Clamping mechanism for chucking appliance system

Abstract

The invention discloses a clamping device used for a clamp system, comprising a micro-displacement driving device, a stroke magnification device and a displacement output device. The clamping device is characterized in that the micro-displacement driving device comprises a base; a sleeve is arranged outside the base and a super magnetostrictive rod is arranged inside the base; one end of the super magnetostrictive rod is fixedly connected with the base and the other end thereof is connected with an output ring; two sides of the super magnetostrictive rod are provided with frameworks; a coil is arranged between the framework and the sleeve; the stroke magnification device comprises a piston cylinder which is internally provided with a piston; one end of the piston is fixedly connected with the output rod and the other end thereof is provided with a hydraulic chamber which is filled with liquid medium; the displacement output device comprises an output cylinder which is internally provided with an output piston rod, one end of which is fixedly connected with the hydraulic chamber of the stroke magnification device. In the invention, the micro-displacement driving device and stroke magnification device are adopted to drive the displacement output device to carry out the clamping, thus improving the utilization efficiency of the energy resource, and having good stability and generating no pollution.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device driven by a giant magnetostrictive material and a stroke amplification device. Background technique [0002] Whether it is traditional machinery manufacturing or modern machinery manufacturing, the role of machine tool fixtures is very important. The core of the machine tool fixture is the clamping device. [0003] At present, most of the motorized clamping devices widely used in production adopt pneumatic or hydraulic transmission, and cooperate with appropriate clamping mechanisms. The main reason why people use a large number of fluid transmission clamps is that one can obtain a much larger clamping force than manual clamps, and the other is to facilitate the automatic control of the positioning and clamping process. Chinese utility model patent CN2855645Y discloses a pneumatic clamping device, which is mainly composed of a cylinder, a body, a slider, a connecting rod, ...

AI Technical Summary

Problems solved by technology

①The mechanical energy required by the clamping force has to go through many energy form conversion links, resulting in large energy loss and low energy utilization

②There is a high-speed rotating mechanical transmission device, and the noise pollution is relatively serious

③Hydraulic transmission fixtures cannot avoid oil leakage in many links, and thus cause serious ground and air pollution

④Many hydraulic transmission fixtures consume energy in order to maintain continuous clamping force during the cutting process, which is a waste of energy
