Abstract

The invention provides a roller sealing device of a chip removal machine. The roller sealing device is used for solving the technical problems that in the existing technology, end face water sealing,packing and other sealing elements are adopted, elasticity is lost due to ageing, consequently, sealing is invalid, cutting liquid obtained after filtering contains a large number of cutting chippings, a machine tool pipe is blocked, and a cutter is additionally abraded. Main structures of the sealing device comprise a movable ring, a convex ring arranged on the movable ring, a fixed ring and a cover plate, an annular cavity is formed among the above components, a pipe threaded hole is formed in the fixed ring, the pipe threaded hole is connected with a high pressure connector, the high pressure connector communicates with the annular cavity, the sealing function of the sealing device is achieved through the pressure difference and the sealing structure comprehensively, and the problem that the roller device is invalid in sealing is solved. In addition, the invention provide a roller of the chip removal machine and the chip removal machine, and the roller and the chip removal machine both use the structure and the working principle of the above roller sealing device.

Description

technical field [0001] The invention relates to the field of machine tool processing, in particular to a sealing structure for a drum device of a chip removal machine. Background technique [0002] The drum type chip conveyor is used to deal with chips and cutting fluid produced by machine tool processing. Scraper or chain plate is used to separate the chips from the cutting fluid and then discharged. The drum filter device is used to filter the cutting fluid and return it to the machine tool for reuse. separated. At present, the drum-type chip removal machine mostly uses sealing elements such as end face water seals and packing to realize the sealing function. Due to the flow direction of the cutting fluid, there are a lot of chips at the position of the drum, and the wear of end face water seals, packing and other components will inevitably cause wear. In addition, the cutting fluid will also cause the end face water seal, packing and other sealing elements to age and lo...
