Round blade repair machine

Abstract

The invention relates to a precision hard turning round blade repair machine. A main lathe bed is composed of trapezoidal sliding guide rails and a headstock, a sliding plate capable of adjusting the grinding angle is installed under the headstock, a precision hollow work-piece main shaft is installed in the headstock, a manual pull rod spring clamping device is installed on the hollow main shaft, and the main shaft is connected to a speed reduction motor for lowering the rotation speed. A large supporting plate is arranged on the two trapezoidal sliding guide rails of the lathe bed, and the large supporting plate, an operating crank and a screw rod form an axial feed mechanism of the repair machine, wherein the operating crank and the screw rod are installed on a tailstock. A small supporting plate is installed on a dovetail guide rail of the large supporting plate and is provided with a screw rod through a nut, and the small supporting plate, a screw rod base and an operating crank form a radial feed mechanism, wherein the screw rod base and the operating crank are installed on the large supporting plate. The small supporting plate is provided with an electric spindle, a bowl-shaped diamond grinding wheel with an aluminum main body is clamped in a nut locking mode, the end face of the grinding wheel is used for grinding the negative chamfer of a round blade, and the end face slope of the blade and the outer diameter part can form a new and sharp cutting edge. The repair machine is suitable for repairing round blades made of cubic boron nitride, ceramic or alloy.

Description

technical field [0001] The invention belongs to the field of mechanical processing and relates to a circular blade repairing machine. Background technique [0002] At present, the existing hard turning blade repair equipment is expensive and not domestically produced, and the import price is more than 2 million yuan; and to solve the problem of hard turning instead of coarse grinding in bearing processing and other fields, the high cost of blades restricts the use and development of new technologies. In the field of bearing and related hardened steel processing, there are many hard turning and hard milling instead of roughing or finishing. Many cubic boron nitride and ceramics and other circular machine clip blades are used. Because the blades are expensive, the processing is increased. Costs affect the promotion of new technologies. For this purpose, a precision circular blade repair machine was designed and manufactured. The used blade can be repaired 1-2 times, which red...
