The optical axis needs to be pinpointed in the clapboard and eccentrically operated between the upper and lower plates.

Hollow axis is also a kind of linear optical axis, it is used in a variety of occasions, so the installation of the relevant natural to know. For example, what should we do to install the hollow shaft and the drive plate now? Optic axis
Starting with the processing of the guide post, it is generally made of 20# steel, roughed by lathe, heat treatment, lapping holes and cylindrical grinding. In order to further improve the dimensional accuracy and surface roughness of the guide post, the allowance can be reserved after cylindrical grinding and grinded again.
When grinding with a disc grinder, the guide post needs to be clamped in the baffle and eccentrically operated between the upper and lower grinding plates, so that the motion direction of the guide post will change periodically, so that the grinding agent is evenly distributed and the surface of the guide post will form a crisscross grinding trace. It seems that this grinding method is not only high productivity, grinding tool wear is more even hook, suitable for large-scale production of guide post.
In order to realize the joint installation of hollow shaft and drive disc, the necessary parts must be prepared first. In addition to the hollow shaft and drive disc, the fastening bolts must not be missing. Then the hollow shaft shaft body is connected with the transmission disc by the end gear disc, which is composed of the left end gear disc and the right end gear disc meshing.
