(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ЗАЗОРОВ(54) DEVICE FOR MEASURING GASES

1one

Изобретение относитс к технике линейных измерений, а именно к устройствам дл измерени зазоров между поверхност ми в сложных услови х.The invention relates to a technique for linear measurements, namely, devices for measuring gaps between surfaces in difficult conditions.

Наиболее близким по технической сущности к предлагаемому вл етс устройство Д.ПЯ измерени зазоров, содержащее измерительный наконечник с приводом и указатель зазоров. Измерительный наконечник выполнен в виде конуса (1).The closest in technical essence to the present invention is a device for a PNP gap measurement, containing a measuring tip with a drive and a gap indicator. The measuring tip is made in the form of a cone (1).

Недостатком известного устройства вл етс ограниченный диапазон измер емых величин, возможность измерени только калибровочных отверстий и внутренних кольцевых пазов, невозможность использовани его в сложных услови х работы.A disadvantage of the known device is the limited range of measured values, the ability to measure only calibration holes and internal annular grooves, the impossibility of using it in difficult working conditions.

Цель изобретени - упрощение и сокращение времени измерени в труднодоступных местах в сложных услови х.The purpose of the invention is to simplify and shorten the measurement time in hard-to-reach places under difficult conditions.

Указанна цель достигаетс тем, что в устройстве дл измерени зазоров, содержащем измерительный наконечник с приводом и указатель зазоров, измерительный наконечник выполнен в двух соединенных с возможностью скольжени один относит льно другого неподвижного и подвижного элементов , -на концах которых на ос х установлены шарнирно соединенные друг с другом планки, кроме того, элементы выполнены упругими, в неподвижном элементе выполнены направл ющие дл подвижного элемента , пазы дл скольжени по ним оси од ной планки и наклонный упор, а подвижный элемент св зан гибкой св зью с указателем зазора и подпружинен в направлении их взаимного перемещени .This goal is achieved by the fact that in a device for measuring gaps containing a measuring tip with a drive and an indicator of gaps, the measuring tip is made in two connected with a possibility of sliding, one relating to flax the other fixed and movable elements, the ends of which are pivotally connected to each other on the axes on the other side of the strap, in addition, the elements are made resilient, in the stationary element there are made guides for the movable element, grooves for sliding along it the axis of one strap and inclined pack p, a movable member coupled to a flexible bond pointer gap and is spring-loaded in the direction of their mutual movement.

Устройство содержит два элемента 1 и 2. Элемент 1 жестко соединен с опорной плитой 3. Элемент 2 соединен с указателем зазора 4 гибкой св зью и приводом 6. На концах элементов 1 и 2 на ос х (не показаны ) установлены щарнирно соединенные между собой планки 7 и 8. На конце элемента 1 имеютс пазы 9 дл скольжени The device contains two elements 1 and 2. Element 1 is rigidly connected to the base plate 3. Element 2 is connected to the gap indicator 4 by a flexible coupling and drive 6. At the ends of elements 1 and 2, axes (not shown) are pivotally connected between each other. 7 and 8. At the end of the element 1 there are grooves 9 for sliding

Claims

20 axis of the strap 7 in the plane parallel to the element 1. The element 1 ends with a radius-inclined stop 10 for moving the bar 8. The connection between the elements 1 and 2 along their entire length is carried out by the guides 11. The indicator of the gap 4 has a duplicate arrow 12 of the largest measured gap. The spring 13 serves to return the element 2 to its original position. The gap 14 may be the width of the groove in one piece or the distance between the surfaces of the mating parts 15 and 16. The drive 6 has a lever 17. The device operates in the following way. The support plate 3 installs it onto the surface of the part 15. Elements 1 and 2 are inserted into the measured gap 14. The actuator lever 17 through the flexible link 5 element 2 moves along the plane of the support plate 3. With element 2 the bar 8 also moves, detaching from stop 10, and the axis of the strap 7 moves in the grooves 9 until the strap 7 rests against the surface of the part 16, and the strap 8 - into the surface of the part 15. On the scale of the gap indicator 4 an arrow 12 will fix the value of the gap 14. When you release the lever 17 drive element 2 and the gap indicator mechanism are returned to and original position by a spring 13. Thus, the proposed device allows to simplify and reduce the time measurement gaps, and allows to measure the gaps in remote places. Claims. A device for measuring gaps, comprising a measuring tip with a drive and a gap indicator, characterized in that, in order to simplify and shorten the measurement time, the measuring tip is made of two that are connected with the possibility of sliding one relative to the other fixed and movable elements, at the ends of which x pivotally mounted slats are mounted with each other.

2. The device tio p. 1, characterized in that, in order to ensure the measurement of gaps in hard-to-reach places, the elements are made elastic, the fixed element has guides for the movable element grooves for sliding the axis of one bar and an inclined support on it, and the movable element is connected with a flexible link with the gap indicator and is spring-loaded in the direction of their mutual movement.
