    A technique for simultaneously measuring the concentricity of axially spaced cross-sectional locations of a nominally cylindrical test surface is described. A measuring cylinder is pneumatically supported coaxial with the mean axis of the test surface. A plurality of pairs of distance sensors are supported at axially spaced portions of the cylinder. Upon a rotation of the pneumatically supported reference cylinder about its axis, the successive distance readings of the sensors of each pair as such sensors come into registration with a given point on the periphery of the test surface is measured, and each such pair is then radially displaced as a unit by an amount equal to one half the difference between the distances detected by the successive sensors in the pair during the rotation. A subsequent rotation of the supported measuring cylinder about its axis causes the distance readings of the radially displaced sensors to accurately indicate the deviation from concentricity of the associated cross-section location of the test surface.

    The invention relates to technical control in mechanical engineering, namely to measuring the deviations of the shape of cylindrical products.
    Known devices for monitoring cylindricity with the movement of the sensor both around the circumference of the object, and along its generatrix £ 1].
    However, these devices are expensive and difficult to operate.
    Also known are devices containing a housing, elements for centering it on a part using an air cushion, and radius measuring sensors located at different heights [2].
    In these devices, setting the sensor to its initial radius value requires the use of a cylindrical standard for the entire length of the part, otherwise they have low accuracy.
    The aim of the invention is to improve the accuracy of measurement by a certain installation of sensors on the initial value of the radius.
    The goal is achieved in that a device for monitoring deviations from cylindricity, comprising a housing, elements for centering it on the part using an air cushion and sensors ->
    Radius measurement kits located at different heights are equipped with a system of installation sensors, each of which is located diametrically relative to a measurement sensor paired with it, and that the proposed device is set to the initial radius value using a cylindrical caliber, while each pair of sensors is sequentially adjusted according to the sum of their readings on the initial diameter value, match the device with the item being checked, take readings for each measurement sensor, rotate the relative device but items 180 °, remove samples for each sensor and the mounting displace the null setting of each probe on the half of the sampling probe and sensor pair mounting it.
    In FIG. 1 shows an axial section of the device, FIG. 2 - diagram of the installation of the device to size.
    The housing 1 of the device has a pneumatic chamber 2 with its centering nozzles 3 over its entire working surface, creating an air cushion between the device and the surface to be checked. In one of the axial sections of the housing 1 there are new sensors for the initial radius value.
    4 measurement sensors and diametrically opposed installation sensors 5 are installed. In this case, the sensors are nozzles, each of which is connected by a hose to its own amplifying-reading unit. 5 To set each nozzle of the change to the initial nominal size) of the radius of the tested surface using a cylindrical gauge, each pair of 10 sensors is sequentially adjusted according to the sum of their readings on. the initial value of the diameter and match the housing 1 of the device with the tested part. The air cushion provides an unambiguous centering 15 of the housing 1 on the test surface. Take a readout for each measurement sensor, rotate the housing 1 relative to the part 180 ° and take a readout for each installation jo sensor. When taking these readings, the measurement sensor is first, and then the installation sensor is located against the same point of the part being tested. Having determined the half-difference of the counts of 25 pairs of sensors, the measurement sensor setting is shifted to it = 0.5 (2 ^ - Z.

    Sensors 4 are mounted and diametrically opposed installation sensors 5. In this case, the sensors are nozzles, each of which is connected by a hose with its own amplifying reference probe. To install each nozzle and the length of the sensor to the initial nominal diameter of the radius of the test surface, use a cylindrical gauge to successively adjust each pair of sensors according to the sum of their readings to the initial value of the diameter and match the device body 1 with the component being tested. The air cushion both bakes an unambiguous centering of the housing 1 along the test surface. Take a readout for each measurement sensor, rotate the case 1 relative to the part by 180, and take a readout for each installation sensor. When these readings are taken, the measurement sensor is first, and then the installation sensor is located against the same point of the checked part. Having determined the half-difference of the readings of a pair of sensors, the setting of the measurement sensor D 0.5 (Z) is shifted to it. After the implementation of the method for each pair of sensors, all measurement sensors are adjusted to the total initial size. JlpH using a device to monitor deviations from cylindricality match it with the product under test and read the readings for each measurement sensor as deviations from the original nominal radius within a full turn. Thus, the proposed device provides an increase in accuracy due to the simple and accurate installation of sensors at the initial radius value. Claim 1.
