Device for machining F-shaped steel used in track skeleton for magnetic levitation train

Abstract

The invention relates to a device for machining F-shaped steel used in a track skeleton for a magnetic levitation train. The F-shaped steel comprises a wing plate, an inner pole plate and an outer pole plate, wherein the outer side of the outer pole plate is an outer point angle. The device is characterized by comprising a center mould block, a horizontal bracket and a vertical bracket, wherein the horizontal bracket and the vertical bracket are fixedly connected and perpendicular to each other; the horizontal bracket is fixed with the center mould block; a stop collar with a bolt hole is formed on the center mould block; a side plate is arranged on the center mould block; a fastening rod used for fastening is arranged on the side plate; and the distance between the side plate and the vertical bracket is greater than or equal to the width of the F-shaped steel. According to the invention, the device for machining the F-shaped steel can be used for machining a bolt hole group with the dimensions and the locations meeting the requirement rapidly and effectively; the direct measurement and location during machining are avoided; and the resource waste, the high cost and the maximum error in machining caused by adopting large devices are avoided. The machining device has the advantages of simple structure, convenience in operation, and high efficiency.

Description

technical field [0001] The invention relates to an F-shaped steel processing device for a rail bar of a magnetic levitation train, more specifically, an F-shaped steel processing device for a rail bar of a magnetic levitation train that can quickly and accurately process bolt hole groups. Background technique [0002] Maglev transportation is a brand-new transportation mode different from traditional railways, highways, and aviation. It has a series of characteristics such as low noise, small vibration, no pollution, strong line adaptability, and easy implementation. It is safe, reliable, and environmentally friendly. A new type of urban rail transit system, many cities in China have studied the use of low-speed maglev transportation technology to solve urban traffic problems. The rail row of medium and low-speed maglev trains is assembled by connecting F-shaped rails with bolts through sleepers to form a rail row, and then the rail row is installed and fixed on the bridge ...

AI Technical Summary

Problems solved by technology

[0003] Gauge L and leveling point (the center position of the connecting bolt group between the sleeper and the F-type guide rail) are important parameters for the manufacture of the rail row, which are determined by the processing and adjustment of the bolt hole group connecting the F-type rail and the sleeper. Requirements, the size requirement is set as the space size, during the manufacturing process, the rail row bolt hole group cannot be directly measured and processed

The use of large-scale CNC equipment for processing and production results in waste of resources, high costs, and large processing errors
