Installation tool for filtering net of oil pump

Abstract

The invention discloses an installation tool for a filtering net of an oil pump. The installation tool comprises a bottom plate (3), a positioning plate (4), a pressing device, a filtering net press mounting device and a pressure release valve installation device. The positioning plate (4) is vertically connected to the bottom plate (3) which is horizontally arranged. The filtering net press mounting device is connected to the bottom plate (3) through a support assembly, and a pressing head plate (16) in the filtering net press mounting device is located over an oil inlet of a pump body. The pressure release valve installation device is connected to the bottom plate (3), and the movement direction of the movable end of the pressure release valve installation device is the horizontal direction consistent with the direction of the axis of an installation opening of the pump body. After the above structure is adopted, the pump body of the oil pump does not need to be secondarily clamped, and therefore the assembling efficiency is greatly improved; and in addition, the benchmark does not need to be found again during assembling, and therefore the assembling quality of a product is better ensured.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a tool for installing oil pump filter screens. Background technique [0002] When the automobile engine is working, each moving part acts on another part with a certain force, and high-speed relative motion occurs. With relative motion, friction will inevitably occur on the surface of the parts, thereby accelerating wear. Therefore, in order to reduce wear and tear, reduce friction resistance and prolong service life, there must be lubrication system parts on the engine. The main components of the lubrication system are various equipment such as an oil pump. The function of the oil pump is to increase the oil to a certain pressure and then forcefully send it to the moving surface of each part of the engine. It generally includes a pump cover and a pump body. It is connected with the pump body by screws, and the pump body is equipped with an inner rotor, an outer rotor, a spring, ...

AI Technical Summary

Problems solved by technology

[0004] 1) Since the oil pump needs to be fixed to operate whether it is the installation of the filter screen or the installation of the pressure relief valve, when the oil pump body is changed from one station to another, it needs to be installed in the previous station. One station is disassembled and the benchmark and clamping are re-adjusted at the next station, which greatly reduces the assembly efficiency;

[0005] 2) When the pump body of the oil pump is removed from the previous station and replaced to the next station, it is necessary to re-locate the pump body to ensure that the assembly accuracy at this station can be more accurate. However, even if the repositioning When looking for the benchmark, there will also be inconsistencies with the benchmark of the previous station. Therefore, assembly deviations will also occur, which will affect the assembly quality of the final product.
