[0087] In the present technical solution, a large amount of waste chips will be generated when the drilling machine tool is processing, and a certain amount of heat will also be generated. The heat will affect the quality of the drilling. At the same time, the waste chips during the drilling process will cause additional wear, so it is necessary to set a lubricating liquid injection block 43 to ensure that the nut processing cavity 62 is always filled with lubricating liquid. The lubricating liquid can cool the processing part conveniently and also facilitate the discharge of waste chips.

[0088] In the present technical solution, an upper channel 54 and a lower channel 55 are provided to form two flow channels, and the two flow channels are respectively used to communicate the nut processing cavity 62 and the chip removal hole 63.

[0093] In the present technical solution, a pipeline 64 is provided to achieve communication with the lubricating liquid injection block 43, so that the lubricating liquid injection block 43 forms a whole, which is convenient for centralized and unified oil supply operation to the nut processing cavity 62, and at the same time, the docking pipelines at the two ends are used to realize the circulation of the lubricating liquid.

[0094] The lubricating fluid retained from the nut processing fixture 28 will be recovered at the bottom of the drilling rig 2, and filtered to ensure that the lubricating fluid is recovered again. At the same time, the filtered lubricating fluid is injected into the lubricating fluid injection block 43 again through an oil pump to achieve reasonable utilization of the lubricating fluid.

[0096] After the nut is drilled on the side, it needs to be pushed out by the pushing cylinder 39, but the nut needs to be prevented from falling from the nut fixing block 41, so a circle of limiting ribs needs to be set to control the extension amount of the main shaft of the pushing cylinder 39 to ensure that the length of the nut pushed out accounts for half of the total length of the nut.

[0097] As a supplement to the present technical solution, a sealing cover plate 52 is embedded and installed at the front side of the lubricating liquid injection block 43 .

[0098] As a supplement to the present technical solution, a protective cover structure is installed at the rear of the base plate structure 36, and a waste chip pusher assembly 35 is installed at one side of the nut processing fixture 28. The waste chip pusher assembly 35 adopts a cylinder structure, and a waste chip pusher block is installed on the main shaft of the cylinder structure.

[0099] Since two rows of longitudinal brackets 31 are provided on the magnetic nut fixing frame 4, and the two rows of longitudinal brackets 31 serve as two groups of nut picking structures, an air avoidance groove 8 is provided under the blow-drying air outlet 7 of the material rack body 6 to facilitate the magnetic nut fixing frame 4 to extend into the blow-drying air outlet 7 and avoid contact between the magnetic nut fixing frame 4 and the material rack body 6.

At the same time, the manipulator 1 in the device selects a conventional six-axis manipulator, such as the manipulators produced by Wuhu Luka Robot Technology Co., Ltd., Dongguan Minghao Automation Co., Ltd., etc., and the drilling machine 2 selects a conventional milling machine equipment that can be purchased on the market, which can perform drilling processing.

[0103] like Figure 1As shown, when the device is in production, first start the vibration plate 20 in the vibration plate bracket 5, arrange the unprocessed nuts one by one on the arrangement track 15, and then transfer the nuts one by one to the discharge rack 9 through the robot 1. The nut placement holes 21 on the discharge rack 9 can accommodate the nuts. The transfer action is that a product fixing head 34 of the magnetic nut fixing rack 4 on the robot 1 completes the placement of the nuts. After completion, a row of product fixing heads 34 adsorb the nuts on the discharge rack 9, and then all the nuts are placed on the lifting platform 45 through the robot 1. Then, the nuts are transported to a position at the same height as the nut fixing block 41 through the lifting platform 45, and the nuts on the lifting platform 45 are processed. The cavity 62 and the nut placement groove are aligned. After completion, the nut pushing cylinder 47 is started, and the nut pushing cylinder 47 pushes the nut into the nut processing cavity 62. The limiting protrusion on the lower side wall of the nut processing cavity 62 positions the nut. After completion, the drilling machine 2 is started, and the drill bit of the drilling machine 2 directly extends into the processing through hole 51 to drill the nut. After completion, the pushing cylinder 39 is started to push the nut out of the nut processing cavity 62, and then all the nuts are taken out through the magnetic nut fixing frame 4, and the processed nuts are sent to the drying air outlet 7 by the manipulator 1. The blowing pipe 24 in the drying air outlet 7 performs a blowing action. After completion, the manipulator 1 moves the nuts to the discharge chute 10 to facilitate the overall output of the product.

[0104] When the drilling machine 2 is performing drilling processing, the manipulator 2 controls the magnetic nut fixing frame 4 to perform the operation of arranging the nuts again, thereby realizing the continuous operation of the equipment.

[0105] Meanwhile, during the drilling process, the lubricating fluid injection block 43 needs to continuously output the lubricating fluid to ensure that appropriate lubricating fluid remains in the nut processing cavity 62 .
