Two Y-direction linear guide rails 2 are arranged on a machine frame, namely a mounting platform 1, and a Y-direction moving platform 3, namely a cutting and feeding platform, is movably arranged on the Y-direction linear guide rails 2. The Y-direction moving platform 3 is provided with a connecting frame 4, and the servo linear motor 5 consists of a stator 52 and a rotor 51. The coupling frame 4 is coupled to the mover 51, and the fixing member 52 is fixed to the mounting platform 1. The mover and the stator of the linear motor are opposite. The mover 51 may be fixed as a stator, and the stator 52 may be connected to the cutting feed table as a mover. . This is also due to the peculiarities of linear motors.
The servo linear motor 5 is not capable of carrying, so that all the load of the cutting feed platform, i.e. the Y-direction motion platform 3 and the objects thereon, is borne by the two Y-direction linear guides 2. The rotor is connected with the Y-direction motion platform 3 through the connecting frame 4, the stator 52 of the servo linear motor 5 is connected with the fixed mounting platform 1, namely the rack, the servo linear motor 3 is started, and the Y-direction motion platform 3 can reciprocate along the Y-direction linear guide rail 2 to realize the sawing function.
Two X-direction linear guide rails 6 are arranged on the Y-direction moving platform 3. An X-direction moving platform 7, namely a material bearing platform, is movably arranged on the X-direction linear guide rail 6. A screw nut connecting frame 9 is arranged on the X-direction moving platform 7, and a screw nut 10 is fixed with the screw nut connecting frame 9 through a screw. The ball screw 11 passes through the screw nut 10, two ends of the ball screw 11 respectively pass through the screw mounting rack 8 and can freely rotate and cannot move, and the screw mounting rack 8 is fixed on the Y-direction motion platform 3. The X-direction linear guide 6 is arranged perpendicular to the Y-direction linear guide 2.
Two ends of the ball screw 11 are respectively and fixedly provided with a redirection collision head: the tool retracting and direction changing collision head comprises a tool retracting and direction changing collision head A12 and a resetting and direction changing collision head B15, wherein the two direction changing collision heads are cams which radially extend out of a section relative to the axis of the screw rod, are obliquely arranged on the ball screw rod 11 relative to the axis center line of the ball screw rod, and are opposite in oblique direction. Accordingly, two direction-changing bumps are mounted on the mounting platform 1 in the Y-direction moving direction. The tool retracting redirection collision block 13 and the reset redirection collision block 16.
Two cams with the same shape and the opposite installation directions of the cutter retracting redirection collision head A12 and the resetting redirection collision head B15 are respectively fixed at two ends of the ball screw 11, and the rotation of the cams drives the rotation of the ball screw 11. The ball screw 11 is connected with the Y-direction motion platform 3 through a screw mounting rack 8; the tool retracting direction changing collision block 13 and the resetting direction changing collision block 16 are respectively fixed on preset positions on the mounting platform 1.

According to the motion principle of the lead screw and nut pair, the X-direction motion platform 7 moves rightwards relative to the Y-direction motion platform 3 (see figure 1). Because the cam structure characteristics of the ram and the shape structure of the ram are matched, the ram only rotates 90 degrees in the process of movement, so that the ball screw 11 only rotates 1/4 turns along with the ram, and therefore, the X-direction moving platform 7 moves rightwards by a corresponding distance. Thereby achieving the purpose of retracting the cutter. When the mover 51 of the servo linear motor 5 reaches the set stroke, the direction is changed according to the set program to drive the Y-direction moving platform 3 to retreat. In the process that the rotor 51 of the servo linear motor 5 moves back, the redirection collision head B15 collides with the redirection collision block 13, at this time, the rotor 51 of the servo linear motor 5 continues to move forward, the roller screw 11 rotates 90 degrees in a rotating direction, at this time, the X-direction motion platform 7 moves leftwards for a set distance, so that the X-direction motion platform and the Y-direction motion platform are restored to the initial state, and the Y-direction motion platform 3 is also restored to the initial position under the driving of the servo linear motor 5. When all the moving parts including the Y-direction moving platform 3, the X-direction moving platform 7 and the redirection collisions A12 and B15 reach the initial positions, one cycle is completed, and the next cycle is entered according to the set program.

In the original state, the direction-changing collision head B15 is above the direction-changing collision block 13, and the servo linear motor is started to drive the Y-direction motion platform 3 to move forwards, because the screw rod is fixed on the Y-direction motion platform 3. When the direction-changing ram A12 hits the direction-changing ram 16, the screw nut 10 drives the X-direction moving platform 7 to move right 1/4 distance of the ball screw 11 stroke through the screw nut connecting frame 9. Thereby achieving the purpose of retracting the cutter. When the servo linear motor moves back, the direction-changing collision head B15 collides with the direction-changing collision block 13, so that the X-direction motion platform 7 moves leftwards to return to the original position.
