ELECTRICAL CLAMPING APPARATUS HAVING MANUAL RELEASE CLUTCH WITH IMPROVED SAFETY AND SPACE EFFICIENCY AND CONTROL METHOD USING SAME

摘要

The present invention relates to an electrical clamping apparatus for fixing the position of a vehicle component and, to a clamping apparatus for fixing the position of a component in a movable production line comprising: a drive motor; a warm shaft which rotates by the drive motor; a warm wheel which rotates while being engaged with the warm shaft; a rotating shaft which rotates while being engaged with the warm wheel; a pressure member for fixing the position of a component which is under production in a production line since the pressure member is moved by being combined to the end of the rotating shaft and interlocked with the rotating shaft; and a control part for rotating the drive motor until the pressure member reaches a fixing position where the pressure member fixes the position of the component in the production line from an opening location where a moving path of the component is opened by pressurizing the component. The position of a vehicle component such as a vehicle chassis, etc. which moves along a production line by using the drive motor is fixed at a position of processes such as welding, etc., wherein the drive motor occupies small space, and has a rapid response speed in comparison with a pneumatic clamping apparatus. Therefore, an electrical clamping apparatus for fixing a position is capable of preventing safety accident while efficiently, correctly, and rapidly implementing a production process of a vehicle.
