In this embodiment, the cooling water pipe 4220 and the cleaning water pipe 4230 are communicated with the water collecting tank through a water pump controlled separately, and cleaning water and cooling water can be recycled.

Because the second transmission mechanism 6200 is located outside the workbench 1000, in order to improve the safety of the working environment, a cover 6220 is disposed outside the second transmission mechanism 6200, and a chip removal port is disposed at one end of the cover 6220 away from the first transmission mechanism 6100. In this embodiment, the first conveying mechanism 6100 and the second conveying mechanism 6200 are respectively controlled to convey by two discharging motors 6210.

The implementation principle of the automatic drilling equipment for the rack in the embodiment of the application is as follows:

the racks 5000 are orderly stacked on the placing plate 1810, and then the placing plate 1810 is driven to a position where the stacked racks 5000 correspond to the mounting rod 1300.

During feeding, the driving motor 1230 drives the mounting seat 1200 to the upper side of the rack mounting rack 1800, and then the lifting motor 1420 is started to drive the mounting rod 1300 to move towards the direction of the rack 5000. When the detection device 1700 detects that the distance between the rack 5000 and the mounting rod 1300 is smaller than a set value, the control device turns on the electromagnet 1500 to adsorb the rack 5000 onto the electromagnet 1500. The driving motor 1230 is then activated to move the mounting rod 1300 toward the tool 2000, so that the rack 5000 is automatically transferred to the base 2110 position of the tool 2000. The electromagnets 1500 on both sides of this action can be done simultaneously or separately, but the time to drop into the base 2110 of the tool 2000 is both fore and aft.

Rack 5000 is placed on base 2110 and first hydraulic cylinder 2320 is then actuated to bring the other end of rack 5000 into contact with stop 2310 using push plate 2330. Then, the second hydraulic cylinder is started, the piston of the second hydraulic cylinder is ejected outwards, and the first tightening block 2240 rotates to push the rack 5000 towards the side seat 2120 until the rack 5000 abuts against the side seat 2120. And then the third hydraulic cylinder is started, the piston of the third hydraulic cylinder is ejected outwards, and the second abutting block 2430 rotates to push the rack 5000 to the direction of the base 2110. Thereby fixedly mounting the rack 5000 on the tool 2000.

The drill bit 3000 is then activated while the cooling jets are spraying water. And after the drilling is finished, closing the cooling spray head. At the same time, the driving motor 1230 drives the mounting seat 1200 to above the rack drilling apparatus, and then the lifting motor 1420 is started to drive the mounting rod 1300 to move toward the rack 5000. When the detection device 1700 detects that the distance between the rack 5000 and the mounting rod 1300 is smaller than a set value, the control device turns on the electromagnet 1500 to adsorb the rack 5000 onto the electromagnet 1500. The drive motor 1230 is then activated to move the mounting bar 1300 toward the rack mount 1800, thereby automatically returning the rack 5000 onto the placing plate 1810. The electromagnet 1500 on the other side puts the other rack 5000 into the tool 2000, so that seamless drilling can be performed, and the drilling efficiency is improved.

In addition, when the tool 2000 is in an unloaded state, the cleaning nozzle sprays water to clean the unloaded tool 2000 by spraying water, so that the scraps on the tool 2000 can be discharged from the scrap discharge hole 2113, the first water discharge hole 4111 and the second water discharge hole 4112 to the first conveying mechanism 6100 along with water flow, and then the scraps are discharged through the second conveying mechanism 6200.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
