A steel intelligent drilling device based on five-axis CNC processing, the drilling method of the steel intelligent drilling device is:

Step 1: Fix the steel to be processed by the clamping tool, and open the punching tool and the control valve, so that when the punching tool punches holes in the steel, the grinding oil sprayed from the output end of the spray pipe washes and cools the surface of the steel, and the splashing grinding oil and debris are shielded by the shielding sleeve, and the grinding oil mixed with the debris is guided into the opening with the help of the guide cover, and then flows into the oil storage box to collect the grinding oil and debris;

Step 2: When the grinding oil in the oil storage box is full and the liquid level submerges the stirring paddle, the motor is turned on to cooperate with the rotating shaft to drive the stirring paddle to rotate, so that the grinding oil in the oil storage box rotates to generate a vortex, so that all the debris is accumulated in the middle of the oil storage box, and the extended end of the cylinder is extended to the longest, so that the bottom of the first piston is higher than the bottom of the bottom wall of the oil storage box, and the accumulated debris and the surrounding grinding oil are sucked into the collection barrel.

Compared with the prior art, the present invention has the following beneficial effects:

1. In the present invention, when the grinding oil in the oil storage box is full and the liquid level submerges the stirring paddle, the stirring paddle rotates to make the grinding oil in the oil storage box rotate and generate a vortex, so that all the debris are accumulated in the middle of the oil storage box, and the extended end of the cylinder is extended to the longest, and the accumulated debris together with the surrounding grinding oil are sucked into the collection bucket, and then the extended end of the cylinder is controlled to shrink to the shortest, and the first piston is lowered to the bottom of the inner wall of the first discharge pipe. At this time, the top wall height of the second piston corresponds to the input end position of the third discharge pipe, and the grinding oil carrying the debris will enter the filter box through the third discharge pipe for recovery and filtration. The above process is convenient for efficient and complete recovery of the debris, while not affecting the efficiency of grinding oil recovery;

2. In the present invention, when the grinding oil in the oil storage box rotates to generate a vortex, the grinding oil is sucked through the recovery pipe and then injected into the oil storage barrel through the oil return pipe. Since all the debris is accumulated in the middle of the oil storage box, the grinding oil sucked from the edge of the inner wall of the oil storage box does not contain debris. Therefore, the grinding oil sprayed out from the output end of the spray pipe can avoid scratching the surface of the steel when washing and cooling it, thereby ensuring the product quality of the steel.

The structure is not limited, and it only needs to have the above-mentioned functions for steel, which will not be elaborated here.

The working process and principle of the present invention are as follows:

Step 1: Fix the steel material to be processed by the clamping tool 7, open the punching tool 9 and the control valve 105 by external remote control, so that when the punching tool 9 punches holes in the steel material, the grinding oil sprayed from the output end of the spray pipe 104 washes and cools the surface of the steel material, and the splashing grinding oil and debris are shielded by the shielding sleeve 6 to prevent pollution of the surrounding environment and avoid affecting the normal operation of the CNC machine tool. The grinding oil mixed with the debris is introduced into the opening 11 with the help of the guide cover 14, and then flows into the oil storage box 54 to collect the grinding oil and debris;

Step 2: When the grinding oil in the oil storage box 54 is full and the liquid level submerges the stirring paddle 51, the motor 12 is turned on to cooperate with the rotating shaft 55 to drive the stirring paddle 51 to rotate, so that the grinding oil in the oil storage box 54 rotates to generate a vortex, so that all the debris is accumulated in the middle of the oil storage box 54, and the extended end of the cylinder 533 is extended to the longest, so that the bottom of the first piston 537 is higher than the bottom of the bottom wall of the oil storage box 54, and the accumulated debris and the surrounding grinding oil are sucked into the collection barrel 535.

The above process facilitates efficient and complete recovery of the debris without affecting the efficiency of grinding oil recovery.

Since all the debris is accumulated in the middle of the oil storage box 54, the grinding oil absorbed from the edge of the inner wall of the oil storage box 54 does not contain debris. Therefore, the grinding oil sprayed out from the output end of the spray pipe 104 can avoid scratching the surface of the steel when flushing and cooling it, thereby ensuring the product quality of the steel.
