Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise device attached to a mortise machine.

[0002]

2. Description of the Related Art Conventionally, a vise device of this type is usually disclosed in, for example, Japanese Utility Model Publication No. 56-14972 or Japanese Utility Model Publication No.
As disclosed in Japanese Patent No. 45847 and the like, a pair of vise blocks for clamping a material are provided so as to be able to move forward and backward with respect to the mortising machine body.
The operation of opening and closing the pair of vise blocks to clamp and unclamp the material is performed by rotating the handle, while the operation of moving the vise block forward and backward is performed by a slide lever provided separately from the handle. It was configured by. Further, in order to fix the vice block at a predetermined position with respect to the mortise cutting machine main body, a fixing screw or the like provided separately is tightened.

[0003]

As described above, in the conventional vise apparatus, the operation of clamping / unclamping the material, or the operation of moving and fixing the vise apparatus are performed by the handles or levers provided separately. It is necessary to operate the levers etc. arranged around the vise device when setting the material, which makes the operation of the vise device very complicated, and the efficiency of the mortise cutting work. Was bad.

The present invention has been made in view of this problem.
It is an object of the present invention to provide a vise device that requires a small number of operation steps when setting a material for a mortise cutting machine body.

[0005]

Therefore, the invention according to claim 1 is a vise device comprising a pair of vise blocks for clamping a material on a frame which advances and retracts with respect to the mortise cutter body. A vise device for a tenon slicing machine is created, which is configured such that one frame can be operated by switching the forward / backward movement of the frame and the opening / closing of the vise block by operating a switching lever.

Further, in the invention described in claim 2, in addition to the configuration described in claim 1, when the switching lever is switched to the opening / closing operation side of the vise block, the movement of the frame is prevented. We have created a vice device for a tenon slicing machine.

[0007]

According to the structure of the first aspect, the function of the handle is switched by operating the switching lever. That is, when the switching lever is operated to one side, this handle becomes a handle for moving the frame in the front-back direction, and when operated to the other side, this handle becomes a handle for opening and closing the vise block. Therefore, one handle can be used for both forward and backward movements of the frame and opening and closing movements of the vise block.

According to the second aspect of the invention, in addition to the above operation, when the switching lever is switched to the opening / closing operation side of the vise block, the movement of the frame in the front-rear direction is locked at the same time. Therefore, each operation of moving the frame in the front-back direction, opening and closing the vice block, and locking the frame, which were conventionally operated by separately provided levers or handles, is performed by two switching levers and handles. Operation becomes possible, and the number of operations can be further simplified.

[0009]

Embodiments of the present invention will be described below with reference to FIGS. In the figure, 1 is a base of the vise device of this example, and two slide shafts 2 are provided in the base 1 in the front-rear direction (direction forward or backward with respect to the main body of the mortise machine, the same applies hereinafter). They are supported in parallel with each other, and through both slide shafts 2 and 2, the frame 3
Is supported so as to be able to move forward or backward with respect to the main body of the mortise cutter.

Supporting edges 3 are provided on both left and right sides of the frame 3.
a and 3a are provided in a rising shape, and two slide shafts 4 and 4 are parallel to each other and fixed between the support edges 3a and 3a, as shown in FIG. 2 or FIG. It is movably supported in the axial direction within the range. The left end portions of both slide shafts 4 and 4 are protruded leftward from the support edge 3a, and the both end portions of the slide shafts 4 and 4 are fixed to the connecting block 6 by the protruding tip end portions. A pair of vise blocks 5 and 5 are supported by both slide shafts 4 and 4 supported in this manner so as to face each other and be movable in the left-right direction.

Screw holes 5a, 5a are concentrically provided in the lower portions of both vise blocks 5, 5, and screw portions 7a, 7b of a screw shaft 7 are screwed into these screw holes 5a, 5a. ing. Both screw portions 7a and 7b of the screw shaft 7 are formed with the same lead and have mutually opposite threads. Therefore, when the screw shaft 7 is rotated clockwise, both vise blocks 5 and 5 move toward each other, and when the screw shaft 7 is rotated counterclockwise, they move away from each other. However, since the leads of both screw portions 7a and 7b are the same, the center between both vise blocks 5 and 5, that is, the clamp center of the material does not move. The movement of the clamp center of the material, that is, the centering of the vise apparatus is performed by the centering lever 8 described later.

This screw shaft 7 is also supported so as to be movable in a certain range in the axial direction with respect to both support edges 3a, 3a, and its left end portion is projected from the support edge 3a and is rotatably supported by the connecting block 6. Has been done. Therefore, the connection block 6
Is moved to the left and right, both slide shafts 4,
4 and the screw shaft 7 move, so that both vise blocks 5 and 5 integrally move in the left-right direction. By moving both vise blocks 5 and 5 as a unit, the clamp center of the material moves, and the vise device is centered.

The centering mechanism will be described below.
A plate 8a is attached to the left supporting edge 3a of the frame 3, and a centering lever 8 is rotatably attached to the plate 8a. As shown in FIG. 1, a shaft portion 8b having a smaller diameter is integrally formed at the tip of the centering lever 8 with a certain size eccentric. On the other hand, a long groove hole 6a is formed on the upper surface of the connecting block 6 along the longitudinal direction thereof, and the eccentric shaft portion 8b is inserted into the long groove hole 6a. Therefore, when the centering lever 8 is rotated about its axis, the eccentric shaft portion 8b moves about the axis of the centering lever 8, so that the connecting block 6 approaches or separates from the support edge 3a. Therefore, both slide shafts 4, 4, both vise blocks 5, 5 and the screw shaft 7 move integrally in the left-right direction as described above, whereby the clamp centers of both vise blocks 5, 5 are moved. Can be moved to center the vise device. Note that FIG.
Alternatively, as shown in FIG. 4, a fixing screw 9 is separately provided on the upper surface of the left side support edge 3a, and the fixing screw 9 is tightened and the tip portion thereof is pressed against the slide shaft 4 for connection. The block 6 is immovably fixed to the support edge 3a, whereby the center of the clamp can be fixed so as not to shift.

Next, the right end portion of the screw shaft 7 is also the frame 3
Is protruded from the support edge 3a on the right side of, and the handle 10 is attached to the protruding portion so as to be movable in the axial direction. A pin 11 is driven in the radial direction of the right end portion of the screw shaft 7 and is fixed in a state where both ends thereof are projected. On the other hand, on the right end surface of the boss portion 10a of the handle 10, grooves 10b, 10b are formed along the radial direction.
Therefore, the handle 10 is moved to the right and the groove 10
When the pin 11 is projected and both ends thereof are fitted into b and 10b, the handle 10 is rotationally connected to the screw shaft 7, and therefore, when the handle 10 is rotated, the screw shaft 7 also rotates integrally. On the contrary, move the handle 10 to the left and
When the protruding end of 1 is pulled out from the inside of the groove 10a, the handle 10 idles and the screw shaft 7 does not rotate.

On the other hand, a gear portion 10c is integrally formed at the left end of the boss portion 10a of the handle 10. On the other hand, a rack 12 is attached to the right side surface of the base 1 below the boss portion 10a along the front-rear direction, and when the handle 10 is moved leftward in the drawing, the gear portion 10c is moved. It is meshed with this rack 12. The rack 12 has a length from the front end to the rear end of the base 1 as shown in FIG. 5. Therefore, when the handle 10 is rotated with the gear portion 10c meshed with the rack 12, The frame 3 moves along the front-rear direction. In the state where the gear portion 10c meshes with the rack 12, the pin 11 is not fitted in the groove portion 10b, so the handle 1
0 idles with respect to the screw shaft 7, and therefore the vise blocks 5 and 5 are not opened or closed.

As described above, the handle 10 is movable in the axial direction on the tip end portion of the screw shaft 7 protruding from the screw shaft 7. The handle 10 is rotated with the pin 11 fitted in the groove portion 10b by moving it to the right. Then, the screw shaft 7 is rotated, whereby the vise blocks 5 and 5 are opened and closed. On the other hand, when the handle 10 is rotated leftward and the gear 10c is engaged with the rack 12 and the handle 10 is rotated, the frame 3 is moved back and forth, which causes the vice blocks 5, 5 to move.
The material fixed in between can be moved toward or away from the mortar body.

Next, a switching plate 13 is attached to the right side support edge 3a of the frame 3. The switching plate 13 has an overhanging edge 13a that overhangs the boss portion 10a of the handle 10 and a forked edge 13b that extends downward from the overhanging tip of the overhanging edge 13a and hangs downward. The switching edge 13c is provided so as to hang downward from the front side portion of 13a. Slots 13d and 13d are formed in the rear portion on the left side of the overhanging edge 13a in the figure, and both slots 13d and 13d are formed.
The bolts 13e and 13e are screwed onto the upper surface of the support edge 3a within a range in which the movement of the switching plate 13 is allowed via d, so that the switching plate 13 is movable in the left-right direction. Supported by.

The bifurcated edge 13b is arranged in a state of straddling the small diameter portion of the boss portion 10a, and the compression coil spring 14 having the same spring constant between the front and back surfaces of the bifurcated edge 13b and both side walls of the small diameter portion. , 15 are interposed. Therefore, when the switching plate 13 is moved in the left-right direction, the handle 10 moves in the axial direction of the screw shaft 7 almost integrally with the switching plate 13 by the urging force of the one compression coil spring 14 or 15. That is, when the switching plate 13 is moved to the right, the urging force of the compression coil spring 14 on the right moves the handle 10 to the right by substantially the same distance. Conversely, when the switching plate 13 is moved to the left, the compression on the left side is compressed. The urging force of the coil spring 15 moves the handle 10 leftward by substantially the same distance.

Next, the switching plate 13 has a switching groove 13f extending from the overhanging edge 13a to the switching edge 13c.
Are formed. The switching groove 13f is formed along a direction inclined at a constant angle with respect to the screw shaft 7 as shown in the drawing, that is, in a direction in which the switching groove 13f is swung to the right from the vertical line toward the lower end of the switching edge 13c. There is.

A switching lever 16 is provided in the switching groove 13f.
Has been inserted. The switching lever 16 is fixed to the tip of a support shaft 16a that is rotatable on the side of the frame 3 and is inserted and supported in parallel with the screw shaft 17. Therefore, the switching lever 16 is supported rotatably in the front-rear direction on the surface orthogonal to the screw shaft 7 about the support shaft 16a. Here, the switching lever 16 passes through the switching groove 13f as described above and then passes through the support shaft 16a.
Supported by. Therefore, when the switching lever 16 is rotated in the front-back direction, the switching lever 16 moves in the switching groove portion 13f, but the moving direction of the switching lever 16 and the extending direction of the switching groove 13f coincide with each other. Since the switching plate 13 does not exist, the switching plate 13 moves in the left-right direction as the switching lever 16 rotates.

That is, as shown by the solid lines in FIGS. 1, 2 and 5, when the switching lever 16 is pivoted forward to a substantially upright position, the switching plate 13 moves to the right, so that the handle 10 moves to the right. When the handle 11 and the screw shaft 7 are rotationally connected by this, the pin 11 is fitted into the groove 10b by moving the handle 10 toward the groove portion 10b, that is, the state in which the vice blocks 5 and 5 can be opened and closed by rotating the handle 10. Becomes Hereinafter, this state is referred to as a "vice block opening / closing operation state".

On the contrary, when the switching lever 16 is pivoted rearward (toward the front side) and tilted substantially horizontally as shown by the chain double-dashed line in FIGS. 3, 4 and 5, the switching plate 13 is leftward. Therefore, the handle 10 moves to the left and the gear portion 10c meshes with the rack 12, so that when the handle 10 is rotated, the frame 3 or the vice device can be moved in the front-rear direction. . Hereinafter, this state is referred to as a "vice movement operation state".

Next, a screw portion 16b is formed at the tip of the support shaft 16a on the insertion base side, and this screw portion 16b is screwed into the screw hole 3b of the frame 13. Since the screw hole 3b penetrates the support hole 3c into which the slide shaft 2 is inserted as shown in FIG. 1, when the support shaft 16a is rotated clockwise and the screw portion 16b is tightened, the screw portion 16b is tightened. The tip end of 16b is pressed by the slide shaft 2, so that the frame 3 cannot move in the front-rear direction. Conversely, when the support shaft 16a is rotated counterclockwise and the screw portion 16b is loosened, the screw portion 16b
Since the tip of b is separated from the slide shaft 2, the frame 3 can move in the front-rear direction. In this way, the support shaft 16a has a function as a stopper for locking or unlocking the movement of the frame 3 and thus the vice device in the front-rear direction by being rotated about the axis thereof in the range of approximately 90 °. The rotation of the support shaft 16a is performed by the rotation of the switching lever 16.

That is, when the switching lever 16 is raised and brought into the "vice block opening / closing operation state", the handle 10 and the screw shaft 7 are connected as described above, and at the same time, the support shaft 16a is rotated clockwise. Screw part 16
b is tightened and its tip is pressed against the slide shaft 2. Therefore, the frame 3 and thus the vise device are locked so that they cannot be moved forward and backward. If the handle 10 is rotated in this locked state, the vise block 5, The opening and closing operation of 5 can be performed.

On the other hand, when the switching lever 16 is tilted to the "vice moving operation state", the gear portion 10c of the handle 10 is
Is engaged with the rack 12 and at the same time, the support shaft 16a
Is rotated counterclockwise, the screw portion 16b is loosened and its tip is separated from the slide shaft 2, so that the frame 3 and thus the vise device are movable in the front-rear direction. In this state, the handle 10 can be rotated. For example, since the gear portion 10c rolls on the rack 12, the vise device can be moved in the front-rear direction.

In FIGS. 2 and 4, reference numerals 17 and 18 denote receiving bars for placing a material, and both receiving bars 17 and 18 are rotatably supported between both supporting edges 3a and 3a. There is. A rotary knob 19 is attached to the right end of the receiving bar 18 on the lower side of the drawing. By rotating the rotary knob 19, both receiving bars 17, 1
The material placed on 8 can be moved in the front-rear direction to be aligned with the vise blocks 5, 5.

Next, an operation procedure of the vise apparatus of the present example configured as described above will be described. First, FIG. 3 and FIG.
As shown in, the switching lever 16 is tilted substantially horizontally to be in the "vice moving operation state". In this state, the handle 10 moves to the left, the gear portion 10c meshes with the rack 12, and the tip of the screw portion 16b of the support shaft 16a is separated from the slide shaft 2. Next, the handle 10 is rotated counterclockwise to retract the vise device to the front side, and at the fully retracted position, the switching lever 16
Is set almost vertically to be in the "vice block opening / closing operation state". In this state, the handle 10 is moved leftward to be rotationally connected to the screw shaft 7, and the screw portion 16b of the support shaft 16a is tightened and pressed against the slide shaft 2, whereby the vise device is moved forward and backward. It is locked so that it does not move in the direction. In this state, the handle 10 is rotated counterclockwise to open the space between the two vise blocks 5 and 5 sufficiently, and then the material is placed between the two vise blocks 5 and 5. At this time, the rotary knob 19
Rotate to align the material in the front-back direction with respect to the vise device. After that, the handle 10 is rotated clockwise to close both the vise blocks 5 and 5 and sandwich and fix the material.

After fixing the material in this way, the switching lever 16 is tilted again to bring the vise device into the "vice moving operation state", and then the handle 10 is rotated clockwise to move the vise device to the mortise cutting machine body. It is moved toward and sets the material in place with respect to the mortise cutter body. At this time, if necessary, the centering lever 8 is rotated to center the material with respect to the main body of the mortise machine, and when the centering is completed, the fixing screw 9 is tightened to prevent center misalignment. The position of 5 in the left-right direction is fixed.

When the setting of the material is completed and the mortise cutting is completed for this material, the switching handle 16 is tilted again to be in the "vice moving operation state",
In this state, the handle 10 is rotated counterclockwise to retract the vise device. At a sufficiently retracted position, the switching handle 16 is set up to be in the "vice block opening / closing operation state", and then the handle 10 is rotated counterclockwise to open both vice blocks 5 and 5, and the processed material is removed from the vice device. Remove.

This example is constructed as described above,
With this structure, the handle 10 can be used by switching the vice block opening / closing and moving the vice device by simply operating the switching lever 16. Moreover,
Switching lever 1 to open and close the vice blocks 5 and 5
When 6 is set up, the threaded portion 16b of the support shaft 16a is tightened and pressed against the slide shaft 2, whereby the frame 3 is locked immovably.
As described above, the opening / closing operation of the vise blocks 5 and 5, the movement operation of the vise device in the front-rear direction, and the lock / unlock operation thereof can be achieved only by operating the handle 10 and the switching lever 16. It becomes possible to set the material with a smaller number of steps as compared with the configuration achieved by using separate levers or the like.

[0031]

According to the first aspect of the present invention, the movement of the frame and the opening and closing of the vise block can be operated with a single handle. The device can be operated and thus the efficiency of the mortise work can be increased.

According to the second aspect of the present invention, since the frame is locked and unlocked simultaneously with the switching operation of the switching lever, the operation can be further simplified.
