Abstract

The invention discloses a rail jaw refiner of a rocket sled sliding rail welding connector. The rail jaw refiner comprises a fixed base fixedly installed on the rocket sled sliding rail welding connector and a straight-direction grinding machine arranged on one side of a rocket sled sliding rail and used for grinding a rail jaw of the rocket sled sliding rail welding connector. The upper surface of a grinding wheel of the straight-direction grinding machine is bonded to the rail jaw of the rocket sled sliding rail welding connector, a transverse adjusting mechanism capable of moving transversely along the rocket sled sliding rail is installed on the fixed base and is connected with a vertical adjusting mechanism used for driving the straight-direction grinding machine to move vertically along the rocket sled sliding rail, and the vertical adjusting mechanism is connected with the straight-direction grinding machine through a height adjusting mechanism used for driving the straight-direction grinding machine to move vertically. The rail jaw refiner of the rocket sled sliding rail welding connector is high in automation degree, simple to process and convenient to use, saves cost and has wide popularization and application value in laying of rocket sled sliding rail jointless tracks.

Description

technical field

[0001] The invention relates to a refiner, in particular to a rail jaw refiner for welding joints of rocket sled slide rails. Background technique

[0002] The traditional grinding of welded joints of railway rails mainly uses a rod grinder for rough grinding, and then uses a profile grinder to profile the rail head and working edge. There is no requirement in the standard to grind the rail jaw, so there is no corresponding equipment in this regard . The rocket skid slide rail mainly carries the rocket skid running at high speed on it, and has very strict requirements for rail acceptance, among which the straightness of the rail jaw of the special "I"-shaped rail is required to be ±0.1mm. The traditional rod grinder cannot precisely control the amount of grinding and the shape of the grinder, and the work efficiency is low. The profiling grinder can only grind the working surface, but cannot grind the rail jaw. Therefore, it is urgent to develop a set of hig...
