Clamping device for precision machining of gears of various sizes

Abstract

The invention relates to the technical field of gear machining, and discloses a clamping device for precision machining of gears of various sizes. The clamping device comprises a base, an electromagnet is fixedly connected to the inner wall of the middle of the base, a non-magnetic plate is fixedly connected to the inner wall of the middle of the base, a deformation sleeve is movably connected to the inner wall of the middle of the base, electrorheological fluid is movably connected to the inner wall of the deformation sleeve, and the middle inner wall of the base is fixedly connected with an extrusion column. According to the clamping device for precise machining of the gears of the various sizes, an electromagnet drives a magnetic block to operate, the magnetic block drives a trigger block to move, then a dielectric plate is matched with a positive plate and a negative plate for use, therefore the effect of controlling power-on and power-off of a conductive column is achieved, the electromagnet generates a magnetic field, at the moment, the magnetic block is subjected to inward repulsive force, a piston and the trigger block move, the trigger block drives the dielectric plate to generate relative displacement which is gradually increased, at the moment, the relative area of the positive plate and the negative plate is changed, the area is gradually increased, and the working voltage of a piezoresistor is reached, so that the conductive column is powered on.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a clamping device for precision machining of gears of various sizes. Background technique [0002] Gears are the core transmission components in mechanical motion. The quality of their processing will have a direct impact on the performance and reliability of the mechanical assembly and even the entire device. Most of the gears are produced by cutting and grinding by machine tools. , when it is processed, it is usually fixed on the base of the machine tool with a fixture, and then processed by a machine tool drill. [0003] Most of the existing fixing parts are simple in structure and poor in stability, and are easy to loosen during processing, which will affect the machining accuracy and reduce the quality of the finished gear, and many fixing parts only have the type of horizontal or vertical clamping. function, the multi-directional processing of gears cannot be reali...
