Embodiment 1

[0014] Embodiment 1: with reference to attached figure 1 . A medium-low speed maglev F-track magnetic pole surface and detection surface processing tool at the same time, the F-rail magnetic pole surface milling cutter tool 11 and the detection surface milling cutter tool 12 cutter bodies are integral cutter bodies in which the bottom end surface of the upper cutter body is larger than the upper end surface of the lower cutter body 1. Install magnetic pole face milling cutters 13 on both sides of the bottom of the upper cutter body, and install detection face milling cutters 14 on both sides of the bottom of the lower cutter body. The distance H between the processing surfaces of the magnetic pole face milling cutter 13 and the detection face milling cutter 14 is equal to the magnetic pole surface to The distance of the detection surface, that is, the distance between the magnetic pole face milling cutter 13 and the detection face milling cutter 14 is equal to the distance H ...

Embodiment 2

[0015] Embodiment 2: On the basis of Embodiment 1, the F-track magnetic pole face milling tool 11 is superimposed on the detection face milling tool 12 and the (upper) F-rail magnetic pole face milling tool 11 and the (lower) detection face milling tool are passed The position and size relationship of the holes and keys between the tools 12 connect the two cutters and fasten them with bolts or other methods to form a whole. At this time, the magnetic pole face milling cutter 13 and the detection face milling cutter 14 are installed on the cutter body. The magnetic pole face milling cutter 13 processes the magnetic pole face, and the detection face milling cutter 14 processes the detection face, so that the magnetic pole face and the detection face are processed simultaneously, and the distance between the magnetic pole face milling cutter 13 and the detection face milling cutter 14 is equal to the distance from the magnetic pole face to the detection face .

Abstract

The invention relates to a tool capable of simultaneously machining the magnetic pole face and the detection face of a medium- and low-speed magnetic levitation F rail. The tool is characterized in that the tool bodies of an F rail magnetic pole face milling tool and a detection face milling tool are integrated into an integral tool body with the bottom end face of the upper tool body being largerthan the upper end face of the lower tool body, magnetic pole face milling cutters are mounted on two sides of the bottom of the upper tool body, detection face milling tools are mounted on two sidesof the bottom of the lower tool body, and the distance H between a magnetic pole face milling cutter machining face and a detection face milling cutter machining face is equal to the distance betweenthe magnetic pole face and the detection face. The tool has the advantages that machining efficiency is doubled; the problems that the magnetic pole face and the detection face are machined separately in an original machining, two-step machining is needed, and cutter replacement or machine tool replacement is needed during the machining are solved; by the combined tool, the magnetic pole face andthe detection face can be machined simultaneously, cutting feeding time of another machining is saved, and cutter replacement is not needed during the machining; the dimension H from the magnetic pole face to the detection face is guaranteed by the dimension of the combined tool, cutter alignment errors during two-step machining are avoided, and the dimension precision requirements from the magnetic pole face to the detection face are guaranteed reliably and effectively.

Description

technical field [0001] The invention relates to a medium-low speed maglev F-rail magnetic pole surface and detection surface simultaneous processing tool which can simultaneously process the F-rail magnetic pole surface and the detection surface during F-rail machining, and belongs to the field of F-rail processing tool manufacturing. 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 rail row. The cross-sectional shape and requirements of its F rail are as follows: figure 2 As shown in the figure, plane 1 and plane 2 are coplanar, that is, the magnetic pole plane; plane 3 in the figure is the detection plane. The common processing method of F rail is to use two tools to process the magnetic pole surface and the detection respectively. Such as Figure 3-4 as shown, image 3 A schematic diagram of the processing of the m...
