1 during cutting. Is also reduced.

When the wood W1 is sandwiched between the vice pieces 62a and 62b, the vise pieces 62a and 62b are warped outward due to the pressing force of the sandwiching. And
A load may be generated between the vise pieces 62a and 62b and the two guide bars 66. Even if the core moving handle 90 is rotated in such a state, the vise pieces 62a, 62
b does not slide smoothly.
There is a problem that the movement cannot be easily adjusted in the 02 direction.

On the other hand, the third type shown in FIGS.
In the prior art, the guide bar 93 is movable with respect to the vise base 61, and the guide bar 93 also moves in the directions of arrows 101 and 102 integrally with the vise screw 63 and the vise pieces 62a and 62b. Therefore, the wood W1 can be smoothly moved in the direction of the arrow 101 or 102 without being affected by the load between the guide bar 93 and the vise pieces 62a and 62b.

However, the third prior art has the following problems. The two guide bars 93 are for the vise base 6
1 protrudes in the directions of arrows 101 and 102. For this reason,
On both sides of the vise base 61, the guide bars 93
A space must be secured for projecting the processing machine, which is an obstacle to downsizing the processing machine.

It is assumed that a rotating shaft for operating the opening / closing handle 67H is provided on the vise base 61 separately from the vise screw 63 so that the position of the opening / closing handle 67H is unchanged, and this rotating shaft is connected to the vice screw 63 by a chain or the like. Also, a collision between the opening / closing handle 67H and the protruding guide bar 93 occurs.

Further, similarly to the second prior art, it is necessary to secure a space so that the opening / closing handle 67H can move, which is an obstacle to downsizing the processing machine. Further, when the vertical vise 60 is provided apart from the cutter 59 in order to secure a space for moving the opening / closing handle 67H (see FIG. 10), the processing accuracy is affected by the warpage of the wood W1 during cutting. Is also reduced.

Therefore, the present invention has a simple configuration, can be miniaturized, is excellent in operability, does not require much time for adjustment at the time of assembling, and furthermore, it is possible to use wood (processing object). An object of the present invention is to provide a vice device of a processing machine that can smoothly move wood while holding the wood.

[0044]

According to a first aspect of the present invention, there is provided a vice device for a processing machine, comprising two holding pieces for sandwiching and holding an object to be processed mounted on a vise table of the processing machine, Two holding pieces movable in a closing direction for holding the processing target or an opening direction for releasing the holding of the processing target, a fixed guide fixed to the vise table, and movably attached to the fixed guide. Moving guide part,
A moving guide portion to which two holding pieces are slidably mounted, the two holding pieces slide in the closing direction or the opening direction by sliding with respect to the moving guide portion, and the moving guide portion is It is characterized in that it can be moved within the range of the fixed guide while keeping the distance between the two holding pieces.

A vice device for a processing machine according to a second aspect is the vise device for a processing machine according to the first aspect, wherein the moving guide portion is formed of a hollow member, and the hollow portion of the moving guide portion is fixed to the fixed guide portion. Is penetrated.

According to a third aspect of the present invention, there is provided a vice device for a processing machine, comprising two holding pieces for sandwiching and holding a processing object to be mounted on a vise table of the processing machine. Two holding pieces that can be moved in the opening direction to release the holding of the processing object, or two opening and closing shafts provided with the two holding pieces, and two holding pieces by rotating about the opening / closing axis center line. An opening / closing shaft for moving the opening / closing direction or the opening direction, rotatably attached to the vise table, a connection portion to which the opening / closing axis is connected, rotatably attached to the vice table, and an operation handle provided. An operating shaft for transmitting rotation to the connecting portion through the transmitting member, wherein the opening / closing shaft rotates according to the rotation of the connecting portion, and the opening / closing shaft is independent of the connecting portion, Line direction Is movable, provided with an axial movement control unit for moving the control shaft in the opening and closing shaft center line direction,
It is characterized by:

According to a fourth aspect of the present invention, there is provided a vice device for a processing machine, wherein the opening and closing shaft is connected to the axial movement control unit, and the axial movement control unit is provided with a vice device. By being screwed into the base, the shaft is moved in the axial direction according to the rotation, and the opening / closing shaft is moved in the direction of the center line of the opening / closing shaft.

A movement amount scale indicating a relative movement amount between the axial movement control unit and the vise table, and an operation handle, an axial movement control unit, a lock unit, and a movement amount scale are provided.
It is provided on one side of the vise stand, and is located along substantially the same horizontal line in the vise stand,
It is characterized by:

[0049]

According to the vice device of the processing machine according to the first aspect, the two holding pieces slide in the closing direction or the opening direction by sliding with respect to the moving guide portion. The moving guide is movable within the range of the fixed guide while maintaining the distance between the two holding pieces.

As described above, since the moving guide portion is movable with respect to the fixed guide portion, the object can be moved while the object is held by the two holding pieces. In addition, even when the two holding pieces sandwich the object to be processed, the smooth sliding between the two holding pieces and the moving guide part is lost, the moving guide part is moved with respect to the fixed guide part. By moving, the two holding pieces can move smoothly along the fixed guide portion while holding the object to be processed. That is, the processing target can be smoothly moved while the processing target is held by the two holding pieces.

Further, since the movable guide is movable within the range of the fixed guide, the movable guide does not protrude from the fixed guide when the position of the object to be processed is adjusted. Therefore, there is no obstacle to downsizing the processing machine.

In the vice device for a processing machine according to the second aspect, the moving guide portion is constituted by a hollow member.
A fixed guide penetrates the hollow portion of the moving guide. Therefore, the smooth movement of the moving guide portion with respect to the fixed guide portion can be reliably realized with a simple configuration.

In the vise apparatus for a processing machine according to the third aspect, the opening / closing axis can be moved in the center line direction of the opening / closing axis independently of the connection section by the axial movement control section. Thus, since the opening / closing axis moves in the direction of the center line of the opening / closing axis, the processing target can be moved while the processing target is held by the two holding pieces.

In addition, since the opening / closing axis itself moves and adjusts the position of the processing object, the opening / closing movement direction of the two holding pieces and the moving direction of the processing object coincide with each other. It is not necessary to separately adjust the moving direction of the processing object. For this reason, the adjustment at the time of assembly does not take much time.

Further, since an operation shaft provided with an operation handle is provided separately from the opening / closing shaft movable in the direction of the center line of the opening / closing shaft, the opening / closing shaft can be moved with respect to the vise table and the vice table can be moved. It is possible to make the positional relationship with the operation handle unchanged. Therefore, operability can be improved.

Further, since the opening / closing shaft rotates according to the rotation of the connecting portion, the opening / closing shaft rotates by receiving the rotation of the operating shaft via the transmission member, so that the two holding pieces can be reliably opened and closed.

In the vise apparatus for a processing machine according to the fourth aspect, an opening / closing axis is connected to the axial movement control section.
The axial movement control unit, which is screwed into the vise table, moves in the axial direction according to the rotation, and moves the opening / closing axis in the direction of the center axis of the opening / closing axis. Therefore, the opening / closing shaft can be reliably moved in the opening / closing shaft centerline direction by a desired length by the axial movement control section.

In the vise apparatus for a processing machine according to the fifth aspect, the operation handle, the axial movement control section, the lock section, and the movement amount scale are provided on one side of the vise table, and are substantially provided on the vise table. They are located along the same horizontal line. Therefore, operability can be improved.
