Novel bench vice

Abstract

The invention discloses a novel bench vice. The novel bench vice comprises a lead screw, a base, a switch, a separable nut, a scribing flat plate, a magnetic gauge stand, a bolt, a slide block and a movable handle. The novel bench vice is characterized in that the lead screw is connected with the separable nut through a thread; the separable nut is embedded into the slide block; the bolt is positioned at the elongation position of the separable nut; the magnetic gauge stand is arranged at a fixed jaw end; the switch is arranged at the top end of the magnetic gauge stand, and is used for controlling the magnetism of the magnetic gauge stand; the scribing flat plate is arranged at the extension positon of the bottom end of a movable jaw. By adopting the novel bench vice, the jaws can be opened and closed rapidly, the waste of labor force and time is reduced, workpieces are clamped more conveniently, the safety is enhance, the stability is high, the workpieces are fixed more firmly, the structure is simple, and the working efficiency is increased.

Description

Technical field [0001] The invention relates to the field of mechanical processing, in particular to a new type of bench vise. Background technique [0002] At present, when the existing domestic bench vise is used, when the jaw size needs to be adjusted, the handle needs to be used to drive the screw to rotate, but the jaw changes only one pitch for each turn of the screw. When it is necessary to open and close frequently, it may be necessary When the opening and closing space is large, it is very time-consuming and labor-intensive to use. The traditional bench vise is fixedly installed on the bench of the fitter to clamp the clamped workpiece, which is convenient for the fitter to file and saw the workpiece by manual or mechanical processing. However, most of its clamping adopts a screw nut structure. In the process of clamping the workpiece, the operator needs to hold the workpiece with one hand and operate the screw with the other hand to clamp the workpiece, which is inconve...

Problems solved by technology

[0002] At present, when the existing domestic bench vise is used, when the size of the jaw needs to be adjusted, the handle needs to be used to drive the screw to rotate, but the jaw only changes by one pitch every time the screw rotates. When the opening and closing space is large, it is very time-consuming and laborious to use. The traditional bench vise is fixedly installed on the fitter's workbench, and is used to clamp the workpiece to be clamped, so that the fitter can file, saw, etc. the workpiece manually or mechanically. However, most of its clamping adopts the screw nut structure. In the process of clamping the workpiece, the operator needs to hold the clamped workpiece with one hand, and operate the screw to clamp the workpiece with the other hand. The operation is inconvenient and unstable.
