Instrument bench vice

Abstract

The invention discloses an instrument bench vice. The bench vice comprises a seat, a movable block, a fixed block, a leading screw, a handle and a positioning pin, wherein the fixed block is fixed on the seat, the positioning pin is arranged on the fixed block to prevent the fixed block from moving, the movable block is mounted on the seat, the rotatablely movable leading screw is fixed on the seat, the handle is fixed on the leading screw, and a V-shaped groove and a spigot groove mutually perpendicular are provided on the movable block. The instrument bench vice provided by the invention enables improvement in strength and service life of small bench vices, and additions in functions of small bench vices.

Description

technical field [0001] The invention relates to a machine tool accessory, in particular to a small or thin instrument vise used for mechanical processing or manual work. Background technique [0002] There are many specifications and varieties in the existing small vise market, because it is a small tool, so the strength of the vise is not very high, and it is easy to damage during use. The defect of the jaw structure causes the vise to be prone to unconventional phenomena such as clamping or not clamping when clamping thin, round and special-shaped workpieces, causing the vise to lose its proper function. Contents of the invention [0003] The object of the present invention is to address the shortcomings of the existing small vise, and to provide an instrument vise, which adds V-shaped grooves and notch grooves perpendicular to each other on the movable block, for clamping round or thin The workpiece is clamped stably and reliably. [0004] The technical solution adopt...
