In each mother glass substrate 11, a polarizing plate 14 is attached to the surface of a region where a predetermined processing is appropriately performed, and a dummy film 15 having the same thickness and shape as that of the polarizing plate on the surface of the region where the predetermined processing is not properly performed. Attach. Thereafter, a scribe line is formed between the regions on the surface of each mother glass substrate.

Worm screw cutting tool for hobbing machine

본 발명은 호빙머신용 웜나사 가공 툴에 관한 것으로, 보다 상세하게는, 웜기어, 특히 웜나사의 비틀림 각도, 즉 리드값에 상관없이 호빙머신을 이용해 다양한 웜나사의 절삭 가공이 가능하며, 호빙머신 공구대의 구조 변경이나 교체 없이 리드값이 큰 특수사양의 웜나사를 정확하게 나선가공할 수 있도록, 상기 공구대에 고정하여 설치되는 장착부재; 및 상기 장착부재에 결합되는 연결부, 상기 연결부의 일면에 직각으로 결합되는 브래킷, 상기 브래킷의 후면에 결합되는 것으로 상기 브래킷을 관통하는 회전축을 구비한 모터, 상기 회전축에 결합되어 회전하며 외측면에 웜나사 가공용 커터를 구비한 회전체로 이루어진 가공부재;를 포함하는 호빙머신용 웜나사 가공 툴에 관한 것이다. The present invention relates to a worm screw processing tool for a hobbing machine, More specifically, it is possible to cut various worm screws using a hobbing machine regardless of the twist angle of the worm gear, especially the worm screw, that is, the lead value, A mounting member fixed to the tool holder so as to allow the worm screw to be accurately spirally machined; And a motor coupled to the mounting member, a bracket coupled to one surface of the connecting portion at a right angle, a motor coupled to a rear surface of the bracket, the motor having a rotation shaft passing through the bracket, And a working member made of a rotating body having a cutter for threading.

Built-up hyperboloid worm gear-cutting tool, replaceable rotary disposable cutting plates to equip thereof and method of their operation

FIELD: machine engineering. SUBSTANCE: built-up hyperboloid gear-cutting tool has a body and a cutting portion made of insertable gear racks inserted in grooves made on this body along the normal to the lifting angle of the main worm screw line on its initial cylinder diameter, and rotary quick-changeable cutting plates fixed on these racks and provided with profile corresponding to the profile of the rack gears. At that, to simplify the tool structure, each cutting plate is secured on the rack by means of a screw inserted from its rear side in an opening and an opening in the cutting plate, and from the front surface it is provided with a screwed nut. At that, the lower part of the plate profile is inserted by placing its lateral sides into the screw grooves corresponding to its profile and configured on the body the between comb gears, or various kinds of pins installed on the rack. The body is made hyperboloid with screw grooves or cylindrical without screw grooves or with screw grooves. EFFECT: increased accuracy of gear wheel treatment by reduced cutting. 22 cl, 29 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 634 565 C2 (51) МПК B23F 21/16 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2014133209, 12.08.2014 (24) Дата начала отсчета срока действия патента: 12.08.2014 (72) Автор(ы): Настасенко Валентин Алексеевич (UA) (73) Патентообладатель(и): Настасенко Валентин Алексеевич (UA) Дата регистрации: (56) Список документов, цитированных в отчете о поиске: RU 2147496 C1, 20.04.2000.
