Abstract

The invention discloses an automatic double-Z-axis electric spark deposition device and method. A first alternating-current servo motor, a second alternating-current servo motor and a fourth alternating-current servo motor in the X-axis direction, the Y-axis direction and the Z1-axis direction are controlled to move so as to drive an electrode to move to a machining starting point of a workpiece surface; when a third alternating-current servo motor runs, a Z2-axis ram descends so as to ensure that the squeezing force of a rotary deposition gun on the workpiece is equal to a preset value; the first, second and fourth alternating-current servo motors run, and a movement orbit of the workpiece surface is formed by rotating the rotary deposition gun; the height of the electrode is adjusted according to a real squeezing force value measured by a force transducer, wherein when the squeezing force is greater than the upper difference of the preset value, the third alternating-current servo motor is reversed to drive the Z2-axis ram to ascend so as to drive the rotary deposition gun and the electrode to ascend, and when the squeezing force is smaller than the lower difference of the preset value, the third alternating-current servo motor rotates forward to drive the Z2-axis ram to descend; and the elevation movement in the Z2-axis direction is only related to the squeezing force, a deposition layer is more continuous, and the thickness of the deposition layer is more uniform.

Description

technical field [0001] The invention relates to metal surface deposition and electric spark surface deposition technology, in particular to an automatic electric spark deposition device. Background technique [0002] EDM surface deposition uses the energy storage power supply to release energy at the moment of contact between the electrode and the workpiece, melts or even vaporizes the electrode material, and coats it on the surface of the workpiece, thereby forming a layer of high wear resistance, high hardness and corrosion resistance on the surface of the workpiece. Metallurgically strengthened layer. The process has the characteristics of simple operation, high energy utilization rate, wide selection of electrode materials, small thermal response area of ​​substrate and low residual stress, etc. It is widely used in energy, aviation, aerospace, electric power, mining and repair of some precision parts. . [0003] At present, the surface deposition of EDM is mostly perf...
