Self locking device for clamping articles

Abstract

The invention discloses a self-locking clamping device which comprises a temperature control micro-displacement driving device, an area effect stroke amplifier and a bilateral single-action reamed pole reinforcing self-locking clamping device. The temperature control micro-displacement driving device comprises a hollow thin-walled tube which is internally provided with a semi-conductor fast heating / cooling element; the area effect stroke amplifier comprises a driving piston input cylinder body; one end of a driving piston is provided with a heat insulating pad and is fixedly connected with the hollow thin-walled tube, while the other end thereof is provided with liquid medium and is respectively connected with a left output piston structure and a right output piston structure by a pipeline; the articulation point of a bilateral single-action reamed pole is positioned between the left output piston structure and the right output piston structure; an idler wheel is arranged on the left output piston structure and the right output piston structure, one end of the left output piston structure and the right output piston structure is fixedly connected with a force output element. By adopting the temperature control micro-displacement driving device, the self-locking clamping device carries out self-locking clamping by the bilateral single-action reamed pole driven by the area effect stroke amplifier, improves energy source utilization efficiency and has good stability, is no pollution and has excellent self-locking performance.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device adopting a hinge rod booster self-locking mechanism. 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. Chinese utility model patent CN2855645Y discloses a pneumatic clamping device, which is mainly composed of a cylinder, a body, a slider, a connecting rod, a transmission shaft, a pressure rod, and a pressure plate. At the same time, the joint drives the slider to move upwards, and the connecting rod forces the rocker to drive the transmission shaft and the pressure bar to rotate around the fixed point so as to realize ...

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
