Part of the demand for indexer manufacturers in the choice of indexer due to the lack of consideration of the speed of the problem, resulting in automation systems in high-speed operation of the entire turntable jitter, but also what we call, the indexer running instability, this situation, very easy to cause the entire automation system of the decline in accuracy, and even affect the indexing positioning offset.
Indexer speed from the current point of view, there is no defined standard, we are reviewing, is in the actual application, very easy to occur in the jittery situation, the speed of the indexer can normally reach 600RPM, that is, every second into the force axis rotation speed can reach 10 turns, there are higher, the speed can be up to 800RPM, in this case, for the indexer's mechanical properties In this case, it is a great test for the mechanical performance of the indexer. Therefore, we regard the situation where the entry force shaft rotates below 1 second as the case of high speed operation of the indexer.
Indexer in the case of high-speed operation, the indexer into the force cam and out of the force turret from the movement to stop the switching process, or from the stop to the athlete's start-up process, will produce a large inertial impact, and the cam surface of the switching point, and the out of the force turret of the mechanical matching movement is the main reason for jitter of the indexer, the highest realm of mechanical movement is not by transmission, we are accustomed to say that indexer The highest level of mechanical movement is not by transmission, we are accustomed to say that the indexer of the force into the cam pulling the force out of the turret movement, and the actual mechanical movement should be a harmonious match between the components, which needs to include the indexer cam and the force out of the turret at the beginning of the design should be from the beginning of the program to the processing, taking into account the arc cam and the rollers between the point, line, surface of the harmony with the match. From the point of view of mechanical movement, greater reduction of friction due to wear and tear between the machinery.
In the process of running the indexer, the contact between the arc surface and the arc surface is unavoidable, so the use of materials and processing accuracy will have a greater impact on the articulation and friction between the components, the hardness of the material and the smoothness of the cam surface machining is the cause of jitter in the rotation of the indexer's components. This is why we have always emphasized the importance of the use of indexing materials and the use of machining equipment for the quality of the indexer itself. It is also worth mentioning that measuring equipment is indispensable.
