Fuel pump production line

Abstract

A fuel pump production line comprises a precision magnetic shoe assembly machine, a precision oil outlet plate component assembly machine, a precision pump body component assembly machine and a precision pump core comprehensive performance detector. The precision magnetic shoe assembly machine presses a carbon brush holder and a magnetic shoe into an iron shell by cooperation of a carbon brush holder positioning mould, an iron shell positioning mould and a magnetic shoe positioning mould. The precision oil outlet plate component assembly machine realizes press fit of a copper bush and an oil outlet plate by cooperation of a copper bush positioning device and an oil outlet plate positioning device, automatically grabs and puts a rotor into the iron shell by the aid of a grabbing device and realizes press fit of the oil outlet plate and the rotor in the iron shell by the aid of the iron shell positioning device and the oil outlet plate positioning device. The precision pump body component assembly machine supplies power to a pump body by the aid of a probe in a pressure cover to test whether the pump body is capable of rotating or not, tightly presses a head cover and seals edges of the iron shell of the pump body to complete pump body assembly and preliminary testing. The precision pump core comprehensive performance detector automatically detects an assembled pump core. Therefore, automatic production of a production line is realized.

Description

technical field [0001] The invention relates to automatic assembly and testing equipment, in particular to a fuel pump production line. Background technique [0002] The fuel pump structure is composed of iron shell, carbon brush holder, magnetic tile, rotor, oil outlet pan and other components. The assembly of the fuel pump can be divided into several steps: the assembly of the carbon brush holder and the magnetic tile, the assembly of the oil outlet pan, the assembly of the pump body, and the test of the pump body. At present, domestic automotive fuel pump manufacturers basically use manual assembly for each assembly process of the fuel pump. The assembly mode is manual assembly on the workbench, which brings many disadvantages: manual assembly makes the assembly accuracy of the product Poor, the accuracy of the product cannot be guaranteed; more manual participation, resulting in potential safety hazards in the production line; low production capacity, affecting the prod...
