Automatic fixed-length cutting device of profile clamping groove for cable laying and control method

The invention discloses an automatic fixed-length cutting device of a profile clamping groove for cable laying and a control method, a baffle assembly is arranged at the other end of a sliding part in the length direction, a first driving mechanism is used for driving a sliding seat assembly to move in the direction of the cutting assembly side, and the sliding seat assembly freely moves in the direction of the baffle assembly side; according to the automatic fixed-length cutting device for the profile clamping groove for cable laying and the control method, the distance between the cutting assembly and the baffle assembly is the fixed-length cutting distance; the sliding seat assembly freely moves towards the baffle assembly side, the whole sliding seat assembly can be driven to move by thrust on the baffle assembly in the extending process of the profile clamping groove, and the distance and speed of forward movement of the sliding seat assembly do not need to be accurately controlled by matching with a cor
