Abstract

The invention discloses a horizontal roller smoothing processing device of a universal mill and a processing method thereof, and belongs to the technical field of surface processing of shaft and roller parts. In the horizontal roller smoothing processing device of the universal mill and the processing method thereof provided by the invention, an abrasive belt grinding device is installed on the existing equipment such as a lathe to realize the lathe instead of grinding, so as to solve the problems of high purchase cost and large floor space of the grinding machine. The abrasive belt grinding device comprises a transmission wheel and a support wheel, wherein the outer surface of the transmission wheel is provided with protrusions, which play an arc centering role for the abrasive belt; bothends of the support wheel are coaxially equipped with baffle rings, and the outer diameter of the baffle rings is larger than the outer diameter of the support wheel tread, so as to play the role ofpreventing the belt from coming off. When working, the abrasive belt grinding device is installed on the tool rest of the machine tool, and the motor is started to drive the transmission wheel to rotate, and then drive the support wheel to rotate through the abrasive belt, so that the abrasive belt can evenly grind the workpiece, and the level of tightness of the abrasive belt is adjusted by moving a support frame.

Description

technical field [0001] The invention relates to the technical field of surface processing of shafts and rolls, and more specifically relates to a finishing device and a processing method for a horizontal roll shaft of a universal rolling mill. Background technique [0002] The surface finish of large shafts and rollers is relatively high. Generally, it is required to leave a margin of 0.15-0.2mm on one side of the lathe for processing, and then turn it to a grinding machine for grinding to meet the design requirements. Machinery factories generally do not purchase large-scale grinding machine equipment. Large-scale grinding machines have a single purpose and can only be used for grinding; and the purchase cost of grinding machines is relatively high, and the floor space is relatively large. [0003] The range of abrasive belt grinding is much wider than that of grinding wheel grinding machines. All large-scale planes and difficult-to-process materials that cannot be ground b...
