Embodiment Construction

[0022] The technical solutions of the present invention are described in detail below through the examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, but cannot be interpreted as limitations to the technical solutions of the present invention.

[0023] At present, for the sake of integration, the engine oil pump is integrated on the front end cover of the engine, and many rotor oil pumps adopt the crankshaft direct drive scheme. Many of these oil pumps are faced with the need to position the oil pump rotor at the same time during assembly. And the problem of positioning the hole in the front cover.

[0024] The rotor of the oil pump can rotate freely in the pump chamber, so before the oil pump is assembled, the angle of the hexagonal hole where the center of the rotor matches the crankshaft is random, such as Figure 1 to Figure 4 As shown, if there is no frock provided by the pres...

Abstract

The invention relates to an oil pump assembly tool which comprises a tool base body. A plurality of tool guide legs are arranged on the tool base body, each tool guide leg corresponds to a corner angle of a rotor driver, and the inner side face of each tool guide leg forms the cross section shape of the rotor driver in a surrounding mode. According to the technical scheme, in consideration of integration, oil pumps of an engine are all integrated on a front end cover plate of the engine, a crankshaft direct drive scheme is adopted in many rotor type oil pumps, and the oil pumps face the problem that oil pump rotors and front end cover plate positioning sleeve holes need to be positioned at the same time in the assembling process. According to the technical scheme, through the unique structural design, the oil pump can be assembled more smoothly while the oil pump is ensured to be positioned accurately.

Description

technical field [0001] The invention relates to the technical field of engine oil pump auxiliary device tools, in particular to an oil pump assembly tool. Background technique [0002] The oil pump is the core of the lubrication system, and assembly reliability is very important. At the same time, with the compactness of the engine structure and the development of integration, many oil pumps are integrated on the front end cover of the engine, and the engine integrated on the front end cover When assembling the oil pump, since the positioning of the front cover plate and the oil pump must be taken into account at the same time, the assembly efficiency and difficulty of assembly will increase, which will affect the smoothness of the production rhythm of the production line and increase the assembly time and cost. Contents of the invention [0003] The purpose of the present invention is to provide an oil pump assembly tool to solve the problem that many oil pumps face the n...
