Description

(54) РАЗЖИМНАЯ ВТУЛКА (54) EXTENSION SLEEVE

Заготовка издели  крепитс  на оправке 3 il устанавливаетс  в разжимной втулке 5 Вследствие радиальной упругой деформации дополнительных базирующих выступов 7 упругой части разжимной втулки 5, оправка 3 центрируетс  с точностью 0,01 мм с небольшим предварительным нат гом, фиксируетс  от проворота. шипом 4 и приж маетс  к торцу шпиндел  1 трем  винтами 2.The workpiece is fastened on the mandrel 3 il is installed in the expansion sleeve 5. Due to the radial elastic deformation of the additional clamping protrusions 7 of the elastic part of the expansion sleeve 5, the mandrel 3 is centered with an accuracy of 0.01 mm with a slight preliminary tension, fixed by rotation. with a spike 4 and is pressed against the end face of the spindle 1 with three screws 2.

Предлагаема  втулка повышает точность центрировани  детали на станке до 0,01 мм она позвол ет закрепить детали по наруж- диаметру на фрезерных станках с контурной системой программного управлени  и достигнуть высокой точности центрировани  обрабатываемой детали, что улучшит качество обработки, снизит трудоемкостьThe proposed sleeve improves the centering accuracy of the part on the machine to 0.01 mm; it allows you to fix the parts along the outer diameter on milling machines with a contour software control system and to achieve high precision centering of the workpiece, which will improve the quality of processing and reduce labor intensity

установки детали и повысит производительность труда.installation details and will increase productivity.
