(54) УСТРОЙСТВО ДЛЯ ФИКСАЦИИ БЫСТРОСЪЕМНЫХ ДЕТАЛЕЙ(54) DEVICE FOR FIXING QUICK REMOVABLE PARTS

Изобретение относитс к машиностроению и может быть использовано дл фиксации быстросъемиых деталей, подвергающихс знакопеременным нагрузкам .The invention relates to mechanical engineering and can be used for fixing quick-detachable parts subjected to alternating loads.

Известно устройство дл соединени деталей, содержащее эксцентрико-т вую втулку, при торце которой выполнен симметрично отверстию сквозной паз, взаимодействующий с боковыми лысками, выполненными на годовке бол-та в направлении, параллельном ее максимальному эксцентриситету, пропущенный через отверстие втулки болт с эксцентричной головкой, диаметр которой меньше диаметра отверсти в соедин емых детал х и гайку, навинченную на болт tlA device for joining parts is known, comprising an eccentric bushing, at the end of which a through groove interacting with lateral ridges made on the annular side of the bolt in a direction parallel to its maximum eccentricity, passed through the bore of the bushing, has an eccentric head; the diameter of which is less than the diameter of the hole in the connected parts and the nut, which is screwed onto the bolt tl

Недостатком известного устройства вл етс TOJ что оно не обеспечивает надежное соединение при воздействии знакопеременных нагрузок из-за возможной расфиксации при ослаблении резьбового соединени .A disadvantage of the known device is the TOJ that it does not provide a reliable connection when subjected to alternating loads due to possible release when loosening the threaded connection.

Известно также устройство дл фиксации быстросъемных деталей, содержащее полный корпус, на одном из торцов которого выполнен паз, ось, эксцентрично расположенную в корпусе и шайбу, закрепленную на одном из концов оси, а также фиксатор с пружиной и головку с выступом, который обеспечивает фиксацию детали, имеющей ответный выступу паз 21.It is also known a device for fixing quick-detachable parts, comprising a full body, on one of the ends of which a groove is made, an axis eccentrically located in the body and a washer fixed at one end of the axis, as well as a retainer with a spring and a head with a protrusion that fixes the part , having a return protrusion groove 21.

Недостатком данного устройства вл етс то, что оно обеспечивает фиксацию только деталей, имеющих паз иа торце, что ограничивает область применени устройства.The disadvantage of this device is that it provides fixation only of parts having a groove and an end face, which limits the scope of application of the device.

that, in the device for fixing the quick-detachable parts, comprising a hollow body, on one of the ends of which a groove, an axis eccentrically located in the body, and a washer fixed on one of the axis ends, as well as a spring fixture, are made protrusions, one of which is L-shaped, and installed with the possibility of contact with the end of the case, while the L-shaped protrusion is placed in the groove of the case, and the spring of the locking pin is fixed at one end to the housing and the other to the washer. FIG. 1 shows the proposed device, a general view (in the working position); in fig. 2 is a view A of FIG. 1 in FIG. 3 is a view B in FIG. 1. The device comprises a housing 1 with a cavity 2 and a groove 3. Inside the housing there is an axis 4 with a head 5 rigidly fixed at one end mounted eccentrically to the axis 4, on the other - a washer 6 made with an L-shaped protrusion 7 and a protrusion 8 The l-shaped protrusion 7 is placed in the groove of the body 3, and the protrusion 8 comes out. As the body size of the device. On axis 4 is mounted spring 9, one end of which is fixed in the cavity 2 of the housing, and the other on the washer 6. Spring 9 ensures the fixation of the head 5 in the working or non-working position of the device. The device works as follows. With the help of the protrusion 8, the head 5 is installed in a position that does not extend beyond the cross section of the cross section of the housing 1. In this position, the device is inserted into the openings of the parts to be connected to the secondary surface. Then, by turning the protrusion 8, the output t of the head 5 is in a position beyond the cross section of the housing 1. The spring 9 presses the tongue.6 by means of the L-shaped protrusion 7, while providing a secure fit. When exposed to vibration and alternating loads, which tend to turn the head 5 towards the uncoupling side, the spring 9, having an initial torque, twists, increasing its resistance, and returns the head 5 to its original position. To disconnect the parts to be connected, it is necessary to turn the washer 6 and the protrusion 8 in the opposite direction until the L-shaped protrusion 7 contacts the other edge of the groove, i.e. return the head 5 to its original position. To facilitate rotation of the control lever, a groove may be provided in the housing. The application of the proposed invention allows to increase the reliability of the connection of parts and to obtain a significant economic effect due to the expansion of operational capabilities. Claims of the Invention A device for fixing quick-detachable parts containing a hollow core, at one of the ends of which has a groove, an axis eccentrically placed in the housing and a washer fixed on one of the ends of the axis, and also a retainer with a spring, of which This is due to the fact that,. / in order to expand the operational capabilities and increase the reliability of fixation when. impact-alternating loads, washer with two protrusions, one of which is L-shaped, and is installed with the possibility of contact with the end of the case, while the L-shaped protrusion is placed in the groove of the case, and the latch spring is fixed at one end in the case, and the other on the puck.
