Description
Technical field
The utility model relates to a kind of boring PRESS PLUNGER semi arch servicing unit, belongs to processing apparatus technical field.
Background technology
Large-scale straight side press guide pillar semi arch size is larger, arc surface is dark, dimensional accuracy and surface smoothness require very high, traditional processing method and machining tool are difficult to guarantee these requirements, traditional processing method is: on the knife bar of facing head, fill white steel knife, with white steel knife boring arc surface, arc surface with white steel knife right boring, fineness only reaches 3.2, far be not by far up to the mark, traditional processing method and machining tool cannot meet the demands at all, want to process the satisfactory guide pillar of dimensional accuracy and surface smoothness, must separately ward off new footpath.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of boring PRESS PLUNGER semi arch servicing unit, and guide pillar semi arch dimensional accuracy and the surface smoothness of processing can meet the requirements.
To achieve these goals, the technical solution adopted in the utility model is: a kind of boring PRESS PLUNGER semi arch servicing unit, comprise boring bar and broach shell, boring bar one side is driving end, opposite side is support end, and boring bar driving end is connected with boring machine, and boring bar middle part offers fixing hole, broach shell is connected with boring bar by holding screw through fixing hole, is installed with fine boring cutter in broach shell.
Further, also comprise fairlead, fairlead is enclosed within the support end place of boring bar.
Further, fine boring cutter is arranged in broach shell by screw.
Compared with prior art: the utility model utilizes boring and milling machine to drive fine boring cutter to process guide pillar semi arch, and stable in process, precision and the fineness of processing are higher.
