Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a hydraulic tapping process and apparatus for pressurized pipelines. Background Technology

[0002] Early pipe drilling devices consisted of only a drill bit and a manual clamping component. These tools were simple in structure, low in cost, and highly portable, but they had significant drawbacks: no protection or chip removal function; the drill bit was exposed throughout the process, posing a risk of accidental injury; cutting chips were scattered everywhere, easily contaminating the working environment, and the chips could easily enter the drill bit clamping gap, affecting subsequent use.

[0003] Patent publication number CN219561474U includes a fixed plate, a clamping and positioning mechanism, and a movable drilling mechanism, both of which are mounted on the fixed plate. By using guide rods, fixing blocks, and springs, along with a screw, the height of the movable plate can be adjusted. By using a bidirectional lead screw, the distance between the limiting rods can be adjusted. Combined with the limiting block and the positioning block mounted on the movable plate, this device can accommodate pipe openings of different diameters.

[0004] The aforementioned patent has obvious limitations in practice: with the drill bit exposed, operators are very likely to accidentally touch the sharp drill bit edge when adjusting, cleaning, replacing pipes, or organizing tools, causing scratches and cuts; when drilling, the drill bit rotates at high speed, and without the protective barrier formed by the protective sleeve, the operator's hands or clothing may be accidentally caught in the cutting area, causing serious entanglement accidents. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a combined processing technology and apparatus for hydraulic tapping of pressurized pipelines, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a hydraulic drilling combined processing device for pressurized pipes, comprising a base and a track rod installed on the base, a slide block installed on the track rod, a drill bit installed on the slide block, and the combined processing device further comprising a moving mechanism and a protective mechanism installed on the moving mechanism; The moving mechanism includes a guide rail frame mounted on the slide block and a slide mounted on the drill bit, for driving the drill bit to move during operation; The protective mechanism includes a left protective mechanism and at least one right protective mechanism that is spaced apart from the left protective mechanism, for protecting the drill bit in a non-operating state; The left and right protective mechanisms each include a connecting rod, a baffle mounted on the connecting rod, a connecting frame mounted on the baffle, and a protective sleeve connected to the connecting frame. A connecting rod for driving the baffle to rotate is mounted on the baffle. The fixed end of the connecting rod is mounted on the slide. The movement of the drill bit drives the slide to move, causing the slide to move along the inner wall of the guide rail. The movement of the slide will drive the connecting rod to move. The force on the connecting rod will also generate a force at its connection with the baffle, causing the baffle to gradually rotate outward along the connecting rod. The rotation of the baffle will also drive the connecting frame to move. The movement of the connecting frame will drive the protective sleeve to move, so that the protective sleeve will unfold synchronously during drilling, forming a protective barrier around the drill bit.

[0007] According to the above technical solution, the protective mechanism further includes a rack rod installed on the slide and a gear installed on the guide rail frame, wherein the rack rod meshes with the gear.

[0008] According to the above technical solution, the combined processing device further includes a clamping device installed on the base, a left fixing mechanism installed on the sliding seat, and at least one right fixing mechanism arranged at a distance from the left fixing mechanism, for clamping and fixing the pipe. The clamping device includes a mounting block installed on the base and a servo motor installed on the mounting block. A reciprocating screw and a sliding seat installed on the reciprocating screw are mounted on the extension end of the servo motor, for realizing the step-by-step supply of the pipe. The reciprocating screw is driven to rotate by the rotation of the extension end of the servo motor. The rotation of the reciprocating screw enables the sliding seat to move back and forth through its own characteristics. The movement of the sliding seat will drive the clamping pads on both sides to move, that is, drive the pipe to move. The left and right fixing mechanisms each include a sliding rod mounted on the sliding seat, a clamping pad mounted on the sliding rod for fixing the pipe, and a first spring disposed between the clamping pad and the sliding seat. The front side of the clamping pad is set as an inclined surface, so that the outer wall of the pipe first contacts the inclined surface of the clamping pad, causing the clamping pads on both sides to be forced to move the sliding rod in opposite directions, and simultaneously compressing the first spring at their respective positions. Finally, after the pipe is fully inserted, the first spring resets and causes the clamping pads on both sides to clamp the outer wall of the pipe.

[0009] According to the above technical solution, the clamping device further includes a limiting mechanism installed on the mounting block. The limiting mechanism includes a hollow block installed on the sliding rod for automatically releasing the clamped state of the pipe, and a limiting plate installed on the mounting block for limiting the maximum moving distance and maximum thickness of the pipe. The inner wall of the hollow block is provided with an inclined groove.

[0010] According to the above technical solution, the clamping device further includes a drive mechanism and a cleaning mechanism installed on the base. The drive mechanism includes a second servo motor and a cylinder installed on the extension end of the second servo motor. The extension end of the cylinder has a groove. The cleaning mechanism includes a prism plate installed on the extended end of the cylinder. The prism plate is provided with a brush for contacting the inner wall of the pipe to clean impurities. The extension end of the servo motor rotates to drive the fixed end of the cylinder to rotate, so that the extension action can drive the brush on the surface of the prism plate to penetrate into the inner wall of the pipe.

[0011] According to the above technical solution, the clamping device further includes a limiting mechanism installed on the cleaning mechanism to restrict the extension and retraction of the cylinder, including a hollow rod installed on the limiting plate and a limiting rod installed inside the hollow rod. A second spring is provided between the hollow rods to drive the limiting rod to reset. A rack is provided on the hollow rod to mesh with the gear. The bottom of the limiting rod is set as an inclined surface. When the cylinder is idle, the non-inclined surface of the hollow rod is inserted into the groove at the extension end of the cylinder to restrict it, so that the cylinder cannot extend. When the drill bit is working, that is, when the rack moves downward, the rotation of the gear meshes with the rack on the hollow rod, causing the hollow rod to move upward. The movement of the hollow rod will drive the limiting rod to move, so that the limiting rod disengages from the groove. At this time, the extension end of the cylinder can extend normally.

[0012] According to the above technical solution, the combined processing device further includes a post-processing device installed on the base, used to collect the output and residue of the pipe after drilling. The post-processing device includes a chute opened on the base and a sliding plate matching the chute. A fence frame is installed on the chute, and a pull rod for driving the sliding plate to move is installed on the sliding plate. A pressure plate for compressing debris is slidably installed on the fence frame. A rubber rod that can be bent by thrust is provided on the top of the pressure plate, so that the movement of the rubber rod drives the pressure plate to move. The movement of the pressure plate will compact the loose debris into blocks, thereby compressing the volume of the debris and greatly increasing the single-time capacity of the fence frame.

[0013] According to the above technical solution, the post-processing device further includes a mounting pad installed on the sliding seat, a guide rod installed on the mounting block, and a guide plate installed on the mounting pad to prevent debris from contacting the reciprocating lead screw. The guide plate is pulled by the guide rod.

[0014] According to the above technical solution, the post-processing device further includes a touch rod installed on the guide plate and a release rod installed on the base for releasing the pipe from the clamped state. When the sliding seat is reset, the hollow block moves and eventually the inclined groove opened on the inner wall is released from the release rod, so that the hollow block is forced to move outward and the clamped state is released at the same time.

[0015] Furthermore, the present invention also provides a process for a hydraulic tapping assembly for pressurized pipes, which uses the aforementioned hydraulic tapping assembly for pressurized pipes and includes the following steps: Step 1: After the workers have secured the pipe, the slide block is moved downwards along the track rod using hydraulic pressure. The movement of the slide block drives the drill bit to move. The drill bit converts the rotational power into cutting force through electric power to complete the pipe drilling. Step 2: When the drill bit is not in operation, close the protective sleeves on both sides to form a closed cover, completely covering the high-speed rotating parts and preventing operators from accidentally touching, cleaning or adjusting the cutting edge of the drill bit. Step 3: Preventing proximity and isolation while the drill bit is in operation: The movement of the drill bit drives the slide to move, causing the slide to move along the inner wall of the guide rail. The movement of the slide will drive the connecting rod to move, and the force on the connecting rod will also generate force at the connection point with the baffle, causing the baffle to gradually rotate outward along the connecting rod. At the same time as the baffle rotates, it will also drive the connecting frame to move, and the movement of the connecting frame will drive the protective sleeve to move, so that the protective sleeve will unfold synchronously during drilling, forming a protective barrier around the drill bit.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, through the installation of a protective device, after the worker has fixed the pipe, the drill bit is moved hydraulically and electrically to convert the rotational power into cutting force to complete the drilling of the pipe. When the drill bit is not in operation, the protective sleeves on both sides close to form a closed cover, completely covering the high-speed rotating parts, preventing operators from accidentally touching, cleaning, or adjusting the cutting edge of the drill bit, thus preventing safety accidents such as scratches and cuts. At the same time, it can prevent tools, parts, and other foreign objects from falling into the clamping part of the drill bit, avoiding jamming when starting it again. When the drill bit is in operation, it prevents people from getting close to it, physically restricting personnel's hands and clothing from getting close to the cutting area, eliminating the risk of being entangled due to the high-speed rotation of the drill bit and the shaking of the workpiece during processing.

[0017] 2. In this invention, by setting up a clamping device, the wedge-shaped force amplification and displacement compensation characteristics of the inclined plane are utilized, so that there is no need to change special clamps for different pipe diameters, which greatly reduces the tooling switching cost. After drilling, the loose debris attached to the pipe wall surface is removed to avoid subsequent process failures caused by debris residue. When the cylinder is idle, it is restricted by inserting the non-inclined surface of the hollow rod into the groove at the cylinder extension end, so that the limit of the cylinder extension end will be released synchronously only after the drill bit starts cutting and enters the working stroke. When the drill bit is not working, the cylinder extension end is forcibly locked in the retracted position, which can avoid cylinder malfunction, such as the cylinder extending prematurely before the drill bit contacts the pipe, causing the brush to collide with the drill bit and the pipe end face, or the mechanism jamming caused by the overlap of the cleaning process and the drilling process.

[0018] 3. In this invention, the post-processing device fully covers the reciprocating lead screw, guiding the cutting debris to fall to both sides of the lead screw. This limits the debris's fall path, allowing for directional collection and preventing debris from splashing onto the ground or around the equipment. It also completely prevents debris from falling into the lead screw thread gap, preventing debris from mixing with lubricating grease to form sludge, reducing friction and wear on the lead screw, and extending the lead screw's feed accuracy and service life. The pressure plate compacts the loose debris into blocks, compressing the debris volume and significantly increasing the single-time capacity of the fence frame. This prevents debris from scattering and becoming difficult to clean. By manually pulling the lever, the slide plate moves along the chute, causing the debris base to fall out. When the sliding seat resets, the clamping state is released, and the pipe falls onto the mounting pad, allowing the operator to remove the pipe normally. This eliminates the need for manual force, significantly reducing the operational burden, and is especially suitable for high-frequency, long-term continuous operation scenarios.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described 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. Example 1

[0022] Please see Figures 1-10 One embodiment of the present invention is: a hydraulic tapping combined processing device for pressurized pipes, including a base 1 and a track rod 2 installed on the base 1, a slide block 3 installed on the track rod 2, a drill bit 4 installed on the slide block 3, and the combined processing device also includes a moving mechanism and a protective mechanism installed on the moving mechanism. The moving mechanism includes a guide rail frame 10 mounted on the slide block 3 and a slide 11 mounted on the drill bit 4, for driving the drill bit 4 to move during operation; The protective mechanism includes a left protective mechanism and at least one right protective mechanism that is spaced apart from the left protective mechanism, for protecting the drill bit 4 when it is not in operation; The left and right protective mechanisms each include a connecting rod 12, a baffle 13 mounted on the connecting rod 12, a connecting frame 14 mounted on the baffle 13, and a protective sleeve 15 connected to the connecting frame 14. A connecting rod 16 for driving the baffle 13 to rotate is mounted on the baffle 13. The fixed end of the connecting rod 16 is mounted on the slide 11 to prevent operators from accidentally touching, cleaning, or adjusting the cutting edge of the drill bit 4, thus preventing scratches, cuts, and other safety accidents. At the same time, it can prevent tools, parts, and other foreign objects from falling into the clamping part of the drill bit 4, thus preventing jamming during the next start-up.

[0023] The protective mechanism also includes a rack 17 mounted on the slide 11 and a gear 18 mounted on the guide rail 10, with the rack 17 meshing with the gear 18.

[0024] In this embodiment, during operation: after the worker has secured the pipe, the slide block 3 moves downwards along the track rod 2 via hydraulic pressure. The movement of the slide block 3 drives the drill bit 4 to move. Electric power converts the rotational power of the drill bit 4 into cutting force, completing the pipe drilling. When the drill bit 4 is not in operation, the protective sleeves 15 on both sides close to form a sealed cover, completely concealing the high-speed rotating components. This prevents operators from accidentally touching, cleaning, or adjusting the cutting edge of the drill bit 4, thus preventing scratches, cuts, and other safety accidents. It also prevents tools, parts, and other foreign objects from falling into the clamping area of ​​the drill bit 4, avoiding jamming during the next start-up. When the drill bit 4 is in operation, it provides proximity isolation: the movement of the drill bit 4 drives the slide 11 to move, causing the slide... The slide 11 moves along the inner wall of the guide rail 10. The movement of the slide 11 will drive the connecting rod 16 to move. The force on the connecting rod 16 will also generate a force at the connection point with the baffle 13, causing the baffle 13 to gradually rotate outward along the connecting rod 12. At the same time as the baffle 13 rotates, it will also drive the connecting frame 14 to move. The movement of the connecting frame 14 will drive the protective sleeve 15 to move, so that the protective sleeve 15 will unfold synchronously during drilling, forming a protective barrier around the drill bit 4. This physically restricts personnel's hands and clothing from approaching the cutting area, eliminating the risk of being caught in the high-speed rotation of the drill bit 4 and the shaking of the workpiece during processing. At the same time as the slide 11 moves, it will also drive the rack rod 17 to move. The movement of the rack rod 17 will cause the gear 18 to rotate through the meshing rack. Example 2

[0025] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the hydraulic tapping combined processing device for pressurized pipes further includes a clamping device. The combined processing device also includes a clamping device mounted on the base 1, a left fixing mechanism mounted on the sliding seat 23, and at least one right fixing mechanism spaced apart from the left fixing mechanism, for clamping and fixing the pipe. The clamping device includes a mounting block 20 mounted on the base 1 and a servo motor 21 mounted on the mounting block 20. A reciprocating screw 22 and a sliding seat 23 mounted on the reciprocating screw 22 are mounted on the extension end of the servo motor 21 for realizing the step-by-step supply of the pipe. The left and right fixing mechanisms each include a sliding rod 24 mounted on the sliding seat 23, a clamping pad 26 mounted on the sliding rod 24 for fixing the pipe, and a first spring 25 set between the clamping pad 26 and the sliding seat 23. The front side of the clamping pad 26 is set as an inclined surface. By utilizing the wedge-shaped force amplification and displacement compensation characteristics of the inclined surface, it is not necessary to change special clamps for different pipe diameters, which greatly reduces the tooling switching cost and is especially suitable for batch drilling operations of multi-specification pipes.

[0026] The clamping device also includes a limiting mechanism mounted on the mounting block 20. The limiting mechanism includes a hollow block 27 mounted on the sliding rod 24 for automatically releasing the clamped state of the pipe, and a limiting plate 28 mounted on the mounting block 20 for limiting the maximum moving distance and maximum thickness of the pipe. The inner wall of the hollow block 27 is provided with an inclined groove.

[0027] The clamping device also includes a drive mechanism and a cleaning mechanism mounted on the base 1. The drive mechanism includes a servo motor 29 and a cylinder 210 mounted on the extension end of the servo motor 29. The extension end of the cylinder 210 has a groove, so that the limit of the extension end of the cylinder 210 will be released synchronously only after the drill 4 starts cutting and enters the working stroke. When the drill 4 is not working, the extension end of the cylinder 210 is forcibly locked in the retracted position, which can prevent the cylinder 210 from malfunctioning. The cleaning mechanism includes a prism plate 211 installed on the extension end of the cylinder 210. The prism plate 211 is equipped with a brush for contacting the inner wall of the pipe to clean impurities and avoid subsequent process failures caused by debris residue.

[0028] The clamping device also includes a limiting mechanism installed on the cleaning mechanism to limit the extension and retraction of the cylinder 210, including a hollow rod 212 installed on the limiting plate 28 and a limiting rod 213 installed in the hollow rod 212. A second spring is provided between the hollow rods 212 to drive the limiting rod 213 to reset. A rack that meshes with the gear 18 is provided on the hollow rod 212. The bottom of the limiting rod 213 is set as an inclined surface.

[0029] In this embodiment, during operation: when the operator fixes the pipe, they insert clamping pads 26 on both sides, causing the outer wall of the pipe to first contact the inclined surface of the clamping pads 26. This causes the clamping pads 26 to be stressed, driving the sliding rods 24 to move in opposite directions, while simultaneously compressing the first spring 25 at their respective positions. Finally, after the pipe is fully inserted, the first spring 25 returns to its original position, causing the clamping pads 26 on both sides to clamp the outer wall of the pipe. Utilizing the wedge-shaped force amplification and displacement compensation characteristics of the inclined surface, it eliminates the need to change special clamps for different pipe diameters, significantly reducing tooling switching costs. This is especially suitable for batch drilling operations of multiple pipe specifications. Subsequently, the extension end of the servo motor 21 rotates to drive the reciprocating screw 22 to rotate. The rotation mechanism 22, through its inherent characteristics, allows the sliding seat 23 to move back and forth. This movement of the sliding seat 23, in turn, moves the clamping pads 26 on both sides, thus moving the pipe and enabling step-by-step drilling. Simultaneously, the sliding rod 24 moves the hollow block 27. After drilling, debris may remain on the inner wall of the pipe. At this point, the extension end of the cylinder 210 extends and moves the prismatic plate 211. The extension end of the servo motor 29 rotates, driving the fixed end of the cylinder 210 to rotate as well. This extension movement causes the brushes on the surface of the prismatic plate 211 to penetrate deep into the inner wall of the pipe, conforming to the wall at the drilling location. The rotational motion generates a circumferential brushing force. It can not only remove loose debris adhering to the pipe wall surface, but also scrape off stubborn metal shavings and plastic burrs adhering to the hole wall, avoiding subsequent process failures caused by debris residue. When the cylinder 210 is idle, it is restricted by inserting the non-sloping surface of the hollow rod 212 into the groove at the extension end of the cylinder 210, preventing the cylinder 210 from extending. When the drill bit 4 is working, that is, when the rack rod 17 moves downward, the rotation of the gear 18 meshes with the rack in the hollow rod 212, causing the hollow rod 212 to move upward. The movement of the hollow rod 212 will drive the limit rod 213 to move, causing the limit rod 213 to disengage from the groove. At this time, the extension end of the cylinder 210 can extend normally, so that it can only be extended when the drill bit 4 starts cutting. Once the working stroke begins, the limit switch at the extension end of cylinder 210 will be released simultaneously. When the drill bit 4 is not in operation, the extension end of cylinder 210 is forcibly locked in the retracted position, which can prevent cylinder 210 from malfunctioning. For example, if cylinder 210 extends prematurely before the drill bit 4 contacts the pipe, it may cause the brush to collide with the drill bit 4 and the pipe end face, or cause the mechanism to jam due to the overlap of the cleaning and drilling processes. When cylinder 210 retracts, its outer wall first contacts the inclined surface of the limit rod 213, causing the limit rod 213 to move upward under force and compress the second spring at the same time. When the groove overlaps with the limit rod 213, the second spring resets the limit rod 213 and inserts it into the groove, thus re-limiting the extension end of cylinder 210. Example 3

[0030] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the hydraulic tapping combined processing device for pressurized pipes further includes a post-processing device. The combined processing device also includes a post-processing device installed on the base 1, which is used to collect the output and residue of the pipe after tapping. The post-processing device includes a chute 30 opened on the base 1 and a slide plate 31 that matches the chute 30. A fence frame 32 is installed on the chute 30, and a pull rod 33 for driving the slide plate 31 to move is installed on the slide plate 31. A pressure plate 34 for squeezing debris is slidably installed on the fence frame 32, so that the volume of debris is compressed, greatly increasing the single capacity of the fence frame 32, and avoiding debris dispersion that makes it difficult to clean. A rubber rod 35 that can be bent by thrust is provided on the top of the pressure plate 34.

[0031] The post-processing device also includes a mounting pad 36 installed on the sliding seat 23, a guide rod 37 installed on the mounting block 20, and a guide plate 38 installed on the mounting pad 36 to prevent debris from contacting the reciprocating screw 22. The guide plate 38 is pulled by the guide rod 37.

[0032] The post-processing device also includes a touch rod 39 mounted on the guide plate 38 and a release rod 310 mounted on the base 1 for releasing the pipe from the clamped state, so that no manual force is required, greatly reducing the operating burden, and is especially suitable for high-frequency, long-term continuous operation scenarios.

[0033] In this embodiment, during operation: the movement of the sliding seat 23 drives the movement of the mounting pad 36, which in turn drives the movement of the guide plate 38. This ensures that the guide plate 38 fully covers the reciprocating lead screw 22, guiding the cutting debris to both sides of the lead screw 22 for directional collection. This limits the debris's path, preventing it from splashing onto the ground or around the equipment, and completely preventing debris from falling into the screw thread clearance. This also prevents debris from mixing with lubricating grease to form sludge, reducing friction and wear on the lead screw and the risk of jamming, extending the lead screw's feed accuracy and service life. The debris eventually falls onto the sliding plate 31 in the fence frame 32. The movement of the guide plate 38 synchronously drives the contact rod 39 to move, causing it to contact the rubber rod 35, thus... The movement of the rubber rod 35 drives the pressure plate 34 to move. The movement of the pressure plate 34 will compact the loose debris into blocks, compressing the volume of the debris and greatly increasing the single-time capacity of the fence frame 32. This prevents the debris from being scattered and difficult to clean. By manually pulling the lever 33, the slide plate 31 moves along the slide groove 30, causing the debris base 1 to fall out from below. When the sliding seat 23 resets, the hollow block 27 moves, and finally the inclined groove opened on the inner wall is released from the release lever 310. The hollow block 27 is then forced to move outward and is simultaneously released from the clamping state. At this time, the pipe will fall onto the placement pad 36, and the staff can take out the pipe normally. This eliminates the need for manual force and greatly reduces the operational burden, making it especially suitable for high-frequency, long-term continuous operation scenarios. Example 4

[0034] Based on Examples 1, 2, and 3, the process of the hydraulic tapping assembly for pressurized pipes provided in this embodiment includes the following steps: Step 1: After the workers have fixed the pipe, the slide block 3 is moved downward along the track rod 2 by hydraulic means. The movement of the slide block 3 drives the drill bit 4 to move. The drill bit 4 converts the rotational power into cutting force by electric power to complete the pipe drilling. Step 2: When the drill bit 4 is not in operation, the protective sleeves 15 on both sides are closed to form a closed cover, completely covering the high-speed rotating parts and preventing the operator from accidentally touching, cleaning or adjusting the cutting edge of the drill bit 4. Step 3: Preventing proximity and isolation when drill bit 4 is in working state: The movement of drill bit 4 drives the slide 11 to move, so that the slide 11 moves along the inner wall of guide rail frame 10. The movement of slide 11 will drive the connecting rod 16 to move. The force on the connecting rod 16 will also generate force at the connection point with the baffle 13, so that the baffle 13 will gradually rotate outward along the connecting rod 12. At the same time as the baffle 13 rotates, it will also drive the connecting frame 14 to move. The movement of the connecting frame 14 will drive the protective sleeve 15 to move, so that the protective sleeve 15 will unfold synchronously during drilling, forming a protective barrier around drill bit 4.

10. A process for a hydraulic tapping assembly for pressurized pipes, characterized in that, The hydraulic tapping assembly for pressurized pipes, as described in any one of claims 1-9, comprises the following steps: Step 1: After the workers have fixed the pipe, the slide block (3) is moved downward along the track rod (2) by hydraulic means. The movement of the slide block (3) drives the drill bit (4) to move. The drill bit (4) converts the rotational power into cutting force by electric power to complete the pipe drilling. Step 2: When the drill bit (4) is not in operation, the protective sleeves (15) on both sides are closed to form a closed cover, completely covering the high-speed rotating parts and preventing the operator from accidentally touching, cleaning or adjusting the cutting edge of the drill bit (4). Step 3: When the drill bit (4) is in working condition, prevent it from getting too close to the isolation: the movement of the drill bit (4) drives the slide (11) to move, so that the slide (11) moves along the inner wall of the guide rail frame (10). The movement of the slide (11) will drive the connecting rod (16) to move. The force on the connecting rod (16) will also generate force at the connection point with the baffle (13), so that the baffle (13) will gradually rotate outward along the connecting rod (12). While the baffle (13) is rotating, it will also drive the connecting frame (14) to move. The movement of the connecting frame (14) will drive the protective sleeve (15) to move, so that the protective sleeve (15) will unfold synchronously when drilling, forming a protective barrier around the drill bit 4.
