Automated drilling equipment can reduce manual intervention and improve production efficiency and quality stability. The performance and reliability of instruments are closely related to the drilling quality of their internal metal parts. High-quality drilling equipment can ensure dimensional accuracy, surface roughness, position accuracy, etc. of the drilling, and improve the overall quality and stability of the instruments.

[0014] The present invention provides a metal part drilling device for instrument manufacturing. It has the following beneficial effects:

[0015] 1. For the metal part drilling device for instrument manufacturing, an electric screw is provided. The rotating part of the electric screw drives the hollow worm gear to rotate. The rotation of the hollow worm gear drives the support plate to rotate. The rotation of the support plate drives the support device to rotate. The rotation of the support device drives the housing to rotate. The rotation of the secondary collection groove drives the outer shell to rotate, so as to drill holes at different positions of the outer shell. And due to the cooperation of the hollow worm gear and the electric screw, the hollow worm gear is in a stable state and not easy to move. The fixed shaft supports the support plate, the support bracket supports the fixed shaft, and the air extraction device extracts the air inside the support device, so that the debris from drilling falls inside the support device under the driving action of the air, thus preventing the debris from flying around. And the flow of air drives the air flow at the drilling position, so as to cool the drilling position, thus preventing thermal deformation due to overheating during drilling, and improving the product quality.

[0016] 2. The metal part drilling equipment for instrument manufacturing is provided with a sliding sleeve. The rotation of the sliding sleeve drives the rotation of the connecting disc, the rotation of the connecting disc drives the rotation of the adjustment disc, and the rotation of the adjustment disc drives the sliding rotating shaft to slide along the inner wall of the arc-shaped chute. The sliding of the sliding rotating shaft along the inner wall of the arc-shaped chute causes the sliding rotating shaft to approach the rotation center of the fixed shaft, and the sliding rotating shaft drives the support frame to move. The support frame slides along the chute starting from the side of the support plate and the adjustment disc, thereby reducing the distance between multiple support frames, so as to adapt to the installation of shells with different diameter sizes. When the shell is installed, the first spring rebounds under the pulling force at the beginning, thereby driving the sliding sleeve to approach the fixed disc, making the slot on the side of the sliding sleeve cooperate with the braking rack, thereby performing braking, fixing the relative position between the adjustment disc and the connecting disc, thus fixing the position of the sliding rotating shaft relative to the rotation center of the fixed shaft, maintaining the size of the adapted shell and forming a self-locking mechanism under the cooperation of the fixed disc and the connecting disc, and transmitting the reaction force against the shell to the side of the braking rack. The braking rack is at a specific angle, so that it is easy to adjust when pulling the sliding sleeve away from the fixed disc. At the same time, the sliding sleeve approaches the fixed disc under the driving of the first spring, so that the connecting disc and the fixed disc are in a braking state and do not loosen during processing. The movement of the sliding rotating shaft drives the support frame to move, the support frame moves along the first slide bar, the movement of the support frame drives the connecting component to move, and the movement of the connecting component drives the contact component to move, thereby reducing or expanding the distance between the contact components, so as to install shells with different diameter sizes. The main collection groove and the secondary collection groove slide relative to each other and are automatically telescoped by the first spring rod, so as to adapt to the installation of shells with different internal structures. The debris generated during drilling directly falls into the main collection groove and the secondary collection groove, thereby cleaning the drilling debris. It realizes the installation and positioning of shells with different sizes, and through the self-locking mechanism, the shell is kept in a stable state during processing, which is convenient for processing. At the same time, it supports the inside of the shell, reduces the deformation of the shell caused by the pressure of the drill bit during drilling, and collects the drilling debris to avoid the flying of debris.

[0017] 3. The metal part drilling equipment for instrument manufacturing is provided with a contact housing. The contact housing drives the second slide bar to move upward, so that the second slide bar slides inside the first slide groove, thereby reducing the distance between the contact housings, and then adapting to slide bars of different diameter sizes. After moving to the appropriate position, under the attraction of the bar magnet, the second slide bar is driven to engage with the first rack to fix the position of the contact housing. When drilling holes at the positions between multiple groups of contact housings, uniform support is provided for the two suspended sides during drilling, thereby reducing the deformation of the housing during drilling. When installing the housing, the top of the contact rubber block directly contacts the inner wall of the housing. The contact between the contact rubber block and the inner wall of the housing drives the contact slider to move. The movement of the contact slider generates a positive pressure on the spring piece, so that the reaction force of the spring piece is fed back to the contact slider, thereby making the contact rubber block closely adhere to the inner wall of the housing, increasing the friction with the inner wall of the housing, and thus keeping the housing stable during drilling. The suspended debris falls under the action of gravity. Start the electric air pump. The electric air pump extracts air. The electric air pump drives the air to enter the polygon pipeline along the side of the filter screen, along the inner wall of the rotating cylinder, along the rigid air pipe, and enters the interior of the electric air pump through the first air pipe. When the air flows inside the rotating cylinder, it drives the pneumatic fan blade to rotate, thereby driving the rotating cylinder to rotate along the surface of the rigid air pipe. This not only realizes the extraction of air and the cooling of the drilling position, but also the filter screen rotates to prevent debris from accumulating at the same position and causing air blockage, thus prolonging the service life.

[0018] 4. The metal part drilling equipment for instrument manufacturing is provided with a sliding ring moving upward. The movement of the sliding ring drives the connecting rod to move along the sliding hole under the action of the rotating shaft. The connecting rod drives the movable end of the second spring rod to contract. The contraction of the second spring rod drives the drill bit brake strip to move, so that the drill bit brake strip releases the control of the drill bit. After the drill bit is replaced, the drill bit is inserted into the drill bit fixing cylinder, and the sliding ring is moved downward, so that the movable end of the second spring rod moves under the action of the spring inside the second spring rod, thereby driving the drill bit brake strip to move. The movement of the drill bit brake strip fixes the side of the drill bit, thus completing the replacement of the drill bit. And due to the shape setting of the sliding hole, the connecting rod is fixed at a fixed position in the horizontal direction relative to the side of the sliding hole, thereby preventing the drill bit from loosening during drilling. The cooperation between the second slide groove and the third slide bar fixes the sliding position, thereby determining the sliding trajectory in the vertical direction, improving the speed of replacing the drill bit compared with the traditional method of screwing with threads, and thus facilitating the adjustment of the drilling size.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 2, the present invention provides a technical solution: a metal part drilling device for instrument manufacturing, including a bottom plate bracket 1. The top of the bottom plate bracket 1 is fixedly connected to a support bottom plate 2. The top of the support bottom plate 2 is fixedly connected to the fixed end of a first electric sliding table 3. The side of the moving end of the first electric sliding table 3 is fixedly connected to the fixed end of a second electric sliding table 4. The top of the moving end of the second electric sliding table 4 is fixedly connected to a fixing device 5. The top of the first electric sliding table 3 is fixedly connected to the fixed end of an electric lifter 6. The side of the moving end of the electric lifter 6 is fixedly connected to a drilling motor 8. A quick-release component 7 is fixedly connected to the driving shaft of the drilling motor 8. The electric lifter 6 is arranged on one side of the second electric sliding table 4, and the quick-release component 7 is arranged above the fixing device 5.

[0032] The bottom plate bracket 1 and the support bottom plate 2 support the device as a whole. The first electric sliding table 3 and the second electric sliding table 4 cooperate to drive the fixing device 5 to move to different positions. The electric lifter 6 drives the drilling motor 8 to move up and down. The drilling motor 8 drives the quick-release component 7 to move. The quick-release component 7 quickly disassembles and installs drills of different models, so as to meet different processing scenarios. The fixing device 5 fixes the circular shell to be drilled, adjusts and positions it between different sizes, and rotates at different angles through a specific device. At the same time, it supports the inner wall of the shell during drilling, so as to prevent the shell from deforming due to pressure during drilling and improve the qualified rate.

[0033] The fixing device 5 includes a fixing bracket 501. The top of the fixing bracket 501 is fixedly connected to the fixed end of an electric screw 502. A hollow worm wheel 503 is engaged with the side of the rotating part of the electric screw 502. A support plate 504 is fixedly connected to the side of the hollow worm wheel 503. The side of the support plate 504 penetrates and is fixedly connected to a fixing shaft 505. A support bracket 506 is rotatably connected to the side of the fixing shaft 505. The bottom of the support bracket 506 is fixedly connected to the top of the fixing bracket 501. An adjustment component 507 is sleeved and rotatably connected to the side of the fixing shaft 505. A support device 508 is slidably connected to the side of the support plate 504.

The side of the fixing bracket 501 is fixedly connected to the top of the moving end of the second electric sliding table 4.

[0034] When drilling, the electric screw 502 is started. The rotating part of the electric screw 502 drives the hollow worm wheel 503 to rotate. The rotation of the hollow worm wheel 503 drives the support plate 504 to rotate. The rotation of the support plate 504 drives the support device 508 to rotate. The rotation of the support device 508 drives the housing to rotate. The rotation of the secondary collection groove 5085 drives the outer shell to rotate, so as to drill holes in different positions of the outer shell. And due to the cooperation of the hollow worm wheel 503 and the electric screw 502, the hollow worm wheel 503 is in a stable state and not prone to movement. The fixed shaft 505 supports the support plate 504, the support bracket 506 supports the fixed shaft 505, and the air extraction device 509 extracts the air inside the support device 508, so that the debris from drilling falls inside the support device 508 under the driving action of the air, thereby preventing the debris from flying around. And the flow of the air drives the flow of the air at the drilling position, so as to cool the drilling position, thereby preventing thermal deformation due to overheating during drilling, and thus improving the product quality.

[0035] Please refer to Figure 1 - Figure 4 As shown in the figure, the present invention provides a technical solution: the adjustment component 507 includes a sliding sleeve 5071. A connection disk 5072 is fixedly connected to the side surface of the sliding sleeve 5071. A first spring 5073 is fixedly connected to the side surface of the inner wall of the sliding sleeve 5071. One end of the first spring 5073 away from the sliding sleeve 5071 is fixedly connected to a fixed disk 5074. A braking rack 5075 is fixedly connected to the side surface of the fixed disk 5074. A slot adapted to the braking rack 5075 is opened on the side surface of the connection disk 5072. An adjustment disk 5076 is fixedly connected to the side surface of the fixed disk 5074. An arc-shaped sliding groove 5077 is opened on the side surface of the adjustment disk 5076. The sliding sleeve 5071 is sleeved on the side surface of the fixed shaft 505 and is rotatably connected to the fixed shaft 505. The fixed shaft 505 is fixedly connected to the side surface of the fixed disk 5074.

[0036] The support device 508 includes a support frame 5081. A connection component 5082 is fixedly connected to the side of the support frame 5081. A contact component 5083 is fixedly connected to the side of the connection component 5082. A main collection groove 5084 is fixedly connected to the side of the support frame 5081 at a position below the contact component 5083. A secondary collection groove 5085 is slidably connected to the inner wall of the main collection groove 5084. A fixed end of a first spring rod 5086 is fixedly connected to the side of the support frame 5081 at a position below the main collection groove 5084. A movable end of the first spring rod 5086 is fixedly connected to the bottom of the secondary collection groove 5085 through a bracket. A first slide bar 5087 passes through and is slidably connected to the bottom of the support frame 5081. An air pipe through hole 5088 adapted to the main collection groove 5084 is formed in the side of the support frame 5081. A sliding rotating shaft 5089 is fixedly connected to a side of the support frame 5081 away from the connection component 5082. An arc-shaped chute adapted to the support frame 5081 is formed in the side of the support plate 504. The sliding rotating shaft 5089 extends into the interior of the arc-shaped chute 5077 and is slidably connected to the inner wall of the arc-shaped chute 5077. A chute adapted to the support frame 5081 is formed in the side of the adjustment disc 5076. A side of the first slide bar 5087 is fixedly connected to the side of the support plate 504.

[0037] During the installation of the outer shell, manually pull out and rotate the sliding sleeve 5071. The rotation of the sliding sleeve 5071 drives the rotation of the connecting plate 5072. The rotation of the connecting plate 5072 drives the rotation of the adjustment plate 5076. The rotation of the adjustment plate 5076 drives the sliding shaft 5089 to slide along the inner wall of the arc-shaped chute 5077. The sliding of the sliding shaft 5089 along the inner wall of the arc-shaped chute 5077 causes the sliding shaft 5089 to move closer to the rotation center of the fixed shaft 505. The sliding shaft 5089 drives the support frame 5081 to move. The support frame 5081 slides along the chute starting from the side of the support plate 504 and the adjustment plate 5076, thereby reducing the distance between multiple support frames 5081, so as to adapt to the installation of outer shells with different diameter sizes. When the outer shell is installed, the first spring 5073 rebounds under the pulling force at the beginning, thereby driving the sliding sleeve 5071 closer to the fixed disk 5074, making the slot on the side of the sliding sleeve 5071 cooperate with the braking rack 5075, thereby performing braking, fixing the relative position between the adjustment plate 5076 and the connecting plate 5072, thereby fixing the position of the sliding shaft 5089 relative to the rotation center of the fixed shaft 505, thus maintaining the size of the adapted outer shell and forming a self-locking mechanism under the combined action of the fixed disk 5074 and the connecting plate 5072, and the reaction force against the outer shell is transmitted to the side of the braking rack 5075. The braking rack 5075 is at a specific angle, so that it is easy to adjust when pulling the sliding sleeve 5071 away from the fixed disk 5074. At the same time, the sliding sleeve 5071 approaches the fixed disk 5074 under the driving action of the first spring 5073, so that the connecting plate 5072 and the fixed disk 5074 remain in a braking state and do not loosen during processing. The movement of the sliding shaft 5089 drives the support frame 5081 to move. The support frame 5081 moves and slides along the first slide bar 5087. The movement of the support frame 5081 drives the connecting component 5082 to move. The movement of the connecting component 5082 drives the contact component 5083 to move, thereby reducing or expanding the distance between the contact components 5083, so as to install outer shells with different diameter sizes. The main collection groove 5084 and the secondary collection groove 5085 slide relative to each other and are automatically telescoped through the first spring rod 5086, so as to adapt to the installation of outer shells with different internal structures. The debris generated during drilling directly falls into the main collection groove 5084 and the secondary collection groove 5085, thereby cleaning the drilling debris. The installation and positioning of outer shells of different sizes are realized, and the outer shell is kept in a stable state during processing through a self-locking mechanism, which is convenient for processing. At the same time, the inside of the outer shell is supported to reduce the deformation of the outer shell caused by the pressure of the drill bit during drilling. At the same time, the drilling debris is collected to avoid the flying of debris.

[0039] The contact component 5083 includes a contact housing 50831, a spring piece 50832 is fixedly connected to the bottom of the inner wall of the contact housing 50831, a contact slider 50833 is fixedly connected to the top of the spring piece 50832, a contact rubber block 50834 is fixedly connected to the top of the contact slider 50833, and the side of the contact housing 50831 is fixedly connected to the side of the second slide bar 50825.

[0040] The air extraction device 509 includes an electric air pump 5091, a first air pipe 5092 is connected to the top of the electric air pump 5091, a polygonal pipe 5093 is connected to the side of the first air pipe 5092, a rigid air pipe 5094 is connected to the side of the polygonal pipe 5093, a rotating cylinder 5095 is rotatably connected to the side of the rigid air pipe 5094, a filter screen 5096 is fixedly connected to the top of the rotating cylinder 5095, a pneumatic fan blade 5097 is fixedly connected to the inner wall of the filter screen 5096, the filter screen 5096 is arranged on the inner wall of the main collection tank 5084, the rigid air pipe 5094 passes through the air pipe through hole 5088 and is fixedly connected to the support frame 5081, and the side of the electric air pump 5091 is fixedly connected to the side of the fixed bracket 501.

[0041] When installing the outer shell, manually move the contact outer shell 50831. The contact outer shell 50831 drives the second slide bar 50825 to move upward, so that the second slide bar 50825 slides inside the first chute 50822, thereby reducing the distance between the contact outer shells 50831, and then adapting to slide bars of different diameter sizes. After moving to the appropriate position, under the attraction of the bar magnet 50824, the second slide bar 50825 is driven to engage with the first rack 50823 to fix the position of the contact outer shell 50831. When drilling holes at the positions between multiple groups of contact outer shells 50831, uniform support is provided for the two suspended sides during drilling, thereby reducing the deformation of the outer shell during drilling. When installing the outer shell, the top of the contact rubber block 50834 directly contacts the inner wall of the outer shell. The contact between the contact rubber block 50834 and the inner wall of the outer shell drives the contact slider 50833 to move. The movement of the contact slider 50833 generates a positive pressure on the spring piece 50832, so that the reaction force of the spring piece 50832 is fed back to the contact slider 50833, thereby making the contact rubber block 50834 closely adhere to the inner wall of the outer shell, increasing the friction with the inner wall of the outer shell, and keeping the outer shell stable during drilling. The suspended debris falls under the action of gravity. Start the electric air pump 5091. The electric air pump 5091 extracts air. The electric air pump 5091 drives the air to enter the polygonal pipeline 5093 along the side of the filter screen 5096, along the inner wall of the rotating cylinder 5095, through the hard air pipe 5094, and enters the interior of the electric air pump 5091 through the first air pipe 5092. When the air flows inside the rotating cylinder 5095, it drives the pneumatic fan blade 5097 to rotate, thereby driving the rotating cylinder 5095 to rotate along the surface of the hard air pipe 5094. This not only realizes the extraction of air and the cooling of the drilling position, but also rotates the filter screen 5096 to prevent debris from accumulating at the same position, resulting in blocked air flow, thereby extending the service life.

[0042] Please refer to Figure 1 - Figure 10, the present invention provides a technical solution: The quick-release component 7 includes a sliding ring 701, a sliding hole 702 is formed on the side surface of the sliding ring 701, a connecting rod 703 is rotatably connected to the inner wall of the sliding hole 702 through a rotating shaft, and one end of the connecting rod 703 away from the sliding ring 701 is rotatably connected to the movable end of a second spring rod 704 through a rotating shaft. The fixed end side of the second spring rod 704 is fixedly connected to a drill bit fixing cylinder 705, a second sliding groove 706 is fixedly connected to the side surface of the drill bit fixing cylinder 705, a third sliding strip 707 is slidably connected to the side surface of the second sliding groove 706, the movable end of the second spring rod 704 is fixedly connected to a drill bit braking strip 708, the movable end of the second spring rod 704 penetrates through the side surface of the drill bit fixing cylinder 705 and is slidably connected to the side surface of the drill bit fixing cylinder 705, and the top of the drill bit fixing cylinder 705 is fixedly connected to the side surface of the driving shaft of the drilling motor 8.

[0043] When installing the drill bit, manually drive the sliding ring 701 to move upward. The movement of the sliding ring 701 drives the connecting rod 703 to move along the sliding hole 702 under the action of the rotating shaft. The connecting rod 703 drives the movable end of the second spring rod 704 to contract. The contraction of the second spring rod 704 drives the drill bit braking strip 708 to move, so that the drill bit braking strip 708 releases the control of the drill bit. When the drill bit is replaced, insert the drill bit into the drill bit fixing cylinder 705 and move the sliding ring 701 downward. Thus, the movable end of the second spring rod 704 moves under the action of the spring inside the second spring rod 704, driving the drill bit braking strip 708 to move. The movement of the drill bit braking strip 708 fixes the side surface of the drill bit, completing the replacement of the drill bit. And because of the shape setting of the sliding hole 702, the connecting rod 703 is fixed at a fixed position in the horizontal direction relative to the side surface of the sliding hole 702, preventing the drill bit from loosening during drilling. The cooperation between the second sliding groove 706 and the third sliding strip 707 fixes the sliding position, determining the sliding trajectory in the vertical direction, improving the speed of replacing the drill bit compared with the traditional method of screwing with threads, thus facilitating the adjustment of the drilling size.
