Abstract

The invention discloses an electrode wire tightness adjustment mechanism for an electrical spark linear incising machine tool. The electrode wire tightness adjustment mechanism for the electrical spark linear incising machine tool comprises mechanism fixing seat, a motor, a steel rope, a pulley, a pulley support, a first base, a first sliding block, a distance measuring sensor, a constant force spring, a spring support, a second base, a second sliding block, a tensioning guide wheel and a guide rail. The constant force spring is connected with the tensioning guide wheel through the second base; the free end of the constant force spring is connected with the steel rope through the first base; the distance measuring sensor is arranged on the first base and is used for measuring the distance from the constant force spring to the first base; the first base is arranged on the first sliding block; and the other end of the steel rope bypasses the pulley and is connected with the motor. Through the effective combination of the motor and the constant force spring, the constant force spring is used for microscopically regulating and controlling a tensioning force of an electrode wire, and the motor is used for macroscopically regulating and controlling the tensioning force, the characteristics of tensile force constancy and reaction rapidness of the constant force spring are reasonably utilized, and meanwhile, through the macroscopical regulation and control of the motor, the elongation of the constant force spring is changed within a certain range, so that the problem of system oscillation is well solved.

Description

technical field [0001] The invention relates to the technical field of wire electric discharge machining, in particular to an electrode wire tension adjusting mechanism of a wire electric discharge machine tool. Background technique [0002] The wire electric discharge machining technology uses the moving electrode wire to perform pulse spark discharge on the workpiece, melts and erodes the material, and the cutting fluid washes away the eroded products, so as to maintain a good insulating environment between the electrodes and avoid short circuits. In the fast-feeding wire cutting technology, the high-speed moving wire electrode can better bring the cutting fluid into the cutting groove to achieve better chip removal effect. However, the high-speed movement of the electrode wire is likely to cause the electrode wire to vibrate; in addition, due to the error in the installation of the guide wheel, the friction force of the electrode wire is inconsistent when it moves back an...
