The invention discloses a centreless type inner circle
grinding force online measuring device. The technical scheme includes that the centreless type inner circle
grinding force online measuring device comprises a magnetic disc, an end surface support, a front support and a rear support, the front support consists of a support connector successively arranged axially, a sensor base, a one-way
force transducer, a positioning part, a ball and a limiting cap are sequentially connected at the front end of the support connector along the axial direction of the support connector, the structure of the rear support is identical to that of the front support, the ball is tangent to a workpiece required to be ground and processed, the direction of a line between a tangent point and the center of the ball is consistent to a force measuring direction of the one-way
force transducer,
mechanics characteristics during
processing are converted into electric signals by the one-way
force transducer, the electric signals are outputted after being filtered, and amplified electric signals are converted into digital signals to be inputted into a computer via an amplification processor and an A / D (analog / digital) converter). The centreless type inner circle
grinding force online measuring device has the advantages of ingenious, simple and reasonable structure, high sensibility, fine
linearity, high
repeatability and
measurement precision and the like, and can be mounted in a centreless type internal circular grinding
machine conveniently.
