Abstract

The invention relates to an assembly tooling of a piston cooling nozzle assembly. The assembly tooling comprises a connecting rod, wherein the upper end part of the connecting rod is a torque connector; the lower end part of the connecting rod is a hexagonal prism; a hollow sleeve of which the lower end face is of an open structure is arranged on the hexagonal prism in a sleeving manner; a baffle plate is arranged inside the hollow sleeve; central holes are formed in an upper end panel of the hollow sleeve and the baffle plate; a connecting rod pressing block used for preventing the hexagonal prism from falling off the hollow sleeve is arranged at the upper end part of the hexagonal prism; a buffer reset spring which is positioned inside the hollow sleeve is limited between the connecting rod pressing block and the baffle plate; the baffle plate of the hollow sleeve and the side wall below the baffle plate define an accommodating space of the piston cooling nozzle assembly; a limiting bayonet used for limiting up-and-down motion of an oil injection tube of the piston cooling nozzle assembly is formed in the side wall of the accommodating space; and the opening of the limiting bayonet is in the lower end face of the hollow sleeve. The invention further relates to an assembly method of the piston cooling nozzle assembly. According to the assembly tooling, the problems that a conventional tooling cannot achieve one-time assembly and the size of the tooling is relatively large are solved.

Description

technical field [0001] The invention relates to the technical field of automobile engine assembly, in particular to an assembly tool and an assembly method for a piston cooling nozzle assembly. Background technique [0002] With the application of direct injection and supercharging technology in the engine cylinder, the requirements for the ability of engine parts, especially pistons to withstand thermal loads, continue to increase. Piston cooling nozzles are arranged on the engine to force the piston (especially the head) to cool. The piston cooling nozzles are generally arranged on the main oil passage inside the cylinder body. Generally, the metal pipe fittings of the piston cooling nozzles are manually assembled, and then the valve core bolts are assembled. Due to the narrow space of some engines, it is not easy to operate the assembly of the piston cooling nozzle assembly. Only by adjusting the production process, the piston cooling nozzle assembly can be assembled firs...
