Изобретение относитс к контрольно-измерительной технике.This invention relates to instrumentation technology.

Известно устройство длд измерени рассто ни между ос ми двух отверстий, содержащее корпус, отсчетную головку и рычаг, одно плечо которого имеет сферический наконечник , а второе плечо взаимодействует с отсчетной головкой 1.A device is known for measuring the distance between the axes of two holes, comprising a housing, a readout head and a lever, one arm of which has a spherical tip, and the second shoulder interacts with the readout head 1.

Недостатком известного устройства вл етс невозможность проведени контрол межцентровых рассто ний между ос ми отверстий , лежащих в разных плоскост х.A disadvantage of the known device is the inability to control the center-to-center distances between the axes of the holes lying in different planes.

Цель изобретени - расщирение технологических возможностей.The purpose of the invention is the expansion of technological capabilities.

Поставленна цель достигаетс тем, что устройство снабжено диском, установленным в корпусе с возможностью поворота вокруг своей оси, а рычаг установлен в этом диске эксцентрично относительно его оси.The goal is achieved by the fact that the device is equipped with a disk mounted in the housing with the possibility of rotation around its axis, and the lever is installed in this disk eccentric about its axis.

Кроме того, рычаг установлен с возможностью радиального перемещени .In addition, the lever is mounted with the possibility of radial movement.

На фиг. 1 изображено устройство, общий вид; на фиг. 2 - схема измерени межцентрового рассто ни двух отверстий, расположенных в разных плоскост х, диаметры которых меньще диаметра измерительного наконечника; на фиг. 3 - схема измерени межцентрового рассто ни двух отверстий , диаметр которых больше диаметра измерительного наконечника.FIG. 1 shows the device, a general view; in fig. 2 is a diagram of measuring the center distance of two holes located in different planes, the diameters of which are smaller than the diameter of the measuring tip; in fig. 3 is a diagram of measuring the center distance of two holes, the diameter of which is larger than the diameter of the measuring tip.

Устройство содержит корпус 1, в котором установлен поворотный диск 2, ось диска удалена от оснований корпуса на рассто нии Я. Диск ограничен от осевого перемещени с обеих сторон двум кольцами 3. В корпусе 1 установлен подпружиненный фиксатор 4, контактирующий с одной из двух впадин 5, выполненных через 180° в обращующей диска 2. В диске 2 установлен кронштейн 6, на котором эксцентрично относительно оси диска 2 на рассто нии Б от нее закреплена ось 7 рычага 8, одно плечо которого несет сферический наконечник 9, а другое контактирует с отсчетной головкой 10, закрепленной на кронштейне 6, подпружинен 5 ного относительно рычаге пружиной 11. Дл ограничени перемещени рычага 8 относительно отсчетной гОловки сложит винт 12. Кронштейн 6 с рычагом 8 и отсчетной головкой 10 может перемещатьс в радиальном пазу диска 2 и стопоритс планкой 13 и винтом 14.The device comprises a housing 1, in which the rotary disk 2 is installed, the disk axis is removed from the bases of the housing at a distance I. The disk is bounded from axial movement on both sides by two rings 3. In the housing 1 a spring-loaded clamp 4 is installed that contacts one of the two depressions 5 , performed through 180 ° in the reversing disk 2. In disk 2, a bracket 6 is mounted, on which axis 7 of lever 8 is eccentric relative to the axis of disk 2 at distance B from it, the other arm of which is carried by a spherical tip 9 The head 10 fixed on the bracket 6 is spring-loaded 5 legs relative to the lever by the spring 11. To restrict the movement of the lever 8 relative to the reading head, fold the screw 12. The bracket 6 with the lever 8 and the reading head 10 can move in the radial groove of the disk 2 and stop with the bar 13 and screw 14.

Claims

The controlled part 15 has between the axes of the holes 16 and 17 a distance A. The distance from the plane to the axis of the hole 16 is equal to B. The distance from the plane to the middle of size A is equal to / C. The distance between the forming holes is G. The distance from the plane to the forming hole is E, the distance from the plane to the middle of size F is I. The device works as follows. When the diameter D of the spherical tip 9 is larger than the diameters of the holes, set the part on a plane so that / C is equal to H, where / C is the distance from the measurement plane to the middle of the controlled center-to-center distance; H is the distance from the axis of the disk 2 to the base. Using a measure (plane-parallel tiles) expose the sphere of the tip 9 to the required eccentricity B - and expose the reading head 10 O, A - the controlled center-to-center distance. Moving the body 1 on the plane on which the controlled part 15 is installed, align the sphere of the tip 9 with the axis of the hole 17 and read the deviations from O on the readout head 10. Then turn the disk 2 by 180 ° so that the lock 4 fixes its position, move the stand, combining the sphere of the Tip 9 with the axis of the hole 16 and again read the readout of the reading head 10. The deviation from the nominal value of the controlled center-to-center distance is A1 ± Dg, where D) is the lower deviation; Yes - upper deviation. ; When the diameters of the holes are larger than the sphere of the tip 9, the deviation of the center-to-center distance along the orifices, or the value Γ, is controlled. Set the part on the plane so that I am equal to I, where I is the distance from the measuring plane to the middle of the dimension G,. where A is the nominal controlled center-to-center distance; D1 is the diameter of the upper hole; Yes, the diameter of the lower hole; I is the distance from the axis of the disk to the base. Using a measure (plane-parallel tiles), expose the sphere of the tip 9 to the required eccentricity B and expose O on the click of the reading head 10. By moving the body 1 on the plane on which the part to be installed is installed, align the sphere of the tip 9 with the lower point of the surface of the hole D and read deviations from O on the readout head 10.
