Description of the Related Art At present, the industrial world attaches great importance to the efficiency of production and the convenience of production work, so that some manufacturers can only sandwich a single work piece according to their machining requirements. The vise has changed the design so that it can sandwich two workpieces at the same time. However, the work pieces that the conventional twin clamp vise can clamp are limited to those having the same size. Therefore, if there is a considerable difference in the clamping dimensions of the two workpieces, the two workpieces cannot be clamped at the same time, and liners of different thickness can be applied to it, and both can be clamped simultaneously. It is necessary to be able to do so, and such a method of correcting the pinch is extremely troublesome and impractical.
Also, the pinching method used for this is a conventional general pinching method, that is, the axial force is generated by mutual frictional pressing between the spiral surface of the screw rod and the spiral slope of the screw hole of the movable jaw, It is a method of pressing the spiral slope of the work piece so that the movable jaw can pinch the work piece.There is no other force-type pinching effect other than the spiral component force, so the phenomenon of pinching force always occurs, and the machining accuracy of the work piece Will affect. Furthermore, the conventional double-clamping table vise does not have the function of automatic centering, so when the user clamps a workpiece with a vise, the center of the workpiece will be automatically moved unless another vise with an automatic centering function is prepared. In addition to increasing the manufacturing cost, it is extremely troublesome to repeatedly replace the vise like this.

The vise body has fixed jaws and movable jaws on both left and right sides. Left, right on the bottom of the movable jaw left,
When the right screw rod is respectively screwed and the handle drives the transmission mechanism, the left and right screw rods move the movable jaws to approach the fixed jaws, and even if the movable jaws hit the workpiece, further force is applied to the handle. , The threaded rod of the transmission mechanism sinks downward,
The booster mechanism is pushed forward to pull the left and right threaded rods, and the movable jaw gains an increased booster to pinch the workpiece. further,
If you remove the fixed jaw at the center of the upper side, both left and right movable jaws move in the corresponding direction in synchronization, so a vise for automatic centering is formed. And has a function of automatic centering. Further, by the compensating action of the left and right movements of the contact ring of the balancer, the two workpieces sandwiched in both movable jaws of the vise can simultaneously obtain the clamping effect of the boosting force. The handle is provided on the upper side of the transmission mechanism and can rotate in the horizontal direction, and the rotary shaft of the handle is provided with a scale indicating the force of pinching.

物と接触するまで直線移動する。Due to the structural characteristics and connection relationship of the above-mentioned members, the operating state of the twin clamp booster vise of this embodiment is as follows. First, two workpieces to be machined are placed between the left and right movable jaws 13 and 14 and the fixed jaw 12, respectively. At that time, as shown in FIGS. 11 and 12, the larger workpiece is placed on the left side. Place on a vise. Then, by turning the handle 8, the sleeve 61 rotates the child threaded rod 62, the lower clutch ring 64 and the upper clutch ring 63, and the upper clutch ring 63.
632 of the outer ring wall and inner screw 51 of the active bevel gear 51
Since 3 and 3 are screwed together, the active bevel gear 51 rotates as the handle 8 rotates. As a result, the left and right bevel gears 52 and 53 that engage with the active bevel gear 51 are respectively moved to the left and right screw rods 2 and 3 by the slide keys 351 and 241.
And the rotations of the left and right screw rods 2 and 3 occur simultaneously, the left and right movable jaws 13 and 14 are driven toward the fixed jaw 12, and the left movable jaw 13 is between the fixed jaw 12 and Move linearly until it contacts the work piece.

る。At this time, as shown in FIG. 13, when the push-pull knob 54 is pulled out, the steel ball 171 in contact with the right bevel gear 53 provided inside the support board 17 has a concave ring groove 532. Jump out of the concave ring groove 532 ',
The right bevel gear 53 and the active bevel gear 51 are disengaged from the meshed state. Further, the handle 8 is rotated, and the right movable jaw 14 is continuously moved toward the fixed jaw 12 by the movement of the right screw rod 3, and when the workpiece between the fixed jaw 12 and the fixed jaw 12 is hit, the rotation of the handle 8 is stopped. . Then, as shown in FIG. 14, the push-pull knob 54 is pushed inward to restore the meshing state between the right bevel gear 53 and the active bevel gear 51. At this time, since the left and right movable jaws 13 and 14 are both in contact with the workpiece, even if the handle 8 is further rotated,
The right bevel gears 52 and 53 do not rotate, and the active bevel gear 51 and the upper clutch ring 63 are restrained and do not rotate. Thus, as shown in FIG. 4, the child threaded rod 62 of the push rod assembly 6 exhibits downward linear movement by the screw 631 on the inner ring wall of the upper clutch ring 63, and pushes the push block 71 of the booster mechanism 7. Press and move it downwards, and each connecting rod 74 receives the force and pushes the left and right sliding blocks 72, 73 according to the momentum, and moves the left and right sliding blocks 7.
2, 73 are pressed against the sliding sleeves 24 of the right-hand threaded rod 3 and the left-handed threaded rod 2 by receiving a force. As a result, the left and right movable jaws 13 and 14 are moved by receiving the pushing force of the right screw rod 3 and the left screw rod 2 and thus are pushed by the spiral force of the left and right screw rods 2 and 3 themselves. The spiral thrust of the rod assembly 6 and the effect of the booster mechanism 7 pushing the left screw rod 2 or pulling the right screw rod 3 cause a sandwiching effect of the increased boost of the left and right movable jaws 13 and 14. In addition to increasing the clamping force, the increased boosting effect can prevent the left and right screw rods 2 and 3 from loosening.

の挟みを施す。After the above-mentioned first adjustment is completed, the push-pull knob 54 is used for sandwiching a workpiece for mass production each time.
It is possible to achieve the purpose of pinching a workpiece or loosening a workpiece by simply turning the handle 8 and moving the left and right movable jaws 13 and 14 forward or backward at the same time without having to operate. Machining of various workpieces can be performed without further adjustment. Also, as shown in FIG.
If there is some error between the left and right workpiece dimensions and the first adjusted workpiece dimension (the error amount does not exceed 5 mm), the error does not affect the sandwiching range to be adjusted, and both workpieces Can also obtain the same size booster pinch, and if one of the left and right movable jaws 13 and 14 hits the workpiece first, the left screw rod 2 or the right screw rod 3 will move to the left movable jaw 13 or the right. The movable jaw 14 is automatically extended as a fulcrum,
The left contact ring 41 or the right contact ring 42 of the balancer 4 is internally contracted into the support seat 44 to compensate for the error amount of the workpiece,
After both the left and right movable jaws 13 and 14 hit the work piece, the push rod assembly 6 pushes the booster mechanism 7 to sandwich the work piece with the increased boosting force.

効果が達成される。Further, as shown in FIGS. 7, 9 and 10, the fixed jaw 12 at the center of the vise main body 1 may be removed during use, whereby a large-sized workpiece can be sandwiched. , The left and right movable jaws 13 and 14 are positioned at the center of the vise from the beginning, that is, the workpiece that is sandwiched by utilizing the characteristics of advancing and retracting is the same, that is, the reference point for machining is kept constant, and machining during mass machining is performed. The position of the object can be fixed accurately. In addition, FIG.
When a cylindrical work is sandwiched as shown in Fig. 2, if the jaw surfaces of the left and right movable jaws 13 and 14 are V-shaped, the center position of the cylindrical work can be easily obtained, and the effect of automatic centering is achieved. To be achieved.
