For some time working exhaustively in technical assistance, I decided to change my job and become a quality inspector in one of the construction and development companies for agricultural machinery and accessories; in such factory/company; the employees who play a brilliant role there in the construction of machines "faced" a problem regarding the alignment of pulleys; I developed on my own a simple and very efficient laser aligner; considering that the aligners we have in Brazil are expensive (such as the SKF brand).
Well, I would like to share this knowledgat I call T01; Thank you very much in advance!!!
Supplies
So that the construction of such equipment can occur; I indexed the photos of the components in Portuguese
Step 1: Presentation and Gift
Of course, the first step towards building our pulley aligner is in its original format, I will make the case files available to you in STL for printing on a 3D printer, I will also make a small exploded view of the aligner available, so that you can see from now on where each one fits.
Before we get into practice, it is necessary to fix the laser well and for this I used a superglue, such as tekbond or derived from acrylate-based glues (superbond), then I positioned the beater and (a small millimetered piece made on the 3D printer; in a can of uncrushed Nescal (of course...), in order to ensure that the glue dries I added a little salt, which in this case will act on the molecules of acrylates as a gap "filler" - thus transforming the combination of super glue + table salt into a somewhat resistant and extremely quick-drying composite!!!
Step 3: Some Details...
before actually "sticking" the magnets to the back of the aligner (laser head) with super glue, it will be necessary to sand this side; What I tell you is... first assemble the entire laser scope and then, after everything is fixed, sand with infinite movements (or in figure eights) to better roughen the printing lines; You can see the result in the photo I made available, clearly and extremely smooth and uniform... then... you can glue the 3 magnets into the holes very carefully and carefully!!!
Step 4: Time of Distress... of the Test, in Other Words...
The project was better than expected.... I can say that there were around 5 to 7mm of unevenness between pulleys; It is worth remembering that this tool is proof that the "aluminum rulers" are not as straight as expected in professional alignments; remember, misalignment can mean a form of torsion and if it is not previously observed, it can initiate a process of premature wear on the belts that go on the machine's pulley system; This is because, a lot of torque is carried out on such cultivation machine pulleys.
Step 5: Conclusion and Manual
Finally... I will be making the user manual available... however we have a problem... it is in my native language, so I ask you to understand my limitations and whatever questions you may have, I will be happy to answer you in the chat below!!!
