Abstract
A kind of tread milling cutter of railroad rail, the cutter hub of milling cutter is in the form of annular discs, center is provided with the axis hole for installing, the edge of cutter hub is provided with the annular flange flange tilted laterally, the top of annular flange flange is curved, and is evenly provided with milling cutter group, and described milling cutter group is made up of four slitting milling cutter blades, four slitting milling cutter blades are arranged in order setting respectively by plum blossom screw along the radial direction of cutter hub, stagger in two the adjacent positions of milling cutter group in annular flange flange.The utility model is rational in infrastructure, can be shaping to guide pass time processing, avoids repeatedly processing the problem causing precision to reduce, and processing technology is simple, and efficiency is high.
Description
Technical field
The utility model relates to a kind of milling cutter, specifically a kind of tread milling cutter of railroad rail.
Background technology
In the processing of railroad rails, milling cutter is absolutely necessary machining tool.Due to the particularity of railroad rails shape, each face of guide rail needs the milling cutter of multiple different forming surface through repeatedly Milling Machining, and process is complicated.Further, easily impact previous machined surface when secondary Milling Machining, cause overall processing precision wayward, difficulty of processing is high, complex process, and working (machining) efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tread milling cutter of railroad rail, has easy to process, one-shot forming, the advantage that working (machining) efficiency is high.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of tread milling cutter of railroad rail, the cutter hub of milling cutter is in the form of annular discs, center is provided with the axis hole for installing, the edge of cutter hub is provided with the annular flange flange tilted laterally, the top of annular flange flange is curved, and be evenly provided with milling cutter group, described milling cutter group is made up of four slitting milling cutter blades, four slitting milling cutter blades are arranged in order setting respectively by plum blossom screw along the radial direction of cutter hub, stagger in two the adjacent positions of milling cutter group in annular flange flange.
The beneficial effects of the utility model are: rational in infrastructure, can be shaping to guide pass time processing, avoid repeatedly processing the problem causing precision to reduce, and processing technology is simple, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Mark in figure: 1, cutter hub, 2, milling cutter group, 3, plum blossom screw.
Detailed description of the invention
As shown in the figure, a kind of tread milling cutter of railroad rail, the cutter hub 1 of milling cutter is in the form of annular discs, center is provided with the axis hole for installing, and the edge of cutter hub 1 is provided with the annular flange flange tilted laterally, and the top of annular flange flange is curved, and be evenly provided with milling cutter group 2, described milling cutter group 2 is made up of four slitting milling cutter blades, and four slitting milling cutter blades are arranged in order setting respectively by plum blossom screw 3 along the radial direction of cutter hub 1, stagger in two the adjacent positions of milling cutter group 2 in annular flange flange.
The utility model is rational in infrastructure, can be shaping to guide pass time processing, avoids repeatedly processing the problem causing precision to reduce, and processing technology is simple, and efficiency is high.
