7. The automatic alignment mechanism of a punching die according to claim 6, characterized in that a protection shield (14) is welded to the bottom of the surface of the displacement seat (3), and the protection shield (14) is covered on the top of the guide rail (2).
8. The automatic alignment mechanism of a stamping die according to claim 7, characterized in that limiting strips (16) are welded on both sides of the displacement toothed plate (55), and limiting sliding grooves (17) for the sliding of the limiting strips (16) are opened on both sides of the inner cavity of the guide rail (2).
9. The automatic alignment mechanism of the stamping die according to claim 8, characterized in that a guide gear (18) engaged with the displacement toothed plate (55) is arranged at the front side of the inner cavity of the guide rail (2), and both ends of the guide gear (18) are rotatably connected with the inner wall of the guide rail (2) through a third bearing.
10. The automatic alignment mechanism of a press die according to any one of claims 1 to 9, characterized in that its automatic alignment method is as follows:
firstly, when a user uses the processing carrier plate (10), the processing carrier plate (10) is pulled towards the front side from a positioning frame (61), a guide post (62) slides along with the pulling process, meanwhile, a return spring (63) is compressed, a workpiece to be punched is placed at the top of the processing carrier plate (10) by the user, then the processing carrier plate (10) is sent back to an inner cavity of the positioning frame (61), and the processing carrier plate (10) drives the workpiece to move to be under a stamping part butt joint plate (15);
secondly, the infrared emitter (12) is powered on to enter a working state and emits infrared light signals downwards, if the infrared light signals vertically irradiate the top of the light-transmitting lens cone (13), the infrared light signals are intercepted by the deviated processing carrier plate (10), the position of the infrared emitter (12) is indirectly adjusted horizontally and vertically through the matching use of the longitudinal alignment assembly (5) and the transverse alignment assembly (4), so that the infrared light signals of the infrared emitter (12) vertically irradiate the top of the light-transmitting lens cone (13), after the infrared light signals irradiate the top of the light-transmitting lens cone (13), the infrared light signals are in a transmitting state, and the stamping cylinder (7) can be powered on and enter the working state;
thirdly, in the process of transversely moving the position of the infrared emitter (12), the stepping motor I (42) drives the driving screw rod (43) to rotate, in the process of rotating the driving screw rod (43), the positioning threaded sleeve (44) is driven to move left and right through surface threads of the driving screw rod, and then under the driving of the positioning threaded sleeve (44), the fixed sleeve (8) drives the stamping cylinder (7) to move between the two displacement seats (3) so as to find an accurate stamping position;
fourthly, in the process of longitudinally moving the position of the infrared emitter (12), a second stepping motor (51) drives a driving column (52) to rotate through a belt pulley (53), then a driving fluted disc (54) is driven to rotate in the inner cavity of the guide rail (2), and when the driving fluted disc (54) rotates, under the meshing action of the driving fluted disc (54) and a displacement toothed plate (55), the displacement toothed plate (55) drives a displacement seat (3) to displace back and forth in the inner cavity of the guide rail (2), so that the positions of the stamping cylinder (7), the fixed sleeve (8) and the guide plate (9) are all displaced;
fifthly, finally, under the propulsion of a stamping part butt joint plate (15) by a stamping cylinder (7), stamping a machined part positioned at the top of the processing carrier plate (10);
the light states generated by the infrared emitter (12) in the using process are calculated by the optical signal processor, the calculation results are transmitted to the motor controller, and the motor controller adjusts the running state of the motor.
