Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise, and in particular, fixed jaws and movable jaws provided on a vise body are provided with respective mouthpieces for providing a clamping surface for clamping a predetermined article so as to face each other. The present invention relates to an improved structure of the vice.

[0002]

BACKGROUND ART As is well known, a vise of this type is provided with two bases facing each other, which are attached to the movable jaw and the fixed jaw by moving the movable jaw closer to the fixed jaw. In between, a predetermined article (workpiece) is clamped and fixed. Generally, the clamping surfaces of the two caps are smooth surfaces that spread in a direction perpendicular to the opposing direction. Therefore, for example, the distance (for example, length or width) between the surfaces to be clamped (clamped surface)
It is not possible to simultaneously clamp two kinds of articles with different positions in parallel between the movable jaw and the fixed jaw, and the clamped surface of the article to be processed has, for example, low plane accuracy. Or a stepped surface or an inclined surface, that is, a shape different from the clamp surface of the mouthpiece, the contact area of each of the mouthpieces on the clamp surface of the clamped surface inevitably becomes small. However, it was difficult to perform stable clamping.

Under such circumstances, Japanese Patent Laid-Open No. 2001-23257.
In Japanese Patent Laid-Open No. 2 (1994), a plurality of plunger holes extending in the clamping direction of an article and a plurality of these plunger holes are communicated with each other in a mouthpiece main body attached to a fixed jaw or a movable jaw of a vise while being opened to the outside on a clamping surface. A connecting hole is provided for connecting the plungers, and the plunger is inserted into each of the plunger holes so as to be movable in the axial direction, with one end protruding outward from the opening in the clamping surface. A mouthpiece in which a transmission member including a ball and a roller is housed in the connecting hole so as to be movable in the extending direction of the connecting hole while being brought into contact with the end surface of each plunger on the insertion side into the plunger hole. Has been revealed.

In such a die, one of the plurality of plungers is pressed and is axially moved so that the protruding portion of the clamp surface from the opening of the plunger hole is pushed into the plunger hole. And accordingly, the transmission member in the connecting hole is moved in the extending direction of the connecting hole, and the pressing force to the plunger pushed into the plunger hole is transmitted to the other plunger through the transmitting member. By doing so, the protruding portion from the opening of the plunger hole in those other plungers is pushed out from within each plunger hole,
It can be moved in the axial direction.

Therefore, for example, in a vise in which the mouthpiece having such a structure is attached to the movable jaw, a predetermined article is clamped between the clamp surface on the movable jaw side and the clamp surface on the fixed jaw side. In this case, by adjusting the projecting position of the tip surface of each plunger on the clamp surface on the movable jaw side, two types of articles having different distances between the clamped surfaces can be clamped at the same time. It is possible to stably clamp an article or the like whose clamp surface has a shape different from the clamp surface of the die.

However, in the mouthpiece disclosed in the above publication, the transmission member for transmitting the pressing force applied to one plunger to the other plunger is composed of a plurality of members including balls and rollers. However, there was an inherent problem of reduced manufacturability and increased manufacturing cost due to an increase in the number of parts, and in addition, in the vise using this mouthpiece, balls and rollers in the transmission member are clamped when a predetermined article is clamped. However, since a large pressing force is transmitted in a state of being in point contact or line contact with other members, extremely large stress concentration occurs in such balls and rollers, and these balls and rollers are The rollers may become deformed, and if this happens, extra maintenance must be done to replace the deformed balls or rollers. Than it was Tsu.

On the other hand, similar to the mouthpiece disclosed in the above-mentioned publication, the mouthpiece body is provided with a plurality of plunger holes that are open to the outside on the clamp surface and a connecting hole that connects them in a communicating state. Plungers are inserted into the plunger holes so as to be movable in the axial direction, and, unlike the mouthpiece disclosed in the above publication, the plunger is actuated instead of the transmission member including the balls and rollers as described above. A vice having a structure in which a mouthpiece filled with oil is attached to a movable jaw or a fixed jaw is also generally known.

In such a vise, the pressing force exerted on one plunger is transmitted to the other plunger by the flow of the hydraulic oil in the connecting hole, so that the surface to be clamped is clamped. Two types of articles with different distances, articles with a clamped surface of a shape different from the clamp surface of each mouthpiece, etc. can be reliably and stably clamped between the mouthpieces of the movable jaw and the fixed jaw. It can be done.

However, in such a vise,
Although there is a seal between the outer peripheral surface of the plunger and the inner peripheral surface of the plunger hole, it is inevitable that the hydraulic oil slightly oozes out between them when the article is clamped. In order to ensure stable clamp operation for a long period of time, it was necessary to periodically perform maintenance for replenishing hydraulic oil. Further, in such a vise, since the seal between the outer peripheral surface of the plunger and the inner peripheral surface of the plunger hole is realized by mounting a seal member or the like on the outer peripheral surface of the plunger, the shaft of the plunger is In order to suppress wear of the seal member due to sliding contact with the inner peripheral surface of the plunger hole along with the movement in the direction as much as possible, the inner peripheral surface of the plunger hole has high dimensional accuracy and sufficient Plunger holes had to be drilled so as to have a small surface roughness, which resulted in reduced manufacturability and higher manufacturing costs.

[0010]

The present invention has been made in view of the circumstances as described above, and the problem to be solved is to provide two types of articles in which the distances between the clamped surfaces are different from each other. It is possible to clamp simultaneously, and a structure that can stably clamp an article having a clamped surface with a shape different from the clamping surface of each mouthpiece requires no maintenance and lowers manufacturability and raises manufacturing cost. It is to provide a vise that is advantageously realized by a structure capable of suppressing as much as possible.

[0011]

According to the present invention, in order to solve such a problem, a movable jaw is moved closer to a fixed jaw fixed to a vise main body, whereby the movable jaw and the fixed jaw are moved. Each attached,
In a vise that clamps and fixes a predetermined article between two bases facing each other,
(A) a first housing hole provided in at least one of the two caps so as to extend straight along a direction perpendicular to the opposing direction thereof; and (b) the first housing. In the mouthpiece provided with holes, at two positions separated by a predetermined distance in the extending direction of the first accommodating hole, they are provided so as to extend straight in the facing direction of the two mouthpieces, respectively. (C) the two second housing holes that are open to the outside on the clamp surface of the base provided with the first housing hole and that clamps the predetermined article while being communicated with the first housing hole; For the first receiving hole,
The rod-shaped member is slidably inserted in the extending direction, and both end portions are provided with first inclined surfaces that incline in mutually different opposite directions, and the first inclined surface is inserted into the first accommodation hole. Under the state, the two first inclined surfaces are positioned so as to incline toward both ends of the first accommodation hole from the clamp surface side of the mouthpiece to the opposite side, respectively. (D) Two pins, one end of which is inserted into each of the two second accommodating holes so as to be capable of projecting / retracting through an opening that is open to the outside on the clamp surface of the base. A second inclined surface corresponding to the first inclined surface of the first moving member is provided at the other end of the second moving member while being inserted into each second accommodation hole. Below, The second slanted surface is slidably contacted with the first slanted surface at both ends of the first moving member inserted into the first accommodating hole, and the two slanted surfaces are positioned. And a second inclined surface that is in contact with the first inclined surfaces at both ends of the slide bar with the retracting movement of the one side end of one of the two clamp pins. Slidably contacting each other to move the slide bar from one side of the two clamp pins to the other side in the first housing hole, and at the same time, to the one end of the other clamp pin. The gist of the present invention is a vise, which is characterized in that the part is configured to move in a protruding manner.

In short, in the vise according to the present invention, one of the two clamp pins is pressed,
When the one end of the one clamp pin is retracted and moved so as to be pushed into the second accommodation hole into which the one clamp pin is inserted, the pressing force applied to the one clamp pin causes the first accommodation hole. Is transmitted to the other clamp pin via the slide bar movably inserted in the extension direction, whereby the one end of the other clamp pin is inserted into the second clamp pin. From the opening on the side of the clamp surface in the accommodation hole, the one of the clamp pins is made to project and move so as to be pushed out by an amount corresponding to the retracted movement amount.

Therefore, in the vise according to the present invention as described above, for example, the mouthpiece attached to the movable jaw is provided with the first accommodating hole and the two second accommodating holes, and the slide bar is provided therein. And two clamp pins are inserted respectively, one of the two types of articles with different distances between the surfaces to be clamped is the one clamp protruding from the clamp surface on the movable jaw side. The pin is arranged between the tip surface of one end of the pin and the clamp surface of the fixed jaw, while another one of these two types of articles is attached to the tip surface of the one end of the other clamp pin. If the movable jaw is moved closer to the fixed jaw while it is placed between the clamp surface and the clamp surface on the fixed jaw side, the distance between the clamped surfaces will be different. The same kind of articles can be clamped at the same time and reliably, and one clamped surface has a shape different from that of the clamp surface on the movable jaw side. ,
Place the movable jaws on the fixed jaws in such a way that the two clamp pins are brought into contact with the tip surfaces of the ends on one side, respectively, while the other clamped surface is brought into contact with the clamp surface on the fixed jaw side. Such articles can be stably clamped by moving them closer to each other.

Further, in such a vise, the first and second accommodation holes are provided in only the mouthpiece attached to the fixed jaw, or both the movable jaw and the mouthpiece of the fixed jaw, and the first and second accommodation holes are slid therein. Even when the bar and the clamp pin are inserted, the distances between the clamped surfaces are different from each other, as in the case where the bar and the clamp pin are arranged only for the ferrule attached to the movable jaw. While different types of articles can be clamped at the same time,
An article having a clamped surface having a different shape from the clamp surface of each die can be stably clamped.

Moreover, in the vise according to the present invention, as described above, the member functioning as a transmission member for transmitting the pressing force applied to one clamp pin to the other clamp pin is in the first accommodation hole. In the above, since it is composed of a slide bar composed of one rod-shaped member that is movably inserted in its extending direction, for example, such a transmission member is composed of a plurality of members including balls and rollers. Compared with the conventional device, the number of parts can be advantageously reduced, and unlike the conventional device in which the role of the transmission member is exerted by the hydraulic oil, the leakage of the hydraulic oil is It is not necessary to attach a seal member to the outer peripheral surface of each crank pin for prevention, and therefore, in order to prevent the wear of such a seal member, it is natural that Each second receiving hole Pupin is inserted, it is not even necessary to drill with as much as possible small surface roughness and high dimensional accuracy.

Further, in such a vise, the second inclined surface of each clamp pin is in surface contact with the two first inclined surfaces provided at both ends of the slide bar, respectively. By being brought into sliding contact with each other, the pressing force applied to one clamp pin is transmitted to the other clamp pin via the slide bar, so that the transmission member does not contact the other member. Unlike the conventional device composed of a plurality of members including balls and rollers that are brought into contact or line contact, a slide bar that is a transmission member when transmitting the pressing force to one clamp pin to the other clamp pin. In the above, there is no large concentration of stress that causes it to be deformed, and the role of the transmission member is exhibited by the hydraulic oil. To the different from the conventional apparatus, the need to replenish the regular hydraulic oil is of no.

Therefore, in such a vise according to the present invention, by forming the first and second accommodation holes and disposing the clamp pin and the slide bar, it is possible to increase the number of parts and improve the processing precision more than necessary. It is possible to advantageously avoid a decrease in manufacturability of the mouthpiece, and hence the overall vise, and a rise in manufacturing cost, and it is possible to stabilize the mechanism for transmitting the pressing force to one clamp pin to the other clamp pin. The need for tedious maintenance to achieve this can be advantageously eliminated.

Therefore, in the vise according to the present invention as described above, it is possible to simultaneously clamp two types of articles having different distances between the surfaces to be clamped and a shape different from the clamping surface of each die. It is possible to stably clamp an article having a surface to be clamped, and the structure therefor does not require maintenance, and it is possible to suppress deterioration of manufacturability and soaring of manufacturing cost as much as possible. It can be advantageously realized by the structure.

According to one of the preferred embodiments of the vise according to the present invention, a seal ring is attached to the outer peripheral surface of each of the two clamp pins so that the outer periphery of each of the two clamp pins is attached. The surface and the inner peripheral surface of the second accommodating hole into which each of the clamp pins is inserted are sealed.

In the vise having such a structure, for example, foreign matter such as chips generated when cutting a predetermined article clamped between the movable jaw side and the fixed jaw side is clamped. From the opening of the second housing hole that opens to the outside on the surface, enter the second housing hole or the first housing hole, and hinder smooth movement of each clamp pin or slide bar. Can be advantageously avoided, whereby good usability can be stably ensured.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION In order to more specifically clarify the present invention, the structure of a vise according to the present invention will be described below.
A detailed description will be given with reference to the drawings.

First, FIGS. 1 and 2 schematically show a horizontal vise as an example of a vise having a structure according to the present invention in a top view and a vertical cross section. In these drawings, 10 is a vise body that is long in the horizontal direction, and a fixed jaw 12 having a block shape is integrally extended upwardly at one longitudinal end thereof, Two guide rails 14, 14 that are provided for position fixing and extend parallel to each other in the longitudinal direction are integrally formed at an upper portion other than the portion where the fixed jaw 12 is formed. In addition, the movable jaw 16 is attached to the vise body 10.
Are arranged facing the fixed jaw 12 in a state of straddling the two guide rails 14 and 14, and the movable jaw 16 has a well-known structure so that the two guide rails 1 are provided.
The guide jaws 4 and 14 can be moved toward and away from the fixed jaw 12.

That is, here, the male screw portion 1 is provided on the outer peripheral surface.
A longitudinal spindle 20 formed with 8 is immovably and rotatably supported between the two guide rails 14 and 14 so as to extend in the longitudinal direction of the vise body 10. There is. Further, a thick-walled cylindrical female screw member 24 having a female screw portion 22 formed on the inner peripheral surface thereof is externally inserted to the spindle 20 in a state where the female screw portion 22 is screwed onto the male screw portion 18. The movable jaw 16 is bolted to the female screw member 24 in a mounted state.

Thus, the movable jaw 16 is rotated by rotating the spindle 20 with a handle (not shown) or the like.
However, together with the female screw member 24, it can be moved toward and away from the fixed jaw 12 while sliding on the two guide rails 14 and 14 in accordance with the rotation direction of the spindle 20. Then, the fixed jaws 12 and the movable jaws 16 are respectively fixed to the facing surfaces of the fixed jaws 12 and the movable jaws 16 with bolts 26 and 27 made of a thick rectangular plate material, respectively, so that the movable jaws 16 move closer to the fixed jaws 12. Thus, a predetermined workpiece (not shown) is clamped and fixed between the clamping surfaces 28 and 29 of the two ferrules 26 and 27.

By the way, in the vise of the present embodiment having such a structure, of the two ferrules 26, 27 attached to the fixed jaw 12 and the movable jaw 16, the ferrule 27 attached to the movable jaw 16 is the one. , With a special structure not seen in the past.

That is, as shown in FIG. 3, in the mouthpiece 27 attached to the movable jaw 16, a circular first accommodating hole 30 which penetrates the mouthpiece 27 at a substantially middle portion in the thickness direction is formed in the fixed jaw 12. Mounted base 26
Of the first accommodating hole 3 is formed so as to extend straight in a horizontal direction perpendicular to the opposing direction of the clamping surface 28 and open laterally on both left and right side surfaces.
Two second accommodating holes 32a, 32b having a circular shape are provided at the left and right sides (the upper side and the lower side in FIG. 3) at a predetermined distance in the extending direction of 0 from the clamping surface 28 of the base 26. And the movable jaw 1 extending straight in the direction opposite to
The clamp surface 29 of the mouthpiece 27 attached to 6 is formed so as to open to the outside toward the clamp surface 28 of the mouthpiece 26 on the fixed jaw 12 side. Further, each of the two second housing holes 32a, 32b on the left and right has a depth reaching the vicinity of the back surface 36 on the side opposite to the clamp surface 29. In a state where it intersects the accommodation hole 30 at a right angle,
The first accommodating hole 30 is communicated with.

Here, while the slide pin 38 is inserted and arranged in such a first accommodating hole 30, inside the second accommodating hole 32a located on the left side (upper side in FIG. 3) and on the right side. The left clamp pin 40a and the right clamp pin 40b are respectively inserted and arranged in the second accommodation hole 32b located on the lower side (in FIG. 3).

More specifically, the slide pin 38 inserted and arranged in the first accommodation hole 30 is made of a cylindrical rod-shaped steel material and has an outer diameter slightly smaller than the inner diameter of the first accommodation hole 30. Since the first accommodating hole 30 has a length shorter than the entire length of the first accommodating hole 30, the first accommodating hole 30 can be slid in the extending direction. Further, the length of the slide pin 38 on the central axis is substantially the same as the distance between the central axes of the two second housing holes 32a and 32b. Furthermore, in the slide pin 38, the end surfaces on both sides have the same inclination angle (inclination angle with respect to the central axis) in different opposite directions.
The first inclined surfaces 42a and 42b are inclined.

The slide pin 38 is arranged in the first accommodation hole 30 so as to be slidably movable in the extending direction of the first accommodation hole 30, and in such an arrangement state. , Two first inclined surfaces 42a, 42 composed of both end surfaces at each of the intersections of the first accommodation hole 30 with the two second accommodation holes 32a, 32b.
b is the back surface 36 from the clamp surface 29 side of the base 27.
The second housing holes 30a and 32b, respectively, so as to incline toward both ends of the first housing hole 30, that is, to be arranged toward the opening portions of the second housing holes 32a and 32b, respectively. Is there.

On the other hand, the two left and right second accommodation holes 32a, 3
The left and right clamp pins 40a, 40b respectively inserted and arranged in 2b are made of a cylindrical pin-shaped steel material having the same size and shape, and each of the second accommodation holes 32a, 3
By having an outer diameter slightly smaller than the inner diameter of 2b and a length shorter than the total length of each of the second accommodation holes 32a, 32b, the inside of each of the second accommodation holes 32a, 32b is It is configured so that it can be moved in the extending direction. The length of each clamp pin 40a, 40b on the central axis is from the intersection of the second accommodation hole 32a, 32b with the first accommodation hole 30 to the opening of the clamp surface 29. It is made longer than the length by a predetermined dimension.

Further, the left and right clamp pins 4 are
0a, 40b, the second accommodation holes 32a, 32
The end face on the front side in the insertion direction into the inside of b is the slide pin 3
The second inclined surfaces 44a and 44b corresponding to the first inclined surfaces 42a and 42b in FIG. 6 are inclined at the same inclination angle (inclination angle with respect to the central axis).
On the other hand, the end faces on the opposite side to the holding faces 46a and 46b are smooth vertical faces.

Then, such two clamp pins 4
0a and 40b are second accommodation holes 32a and 32, respectively.
It is inserted and arranged in b so as to be slidable in the extending direction. Further, in such an arrangement state, the second inclined surfaces 44a, 44b are positioned at the intersections of the second accommodation holes 32a, 32b with the first accommodation holes 30, and the intersections Are slidably contacted with the respective first inclined surfaces 42a, 42b of the slide pin 36 arranged at the end, and the end portions on the opposite side to the formation side of the respective second inclined surfaces 44a, 44b. However, the base 2 attached to the fixed jaw 12 from the opening in the clamp surface 29 of each of the second accommodation holes 32a and 32b.
6 is made to project toward the clamp surface 28 side, and the holding surfaces 46a and 46b are exposed to the outside in a state of being opposed to the clamp surface 28 on the fixed jaw 12 side.

Thus, here, as indicated by the chain double-dashed line in FIG. 3, for example, the left clamp pin 40a is used.
When the holding surface 46a of the second clamp pin 40a is pressed, the left clamp pin 40a is slidably contacted with the first inclined surface 42a of the slide bar 38, which is in contact with the left inclined pin 44a, with the second inclined surface 44a. The slide bar 38 is moved so as to be pushed into the accommodation hole 32a, while the slide bar 38 is slidably contacted with the second inclined surface 44a of the clamp pin 40a with respect to the first inclined surface 42a. While being guided to the inner peripheral surface of the hole 30, the clamp pin 40
In the amount corresponding to the retracted movement amount of a, the inside of the first accommodation hole 30 can be slid from the left side clamp pin 40a side toward the right side clamp pin 40b side (lower side in FIG. 3). There is. Then, the first inclined surface 42b of the slide bar 38, which comes into contact with the second inclined surface 44b of the right clamp pin 40b as the slide bar 38 slides, moves relative to the second inclined surface 44b. The right clamp pin 40b is guided to the inner peripheral surface of the second accommodation hole 32b by an amount corresponding to the sliding movement amount of the slide bar 38, that is, the retracting movement amount of the left clamp pin 40a. At the same time, it is adapted to be projected and moved so as to be pushed out from the second accommodation hole 32b.

In short, in the vise of this embodiment, the left clamp pin 40a and the right clamp pin 40b are used.
When either one of them is pressed and it is pulled in and moved,
The pressing force is transmitted to the other of the two clamp pins 40a and 40b via the slide bar 38, whereby the other clamp pin 40 is applied.
However, it is designed so that it can be projected and moved.

In this embodiment, seal bolts 34 for closing the first accommodation hole 30 are attached to the openings at both ends of the first accommodation hole 30, and the clamp pins 40a and 40b are provided with outer peripheral surfaces thereof. O-rings 48 made of rubber, which seal between the inner peripheral surface of each of the second accommodation holes 30a and 30b, are respectively inserted, whereby the first inclined surfaces 42a and 42b of the slide pin 38 are respectively inserted.
And each second inclined surface 44 of each clamp pin 40a, 40b
The lubricant or the like adhered between the contact surfaces with a and 44b is used for the first accommodation hole 30 and the respective second accommodation holes 32a and 32b.
It is possible to prevent leakage from the opening portions of the first receiving hole 30 and the second receiving holes 32a and 32b, and at the same time, the respective receiving holes 30 from the opening portions of the first receiving hole 30 and the second receiving holes 32a and 32b. It is possible to prevent foreign matter from entering the inside of the housings 32 and 32.

When using the vise of the present embodiment having such a structure as described above to clamp two workpieces having different distances between the surfaces to be clamped, that is, different lengths, for example, First, as shown in FIG. 4, when the movable jaw 16 is sufficiently separated from the fixed jaw 12, two pieces having different lengths are provided between the fixed jaw 12 and the movable jaw 16. The workpieces 50 and 52 are aligned and positioned. At this time, it is preferable that the workpieces 50 and 52 bring the clamped surfaces 54 and 56 facing the fixed jaws 12 into contact with the clamped surfaces 28 of the ferrule 26 attached to the fixed jaws 12, respectively. It will be arranged in a state where it is positioned. In addition, the two clamp pins 40 projected from the clamp surface 29 of the mouthpiece 27 attached to the movable jaw 16
The protruding positions of a and 40b may be arbitrary positions.

Next, when the two workpieces 50 and 52 are arranged as described above, the spindle 20 is rotated to
As shown by the chain double-dashed line in FIG. 4, the movable jaw 16 is
The fixed jaws 12 are gradually moved closer to each other.

At this time, the left and right clamp pins 4 projected from the clamp surface 29 on the movable jaw 16 side.
0a and 40b, the clamping surface 46a of the left clamp pin 40a facing the clamped surface 58 of the workpiece 50 having the longer length facing the movable jaw 16 is clamped to the workpiece 50. When the movable jaw 16 is moved closer to the fixed jaw 14 from the state of being brought into contact with the surface 58, the holding surface 46a of the left clamp pin 40a is pressed by the workpiece 50 accordingly. The left clamp pin 40a is retracted and moved into the second housing hole 32a into which the left clamp pin 40a is inserted, and the pressing force applied to the left clamp pin 40a is transmitted to the right clamp pin 40b via the slide bar 38. Thus, the right clamp pin 40b is moved so as to project from the second accommodation hole 32b into which the right clamp pin 40b is inserted. See Figure 5).

Then, as shown in FIG. 5, the holding surfaces 46a and 46b of the left and right clamp pins 40a and 40b protruding from the clamp surface 29 of the mouthpiece 27 on the movable jaw 16 side have different lengths. Clamping surface 5 on the movable jaw 16 side of one workpiece 50, 52
By moving the movable jaw 16 closer to the fixed jaw 12 until it comes into contact with the Nos. 8 and 60, the workpiece 50 having the longer length is moved to the clamp surface 28 of the mouthpiece 26 on the fixed jaw 12 side. The jaw 16 is clamped between the clamping surface 29 of the mouthpiece 27 on the jaw 16 side and the holding surface 46a of the left side clamping pin 40a, and at the same time, the workpiece 52 having the shorter length is fixed to the fixed jaw 1
Clamping is performed between the clamp surface 28 of the mouthpiece 26 on the second side and the holding surface 46b of the right clamp pin 40b which is largely projected from the clamp surface 29 of the mouthpiece 27 on the movable jaw 16 side.

In this case, the holding surfaces 46a and 46b of either one of the left and right clamp pins 40a and 40b are used.
Until one of the clamp pins 40 is flush with the clamp surface 29 of the mouthpiece 27 on the movable jaw 16 side.
When the a and 40b are retracted and moved, the movable jaw 1
Clamping surface 46 of one of the other clamp pins 40a, 40b that is projected from the clamp surface 29 of the mouthpiece 27 on the 6 side.
The distance between a and 46b and the clamp surface 29 is the maximum stroke in the protrusion / retraction movement of the clamp pins 40a and 40b, but the two workpieces 5 having different lengths from each other.
If the difference in length between 0 and 52 is within such a maximum stroke, the two workpieces 50 and 52
However, the fixed jaw 12 and the movable jaw 16 can be simultaneously clamped.

Further, in the vise of this embodiment, although not shown, the clamped surface on the movable jaw 16 side of the workpiece to be clamped is the clamp surface 29 of the mouthpiece 27 attached to the movable jaw 16. Even if they have different shapes, if the holding surfaces 46a and 46b of the left and right clamp pins 40a and 40b whose protruding heights are changed are brought into contact with two points of the clamped surface, Such a workpiece is attached to each of the clamping surfaces 46.
It is possible to stably clamp between a and 46b and the clamp surface 28 on the fixed jaw 12 side.

As described above, in the vise according to the present embodiment, the left and right clamp pins 40a, 40b are interlocked with each other, and the mechanism for projecting / retracting movement is fully utilized. Surface 54-60
Two workpieces 50, each having a different distance between them,
52 can be simultaneously and reliably clamped, and a workpiece having a clamped surface having a different shape from the clamp surface 29 on the movable jaw 16 side can also be stably clamped.

Moreover, in such a vise, in order to interlock the left and right clamp pins 40a, 40b with each other to move the protrusions / retracts, the pressing force against one of the two clamp pins 40a, 40b is
Since the member that transmits to either of them is simply configured by the slide bar 38 made of a rod-shaped steel material that is slidably inserted into the first accommodation hole 30 and arranged. , For example, unlike a conventional vise in which such a transmission member is composed of a plurality of members including balls and rollers, or a conventional vise in which the role of the transmission member is exerted by hydraulic oil. It is possible to prevent a decrease in manufacturability and a rise in manufacturing cost due to an increase in the number of parts and an excessively high processing accuracy requirement.
In addition, the left and right clamp pins 40a and 40b are projected /
The need to perform maintenance for stabilizing the retracting movement mechanism can be advantageously eliminated.

Further, in the vise of this embodiment, the O-rings 48 are externally fitted to the respective clamp pins 40a and 40b, so that the first and second accommodation holes 3 are formed.
The leakage of lubricant from 0, 32 is prevented,
Since the entry of foreign matter into the first and second accommodation holes 30 and 32 is prevented, the workpiece clamped between the movable jaw 16 and the fixed jaw 12 leaks out. It can be advantageously prevented from being contaminated by the contaminated lubricant or the like, and, for example, the first and second accommodation holes 30, 32 for the chips and the like produced by cutting or the like for such a workpiece. Intrusion into the inside can be reliably prevented, and the first and second receiving holes 3
Slide bar 38 and clamp pins 40 within 0, 32
The smooth movement of a and 40b can be advantageously ensured, and as a result, good usability can be stably maintained.

The specific construction of the present invention has been described above in detail, but this is merely an example, and the present invention is not restricted by the above description.

For example, the slide bar 38 and the clamp pins 40a and 40b are rod-shaped members and pin-shaped members that can be axially movably inserted into the first and second receiving holes 30, 32a and 32b, respectively. The outer shape is not limited as long as it is made of Therefore, the slide bar 38 and each clamp pin 40a, 40b
Can be configured to have, for example, a prismatic shape or an elliptic cylindrical shape. Of course, in that case, the first and second accommodation holes 30, 32a, 32b are formed in a shape corresponding to the outer shapes of the slide bar 38 and the clamp pins 40a, 40b.

As described above, the slide bar 38 and each of the clamp pins 40a and 40b are formed in a prismatic shape or an elliptic cylindrical shape, and the first and second accommodation holes 30,

Rotation about the axis of 40b can advantageously be prevented. Thereby, the state where the second inclined surfaces 44a, 44b of the clamp pins 40a, 40b are slidably in contact with the first inclined surfaces 42a, 42b of the slide bar 38 is always stable. Therefore, the pressing force applied to either one of the left and right clamp pins 40a and 40b can be more reliably and stably transmitted to the other of them via the slide bar 38. , And the first and second receiving holes 30, 32a, 3
When inserting the slide bar 38 and the left and right clamp pins 40a, 40b into the 2b, the advantage that the above-mentioned contact state between the slide bar 38 and each clamp pin 40a, 40b can be obtained very easily is also obtained. It will be done.

Furthermore, the first and second accommodation holes 30, 32
Slide bar 38 and each clamp pin 4 in a and 32b
In order to prevent the rotation of 0a and 40b around the axis,
For example, the slide bar 38 and the clamp pins 40a, 4
0b is provided with an appropriate engaging convex portion or engaging concave portion on the outer peripheral surface thereof, while the first and second accommodating holes 30, 32 are provided.
Slide bar 3 is attached to the inner peripheral surface of each of a and 32.
It is also possible to provide an engaging concave portion or an engaging convex portion that engages in the circumferential direction with respect to the engaging convex portion or the engaging concave portion provided on the outer peripheral surface of 8 and each clamp pin 40a, 40b. Also by this, the above-mentioned effects can be effectively enjoyed.

Further, the first accommodating hole 30 is provided with the movable jaw 1
The jaw 27 attached to the fixed jaw 12
Even if the slide bar 38 is formed so as to extend in the vertical direction orthogonal to the direction opposite to, or diagonally in the vertical direction, and the slide bar 38 is slidably inserted and arranged in such a first accommodating hole 30, no matter what. It doesn't matter. In that case, the two clamp pins 40a and 40b are attached to the clamp surface 2 of the base 27.
In FIG. 9, they are arranged at a predetermined distance in the vertical direction or the diagonal vertical direction.

Further, a plurality of first accommodating holes 30 may be provided in the mouthpiece 27 attached to the movable jaw 16, and one slide bar 38 may be inserted and arranged in each of the first accommodating holes 30. In that case, clamp pin 40
The pairs a and 40b are arranged in a set of two in a number corresponding to the number of slide bars 38 arranged.

Furthermore, in the above-mentioned embodiment, the entire surfaces of both end surfaces of the slide bar 38 and the clamp pins 40a, 40 are formed.
Although the entire one end surface of b is the first inclined surface 42 and the second inclined surface 44, respectively, the first inclined surface 42 and the second inclined surface are part of the end surfaces. Of course, it is also possible to form 44.

The slide bar 38 and the clamp pins 40a and 40b may be divided into a plurality of parts in the respective length directions. By doing so, the first accommodation hole 30 and the second accommodation holes 32a, 32b
However, even if it is formed with a slight bend, the bend is advantageously absorbed in the divided portions, and the slide bar 38 and the first and second receiving holes 30, 32a, 32b of the clamp pins 40a, 40b are accommodated. A stable movement in the axial direction can be secured.

Further, in the above embodiment, the first and second receiving holes 30, 32a, 32b are provided, and the slide bar 38 and the clamp pins 40a, 40 are provided therein.
Although the base 27 having a special structure in which b is inserted is directly attached to the movable jaw 16, such a special base is attached to, for example, a base of a conventionally known structure attached to the movable jaw. It is of course possible to attach the base 27 having a special structure indirectly (via the base having a conventionally known structure) to the movable jaw by fixing the base 27 to the movable jaw with a bolt or the like.

Furthermore, it is possible to attach the mouthpiece having such a special structure only to the fixed jaw 12 or to both the movable jaw 16 and the fixed jaw 12.

In addition, in the above-described embodiment, a specific example of applying the present invention to a horizontal vise configured so that the movable jaw can be moved toward and away from the fixed jaw in the horizontal direction is shown. However, according to the present invention, in addition, the movable jaw is moved vertically closer to the fixed jaw.
Needless to say, the present invention can also be advantageously applied to a vertical vise configured to be moved apart.

Although not listed one by one, the present invention
It can be carried out in an embodiment in which various changes, modifications, improvements, etc. are added based on the knowledge of those skilled in the art, and such an embodiment does not depart from the gist of the present invention.
Both are included within the scope of the present invention,
