Description
(54) АЛМАЗНЫЙ ИНСТРУМЕНТ ДЛЯ СВЕРЛЕНИЯ ОТВЕРСТИЙ(54) DIAMOND TOOLS FOR DRILLING HOLES
1one
Изобретение относитс к области механической обработки твердых и хрупких материалов .This invention relates to the machining of hard and brittle materials.
По основному авт. св. № 578193 известен алмазный инструмент дл сверлени отверстий , содержащий корпус в виде криволинейной трубки с размещенным в нем набором втулок, ведуща втулка которого кине матически св зана с приводом, а ведома с алмазной рабочей коронкой, закрепленной в корпусе с возможностью вращени .According to the main author. St. No. 578193 is a diamond tool for drilling holes, comprising a body in the form of a curved tube with a set of sleeves accommodated therein, the driving sleeve of which is kinematically associated with a drive, and aware of a diamond working crown fixed in the housing for rotation.
Однако известна конструкци инструмента ненадежна в эксплуатации.However, the known construction of the tool is unreliable in operation.
Целью изобретени вл етс повыщение надежности работы инструмента.The aim of the invention is to increase the reliability of the tool.
Поставленна цель достигаетс тем, что промежуточные втулки выполнены со сквозными осесимметричными отверсти ми, в которых размещены с возможностью продольного перемещени стержни, а их концы, размещенные в ведомой втулке, закреплены неподвижно .The goal is achieved by the fact that the intermediate sleeves are made with through-axisymmetric holes in which the rods are placed with the possibility of longitudinal movement, and their ends placed in the driven sleeve are fixedly mounted.
На фиг. 1 изображен предлагаемый алмазный инструмент; на фиг. 2 - узел I на фиг. 1Г на фиг. 3 - узел II на фиг. 1.FIG. 1 shows the proposed diamond tool; in fig. 2 — node I in FIG. 1G in FIG. 3 - node II in FIG. one.
Инструмент содержит корпус 1 с размещенным в нем набором втулок 2 с отверсти ми . Ведуща втулка 3 св зана с приводом 4, а ведома втулка 5 - с алмазоносной коронкой 6, закрепленной в корпусе 1 с помощью щариков 7, установленных в кольцевых пазах через отверсти , закрываемые заглушками 8. Ведуща , ведома и промежуточные втулки соединены через отверсти стержн ми 9, одни концы которых жестко закреплены в ведомой втулке, а другие свободно перемещаютс в отверсти х ведущей втулки 3 и привода 4. Дл подвода сож на корпусеThe tool comprises a housing 1 with a set of sleeves 2 with openings accommodated therein. The drive sleeve 3 is connected to the drive 4, and the driven sleeve 5 is connected to a diamond-bearing crown 6 fixed in the housing 1 by means of balls 7 installed in annular grooves through the holes closed by plugs 8. The drive, driven and intermediate sleeves are connected through holes with rods 9, one ends of which are rigidly fixed in the driven bushing, while others freely move in the openings of the driving bushing 3 and the actuator 4. For supplying coolant to the housing
закреплен щтуцер 10.fixed clamp 10.
Инструмент работает следующим образом .The tool works as follows.
Привод 4 вращает ведущую втулку 3, при этом .ведома втулка 5 передает крут щий момент рабочей коронке 6 при помощи стержней 9 и промежуточных втулок 2. Трубчатый корпус 1 перемещают по траектории , радиус которой равен радиусу кривизны корпуса. Сож к рабочей коронке 6 подают через штуцер 10 и отверсти набора втулок 2, при этом сож удал ет ц.лаг.; и обеспечитвает смазку трущихс поверхностей втулок. После завершени сверлени корпус возвращают в исходное положение по той же траектории. Инструмент обеспечиваетThe actuator 4 rotates the driving sleeve 3, wherein the known sleeve 5 transmits the torque to the working crown 6 using rods 9 and intermediate sleeves 2. The tubular body 1 is moved along a path whose radius is equal to the radius of curvature of the body. Sozh to the working crown 6 is fed through the nozzle 10 and the openings of the set of sleeves 2, while the soot removes the col.lag .; and provides lubrication of the bushing surfaces. After completion of drilling, the housing is returned to its original position along the same path. Tool provides
сверление тЪровых отверстий в хрупких и твердых материалах.drilling holes in brittle and hard materials.
