Abstract
The utility model discloses an on-line controlling electrode filament tensioning device, which is characterized by comprising a closed electrode filament movement path formed by a filament storage canister and a plurality of metal guide wheels. The on-line controlling electrode filament tensioning device also comprises a sliding plate and the sliding plate parallel to the movement direction of an electrode filament is used for fixing the filament storage canister mechanism. The sliding plate is driven to move linearly by a servo motor and then the filament storage canister mechanism is driven to move by the sliding plate. A tension sensor used for adjusting the tension force of an electrode filament is arranged in the movement path of the electrode filament so as to detect the tension status of the electrode filament and send out a corresponding electrical signal. Due to the adoption of the tensioning device, an electrode filament operated through an electric spark filament cutting machine is maintained at a constant tension state in a movement and the extension of the electrode filament caused by an imposed external force applied on the electrode filament is prevented. Meanwhile, the invalid loss of the electrode filament is reduced. The stability, the machining efficiency and the discharge machining quality of the discharge machining are also improved.
