Description

Изобретение касаетс  станка дл  шлифовани  криволинейных поверхностей джинных ,и линтерных колосников, снабженного над рабочим столом крестовым супортом дл  шлифовального круга, получающим автоматическим путем воз ратно-поступательнре движение 8 горизонтальном направлении и вертикальные перемещени  под действием укрепленного на рабочем столе копира. В предлагаемом станке, с целью получить дл  каждЬгЪ места обрабатываемой кривой три расположенные на общей вертикальной пр мой точки: центр шли . фовального круга, точку касани  этого круга с кривой и центр кривизны кривой дл  места касани , - рабочий стол, поворотно укрепленный на оси, св зан рычажной передачей с диском, снабженным фигурной кулачной канавкой.The invention relates to a machine for grinding curvilinear surfaces of genie and lining grates equipped with a cross support for a grinding wheel above a work table, which automatically receive a horizontal direction and vertical movements under the action of a copier fixed on the work table. In the proposed machine, in order to obtain for each place of the processed curve three located on a common vertical straight point: the center went. the foveal circle, the point of tangency of this circle with the curve, and the center of curvature of the curve for the point of tangency — the worktable, pivotally fixed on the axis, is connected by a lever gear with a disk equipped with a figured fist groove.

На прилагаемом чертеже изображен вид станка спереди-.The attached drawing shows the front view of the machine.

Подлежащий щлифовке колосник 5 закрепл етс  на поворотном около оси 21 рабочем столе 4, который при помощи рычагов 11 и 12 св зан с ди ском 7, снабженным фигурной канавкой, в которую входит расположенный на конце рычага 12 кулачок 8. Диск 7 наглухо закреплен на оси 27, на которой также насажено винтовое колесо 17, сцепленное с черв ком 18, получающим вращение при помощи цепной передачиThe grate 5 to be polished is fixed on a work table 4 pivoting about an axis 21, which by means of levers 11 and 12 is connected to a disk 7 equipped with a figured groove, which includes a cam 8 located at the end of lever 12. The disk 7 is tightly fixed on the axis 27, on which is also mounted a screw wheel 17 coupled with a screw 18, which is rotated by means of a chain transmission

от вала 10, который в свою очередь приводитс  во вращение от рабочего щкива 23. В верхней части станка расположена каретка 2, котора  может передвигатьс  в горизонтальном направле НИИ при помощи винта 9, получающего вращение, при помощи цилиндрических зубчатых шестерен, от вала 10, дл  чего на каретке имеетс  укрепленна  на задней ее стороне гайка. При движении каретки 2 супорт 3 может перемещатьс  по вертикали вверх и вниз в пазах 20 с расположенными внутри них, дл  уменьшени  трени , опорными роликами. Вал 10 снабжен конической шестерней 28, сцепленной с другой конической шестерней 29, котора  насажена на вал 13, передающий движение через посредство шестерен 30 и 31 шлифовальному камню б, укрепленному на супорте 3. Шестерни 28 и 29 сид т на шпонках, скольз щих по продольным шпоночным канавкам, профрезерованным на валах 10 и 13. Посто нное положение этих шестерен на супорте обеспечиваетс  вилками, имеющимис  на кронштейне 14, закрепленном на каретке 2. Сила нажати  6 на кривую колосника регулируетс  грузом 22, подвешенным на цепи. На краю стола 4 у стенки станины 1 помещаетс  копир 26, по которому может катитьс  цилиндрический ролик 32, укрепленный на супорте. 3.from the shaft 10, which in turn is driven into rotation from the working bar 23. In the upper part of the machine there is a carriage 2, which can be moved in a horizontal direction by the scientific research institute with a screw 9, which receives rotation, using cylindrical gears, from a shaft 10, for There is a nut on the back of the carriage. When the carriage 2 is moving, the caliper 3 can be moved vertically up and down in the slots 20 with internal rollers to reduce friction. The shaft 10 is equipped with a bevel gear 28, coupled with another bevel gear 29, which is mounted on the shaft 13, transmitting movement through the gears 30 and 31 to the grinding stone b, mounted on the support 3. The gears 28 and 29 are seated on pins sliding along the longitudinal key grooves profiled on shafts 10 and 13. The fixed position of these gears on the support is provided by forks on the bracket 14 mounted on the carriage 2. Pressing force 6 on the grate curve is adjusted by a load 22 suspended from the chain. At the edge of the table 4, a copier 26 is placed near the wall of the bed 1, along which a cylindrical roller 32, mounted on a support plate, can roll. 3
