Description

  The present invention relates to a plurality of clamp mechanisms, and more particularly to a one-touch multiple clamp operation device that operates a plurality of clamp mechanisms by one touch that simultaneously operates a plurality of clamp mechanisms by a one-touch operation.

  As a conventional clamp mechanism, there is a clamp mechanism for fixing an object to be fixed described in Patent Document 1. The clamp mechanism includes a base, a pressing part that presses the object to be fixed, an operating part that is operated by hand, a pressing position that is attached to the base and the pressing part presses the fixed object, and A transmission body that transmits the movement of the operation portion to the presser portion so as to move between a standby position where the workpiece is held away from the object to be fixed, and the base moves a first opposing portion of the transmission body. A second opposing portion that faces the first opposing portion in a direction orthogonal to the direction, and the one opposing portion between the first opposing portion and the second opposing portion includes the one opposing portion to the other. An indenter that is elastically biased in a direction toward the opposite portion of the second member, a pressure surface that is pressed by the indenter is provided on the other opposite portion, and the presser portion is positioned at the pushing position on the pressure surface. The first indentation into which the indenter tries to enter Is, that the force the indenter into the first recess to the point of entering the first opposing section receives, in which the pressing part is urged to the side pushing the object to be fixed.

  According to this clamp mechanism, when the object to be fixed is fixed, after the object to be fixed is arranged at the fixing position, the operation unit is operated, and the presser part is moved from the standby position to the pressing position through the transmission body. At this pushing position, the first opposing portion of the transmission body receives a force that the indenter that is elastically biased enters the first concave portion provided in the pressure-receiving surface, and the pressing portion is applied to the side that presses the fixed object. Be forced. Therefore, the presser part presses the fixed object by the biased force, so that the fixed object can be fixed.

  Patent Document 2 discloses a toggle clamp including a base member, a clamp arm, and an operation lever. The clamp arm includes an output rod extending substantially perpendicularly from the clamp arm at one end and a base at the other end. A toggle mechanism is connected to the member, and the operation lever is formed such that one end thereof can be gripped and is connected to the base member and the clamp arm on the other end side via at least one link mechanism. The clamp arm is rotated by the rotation of the operation lever, and a clamp position where the article can be clamped and a release position where the clamp is released are switchable, and the output rod is clamped It has a contact part that contacts the article via a spring member that expands and contracts in the direction, and adjusts the amount of compression of the spring member during clamping Is the ability ones.

According to Patent Document 2, the clamping pressure can be set to a desired value by adjusting the compression amount at the time of clamping the spring member. In particular, the force (pressure) applied by the spring is determined by the spring constant and the compression amount ( The amount of pressure applied by the spring is proportional to the amount of compression. For this reason, compared with the case where the pressure is adjusted by adjusting the position of the contact portion with the conventional toggle clamp, the adjustment allowance is amplified.
Therefore, by adjusting the compression amount, the pressure can be precisely adjusted in smaller units, and fine adjustment is also easy. Moreover, various clamping pressures can be achieved depending on the spring constant of the spring member used. Therefore, in this toggle clamp, the clamp pressure can be adjusted easily and more precisely, and the thickness error of the article, for example, the positional deviation can be absorbed by the compression of the spring member and the clamp can be clamped.

  According to Patent Document 3, the toggle clamp is configured such that a pressing member capable of pressing a workpiece and an operation lever that performs a pressing operation and a pressing release operation of the pressing member by a swinging operation are connected by a toggle mechanism. Of the shafts of the supporting shaft portion of the link constituting the toggle mechanism, the shaft farthest in the direction opposite to the pressing direction of the toggle mechanism is the position at the time of completion of the pressing operation in the link connected by the shaft. A holding rod that is slidably disposed in a long hole provided in one of the two members connected by the shaft so as to substantially follow the longitudinal direction, and extends in the longitudinal direction of the long hole. The end of the holding rod and the other member of the two members connected by the shaft are connected by screw means having a turning knob, and the shaft is turned by rotating the turning knob. Is relatively adjusted within the slot. Those that are configured.

  As described above, the clamping mechanisms disclosed in Patent Documents 1 to 3 individually clamp the workpiece or release it. However, depending on the type of workpiece, if the clamps are individually removed, the workpiece may be cracked or damaged. Further, in the case of individual clamping, a technique such as setting the clamping position to a diagonal line or one jump is necessary. In addition, the work set and its clamping and unclamping require a considerable amount of time even for an experienced operator using nerves.

  Therefore, the present invention provides a one-touch multiple clamp operation device that performs a plurality of clamp mechanisms with a single control, can individually set each clamp or clamp release, and can arbitrarily select the type of each clamp mechanism. Providing is an issue.

  The one-touch multiple clamp operating device according to the invention of claim 1 is provided with an operation clamp that reciprocates an operating rod, a base that allows the operating rod to reciprocate, an attachment to the operating rod, and the base A plate provided with a spring biased between, a movable non-expandable fixed tube, a movable wire that moves relative to the fixed tube in a length direction inserted through the fixed tube, and the One end of either the fixed tube or the movable wire is attached to the plate, the other end of the fixed tube or the movable wire is attached to the base, and either one of the fixed tube or the movable wire is attached. The end of the movable part of the specific clamp mechanism and the other end of the fixed tube or the movable wire of the specific clamp mechanism Those attached to semi-fixed part.

Here, the operation clamp that reciprocates the operating rod may be any one that can stably stop at at least two positions, and may be one that can stably stop at three or more positions. The stable stop means that the stop state can be maintained even if the external force is released. The operating rod can be used as a combination of a cylinder such as a piston, a triangular column, a quadrangular column, a hexagonal column, and an L bracket.
Further, the base to which the operation clamp is attached and allows the reciprocating motion of the operating rod is the base on which the operating clamp is attached and the operating rod is reciprocated.
The plate attached to the operating rod is provided with a spring biased between the plate and the base, and the spring can return to its original stop position. Good.
Further, the movable tube that does not expand and contract and the movable wire that is inserted through the fixed tube and moves relative to each other do not change in length due to an external force, and the relative movement between the two is the same at one end and the other end. It is. In addition, the configuration in which one end of the fixed tube or the movable wire of the clamp mechanism is attached to the movable portion, and the other end of the fixed tube or the movable wire is attached to the reference fixed portion, Rather, the connection of the fixed tube or the movable wire of the operation input is specified.
In addition, the clamp mechanism includes a movable part that connects one end of the fixed tube or the movable wire, and a reference fixed part that connects the other end of the fixed tube or the movable wire. What is necessary is just to be able to perform clamping and unclamping based on the displacement applied between the movable part and the reference fixing part.

The fixed tube or the movable wire of the one-touch multiple clamp operation device according to the invention of claim 2 is provided with an adjusting portion for adjusting the length at least at one end.
Here, in the case where an adjustment unit for adjusting the length is provided at one end of the fixed tube or the movable wire, the relative operation distance between the fixed tube and the movable wire can be adjusted. Subtle adjustments are possible.

The plate attached to the operating rod of the one-touch multiple clamp operating device according to the invention of claim 3 is provided with an adjusting portion in which the connection position of the plate attached to the operating rod can be adjusted.
Here, the connection position of the plate attached to the operating rod is adjustable, which means that the operation of all the clamp mechanisms can be adjusted at the same time without adjusting the movable part and the reference fixing part of each clamp mechanism. It is.

The spring urged between the base and the plate of the one-touch multiple clamp operation device according to the invention of claim 4 is urged in a direction of pressing the movable wire.
Here, when the external force is applied to the spring that is biased in the direction in which the movable wire is pressed, the movable wire may bend. Therefore, to reduce the load on each clamp mechanism, a biasing force is applied to the spring biased between the base and the plate in a direction in which the movable wire is pushed into the fixed tube.

The spring disposed between the base and the plate of the one-touch multiple clamp operation device according to the invention of claim 5 and the spring for maintaining the clamp mechanism in the clamp release state both clamp the clamp mechanism. The spring is provided with an elastic force in the direction of maintaining the released state.
Here, both springs urge the clamping mechanism in a direction in which the clamp mechanism is kept in the clamp release state, thereby bringing the movable wire into the clamp release state and preventing the bending of the movable wire.

  The one-touch multiple clamp operation device according to claim 1 is provided with an operation clamp for reciprocating an operating rod, attached to the operating rod and a base that allows the operating rod to reciprocate, and between the base A plate provided with a biased spring, a movable non-stretchable fixed tube, a movable wire inserted in the fixed tube and relatively moved between the fixed tube, and the fixed tube or the A clamp mechanism in which either one end of the movable wire is attached to the movable portion and the other end of the fixed tube or the movable wire is attached to the reference fixed portion, and either of the fixed tube or the movable wire is provided. One end is attached to the plate, and the other end of the fixed tube or the movable wire is attached to the base. .

Therefore, the operating rod reciprocates with respect to the base by the operation of the operation clamp that reciprocates the operating rod. The relative movement between the operating rod and the base is a relative movement between the fixed tube and the movable wire, and the relative movement is performed by using either one of the fixed tube or the movable wire as a movable portion and the fixed tube or the movable wire. The clamp mechanism which attached the other end part of the wire to the reference fixing part operates. At this time, the operation of the clamp mechanism disposed at the ends of the fixed tube and the movable wire is determined by the mounting position of the fixed tube and the movable wire. Can be operated.
Therefore, a plurality of clamp mechanisms can be controlled by one operation clamp, and each clamp or clamp release can be individually set, and the type of each clamp mechanism can be arbitrarily selected. .

  In addition to the effect of claim 1, the fixed tube or the movable wire of the one-touch multiple clamp operation device according to claim 2 is provided with an adjusting portion that adjusts the length at least at one end. Each clamp mechanism can finely adjust the operation timing, and the operation timing of each clamp mechanism such as secular change can be adjusted.

  The plate attached to the operating rod of the one-touch multiple-clamp operating device according to claim 3 is provided with an adjusting portion in which a connection position of the plate attached to the operating rod is adjustable. Or in addition to the effect of Claim 2, since the connection position of the said plate attached to the said operating rod becomes adjustable, the timing of operation | movement of all the clamp mechanisms can be changed simultaneously.

  The spring urged between the base and the plate of the one-touch multiple clamp operation device according to claim 4 is urged in a direction of pressing the movable wire. In addition to the effect described in any one of the above, there is a possibility that the movable wire is bent due to friction in the fixed tube caused by being pushed, but the biasing force is applied by the spring between the base and the plate. It is possible to prevent a large pressing force from being applied only to a specific clamping mechanism, and it is possible to prevent the movable wire from bending.

  The spring disposed between the base and the plate of the one-touch multiple clamp operation device according to the invention of claim 5 and the spring for maintaining the clamp mechanism in the clamp release state both clamp the clamp mechanism. In addition to the effect described in any one of claims 1 to 4, since both springs are provided with the clamping mechanism, the spring is applied with an elastic force in the direction of maintaining the released state. Since the movable wire is brought into the clamp release state and the bending of the movable wire can be prevented by urging the wire in the direction to maintain the clamp release state, the operation is always stable.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that, in the embodiments, the same reference numerals and the same reference numerals are the same or corresponding functional parts, and therefore, redundant description thereof is omitted here.

[Embodiment 1]
First, the overall configuration of the first embodiment of the present invention as a one-touch multiple clamp operation device will be described with reference to FIGS.
In the drawing, an operation clamp 10 that stably stops at two positions by an operation that rotates upward and an operation that rotates downward of an operation lever 11 reciprocates a piston 12 as an operating rod. In the present embodiment, since a desired length is required, the piston rod 14 that secures the length of the piston 12 is connected to the piston 12. However, since the length is necessary, the connection is made and the operation is not distinguished. Therefore, in the description of the embodiment and the like of the present invention, the piston rod 14 and the piston 12 are called. Incidentally, in FIG. 3, the piston 12 has two piston rods and two piston rods. However, when the present invention is implemented, it may be one or more than two. Further, if the piston 12 including the piston rod 14 is regarded as an operating rod, it can be used as a material that is difficult to bend in a state where a cylinder, a triangular prism, a quadrangular prism, a hexagonal prism, and an L metal fitting are combined.
The operation clamp 10 is commercially available as a toggle clamp or a lateral push toggle clamp (lateral push toggle clamp NO.FM150, manufactured by Kakuda Kogyo). The piston 12 (including the piston rod 14) contracts in the operation of rotating upward of the operation lever 11, and the piston 12 expands in the operation of rotating downward.

  The operation clamp 10 is attached by bolting with a bolt 13 having a piston 12 inserted through an upright portion 21 at one end of the base 20. The bottom portion 22 of the base 20 is firmly attached by a plurality of bolts 22a attached to the equipment used. The opposite side of the standing portion 21 of the bottom portion 22 is an output standing portion 23. In FIGS. 1 to 3, the standing portion 21, the bottom portion 22, and the output standing portion 23 constitute a base 25. The inside of the base 25 is protected by a cover 26 so that dust and dirt are not attached. That is, the operation clamp 10 is attached to the base 20 to allow the piston 12 inserted through the base 20 to reciprocate.

  A plate 30 is attached to the free end of the piston 12 opposite to the operation clamp 10. The plate 30 is attached to the free end of the piston 12 by a bolt 31, that is, the end of the piston rod 14. By screwing the bolt 31, the plate 30 slides in the length direction of the piston 12. And the output standing portion 23 are changed, but since they are fixed to the base 20 by the bolts 31, they are not detached from the free end of the piston 12. However, a spring 32 is disposed between the upright portion 21 of the base 20 and an elastic force is applied to push and spread between the upright portion 21 and the plate 30.

The output standing portion 23 is provided with a through hole 23a through which the bolt 31 and the piston 12 can be inserted, so that the piston 12 does not collide with the output standing portion 23 and restrain the movement of the plate 30.
That is, as shown in FIG. 2, when the operation lever 11 is rotated upward, the piston 12 contracts against the elastic force of the spring 32, and as shown in FIG. 3, the piston 12 is rotated downward. Then, the piston 12 expands, and the plate 30 moves to the output upright portion 23 side by the elastic force of the spring 32.

A fixed tube 41 that is easily variable but does not expand and contract in the length direction, and a movable wire 42 that is inserted into the fixed tube 41 and moves relative to the fixed tube 41 in the length direction and does not expand and contract in the length direction. Thus, the connecting wire 40 of this embodiment is configured, and the relative movement distance at one end becomes the relative movement distance at the other end. The movable and non-expandable fixed tube 41 of the connecting wire 40 has a male screw end 43 that is screwed integrally with the end thereof, and the center of the male screw end 43 is formed by the movable wire 42. It is inserted. Further, a locking nut 44 is screwed onto the male screw end portion 43 and can be moved in the length direction of the male screw end portion 43.
In the following description, it is common to the connecting wire 40A, the connecting wire 40B, the connecting wire 40C, and the connecting wire 40D, and it is common to the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D. , B, C, and D are not used.

Therefore, when the male screw end portion 43 is screwed to the output standing portion 23 and the loosening prevention nut 44 screwed to the male screw end portion 43 is tightened to the output standing portion 23 side in this state, the male screw is obtained. The screwed state between the end portion 43 and the output upright portion 23 is locked by the locking nut 44. Therefore, the fixed tube 41 of the connecting wire 40 can be securely fixed to the output standing portion 23 by the locking nut 44 fixed to the end portion, and the length thereof is specified.
The male screw end 43 and the locking nut 44 constitute an adjustment unit 45 that finely adjusts the position of the fixed tube 41, but can be omitted when the fixed tube 41 is mounted and the distance is set accurately. .

Moreover, the movable tube 42 that is movable and does not expand and contract, and the movable wire 42 that is inserted into the fixed tube 41 and moves relative to the fixed tube 41 in the length direction are provided by a stopper 51 that compresses a metal lump. Positioned, the stopper 51 defines the length as an end. When the male screw end 52 is screwed to the plate 30 and a locking nut 53 screwed to the male screw end 52 in this state is tightened to the plate 30 side, the male screw end 52 and the plate 30 are fixed. The screwed state with 30 is locked by a locking nut 53. Therefore, the movable wire 42 of the connecting wire 40 can be securely fixed to the plate 30 with the locking nut 53 fixed to the end thereof.
The male screw end 52 and the locking nut 53 constitute an adjusting unit 50 that finely adjusts the position of the stopper 51, but can be omitted when the fixing tube 41 is accurately attached and the distance is set.

  The other end of the connecting wire 40, for example, the other end of the movable and non-expandable fixed tube 41 has a male screw end 62 fixed integrally with the end thereof as shown in FIGS. The movable wire 42 is inserted through the center of the male screw end 62. Further, a locking nut 63 is screwed onto the male screw end 62 and can be moved in the length direction of the male screw end 62.

Accordingly, the male screw end 62 is screwed into the reference fixing portion 72 extended from the bottom member 71 of the clamp mechanism I70, and the locking nut 63 screwed into the male screw end 62 in this state is used as the reference. When tightened to the fixing portion 72 side, the screwed state of the male screw end portion 62 and the reference fixing portion 72 is locked by the locking nut 63. Therefore, the fixing tube 41 of the connecting wire 40 can be securely fixed to the reference fixing portion 72 by the locking nut 44 fixed to the end portion thereof.
The male screw end 62 and the locking nut 63 constitute an adjustment unit 60 that finely adjusts the position of the fixed tube 41, but can be omitted when the fixed tube 41 is attached and set accurately. .

  Further, the movable tube 42 that is movable and does not expand and contract, and the movable wire 42 that is inserted into the fixed tube 41 and moves relative to the fixed tube 41 in the length direction are positioned by the stopper 61, and the stopper 61 is connected to the end. It is fixed and defined as a part. The movable portion 73 that is pivotally supported by the rotation fulcrum 74 is restrained from rotating by a stopper 61. The stopper 61 can be provided with an adjusting portion for finely adjusting the position of the fixed tube 41 together with the male screw end portion and the locking nut, similarly to the adjusting portion 50.

[Operation clamp]
As shown in FIGS. 5 and 6, the operation clamp 10 used in the present embodiment is commercially available as a lateral push toggle clamp (NO. FM150, manufactured by Kakuda Kogyo). The structure 5 is integrated with the bolt 13 and has a hole through which the piston 12 is inserted. A link body 4 is connected to the structural body 5 by a support shaft 1. Further, the auxiliary link body 6 is connected to the end of the link body 4 by the support shaft 2, and the auxiliary link body 6 is connected to the end of the piston 12 by the support shaft 3. The auxiliary link body 6 is integrated with the operation lever 11.
As shown in FIG. 5 (a), when the support shaft 1, the support shaft 2, and the support shaft 3 are in a straight line, the structural body 5, the link body 4, and the auxiliary link body 6 are in the maximum extended position, and the piston 12 The link mechanism composed of the link body 4 and the auxiliary link body 6 that minimizes the elongation of the link member 6 is in a stable stopped state that does not break. At this time, the operation lever 11 is in the upper position.

When the operation lever 11 is tilted, the support shaft 3 becomes an axis, and the support shaft 2 is moved upward. However, since the length of the link body 4 and the auxiliary link body 6 in the direction of the piston 12 is shortened, as shown in FIGS. 5B and 5C, the piston 12 is moved to the base 20 side according to the distance adjustment. Moving.
Further, when the operation lever 11 is tilted, the support shaft 2 serves as a fulcrum, and the support shaft 2 moves to the front side of the support shaft 3. Since the length of the link body 4 and the auxiliary link body 6 in the direction of the piston 12 is shortened, as shown in FIG. 5C and FIG. Moving.

As shown in FIG. 5 (e), when the support shaft 3 is located between the support shaft 1 and the support shaft 2 and they are in a straight line, the structural body 5, the link body 4, and the auxiliary link body. 6 is in the minimum extension position, and the link mechanism including the link body 4 and the auxiliary link body 6 maximizing the extension of the piston 12 is in a stable stop state in which the link mechanism is folded in half. At this time, the operation lever 11 is in the lower position.
Thus, when the operation lever 11 is at the position shown in FIG. 5 (a) standing upward, the extension of the piston 12 is minimized, and the operation lever 11 is at the position shown in FIG. 6 (e) where the operation lever 11 is lowered. Sometimes, the expansion of the piston 12 is maximized. Here, the stable stopped state means a state in which no change occurs on the operation lever 11 side even when an external force is applied from the piston 12 side.

[Clamp mechanism I]
As shown in FIGS. 2 to 4, in the clamp mechanism I70, a bottom member 71 is attached to a base for intended use with bolts 71a. As a result, the reference fixing portion 72 extended and raised from the bottom member 71 becomes the reference position. Further, the movable portion 73 is pivotally supported by a rotation fulcrum 74 and is prevented from being detached by a screw 77 so that the pivotal support is not easily detached. Therefore, the reference fixed portion 72 and the movable portion 73 have the opening end 72a and the opening end 73a at the upper end thereof as shown in FIG. 4B or closed as shown in FIG. .

  At this time, spring fitting holes 72b and 73b are formed at opposing positions of the reference fixing portion 72 and the movable portion 73, and a spring 75 having an elastic force expanding in the length direction is inserted therein. Therefore, when no energy is applied to the connecting wire 40 from the outside (at the release end), the open end 72a and the open end 73a at the upper end of the reference fixed portion 72 and the movable portion 73 are in an open state.

  Here, first, the fixing tube 41 of the connecting wire 40 has its end portion screwed with the male screw end portion 62 and the reference fixing portion 72 and is locked by the locking nut 63. In this state, the operating lever 11 is rotated upward and downward, and the opening end 72a at the upper end of the reference fixing portion 72 and the opening end 73a at the upper end of the movable portion 73 are opened and closed by the change on the clamping mechanism I70 side at that time. The position of the stopper 61 attached to the movable wire 42 is determined.

  Similarly, for the connection wire 40, one end of the connection wire 40A, the connection wire 40B, the connection wire 40C, and the connection wire 40D is connected to the output upright portion 23 and the plate 30, and the other end is connected to a plurality of clamp mechanisms I70, that is, In FIG. 1, the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D are connected to the clamp mechanism I70A, the clamp mechanism I70B, and the clamp mechanism I70C at any timing by the operation lever 11 of one operation clamp 10. The clamp mechanism I70D can be clamped or released at an arbitrary timing.

  The timing for operating the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D is normally determined by the position setting of the stopper 61, and the clamp mechanism I70A and the clamp mechanism are determined according to the operation timing. The positions of stoppers 61 of I70B, clamp mechanism I70C, and clamp mechanism I70D are determined. Therefore, the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D can be opened / closed at the same time, and the clamp or the clamp release can be set by a slight timing shift.

  Of course, the screwed state of the male screw end portion 43 and the output upright portion 23 can be adjusted on the output upright portion 23 side of the base 20, and it can be locked with the locking nut 44. It can also be adjusted by screwing to the male screw end 52 on the plate 30 side. Also in this case, when the locking nut 53 is tightened to the plate 30 side, the screwed state with the male screw end 52 is locked by the locking nut 53, and the movable wire 42 is secured to the end. 53 is securely fixed to the plate 30.

[One-touch multiple clamp operation device]
Next, the operation of the one-touch multiple clamp operation device of the first embodiment will be described in detail.
When stopped on the upper side of the operation lever 11 of the operation clamp 10, the piston 12 contracts into the mechanism of the operation clamp 10, and the piston rod 14 connected to the end of the piston 12 moves to the upright portion 21 side of one end of the base 20. Has moved. In this state, the plate 30 is moved by the head of the bolt 31 toward the upright portion 21 at one end of the base 20. Accordingly, the plate 30 is also moved to the upright portion 21 side at one end of the base 20 against the elastic force of the spring 32.

  At this time, the fixing tube 41 of the connecting wire 40 is fixed at a predetermined distance between the base 20 and the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D. Absent. However, in the movable wire 42 of the connecting wire 40, the fixed tube 41 is pulled against the elasticity of the spring 32 with the output standing portion 23 of the base 20 as a reference. That is, since the movable wire 42 is attached to the plate 30, the movable wire 42 is pulled inside the fixed tube 41 at the same time.

  The pulling of the movable wire 42 is such that the stopper 61 of the clamp mechanism I70 is rotated about the rotation fulcrum 74 of the movable portion 73, so that the upper end 72a of the reference fixed portion 72 and the upper end of the movable portion 73 are rotated. A force is applied in the direction in which the open end 73a is closed. At this time, since the external force applied between the movable wire 42 and the fixed tube 41 is stronger than the elastic force of the spring 75 and the spring 32, the opening end 72a of the reference fixing portion 72 and the opening end 73a of the movable portion 73 are illustrated. 2 is clamped.

  Conversely, when the operation lever 10 is rotated from the upper position of the operation lever 11 to the lower position shown in FIG. 3 and stopped, the piston 12 protrudes from the mechanism of the operation clamp 10 into the base 20, and the end of the piston 12. The piston rod 14 connected to the part moves to the output upright part 23 side of one end of the base 20. In this state, the head of the bolt 31 is inserted through the through hole 23 a of the output upright portion 23, and the plate 30 is moved to the output upright portion 23 side of one end of the base 20. Accordingly, the plate 30 is also moved to the output upright portion 23 side at one end of the base 20, and is brought into contact with the output upright portion 23 and stopped.

  When the operation lever 11 of the operation clamp 10 of FIG. 1 is rotated from the upper position to the lower position shown in FIG. 3, the piston 12 expands from the upright portion 21 side of the base 20 to the output upright portion 23 side. If this change is directly transmitted to the plate 30, the movable wire 42 cannot follow the speed and bends, and the change may not be transmitted to the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D. . In order to prevent such a situation, the plate 30 is movable to the output upright portion 23 side of the base 20 by the elastic force of the spring 32.

  Of course, at this time, the spring 75 in the spring fitting holes 72b and 73b between the reference fixed portion 72 and the movable portion 73 tries to expand by its own elastic force, and the movable wire 42 is not bent so that the movable wire 42 is not bent. Since it is pulled in the length direction, the movement of the stopper 61 rotates around the rotation fulcrum 74 of the movable portion 73 according to the amount of movement of the movable wire 42, and the opening end 72 a at the upper end of the reference fixing portion 72 and the movable portion The upper open end 73a of 73 is opened. At this time, the external force applied between the movable wire 42 and the fixed tube 41 causes the opening end 72 a of the reference fixing portion 72 and the opening end 73 a of the movable portion 73 to be separated by the elastic force of the spring 75 and the elastic force of the spring 32. Then, the clamp is released as shown in FIG.

  As described above, when the operation lever 11 of the operation clamp 10 is rotated to the lower position shown in FIG. 3 and stopped, the opening end 72a of the reference fixing portion 72 and the opening end 73a of the movable portion 73 open, and the workpiece The W clamp is released. Here, the workpiece W is removed or a new workpiece W is positioned by the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D. Then, the operation lever 11 of the operation clamp 10 is gradually rotated to the upper position shown in FIG. 2, and the workpiece W is moved at a predetermined timing by the clamp mechanism I70A, the clamp mechanism I70B, the clamp mechanism I70C, and the clamp mechanism I70D. Clamp. When a predetermined operation such as measurement, grinding, reworking, or the like is completed in a state where the workpiece W is clamped, the predetermined clamp is released by rotating the operation lever 11 of the operation clamp 10 to the lower position shown in FIG. Can do.

That is, the end of the movable wire 42 can be attached to the reference fixing portion 72 of the clamp mechanism I70, and the end of the fixed tube 41 can be attached to the movable portion 73 of the clamp mechanism I70.
In this embodiment, the rotation of the operation clamp 10 and the work W are clamped or released. In this configuration, only one connection of the clamp mechanism I70 may be reversed, or two or more connections may be reversed.

Moreover, the structure which attached the edge part of the movable wire 42 of this Embodiment to the plate 30 of the base 20, and the edge part of the fixed tube 41 to the output standing part 23 of the base 20 can be reversed. That is, the end of the movable wire 42 can be attached to the output standing portion 23 of the base 20, and the end of the fixed tube 41 can be attached to the plate 30 of the base 20.
In this embodiment, the rotation of the operation clamp 10 and the work W are clamped or released. In this configuration, only one connection on the output upright portion 23 side of the base 20 and the plate 30 side of the base 20 may be reversed, or two or more connections may be reversed.

Furthermore, the adjustment parts 45 and 60 are arrange | positioned at the both ends of the fixed tube 41 of this Embodiment, and the adjustment part 50 is arrange | positioned at the edge part of the movable wire 42.

Thereby, the position of the open end 142a of the reference fixing part 142 formed integrally with the saddle-shaped leg 141 is determined, and the standing reference fixing part 142 is set as the reference position. The movable portion 143 is slidably inserted into the reference fixing portion 142 by the slide portion 148, and is fitted so that the slide portion 148 does not fall downward from the movable portion 143. That is, the slide portion 148 of the movable portion 143 is inserted into the opening of the movable portion 143, and the end portion thereof is stopped by the bolt / nut stopper 149, thereby preventing the movable portion 143 from being detached from the opening of the movable portion 143.
Therefore, the reference fixed portion 142 and the movable portion 143 are closed by the slide portion 148 so that the opening end 142a and the opening end 143a at the upper end thereof are closed as shown in FIGS. 19A and 20A, or FIG. And it opens as shown in FIG.20 (b).

Here, the fixed tube 41 of the connecting wire 40 has an end portion screwed between the male screw end portion 62 and the movable portion 143 and is locked by the locking nut 63. In this state, the operation lever 11 is rotated upward and downward, and the opening end 142a at the upper end of the reference fixing portion 142 and the opening end 143a at the upper end of the movable portion 143 are opened and closed by the change on the clamp mechanism VI 140 side at that time. Next, the position of the stopper 61 for attaching the movable wire 42 to the reference fixing portion 142 is determined.
At this time, a spring fitting hole 142b is formed at a position opposite to the reference fixed portion 142 and the movable portion 143, and a spring 145 having an elastic force expanding in the length direction of the connecting wire 40 is inserted therein. Yes. Therefore, when no energy is applied to the connection wire 40 from the outside, the open end 142a and the open end 143a at the upper ends of the reference fixed portion 142 and the movable portion 143 are in an open state. When the movable wire 42 is moved against the elastic force of the spring 145 with respect to the external force that narrows the space between the fixed tube 41 and the movable wire 42 of the connecting wire 40, that is, the fixed tube 41 of the connecting wire 40, the opening The end 142a and the open end 143a are closed as shown in FIGS. 19 (a) and 20 (a).

  As described above, the one-touch multiple clamp operation device of the above embodiment includes the operation clamp 10 that reciprocates the piston 12 including the piston rod 14 as the operating rod by the operation of the operation lever 11 that stably stops at a plurality of locations. Between the base 20 to which the operation clamp 10 is attached and allows the reciprocating movement of the piston 12 including the piston rod 14 as the operating rod and the piston 12 including the piston rod 14 as the operating rod. The plate 30 provided with the spring 32 biased by the movable member, the movable and non-expandable fixed tube 41, and the movable tube that is inserted into the fixed tube 41 and moves relative to the fixed tube 41 in the length direction. The wire 42 and either one of the fixed tube 41 and the movable wire 42 are connected to the clamp mechanism 70, The movable parts 73, 83, 93, 105, 113, 123 of 0, 90, 100, 110, 120, the other end of the fixed tube 41 or the movable wire 42 are clamped to the clamp mechanisms 70, 80, 90, 100, 110, 120. Are attached to the reference fixing portions 72, 82, 92, 102, 112, and 122, and either one end of the fixed tube 41 or the movable wire 42 is attached to the plate 30 and the other end portion of the fixed tube 41 or the movable wire 42 is attached. Each is attached to the base 20.

  Therefore, the piston 12 including the piston rod 14 as the operating rod reciprocates with respect to the base 20 by the operation of the operation clamp 10 that reciprocates the piston 12 including the piston rod 14 as the operating rod. The relative movement between the piston 12 including the piston rod 14 serving as the operating rod and the base is a relative movement between the fixed tube 41 and the movable wire 42, and the relative movement is either the fixed tube 41 or the movable wire 42. Clamps with one end attached to the movable parts 73, 83, 93, 105, 113, 123 and the other end of the fixed tube 41 or the movable wire 42 attached to the reference fixed parts 72, 82, 92, 102, 112, 122, respectively. Mechanisms 70, 80, 90, 100, 110, 120 operate. At this time, the operation of the clamp mechanisms 70, 80, 90, 100, 110, and 120 disposed at the ends of the fixed tube 41 and the movable wire 42 depends on the mounting position of the fixed tube 41 and the movable wire 42. Therefore, the individual clamping mechanisms 70, 80, 90, 100, 110, 120 can be operated at a necessary timing.

  Therefore, the plurality of clamp mechanisms 70, 80, 90, 100, 110, 120 are controlled by a single operation clamp, and each clamp or clamp release can be individually set. The type of 90, 100, 110, 120 is a one-touch multiple clamp operation device that can be arbitrarily selected.

  Since the fixed tube 41 or the movable wire 42 of the one-touch multiple clamp operation device of the above embodiment is provided with adjusting portions 45, 50, 60 for adjusting the length at least at one end, each clamp mechanism 70, 80, 90, 100, 110, 120 enables fine adjustment of the operation timing, and the operation timing of each clamping mechanism 70, 80, 90, 100, 110, 120 such as secular change can be adjusted.

  The plate 30 attached to the piston 12 including the piston rod 14 as the operating rod of the one-touch multiple-clamp operating device of the above embodiment has a connection position of the plate 30 attached to the piston 12 including the piston rod 14 as the operating rod. Since an adjustable adjustment section is provided, the operation timing of all the clamp mechanisms 70, 80, 90, 100, 110, 120 can be changed simultaneously.

  Since the spring 32 biased between the base 20 and the plate 30 of the one-touch multiple clamp operating device of the above embodiment is biased in the direction of pressing the movable wire 42, the movable wire 42 is pressed. Although there is a possibility of bending due to friction in the fixed tube 41, a biasing force is applied by the spring 32 between the base 20 and the plate 30, and a specific clamping mechanism 70, 80, 90, 100, 110, 120 is applied. Therefore, it is possible to prevent a large pressing force from being applied only to the bending of the movable wire 42.

  The one-touch multiple clamp operation device of the above-described embodiment relates to a plurality of clamp mechanisms, and in particular, operates a plurality of clamp mechanisms simultaneously by a one-touch operation. Since it is not restricted by the stroke, it can be used without being restricted by the thickness and structure of the workpiece. Further, the clamp mechanism can be replaced with another mechanism.
