Изобретение относитс к машиностроению и может быть использовано в металлорежущих станках дл зажима подвижных узлов, например пинолей.The invention relates to mechanical engineering and can be used in machine tools for clamping moving parts, such as quills.

Целью изобретени вл етс расширение технологических возможностей за счет одновременного зажима двух подвижньпс узлов.The aim of the invention is the expansion of technological capabilities due to the simultaneous clamping of two movable nodes.

На фиг, 1 изображено описываемое ю устройство, разрез; на фиг. 2 - разрез А-А на фиг. 1.Fig, 1 shows the described device, section; in fig. 2 shows section A-A in FIG. one.

Устройство дл зажима подвижных узлов состоит из корпуса 1, в которомThe device for clamping moving parts consists of a housing 1, in which

размещены пиноли 2, два сухар и крыш-5 имное перемещение т ги 7 и 12, ка 3. Каждый из сухарей выполнен ви под действием пружины 13 сухариQuill 2, two crackers and a roof are placed; movement 7 and 12, ka 3 moves. Each of the crackers is made under the action of spring 13 crackers

ке 3 вправо и воздействует упорным элементом 11 на левый клин 9, кото- рьй, перемеща сь вдоль оси и самоустанавлива сь в пазу 8 т ги 7 и в кли новых пазах 10 двух полувтулок 4 и 5 передает усилие на левый сухарь. Сухари перемещаютс в корпусе 1 до упо ра в пиноли 2, сжима при этом пружину 13. В конце вращени винта 12 происходит зажим пинолей 2.ke 3 to the right and acts as a stop element 11 on the left wedge 9, which, moving along the axis and self-aligning in the groove 8 tons 7 and in the wedge grooves 10, two half-sleeve 4 and 5 transfers the force to the left cracker. The crackers are moved in the housing 1 up to the stop in the quill 2, while compressing the spring 13. At the end of the rotation of the screw 12, the quill 2 clamping takes place.

При вращении винта 12 против часо вой стрелки происходит обратное взавиде двух полувтулок 4 и 5. В крьш- ке 3 размещены шпонка 6 и удерживаема ею от проворота т га 7, в которой выполнены пазы 8. В пазах 8 разме- 20 щены клинь 9, взаимодействующие с клиновыми пазами 10, вьшолненными на внутренней поверхности полувтулок 3 и 4, а также с упорными элементами 11 и 12 т ги 7. Упорный элемент 12 25 выполнен в виде винта. Между сухар ми на т ге 7 установлена пружина 13. Устройство работает следующим образом .When the screw 12 is turned against the clock hand, the opposite of the two half-sleeves 4 and 5 is reversed. In key 3 there is a key 6 and it holds it from turning 7, in which grooves 8 are made. In slots 8 there is a wedge 9, interacting with the wedge grooves 10, seized on the inner surface of the half-sleeves 3 and 4, as well as with stop elements 11 and 12 tons 7. The stop element 12 25 is made in the form of a screw. A spring 13 is installed between the rusks on the t 7. The device operates as follows.

I При вращении по часовой стрелке 30 I винт 12 перемвща сь влево, воздейст- I вует на правый клин 9,. который, пере- I меща сь вдоль оси, самоустанавливает- I с в пазу 8 т ги 7 и в клиновых пазах : 10 полувтулок 4 и 5. Правый сухарь, 35 I перемеща сь в корпусе 1, упираетс в ; пиноли 2 и движение винта 12 влево прекращаетс . При дальнейшем врашении винта 12 т га 7 перемещаетс в крышразжимают пиноли 2,I When turning clockwise 30 I, screw 12, moving to the left, affects the right wedge 9 ,. which, moving along the axis, self-aligns I in the slot of 8 tons of 7 and in the V-grooves: 10 half-sleeves 4 and 5. Right rusk, 35 I moving in the housing 1, abuts against; the quill 2 and the movement of the screw 12 to the left is stopped. Upon further screw inching, 12 tons ha 7 is moved to the roof to expand the quill 2,

Claims

Invention Formula

A device for clamping a movable unit, comprising a housing point mounted in ra, with the possibility of moving with two thrust elements and two crackers, designed for dp contact with a movable unit, characterized in that, in order to expand technological capabilities by simultaneously clamping two movable units, The device is equipped with two wedges located between the thrust elements of the rod with the ability to move in the grooves made in the last, each cracker made in the form of two half-sleeves with a Kli n ovymi grooves inner surface and is arranged to po- slednemi contacting one of the wedges.

Ke 3 to the right and acts as a stop element 11 on the left wedge 9, which, moving along the axis and self-aligning in the groove 8 tons 7 and in the wedge grooves 10 of the two half-sleeve 4 and 5, transmits the force to the left cracker. The crackers are moved in housing 1 all the way into the quinces 2, thereby compressing the spring 13. At the end of the rotation of the screw 12, the quenches 2 are clamped.

When the screw 12 is rotated counterclockwise, the opposite occurs;
