Multistage expansion pressure oil pipe

Abstract

The invention relates to a multistage expansion pressure oil pipe. The multistage expansion pressure oil pipe comprises a large joint pipe, a large joint base, a large joint sleeve, a middle joint pipe, a large joint flange, a middle joint flange, a middle joint sleeve, a small joint pipe and a small joint sleeve, wherein the large joint base is arranged at the lower end of the large joint pipe, the large joint base is provided with a circulating hole communicated with the large joint pipe, the large joint sleeve is arranged at the upper end of the large joint pipe, the middle joint pipe is arranged in the large joint pipe through the large joint sleeve, the large joint flange is further arranged at the upper end of the large joint sleeve, the middle joint sleeve is arranged at the upper end of the middle joint pipe, the small joint pipe is arranged in the middle joint pipe through the middle joint sleeve, the middle joint flange is further arranged at the upper end of the middle joint sleeve, and the small joint sleeve is arranged at the upper end of the small joint pipe. Due to the scheme, the multistage expansion pressure oil pipe is simple in structure, when equipment connected with the small joint pipe moves conveniently, pressure oil can be normally transported, the using requirement is met, and high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of oil pipes, in particular to a multi-stage telescopic pressure oil pipe. Background technique [0002] A CNC machine tool is an automatic machine tool equipped with a program control system, which can logically process programs with control codes or other symbolic instructions and decode them, so that the machine tool can move and process parts. Existing CNC machine tools are generally equipped with pressure oil pipes for washing and cooling the workpiece. When in use, one end of the pressure oil pipe is connected to the device where the pressure oil moves with the actuator, and the other end is connected to the oil inlet. The existing pressure oil pipe is a common hose structure. When the equipment moving with the actuator is moving, the hose cannot transmit the pressure oil, so that the workpiece cannot be washed and cooled well. Contents of the invention [0003] The object of the present invention ...
