[0050] By pressing the position adjusting button 503 to send a trigger signal to the controller, the controller sends a control signal (pulse signal) to the translation driving member 4021 to control the output shaft of the translation driving member 4021 to rotate forward and backward, and the screw rod 4023 follows the output shaft of the translation driving member 4021 to rotate forward and backward, and the screw rod 4023 drives the base 401 to reciprocate (slide) in the second direction.

[0051] When the output shaft of the translation driving member 4021 rotates forward, the translation driving member 4021 drives the bottom plate to move in the second direction to the direction close to the cutting device 3, the bottom plate drives the supporting seat 403, the connecting assembly 405, the transmission rod 406, the rotating plate, the base plate 4101 and the workpiece 200 to move in the second direction to the direction close to the cutting device 3, the slide column 407 slides in the straight slot 40811 to adjust the horizontal position of the workpiece 200, and the rotating plate 404 is parallel to the base 401; when the slide column 407 slides in the arc-shaped slot 40812 after being separated from the straight slot 40811, the slide column 407 drives the transmission rod 406 to rotate around the rotating shaft 4051, thereby driving the rotating shaft 4051 to rotate, driving the rotating plate 404 to rotate, and the angle between the rotating plate 404 and the base 401 changes from 0º to 90º, thereby adjusting the workpiece angle of the workpiece 200; when the slide column 407 is accommodated in the accommodation slot 40813 after being separated from the arc-shaped slot 40812, the rotating plate 404 stops rotating.

[0052] When the output shaft of the translation driving member 4021 rotates reversely, the above-mentioned components move reversely to reset.

[0053] The distance of the translation of the workpiece 200 or the angle of the rotation of the workpiece 200 can be controlled by the angular displacement of the translation driving member 4021, and the angular displacement of the translation driving member 4021 can be preset in the controller and controlled by the controller.

[0054] The straight slot 40811 is arranged for the slide column 407 to slide therein, the base 401 and the rotating plate 404 drive the workpiece 200 to move in the second direction, the horizontal position of the workpiece 200 is adjusted, so that the clamping device 4 can adapt to workpieces 200 of different sizes, and the applicability of the clamping device 4 is improved.

[0055] The horizontal position of the workpiece 200 or the tooling angle is adjusted, so that the riser of the workpiece 200 is directly opposite the saw blade of the cutting device 3, the cutting button 501 is pressed, the cutting button 501 sends a trigger signal to the controller, the controller sends a control signal to the cutting device 3 and the oil press, the oil press drives the lifting driving piece 2 to drive the cutting device 3 to reciprocatingly rise and fall in the third direction, and the cutting device 3 controls the saw blade to cut the riser of the workpiece 200 along the first direction (i.e. the left-right direction).

[0056] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields within the concept of the present application, and the contents of the present application specification and drawings are included in the patent protection scope of the present application.
