Referring to the first to fifth figures, the present invention provides a structural improvement of a double force device for a double force vise, comprising: a double force device 60, the foregoing double force device 60 is used to connect the transmission mechanism 90 of the vise Clamping mechanism. The above-mentioned double-force device 60 includes: a thrust rod 10, wherein the two tapered surfaces 11 and 12 of the thrust rod 10 are respectively provided with a roller 14; a limit guiding member 20, and the limiting guiding member 20 is provided with a diameter To the slot 21, the radial slot 21 is limited to the radial movement of the two rollers 14, and the through hole guide 22 is axially disposed with a through hole 22; a taper guide 30, the taper The guiding member 30 is configured to pass through one of the long rod segments 13 of the thrust rod 10, and the tapered guiding member 30 is provided with two radial tapered surfaces 31, 32 which can be assembled into the radial dissection 21, and the two The radial taper surfaces 31 and 32 are taper surfaces which are gradually thicker toward the outer circumference; a connecting member 40, the connecting member 40 is provided with a recess 41 in the axial direction; a spring 51, and the spring 51 is assembled in the recess 41 of the connecting member 40. And passing through the through hole 22 of the foregoing limit guiding member 20, and the spring 51 is placed on a guiding block 52 at the front end of the thrust rod 10. The main reason is that the radial slot 21 of the limiting guide 20 has a slope angle (θ) from the center to the periphery of 1 to 3 degrees, and the roller 14 transmits the force more reliably and smoothly, and the limit is limited. The inclination angle (θ) of the guide member 20 in the radial direction of the groove 21 can avoid the state of being stuck when the double force device 60 is reset, so that the output of the force output is accurate and smooth, and the probability of failure of the multiple force vice can be effectively reduced. .

Thereby, the transmission mechanism of the Bühler vise clamps the workpiece and continues to feed, and the thrust rod 10 is pushed forward. The forward movement of the thrust rod 10 generates the above-mentioned two radial tapers transmitted by the two rollers 14 to the thicker thickness. The surfaces 31 and 32 are further increased in force to change the direction, so that the two rollers 14 push forward the positioning guide 20, the connecting member 40 and the screw 70 to clamp the workpiece forward, and the two rollers are supported by the two rollers.
