[0022] By adopting the above technical solution, the cooled material after use can be filtered, thus facilitating its subsequent reuse.

[0023] The bottom of the control panel 1 is fixed with support legs 14 arranged in a rectangular array.

[0024] By adopting the above technical solution, the support leg 14 supports the entire device.

[0025] An auxiliary rod 28 is fixedly installed inside the control panel 1, and the auxiliary rod 28 is movably inserted into two movable frames 21.

[0028] By adopting the above technical solution, the placement rack 13 can place the metal plate to be processed.

[0029] The transmission rod 3 has symmetrically distributed slots on its outer side, and the transmission shaft 31 is movably inserted into the slots.

[0030] By adopting the above technical solution, the transmission shaft 31 can slide on the outside of the transmission rod 3, and the rotation of the transmission rod 3 can drive the transmission shaft 31 to rotate through the slot.

[0031] A No. 1 motor 12 is installed on the outside of the operating table 1. The output end of the No. 1 motor 12 is inserted through the operating table 1 and fixedly connected to the bidirectional threaded rod 2.

[0034] By adopting the above technical solution, one of the transmission rods 3 rotates through the synchronous pulley and the synchronous belt, causing the two transmission rods 3 to rotate synchronously.

[0035] Working principle: First, the metal plate to be processed is placed on the placement rack 13. Then, motor 12 is started, causing it to rotate. The output of motor 12 rotates the bidirectional threaded rod 2, which in turn rotates the two moving frames 21 in opposite directions. The movement of the moving frames 21 moves the fixed frame 22, thus allowing the metal plate to be clamped laterally. Next, motor 34 is started, causing it to rotate. The output of motor 34 rotates one of the transmission rods 3, which in turn rotates the transmission shaft 31 through the slot. The rotation of the transmission shaft 31 then rotates the first conical... Gear 32 rotates, and the first bevel gear 32 rotates, driving the meshing second bevel gear 33 to rotate. The second bevel gear 33 rotates, driving the one-way threaded rod 24 to rotate. The one-way threaded rod 24 rotates, driving the threaded slider 25 to rotate. The threaded slider 25 moves, driving the clamping plate 26 to move. The clamping plate 26 and the fixed block 23 can vertically clamp and position the metal plate, which can significantly improve the stability and accuracy of the processing, effectively reduce the positional displacement of the metal plate caused by cutting force or vibration during milling, and ensure the consistency and dimensional accuracy of micro-hole processing. Then, the metal plate can be continuously milled using the drilling assembly 11.

[0036] During the processing, coolant is used to cool the drilled area. The collected coolant enters the processing tank 41 through the slope 43 and the square groove 4. The coolant is then filtered through the processing tank 41 and finally enters the collection tank 42. The coolant can be reused, thereby reducing the cost of use.
