Automatic screw coupling device

摘要

The automatic screw coupling has the screw spindle (1) coupled by a thread with two or more starts to an outer cylinder (5) open in funnel form on one side. Inside, there is a displacement device consisting of one or two linear motors (8,9). The displacement device moves the rotary motor (10) with the screw spindle. The outer cylinder is closed on the other side by a cap (11), which has spring holders (12-14) on the outside. A magnetic brake may also be fitted.
