Device for polishing surface of spherical joint of high-pressure oil pipe

Abstract

The invention relates to a device for polishing a surface of a spherical joint of a high-pressure oil pipe. The device comprises a workbench, a polishing mechanism and a part moving mechanism arranged on the workbench, a part supporting mechanism arranged on the part moving mechanism and a part compressing mechanism which is arranged on the part moving mechanism and matched with the part supporting mechanism. The high-pressure oil pipe with one end provided with the spherical joint is arranged between the part supporting mechanism and the part compressing mechanism, the part moving mechanism is moved to a preset position, and the polishing mechanism polishes the surface of the spherical joint. Compared with the prior art, the device has the beneficial effects that the mechanical manner is adopted to automatic polishing, the problems that the polishing quality is instable and the polishing effect consistency is poor and other problems caused by manual polishing are avoided, the product quality is improved, operation is easy and convenient, the polishing efficiency of the spherical joint can be greatly improved, and volume production is achieved conveniently.

Description

technical field [0001] The invention belongs to the technical field of high-pressure oil pipes, and relates to a device for polishing the surface of spherical joints of high-pressure oil pipes. Background technique [0002] The high-pressure oil pipe is a part of the high-pressure oil circuit, which can withstand a certain oil pressure and has a certain fatigue strength to ensure the sealing of the pipeline. The high-pressure oil pipe for vehicles is mainly used in high-pressure injection diesel engines and high-pressure injection direct-injection gasoline engines. Withstands the oil pressure required during engine operation. The high-pressure oil pipe is connected to the high-pressure oil circuit through a joint, and the common joint is a ball joint. At present, the surface polishing of the ball joint of the high-pressure oil pipe is mainly carried out manually. Not only the polishing efficiency is low, but it cannot adapt to mass production, which limits the further impro...

AI Technical Summary

Problems solved by technology

At present, the surface polishing of the ball joint of the high-pressure oil pipe is mainly carried out manually. Not only the polishing efficiency is low, but it cannot adapt to mass production, which limits the further improvement of production efficiency. The effect is consistent, and the polishing quality is unstable, which affects the normal use of the product
