Bench vice long in service life

Abstract

The invention discloses a bench vice long in service life. The bench vice comprises a first fixing base plate and a second fixing base plate, a plurality of bolts are arranged in the first fixing base plate, and a plurality of bolts are arranged in the second fixing base plate. The upper surface of the first fixing base plate is provided with a clamping block, and the clamping block and the first fixing base plate are of an integrated structure. A first longitudinal vertical plate structure is arranged on one side of the top of the clamping block, and the first longitudinal vertical plate structure and the clamping block are of an integrated structure. A second longitudinal vertical plate structure is arranged on the other side of the top of the clamping block, and the second longitudinal vertical plate structure and the clamping block are of an integrated structure. A clamping groove is formed through areas formed by the first longitudinal vertical plate structure and the second longitudinal vertical plate structure on the opposite end faces. According to the bench vice, the thread stress type primary fixing function can be conducted on components, the air pressure effect is conducted on a clamped push plate, and accordingly, the excessive strength caused due to radial force application to the components every time is effectively offset; and at the time, the device is provided with a stress overload preventing mechanism, the damage degree to a thread structure from external force can be reduced, and accordingly the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a bench vise with a long service life. Background technique [0002] At present, in machining places, bench vises are used for a series of tasks such as clamping and cutting of parts, and general bench vises are stressed through threaded structures to achieve clamping. Function, in actual work, due to the radial force applied to the components, the thread structure will have certain limitations due to the thread slip phenomenon caused by the force transition for a long time. Contents of the invention [0003] The object of the present invention is to provide a bench vise with a long service life, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A bench vise with a long service life, comprising a first fixed base plate and a second ...
