Beschreibung
Zusammenfassung:	The invention provides a workppiece bearing device which comprises a base and a rotating plate. The base comprises a base plate and a first connecting plate arranged on the base plate, wherein a first shaft hole is formed in the first connecting plate, and a rotating platform is rotatably connected to the base through a first rotating shaft rotatably arranged in the first shaft hole. The workppiece bearing device further comprises an electromagnet and a switch, wherein the electromagnet is arranged on the rotating platform and located nearby the rotating shaft, the switch is used for electrical connection and disconnection of an external power supply and the electromagnet. When the switch is turned on to enable the external power supply and the electromagnet to be connected electrically, the electromagnet attracts the first connecting plate and then enables the rotating platform to be fixed. When the switch is turned off to enable the external power supply and the electromagnet to be disconnected electrically, the rotating platform can optionally rotate relative to the base plate under the effect of external force. The workppiece bearing device can drive parts to be assembled to rotate at a predetermined angle and can improve assembly efficiency when certain electronic devices are assembled.
