Description

Ввиду отсутстви  сквозных отверстий в борштангах горизонтальнорасточных станков, крепление в них зат жным болтом нормальных хвостовых фрез невозможно. Известные в насто щее врем  оправки дл  креплени  нормальных хвостовых фрез, ввиду большого консольного вылета, не отвечают требовани м жесткости. Отличительна  особенность способа креплени  хвостовых фрез в борштангах, предложенного согласно изобретению, заключаетс  в том, что примен ют два клина. Один из них ввертывают в конусный хвостовик инструмента, введенного в конусное гнездо борштанги. Другой клин ввод т в ее окно до совпадени  его наклонной поверхности с наклонной поверхностью первого клина.Due to the absence of through holes in the boring bars of horizontal boring machines, it is impossible to mount in them the end bolt of normal tail mills. The currently known mandrels for fastening normal tail mills, due to the large cantilevered overhang, do not meet the requirement of stiffness. A distinctive feature of the method of fastening the tail cutters in boring bars proposed by the invention is that two wedges are used. One of them is screwed into the tapered shank of the tool inserted into the tapered socket of the boring bar. Another wedge is inserted into its window until its inclined surface coincides with the inclined surface of the first wedge.

После этого оба клина ст гивают, например, винтом. Эта особенность обеспечивает повышение надежности и безопасности креплени .After that, both wedges are tightened, for example, with a screw. This feature provides increased reliability and safety of fastening.

На чертеже в качестве примера схематически изображено крепление хвостовой фрезы.In the drawing, as an example, schematically shows the attachment of the tail cutter.

Осуществл етс  предложенный способ в следующей последовательности . В конусный хвостовик фрезы 1 ввинчивают болт 2 с головкой , выполненной в виде клина. Затем фрезу вставл ют в конусное гнездо борщтанги 3. В окно А последней помещают вкладыш 4, также выполненный в виде клина, до совпадени  его наклонной поверхности с наклонной поверхностью первого клина. Во вкладыше, имеетс  сквозное отверстие дл  ст жного винта 5. При завертывании пос педнего наклонна  поверхность первого клина, скольз  по наклонной поверхности второго клина, зат гивает хвостовик фрезы в гнездо борщтанги. При этом вкладыш 4, упира сь в переднюю стенку окна А, удерживает фрезу во врем  ее работы от выт гивани  из гнезда борщтанги. Последн  The proposed method is carried out in the following sequence. In the tapered shank cutters 1 screw the bolt 2 with the head, made in the form of a wedge. Then the cutter is inserted into the cone nest of the borschtang 3. In the window A, the insert 4, also made in the form of a wedge, is placed until its inclined surface coincides with the inclined surface of the first wedge. In the liner, there is a through hole for the clamping screw 5. When the lateral is wound, the inclined surface of the first wedge slides along the inclined surface of the second wedge, pulling the cutter shaft into the borshtanga nest. At the same time, the insert 4, abutting against the front wall of window A, keeps the cutter during its operation from being pulled out of the borschtangi nest. Last

при таком креплении может полностью убиратьс  в соответствующую бабку, повыша  тем самым жесткость системы станок-деталь-инструмент и безопасность креплени .With such a fastener, it can completely retract into the corresponding headstock, thereby increasing the rigidity of the machine-part-tool system and the fastening security.

Предмет изобретени Subject invention

Способ креплени  хвостовых фрез и других подобных инструментов, устанавливаемых в конусном гнезде борштанги, например, горизонтально-расточного станка, отличающийс  тем, что, с целью повыщени  надежности и безопасности креплени , примен ют два клина, один из которых ввертывают в конусный хвостовик инструмента, введенного в соответствующее гнездо борщтанги, а другой ввод т в окно борштанги до совпадени  его наклонной поверхности с наклонной поверхностью первого клина и ст гивают оба клина, например, винтом.A method of attaching tail mills and other similar tools installed in a tapered socket of a boring bar, for example, a horizontal boring machine, characterized in that, in order to increase the reliability and safety of mounting, two wedges are used, one of which is screwed into the tapered shank of the tool Borshtangi are inserted into the corresponding nest, and the other is inserted into the boring bar window until its inclined surface coincides with the inclined surface of the first wedge and tightens both wedges, for example, with a screw.
