When in use, the position of the zero block 201 is adjusted by adjusting the adjustment component 1 2 and the adjustment component 2 3, and the position of the zero block 201 is the zeroing position. The depth direction of the fourth threaded rod 302 is the X-axis, and the depth direction of the third threaded rod 205 is the Y-axis. The fourth threaded rod 302 and the third threaded rod 205 are rotated by two knobs 207 to change the position of the cross bar 304 and the zero block 201 to return to the zero position.

[0039] The use method and advantages of the present invention: When the gantry laser welding machine zero adjustment mechanism is used, the working process is as follows:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when in use, the position of the zero block 201 is adjusted by adjusting component 1 2 and adjusting component 2 3, and the position of the zero block 201 is the zero position, the depth direction of the fourth threaded rod 302 is the X-axis, and the depth direction of the third threaded rod 205 is the Y-axis. The fourth threaded rod 302 and the third threaded rod 205 are rotated by two knobs 207, so that the position of the cross bar 304 and the zero block 201 changes and returns to the zero position. When the welding gun position at the bottom of the sliding sleeve 12 needs to be zeroed, the zeroing operation is performed through the control panel and the second drive motor 15 and the first drive motor 8 are started by the embedded control program to perform the zeroing behavior, so that the block 14 at the top of the sliding sleeve 12 is in contact with the plates 402 on the two alarm components 4, and the switch is connected before resetting. Circuit, and the two alarm components 4 are connected in parallel with the buzzer 16 and the LED light 17, while the buzzer 16 and the LED light 17 are connected in series. After the circuit is connected, the first electric sheet 404 and the second electric sheet 407 are abutted under the force of the tension spring 405, and the circuit forms a complete path, and the buzzer 16 and the LED light 17 work. After the stop block 14 is completely reset, the first electric sheet 404 and the second electric sheet 407 are separated, so that the buzzer 16 and the LED light 17 no longer work. Due to the parallel connection, when the stop block 14 is only completely reset on one axis of the X and Y axes, but not completely reset on the other axis, the buzzer 16 and the LED light 17 still work to alarm. After it is not completely reset, the second drive motor 15 or the first drive motor 8 can be manually started until the stop block 14 moves to the zero position.
