Looking for a deeper explanation on the pin-slot alignment ... - Reddit
2020年8月18日 · Using the pin and slot, you can put a really tight tolerance on the pin and it then put it in a press fit on one side, and a tight slip fit on the other. This will position it well, and the slot will make sure the parts fit together no matter what.
Reasonble position tolerance for 1.5mm dowel pins?
2023年1月17日 · For the 1,5x5 mm, m6 tolerance pins (spaced 20 mm apart) which would fit my application, H7 tolerance holes are suggested for a "typical" transition fit. However, I failed to find any information on the required positional tolerance of the holes to ensure the parts can be assembled properly.
To achieve optimal alignment when using Coiled Pins, two primary design elements must be adhered to: 1) The hole diameters in the host and mating component must be correctly sized to achieve the desired interference and accuracy of alignment. 2) The engagement length of the Coiled Pin in the component providing primary retention must be
Alignment Features - Hole/Hole vs Hole/Slot - Engineers Edge
Also, if the alignment pins are longgggg.. one may have to rock the parts to get the parts to mate properly, Hole - slot is preferred for tight fits as the pin-hole positions or locates and the pin-slot stops the rotation and allows for easier installation due to the clearance along the slot length.
