Description

Machining device for repairing heavy carrier roller assembly excircle

Technical Field

The utility model relates to a heavy carrier roller repairing device of a cylinder mixer, in particular to a processing device for repairing an assembly excircle of a heavy carrier roller.

Background

Heavy duty rollers are used quite frequently in various industries. For example, the mixing device is one of the main devices of the sintering plant, is arranged between the batching device and the sintering machine, and provides raw materials which are uniformly mixed and suitable for the sintering machine. Most of the prior middle-outer sintering production uses a cylinder mixer, and the cylinder mixer is increased along with the gradual increase of the scale of the sintering machine. Because the two ends of the rotating shaft 04 of the carrier roller 05 are connected with the bearings in the bearing seat 03, the bearings are fixed through the shaft end cover 02 at the outer end of the rotating shaft 04, and the outer end of the bearing seat 03 is provided with a seat end cover 01 (shown in fig. 1), and the bearing seat 03 is fixedly connected with the machine body. Therefore, in the working process of the cylinder mixer, the roller ring contacts and wears with the roller surface of the carrier roller 05 for a long time, so that more pits and pits on the roller surface can be caused. When the roller surface of the carrier roller 05 with serious deformation contacts with the rolling ring, the contact area can be reduced, the mutual transmission can generate blocking, the rotating blocking can be easily caused to work abnormally after the wear is overlarge, the production is seriously influenced, and the roller surface assembled by the carrier roller is urgently needed to be repaired. For the carrier roller 05 with the roller surface diameter smaller than 1000mm, the existing vertical lathe is used for self turning, the bearing seats 03 at the two ends are required to be removed for turning, and oil is required to be filled back after the turning is completed. Meanwhile, because the length of the roller is limited, the roller cannot be completely turned by one-time clamping, and when turning can be performed only after turning and correcting, the repairing process is very complicated and difficult, and a large amount of manpower is wasted. Because the heavy carrier roller is huge in size, the common lathe cannot repair the outer circle of the heavy carrier roller, and repair processing can be performed only through a special machine tool, for example, the cost of purchasing the special machine tool is high, for example, the cost is high and the period is long when a professional manufacturer is entrusted to process the heavy carrier roller.
