Abstract

The invention relates to a device used for assembling a sealing joint of a high-pressure oil rail. The device comprises a workbench, a slide rail arranged on the workbench, a sealing joint screw-up mechanism which is arranged on the slide rail in a sliding mode, and a high-pressure oil rail clamping mechanism which is adaptive to the sealing joint screw-up mechanism, wherein the high-pressure oil rail with a sealing joint at one end is arranged in the high-pressure oil rail clamping mechanism; the position, on the slide rail, of the sealing joint screw-up mechanism is regulated, and then the sealing joint is screwed up and assembled at one end of the high-pressure oil rail through the sealing joint screw-up mechanism. Compared with the prior art, the device is simple to operate, greatly improves assembly efficiency, guarantees consistency of screw-up degrees of different batches of products, and is good in reliability.

Description

technical field [0001] The invention belongs to the technical field of high-pressure oil rails, and relates to a device for assembling sealed joints of high-pressure oil rails. Background technique [0002] The function of the high-pressure fuel rail is to store fuel, and at the same time suppress the pressure fluctuations caused by the high-pressure pump fuel supply and the fuel injection of the fuel injector, so as to ensure the stability of the system pressure. During the processing of the high-pressure oil rail, a sealing joint needs to be screwed into one end of the high-pressure oil rail to ensure the sealing performance of the high-pressure oil rail during use. At present, the assembly of the sealing joint of the high-pressure oil rail is carried out manually, and the assembly is carried out by using a torque wrench. This method is not only inefficient and unable to adapt to mass production, but also due to the manual operation, it is difficult to ensure that the tig...
