The utility model discloses the theory of operation: when the electrode blank clamping device is used, the electrode blank is placed in the fixing clamp, the electrode blank is clamped through the fixing clamp, then the motor is started, the worm is driven to rotate when the motor operates, the worm is driven to rotate when the worm rotates, the fixing clamp is driven to move downwards along the sliding rail when the worm rotates, the electrode blank is driven to move downwards when the fixing clamp moves downwards, the motor stops operating after the electrode blank moves to a proper position, and the brake ring starts to clamp and fix the output shaft of the motor when the motor is closed due to the fact that a switch of the motor is in electric signal connection with the brake ring, and the electrode blank is prevented from continuing to rotate under the action of inertia.

The utility model has the advantages that: according to the scheme, the brake ring is connected with the switch electric signal of the motor, so that the brake ring is in a non-running state when the motor runs, the brake ring is opened when the motor stops running, the motor is limited to continue rotating, and the beneficial effect of accurate control that the fixing clamp can stop moving when the motor stops running is achieved.

Further, the motor is a servo motor. The purpose is to improve the control precision through a servo motor.

Furthermore, a brake pad is arranged on one side of the brake ring, which is contacted with the output shaft of the motor. The purpose is to increase the braking performance by the brake pad.

Furthermore, the brake pad is detachably connected with the brake ring. The purpose is to facilitate the replacement of the brake pad.

Furthermore, a controller is arranged on the main support and is in electric signal connection with the servo motor and the brake ring. The controller is used for controlling the servo motor and the brake ring, and the controller receives a signal when the servo motor stops running so as to immediately control the brake ring to start.

Further, the controller is a PLC controller. The purpose is that the PLC controller is simple and reliable in control.

Further, the bottom fixedly connected with of bracing piece is used for the electronic spacing clamp of centre gripping slide rail, spacing clamp and slide rail sliding connection, spacing clamp and controller signal of telecommunication connection. The purpose is, when servo motor stopped to move, through the electronic spacing clamp of controller control centre gripping slide rail, when increasing the stability of fixation clamp, further improve the accuracy of control.
