Abstract

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.

Description

technical field [0001] The invention relates to an on-line measuring device and a measuring method thereof for internal grinding force, in particular to a centerless online measuring device and a measuring method for internal grinding force. Background technique [0002] Electromagnetic centerless fixtures are generally used for the grinding and clamping of bearing rings and ring parts. Electromagnetic centerless fixtures rectify alternating current into direct current, generate electromagnetic effects through coils, magnetize the workpiece and suck the end face of the workpiece tightly, so as to realize the axial clamping of the workpiece. position. The radial positioning of the workpiece is to adjust the two supports so that the center of the workpiece placed on the support deviates from the center of the workpiece axis. In the centerless grinding process, the use of electromagnetic centerless fixtures plays an important role in improving the processing accuracy and produ...
