[0003] Through the search, patent application No. CN202421035271.6 discloses a brake pad drilling device, which realizes the movement of the base and the moving block through the electric push rod and the fixed motor, so as to adjust the position of the limited brake pad workpiece. Although the device can adjust the position of the brake pad to a certain extent to adapt to the drilling needs of different models of brake pads by setting the moving assembly, the device is relatively single in the clamping and fixing mode of the brake pad, and only relies on the limiting of the positioning block, the fixed plate and other components, so it is difficult to flexibly adjust the clamping force and angle according to brake pads of different sizes and shapes, and it is impossible to ensure that all kinds of brake pads can always maintain a stable fixed state during drilling, which may cause drilling deviation due to loose clamping. Moreover, the structure layout of the device is not compact, and the cooperative operation efficiency of the components is not high, so it is not convenient and efficient to adjust the position of the machine head to align different drilling positions.

[0040] Working principle:

[0041] Place the brake pad 8 that needs to be drilled on the fixed tooling 9. The fixed tooling 9 is provided with a turntable 902, and the clamp block 901 is rotatably installed on the turntable 902 through a pin shaft. This structure provides a basis for subsequent clamping of the brake pad 8.

[0042] The second cylinder 904 is started, and the second cylinder 904 pushes the lever 905. According to the principle of the lever 905, the lever 905 is deflected with the support rod 906 as the center. One end of the lever 905 is provided with a connecting head 903, and the connecting head 903 is clamped and fixed with a sleeve 907 rotatably installed on the transmission shaft of the motor 12 through a bearing. Therefore, when the lever 905 is deflected, the sleeve 907 is lifted and lowered. The sleeve 907 is rotatably connected with a connecting rod 908, and the connecting rod 908 is in transmission connection with one end of the clamp block 901. When the sleeve 907 is lifted and lowered, the clamp block 901 is pulled through the connecting rod 908, so that the clamp block 901 is deflected. Since the clamp block 901 is installed on the rotating disc 902, the clamp block 901 is deflected to clamp and fix the brake pad 8. In this process, the spring 909 provided on the connecting rod 908 plays an auxiliary resetting role. When the clamp block 901 releases the brake pad 8, the elastic force of the spring 909 can help the connecting rod 908 and the clamp block 901 quickly return to the initial position, which is convenient for subsequent operation.

[0043] The linear module 2 and the slide rail 3 are installed on the base 4, the mounting frame 5 is slidably installed on the base 4 through the linear module 2 and the slide rail 3, and the head 7 is installed on the mounting frame 5. By controlling the linear module 2, the mounting frame 5 can be moved along the slide rail 3, and the position of the head 7 is adjusted to align the position of the brake pad 8 that needs to be drilled.

[0044] The support frame 11 is installed on the rack 10, and the motor 12 installed on the support frame 11 is started. The output end of the motor 12 is connected and fixed with the fixed tooling 9, and the motor 12 drives the rotating disc 902 of the fixed tooling 9 to rotate, so as to drive the clamped brake pad 8 to rotate and adjust the position. At the same time, the first cylinder 6 installed on the mounting frame 5 is started, the first cylinder 6 pushes the head 7 to move downward, and the drilling tool on the head 7 performs drilling operation on the rotating brake pad 8. In this process, the first cylinder 6 controls the up-down movement of the head 7 to realize the drilling action.

[0045] After the drilling of one position is completed, the first cylinder 6 drives the head 7 to rise and reset. If drilling is required at other positions of the brake pad 8, the position of the head 7 can be adjusted again through the linear module 2, and the drilling operation is repeated in step 4. After all the drilling is completed, the second cylinder 904 is reversely operated, the lever 905 drives the sleeve 907 to descend, the clamp block 901 is released through the connecting rod 908, the processed brake pad 8 is taken out, and the whole working process is completed.
