Assembling device for pump core combination part of fuel pump and method for assembling pump core combination part through assembling device

Abstract

An assembling device for a pump core combination part of a fuel pump comprises a base, a pump core positioning base, a pressing device and an air cylinder assembly. The air cylinder assembly is in circuit connection with an external control unit. A laser positioning monitoring device used for monitoring the assembling condition of the pump core combination part is arranged on one side of the base. A filter screen leak detecting device used for conducting purification quality redetection on a filter screen is arranged on one side of the pump core positioning base, and a blowing pipe and an adsorption pipe of the filter screen leak detecting device are connected with an external blowing and suction air source. Optoelectronic switches of the laser positioning monitoring device and the filter screen leak detecting device are in circuit connection with the external control unit. The pressing device is pushed by an air cylinder piston to conduct up-and-down motion to press the filter screen and a pressing plate onto a pump core. A method for assembling the pump core combination part through the assembling device comprises the steps of carrying out purification quality redetection on the filter screen, loading a lower support at the bottom of the pump core of the fuel pump and pressing the filter screen and the pressing plate at the same time. The assembling device is set with many links of detection monitoring, so the product quality can be ensured. The assembling method is easy and convenient to operate and high in working efficiency, and the labor intensity of operators can be greatly relieved.

Description

technical field [0001] The invention relates to an assembly device and an assembly method of automobile components, in particular to an assembly device for a fuel pump core assembly used in an automobile engine fuel supply system and a method for assembling the pump core assembly using the same. Background technique [0002] Automobile fuel pump pump element assembly refers to the assembly of the pump element and the filter screen of the fuel pump of the automobile engine fuel supply system. The traditional assembly is mainly by hand, and its process is as follows: 1) manually place the lower bracket in the fixture, 2) install the pressing sheet and filter screen, 3) install the pump core to obtain the pre-assembled assembly, and finally The assembly is pressed into a fixed position with a pneumatic device; the disadvantages are: [0003] 1. High labor intensity and low work efficiency; [0004] 2. The relative coaxiality of the moving parts (filter screen, pressing shee...

AI Technical Summary

Problems solved by technology

[0003] 1. High labor intensity and low work efficiency;

[0004] 2. The relative coaxiality of the moving parts (filter screen, pressing sheet) in the assembly is poor after combination;

[0005] 3. Pneumatic devices have no air pressure adjustment and metering, the air pressure is not guaranteed, and the blowing and suction re-inspection of the filter screen is not done during assembly, so it is impossible to prevent defective filter screens from being mixed into the assembly line and affect the quality of the pump core assembly
