Medium and low speed magnetic levitation F-rail machining forming cutter and axial adjusting method of forming cutter

Abstract

The invention relates to a medium and low speed magnetic levitation F-rail machining forming cutter which is used for machining the magnetic levitation F-rail surface by once and is high in machiningprecision. The medium and low speed magnetic levitation F-rail machining forming cutter comprises an F-rail; a first forming disc milling cutter, a second forming disc milling cutter and a third forming disc milling cutter are connected together through a cutter shaft in series, and a first spacer bush is arranged between the first forming disc milling cutter and the second forming disc milling cutter; and a second spacer bush is arranged between the second forming disc milling cutter and the third forming disc milling cutter, a positioning sleeve is located on the cutter shaft and is used forpositioning the third forming disc milling cutter, a pressing sleeve sleeves the cutter shaft and tightly presses the first forming disc milling cutter, and then the first forming disc milling cutteris positioned by a screwing round nut which is screwed on the cutter shaft. The forming cutter and the axial adjusting method have the advantages that firstly, the machining efficiency is greatly improved, the F-rail three-time milling forming design in the background technology is designed into one-time milling forming, so that a large amount of time is saved; and secondly, the machining shape,the size and the relative position requirement of the F-rail machining surface are completely ensured by virtue of the shape and the position relation of the three cutter discs, the error of the cutter setting during repeated machining is avoided, and the machining precision requirement is reliably and effectively ensured.

Description

technical field [0001] The invention relates to a medium-low speed maglev F-rail machining forming tool and an axial adjustment method for the forming tool, which is formed by one-time processing of the maglev F-rail surface and has high machining accuracy, and belongs to the field of manufacturing special-purpose processing tools for the F-rail. Background technique [0002] The F rail is the main functional part of the medium and low speed maglev track, and the rolled F-shaped steel needs to be machined to meet the functional requirements of the F rail. The cross-sectional shape and requirements of the F rail are as follows: image 3 As shown, it is used to process the 1, 2, and 3 sides of the F rail, such as image 3 shown. The existing processing method is to use an angled special rod milling cutter to respectively process the 1, 2, and 3 surfaces ( image 3 ) for processing, such as Figure 4 , Figure 5 , Image 6 shown. 1, 2, 3 sides ( image 3 ) requires three pa...
