    The invention relates to a measurement technique. The purpose of the invention is to simplify the design of the measuring console and reduce its dimensions. A measuring console consisting of three consecutively single-coordinate moving sections 2, 3 and 4 is attached to the moving parts of the coordinate measuring machine with a connecting flange, and a contact element is mounted on the free end of the console. However, the moving parts are L-shaped, which facilitates access to the controlled object. Each subsequent section is associated with the previous one (O

    For connection with the console, the column carriage is provided with three spherical protrusions 9, 10 and 11 (see Fig. 2), which fit into the spherical depressions of the mounting flange. The connecting flange is attached to the carriage by spring elements (shown here). This connection allows you to avoid console breakdowns in emergency situations. With the connecting flange, the head part 12 is fastened, to which, in turn, are attached the flat springs 13 and 14 of the spring suspension of the first one-coordinate moving part. These springs ensure the mobility of the console along the Z axis. The second KOHUfji spring 1 is fastened to the intermediate part 15 of a rectangular cross section (see Fig. 5). Flat springs 16 and 17 of the spring suspension of the second one-coordinate moving part, which provide mobility along the X-axis, are attached to the intermediate part. The second ends of these springs are fastened with a square 18 connecting the second and third one-coordinate moving parts of the console (see Fig. 4). The ends of the flat springs 19 and 20, which provide mobility along the Y axis, are also attached to this square. The second ends of these springs are fastened to the end piece 21, which holds the socket 22 for connecting the contact element. With the end part is also fastened rigid rod 23, the passage inside
    The third section of the console and the sensor 24 on the free end of the relative translational displacements of the sections along the Y axis. The second rigid rod 25 is placed inside the first and second sections of the console and fastened with a middle part with an intermediate part 15. Sensors 26 and 27 relative to the ends of the rigid rod are mounted telny translational displacements, respectively, along the Y and Z axes. In parallel with the sensors, dampers 28., 29 and 30 are installed in each section of the console, made in the form of fastened with flat springs covering rigid rods d etaly, and the gap between them and the rod is filled with a viscous liquid.
    All parts of the console are surrounded by leathers made of cylindrical tubular elements 31, 32 and 33, the first of which are fastened to the end piece 21. Dp ensure the mobility of the console sections cylindrical tubular elements are interconnected by corrugated tubular elements 34, and To the head part 1 2, the corrugated tubular element 35 is attached. Thanks to such a connection, the console can perceive loads with a twisting moment around any axis.
    The relative displacement sensors of the sections are made in the form of differential capacitive transducers (see FIG. 6 and 7). Each sensor consists of two internal plates 36 and 37 (in FIG. 6), 38 and 39 (in FIG. 7) attached to rigid rods, and two external plates 40 and 41 (in FIG. 6), .42 and 43 (in FIG. 7), mounted on spring hangers. The third sensor is made similarly and consists of plates 44 and 45, 46 and 47

    (Fig, 4). Between the plates of the sensors maintained a gap of 0, 1-Oj2 mm.
    Inside the tubular casing, capacitor sensor power supply units and their preamplifiers 48, 49, and 50 are also placed, which allows to transmit an amplified signal that is less susceptible to interference.
    Auxiliary parts 51 and 52 are used to secure the tubular casing,
    The measuring console works as follows.

    The connecting flange I is installed on the spherical protrusions 9, 10 and 11 of the coordinate measuring machine, and the contact element 5, corresponding to the upcoming measuring operation, is installed in the connecting socket. Then, according to the control program, the contact element is brought to the controlled surfaces, marking the coordinates of the touch points. The signals from sensors 24, 26 and 27 are used to control the coordinate measuring machine. When moving along the X axis, the interaction of the contact element 5 with the test surface causes a displacement of the end part 21, the flat spring 19 and 20, and the square 18. the sensor 26 and the arrival of a signal proportional to the magnitude of the displacement. This signal, together with the signals of the coordinate system of the measuring machine, makes it possible to determine the coordinate of the measuring element, and but, and the point of tangency. The tubular covers 32 and 33 prevent the meter console from twisting. Similarly, when moving along the Y axis, the flat springs 19 and 20 are deformed, and the amount of displacement is determined by the sensor 24; when moving along the Z axis, the springs 13 and 14 are deformed, and the displacement is determined by the sensor 27, the dampers 28, 29 and 30 oscillations of the elements of the console.
    The measurement console also allows you to operate in scan mode, simultaneously emitting magnitudes of displacements along all three axes and controlling the movement of the drives along these coordinates. If the displacements that occur are greater than the gaps in the sensors, then the connecting flange 1 is torn off from one of the spherical protrusions 9, 10 and I, which causes an alarm signal. This ensures the trouble-free operation of the console.
    The small dimensions of the measuring console, the simplicity of its elements and the ability to quickly install different configurations of contact elements provide it with good performance and a wide range of applications.
