Description

Tail shield grease groove processing equipment and system thereof

Technical Field

The utility model relates to the technical field of milling machine processing equipment, in particular to tail shield grease groove processing equipment and a tail shield grease groove processing system.

Background

In the processing process of the tail shield grease groove and the grouting groove, the weight is large due to the large diameter of the workpiece. Therefore, it is difficult for the general apparatus to complete the milling process. The solution currently in common use is to work with large floor-standing boring and milling machines. The floor type boring and milling machine has no movable workbench, and the workpiece is fixed on the floor type platform, so that the floor type boring and milling machine is suitable for processing workpieces with larger sizes and weights. The main shaft box moves vertically on the upright post, and the upright post moves vertically and horizontally on the lathe bed or only moves transversely. The spindle box is internally provided with a ram which can stretch and retract together with the milling shaft, and the section of the ram is rectangular, square, polygonal and the like, and the ram is mainly rectangular. The ram has larger size and higher rigidity, and the ram is used for supporting the main shaft and the mounting accessories, so that the ram is suitable for powerful milling, and the process range can be enlarged and the machining precision can be improved. The boring shaft is arranged in the milling shaft and can be independently telescopic and fed. The floor type boring and milling machine with larger specification is also provided with a high-speed main shaft for drilling. The machine tool is provided with accessories such as a platform, a rotary workbench, a rear upright post, a flat rotating disc, a vertical milling head, a universal milling head and the like. In practical use, the milling workload is generally larger than that of boring, so the milling and boring machine is also called a floor milling and boring machine and is mainly used for heavy machinery factories.

The following problems exist in the process of machining the tail shield shell by adopting a large floor type boring and milling machine: 1. the tail shield shell processed by the large floor type boring and milling machine has the phenomenon of large material and small material, and the processing cost is extremely wasted. In addition, the equipment investment of the large floor type boring and milling machine is extremely large, and general manufacturers cannot purchase the large floor type boring and milling machine in a large scale. 2. When the large floor type boring and milling machine processes the grease groove on the shell, only the feeding of the X axis and the Z axis is realized, and the feeding is extremely wasteful for the non-working of the Y axis. The two points illustrate that the existing processing mode has great optimization and improvement space.
