DEVICE FOR MEASURING AND MONITORING THE ALIGNMENT OF THE MIDDLE AND INTERMEDIATE HOLES RELATIVE TO THE EXTREME Russian patent published in 2022 - IPC G01B5/25 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology and can be used in body parts to measure and control the alignment relative to the common axis of holes, such as those provided in the engine cylinder block for the installation of half inserts and the main necks of the crankshaft. The device contains two coaxially arranged shafts (1) and (2) connected by a hollow cylindrical body (3) with fixed axes (4) and (5) a double-arm lever (6) with spherical contact surfaces when the lever arms (6) interact with the flat end of the plunger (7) centered by bushings (8) and (9) in the shaft hole (2) and the rotation surface of the middle of the five controlled holes. Centering nodes (10), (11), (12), (13) of the device are placed two on each of the coaxially arranged shafts (1) and (2). The measuring unit (14) is made in the form of a flange (36), a hollow stepped cylindrical housing (38), two single-row radial bearings (34), a pusher (32) in contact with the tip of the indicator (15) in the hollow axis (33) with the possibility of interaction with the plunger (7) and the indicator (15).

EFFECT: ensuring the measurement and control of the alignment of the middle and intermediate holes relative to the extreme ones in the body parts.
