Cleaning machine for gas spring pressure pipe

Abstract

The invention relates to the technical field of gas spring manufacturing, in particular to a cleaning machine for a gas spring pressure pipe. The cleaning machine comprises a rack and a hydraulic cylinder arranged on the rack, and the extending end of the hydraulic cylinder faces downwards. A motor is arranged at the extending end of the hydraulic cylinder. A rotary plate is fixedly connected to a main shaft of the motor. A rotary shaft is arranged on the rotary plate. A T-shaped protrusion is arranged at the upper end of the rotary shaft. A bristle brush assembly is arranged at the lower end of the rotary shaft. A T-shaped groove matched with the T-shaped protrusion is formed in the lower surface of the rotary plate. A spring is arranged between the T-shaped groove and the T-shaped protrusion. A fixing base is arranged under the bristle brush assembly. A positioning hole matched with the pressure pipe is formed in the fixing base. The positioning hole and the rotary plate are coaxial. The bristle brush assembly is placed in the positioning hole by transversely moving the rotary shaft, the spring is in a compressed state at the moment, and one side of the bristle brush assembly is tightly attached to the inner wall of the pressure pipe under the action of the spring so that the inner wall of the pressure pipe can be better cleaned by the bristle brush assembly. The cleaning effect on the pressure pipe is improved, and the cleaning efficiency is high.

Description

Technical field [0001] The invention relates to the technical field of gas spring manufacturing, in particular to a cleaning machine for gas spring pressure tubes. Background technique [0002] Gas spring is a component that requires high precision and cleanliness. As the main body of the gas spring component, the pressure tube requires a roughness of Ra0.2 on the outer and inner walls. Because the core rod lubricating grease sticks to the inner wall during the cold drawing of the tube material In addition, in machining and cutting, a lot of iron filings will stick into the inner wall of the hole, so cleaning the inner wall of the pressure tube becomes a necessary process before the next process. The conventional cleaning of the pressure tube is manual. One hand puts the pressure tube into the kerosene, and the other hand holds the brush corresponding to the inner diameter and length of the pressure tube to reciprocate in the hole. The tube continuously rotates to clean the inne...
