Embodiment Construction

[0012] The structural drawings of a preferred embodiment of the present invention are described in detail as follows: Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the tracking type roundness and diameter online measuring mechanism includes a measuring mechanism base 1 fixedly connected with the grinding wheel frame A tracking rocker 3 driven by a rocker rotation motor 9 and coaxial with the grinding wheel 2 is installed on the measuring mechanism base 1 . Three displacement sensors 4, 5, 6 are installed on the outer end of the tracking rocker arm 3 to contact the outer circle of the workpiece 7 to realize measurement. The above-mentioned measuring mechanism base 1 is a rotary base, which is fixed on the grinding wheel cover 8 by screws, and the rotary base is fixedly connected with the rocking wall rotating motor 9, and the output shaft of the rocking arm rotating motor 9 passes through the center hole of the rotary base. It is fixedly connected with the tracking rocker 3. ...

Abstract

This invention relates to a track round and diameter on-line measurement unit including a base fixedly connected with a grinding wheel frame, a track rocker mounted on the base and rotating the motor drive to wave coaxially with the grinding wheel and three motion transducers mounted on the outer end of the rocker to contact with the outer circle of a work-piece and realizes the measurement.

Description

technical field [0001] The invention relates to a roundness and diameter measuring mechanism, in particular to a tracking type on-line measuring mechanism for roundness and diameter. Background technique [0002] In the existing technology, the grinding process of the eccentric circle (such as grinding the crankshaft journal) often requires stopping the machine to detect the roundness and diameter of the eccentric circle, which affects the production and processing accuracy. With the development of modern numerical control technology and grinding technology, tracking grinding technology has been widely used, especially in eccentric circle tracking grinding, such as crankshaft grinding, which shows its high efficiency. Due to the characteristics of tracking grinding, the shape and size of the final grinding results are more difficult to control than conventional grinding methods. However, as long as the actual shape and size of the grinding process can be known, correspondin...
