[0045] A method for using a linkage drilling device comprises the following steps:

[0046] S1: Place the linkage to be processed on the clamping head 45, push the mounting plate 43 through the clamping drive cylinder 42, so that the clamping head 45 clamps the linkage, and the auxiliary clamping assembly 46 drives the screw 467 to rotate by rotating the knob 468, so that the slider 465 slides in the housing 464, and adjusts the position of the pressing block 466 to achieve auxiliary clamping of the linkage, ensuring its stability during the processing;

[0047] S2: Start the rotation drive motor 51, the motor output end is connected to the driving gear 52, the driving gear 52 drives the driven gear 53 and the locking gear 54 to rotate, so as to adjust the angle of the linkage. According to the needs, the rotation drive motor 51 makes the linkage reach the preset angle position;

[0048] S3: When the linkage is adjusted to a suitable angle, the locking handle 57 is rotated to thread the locking bolt 56 with the first thread groove 541 and the second thread groove 551 respectively to lock the position of the linkage. This step ensures that the angle of the linkage remains unchanged during the drilling process to prevent deviation.

[0049] S4: Start the drilling drive cylinder 22. The output end of the drilling drive cylinder 22 is connected to the connecting plate 23. The bottom of the connecting plate 23 is fixedly installed with a drilling drive motor 24 and a drill bit 25. The drilling drive cylinder 22 pushes the connecting plate 23 to slide inside the bracket 21, driving the drill bit 25 to perform a drilling operation on the linkage.

[0050] S5: As needed, adjust the stroke of the drilling drive cylinder 22 and the speed of the drilling drive motor 24 to control the drilling depth and speed to ensure the accuracy and stability of the drilling process;

[0051] S6: After the drilling operation is completed, the slide 32 is driven by the sliding drive cylinder 31 to slide on the slide rail 33, and the slide 32 is slid out of the bracket 21. This step facilitates the operator to take and place the linkage, improves the safety of the operation, and avoids injuries to the operator.

[0052] Working principle: Place the linkage to be processed on the clamping head 45, push the mounting plate 43 through the clamping drive cylinder 42, so that the clamping head 45 clamps the linkage, and further fixes the linkage through the auxiliary clamping assembly 46, the auxiliary clamping assembly 46 includes a connecting block 462, a shell 464, a slider 465, a pressure block 466 and a screw 467, and the screw 467 is driven to rotate by rotating the knob 468 to make the slider 465 slide in the shell 464, and the position of the pressure block 466 is adjusted to achieve auxiliary clamping of the linkage to ensure its stability during the processing. Next, start the rotary drive motor 51, and the output end of the motor is connected to the driving gear 52, and the driving gear 52 drives the driven gear 53 and the locking gear 54 to rotate, thereby adjusting the angle of the linkage. When the angle is adjusted to the appropriate position, the locking handle 57 is rotated to make the locking bolt 56 threadedly connected with the No. 1 thread groove 541 and the No. 2 thread groove 551 respectively. Next, the position of the linkage is locked to prevent it from angular displacement during the drilling process, and then the drilling drive cylinder 22 is started. The output end of the drilling drive cylinder 22 is connected to a connecting plate 23, and a drilling drive motor 24 and a drill bit 25 are fixedly installed at the bottom of the connecting plate 23. The drilling drive cylinder 22 drives the connecting plate 23 to slide inside the bracket 21, driving the drill bit 25 to perform drilling operations on the linkage. The drilling depth and speed are controlled by adjusting the stroke of the drilling drive cylinder 22 and the rotation speed of the drilling drive motor 24. In addition, the sliding drive cylinder 31 drives the slide 32 to slide on the slide rail 33, so as to adjust the drilling position and improve the flexibility and applicability of drilling. When the linkage needs to be taken and placed, the sliding drive cylinder 31 slides the slide 32 out of the bracket 21, so that the operator can safely take and place the linkage to prevent personal injury.
