Controllable bench screw

Abstract

The invention discloses a controllable bench screw which comprises a main body shell. The controllable bench screw can achieve bidirectional clamping by means of a driving source, and meanwhile, the working state of a clamping part can be selected voluntarily in bidirectional clamping according to actual condition, so that the clamping diversity and adaptability are achieved. When voluntary selection is made to the controllable bench screw, a valve switch in a corresponding part can be opened automatically according to the weight of a part in a preventing part, so that the simplicity and practicality are improved. Moreover, the controllable bench screw provided with a movement control mechanism of a liquid telescopic part of a valve rod can communicate spaces of key parts under influence of a high pressure liquid, so that the liquid in corresponding part flows to clamp by corresponding part. In addition, the controllable bench screw provided with a liquid telescopic liquid driving mechanism of the clamping part can drive the liquid under the action of the gravity of the clamping part, so that the working state of the related part is adjusted.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a controllable bench vise. Background technique [0002] At present, bench vises are indispensable in the processing and maintenance of mechanical parts. Most of the existing bench vises are one-way bench vises, which have poor functionality and are relatively single in actual work. Contents of the invention [0003] The object of the present invention is to provide a controllable bench vise to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a controllable bench vise, including a main body shell, the center of the upper end of the main body shell is provided with a main telescopic space, and the top center of the main body shell is installed with a main thread structure. A main threaded rod, a rotating plate is installed on the t...
