[0002] Drilling and milling is a machine tool processing technology that combines drilling and milling. Compared with traditional drilling and milling, drilling and milling can complete the processing of complex shapes on the same equipment, greatly improving the processing efficiency and precision. The main cutting tools for drilling and milling are drills and milling cutters. Drills are used for drilling, while milling cutters are used for milling. These two tools can be used alternately to complete the processing of complex shapes. Drilling and milling are mainly used to process complex parts and workpieces, such as automobile engine parts, aircraft engine parts, molds, medical equipment and electronic components.
[0003] Most existing drilling and milling machines generally adopt manual loading and unloading when processing workpieces.

The bottom of the support frame 101 is connected to a plurality of support feet 1 distributed in a rectangular shape by welding, and an anti-sliding block is provided at the bottom of the support foot 1. The upper part of the support frame 101 is connected to the cylinder 2 by bolts, and the telescopic rod of the cylinder 2 is connected to the lifting plate 3 by welding. The lifting plate 3 is slidably connected to the support frame 101 to improve the lifting plate when moving. Stability, the right side of the lifting plate 3 is connected to the motor Ⅰ4 by bolts, and the output shaft of the motor Ⅰ4 is connected to the drill bit 5 for drilling the workpiece by bolts. The left side of the support frame 101 is connected to the storage frame 6 for placing the workpiece by welding. The feed port of the storage frame 6 is provided with a plurality of guide slopes distributed in the shape of a flat-topped cone. The lower part of the storage frame 6 is connected to the front and rear distributed limit rods 8 by welding. The two horizontally aligned limit rods 8 are externally slidably connected to the connecting plate 7. The connecting plate 7 is connected to the receiving block 71 by welding. The receiving block 71 penetrates into the lower part of the storage frame 6. The limit rod 8 is externally sleeved with a spring 81 for auxiliary resetting, and the two ends of the spring 81 are respectively connected to the connecting plate 7 and the storage frame 6 , the left and right sides of the connecting plate 7 are connected with wedge blocks 9 by welding, the wedge blocks 9 are located outside the storage frame 6, and the left side of the lifting plate 3 is connected with a push rod 10 equal to the number of wedge blocks 9 by welding. The push rod 10 is located directly above the corresponding wedge block 9, so that when the lifting plate 3 moves downward, the push rod 10 accurately squeezes the wedge block 9, and the lower part of the support frame 101 is connected with a support rod 11 by welding. The upper part of the support rod 11 is connected with a motor II 12 by bolts. The top of the support rod 11 is rotatably connected with a rotating disk 13, and the output shaft of the motor II 12 is fixedly connected to the rotating disk 13. The left and right sides of the rotating disk 13 are rotatably connected with a connecting shaft 151, and the end of the connecting shaft 151 away from the rotating disk 13 is connected by welding. There is a receiving seat 14 for receiving the workpiece, and the receiving groove inside the receiving seat 14 matches the size of the workpiece. The connecting shaft 151 is sleeved with a torsion spring 16 for auxiliary resetting. The two ends of the torsion spring 16 are respectively connected to the rotating disk 13 and the receiving seat 14. The ends of the two connecting shafts 151 close to each other are connected to the gear 15 by welding. The upper end of the support rod 11 is connected to the arc rack 17 by welding. The number of teeth of the gear 15 is equal to three times the number of teeth of the arc rack 17, so that the gear 15 rotates 120 degrees when the arc rack 17 completes one meshing. The front side of the lower part of the support frame 101 is connected to the collection frame 18 by bolts. The bottom of the collection frame 18 is provided with an inclined surface, and the inner wall is provided with a fully paved soft cushion.The outer surface of the rear side of the collection frame 18 and the outer surface of the front side of the receiving seat 14 are on the same vertical plane, so that when the receiving seat 14 rotates to 120 degrees, it is completely located above the inside of the collection frame 18 to pour out the workpiece. By controlling the telescopic rod of the cylinder 2 to extend, the lifting plate 3 drives the push rod 10 to move downward to squeeze the wedge block 9, so that the connecting plate 7 drives the receiving block 71 to move outward, and then the workpiece inside the storage frame 6 falls into the inside of the receiving seat 14 on the left side, and then the motor II 12 is operated, so that the rotating disk 13 drives the two receiving seats 14 to rotate 180 degrees to exchange positions.
[0025] First, the staff pours a proper amount of workpieces to be processed into the storage frame 6. The first workpiece from the bottom to the top in the storage frame 6 contacts and is held against the receiving block 71. Then, the cylinder 2 is turned on to control the telescopic rod of the cylinder 2 to extend. The lifting plate 3 drives the push rod 10 to move downward to squeeze the wedge block 9, thereby causing the wedge block 9 to drive the connecting plate 7 to move outward. The spring 81 is stretched accordingly, and the connecting plate 7 drives the receiving block 71 to move outward and no longer holds against the first workpiece, thereby causing the first workpiece in the storage frame 6 to fall into the receiving seat 14 on the left, thereby achieving the purpose of automatic loading. Then, the telescopic rod of the cylinder 2 is controlled to retract. The lifting plate 3 drives the push rod 10 to move upward and disengage from the wedge block 9, and the spring 81 returns to its original state, so that the connecting plate 7 drives the receiving block 71 to move inward to resist the second workpiece in the storage frame 6, and then the motor Ⅱ 12 is turned on, and the output shaft of the motor Ⅱ 12 rotates to drive the rotating disk 13 to rotate clockwise, and the rotating disk 13 drives the two receiving seats 14 to rotate clockwise. When the two receiving seats 14 rotate to 180 degrees and exchange positions, the motor Ⅱ 12 is turned off, and then the telescopic rod of the cylinder 2 is controlled to extend again, so that the second workpiece in the storage frame 6 falls into the receiving seat 14 on the left, and the lifting plate 3 moves downward. When the drill bit 5 moves to a suitable position and contacts the workpiece in the right receiving seat 14, the motor I4 is turned on, and the output shaft of the motor I4 rotates to drive the drill bit 5 to rotate, thereby drilling the workpiece. After the processing is completed, the motor I4 is turned off, and the telescopic rod of the cylinder 2 is controlled to shorten again, so that the receiving block 71 moves inward to resist the third workpiece in the storage frame 6, and then the motor II12 is turned on again, so that the rotating disk 13 continues to drive the two receiving seats 14 to rotate 180 degrees clockwise to exchange positions. During the rotation of the receiving seat 14 on the right, the gear 15 on the right and the arc rack 17 complete a rotation. The torsion spring 16 is meshed, so that the right connecting shaft 151 drives the receiving seat 14 to rotate 120 degrees, and the torsion spring 16 is deformed accordingly, so that the receiving seat 14 is tilted to pour out the processed workpiece, so as to achieve the purpose of automatic unloading. The poured workpiece falls into the collection box, and after the gear 15 on the right is disengaged from the arc-shaped rack 17, the torsion spring 16 returns to its original state, so that the right connecting shaft 151 drives the receiving seat 14 to reverse 120 degrees to a horizontal state. The staff repeats the above steps to perform batch processing on the workpieces. When the workpiece needs to be milled, the drill bit 5 can be directly replaced with a milling cutter.
