Description
Обрабатываема деталь 9 закреплена U1 .кронштейне 10, жестко соединенном с копиром 2. В зависимости от формы обрабатываемой поаерхностн (Г - вынукла , Д - вогнута ) деталь размещают слева или справа от оси О вращени инструмента . При этом профиль копира 2 выполь:2н в форме эволюты обрабатываемого профил Д (или Г).The workpiece 9 is fixed with U1. The bracket 10, which is rigidly connected to the camcorder 2. Depending on the shape of the surface to be machined (G is the drape, D is concave), the part is placed to the left or right of the rotation axis O of the tool. At the same time, the profile of copier 2 vopol: 2n in the form of an evolute of the processed profile D (or G).
Если обрабатываемый профиль (эвольвента ) задан napaMieitpHqecKHMH уравнени ми (f); г/п i,(t), то координаты Хк И УК профил копи1ра (эволюты) определ ютс по формулам:If the profile being processed (evolvent) is given by the napaMieitpHqecKHMH equations (f); i / i, (t), then the coordinates Xk and the CC of the copier profile (evolute) are determined by the formulas:

Устройство снабжено механизмам качани копира, содержащим щатун 11, шаркирно соединенный одним концом с копиром , а вторым с кривошипом 12, установленным на выходном валу редуктора (не показан).The device is equipped with swinging mechanisms for a copier, which contains a rod 11, which is ball-connected at one end with a cam and the second with a crank 12 mounted on the output shaft of the gearbox (not shown).
При работе устройства вращаетс к(рир-ошип 12 и через щатун // сообщает копиру 2 качание без скольжени по опорной плите 1. Вместе с копиром перемещаетс обрабатываема деталь 9, при этом в процессе обкатки вращак щимс инструментомWhen the device is working, it rotates to (rip-oship 12 and through the rod // tells the copier 2 to swing without sliding on the support plate 1. The workpiece 9 moves along with the copier, while during the running process the rotating tool

Так как люба касательна iK эволюте (профилю Е копира 2) вл етс нормалью к эвольвенте (профилю Д детали), то при подаче изнощенного 5 инструмента на врезание на величину износа вдоль этой касательной, т. е. опорной плоскости плиты, припуск во всех точках профил детали будет сн т одинаковой величины , т. е. износ инструмента по диаметру не вызовет по влени кинематической погрещности обработки.involute copier. Since any tangent iK evolute (profile E of copier 2) is normal to the involute (profile D of the part), when applying a worn out 5 tool for plunging to the amount of wear along this tangent, i.e. the reference plane of the plate, the allowance at all points the profile of the part will be removed of the same size, i.e. tool wear by diameter will not cause the occurrence of kinematic error of machining.
Возможен вариант исполнени устройства , когда копир с деталью неподвижны, а качани по копиру совершает опорна плита с установленными на ней столом, инструментом и механизмом подачи. В это1М варианте устройство целесообразно использовать дл обработки крупногабаритных деталей.A variant of the device is possible when a copier with a part is stationary, and a base plate with a table, tool and a feeder mounted on it is swinging around the copier. In this version of the device, it is advisable to use the device for processing large parts.
