Therefore, the invention aims to provide a method for improving the measurement accuracy of an outer plate of an automobile engine cover, and aims to improve the measurement accuracy of the outer plate of the automobile engine cover.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the method for improving the measurement accuracy of the outer plate of the automobile engine cover comprises the following steps:
s1, punching a positioning hole on the outer plate of the engine cover in a punching process;
s2, mounting the first positioning device and the second positioning device on the checking fixture;
s3, in the detecting step, the hood outer panel is positioned by the first positioning device and the second positioning device, and the first positioning device and the second positioning device are inserted into one positioning hole in the hood outer panel, respectively.
The first positioning device comprises a first positioning seat arranged on the checking fixture and a first positioning pin arranged on the first positioning seat.
The first positioning pin is vertically arranged.
The second positioning device comprises a second positioning seat arranged on the checking fixture and a second positioning pin arranged on the second positioning seat.
The second locating pin is arranged vertically.
The first positioning device and the second positioning device are positioned on the same straight line parallel to the length direction of the outer plate of the engine cover.
The method for improving the measurement precision of the outer plate of the automobile engine cover can improve the measurement precision and the measurement efficiency of the outer plate of the engine cover and ensure the consistency of measurement data.

Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a purpose of helping those skilled in the art to more fully, accurately and deeply understand the concept and technical solution of the present invention and to facilitate its implementation.
It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in structure and/or function, nor represent a sequential execution order, but merely for convenience of description.
As shown in fig. 1 to 4, the present invention provides a method for improving the measurement accuracy of an outer plate of an automobile engine cover, comprising the following steps:
s1, punching a positioning hole on the outer plate of the engine cover in a punching process;
s2, mounting the first positioning device and the second positioning device on the detection tool 3;
s3, in the detecting step, the hood outer panel is positioned by the first positioning device and the second positioning device, and the first positioning device and the second positioning device are inserted into the positioning holes of the hood outer panel, respectively.
Specifically, as shown in fig. 1, in step S1, the sheet metal member is pressed by a press die to form the hood outer panel. Stamping die includes die holder 1 and sets up drift 2 on die holder 1, is carrying out the in-process of punching press to the sheet metal component, is punched a hole to the sheet metal component by drift 2, punches out the locating hole on the final bonnet planking that forms, and the locating hole sets up two, and two locating holes are in on the same straight line that parallels with the length direction of bonnet planking, according to stamping workpiece molding and detection demand decision locating hole position.
As shown in fig. 2 and 4, the first positioning device includes a first positioning seat 4 disposed on the inspection tool 3 and a first positioning pin 5 disposed on the first positioning seat 4, the first positioning seat 4 is vertically disposed, and the first positioning pin 5 is vertically disposed. The first locating pin 5 is installed at the upper end of the first locating seat 4 through a bolt, and the first locating pin 5 is prevented from moving. The second positioning device comprises a second positioning seat 6 arranged on the checking fixture 3 and a second positioning pin 7 arranged on the second positioning seat 6, the second positioning seat 6 is vertically arranged, and the second positioning pin 7 is vertically arranged. The second positioning pin 7 is mounted at the upper end of the second positioning seat 6 through a bolt, so that the second positioning pin 7 is prevented from moving.
As shown in fig. 2, the first positioning device and the second positioning device are on the same straight line parallel to the longitudinal direction of the hood outer panel.
In step S3, after the bonnet outer panel is placed on the check tool 3, the first positioning pin 5 and the second positioning pin 7 are inserted into one positioning hole on the bonnet outer panel, the bonnet outer panel is positioned by using the first positioning pin 5 and the second positioning pin 7 as positioning references, and the bonnet outer panel is measured after the positioning is completed.
The method for improving the measurement accuracy of the outer plate of the automobile engine cover has the following advantages:
1. the measuring time for detecting the outer plate of the engine cover by production line inspectors is saved;
2. the measurement precision of the outer plate of the engine cover is improved, and measurement guarantee is provided for the quality precision of the outer plate of the engine cover;
3. the operation is convenient, simple and easy to understand.
The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
