Abstract

The invention discloses a copper bush press-mounting machine, which comprises a top plate and a bottom plate, wherein the top plate is connected with the bottom plate to form a whole through an upright post; the inner side of the bottom plate is provided with a workpiece conveying device, the workpiece conveying device is in drive connection with a first hydraulic cylinder, one end of the outer side of the bottom plate is provided with a workpiece pre-positioning device, and the workpiece pre-positioning device is in drive connection with a second hydraulic cylinder; a workpiece process hole positioning mechanism and a workpiece bottom surface positioning block are arranged above the bottom plate, and the workpiece process hole positioning mechanism is in drive connection with a third hydraulic cylinder; a special hydraulic cylinder is arranged on the top plate, and the special hydraulic cylinder is provided with piston rods of double-rod structure and formed by sleeving the large piston rod on the small piston rod; and a press-sleeving mechanism is connected on the large piston rod of the special hydraulic cylinder, and a press rod mechanism is connected on the small piston rod of the special hydraulic cylinder. The copper bush press-mounting machine is convenient to operate, and has the advantages of reliable press-mounting quality, high production efficiency and the like.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a copper sleeve press-fitting machine for multiple fuel injectors in cylinder heads of multi-cylinder diesel engines in the engine industry. Background technique [0002] In the structure of the cylinder head of a diesel engine, there is a fuel injector installed in the copper sleeve of the fuel injector, and the copper sleeve of the fuel injector is embedded in the injector hole through the water cavity in the cylinder head. In order to prevent the cooling water from leaking out of the cylinder head or into the combustion chamber, the lower end of the copper sleeve of the fuel injector is an interference fit with the cylinder head, and the outer circle of the upper end and the cylinder head are sealed by a sealing ring. When the diesel engine is working, the cooling water in the cylinder head flows into the cylinder head, bypasses the copper sleeve of the injector and enters the water outl...
