The utility model relates to rail head profile milling cutters, it is characterized by: it includes cutter hub and cutting tip (3), cutter hub is made of left cutter hub (1) and right cutter hub (2), blade bearing is provided on left cutter hub (1) and right cutter hub (2), cutting tip (3) is fixedly connected on corresponding blade bearing, and one week uniformly distributed array, cutting tip is complete and is continuously fitted rail head of rail molded line.The utility model provides a kind of rail head profile milling cutter that machining accuracy and processing efficiency can be improved.

Description

Rail head profile milling cutter
Technical field
The utility model relates to metal cutting fields, especially rail head profile milling cutter.
Background technique
The processing method of railroad turnout steel rail rail head mainly uses vertical processing at present, due to the unilateral maximum processing of vertical processing Range can only arrive rail top center highest point, so need to separately process rail head two sides, process rail head side contoured surface, then Rail head other side contoured surface is processed, which is easy in-orbit both sides of head and generates symmetry error, also due to tool-setting error Entire rail head dimensional accuracy is influenced, meanwhile, two sides separate machined is also required to consume more process times.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, providing one kind can be improved machining accuracy and processing effect The rail head profile milling cutter of rate.
The purpose of this utility model is achieved through the following technical solutions:
Rail head profile milling cutter, it includes cutter hub and cutting tip, and cutter hub is made of left cutter hub and right cutter hub, left cutter hub and the right side Blade bearing is provided on cutter hub, cutting tip is fixedly connected on corresponding blade bearing, and one week uniformly distributed array, cutting tip are complete Whole and continuous fitting rail head of rail molded line.
Further, the cutter hub is by numerically-controlled machine tool machine-shaping.
Further, the cutting tip is connected on corresponding blade bearing by housing screw.
The utility model has the advantage that, using horizontal processing method, the structure of left and right cutter hub combination, cutting tip is complete The entire rail head of whole and continuous fitting, can disposably cut out the type face of rail head of rail, the transition of type face is round and smooth, processing efficiency Height, without polishing after processing, so that surface to be machined molded line precision is high, surface transition is round and smooth.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
In figure: the left cutter hub of 1-, the right cutter hub of 2-, 3- cutting tip, 4- housing screw.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to It is as described below.
As shown in Figure 1, rail head profile milling cutter, it includes cutter hub and cutting tip 3, and cutter hub is by left cutter hub 1 and 2 groups of right cutter hub At, blade bearing is provided on left cutter hub 1 and right cutter hub 2, cutting tip 3 is connected on corresponding blade bearing by housing screw 4, And one week uniformly distributed array, cutting tip 3 is complete and continuously fitting rail head of rail molded line, cutter hub are completed the process by numerically-controlled machine tool, knife Piece firm position is reliable, and cutting tip is formed by cutting molded line precision height, so that machining accuracy and the equal energy of processing efficiency It effectively improves.
