TECHNICAL FIELD

[0001] The present application relates to the technical field of scraper conveyor, in particular to a processing tool for positioning and clamping tail live upper edge and a tail live upper edge processing method. BACKGROUND

[0002] Tail live upper edge is an important part of the telescopic tail of the scraper conveyor, which is responsible for controlling and changing the running track of the scraper chain. Since its position is exactly where the scraper chain is lifted, the scraper chain is worn faster than other parts due to friction. In order to quickly replace and ensure better meshing of the scraper chain and the sprocket, the tail live upper edge is designed to be detachable.

[0003] The tail live upper edge is a multi-segment arc combination or a large-diameter arc structure, and the reference plane is small. When processing the connecting hole and the pin hole, there is not enough reference plane available, so during the processing, the hole and the hole of the tail frame body cannot be aligned and assembled. Correspondingly, the running gap and the running track of the scraper chain cannot achieve the design intention, which affects the smoothness of the meshing of the scraper chain and the sprocket, aggravates the wear of the scraper, and even causes the scraper to be unable to pass through.
