Embodiment 1

[0078] like Figure 1 to Figure 5 As shown, the embodiment of the present invention provides a combination tool for online milling of rails, including a cutter head assembly, the cutter head assembly is connected to a driving device, and a cutting element is provided on the cutter head Assemblies, in order to realize the forming processing of different areas on both sides of the center line of the top surface of the rail 4.

[0079] like Figure 1 to Figure 5 As shown, the cutterhead assembly includes at least two cutterheads, wherein the cutterhead assembly includes a first main cutterhead 1 and a second main cutterhead 2, and the first main cutterhead 1 and the second main cutterhead 2 have the same structure , and symmetrical to both sides of the centerline of the top surface of the rail 4 rails.

[0080] In the embodiment of the present invention, the cutting element is a cutting blade, especially a cemented carbide milling cutter. After the cutter head assembly is insta...

Embodiment 2

[0093] Such as Image 6 with Figure 7 As shown, the embodiment of the present invention provides a combined tool for rail online milling, the same as embodiment 1, the difference is that: the first cutter base 101 and the second cutter base 201 are respectively the same as the The above-mentioned third cutter head base 301 is integrally formed, the structure is more compact and the connection strength can be improved, making the structure stronger.

Abstract

The invention relates to a combined tool for online milling of a steel rail. The combined tool comprises a cutter component, and the cutter component is connected with a driving device; the combined tool further comprises a cutting part; and the cutting part is arranged on the cutter component to realize forming processing of different regions on both sides of the center line of the rail top surface of the steel rail (4). The combined tool for the online milling of the steel rail provided by the invention solves the problems of self-excited vibration during the use of an existing tool, cumbersome adjustment process of the tool and low economic efficiency of the use of blades and the like, and improves the efficiency of on-site operations.

Description

technical field [0001] The invention relates to the technical field of forming cutters for repairing rail contours, in particular to a combined cutter for on-line milling of rails. Background technique [0002] Rail is one of the key factors to ensure the safety of rail transit operation. With the long-term, frequent, and complex interaction between the wheel and rail, defects such as cracks, fat edges, and wavy wear will occur on the surface of the rail, which will affect the train running process. adversely affect the safety, stability and comfort in the vehicle. Therefore, we need to repair the worn rail by milling. Currently, the commonly used repair methods are: rough milling + fine milling or rough milling + grinding. The main purpose of fine milling or grinding is to remove the connecting tool left by rough milling. Ribs improve the smoothness of the rail. At present, the existing fine milling cutter adopts wide-edged blade forming milling. Based on the standard rai...
