Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] Such as figure 1 It is an embodiment of a quick-change rail milling cutter of the present invention, which includes a base 1 , a cutter ring 2 and a blade 3 . A plurality of blades 3 are arranged in such a way that the cutting part envelops the rail profile 4 to form a group of blades, and a plurality of groups of blades are detachably mounted on the outer circumference of the knife ring 2 along the circumferential direction. A group of blades 3 is det...

Abstract

The invention discloses a quick-changing type steel rail milling cutter which comprises a plurality of blades, a cutter ring and a substrate; the blades are arrayed according to the manner that a cutting part wraps a steel rail outline to form a plurality of grouped blades; the grouped blades are detachably mounted on the outer circumference of the cutter ring in the circumferential direction; thecutter ring is positioned on the substrate through a matching part and is detachably mounted on the outer circumference of the substrate; and a driving part for transmitting torque to synchronously rotate the substrate and the cutter ring is arranged between the substrate and the cutter ring. The quick-changing type steel rail milling cutter has the benefits of being simple in structure, quicklydetaching and changing the blade through one person, improving the efficiency, and being high in positioning and mounting precision, and low in cost and wide in application range.

Description

technical field [0001] The invention relates to a milling cutter structure, in particular to a quick-change rail milling cutter. Background technique [0002] In recent years, with the rapid development of rail transit, with the increasing speed, heavy load and frequency of departure, the use of rails is deteriorating. Cross-sectional defects such as fatigue cracks, spalling, fat edge, etc. and longitudinal section defects such as wave wear are prone to occur on the surface of the rail. Changes in rail profile and smoothness have an important impact on driving safety, comfort and economy. In order to improve the wheel-rail relationship, prolong the life of the rail, improve the economy and safety, repairing the rail is a commonly used method at home and abroad. [0003] The rail milling and grinding car is a new technology developed in recent years. The rail milling and grinding car uses the method of circumferential milling to process the rails. It uses several sets of mi...
