The implementation principle of the embodiment is as follows: before the steel plate 6 is drilled, the steel plate 6 is placed on the four groups of supporting plates 43, the driving assembly 42 drives the four groups of clamping plates 41 to be clamped on the steel plate 6 together, and the air cylinder 45 drives the pressing plate 47 to be pressed on the upper surface of the steel plate 6, so that the steel plate 6 is not prone to shaking in the drilling process.

In the process of drilling the steel plate 6, the lifting assembly drives all the drill bits 21 to synchronously descend, and the rotating member drives the drill bits 21 to rotationally drill the steel plate 6; meanwhile, the worker needs to place a group of steel plates 6 as the stock on the stock preparation table 31, then descend the horizontal shelf 321 through the vertical moving assembly 33, so that the vacuum chuck 323 adsorbs the stock, then drive the stock to ascend and return through the vertical moving assembly 33, and drive the stock to move to the drill bit 21 through the horizontal moving assembly 34 to wait for the stock exchange.

After the drilling of the steel plate 6 is completed, the hydraulic cylinder 22 drives the drill bit 21 to ascend to the top of the prepared material, the cylinder 45 drives the pressing plate 47 to ascend, the driving component 42 drives the clamping plate 41 to move away from the center of the steel plate 6, the steel plate 6 is separated from the supporting plate 43 and falls onto the inclined table 51 from the falling cavity 44, and then the driving component 42 drives the clamping plate 41 to gather together towards the center of the falling cavity 44.

When the driving member 42 drives the clamping plate 41 to move so that the abutting plate 48 is away from the pressing plate 47, the torsion spring 49 gradually returns to the natural state and urges the pressing plate 47 to rotate, so that the pressing plate 47 is no longer shielded from the steel plate 6.

When the drill bit 21 rises above the stock material, the horizontal moving assembly 34 will drive the stock material to move to the position right above the falling cavity 44, and then the vertical moving assembly 33 will drive the stock material to descend, so that the stock material is placed on the supporting plate 43 gathered to the center of the stock material; at this time, the driving assembly 42 still continues to drive the clamping plates 41 to gather toward the center of the stock material, so that the four groups of clamping plates 41 will be clamped together to the stock material and keep the stock material at the same processing position all the time.

When the prepared material descends to the lower part of the pressing plate 47, the air cylinder 45 also drives the pressing plate 47 to descend, the contact plate 48 driven by the driving component 42 pushes the pressing plate 47 to move to contact the pressing plate 47 and pushes the pressing plate 47 to rotate and shield the prepared material, so that the pressing plate 47 can be pressed on the upper surface of the prepared material, and the prepared material is pressed and fixed. The material changing of the steel plate 6 is completed at the moment, and most of working steps in the process are performed synchronously, so that the whole material changing process can be completed in only 6 seconds, and the machining efficiency of the steel plate 6 is greatly improved.

In the process that the vertical moving assembly 33 drives the prepared material to descend onto the supporting plate 43, the hydraulic cylinder 22 can drive the drill bit 21 to descend close to the prepared material, so that the time required by descending the drill bit 21 is saved; when the stock is laid on the support plate 43 and the stock is limited and fixed by the clamping plate 41 and the pressing plate 47, the drill 21 can continue to descend and drill the stock, thereby further improving the processing efficiency of the steel plate 6.

When the steel plate 6 falls from the falling cavity 44, the steel plate 6 is pressed against the guide roller 513 on the inclined block 511, the inclined block 511 where the guide roller 513 is located descends, and all the springs 516 on the inclined block 511 and the soft sleeves 514 outside the guide roller 513 deform and provide a buffering effect for the steel plate 6, so that the steel plate 6 is buffered for many times, and the surface of the steel plate 6 is not easy to collide and damage; the steel plate 6 will then slide down in the direction of the incline block 511 and will bring the guide rollers 513 into rotation, thereby facilitating the steel plate 6 to slide down onto the collection table 52 for collection.
