AI Technical Summary
Technical Problem
The clamping mechanism driven by existing liquid cylinders cannot achieve the force-enhancing effect, and the liquid cylinder directly bears the load, which affects the service life and clamping reliability.
Method used
The force output from the hydraulic cylinder is amplified by the wedge block, and the sliding cooperation between the main driving wedge block and the clamping wedge block is used to achieve clamping of the object and prevent the liquid cylinder from directly bearing the load.
Benefits of technology
The clamping force is achieved with greater than the output force of the hydraulic cylinder, extending the service life of the hydraulic cylinder, and improving the reliability of clamping.

Abstract
The utility model discloses a double-clamping type tool, which belongs to the technical field of clamps and comprises a base, a left clamping mechanism and a right clamping mechanism, and the left clamping mechanism and the right clamping mechanism are symmetrically arranged on the base. Each of the left clamping mechanism and the right clamping mechanism comprises a hydraulic cylinder, a main driving wedge-shaped block and a clamping wedge-shaped block; the main driving wedge block is fixedly connected with the extending end of a piston rod of the hydraulic cylinder; the clamping wedge block is in sliding fit with the base; an object placing space is formed between the two clamping wedge blocks of the left clamping mechanism and the right clamping mechanism; when hydraulic oil is introduced into the first cavity of the hydraulic cylinder, the two clamping wedge blocks of the left clamping mechanism and the right clamping mechanism clamp an object; and when hydraulic oil is introduced into the second cavity of the hydraulic cylinder, the two clamping wedge blocks of the left clamping mechanism and the right clamping mechanism release the clamping of the object. According to the tool, force output by the hydraulic cylinder can be amplified through the wedge-shaped block, then an object is clamped, the situation that the hydraulic cylinder directly clamps the object can be avoided, and the service life of the hydraulic cylinder is prolonged.
