Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically a hardware processing drilling device with self-cleaning function. Background Technology

[0002] Hardware refers to tools made from metals such as gold, silver, copper, iron, and tin through processing and casting. Drilling is often required during the processing of hardware.

[0003] A Chinese patent with publication number CN117798397A discloses a drilling device for precision hardware processing, including an adjustment mechanism and a fixing mechanism. The adjustment mechanism includes a support leg, a first sliding groove, a first threaded rotating rod, a third sliding groove, a third threaded rotating rod, and a fixing plate. The support leg is fixedly connected to the operating table, the operating table is fixedly connected to the support plate, the support plate is fixedly connected to the connecting plate, the first sliding groove is fixedly connected to the operating table, and the first sliding groove is slidably connected to the first slider. The first threaded rotating rod is rotatably connected to the first sliding groove. In use, the position of the third slider is fixed by tightening the third fixing knob to ensure accurate drill bit positioning. The drill bit is rotated by turning on the motor, and the drill bit is drilled by extending the electro-hydraulic push rod. The device is easy to operate and the drilling position is accurate.

[0004] Because drilling of hardware parts generates a large amount of metal shavings, the aforementioned drilling devices for hardware processing lack a self-cleaning mechanism and cannot clean and collect dust and shavings in a timely manner. These shavings accumulate at the drilling location or on the worktable, interfering with subsequent drilling operations, leading to decreased drilling accuracy, reduced processing quality, and easy metal shavings splashing, causing injury to the operator's eyes and skin, and increasing the risk of operator injury. Therefore, a hardware processing drilling device with a self-cleaning function is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a hardware processing drilling device with self-cleaning function.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The hardware processing drilling device with self-cleaning function of this utility model includes a base, on which a support frame is fixedly connected. Two limiting grooves are opened on the top side of the base, and two sliders are slidably assembled in each limiting groove. The top ends of the two sliders at the same end are fitted with semi-enclosed bodies. Semi-circular holes are opened on the two semi-enclosed bodies. First pneumatic cylinders are installed on the bottom ends of both sides of the support frame. First pneumatic rods are assembled on the working ends of the two first pneumatic cylinders, and the ends of the first pneumatic rods are fixed to the semi-enclosed bodies. Dust collection boxes are installed on the top two sides of the support frame. Dust collection boxes are connected to the corresponding semi-enclosed bodies by suction hoses. Negative pressure pumps are installed on the two dust collection boxes. The input port of the negative pressure pump is connected to a suction pipe, and the output port of the negative pressure pump is connected to an exhaust pipe. Before drilling, the synchronous operation of the two first pneumatic cylinders is controlled by the control panel. With the cooperation of the limiting slide and the slider, the two half-covers are brought closer together until they are in contact, thus covering the placement table and the clamped hardware. This allows for the complete containment of metal debris generated during drilling within the cover, effectively preventing debris from splashing out of the work area and facilitating subsequent collection. During drilling, the control panel controls the synchronous operation of two negative pressure pumps, maintaining a negative pressure state inside the dust collection box. This allows the metal debris generated during drilling to be sucked into the dust collection box through the suction hose, enabling timely cleaning and collection of the metal debris. This prevents debris from scattering on the workbench or in the surrounding environment, keeping the work area clean, reducing the interference of debris on drilling accuracy, improving the processing quality of hardware, preventing debris from splashing and injuring people, effectively ensuring the personal safety of operators, and reducing workplace safety hazards.

[0007] Preferably, the dust collection box is equipped with an arc-shaped filter screen, which is arranged around the exhaust pipe port. When using the device, the arc-shaped filter screen can prevent the exhaust pipe port from becoming blocked, ensuring the smooth progress of subsequent dust collection operations.

[0008] Preferably, the support frame has through slots on both sides, and the vacuum hose passes through the through slots. When using the device, the through slots provide a dedicated passageway for the vacuum hose, preventing the hose from tangling or crossing randomly inside or around the device, making the layout of the entire device more neat and orderly.

[0009] Preferably, a dust collection box has a discharge port on one side, and two limit slide rails are fixed to both sides of the discharge port. The two limit slide rails are fitted with a sealing cover. When using the device, the discharge port can be opened or closed as needed by the cooperation of the limit slide rails and the sealing cover. The discharge port facilitates the removal of collected metal debris.

[0010] Preferably, a second pneumatic cylinder is installed on the top side of the support frame. The working end of the second pneumatic cylinder is equipped with a second pneumatic rod. An electric motor is installed at the bottom end of the second pneumatic rod. The output end of the electric motor is connected to a drill bit. When drilling, the second pneumatic cylinder is activated to move the drill bit down, and at the same time, the electric motor is activated to make the drill bit rotate, thereby completing the drilling operation on the hardware parts.

[0011] Preferably, the base is provided with a placement platform, and the placement platform has a groove. Two movable blocks are slidably assembled in the groove, and clamping plates are fixed to the top of each of the two movable blocks. A bidirectional lead screw is rotatably installed in the groove, and the bidirectional lead screw passes through the movable blocks. A motor is installed on one side wall of the placement platform, and the output end of the motor is connected to one end of the bidirectional lead screw. When clamping and fixing the hardware, the hardware to be processed is placed on the placement platform, the motor is started, and the two movable blocks drive the two clamping plates to move closer to each other until the two clamping plates move to contact the two side walls of the hardware, thereby effectively clamping and fixing the hardware and preventing the hardware from shifting during subsequent drilling.

[0012] Preferably, the placement platform has two limiting grooves, which are located on both sides of the groove. Each limiting groove has two limiting blocks slidably assembled in it, and the top of each limiting block is fixed to the bottom side wall of the clamping plate. When clamping and fixing the hardware, the clamping plate can be limited by the cooperation of the limiting grooves and limiting blocks, so that the clamping plate can move more stably.

[0013] Preferably, a control panel is installed on the side wall of the base, and the control panel is used to control the start and stop of the first pneumatic cylinder, the second pneumatic cylinder, the negative pressure pump, the electric motor and the motor. When using the device, by setting up the control panel, the start and stop control of multiple key components can be integrated together. The operator does not need to operate the switches of each component separately in different locations of the equipment. All related operations can be completed on the control panel, which greatly improves the convenience and efficiency of operation.

[0014] The advantages of this utility model are:

[0015] 1. Before drilling, this utility model first controls the synchronous operation of two first pneumatic cylinders through the control panel. With the cooperation of the limit slide and the slider, the two half-covers are brought closer to each other until the two half-covers are in contact. This can cover the placement platform and the hardware after clamping and fixing, so that the metal debris generated during the drilling process can be completely blocked inside the cover. It can effectively block the metal debris generated during the drilling process, prevent the debris from splashing outside the working area, and facilitate the complete and effective collection of the metal debris later.

[0016] 2. During the drilling process, this utility model controls the synchronous operation of two negative pressure pumps via a control panel, maintaining a negative pressure state inside the dust collection box. This allows metal debris generated during drilling to be sucked into the dust collection box through a suction hose, enabling timely cleaning and collection of metal debris. This prevents debris from scattering on the workbench or in the surrounding environment, keeping the work area clean, reducing interference from debris on drilling accuracy, improving the processing quality of hardware parts, preventing debris from flying and injuring people, effectively protecting the personal safety of operators, and reducing workplace safety hazards.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-5 As shown, a self-cleaning metalworking drilling device includes a base 1, a support frame 2 fixedly connected to the base 1, two limiting grooves 3 on the top side of the base 1, and two sliders slidably mounted in each limiting groove 3. A semi-cover 4 is fitted onto the top of the two sliders at the same end, and a semi-circular hole 7 is provided on each of the two semi-covers 4. First pneumatic cylinders 5 are mounted on the bottom ends of both sides of the support frame 2, and first pneumatic rods 6 are mounted on the actuating ends of the two first pneumatic cylinders 5, with the ends of the first pneumatic rods 6 fixedly connected to the semi-covers. On the body 4, dust collection boxes 8 are installed on both sides of the top of the support frame 2. A suction hose 12 connects the two dust collection boxes 8 to the corresponding half-body 4. A negative pressure pump 9 is installed on each of the two dust collection boxes 8. An air extraction pipe 10 is connected to the input port of the negative pressure pump 9, and an exhaust pipe 11 is connected to the output port of the negative pressure pump 9. During operation, after the hardware is clamped and fixed, before drilling, the control panel 28 controls the synchronous operation of the two first pneumatic cylinders 5. With the cooperation of the limit slide groove 3 and the slider, the two first pneumatic rods 6 drive the two half-body 4. The covers 4 are brought closer together until the two half-covers 4 are in contact. The first pneumatic cylinder 5 stops working, thus covering the placement table 19 and the clamped and fixed hardware. This makes it easy to completely block the metal debris generated during drilling inside the covers. It can effectively block the metal debris generated during drilling and prevent the debris from splashing outside the work area. It is easy to collect the metal debris completely and effectively afterward. During drilling, the control panel 28 controls the synchronous operation of the two negative pressure pumps 9, so that the gas in the dust collection box 8 is extracted by the air extraction pipe 10 and discharged through the exhaust pipe 11. This makes the dust collection box 8 a negative pressure state, so that the metal debris generated during drilling is sucked into the dust collection box 8 through the dust suction hose 12. This allows for timely cleaning and collection of metal debris, preventing debris from scattering on the workbench or in the surrounding environment, keeping the work area clean, reducing the interference of debris on drilling accuracy, improving the processing quality of hardware, preventing debris from splashing and injuring people, effectively protecting the personal safety of operators, and reducing workplace safety hazards.

[0027] An arc-shaped filter screen 13 is installed inside the dust collection box 8, and the arc-shaped filter screen 13 is arranged around the port of the air extraction pipe 10. When the device is in operation, by setting up the arc-shaped filter screen 13, the port of the air extraction pipe 10 can be prevented from being blocked, ensuring the smooth progress of subsequent dust collection operations.

[0028] Both sides of the support frame 2 are provided with through slots 27, and the vacuum hose 12 passes through the through slots 27. When the device is in operation, the through slots 27 provide a dedicated passage path for the vacuum hose 12, preventing the hose from being randomly tangled or crossed inside or around the device, making the layout of the entire device more neat and orderly.

[0029] A dust collection box 8 has a discharge port on one side. Both sides of the discharge port are fixed with limit slide rails 14. The two limit slide rails 14 are fitted with a sealing cover plate 15. When the device is in operation, the discharge port can be opened or closed as needed by the cooperation of the limit slide rails 14 and the sealing cover plate 15. The discharge port facilitates the removal of collected metal scraps.

[0030] Please see Figure 1-2 As shown, a second pneumatic cylinder 16 is installed on the top side of the support frame 2. A second pneumatic rod is fitted to the working end of the second pneumatic cylinder 16. An electric motor 17 is installed at the bottom end of the second pneumatic rod. A drill bit 18 is connected to the output end of the electric motor 17. A control panel 28 is installed on the side wall of the base 1. The control panel 28 is used to control the start and stop of the first pneumatic cylinder 5, the second pneumatic cylinder 16, the negative pressure pump 9, the electric motor 17, and the motor 24. During operation, when drilling a hardware part, the second pneumatic cylinder 16 is started, causing the second pneumatic rod to drive the drill bit 18 to move down. At the same time, the electric motor 17 is started, causing the drill bit 18 to rotate, thereby completing the drilling operation of the hardware part.

[0031] Please see Figure 2 and Figure 5-6 As shown, a placement platform 19 is provided on the base 1. A groove 20 is formed on the placement platform 19, and two movable blocks 22 are slidably mounted within the groove 20. A clamping plate 23 is fixedly connected to the top of each movable block 22. A bidirectional lead screw 21 is rotatably mounted within the groove 20, passing through the movable blocks 22. A motor 24 is mounted on one side wall of the placement platform 19, and the output end of the motor 24 is connected to one end of the bidirectional lead screw 21. Two limiting grooves 25 are formed on the placement platform 19, located on opposite sides of the groove 20. Two limiting blocks 26 are slidably mounted within each limiting groove 25. The top of the limiting block 26 is fixed to the bottom side wall of the clamping plate 23. During operation, before drilling the hardware, it needs to be clamped and fixed. First, the hardware to be processed is placed on the placement table 19. Then, the motor 24 is started, causing the bidirectional lead screw 21 to rotate. With the cooperation of the limiting groove 25 and the limiting block 26, the two movable blocks 22 drive the two clamping plates 23 to move closer to each other until the two clamping plates 23 move to contact the two side walls of the hardware. Then the motor 24 stops working, so that the hardware can be effectively clamped and fixed, avoiding the phenomenon of hardware shifting during subsequent drilling.

[0032] Working Principle: During the drilling process of hardware parts, a large amount of metal debris is generated. Existing drilling equipment for hardware parts processing lacks a self-cleaning mechanism, failing to promptly clean and collect dust and debris. This debris accumulates at the drilling location or on the worktable, interfering with subsequent drilling operations, leading to decreased drilling accuracy, reduced processing quality, and increased risk of metal debris splattering, which can injure the operator's eyes and skin. Therefore, a self-cleaning drilling machine for hardware parts is proposed to address these issues. Hole-making device: Before drilling the hardware, it needs to be clamped and fixed. First, place the hardware to be processed on the placement table 19, then start the motor 24 to make the bidirectional lead screw 21 rotate. With the cooperation of the limit groove 25 and the limit block 26, the two movable blocks 22 drive the two clamping plates 23 to move closer to each other until the two clamping plates 23 move to contact the two side walls of the hardware. Then the motor 24 stops working, so that the hardware can be effectively clamped and fixed, and the hardware can be avoided from shifting during the subsequent drilling process.

[0033] After the hardware is clamped and fixed, before drilling, the control panel 28 controls the synchronous operation of the two first pneumatic cylinders 5. With the cooperation of the limit slide groove 3 and the slider, the two first pneumatic rods 6 drive the two half-covers 4 to move closer to each other until the two half-covers 4 are in contact. The first pneumatic cylinders 5 stop operating, thereby covering the placement table 19 and the clamped hardware. This makes it easier to completely block the metal debris generated during the drilling process inside the cover. It can effectively block the metal debris generated during the drilling process and prevent the debris from splashing outside the working area, making it easier to collect the metal debris completely and effectively in the future.

[0034] After the hardware is clamped and fixed and covered, when drilling the hardware, the second pneumatic cylinder 16 is activated, causing the second pneumatic rod to move the drill bit 18 downward. At the same time, the motor 17 is started, causing the drill bit 18 to rotate, thus completing the drilling operation on the hardware. During the drilling process, the control panel 28 controls the synchronous operation of the two negative pressure pumps 9, so that the gas in the dust collection box 8 is extracted by the air extraction pipe 10 and discharged through the exhaust pipe 11, making the inside of the dust collection box 8 a negative pressure state. This allows the metal debris generated during the drilling process to be sucked into the dust collection box 8 through the dust suction hose 12, thus enabling timely cleaning and collection of metal debris, preventing debris from scattering on the workbench or in the surrounding environment, keeping the work area clean, reducing the interference of debris on drilling accuracy, improving the processing quality of hardware, preventing debris from flying and injuring people, effectively ensuring the personal safety of operators, and reducing workplace safety hazards.
