Universal type self-centering floating and directional-clamping device

Abstract

The invention relates to a universal type self-centering floating and directional-clamping device which comprises a fixture body and a floating chuck arranged front and back. The fixture body comprises a sliding block support plate, a trapezoid sliding block and a hydraulic cylinder; the floating chuck comprises a fixture transition plate, an upper half-moon-shaped lever and a lower half-moon-shaped lever; the hydraulic cylinder is connected to one side of the sliding block support plate; the trapezoid sliding block is connected to the other side of the sliding block support plate; a sensor fixing plate is arranged on one side of the sliding block support plate; a sensor is arranged on the sensor fixing plate; the upper half-moon-shaped lever and the lower half-moon-shaped lever arranged oppositely are arranged on the fixture transition plate; a V-shaped clamping jaw is arranged on the upper half-moon-shaped lever; a positioning clamping jaw is arranged on the lower half-moon-shaped lever; and a positioning block is arranged at the position, corresponding to the sensor, on the excircle of the fixture transition plate. According to the universal type self-centering floating and directional-clamping device provided by the invention, a clamping force is increased by utilizing a lever principle, a whole clamping mechanism can float, and the clamping jaw can be replaced according todifferent special parts, so that the parts are reshaped conveniently, and the universality is high.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a universal self-centering floating directional clamping device. Background technique [0002] At present, the automatic fixtures on machine tools that require orientation functions are mainly special-purpose ones, and the runout accuracy of the parts after clamping is affected by the precision of the fixtures.
