The invention relates to a hydraulic jack cylinder barrel inner wall polishing device. The hydraulic jack cylinder barrel inner wall polishing device comprises a machine tool, at least two supporting devices and a polishing device, wherein the machine tool comprises a machine base; one end of the machine base is arranged on a first chuck, and the other end is slidably connected with a second chuck; and the at least three supporting devices are connected to the machine base in a sliding mode and are located between the first chuck and the second chuck. The polishing device is rotationally connected into one supporting device, one end of the polishing device is connected with the second chuck, the other end of the polishing device penetrates into the cylinder barrel, the cylinder barrel is rotationally connected into the remaining supporting devices, and the end of the cylinder barrel is connected with the first chuck. The first chuck and the second chuck are both suitable for rotating motion and can drive the cylinder barrel and the polishing device to rotate at the differential speed, and the polishing device grinds the inner wall of the cylinder barrel. The hydraulic jack cylinder barrel inner wall polishing device is modified based on an existing machine tool, the structure is simple, and the modification cost is low.
Description
technical field [0001] The invention relates to the technical field of surface treatment, in particular to a polishing device for the inner wall of a cylinder barrel of a hydraulic jack. Background technique [0002] As the main component of power equipment, hydraulic jacks generally use hydraulic oil, emulsion or water medium as the power transmission medium, and withstand hundreds of atmospheric pressures or even greater, so the requirements for the sealing performance of the jack are very high. In addition, a good inner wall finish affects the service life of the seal, and the inner wall of the jack usually requires inner wall anti-corrosion treatment, including coating, oxidation, phosphating, spraying and other treatments, which will change the surface finish of the inner wall of the jack cylinder, so It is necessary to carry out surface treatment on the inner wall of the jack cylinder. Generally speaking, the thickness of the protective layer of most surface treatments...
