SPARK-EROSION BORING MACHINE |
摘要 |
FIELD: process engineering. ^ SUBSTANCE: invention relates to spark-erosion boring machine tool intended for making tangential bores in fuel nozzles. Machine tool comprises bed to support slide with tool head and displace crosswise, slide with divider including spindle to carry workpiece. Note here that said divider is mounted on slide to reciprocate therewith while slide is arranged on sector to turn through preset angle in vertical plane. It comprises also bath for working fluid with drive for vertical displacement. Machine tool is furnished with mechanism to recover shape of electrode working part shape. Said electrode is arranged in tool head and provided with ""-shape case attached to vibrator armature with bore for electrode aligned with guide tube bore. Said tube is secured on case cover to accommodate electrode. Said ""-shape case has electrode feed mechanism arranged between vibrator armature and guide tube. Said mechanism is made up of articulated pull roller and pressure roller spring-loaded thereto. ^ EFFECT: higher efficiency and precision. ^ 3 cl, 6 dwg |
