Abstract

The invention provides a polishing device. The polishing device is used for polishing a to-be-polished piece, and is provided with a scheduled operating center line. The polishing device comprises a rack and a grinding mechanism; the grinding mechanism is arranged on the rack; the grinding mechanism comprises a rotating disc and grinding wheels; the grinding wheels are rotatably arranged around the axis of the grinding mechanism; a first through hole through which the to-be-polished piece penetrates is formed in the rotating disc; the center line of the first through hole coincides with the scheduled operating center line; the grinding wheels are connected with the rotating disc; the grinding wheels are movably arranged in the radial direction of the rotating disc so as to be close to or far away from the to-be-polished piece; the rotating disc is rotatably arranged around the scheduled operating center line so as to drive the grinding wheels to rotate around the to-be-polished piece,so that the to-be-polished piece is circumferentially ground; and the grinding mechanism is movably arranged in the extending direction of the scheduled operating center line so as to drive the grinding wheels to axially grind the to-be-polished piece. According to the polishing device, the problem that the polishing efficiency of a high voltage cable terminal is relatively low in the prior art issolved.

Description

Technical field [0001] The invention relates to the technical field of vehicles, and in particular to a polishing device. Background technique [0002] EMUs have gradually become the best way for short- and medium-distance travel at present, which has further shortened the distance and development between cities. As the speed of EMUs increases, the traction power of trains has gradually increased. The process of electric energy transmission is particularly critical, especially from contact Single-phase 25kV, 50Hz high-voltage power directly received by the network. The high-voltage parts to be polished on the train serve as the connection between the pantograph, high-voltage equipment and the traction transformer, and are the main trunk line for vehicle power transmission. Once a failure occurs, the vehicle will inevitably lose power and wait for rescue. [0003] At present, the processing and assembling process of the terminal of the high-pressure part to be polished is very comp...
