VERFAHREN ZUM BESTIMMEN DER QUALITAET EINER REIBUNGSSCHWEISSVERBINDUNG SOWIE REIBUNGSSCHWEISSGERAET

摘要

An integral braking means is for braking a livetool or spindle of a spinwelding machine, and the quality of a spinweld bond produced on a single or multiple spindle production spinwelder can be determined. There are also arrangements for alarming and/or ejecting products containing defective welds. The braking consists of a self-adjusting cam-actuated, spring loaded brake (207, 210, 214) adapted to bear against a wear resistant braking surface (204). A detector is used to determine the condition of a tool or spindle (i.e. if it is still live i.e. rotating when it should be at rest) and a timing means actuates an indicator when a live tool is detected. There is also means to detect a spinweld station with an actuated indicator and to eject the product thereon and a device for automatically shutting down a spinwelder which produces an excess of defective products.
