Problems solved by technology

The gas distribution device used in the traditional technology adopts rubber sealing ring to prevent leakage. The existing gas distribution device has three disadvantages. One: the rubber sealing ring is easy to wear and has a short life (the life of the user buying it at will is shorter); : Rolling bearings need to be refueled frequently, and the rolling bearings will burn out if they are not properly maintained during high-speed operation; 3: The temperature rises and it is easy to damage other non-metallic parts

Abstract

The invention relates to a rotary gas distribution device for a pneumatic chuck, which comprises a jacket, a sliding bearing which is sleeved in the jacket in an interference manner and an inner shaft forming a sliding bearing pair with the sliding bearing, wherein the inner shaft comprises a rotating part sleeved in the sliding bearing and a connecting part extending out of the sliding shaft andbeing detachably fixedly connected with a lathe main spindle; a first gas inlet and a second gas inlet are arranged on the jacket; a first rotary gas cavity and a second rotary gas cavity which respectively correspond to the first gas inlet and the second gas inlet are arranged on the sliding bearing; and a first gas outlet communicated with the first rotary gas cavity through a first gas channeland a second gas outlet communicated with the second rotary gas cavity through a second gas channel are arranged on the connecting part of the inner shaft. The rotary gas distribution device has the advantages of no need of maintenance, no noise, small volume, light weight, capability of realizing high-speed operation, and the like. Due to the adoption of the rotary gas distribution device, the defects of the traditional rotary gas distribution device are eliminated and the manufacture cost is correspondingly lowered.

Description

technical field [0001] The invention relates to the technical field of machine tool fixtures, in particular to a rotary air distribution device for a pneumatic chuck. Background technique [0002] Pneumatic chuck is a common machine tool fixture. Each pneumatic chuck must use a rotary air distribution device during use. Its function is to prevent the two air supply pipes of the pneumatic chuck from being entangled during the rotation of the pneumatic chuck driven by the machine tool. together. The gas distribution device used in the traditional technology adopts rubber sealing ring to prevent leakage. The existing gas distribution device has three disadvantages. One: the rubber sealing ring is easy to wear and has a short life (the life of the user buying it at will is shorter); : Rolling bearings need to be refueled frequently, and the rolling bearings will burn out if they are not properly cared for during high-speed operation; 3: The temperature rises and easily damages ...
