Abstract

The invention discloses a front quick-operating bench vice. The bench vice comprises a fixed vice body, a movable vice body, a screw rod, and a quick-operating structure arranged at the front end of the fixed vice body, wherein the quick-operating structure comprises a nut, a spring, a threaded sleeve, a connecting plate and a side handle assembly; the nut meshed with the screw rod is arranged in a nut groove; the spring is sleeved on a nut handle and locked by the threaded sleeve screwed in a screw hole; the lower end of the nut handle is inserted into a center hole in the threaded sleeve and eccentrically connected with a side handle through the connecting plate; the side handle is rotated, and the nut moves up and down, so that the nut can be meshed with or separated from the screw rod, and slow-operating and quick-operating actions are realized; and quick propulsion also can be realized when the screw rod and the nut are meshed through threads. The bench vice has a simple structure and is high in manufacturability, low in manufacturing cost and convenient to operate and use, various workpieces can be clamped by jaws, the range is wide, clamping force is large, and the workpieces are firmly and reliably clamped.

Description

technical field

[0001] The invention relates to the technical field of fitter tools, in particular to a front-mounted quick-action bench vise. Background technique

[0002] The quick-action bench vise is a fast clamping tool for fitters, which is mainly used for clamping and fixing workpieces during machining by fitters.

[0003] The existing quick-action bench vise is equipped with a quick-action structure in the middle of the fixed pliers body. The basic principle of the quick-action structure is based on the separation of the screw rod and the screw nut. There are roughly two forms:

[0004] (1) The first fast-acting structure is to design the screw nut as an eccentric wheel structure. One side of the center hole of the eccentric nut has threads and the other side has no threads. Take the right-handed thread as an example: when the screw is rotated clockwise, Depending on the friction force or the action of the key, the screw rod drives the eccentric nut to rotate, and t...
