Snap Action Vise

Abstract

The invention discloses a quick-action bench vice. The quick-action bench vice comprises a fixed vice body, a movable vice body, a screw rod and a quick-action clamping device, wherein the movable vice body and the screw rod are integrally assembled together; and the quick-action clamping device comprises a nut assembly and a handle assembly. A swinging block and the screw rod are released from thread engagement while the handle is shifted to a quick-action position; the movable vice body can be rapidly moved to finish rapid clamping or loosening action while being pushed and pulled at the moment; and after the quick action is finished, the handle returns to a slow-action position. The swinging block and the screw rod are closely engaged with each other by threads under an effect of a small tension spring while the handle is shifted to the slow-action position; the movable vice body can be driven by a rotating screw rod to move at a low speed at the moment so as to finish slow clamping or loosening action; in addition, the movable vice body can be also pushed to rapidly move to the direction of the fixed vice body. The quick-action bench vice disclosed by the invention has the advantages of simple and reasonable structure, convenience and quickness for operation, time and labor conservation, high jaw distance adjusting speed, high working efficiency, low labor, strong clampingforce, high precision, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of clamping tools for fitters, in particular to a quick-action bench vise which not only has all the functions of a traditional bench vise, but also has the functions of fast clamping and loosening. Background technique [0002] A bench vise is a clamping tool for fitters, which is mainly used for fixing workpieces during machining by fitters. [0003] (1) Existing ordinary bench vises are basically composed of five parts: movable pliers body, fixed pliers body, screw rod, screw nut and chassis. The specific structure is as follows: a fixed pliers body is installed on the chassis, and the fixed pliers The body and the wire mother are assembled into one body, that is, the two parts do not move relative to each other. The movable pliers body is assembled with the screw rod, and a handle is installed on the outer end of the screw rod which is threadedly engaged with the nut; the movable pliers body runs throug...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage is that the rotating screw can only drive the movable pliers to move at a slow speed, so it can only clamp and loosen the workpiece at a slow speed.

Its shortcomings are: when the screw is turned counterclockwise, the screw and the screw must be separated, so that the movable pliers cannot move with the rotation of the screw, and at the same time, one of the most basic functions of the ordinary bench vise is lost-- --slow release
