Изобретение относитс к общему машиностроению , в частности к механизмам прерывистого действи , и может использоватьс в полупроводниковой и приборостроительной промышленности, а также в приводах машин с высокой надежностью останова исполнительного органа.The invention relates to general engineering, in particular to mechanisms of intermittent operation, and can be used in the semiconductor and instrument-making industry, as well as in drives of machines with high reliability of shutdown of the actuator.

Известны механизмы враидательного движени с остановками, выполненные в виде зубчатой передачи, одно из колес которой имеет неполный .-зубчатый венец I Одиако такие механизмы пе обеспечивают р.оз.1ож11(н:тн изменени углов поворота ведоMor (j знспа и длит(:;л иости остановок без из .ме1геии размеров вход щих в него звеньев. Known mechanisms for movement with stops are made in the form of a gear, one of the wheels of which has an incomplete.-Gear crown I Odiako; such mechanisms do not provide an R.1.111 (n: tn change in the angles of rotation of the Moro) (j) and lasts (:; There are no station stoppages without the size of the links included in it.

Наиболее близким по технической суш,ности к изобретению вл етс механизм врап ательпого движени с остановками, содержащий соосно расположенные ведущее и ведомое звень , соединенный с ведущим звеном привод, и взаимодействующие между собой два рычага, один из которых воздействует на ведомое звено 2.The closest in terms of technical dryness to the invention is the mechanism of swinging movement with stops, containing coaxially located driving and driven link, connected to the driving link drive, and two levers interacting with each other, one of which acts on the driven link 2.

Этот механизм позвол ет простым способом измен ть угол поворота ведомого звена в пределах 360°, однако не дает возможности обеспечивать различную длительность остановок , как это требуетс , например при использовании подобных механизмов в приводе транспортирующего устройства в проходной камере дл испытани полупроводниковых приборов , а также обладает низкой надежностью из-за фрикционного соединени ведущего и ведомого звеньев, которое допускает проскальзывание .This mechanism allows a simple way to change the angle of rotation of the slave link within 360 °, but it does not allow different durations of stops to be provided, as is required, for example, when using similar mechanisms in the drive of the transport device in the pass-through chamber for testing semiconductor devices, and also has low reliability due to frictional coupling between the drive and driven links, which allows slippage.

Целью изобретени вл етс обеспечение возможности изменени длительности остановок и повышение надежности механизма в работе.The aim of the invention is to provide the possibility of changing the duration of the stops and increasing the reliability of the mechanism in operation.

Дл этого предлагаемый механизм снабжен .храповым колесом, расположенным соосно ведущему и ведомому звень м и размещенным между ними, коническими шестерн ми, оси которых закреплены на храповом колесе перпендикул рно к его оси, и дополнительным приводом, взаимодействующим с рычагом , воздействующим на ведомое звено, ведущее и ведомое звень выполнены в виде конических колес, взаимодействующих с коническими шестерн ми, установленными на храповом колесе, а другой рычаг взаимодействует храповым колесом.For this, the proposed mechanism is equipped with a ram wheel located coaxially with the driving and driven members and placed between them, bevel gears, whose axes are fixed on the ratchet wheel perpendicular to its axis, and an additional drive interacting with the lever acting on the driven member, the driving and driven members are made in the form of conical wheels interacting with bevel gears mounted on the ratchet wheel, and the other lever interacts with the ratchet wheel.

Claims

The rotary motion mechanism with stops includes a drive 1, made in the form of a worm gear, wheel 2 of which is connected to a drive link, which is a conical wheel 3 mounted on the drive shaft 4. On the same shaft 4, a ratchet wheel 5 is freely mounted, carrying four bevel gears 6, the axes 7 of which are fixed on the ratchet wheel 5 and the cross 8, freely mounted on the shaft 4 inside the ratchet wheel 5. Coaxially to the drive shaft 4 is the driven shaft 9, on which the driven link is rotatably mounted o, which is a conical wheel 10 connected to a removable crown I, on the ground surface of which one or several grooves 12 are made. The operation of the mechanism is controlled by an additional drive 13 (for example, electromagnet) and levers 14 and 15 connected between a fork 16. Prulshny 17 and 18 are pressing one lever 14 to the surface of the crown 11, and the other lever 15 - to the ratchet wheel 5. The mechanism is enclosed in the housing 19. The mechanism works as follows. (In the initial position of the mechanism, the lever 15 is lowered and keeps the ratchet wheel 5 in a stationary state, the lever 14 is raised and is on the surface of the crown I. The movement is fed to the wheel 3 through the drive 1. It is in constant engagement with the conical wheels 3 and 10 gears 6 transmit motion to wheel 10 and further-- to a transport device (not shown). At the same time, the lever 14 slides smoothly over the surface of the crown 11 pressed by the spring 17. | At the end of one revolution (or part of the revolution, if a crown with several grooves is used) lever 14 opus kayutsa in the water-bearing az 12 of the ring 11. Simultaneously, the lever 15 is raised from the punch of the ratchet wheel 5, received a pulse from the lever 14 through the fork 16. The movement of the wheel 10 is stopped. determined by a given law of the height of the transport device, the wheel 3, the gears 6 and the ratchet wheel 5 are idling. When the stop time has elapsed, a time relay (not shown) is triggered, the additional drive 13 raises the lever 14, which simultaneously causes the lever 15 to lower, and the mechanism returns to its original position. Claims The mechanism of rotational motion with stops, containing coaxially located driving and driven link, connected to the driving link drive, and two levers interacting with each other, one of which acts on the driven link, characterized in that, in order to ensure that the duration of the stops and increase the reliability of the mechanism in operation, it is equipped with a ratchet wheel located coaxially with the driving and driven members and placed between them, conical brushstones, whose axes are fixed and the ratchet wheel is perpendicular to its axis, and an additional drive interacting with the lever acting on the driven link, the driving and driven link are made in the form of conical wheels interacting with bevel gears mounted on the ratchet wheel, and the other lever interacting with the ratchet wheel .
