Double-piece independent wire guide wheel

Abstract

The invention relates to a device for precision winding and wiring and in particular discloses a double-piece independent wire guide wheel. The double-piece independent wire guide wheel comprises a gas guide end cover, an upper guide wheel piece, a plane bearing, a lower guide wheel piece and a threaded shaft, wherein outer rings of the upper guide wheel piece and the lower guide wheel piece are coated by polyurethane rubber rings; the upper guide wheel piece is connected with the lower guide wheel piece through the plane bearing; ball roller bearings are respectively arranged on the upper guide wheel piece and the lower guide wheel piece; and the threaded shaft penetrates through the gas guide end cover, the upper guide wheel piece, the plane bearing, the lower guide wheel piece and central holes of the ball roller bearings, so that the gas guide end cover, the upper guide wheel piece, the plane bearing, the lower guide wheel piece and the ball roller bearings are fixedly connected. According to the double-piece independent wire guide wheel, the problem that the conventional integral multi-slot type wire guide wheel is often scrap is solved, the production cost of an enterprise is effectively reduced, and the double-piece independent wire guide wheel has the advantages of high practicality, low cost, small size and the like.

Description

technical field [0001] The invention relates to a device for precision winding and wiring, in particular to a guide wheel. Background technique [0002] In the past, most of the wire wheels used for cutting polysilicon cores have multiple grooves on one wheel. However, during the cutting process, the diamond wire in the wire groove must always maintain a certain tension during the cutting process (to ensure the needs of normal cutting and the wire will not be broken), and the constant tension system controls the tension of the tension arm. Swing position to ensure constant tension of diamond wire. This results in that the speed of the guide wheel at the tangent point of the diamond wire at the inlet and outlet ends is not at the same speed when the tension is adjusted, so that the diamond wire will slide in the wire groove; even in a certain An instant in the complete opposite direction. Since these grooves are located on the same wheel, the end result is that the diamond...
