[0002] Rails are an important part of the railway transportation system. Rails can evenly distribute the weight of the train, greatly improving the train's load-bearing capacity. The quality and geometry of rails have an important impact on the safety and comfort of railway transportation. In the production and maintenance of rails, milling is often required to ensure that the geometry and surface quality of the rails meet the requirements. In the rail milling process, positioning and clamping is a key link, which directly affects the accuracy and stability of the milling process.

[0003] Most of the existing clamping methods are mechanical fixing and magnetic fixing. Magnetic fixing can reduce the extrusion on the surface of the rail, reduce the deformation of the rail during processing, and improve the flatness after processing. However, there are some shortcomings in the actual processing of the rail by magnetic processing. Since magnetic clamping has no mechanical mechanism, it is difficult to adjust the position of the rail, and multiple tool adjustments are required during processing, which affects the processing efficiency. In addition, since the operating tables of different machine tools are of different sizes, magnetic clamps are difficult to adapt to machine tools of different sizes. Utility Model Content

[0023] The magnetic chuck 2 is mounted on the base 1, and the sliding block 4 can slide in the slide groove 3, so that the notch on the sliding block 4 can be aligned with the fixed groove 5 on the base 1, so as to adapt to bases 1 of different widths. After the two are aligned, the sliding block 4 and the fixed groove 5 can be fixed together using bolts, so as to fix the magnetic chuck 2 on the base 1. When the mounting block 6 is needed, the mounting block 6 can be installed on one side of the magnetic chuck 2, and the threaded rod 7 can drive the push plate 8 to move on the surface of the magnetic chuck 2, so as to adjust the position of the rail placed on the surface of the magnetic chuck 2. The magnetic chuck 2 of the utility model is a permanent magnetic chuck or an electromagnetic chuck. Since the permanent magnetic chuck does not require external power supply, it has lower energy consumption than the electromagnetic chuck, and there will be no problem of electrical breakdown and short circuit caused by improper use environment, and the rail processing will not be unable to be carried out due to power failure, so as to ensure the reliability of the rail processing positioning clamping device of the utility model. Therefore, the magnetic chuck 2 of this embodiment is preferably a permanent magnetic chuck.

A reinforcing rib is provided on the back of the support plate 11 to increase the strength of the support plate 11 and reduce the possibility of deformation. The compression spring 15 pushes the sleeve 13 to move to one side, so that the guide wheel 14 outside the sleeve 13 is against the outer surface of the processed rail, which plays an auxiliary fixing role and reduces the shaking of the rail.

The corresponding replacement block 19 can be installed according to different needs to adjust the size of the push plate 8.
