Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1-Figure 8 A positioning drilling device for aluminum alloy door and window production includes a base 1, a column 2, an operating table 3 and a lifting output rod 4.

It also includes: The clamping assembly 5 is located on the top of the placement platform 101 , and is used to fix the door and window parts on the top of the placement platform 101 .

[0028] The shielding component 6 is located on the outer wall of the lifting output rod 4, and is used to block iron filings generated during the drilling process.

[0029] The clamping assembly 5 includes a bent rod 501, an outer shell 502, a frame 503, a fixed rod 504, a splint 505, a telescopic rod 506, and a pushing plate 507. The bent rod 501 is fixedly connected to the outer wall of the lifting output rod 4, the outer shell 502 is arranged above the placement table 101, the frame 503 is arranged above the placement table 101, the fixed rod 504 is fixedly connected to the top of the placement table 101, the splint 505 is arranged at the top of the placement table 101, the telescopic rod 506 is arranged inside the outer shell 502, and the pushing plate 507 is located inside the outer shell 502.

[0030] It should be noted that: the bottom end of the bent rod 501 penetrates the shell 502 and extends to the inside of the shell 502, the outer wall of the bent rod 501 is slidably connected to the inner wall of the shell 502, the bent rod 501 can slide inside the shell 502 and compress the air inside the shell 502 at the same time, one end of the shell 502 penetrates the frame 503 and extends to the outside of the frame 503 and is fixedly connected to the frame 503, the top end of the fixed rod 504 is fixedly connected to the bottom of the frame 503, and the fixed rod 504 can pass through the frame 503 to the shell 502 is supported, the bottom of the splint 505 is slidably connected to the top of the placement table 101, one end of the telescopic rod 506 passes through the inner wall of the shell 502 and is fixedly connected to the outer wall of the splint 505, the outer wall of the pushing plate 507 is slidably connected to the inner wall of the shell 502, and is fixedly connected to one end of the telescopic rod 506. When the gas inside the shell 502 is compressed by the bent rod 501, the compressed air will push the splint 505 to move on the top of the placement table 101 through the pushing plate 507 and the telescopic rod 506, and clamp the door and window parts.

[0031] By arranging a bent rod 501 and a clamping plate 505 on the outer wall of the lifting output rod 4 and the top of the placement platform 101, and by lowering the height of the lifting output rod 4, the bent rod 501 can slide inside the outer shell 502 and squeeze the air inside the outer shell 502 to increase the air pressure. At this time, the compressed air will push the clamping plate 505 through the pushing plate 507 and the telescopic rod 506 to clamp and fix the aluminum alloy door and window parts placed on the top of the placement platform 101. Since the position of the clamping plate 505 can be adjusted, the clamping plate 505 can clamp and fix door and window parts of different sizes, thereby solving the problem that the existing drilling device cannot effectively clamp and fix door and window parts of different sizes.

[0032] The door and window parts that need to be drilled are placed on the top of the placement table 101, and the operation of the lifting output rod 4 is controlled so that the lifting output rod 4 drives the drill bit 401 to descend. At this time, the bending rod 501 will slide inside the shell 502 under the action of the lifting output rod 4, and compress the air inside the shell 502. After the air is compressed, the internal pressure increases. In order to restore the air pressure, the compressed air will push the push plate 507 to move, so that the push plate 507 drives the splint 505 to move through the telescopic rod 506 until the outer wall of the splint 505 abuts against the outer wall of the door and window parts, thereby completing the fixation of the door and window parts.

[0033] The telescopic rod 506 includes a shell 5061, a connecting rod 5062, a compression plate 5063, a spring 5064 and a pipe 5065. The shell 5061 is located inside the outer shell 502, the connecting rod 5062 is located inside the outer shell 502, the compression plate 5063 is slidably connected to the inside of the shell 5061, the spring 5064 is fixedly connected to the inner wall of the shell 5061, and the pipe 5065 is fixedly connected to the top of the shell 5061.

[0034] It should be noted that: one end of the shell 5061 passes through the shell 502 and is slidably connected to the inner wall of the shell 502, the end of the shell 5061 extending to the outside of the shell 502 is fixedly connected to the outer wall of the clamping plate 505, one end of the connecting rod 5062 is fixedly connected to the outer wall of the pushing plate 507, the end of the connecting rod 5062 away from the pushing plate 507 passes through the shell 5061 and extends to the inside of the shell 5061, and is slidably connected to the inner wall of the shell 5061 that is penetrated, and the end of the connecting rod 5062 extending to the inside of the shell 5061 is fixedly connected to the outer wall of the compression plate 5063. When the compressed air inside the shell 502 pushes the pushing plate 507 to move, the pushing plate 507 is pushed into the outer wall of the compression plate 5063. The movable plate 507 will push the connecting rod 5062, so that the connecting rod 5062 pushes the compression plate 5063 to move inside the shell 5061 and compress the air inside the shell 5061. The spring 1 5064 is fixedly connected to the outer wall of the compression plate 5063 on the side away from the shell 5061. The existence of the spring 1 5064 can push the compression plate 5063 to reset. The pipe 5065 is connected to the interior of the shell 5061. The output end of the pipe 5065 is located at the top of the outer wall of the clamp 505. The compressed air inside the shell 5061 will be discharged through the pipe 5065 and clean the surface of the door and window parts placed on the top of the placement table 101.

[0035] By arranging a compression plate 5063 and a pipe 5065 inside the outer shell 502, when the outer wall of the splint 505 contacts the surface of the door and window parts, the bent rod 501 continues to press downward, and the compressed air will move by pushing the push plate 507, so that the connecting rod 5062 pushes the compression plate 5063 to slide on the inner wall of the shell 5061, and compresses the gas inside the shell 5061. Since the air outlet of the pipe 5065 is located at the top of the outer wall of the splint 505, the compressed air will be discharged through the pipe 5065 and accelerate the air flow speed on the surface of the door and window parts, thereby cleaning the surface of the door and window parts and preventing the floating dust on the surface of the parts from affecting the drilling operation of the drill bit 401 on the door and window parts.

[0036] When the outer wall of the splint 505 abuts against the outer wall of the door and window parts, the bent rod 501 continues to press down. At this time, the pushing plate 507 will push the compression plate 5063 to slide inside the shell 5061 through the connecting rod 5062, and compress the air inside the shell 5061. The compressed air will be discharged through the pipe 5065 and clean the floating dust adsorbed on the surface of the door and window parts.

[0037] The shielding assembly 6 includes a top ring 601, a bottom plate 602, a second spring 603 and a movable plate 604. The top ring 601 is fixedly connected to the outer wall of the lifting output rod 4, the bottom plate 602 is located on the outer wall of the lifting output rod 4, the second spring 603 is fixedly connected to the top of the bottom plate 602, and the movable plate 604 is installed on the outer wall of the bottom plate 602.

[0038] It should be noted that: the inner wall of the bottom plate 602 is slidably connected to the outer wall of the lifting output rod 4, the bottom plate 602 can slide on the outer wall of the lifting output rod 4, the top of the spring 2 603 is fixedly connected to the bottom of the top ring 601, the existence of the spring 2 603 can push the bottom plate 602 to reset, the movable plate 604 passes through the bottom plate 602, and is slidably connected to the inner wall of the bottom plate 602, the existence of the movable plate 604 can cooperate with the splint 505 to seal the drill bit 401 to prevent iron filings from splashing.

[0039] By arranging a bottom plate 602 and a movable plate 604 on the surface of the lifting output rod 4, when the lifting output rod 4 descends, the bottom plate 602 will be driven to descend until the bottom of the bottom plate 602 contacts the top of the clamping plate 505, and at the same time, the outer wall of the movable plate 604 contacts the outer wall of the placement table 101 and the surface of the door and window parts. At this time, the movable plate 604 cooperates with the clamping plate 505 to seal the drill bit 401. At this time, when the drill bit 401 drills holes in the door and window parts, the generated debris will be blocked by the clamping plate 505 and the movable plate 604 and accumulated on the surface of the placement table 101, thereby avoiding the occurrence of iron filings splashing during the drilling process of the door and window parts.

[0040] When the lifting output rod 4 descends, it will drive the base plate 602 to move. When the bottom of the base plate 602 contacts the top of the clamping plate 505, the base plate 602 stops descending. At the same time, the bottom of the movable plate 604 contacts the top of the placement table 101 and the surface of the door and window parts, and cooperates with the clamping plate 505 to close the drill bit 401. At this time, the drill bit 401 can be started to drill holes in the aluminum alloy door and window parts.
