Description

A kind of length measuring device of magnetic suspension bearing
Technical field
The utility model relates to accurate sizing technologies, and in particular to all kinds of metal pipe material production lines such as stainless steel tube, titanium tube Accurate sizing measuring technique.
Background technique
Currently, needing to be cut according to the scale requirement of client in the manufacturing of all kinds of metal pipe materials such as stainless steel tube, titanium tube Pipe cutting material, and in the production line of all kinds of metal pipe materials such as stainless steel tube, titanium tube, length measuring device is substantially using rolling bearing Device, rolling bearing are directly contacted with shaft, and with the increase of rolling bearing frequency of use, rolling bearing can rub with shaft Scrape along vibration, can wear, these can all cause tubing in Length-fixing cutting, and the size of tubing deviates, shadow when serious Ring the quality of product.Therefore, scale measuring device plays a crucial role the Length-fixing cutting and production efficiency of metal tube.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies of existing scale technology, provide the novel magnetic suspension bearing of one kind Length measuring device, the scale suitable for all kinds of metal pipe material production lines such as stainless steel tube, titanium tube measure, it is ensured that all kinds of metal tube lengths The accuracy of cutting keeps the fluency of production line, improves the production efficiency of all kinds of metal tubes.
To achieve the above object, technical solution provided by the utility model is a kind of length measuring device of magnetic suspension bearing, it It include scale idler wheel, left radial magnetic suspension bearing, axial magnetic suspension bearing, rotating shaft thrust disc, electromagnetic damper, right side diameter To magnetic suspension bearing, shaft, driving motor.Wherein, left radial magnetic suspension bearing and right radial magnetic bearing structure phase It together, is all to be made of radial magnetic bearing stator and pole coil, radial magnetic bearing stator has 8 pole shoes, pole line Circle is respectively wound around above 8 pole shoes;Axial magnetic suspension bearing is made of thrust bearing stator and permanent magnetic iron block, and thrust bearing is fixed Son is provided with 6 magnetic holders, and permanent magnetic iron block is fixed in magnetic holder.
The left radial magnetic suspension bearing and right radial magnetic suspension bearing keeps shaft radial by becoming control case control The dynamic balance in direction;Axial magnetic suspension bearing is arranged symmetrically on the basis of rotating shaft thrust disc, the magnetism of mutual component be it is different, to protect Hold the dynamic balance of shaft axial direction;Both ends of the shaft is equipped with sensor, detects the axial displacement and radial displacement of shaft;Driving The motive power of motor offer whole device.
It is outer between axial magnetic suspension bearing and right radial magnetic suspension bearing to add in the length measuring device of the magnetic suspension bearing Electromagnetic damper, electromagnetic damper can achieve the purpose for almost eliminating magnetic suspension bearing vibration.
The utility model has the beneficial effects that
First is that magnetic suspension bearing is not contacted with shaft, friction and loss between bearing and shaft are eliminated, it can be long-term Guarantee the accuracy of scale measurement;
Second is that the influence that the vibration for almost eliminating bearing measures scale;
Third is that improving the service life and maintenance cycle of bearing and shaft, guarantees the fluency of production line, improve metal The production efficiency of pipe.
