[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a drilling device for processing a pump impeller, comprising a workbench 1, a shell 2 is fixedly connected to the top of the workbench 1, a cylinder 3 is fixedly connected to the middle side of the shell 2, a disassembly component is provided at the output end of the cylinder 3, a drill bit 4 is provided at the bottom of the disassembly component, slide grooves 5 are provided on all sides of the top of the workbench 1, a support rod 6 is fixedly connected to the inside of the slide groove 5, a clamping plate 7 is slidably connected to the outside of the support rod 6, a rotating shaft 8 is fixedly connected to the bottom of the clamping plate 7, a disc 9 is rotatably connected to the bottom of the workbench 1, an eccentric shaft 10 is fixedly connected to the outside of the disc 9, a connecting rod 11 is provided between the rotating shaft 8 and the eccentric shaft 10, a support block 12 is fixedly connected to the inner wall of the workbench 1, and a driving component is provided on the outside of the support block 12.
[0031] Specifically, the impeller is first placed on the top of the workbench 1, and then the internal driving component is started to drive the splint 7 to pass through the slide groove 5 on the top of the workbench 1. At this time, the splint 7 passes through the internal support rod 6 of the slide groove 5 and slides outside it. As a result, the splint 7 on the top of the workbench 1 continues to shrink. At the same time, the bottom of the splint 7 drives the disc 9 to rotate through the rotating shaft 8, the connecting rod 11 and the eccentric shaft 10. At this time, the four splints 7 shrink at the same time to clamp the impeller. The eccentric shaft 10 drives the connecting rod 11, and the connecting rod 11 connects the rotating shaft 8 and the eccentric shaft 10. The outer casing 2 protects the internal parts. The cylinder 3 drives the drill bit 4 to work, and the drill bit 4 processes the impeller.
[0032] Reference Figure 1 , Figure 3 and Figure 4 The disassembly assembly includes a fixed block 15, the top of the fixed block 15 is fixedly connected to the bottom of the drill bit 4, a support ring 16 is slidably connected to one side of the fixed block 15, and a sliding block 18 is slidably connected to the other side of the fixed block 15. A spring 17 is arranged between the support ring 16 and the sliding block 18, and blocks 19 are fixedly connected to both sides of the inside of the sliding block 18. Both sides of the outside of the sliding block 18 are fixedly connected to shift blocks 20. Both sides of the outside of the fixed block 15 are provided with shifting grooves, and the outside of the shifting block 20 is slidably connected to the inside of the shifting groove. One end of the spring 17 is fixedly connected to the top of the support ring 16, and the other end of the spring 17 is fixedly connected to the bottom of the sliding block 18.
[0033] Specifically, when replacing the drill bit 4 by disassembling the assembly, first push the shift block 20 downward, so that the sliding block 18 moves downward, allowing the fixed block 15 to rotate. The fixed block 15 is rotated to make the insertion rod at the top of the drill bit 4 move from one end inside the sliding block 18 to the other end, and the fixed block 15 can be removed, so that the drill bit 4 is removed, which facilitates the replacement of the drill bit 4. Then, the replaced drill bit 4 is installed, and the insertion rod at the top of the drill bit 4 is installed against the end without the stopper 19 inside the sliding block 18. After installation to the top, push the shift block 20 downward, and then rotate the fixed block 15 to make the insertion rod at the top of the drill bit 4 move to the end with the stopper 19 inside the sliding block 18. Then, release the shift block 20, and the spring 17 releases the tension to move the sliding block 18 upward, thereby fixing the drill bit 4 through the stopper 19, and the installation is completed.
[0034] Reference Figure 1 - Figure 3The driving assembly includes a cylinder 2 13, one end of which is fixedly connected to the outside of the support block 12, a push plate 14 is fixedly connected to the output end of the cylinder 2 13, the top of the push plate 14 is fixedly connected to the bottom of one of the clamping plates 7, the top of the drill bit 4 is fixedly connected to a plug rod, the plug rod is arranged inside the sliding block 18, the sliding bottom of the clamping plate 7 is slidably connected inside the slide groove 5, one end of the connecting rod 11 is rotatably connected to the outside of the rotating shaft 8, and the other end of the connecting rod 11 is rotatably connected to the outside of the eccentric shaft 10.
[0035] Specifically, the cooperation among the support block 12, the second cylinder 13 and the push plate 14 drives the clamping plate 7 to slide inside the slide groove 5 and thus clamp the impeller. The insertion rod at the top of the drill bit 4 cooperates with other parts to facilitate the replacement of the drill bit 4. When the second cylinder 13 drives one of the clamping plates 7, the cooperation among the rotating shaft 8, the eccentric shaft 10 and the connecting rod 11 drives the remaining three clamping plates 7.
[0036] Working principle: First, start the cylinder 2 13 inside the workbench 1. The output end of the cylinder 2 13 drives the push plate 14, so that the push plate 14 drives the clamping plate 7 through the top slide 5 of the workbench 1. At this time, the clamping plate 7 passes through the internal support rod 6 of the slide 5 and slides outside it. Then the clamping plate 7 on the top of the workbench 1 continues to shrink. At the same time, the bottom of the clamping plate 7 drives the disc 9 to rotate through the rotating shaft 8, the connecting rod 11 and the eccentric shaft 10. At this time, the four clamping plates 7 shrink at the same time to clamp the impeller. Then, start the cylinder 1 3 to drive the drill bit 4 for processing. When the drill bit 4 needs to be replaced, first push the block 20 downward to move the sliding block 18 downward, so that the fixed block 15 can be rotated. The fixed block 15 is rotated to make the insertion rod at the top of the drill bit 4 move from one end inside the sliding block 18 to the other end, and the fixed block 15 can be removed, so that the drill bit 4 is removed. When installing the drill bit 4, the insertion rod at the top of the drill bit 4 is first installed against the end of the sliding block 18 without the stopper 19. After installation to the top, the shifting block 20 is pushed downward, and the fixed block 15 is rotated again to make the insertion rod at the top of the drill bit 4 move to the end of the sliding block 18 with the stopper 19, and then the shifting block 20 is released. The spring 17 releases the tension to move the sliding block 18 upward, so that the drill bit 4 is fixed by the stopper 19, and the installation is completed.
