Abstract

The invention discloses a surface milling machining tool for a flange bearing part, and belongs to the technical field of part positioning fixed tools. The surface milling machining tool includes a tool base, a compressing part is arranged on one side of the tool base, first main body locating holes are symmetrically formed in the upper end and the lower end of the front surface of the tool base,a first positioning part is arranged on the front surface of the tool base, and first clamping parts are symmetrically arranged on the upper side and the lower side of the first positioning part; second main body positioning holes are symmetrically formed in the upper end and the lower end of the back surface of the tool base, a second positioning part is arranged on the back surface of the tool base, and a second clamping part is arranged on the second positioning part; and a plurality of drill head guiding holes are further formed in the upper end of the back surface of the tool base. The surface milling machining tool for the flange bearing part has the beneficial effects that positioning and fixing of the flange bearing part are simple, convenient and efficient, machining quality of asurface milling is effectively guaranteed, coaxiality of the hole structure on the flange bearing part is effectively guaranteed, and damage on the edge strip of the flange bearing part is avoided.

Description

technical field [0001] The invention belongs to the technical field of part positioning and fixing tooling, and in particular relates to a milling tool for flange bearing parts. Background technique [0002] With the increase of foreign subcontracting projects, the number of small and medium-sized die forging and casting parts of foreign civil aircraft continues to increase, and the digital processing efficiency of die forging and casting parts has been significantly improved. However, due to the lack of processing experience in die forging and casting parts, aviation manufacturing units have low processing efficiency and low processing quality for such parts. Therefore, it is imminent to solve the processing efficiency of such parts and rapidly improve the processing quality of parts. At present, the number of small and medium-sized die forging and casting parts in aviation manufacturing units continues to increase. During the processing of casting flange bearing parts, du...
