Abstract
Изобретение относитс к станкостроению и может быть использовано в торцешлифовальных станках дл обработки различных деталей с высокой точностью. Целью изобретени вл етс повышение точности обработки за счет устранени вли ни люфтов. Механизм грубой подачи состоит из реечной передачи 1, фрикционной муфты 2 и зубчатой передачи с маховиком 3. Механизм тонкой подачи состоит из маховика 4, винтовой пары 5, подвижного клина 6 с малым углом подъема на регулируемой подкладке 7, переходника 8 со сферической опорной поверхностью, поджатого пружиной 9 штока 10 и цангового зажима 11, размещенного в кронштейне стола 12. Дл компенсации неточечностей взаимного положени хвостовика штока 10 относительно отверсти цанги цанговый зажим 11 имеет плавающую шайбу. Зазоры в узлах механизма тонкой подачи выбираютс с помощью пружин. При переключении на тонкую подачу перемещением направл ющей 18, установленной на рейке 15, происходит поворот рычага 19 и зажим цанговой штока 10. Перемещение стола передаетс через винтовую пару 5, клин 6 и шток 10. Так как пружинной 9 шток 10 посто нно поджат к клину 6, он передает движение столу в обоих направлени х. 4 ил.The invention relates to a machine tool industry and can be used in face grinding machines for machining various parts with high precision. The aim of the invention is to improve the processing accuracy by eliminating the influence of backlash. The coarse feed mechanism consists of a rack and pinion 1, a friction clutch 2 and a gear with a flywheel 3. The fine feed mechanism consists of a flywheel 4, a screw pair 5, a movable wedge 6 with a small lifting angle on an adjustable lining 7, an adapter 8 with a spherical bearing surface, spring-loaded 9 stem 10 and collet clamp 11 placed in the bracket of the table 12. To compensate for the inaccuracies of the relative position of the stem of the stem 10 relative to the collet hole, the collet clamp 11 has a floating washer. The gaps in the fine feed mechanism are selected using springs. When switching to a thin feed by moving the guide 18 mounted on the rail 15, the lever 19 rotates and the collet rod 10 is clamped. The movement of the table is transmitted through the screw pair 5, the wedge 6 and the rod 10. Since the spring 9 rod 10 is constantly pressed to the wedge 6, it transmits motion to the table in both directions. 4 il.
