The device is used to measure and monitor the bore coordinates in mechanism plates or in the base of the equipment mechanisms and the coaxiality of the bores when these plates are assembled in mechanical workshops in equipment plants in conditions of mass production. It is designed such that its plane table is constructed with reinforcing ribs and capable of rotation. During setting-up, it was possible to displace the lower conical fixator in a direction X-X; the component of the upper conical fixator is mounted in the carriage, being shifted in the direction X-X and Y-Y when working on the ring ball race. Conical fixators are constructed with the cylinder guide and are vertical in sleeves on the ball race without air under the spring pressure in the plate hole and under pneumatic pressure, proceeding to the sleeve stubs - from the plate hole. The cone inclination of the conical fixators is designed as no larger than 1:50 near the cylinder surface. A square ring is pressed in on the sleeve of the upper conical fixator, and the measuring jaw of each indicator is constructed as a strip and touches only one side of this ring. A spring for increasing the measured pressure of the indicator as far as increasing the measured pressure of a micrometer is set up between the measurement jaw and the sleeve. A safety stop is set up on the end of the measurement shaft of each indicator and passes into the groove of the measuring jaw; ... Original abstract incomplete.
