Abstract

The present invention relates to an improved structure of force magnifying vise, which is composed of a vise unit, a transmission unit, a driving unit, a regulation unit and a force magnifying unit, wherein an external periphery edge of a sleeve of the driving unit is disposed with a key block while one side of the sleeve is fixedly disposed with a lock ring. A flexible element and a press block are mounted in the sleeve and screwed by a screw bushing. An actuating head is screwed with the screw bushing, and an operating section of the actuating head is inserted in an insertion hole of the pressing block so as to allow the activating head to drive the pressing block. In addition, the flexible element of the regulation unit is sleeved to the external periphery edge of the sleeve of the driving unit. The external periphery edge of the sleeve is sleeved to the clutch ring. The clutch ring is disposed with a plurality of axial regulation slots, and a radial sliding slot is connected between the axial regulation slots. A driving cylinder is assembled to the actuating head of the driving unit. The regulation ring is fixed to the clutch ring through a screw bolt, so that the regulation ring can be integrally linked with the clutch ring. Accordingly, the entire length of the vise can be effectively reduced to allow a user to use the vise conveniently in a working environment with narrow space without occupying too much operation space.

By the combination of the above, please refer to the first to fourth figures, the invention is a double-forced vise structure improvement, which can be used for the user to carry out the workpiece clamping operation when the user wants When the workpiece is held by the present invention, the workpiece is placed between the fixed crucible 12 and the movable crucible 13 first, and then the lead screw 21 is rotated to perform the gripping operation of the workpiece.

When the user rotates the lead screw 21, it can drive the angular seat 11 away from the adjusting unit 2, and the movable movable jaw 13 is displaced toward the fixed jaw 12 to reach the vise. The effect of clamping the workpiece can ensure the smooth and firm clamping of the workpiece, and it is helpful for the subsequent processing of the workpiece. The overall operation mode is simple and convenient, and it is practical.

It should be noted that the body 10 is provided with the driving unit 3, the adjusting unit 4 and the double force unit 5 on the side of the corner seat 11, and the user continues after the user has clamped the workpiece on the vise of the present invention. The driving unit 3 is driven into the through hole 431 of the driving cylinder 43 by a rotating tool (not shown) and rotated, so that the operating head 37 of the driving unit 3 rotates and the pressing block 35 is pushed to push the thrust pin 55 of the double force unit 5, The inclined surface 551 of the end of the thrust pin 55 can push the round bar 562 of the V-shaped toggle member 56, and pivot the link 561 of the two toggle member 56 and push the first stop 51. The lead screw 21 can be pushed and displaced toward the fixed crucible 12 (as shown in the fourth figure), so that the workpiece can be surely clamped, so that the clamping effect of the double boost can be achieved, and the clamping force is strong. It is suitable for industrial processing and is practical.

In addition, when the user wants to adjust the relative spacing between the clutch ring 42 and the end of the driving cylinder 43, the adjustment ring 44 can be manually adjusted to the rear side (ie, away from the fixed jaw 12), so that The adjusting ring 44 can integrally interlock the clutch ring 42 and passively displace the key block 33 of the driving unit 3 to the position of the sliding slot 422 of the clutch ring 42 , so that the clutch ring 42 and the adjusting ring 44 can be axially rotated and adjusted. When the elastic member 41 between the clutch ring 42 and the driving unit 3 is in a compressed state, the adjusting ring 44 is axially rotated to the position of the adjusting groove 421 to be set by the key block 33, and the elastic restoring force by the elastic member 41 is used. The clutch ring 42 is integrally coupled with the adjusting ring 44 to be elastically pushed forward relative to the front side of the key block 33. Thus, the section setting of the adjusting ring 44 is completed, and the user can perform multi-stage adjustment of the multi-purpose vise. The size of the supercharged power is very convenient and practical.

Furthermore, since the through hole 431 of the driving cylinder 43 is provided as a hexagonal hole, and can be rotated by the user using the rotary tool, the vise can be effectively removed in addition to the clamping effect of the above-mentioned double-pressure boosting. The overall length is shortened, which makes it convenient for the user to use in a small working environment, does not occupy the operation space, and is extremely economical and practical.

In summary, the double-forced vise structure of the present invention effectively improves various disadvantages of the conventional structure, and the main technical means of the present invention are not found in any related publications, and are in conformity with the application requirements of the invention patent, Apply in accordance with the law, and ask the bureau to grant the patent right of the invention.
