Description

Technical Field

[0001] This utility model relates to the field of drilling technology for small connecting pressure plate parts, and in particular to a material unloading device for a drilling system. Background Technology

[0002] Currently, the production of aerospace structural components, automotive engine turbochargers, and other products requires a large number of small connecting pressure plate parts. These parts are characterized by a length of 50-80 mm and a thickness of 4-5 mm, with a connecting hole at each end and chamfered openings. The hole diameter is approximately 3-8 mm, and the chamfering ensures that the connecting screws are flush with the connecting plate. Currently, these parts are manufactured manually by drilling double-ended through holes on a special tooling, followed by manual chamfering. This method is time-consuming, labor-intensive, and involves frequent operations, easily leading to fatigue and injury. The unloading device of traditional drilling systems is not suitable for the drilling system for small connecting pressure plate parts developed by the inventor, making continuous and stable unloading of these parts impossible.

[0003] Therefore, a material unloading device for drilling systems was developed to solve the above problems. Utility Model Content

[0040] The unloading claw 2 is a rectangular plate, and the avoidance groove 28 is a strip-shaped notch on the unloading claw 2 facing downward.

[0041] The unloading claw 2 is fixed to the other end of the piston rod of the hydraulic cylinder by bolts.

[0042] The specific structure of the unloading device for a drilling system according to this utility model is as follows:

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pressing unit includes a system frame 1 and pressing devices 5 and unloading claws 2 mounted on the system frame; a turntable drive device 6 is installed inside the system frame 1, which includes a reducer 7, a transmission rod 8, a turntable 3 connected to the transmission rod 8, and part mounting components 4 mounted on the shifting turntable. Six sets of part mounting components 4 are mounted on the turntable 3 of this pressing device, distributed at 60-degree intervals. The part mounting component 4 at the A loading station is located at the front left of the system frame, 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. Unloading claws 2 are installed at positions corresponding to the D unloading station, forming a rapid part pressing and unloading system. The part mounting component 4 includes a part mounting base 10 and a part slot 12 disposed 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 position.

[0044] like Figure 5 and Figure 6As shown, the feeding unit includes a horizontally arranged feeding chute 20 and a part conveying track 19 connected to it in a T-shape. A feeding cylinder 22 is installed on the right side of the feeding chute 20. The feeding chute 20 includes a chute body and a feeding block 18 disposed on the chute body. The feeding cylinder piston 21 is aligned with and connected to the feeding block 18. The feeding block 18 is provided with a part slot in the longitudinal direction. The feeding cylinder piston 21 can push it to the leftmost F feeding station and align it with the feeding port and the part conveying track 19.

[0045] like Figure 9 The drilling apparatus 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 31. The device column 29 supports the vertical moving mechanism, which comprises 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. The drill bit system 32 includes a bottom drill bit 30 located at one end of the crossbeam 31.

[0046] Computer control and auxiliary systems are used to control the motors and reducers of each hydraulic cylinder.

[0047] 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 turntable 3. Six sets of part mounting components 4 are evenly distributed at 60 degrees on the part transposition turntable. The part mounting components 4 are machined with part slots 12 and limiting pins 11 for restricting and clamping parts, forming a part mounting device. Four sets of clamping devices 5 are installed on 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 turntable 3. The clamping devices 5 on the system frame 1 and the part mounting components 4 on the turntable 3 work together to quickly clamp the parts. An unloading claw 2 is installed on the front left of the system frame 1, on a straight line corresponding to the unloading position D on the 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 piston 21 of the feeding cylinder 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. It is used to receive the parts 9 to be processed, which are vibrated and conveyed by the vibrating feeder through the parts conveying track 19. A feeding station 24 is set at position A on the turntable 3 at the leftmost end of the feeding chute 20, which is aligned with the parts mounting part 4 on the turntable 3. A feeding cylinder 16 is installed on the straight line corresponding to the feeding block 18 at the parts mounting part 4 and the feeding station 24. It is used to push the parts 9 to be processed in the feeding block 18 at the feeding station F into the parts mounting part 4 on the turntable 3. A material unloading claw 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 turntable 3. The piston rod 25 of the manipulator's cylinder passes over the part mounting component 4 at point D, so that the unloading fork 27 installed at the front end of the piston rod 25 is positioned slightly behind the limiting pin 11 behind the part slot 12, facilitating unloading. When the piston rod 25 moves, the opening of the unloading fork 27, i.e., the avoidance groove 28, can pass through the limiting 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 positions 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.

[0048] The workflow is as follows:

[0049] 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 turntable 3, which serves as the feeding chute; adjust the unloading fork 27 on the unloading claw 2 on the system frame 1 to the appropriate position of the limiting 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 condition of the drill bit in the drilling system 32 to position the drill head 30 in a suitable position and set the machining program.

[0050] When the system starts, the part 9 to be processed, delivered from the vibratory feeding station 24, is sent through the part conveying track 19 to the part slot of the feeding block 18 at station E on the feeding chute 20. The feeding cylinder 22 starts and pushes the feeding block 18 from the feeding station 23 (E) to the feeding station F at the left end of the feeding chute 20 via the feeding cylinder piston 21. At this time, the feeding cylinder 16 starts and the feeding push rod 17 extends to push the part 9 to be processed in the feeding block 18 at the feeding station F into the part slot 12 of the part mounting part 4 at point A on the turntable 3. Then the feeding cylinder 16 returns to the initial position and the feeding cylinder 22 starts and pulls the feeding block 18 back to the feeding station E of the feeding chute 20 to wait for the next feeding. At the same time, the turntable drive device 6 starts and drives the 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 drilling station at the front hole at point B1 and stops. The system activates the clamping device 5, and the push rod 14 extends from the outside in, clamping the part 9 to be processed between the push rod and the limiting pin 11. After the part is clamped, the drilling device 13 starts to process the front end hole. The front end hole is processed. The drilling device 13 rises to the predetermined position and stops; the clamping device 5 releases and loosens the part, and then the turntable drive device 6 starts, driving the turntable 3 to rotate counterclockwise 60 degrees again. At the same time, the part loaded at A is sent to the B1 front end hole drilling station, and the part with the drilled front end hole is sent from the B1 station to the B2 rear end hole drilling station. The above steps are repeated, and the processed part is sent to the D unloading station. At this time, the unloading claw 2 starts, the unloading cylinder 26 starts, and the cylinder 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 processing of one part, the processing operation is repeated.

[0051] 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.
