Abstract

This invention relates to a measurement technique. The aim of the invention is to reduce the time spent on setting up and expanding the functionality by measuring the outer and inner diameters. The bracket is equipped with a setting mechanism for measuring feet 8 and 9, containing screws 13 and 14, having multidirectional threads and placed on carriages 2 and 3, nuts 15 and 16, placed on legs 8 and 9, screw drive 17, screw 13, coupling 18, and block control 12. By appropriate movement of the measuring feet 8 and 9 from the actuator 17, the measurement force is calibrated, for which the corresponding output signal level on the converter 10 is determined. Adjust the bracket by the standards for different sizes and block the angular displacement This is 13 for each of them, while maintaining the specified level of customization. A size measurement is taken and the output level is recorded by the transducer 10, and the size deviation is determined as the difference between the actual and reference output levels. 1 il. e SL

Description

Calibration is done by measuring-. both internal and in memory

For example, for a chip in case of an arbitrary position of the measuring feet 8 and 9, the screw 11 sets the output signal level to zero on the converter 10, which is indicated on the display of the control unit 12. After that, the measuring legs 8 and 9 are coupled by a drive 17 between themselves to the amount of preload of the springs of parallelograms 4 and 5, corresponding to the specified measuring force when measuring external dimensions 5, which is measured by a dynamometer (not shown),

of the control unit 12, all the angular displacements of the lead screw 13 are brought in. When measuring the size of a part with a supporting bracket, move the measuring feet 8 and 9 with the drive 17 to the extreme fixed position, and then move in the opposite direction until the lead screw 13 does not make the required number of revolutions, which is stored in the memory of the control unit 12 and corresponds to the reference size, at the moment of touching the measuring legs 8 and 9 measured above

both internal and in memory

The control unit 12 pushes all the angular displacements of the lead screw 13. When measuring the part size with the adjusted bracket, move the measuring feet 8 and 9 by the drive 17 to the extreme fixed position, and then move in the opposite direction until the lead screw 13 makes the required number of turns, which is stored in the memory of the control unit 12 and corresponds to the reference size. When the measuring legs 8 and 9 touch the measuring surface, the actuator 17 stops and the output level is fixed on the display of the control unit 12 signal MdO./ € ustb (UBH. Action) with the converter 10, which corresponds to the actual size of the measured part. The magnitude of the deviation D of the actual size from the reference value corresponds to the difference of the output signals.

where K is the transfer coefficient, μm / mV. The presence of a meter feet adjustment mechanism allows a significant reduction in the time required to adjust the bracket to a number of predetermined sizes and makes it possible to measure both external and internal dimensions without changeover.
