Powerful spinning contrarotation automatic tracking device adopting laser detection and tracking method

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 anti-rotation automatic tracking device and a tracking method using laser detection. Background technique [0002] In spinning processing, there are a large number of thin-walled cylindrical parts with no bottom and multiple steps or parts with arbitrary curved busbars, which are suitable for reverse spinning processing, because not only can high radial dimensional accuracy be obtained, but also positioning and clamping are convenient. , which is conducive to mass automated production. However, the distance that the rotary wheel (or tool) moves in the axial direction during reverse rotation is the full length of the blank. As the axial flow of the metal elongates, the profile track of the rotary wheel and the shape of the workpiece do not have a 1:1 geometric relationship. Therefore, it is feasible to design profiling according to the prin...
