Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sheet processing, in particular to high-precision sheet multi-hole processing equipment. BACKGROUND

[0002] At present, the application range of metal ultra-thin sheet parts is very wide, and the dimensional accuracy and geometric accuracy often have a great influence on the performance of the parts. When drilling the sheet, the sheet is easy to be plastically deformed due to the small thickness and poor rigidity in the drilling process. The residual stress in the material will be redistributed in the processing process, resulting in aggravated deformation. In addition, during drilling, the drill bit will adhere to the waste, affecting the subsequent processing accuracy and the service life of the drill bit. The waste generated during drilling is also easy to fly around, causing environmental pollution and difficult to clean. Therefore, it is necessary to design high-precision sheet multi-hole processing equipment to improve the above problems. SUMMARY

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] 1. This invention uses a telescopic cylinder to drive the support seat upward, so that the top surface of the support seat contacts the bottom surface of the thin plate to be processed. When the drilling tool contacts the thin plate for processing, the support seat can provide rigid support for the drilling part of the thin plate, thereby reducing the deformation of the drilling part of the thin plate and improving the processing quality of the thin plate. The mounting seat and the mounting plate are connected by the first fixed rod, the second fixed rod and the guide slide rod, so that when the position of the mounting seat is adjusted in the X-axis, Y-axis and Z-axis directions, the mounting plate moves synchronously with the mounting seat, thereby ensuring that the position of the moving protective cylinder and the support seat always corresponds vertically, and the adjustment is quick, flexible and convenient.

[0025] 2. This invention, through its protective mechanism, allows the movable protective cylinder to initially contact the thin plate during drilling. As the mounting base continues to descend, the movable protective cylinder moves upward relative to the fixed protective cylinder, protecting the drilling tool and preventing debris from splashing during drilling. Furthermore, as the mounting base moves downward, the movable protective cylinder moves upward, causing the positioning rod to move upward synchronously. The positioning rod, connected to the first annular air bladder via a connecting plate, causes the first annular air bladder to expand, allowing gas to enter and be stored within it through the first air inlet pipe. When the mounting base moves upward to its reset position, the movable protective cylinder is pushed downward by the elastic element. At this time, the positioning rod moves downward synchronously with the movable protective cylinder, causing the first annular air bladder to contract. The gas stored within the first annular air bladder is then transported from the first air supply pipe into the air blowing pipe, and finally blown onto the drilling tool through the air blowing nozzle. This effectively removes debris adhering to the drilling tool, ensuring processing quality and extending the tool's service life.

[0026] 3. In this invention, during drilling, the debris falls into the clearance hole, then into the inclined chip removal hole, and finally is discharged from the downward-facing chip outlet of the chip removal pipe into the waste chip collection box for centralized collection. This avoids the problem of waste chips splashing randomly and causing environmental pollution around the processing equipment. When the telescopic cylinder drives the support seat to move upward to support the thin plate, the support seat drives the second annular air bladder to extend. At this time, gas enters the second annular air bladder from the second air inlet pipe and is stored there. When the drilling operation is completed, the telescopic cylinder drives the support seat to move downward, and the support seat drives the second annular air bladder to contract. The gas stored in the second annular air bladder is transported into the blowing hole through the second air supply pipe. The inclined blowing hole can blow gas into the clearance hole to push the waste chips in the clearance hole, chip removal hole and chip removal pipe, preventing the waste chips from accumulating and causing blockage.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0051] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example: Figures 1 to 10 As shown, embodiments of the present invention provide a high-precision thin plate multi-hole processing equipment, including a machine tool 1, a thin plate fixing mechanism 2, a mounting base 6, a drilling mechanism 7, a displacement module, a protective mechanism 8, a bottom bearing mechanism 9, and a linkage rod 10.

[0053] In this embodiment, as Figure 2 and Figure 3As shown, the thin plate retaining mechanism 2 is installed on the top of the machine tool 1 and is used to clamp and position the thin plate. The thin plate retaining mechanism 2 includes a first X-axis slide rail 209 fixedly connected to the front and rear ends of the top of the machine tool 1. Two support plates 201 are slidably connected between the two first X-axis slide rails. A first Y-axis slide rail 202 is fixedly connected to the top of each support plate 201. Two positioning baffles 203 are slidably connected to each first Y-axis slide rail 202. The top view of the positioning baffle 203 is an L-shaped structure design. A connecting telescopic rod 208 is fixedly connected between two adjacent positioning baffles 203 along the X-axis direction. A first bidirectional lead screw 205 is installed on the top of one of the support plates 201 through a bearing seat. Two positioning baffles 203 are located at the first bidirectional lead screw 205. A first threaded sleeve 204, threadedly connected to the first bidirectional lead screw 205, is fixedly connected to the bottom of the baffle 203. Two first threaded sleeves 204 are threadedly connected to the two sides of the first bidirectional lead screw 205 with opposite rotation directions. A first guide rod 207 is fixedly connected to the top of another support plate 201. Two positioning baffles 203 located at the first guide rod 207 are fixedly connected to the bottom of two positioning baffles 203, with first guide sleeves 206 slidably connected to the first guide rod 207. A second bidirectional lead screw 211 is mounted on the front end of the machine tool 1 via a bearing seat. A second threaded sleeve 210, threadedly connected to the second bidirectional lead screw 211, is fixedly connected to the bottom of the front end of the support plate 201. Two second threaded sleeves 210 are threadedly connected to the two sides of the second bidirectional lead screw 211 with opposite rotation directions. A second guide rod 213 is fixedly connected to the bottom rear end of the support plate 201. A second guide sleeve 212, which is slidably connected to the second guide rod 213, is fixedly connected to the bottom rear end of the support plate 201. A rotating handwheel is fixedly connected to one end of the first bidirectional lead screw 205 and the second bidirectional lead screw 211. When clamping the positioning plate, rotating the first bidirectional lead screw 205 drives the two first threaded sleeves 204 to move closer or further away from each other synchronously, thereby adjusting the distance between the two positioning baffles 203 connected to the first threaded sleeves 204 in the Y-axis direction. The other two positioning baffles 203 move synchronously under the connection of the telescopic rod 208. The positioning baffles 203 slide on the first guide rod 207 through the first guide sleeve 206, improving the stability of the position adjustment. The second bidirectional lead screw 211 drives the two second threaded sleeves 210 to move closer or further apart synchronously, thereby adjusting the distance between the two support plates 201 in the X-axis direction. This, in turn, adjusts the distance between the positioning baffles 203 in the X-axis direction, allowing the positions of the four positioning baffles 203 to be adjusted to fit the size specifications of the thin plate and clamp and position it. In this embodiment, each positioning baffle 203 may also be equipped with a pneumatic gripper assembly for clamping and positioning a portion of the thin plate placed on the positioning baffle 203, thereby improving the positioning and fixing effect of the thin plate. The thin plate fixing mechanism 2 in this embodiment is one implementation method for clamping and positioning the thin plate. Any existing structure that can achieve clamping and positioning of the thin plate can be replaced and used as needed.

[0054] In this embodiment, as Figure 5 and Figure 6 As shown, the drilling mechanism 7 is mounted on the mounting base 6. The drilling mechanism 7 includes a drive motor 701 fixedly mounted on the top of the mounting base 6. The output end of the drive motor 701 passes through the mounting base 6 and is fixedly connected to a tool holder 702. A drilling tool 703 is detachably mounted on the bottom of the tool holder 702. The drive motor 701 drives the tool holder 702 to rotate the drilling tool 703, thereby realizing the drilling of the thin plate.

[0055] In this embodiment, as Figure 4 As shown, the displacement module is used to adjust the positions of the mounting base 6 and the drilling mechanism 7 in the X, Y, and Z axes. The displacement module includes a Y-axis traveling mechanism 3, an X-axis traveling mechanism 4, and a Z-axis traveling mechanism 5. The mounting base 6 is fixedly connected to the slide of the Z-axis traveling mechanism 5. The Z-axis traveling mechanism 5 drives the mounting base 6 and the drilling mechanism 7 to move along the Z-axis. The Z-axis traveling mechanism 5 is fixedly connected to the slide of the X-axis traveling mechanism 4. The X-axis traveling mechanism 4 drives the Z-axis traveling mechanism 5 to move along the X-axis. The Y-axis traveling mechanism 3 is fixedly connected to the machine tool 1. The X-axis traveling mechanism 4 is fixedly connected to the slide of the Y-axis traveling mechanism 3. The X-axis traveling mechanism 3 is used to drive the X-axis traveling mechanism 4 to move along the Y-axis direction. The spatial position of the drilling mechanism 7 in the X, Y, and Z-axis directions is adjusted by the Y-axis traveling mechanism 3, X-axis traveling mechanism 4, and Z-axis traveling mechanism 5, so that multi-hole drilling can be performed at multiple positions on the thin plate. It should be understood that the Y-axis traveling mechanism 3, X-axis traveling mechanism 4, and Z-axis traveling mechanism 5 can be set as a combination of servo motor and ball screw, or linear motor. In addition, the Y-axis traveling mechanism 3, X-axis traveling mechanism 4, and Z-axis traveling mechanism 5 can be used with a PLC controller to achieve automatic control of the stroke through preset parameters.

[0056] In this embodiment, as Figure 5 and Figure 6As shown, the protective mechanism 8 is mounted on the mounting base 6. The protective mechanism 8 includes a telescopic protective assembly disposed on the outside of the drilling tool 703. The telescopic protective assembly includes a fixed protective cylinder 801 fixedly connected to the bottom of the mounting base 6. The fixed protective cylinder 801 is sleeved on the outside of the tool holder 702 and the drilling tool 703. The outer side of the fixed protective cylinder 801 is axially slidably connected to the movable protective cylinder 802. A fixed ring plate 8021 is fixedly connected to the outer side of the top of the movable protective cylinder 802. Multiple positioning rods 803 are fixedly connected at equal intervals along the circumferential direction on the top of the fixed ring plate 8021. A through hole is opened on the mounting base 6 corresponding to the positioning rod 803. The top of the positioning rod 803 slides through the through hole. The mounting base 6 is located between the fixed ring plate 8021 and the positioning rod 803. An elastic element 804 is fitted on the outer side, preferably a helical spring. The first cleaning component is used to blow gas to the drilling tool 703 to clean up the debris. When the elastic element 804 is not under force, the moving protective cylinder 802 is pushed by the thrust of the elastic element 804, so that the bottom of the moving protective cylinder 802 is placed below the drilling tool 703, which can completely cover the drilling tool 703. When drilling thin plates, the Z-axis traveling mechanism 5 drives the mounting base 6 and the drilling mechanism 7 to descend. The moving protective cylinder 802 first contacts the thin plate. As the mounting base 6 continues to descend, the moving protective cylinder 802 moves upward relative to the fixed protective cylinder 801, which can protect the drilling tool 703 during drilling operations and prevent debris from splashing during drilling operations.

[0057] In this embodiment, as Figure 5 and Figure 6As shown, the protective mechanism 8 also includes a first cleaning component, which includes a first annular air bladder 805 fixedly connected to the top of the mounting base 6. The first annular air bladder 805 is sleeved on the outside of the drive motor 701. A connecting plate 806 is fixedly connected between the top end of the positioning rod 803 and the top end of the first annular air bladder 805. A first air inlet pipe 807 is fixedly connected to the outside of the first annular air bladder 805. A first one-way valve is provided on the first air inlet pipe 807. The gas flow direction of the first one-way valve is such that the air inlet of the first air inlet pipe 807 faces the first annular air bladder 805. A filter cover is installed at the air inlet of component 7. The first cleaning component also includes an air blowing pipe 809 fixedly connected to the inside of the movable protective cylinder 802 near the bottom. The air blowing pipe 809 has a ring structure design, and multiple air blowing nozzles 810 are fixedly connected to the air blowing pipe 809. The air blowing direction of the air blowing nozzles 810 is towards the drilling tool 703. The air blowing pipe 809 is connected to the first annular air bladder 805 through a first air supply pipe 808. A second one-way valve is installed on the first air supply pipe 808. The gas flow direction of the second one-way valve is from the first annular air bladder 805 towards the air blowing pipe 809. During drilling operations, when the installation... When the mounting base 6 moves downward, the movable protective cylinder 802 moves upward, causing the positioning rod 803 to move upward simultaneously. The positioning rod 803 is connected to the first annular air bladder 805 via the connecting plate 806, causing the first annular air bladder 805 to extend, allowing gas to enter and be stored in the first annular air bladder 805 through the first air inlet pipe 807. The filter cover installed at the air inlet of the first air inlet pipe 807 can filter the gas entering the first annular air bladder 805, preventing contamination inside the first annular air bladder 805. When the mounting base 6 moves upward, the movable protective cylinder 802 is pushed downward by the elastic element 804. Upon resetting, the positioning rod 803 moves downward synchronously with the moving protective cylinder 802. The positioning rod 803 causes the first annular air bladder 805 to contract, and the gas stored in the first annular air bladder 805 is transported from the first air supply pipe 808 into the air blowing pipe 809. Then, the gas is blown onto the drilling tool 703 through the air blowing nozzle 810, which can remove the waste chips adhering to the drilling tool 703. Furthermore, the air blowing pipe 809 and the air blowing nozzle 810 move together with the reset moving protective cylinder 802, which can blow and clean the entire processing part of the drilling tool 703, ensuring processing quality and improving the service life of the drilling tool 703.

[0058] As a preferred embodiment of this example, a debris suction and cleaning device may be provided on the protective mechanism 8 to remove debris from the fixed protective cylinder 801 and the movable protective cylinder 802.

[0059] In this embodiment, as Figure 5 and Figure 6As shown, the bottom support mechanism 9 is located inside the machine tool 1. The bottom support mechanism 9 includes a mounting plate 904, on which a telescopic cylinder 907 is fixedly mounted. The output end of the telescopic cylinder 907 passes through the mounting plate 904 and is fixedly connected to a support seat 905. The support seat 905 corresponds vertically to the position of the movable protective cylinder 802. A clearance hole 9051 corresponding to the position of the drilling tool 703 is opened at the center of the support seat 905. A second cleaning component is provided between the support seat 905 and the mounting plate 904. The bottom support mechanism 9 also includes a position adjustment component. Before drilling operations, the telescopic cylinder 907... In the retracted state (07), a certain distance is left between the support seat 905 and the sheet metal to be processed. The position adjustment component moves the support seat 905 to a position corresponding to the vertical position of the moving protective cylinder 802, preventing the support seat 905 from scratching the bottom surface of the sheet metal to be processed. Then, the telescopic cylinder 907 drives the support seat 905 to move upward, so that the top surface of the support seat 905 contacts the bottom surface of the sheet metal to be processed. When the drilling tool 703 contacts the sheet metal for processing, the support seat 905 can provide rigid support for the drilling part of the sheet metal, thereby reducing the degree of deformation of the drilling part of the sheet metal and improving the processing quality of the sheet metal.

[0060] In this embodiment, as Figure 5 and Figure 7 As shown, a first outer edge support ring plate 8022 is provided on the bottom outer side of the movable protective cylinder 802. The first outer edge support ring plate 8022 is integrally formed with the movable protective cylinder 802. A second outer edge support ring plate 9054 is provided on the top outer side of the bearing seat 905. The second outer edge support ring plate 9054 is integrally formed with the bearing seat 905. The first outer edge support ring plate 8022 can increase the contact area between the movable protective cylinder 802 and the thin plate, and the second outer edge support ring plate 9054 can increase the contact area between the bearing seat 905 and the thin plate, thereby optimizing the stress distribution at the drilling part of the thin plate, dispersing local stress, and improving the support effect.

[0061] In this embodiment, as Figure 7 , Figure 8 and Figure 9As shown, the diameter of the clearance hole 9051 of the bearing seat 905 is larger than the diameter of the drilling tool 703. When the drilling tool 703 passes through the thin plate, it is placed inside the clearance hole 9051. The clearance hole 9051 is used to avoid the position of the drilling tool 703 and prevent the drilling tool 703 from contacting the bearing seat 905. Chip removal holes 9052 communicating with the clearance hole 9051 are opened on both sides of the outer wall of the bearing seat 905. The chip removal holes 9052 are along the clearance hole 9051 toward the bearing seat 905. The outer wall of the bearing seat 905 is inclined downward. A chip removal pipe 906 is fixedly connected to the chip removal hole 9052 on the outer wall of the bearing seat 905. The chip outlet of the chip removal pipe 906 is set downward. The chips during drilling fall into the clearance hole 9051, then into the inclined chip removal hole 9052, and then are discharged from the downward-facing chip outlet of the chip removal pipe 906. This allows the waste chips to fall into the bottom of the machine tool 1, avoiding the problem of waste chips splashing randomly and causing environmental pollution around the processing equipment.

[0062] In this embodiment, as Figure 7 and Figure 9 As shown, the second cleaning component includes a second annular air bladder 908 fixedly connected between the bottom of the support 905 and the mounting plate 904. A second air inlet pipe 909 is fixedly connected to the outside of the second annular air bladder 908. A third one-way valve is provided on the second air inlet pipe 909, with the gas flow direction of the third one-way valve being from the air inlet of the second air inlet pipe 909 towards the second annular air bladder 908. A filter cover is provided at the air inlet of the second air inlet pipe 909. An air blowing hole 9053 is provided between the outer wall of the support 905 and the clearance hole 9051. The clearance hole 9051 is inclined downward along the outer wall of the support 905 towards the clearance hole 9051. The second annular air bladder 908 and the clearance hole 9051 are connected by a second air supply pipe 910. A fourth one-way valve is provided on the second air supply pipe 910, with the gas flow direction of the fourth one-way valve being from the second annular air bladder 908 towards the air blowing hole 9053. When the telescopic cylinder 907 drives the support seat 905 to move upward to support the thin plate, the support seat 905 drives the second annular air bladder 908 to extend. At this time, gas enters the second annular air bladder 908 from the second air inlet pipe 909 and is stored there. The filter cover set at the air inlet of the second air inlet pipe 909 can filter the gas entering the second annular air bladder 908 and avoid contamination inside the second annular air bladder 908. After the drilling operation is completed, the telescopic cylinder 907 drives the support seat 905 to move downward. The support seat 905 drives the second annular air bladder 908 to contract and transport the gas stored in the second annular air bladder 908 into the blowing hole 9053 through the second air supply pipe 910. The inclined blowing hole 9053 can blow gas into the clearance hole 9051 to push the waste chips in the clearance hole 9051, the chip discharge hole 9052 and the chip discharge pipe 906 to prevent the waste chips from accumulating and causing blockage.

[0063] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the linkage 10 connects the mounting base 6 and the mounting plate 904. The linkage 10 includes a first fixed rod 1001 and a second fixed rod 1003. One end of the first fixed rod 1001 is fixedly connected to the mounting base 6, and one end of the second fixed rod 1003 is fixedly connected to the mounting plate 904. A vertically arranged guide slide rod 1002 is fixedly connected to the bottom of the first fixed rod 1001 at the end away from the mounting base 6. A long through groove 101 is opened on the back of the machine tool 1 along the X-axis direction. The end of the second fixed rod 1003 away from the mounting plate 904 passes through the long through groove 101 and is fixedly connected to a sliding sleeve. The guide slide rod 1002 slides. The mounting base 6 and the mounting plate 904 are connected by a first fixed rod 1001, a second fixed rod 1003, and a guide slide rod 1002, which are inserted into the sliding sleeve. When the mounting base 6 is adjusted in the X-axis and Y-axis directions, the mounting plate 904 moves synchronously with the mounting base 6. When the mounting base 6 is adjusted in the Z-axis direction, the guide slide rod 1002 slides in the sliding sleeve of the second fixed rod 1003. This ensures that the position of the mounting plate 904 along the Z-axis does not change when the mounting base 6 moves along the Z-axis, thereby ensuring that the position of the movable protective cylinder 802 and the bearing seat 905 always corresponds vertically, and the adjustment is quick, flexible and convenient.

[0064] In this embodiment, as Figure 3 As shown, the position adjustment assembly includes a second X-axis slide rail 901 fixedly connected to the front and rear ends of the machine tool 1 along the X-axis direction. A movable plate 902 is slidably connected between the two second X-axis slide rails 901. A second Y-axis slide rail 903 is fixedly connected to the top of the movable plate 902 along the Y-axis direction. A mounting plate 904 is slidably connected to the second Y-axis slide rail 903. The mounting plate 904 slides on the second Y-axis slide rail 903 to adjust the position of the mounting plate 904 in the Y-axis direction. The movable plate 902 slides on the second X-axis slide rail 901 to adjust the position of the mounting plate 904 in the X-axis direction. This assembly provides stable support for the mounting plate 904 and improves the smoothness of the position adjustment of the mounting plate 904.

[0065] In this embodiment, as Figure 10As shown, the front end of the machine tool 1 has an installation port 102, and a waste chip collection box 11 is detachably installed in the installation port 102. The bottom of the machine tool 1 is inclined downward along the installation port 102 towards its interior. The shape of the waste chip collection box 11 is adapted to the shape of the bottom of the machine tool 1. Several rollers are rotatably connected to the bottom of the machine tool 1. The rollers reduce the friction between the waste chip collection box 11 and the machine tool 1, making it easy to install the waste chip collection box 11 from the installation port 102 into the bottom of the machine tool 1. The inclined installation position at the bottom of the machine tool 1 effectively prevents the waste chip collection box 11 from falling out of the machine tool 1. The waste chip collection box 11 can collect the waste chips discharged from the chip discharge pipe 906 of the bottom support mechanism 9, which is convenient for the collection and cleaning of waste chips.

[0066] Working principle: During processing, the thin plate to be processed is clamped and positioned by the thin plate fixing mechanism 2. Then, the drilling mechanism 7 is adjusted in the X and Y axes by the Y-axis traveling mechanism 3 and the X-axis traveling mechanism 4, so that the mounting base 6 and the drilling mechanism 7 move to the drilling position of the thin plate. The mounting base 6 and the mounting plate 904 are connected by the first fixing rod 1001, the second fixing rod 1003 and the guide slide rod 1002, so that when the mounting base 6 is adjusted in the X and Y axes, the mounting plate 904 moves synchronously with the mounting base 6, ensuring that the moving protective cylinder 802 and the bearing seat 905 are vertically aligned. The telescopic cylinder 907 drives the bearing seat 905 to move upward, so that the bearing seat 905... The top surface of the 05 contactes the bottom surface of the sheet metal to be processed, providing rigid support for the drilling area. Simultaneously, the support seat 905 extends the second annular air bladder 908, allowing gas to enter and be stored within it via the second air inlet pipe 909. The gas is then driven by the drive motor 701, which in turn drives the tool holder 702 to rotate the drilling tool 703. Under the action of the Z-axis travel mechanism 5, the mounting seat 6 and drilling mechanism 7 move downwards along the Z-axis. The moving protective cylinder 802 first contacts the sheet metal. As the mounting seat 6 continues to descend, the moving protective cylinder 802 moves upwards relative to the fixed protective cylinder 801, protecting the drilling tool 703 during drilling operations and preventing debris from splashing. The drilling tool 703 then contacts the sheet metal... During drilling, when the drilling tool 703 contacts the thin plate, the support seat 905 provides rigid support for the drilling part of the thin plate, thereby reducing the deformation of the drilling part and improving the processing quality of the thin plate. When the movable protective cylinder 802 moves, it drives the positioning rod 803 to move upward synchronously. The positioning rod 803 is connected to the first annular air bladder 805 through the connecting plate 806, which causes the first annular air bladder 805 to extend, allowing gas to enter and be stored in the first annular air bladder 805 from the first air inlet pipe 807. The drilling chips fall into the clearance hole 9051 of the support seat 905, then into the inclined chip discharge hole 9052, and finally out through the downward-facing chip outlet of the chip discharge pipe 906 into the chip collection. The gas is collected in box 11. After drilling is completed, the mounting base 6 and drilling mechanism 7 are moved upward and reset again by the Z-axis traveling mechanism 5. The positioning rod 803 moves downward synchronously with the moving protective cylinder 802. The positioning rod 803 causes the first annular air bladder 805 to contract, and the gas stored in the first annular air bladder 805 is transported from the first air supply pipe 808 into the air blowing pipe 809. Then, the gas is blown onto the drilling tool 703 through the air blowing nozzle 810, which can remove the waste adhering to the drilling tool 703. The air blowing pipe 809 and the air blowing nozzle 810 move together with the reset moving protective cylinder 802, which can blow air to clean the entire machined part of the drilling tool 703. Then, the telescopic cylinder 907 drives the carrier 905 to move downward.The support seat 905 causes the second annular air bladder 908 to contract, delivering the gas stored in the second annular air bladder 908 into the air blowing hole 9053 through the second air supply pipe 910. The inclined air blowing hole 9053 blows gas into the clearance hole 9051, pushing waste chips within the clearance hole 9051, chip removal hole 9052, and chip removal pipe 906, preventing chip accumulation and blockage. This completes the drilling of one hole in the thin plate. Then, the Y-axis travel mechanism 3 and X-axis travel mechanism 4 readjust the spatial position of the drilling mechanism 7 in the X and Y axes. Following the above steps, multi-hole drilling on the thin plate is achieved.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
