[0023] Working process of this utility model:

[0024] During the working process of the automatic tapping device of the utility model, the feeding device 20 feeds a hexagonal nut semi-finished product into the processing pipe 2, and the hexagonal nut semi-finished product falls onto the baffle 6 below the processing pipe 2 under the action of gravity. Since the length of the inner part of the horizontal cross-section of the processing pipe 2 is 1.1-1.3 times the diameter of the circumscribed circle of the hexagonal nut semi-finished product, the hexagonal nut semi-finished product will eventually have a side wall that fits with the baffle 6, and then the two first push-pull devices 30 drive the two clamping blocks 3 to move synchronously relative to each other, and the two clamping blocks 3 pass through the opening window 21 to clamp the hexagonal nut semi-finished product, and then the second push-pull device 41 drives the first motor 40 to move toward the hexagonal nut semi-finished product, and the drilling drill 4 on the first motor 40 drills a hole in the hexagonal nut. The nut semi-finished product is drilled, and then the second push-pull device 41 drives the first motor 40 to reset, and then the third push-pull device 51 drives the second motor 50 to move toward the hexagonal nut semi-finished product, and the tapping drill 5 on the second motor 50 taps the hexagonal nut semi-finished product after drilling, and then the third push-pull device 51 drives the second motor 50 to reset, and the liquid spraying pipe 10 continuously sprays cooling lubricating liquid during the drilling and tapping process. After the tapping is completed, the third motor 6 drives the baffle 60 to rotate one circle. In this process, when the baffle 6 is completely out of contact with the hexagonal nut, the hexagonal nut falls off. After the baffle 6 rotates, the feeding device 20 feeds a new hexagonal nut semi-finished product into the processing pipeline 2, and then continues according to the above steps. In the above process, the feeding device 20, the first motor 40, the second motor 50, the third motor 60, the first push-pull device 30, the second push-pull device 41, and the third push-pull device 51 are all controlled by the control device.

[0025] When the laser receiver 52 cannot receive the laser from the laser generator 42, the feedback from the laser receiver 52 to the control device will cause the control device to stop the equipment and issue a corresponding alarm message, reminding the operator to check whether the first motor 50 and the second motor 60 have a relative position deviation.

[0026] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
