Embodiment 1

[0033] see figure 1 , figure 2 , a processing method for an ultra-large drum, the method comprises the following steps in turn:

[0034] Machining the drum shaft: using a vertical lathe to process the bearing mounting position 21 located at one end of the drum shaft 2;

[0035] Install the drum body: the drum body 1 includes a plurality of sub-cylinders 11 with equal diameters. When installing, first set a support ring inside the to-be-joined end of the sub-cylinders 11, and then set the adjacent sub-cylinders 11 on the drum Coaxial docking is performed after the outside of axis 2.

[0036] Welding reference block: Use a boring machine to weld the reference block 3 in the center of the side of the drum body 1. The upper and lower reference planes of the reference block 3 are arranged symmetrically with the center of the drum shaft 2. The vertical reference plane of the reference block 3 is aligned with the upper and lower reference blocks. Datum vertical setting;

Abstract

The invention discloses a method for machining an ultra-large roller. A vertical lathe is used for machining a bearing installing position located at one end of a roller shaft, a roller body is arranged outside the roller shaft in a sleeved mode, a boring mill is used for welding a reference block in the center of the side portion of the roller body, the upper reference face and the lower reference face of the reference block and the center of the roller shaft are symmetrically arranged, the vertical reference face of the reference block is perpendicular to the upper reference face and the lower reference face, the boring mill is used for machining a slewing bearing installing position at the other end of the roller body, and taper plates and a connector are correspondingly welded to the two ends and the top of the roller body. The coaxiality of the two ends of the roller is guaranteed, machining investment is reduced, and the application range is widened.

Description

technical field [0001] The invention relates to the processing of rollers, in particular to a method for processing super-large rollers, which is specifically suitable for ensuring the coaxiality of both ends of the rollers, expanding the scope of application, and can be used for processing some large rollers that are not convenient for direct processing. Background technique [0002] The drum is mainly a structure used to store or wind cables, hoses, etc. It cannot work independently. Generally, both sides are supported by a frame, and bearings are installed at the connection between the drum shaft and the frame, so that the drum is driven by power. Free rotation according to design needs. Its main structure is usually cylindrical, with side panels on both sides, allowing multiple layers of winding. [0003] During the rotation of the drum, due to its own or external reasons, such as machining accuracy, installation accuracy, external impact, etc., the two ends of the drum...
