Description

Изобретение относится к общему машиностроению и, в частности, может быть применено для стопорения штуцеров термостатируемых форм литья под давлением.The invention relates to general engineering and, in particular, can be used to lock the fittings of thermostatically controlled injection molding.

Известно стопорное устройство,содержа- ® жащее законтриваемую деталь с многогранной головкой, охватывающей ее стопорный элемент, выполненный в виде подкладки шайбы с лапкой, заделанной. . в базовую деталь и отогнутой на головку пружинной частью с многогранным отверстием W·A locking device is known containing a lockable part with a multifaceted head covering its locking element, made in the form of a washer lining with a foot sealed. . into the base part and the spring part bent over the head with the polyhedral hole W ·

Однако пружинные и упругие стопорящие элементы не рассчитаны на большие силовые нагрузки и на работу в режиме вибраций.However, the spring and elastic locking elements are not designed for large power loads and to work in vibration mode.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату является стопорное устройство, содержащее законтриваемую деталь ® с многогранной головкой, охватывающий ее стопорный элемент, выполненный в виде чашеобразной шайбы с многогранным отверстием в центре, отбортованным по периметру, размещенный в глухом цилиндрическом отверстии на базовой детали с взаимодействующей отбортованными поверхностями многогранной головкой и стенками глухого отверстия,, причем на наружной отбортовке чашеобразной шайбы выполнены стопорящие ; зубья J2J.The closest to the proposed technical essence and the achieved result is a locking device containing a lockable part ® with a polyhedral head, covering its locking element, made in the form of a cup-shaped washer with a polyhedral hole in the center, flanged around the perimeter, placed in a blind cylindrical hole on the base part with interacting flanged surfaces with a multifaceted head and walls of a blind hole, and on the outer flanging of the cup-shaped washer s locking; J2J teeth.

Недостатком его является то, что стопорящий элемент не может быть практически установлен без зазора между многогранной головкой и отверстием в стопорящем элементе, что не исключает возможность проворота законтриваемой детали в пределах зазора в ту илй иную сторону, что приводит к разгерметизации соединения.Its disadvantage is that the locking element cannot be practically installed without a gap between the polyhedral head and the hole in the locking element, which does not exclude the possibility of turning the locked part within the gap in either direction, which leads to depressurization of the connection.

Целью изобретения является, повышение надежности стопорения.The aim of the invention is to increase the reliability of locking.

Указанная цель достигается тем, что глухое отверстие на базовой детали выполнено коническим, а стопорный элемент - в виде, радиально размещенных в глухом отверстии, сегментных вкладышей, у которых поверхность, сопряжения со Отенками глухого отверстия, выполнена конической, причем сопряженные;This goal is achieved by the fact that the blind hole on the base part is made conical, and the locking element is in the form of segmented liners radially placed in the blind hole, in which the surface, the interface with the shades of the blind hole, is made conical, and conjugated;

конические поверхности выполнены с углом наклона их образующих, не превышающим угла трения.conical surfaces are made with an angle of inclination of their generators not exceeding the angle of friction.

На фиг. 1 показано стопорное устройство, разрез; на фиг. 2 - вид А на фиг. 1.In FIG. 1 shows a locking device, a section; in FIG. 2 is a view A in FIG. 1.

Стопорное устройство включает базовую деталь 1, законтриваемую деталь 2, ‘ - фиксируемую с помощью клиновид ного стопорного элемента 3.The locking device includes a base part 1, a locked part 2, ‘- fixed with a wedge-shaped locking element 3.

В базовой детали 1, выполнено коническое отверстие 4, соосное охватываемой детали 2, а клиновидный стопорящий элемент 3 выполнен в виде двух сегментных вкладышей с односторонней конической поверхностью каждый и располо женных радиально относительно схватываемой детали 2.In the base part 1, a conical hole 4 is made, coaxial to the male part 2, and the wedge-shaped locking element 3 is made in the form of two segmented inserts with one-sided conical surface each and located radially relative to the workpiece 2.

Конические поверхности отверстия 4 и вкладышей стопорящего элемента 3 выполнены с углом наклона их обра зующих, не превышающим угла трения. Для предохранения вкладышей от выпадания при вибрации предусмотрены винты 5, а для облегчения демонта жа соединения во вкладышах выполнены резьбовые отверстия 6.The conical surfaces of the hole 4 and the inserts of the locking element 3 are made with an angle of inclination of their generators not exceeding the angle of friction. To protect the inserts from falling out during vibration, screws 5 are provided, and to facilitate dismantling the same connections, threaded holes 6 are made in the inserts.

Фиксацию детали 2 от проворота в обе стороны осуществляют с помощью сегментных вкладыщей стопорящего элемента 3, заклинивающихся цод действием усилия и вследствие τοΪό, что конические поверхности отверстия и вкладышей образуют клиновое соединение.The part 2 is fixed from turning on both sides by means of segment inserts of the locking element 3, which are jammed by the force due to the force and due to the fact that the conical surfaces of the hole and inserts form a wedge joint.

Предложенное устройство позволяет надежно застопорить деталь даже при наличии больших крутящих моментов, надежно в работе при любых темпера₅ турах и вибрации, отличается удобством монтажа, допускает многократное его использование.The apparatus can reliably lock the detail even with high torques reliably work in all ₅ rounds tamper and vibration, characterized by ease of installation, it allows for multiple use.
