Abstract
The disclosure relates to a chain intelligent pre-tensioning and chain length detection method and device thereof. The device includes a rack, a work platform, a pre-tensioning power device, a measuring power device, a length measuring device and a console. The console receives the information of the length measuring device to adjust and control the pre-tensioning power device. The pre-tensioning and chain length measurement adopts a combination structure of an independently operated screw loading system as well as two sets of unique straight guide rails and four pallets mounted on the guide rail. The pre-tensioning force loading adopts the servo system and works with decelerator and precision grinding screw for loading. The measuring force loading adopts stepper motor and works with precision grinding screw for loading. The pretension and measurement adopt two tensile force sensors, so that chain pre-tensioning force and the chain length measuring force can be controlled accurately.
