DYNAMOMETRIC DEVICE FOR SYSTEM FOR COMPONENT PRESSING ON PART Russian patent published in 2020 - IPC G01L5/24 G01L1/02 B25B29/02 

FIELD: machine building.

SUBSTANCE: present invention relates to the field of crimping devices for the nuts and studs on the part, particularly, crimping devices performing the force attachment. Device (10) for measuring force, applied by means of fastening device (20) of crimped element, wherein said device is provided with threaded rod (21) having internal or external thread, wherein device comprises: hydraulic chamber (11), containing fluid (11') and extending along longitudinal axis (Ox); piston (12) made with possibility of sliding inside hydraulic chamber (11) along axis (Ox); threaded connector (13), attached to piston (12), wherein threaded connector (13) has external or internal thread made such that threaded rod (21) is screwed on threaded connector (13), as a result of which threaded rod (21) can apply axial force (Fa) to piston (12), forming movement of piston (12) along axis (Ox), inside hydraulic chamber (11); pressure gauge (14), communicating with hydraulic chamber (11) and configured to measure pressure (P) inside hydraulic chamber (11) created by axial force (Fa), applied to piston (12) by means of threaded rod (21) of fastening device (20), stop (17), configured to receive opposite support (22) of fastener (20) for securing fastener (20) to device (10) by screwing threaded rod (21) on threaded connector (13) and resting opposite stop (22) in stop (17).

EFFECT: technical result is creation of a dynamometric device suitable for crimping devices using force, which is compact, mobile and is made with possibility of reliable and effective measurement of maximum force.
