Background

The existing slip ring is a combination of a collector ring, a slip ring and a carbon brush; a mechanical reed slip ring; a mercury slip ring; wireless slip rings, and the like. The slip rings have the defects of dust accumulation of carbon powder, easy abrasion, limited installation space, limited service life, complicated subsequent maintenance and the like when the device rotates. Especially, the high rotating speed cannot be used at the working rotating speed, the normal work can be carried out only at dozens of revolutions per minute to hundreds of revolutions, the working state is very unstable after thousands of revolutions per minute, the abrasion of parts is serious, and further, the stability is poor under the working condition of tens of thousands of revolutions per minute, and the parts are seriously abraded to cause the device to be damaged and unusable. Therefore, under the working condition that an ultrahigh rotating speed (more than 10000 rbm/min) must be used, no slip ring capable of meeting the performance is available at present. In particular, some superhard material processing requires ultra-high rotating speed for processing, and some devices with low rotating speed cannot efficiently process and form and cannot achieve the accurate size. Therefore, a slip ring rotating conductive device which can stably run at ultrahigh rotation speed (more than 10000 rbm/min) and low rotation speed (less than 10000 rbm/min), has small part abrasion, occupies small space during installation and has low maintenance cost is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a rotatory electric installation of sliding ring solves current sliding ring and revolves electric installation of transduction and moves the steady difference, part wearing and tearing greatly under the super high commentaries on classics (10000 rbm/per minute more), and occupation space is big during the installation, the problem that the maintenance cost is high.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a rotatory electric installation of sliding ring, includes the fixing base be provided with the bearing in the fixing base, be provided with the pivot on the rotatory axis of bearing, the rotatory axis of pivot is on a straight line with the rotatory axis of bearing, still be provided with at least one first locating piece between fixing base and the bearing, first locating piece and fixing base, bearing fixed connection, still set up at least one second locating piece between bearing and the pivot, all set up the passageway of parcel conducting material in fixing base, first locating piece, second locating piece, the pivot, the passageway set up one at least.

Preferably, the conductive material may be: wires, conductive metals, conductive rubber, conductive plastics, and the like.

Preferably, the first positioning block and the second positioning block are made of insulating materials.

Furthermore, first locating block and fixing base, bearing complex one side, the connected mode can be that to splice or weld or threaded connection or joint mode is connected, makes first locating block, fixing base, bearing three fixed together.

Furthermore, the second positioning block is connected with the rotating shaft and the bearing at one matched surface in a gluing or welding or threaded connection or clamping connection mode, so that the second positioning block, the rotating shaft and the bearing are fixed together.

The utility model has the advantages that: through being provided with the bearing in the fixing base, utilize the roll and the electrically conductive characteristic of bearing itself, make the device operate stable by a wide margin improvement, part wearing and tearing reduce by a wide margin under the super high commentaries on classics (more than 10000 rbm/per minute) to occupation space is less, maintenance cost is lower during the installation. The slip ring rotating conductive device is suitable for multiple purposes, particularly for power transmission of a high-voltage variable-frequency power supply like ultrasonic spindle processing, and can improve the reliable stability of an ultrasonic driving power supply under the ultrahigh rotating speed of a spindle. The loss and the rotating speed limit of the carbon brush slip ring are reduced, and the defects of complex installation design, limited power and the like of the wireless slip ring are avoided. The ultrahigh rotating speed operation under various special working conditions becomes possible.

The present invention will be described in more detail with reference to the accompanying drawings and examples.
