Processing and manufacturing of lamp inspection fixture
Firstly, the back surface and the limit groove of module 2 are processed, and the two module groups are matched by the limit groove and the limit boss and glued. In order to eliminate the cumulative error, in module 1
Module 1 processing
For the qualified blank of bottom mounting module 1, the contour of module 1 and the positioning boss on the top surface are finished by the machining center to ensure the qualified positioning size.
Module 2 and module 3 processing
Firstly, the back surface and limit groove of module 2 are processed, and the two modules are matched by the limit groove and the limit boss and glued together. In order to eliminate the accumulated error, the module 2 is processed on the processing benchmark of the module 1, and then the insert and positioning block inside the module 2 are installed to the theoretical position on the CMM
The processing of module 3 is the same as that of module 2, and the cooperation with module 2 is realized in the same way
Module 4 processing
After assembling all the inserts and stop blocks of the first three modules, the automobile inspection tool processes module 4 according to the processing process of module 3, and realizes the cooperation with the first three modules in the same way, and processes the top surface of module 4 on the basis of the inspection tool processing benchmark to complete the processing of all modules. By combining with the material properties and reasonably changing the process, the problems of the inspection tool can not be processed because of the narrow area and the lack of installation and operation space are solved on the conventional equipment. The processing and assembly of the inspection tool are successfully completed, and the accuracy of the inspection tool is ensured.
Perfect inspection tools
According to the requirements of the project, the automobile inspection tools after processing and assembling are sprayed with the corresponding project color number, pasted with the reference plate and installed with the reference cover. The inspection tools after detailed treatment are complete and concise in appearance, without redundant holes and grooves.
