A method for detecting the position of a built-in component in an automobile fuel tank

Abstract

The invention provides a method for detecting the position of a built-in member of an automobile fuel tank, and the method comprises the following steps: 1, calibrating a detection position of a to-be-detected built-in member of the automobile fuel tank on a horizontal projection surface; 2, making a position detecting device according to the position on the calibration projection surface, whereina mold is provided with different detecting mechanisms according to the detection contents at different detection positions; 3, making a destruction guide device with a drill mold according to the position on the calibration projection surface, wherein the size of a drill hole is matched with the detecting mechanisms for detecting the built-in member at the position; 4, making a positioning device according to the shape of the to-be-detected fuel tank; 5, firmly fixing the fuel tank on the fixing device, fixing the drill mold at the upper end of the fuel tank, and drilling an upper cover of the fuel tank through a drilling tool; 6, removing the destruction guide device, fixing the position detecting device at the upper end of the fuel tank, and adjusting the heights of the detecting mechanism to detect the built-in member of the fuel tank.

Description

technical field [0001] The invention relates to the technical field of fuel tank detection methods, in particular to a detection method for the position of an automotive fuel tank inner part. Background technique [0002] With the rapid development of the domestic economy, there are more and more cars in the society, and there are more and more requirements for car maintenance and repair. As an important part of the car, the fuel tank of a car has always been concerned about its safety performance. The fuel tank of a car is not only a tank for storing fuel, but also has many built-in parts inside, such as sensors for detecting fuel temperature, detecting fuel Sensors for liquid level, sensors for detecting oil leakage, etc., are distributed in various places in the fuel tank of automobiles, and their position detection is particularly important. [0003] For example, Chinese patent CN104833404A discloses a fuel level detection device, an automobile, a fuel tank and a fuel l...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problems in the prior art that the detection needs to destroy the fuel tank and cannot detect multiple detection points at the same time, the present invention provides a detection method for the position of the internal parts of the automobile fuel tank
