The part mounting component 4 for the A loading station is located at the front left of the system frame 1, and the unloading station mounting component is located at position D, 60 degrees to the left of the front left. The remaining B1, B2, C1, and C2 are four drilling stations: drilling the front end hole, drilling the rear end hole, countersinking the front end hole, and countersinking the rear end hole, respectively. Four sets of pressing devices 5 are installed on the system frame 1 at positions corresponding to B1, B2, C1, and C2 for rapid part pressing. The unloading robot 2 is installed at position D, forming the rapid pressing and unloading of part 9. The part mounting component 4 includes a part mounting base 10 and a part slot 12 set on the part mounting base 10. The clamping device 5 includes a hydraulic cylinder 15 and a push rod 14. The output shaft of the hydraulic cylinder 15 is connected to one end of the push rod 14, and the other end of the push rod 14 is aligned with the radially outward end port of the part slot 12 corresponding to the drilling station.

[0026] like Figure 5 and Figure 6 As shown, the feeding unit includes a feeding chute 20 and a T-shaped part conveying track 19 connected to it. A feeding cylinder 22 is installed on the right side of the feeding chute 20. The front end of its feeding push rod 21 is connected to the feeding block 18 at the feeding station 23 at position E in the middle of the feeding chute 20. The feeding push rod 21 can push it to the leftmost feeding station F. This device is installed at the front end of the system frame 1. The feeding block 18 at the leftmost feeding station F is aligned with the middle part mounting piece 4 on the part transfer turntable 3 in the middle of the system frame 1. The feeding push rod 17 of the feeding cylinder 16 is adjusted to be in a straight line with the feeding block 18 and the part mounting piece 4, and the feeding push rod 17 is positioned to push the part. Then, the part conveying track 19 is connected to the vibratory feeding device and the system device is fixed.

[0027] like Figure 7 and Figure 8As shown, the unloading unit includes an unloading cylinder 26, an unloading piston rod 25, and an unloading fork 27 mounted on the end of the unloading piston rod 25. The unloading unit is installed at the front left of the system frame 1 and consists of the unloading cylinder 26, the unloading piston rod 25, and the unloading fork 27 connected to the end of the piston rod. The unloading unit is mounted on the system frame 1, with the unloading piston rod 25 extending above the part mounting component 4 at the unloading point D on the part transfer turntable 3. This positions the unloading fork 27, located slightly behind the stop pin 11 behind the part slot 12 on the part mounting component 4, allowing the unloading fork to push the machined part 9 out of the part slot 12, thus achieving automatic unloading. A avoidance groove 28 is machined on the unloading fork 27 to prevent interference with the stop pin 11.

[0028] like Figure 9 The drilling apparatus 13 shown consists of a device column 29 mounted on a system frame 1, a vertical moving mechanism 33 mounted on the top of the device column, a crossbeam 31, and a drill bit system 32 mounted on the crossbeam. The device column 29 supports the vertical moving mechanism 33, which consists of a vertical moving cylinder 37 mounted on the top of the device column 29, a vertical moving support plate 35 connected to the upper end of the piston of the vertical moving cylinder 37, a vertical moving connecting plate 34, and the drill bit system 32 on the crossbeam 31.

[0029] Computer control and auxiliary systems are used to control the motors of various hydraulic cylinders and reducers.

[0030] The working principle and process of this fully automatic rapid drilling system are as follows: The system frame 1 is rectangular, and a turntable drive device 6 is installed inside. The turntable drive device 6 includes a reducer 7, a transmission rod 8, and a connected part-changing turntable 3. Six sets of part mounting components 4 are evenly distributed at 60 degrees on the part-changing turntable. The part mounting components 4 are machined with part slots 12 and stop pins 11 to restrict and clamp the parts, forming a part mounting device. At the top of the system frame 1, corresponding to the front and rear drilling and counterboring positions of parts B1, B2, C1, and C2 on the part-changing turntable 3, four sets of clamping devices 5 are installed. The clamping devices 5 on the system frame 1 and the part mounting components 4 on the part-changing turntable 3 work together to quickly clamp the parts. An unloading robot 2 is installed on the front left of the system frame 1, on a straight line corresponding to the unloading position D on the part-changing turntable 3, for rapid automatic unloading. A feeding unit is connected to the system frame 1. The feeding unit consists of a T-shaped structure formed by a feeding chute 20 and a parts conveying track 19. A feeding cylinder 22 is installed at the right end of the feeding chute 20. The feeding push rod 21 is adjusted. The feeding station 23 is set at position E in the middle of the feeding chute 20, which is connected to the parts conveying track 19. This station is used to receive the parts 9 to be processed from the vibrating feeder via the parts conveying track 19. A feeding station 24 is set at position A on the parts transfer turntable 3 at the leftmost end of the feeding chute 20. This station is aligned with the parts mounting component 4 on the parts transfer turntable 3. A feeding cylinder 16 is installed on the straight line corresponding to the feeding block 18 at the parts mounting component 4 and the feeding station 24. This cylinder is used to push the parts 9 to be processed from the feeding block 18 at the feeding station 24 into the parts mounting component 4 on the parts transfer turntable 3. A material unloading robot 2 is installed on the left front of the system frame 1, in a straight line with the unloading station at position D on the part transfer turntable 3. The unloading piston rod 25 of the robot passes over the part mounting part 4 at point D, so that the unloading fork 27 installed at the front end of the unloading piston rod 25 is located slightly behind the stop pin 11 behind the part slot 12, which facilitates unloading. When the unloading piston rod 25 moves, the opening of the unloading fork, i.e., the avoidance groove 28, can pass through the stop pin 11. The drilling device 13 is supported on the system frame 1 by the device column 29. This system has four sets of drilling devices 13 installed at the front and rear drilling and counterboring stations for parts B1, B2, C1, and C2. The drilling device 13 consists of a vertical moving mechanism 33, a crossbeam 31, and a drilling tool system 32. The vertical movement mechanism 33 is installed at the top of the device column 29. The vertical movement cylinder 37 is connected to the vertical movement connecting plate 34 and the support beam hinge 36 via the vertical movement support plate 35. The vertical movement mechanism 33 is used to adjust the stroke of drill bits of different lengths during processing, saving processing time. The drilling system 32 is installed on the beam 31 and processes according to computer instructions. The drilling system 32 includes a bottom drill head 30 located at one end of the beam 31.

[0031] The workflow is as follows: Adjust the feeding block 18 in the feeding chute 20 of the feeding unit on the system frame 1 to be fixed to the part mounting part 4 on the part transfer turntable 3; adjust the unloading fork 27 on the unloading robot 2 on the system frame 1 to the appropriate position of the stop pin 11 in the part slot 12 on the part mounting part 4 at the unloading station at point D; adjust the push rod 14 of the clamping device 5 on the system frame 1 to the appropriate position. Adjust the vertical movement mechanism 33 according to the age of the drill bit in the drilling system 32 to position the drill head 30 in a suitable position and set the machining program.

[0032] When the system starts, the part 9 to be processed, sent from the loading station 24, is conveyed via the part conveying track 19 to the part slot of the loading block 18 at station E on the feeding chute 20. The feeding cylinder 22 starts and pushes the loading block 18 from the loading station 23 (E) to the loading station F at the left end of the feeding chute 20 via the feeding push rod 21. At this time, the loading cylinder 16 starts and the feeding push rod 17 extends to fill the part slot in the loading block 18 at the loading station F. The part 9 to be processed is pushed into the part slot 12 of the part mounting part 4 at point A on the part transfer turntable 3. Then, the loading cylinder 16 retracts to the initial position, and the feeding cylinder 22 starts the loading and feeding block 18 to pull back to the E loading position of the feeding chute 20 to wait for the next loading. At the same time, the turntable drive device 6 starts and drives the part transfer turntable 3 to rotate 60 degrees counterclockwise, so that the part mounting part 4 at point A, after the part has been loaded, rotates to the front hole drilling position at point B1 and stops. The system starts the clamping device 5, and the push rod 14 extends from the outside to the inside to clamp the part 9 to be processed between the push rod and the stop pin 11. After the part is clamped, the drilling device 13 starts to process the front hole. The front hole is then processed. The drilling device 13 rises to the predetermined position and stops; the clamping device 5 releases and loosens the part, then the turntable drive device 6 starts, driving the part-changing turntable 3 to rotate counterclockwise by 60 degrees again. At the same time, the part A is sent to the B1 drilling front hole station, and the part with the drilled front hole is sent from the B1 station to the B2 drilling rear hole station. The above steps are repeated, and the processed part is sent to the D unloading station. At this time, the unloading robot 2 starts, the unloading cylinder 26 starts, and the unloading piston rod 25 moves from the inside to the outside. The unloading fork 27 pushes the part 9 out of the part slot 12 at D, completing the unloading. After completing the complete processing of a part, the processing operation is repeated.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
