Shaft spacing is an important basis for deciding whether to adopt a multi-axis solution.Due to some products, there are many screws that need to be locked at once, and some products have a too small distance between the screw holes (electrical components), so that the batch nozzle cannot be positioned. To be conservative, the design condition of the speed-speed ordinary multi-axis automatic screwing machine positioning axis spacing is greater than 20mm. That is to say, the distance between the screw holes of the product should be greater than 10mm. In order to ensure that the two adjacent batch nozzles can be maintained at more than 20mm, ensure that accurate locating.
