Powerful spinning anti-spin automatic tracking device and tracking method using laser detection

Abstract

The invention discloses a powerful spinning contrarotation automatic tracking device adopting laser detection and a tracking method. The automatic tracking device comprises a cylindrical core die and a workpiece arranged on the core die in a sleeving manner; the core die comprises a front end and a back end, when the core die rotates, the workpiece is subject to plastic deformation, and the end generating axial flowing is the back end; a laser device is arranged at the back end of the core die and is installed on a laser device base, a retroreflector installation frame is coaxially arranged at the position, close to the back end, of the core die in a sleeving manner and is in a ring shape, the face, towards the back end, of the retroreflector installation frame is provided with an annular groove, and a plurality of retroreflectors are evenly arranged in the groove; and the center of one retroreflector right faces the transmitting end of the laser device. By means of the device capable of automatically detecting the actual spinning length in real time, the problems that during powerful spinning contrarotation, the lengths of a multi-step cylindrical piece and an any-generatrix part are not likely to be controlled, and the accuracy is low are solved, and the powerful spinning contrarotation automatic tracking device and the tracking method have the beneficial effects of being high in accuracy, capable of achieving automatic control and good in application scope.

Description

Technical field [0001] The invention relates to an automatic tracking device and a tracking method, in particular to a powerful spinning reverse rotation automatic tracking device and a tracking method using laser detection. Background technique [0002] In the spinning process, there are a large number of thin-walled cylindrical parts without bottom and multi-step or any curved busbar parts, which are suitable for reverse spinning, because it can not only obtain high radial dimensional accuracy, but also facilitate positioning and clamping , Which is conducive to mass automated production. However, the distance that the rotating wheel (or tool) moves in the axial direction during reverse rotation is the full length of the blank. With the axial flow of the metal, the trajectory of the rotating wheel profile does not have a 1:1 geometric relationship with the shape of the workpiece. Therefore, it is feasible to design the master model according to the principle of equal volume fo...
