Description
Предметом изобретени вл етс резцова оправка дл расточки точных отверстий.The subject of the invention is a cutting mandrel for boring precision holes.
Известны конструкции разжимных многорезцовых резцедержавок, выполненных в виде цанги.Known designs of expandable multi-tool reztsederzhavok, made in the form of a collet.
Однако известные резцедержатели обладают тем недостатком, что они не позвол ют осуществить точную регулировку вылета резцов при их установке и износе в процессе работы.However, the known tool holders have the disadvantage that they do not allow precise adjustment of the tool overhang during installation and wear during operation.
Отличительна особенность описываемой резцовой оправки заключаетс в том, что, с целью осуществлени точной регулировки вылета резцов, передн часть оправки, несуща резцы, выполнена в виде разрезной цанги..A distinctive feature of the described chisel mandrel is that, in order to carry out a precise adjustment of the incidence of the incisors, the front part of the mandrel carrying the incisors is designed as a split collet.
На фиг. 1 схематически изображена резцова оправка с частичным разрезом; на фиг. 2-передн часть оправки, несуща резцы.FIG. 1 schematically shows a cutting mandrel with a partial cut; in fig. 2-front part of mandrel carrying cutters.
Резцова оправка / дл расточки точных отверстий с регулировкой вылета резцов имеет переднюю часть, выполненную в виде разрезной пружин щей цанги 2, состо щей из двух частей, кажда из которых несет укрепленный на ней расточной резец 3. Разжимна часть оправки t имеет внутри коническую расточку, в которую входит конический стержень 4, проход щий через центральное отверстие внутри оправки А При перемещении конического стержн 4 рабоча часть оправки разжимаетс , обеспечива тем самым, тонкую регулировку рабочего диаметра расточных резцов 3 при их установке и износе в процессе работы.A cutter mandrel / for the boring of precise holes with an adjustment of the incision of the incisors has a front part made in the form of a split spring collet 2, consisting of two parts, each of which carries a boring cutter 3 fixed on it. The unclamping part of the mandrel t has a conical boring inside, which includes a tapered rod 4, which passes through a central hole inside the mandrel A. When the tapered rod 4 is moved, the working part of the mandrel expands, thereby providing a fine adjustment of the working diameter of the boring cutters 3 during their installation and wear during operation.
Предмет изобретени Subject invention
Резцова оправка дл расточки точных отверстий с регулировкой вылета резцов, отличающа с тем, что, с целью осуществлени точной регулировки вылета резцов при их установке и износе в процессе работы, передн часть онравки, несуща резцы, выполнена в виде разрезной цанги, разжимаемой посредством конического стержн .A cutting mandrel for boring precision holes with adjustment of the overhang of the incisors, characterized in that, in order to make precise adjustment of the overhang of the incisors during their installation and wear during operation, the front part of the trimmer bearing the incisors is made in the form of a split collet unclenched by means of a tapered rod .
