Abstract

The invention discloses a multi-channel rotary joint device, and belongs to the field of machine tool components. An existing multi-channel rotating device has the defects of inconvenient assembly, disassembly and maintenance due to large sizes. According to the device, by means of air path channels arranged on a supporting shaft, a mandrel and a coupling seat, the mandrel is fixed relative to thesupporting shaft, an inlet joint is arranged on the mandrel, the inlet joint can be ensured to supply media stably, a rotating sealing ring is arranged between the mandrel and the supporting shaft, stable rotation of the supporting shaft can be guaranteed, leakage is avoided, and the device has the characteristics of being compact in structure, small in occupied space, high in rotating speed, simple and convenient to maintain and the like.

Description

technical field [0001] The invention belongs to the field of machine tool components, and relates to a special coupling device for high-pressure oil pipes, cooling water pipes, oil-gas lubrication pipes and air pipes of a machine tool's swinging rotary shaft, and in particular to a multi-channel high-speed rotary joint device for swinging heads. Background technique [0002] The existing multi-channel rotating device used for oil pipes, cooling water pipes, oil-air lubrication pipes, and air pipes at the fixed end of the machine tool takes up a lot of space, and its large size makes it inconvenient to assemble, disassemble and maintain the multi-channel rotating device. Contents of the invention [0003] Aiming at the defects of the existing multi-channel rotating device which is inconvenient to assemble, disassemble and maintain due to its large size, the present invention aims to provide a multi-channel pipeline rotating connection device with a compact structure and conv...
