[0016] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic drilling method for wind power flange finishing:

[0017] S1: The present invention allows the user to place the flange on the top of the tray, and then start the two electric push rods and the drilling machine to work. The electric push rod retracts and drives the two first tooth plates to move. The movement of the first tooth plates drives the first gear and the transmission shaft to rotate.

The movement of the two second tooth plates drives the second gear and the rotating rod to rotate. The rotation of the rotating rod drives the tray to rotate, so that the drilling position is changed. Since the rotating rod is movably connected to the second gear through a one-way bearing, the rotation of the second gear will not drive the rotating rod to rotate when the drilling machine moves downward, so it will not affect the operation of the drilling machine.

[0018] S2: At the same time, the bottom plate moves to drive the four connecting rods to move, and the movement of the connecting rods drives the two shielding soft plates to move downward. The shielding soft plates move downward to shield the drilling position to prevent iron filings from splashing and causing harm to workers. When the drilling machine moves upward, the two shielding soft plates are rolled up on the outside of the spiral spring due to the spiral spring, so as to facilitate the next use.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention allows the user to place the flange on the top of the tray, and then start the two electric push rods and the drilling machine to work, so that the two electric push rods reciprocate and extend, thereby driving the drilling machine to move up and down. The drilling machine moves down to drill holes in the flange. When the drilling machine moves up, the two second piston plates are pushed by air pressure to rotate the rotating rod, thereby changing the drilling position to facilitate the next drilling. The device improves the efficiency of drilling holes in the flange, and at the same time, the device reduces human intervention and reduces cost losses for producers;

[0021] 2. In addition, when the drilling machine moves downward, it drives the front and rear two shielding soft plates to move downward, so that the shielding soft plates can shield the drilling position to prevent iron filings from splashing and causing harm to workers. When the drilling machine moves upward, the two shielding soft plates are rolled up on the outside of the spiral spring due to the spiral spring, so as to facilitate the next use. This device improves the safety of flange drilling production, prevents workers from being injured, and brings great benefits to producers. BRIEF DESCRIPTION OF THE DRAWINGS
