High-precision electric arc type self-adaptive grinding shaping device

Abstract

The invention discloses a high-precision electric arc type self-adaptive grinding shaping device. The device comprises a rack, a horizontal displacement mechanism, a self-adaptive grinding shaping mechanism, a vertical displacement mechanism and a rotary clamping mechanism; the horizontal displacement mechanism is installed at one end of the rack, the self-adaptive grinding shaping mechanism is connected with the output end of the horizontal displacement mechanism through a cantilever, the vertical displacement mechanism is installed at the other end of the rack, and the rotary clamping mechanism is fixed to the output end of the vertical displacement mechanism; and the self-adaptive grinding shaping mechanism comprises an elastic deflection compensation component, a self-orientation electrode component and a self-centering tensioning component, the elastic deflection compensation component is fixed on the cantilever, the self-centering tensioning component is connected with the deflection output end of the elastic deflection compensation component, and the self-orientation electrode component is movably connected to the self-centering tensioning component in a sleeving mode, and can rotate relative to the self-centering tensioning component. According to the device, the high-precision grinding shaping operation on an valve orifice intersection line is achieved, the mechanicaloperation is achieved, the labor intensity is reduced, the efficiency is high, and a valve is not prone to being scratched.

Description

technical field [0001] The invention relates to a high-precision electric arc self-adaptive grinding and shaping device. Background technique [0002] After the valve is machined and drilled, there will be sticky debris at the intersection of the inner orifice of the hole and the inner cavity of the valve, and these debris need to be polished before the valve is sprayed. The existing grinding methods are often processed by manual grinding, which has low precision, high labor intensity, low grinding efficiency, and manual operation is easy to cause scratches on the inner wall of the hole and the inner cavity of the valve; in addition, the inner orifice of the hole The edge is generally an acute angle, which has relatively large resistance to the passage of fluid in the valve, which is not conducive to the circulation of fluid. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a high-precision...
