Description

Technical Field

[0001] This invention relates to the field of valve body flange processing technology, specifically to an integrated drilling and tapping device for valve body flanges. Background Technology

[0002] As a critical connecting component in a piping system, the machining accuracy and efficiency of valve body flanges directly affect sealing performance and system reliability. Traditionally, the drilling and tapping processes for valve body flanges are typically divided into two independent stages.

[0003] However, existing integrated drilling and tapping equipment for valve body flanges still has the following problems:

[0004] 1. When drilling through holes, blind holes and tapping the valve body, the existing device needs to switch the valve body to different processing equipment. This not only requires repeated positioning, which is prone to errors, but also reduces work efficiency.

[0005] 2. When the existing equipment switches the drilling and tapping angle for different positions on the valve body, it needs to be switched manually. This is not only inefficient, but also prone to errors because manual switching requires recalibration.

[0006] 3. When tapping the blind hole in the valve body, the existing device does not easily clean the debris inside the blind hole, which can easily lead to unqualified tapping quality. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an integrated valve body flange drilling and tapping device. This device primarily solves the problem of manually switching valve bodies when they need to be installed on different processing equipment, requiring repeated positioning, and when drilling and tapping different positions on the valve body at different angles. Manual switching necessitates recalibration, which can easily lead to errors.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0017] Compared with the prior art, the present invention provides an integrated drilling and tapping device for valve body flanges, which has the following beneficial effects:

[0018] 1. This invention integrates vertical drilling, horizontal drilling, tapping, flipping, chip removal, slag removal and tool cleaning into one machine, and completes the processing of multiple surfaces and types of holes in the valve body in one go within the protective cover. This eliminates the time waste caused by traditional multiple machines and multiple clamping, and greatly improves the overall processing efficiency.

[0019] 2. This invention uses the interference fit of the limiting post to position the through hole end of the valve body, and coordinates with the positioning plate, servo motor drive and electromagnetic lock indexing positioning to ensure that the valve body always maintains a strict coaxial axis during rotation and subsequent fixed-axis flipping. This is crucial to ensuring the coaxiality of the through holes at both ends of the valve body and the position accuracy of the blind hole.

[0020] 3. The present invention uses a flipping mechanism to automatically grab the valve body and flip it precisely 180 degrees. The flipping allows the through hole at the other end of the valve body to be accurately put back onto the limiting post, ensuring that the through holes at both ends are drilled on the same straight line, thus solving the positioning error problem caused by manual flipping.

[0021] 4. This invention uses multiple winding brushes driven by a motor and gears to simultaneously insert into and rotate in blind holes, effectively rolling out fine, entangled iron filings inside the holes, solving the problem of difficult iron filings removal in deep blind holes. Then, a tilting air gun assembly driven by a servo motor uses directional and oscillating compressed air flow to efficiently blow out fine debris and dust remaining at the bottom and sidewalls of the blind hole, resulting in more thorough cleaning, improved hole wall quality, and reliability of subsequent tapping.

[0022] 5. The present invention uses a bristle brush located above the tapping drill bit to automatically scrape off the adhering debris when it retracts after each tapping operation. The oil injection pipe then automatically sprays oil to lubricate the surface of the drill bit. This effectively prevents debris accumulation from causing tapping jamming and poor thread quality, and reduces drill bit wear, extending its service life.

[0023] 6. The present invention uses a first air gun to blow away the machined surface of the valve body in real time during drilling to prevent accumulated debris from affecting the machining accuracy and surface quality.

[0024] 7. This invention employs a high-precision ball screw linear module to drive the drill bit and tapping unit, combined with an XY-axis moving platform to precisely position the valve body, ensuring hole position accuracy. The fixed-axis rotation and flipping mechanism ensures a unified reference for multi-faceted and multi-hole drilling and cutting. Automated tool setting and program control reduce dimensional deviations caused by human factors, and effective and timely chip removal avoids secondary interference from chips in the machining process. These measures together ensure a high degree of consistency in valve body dimensions and geometric tolerances in mass production, achieving automated manufacturing. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] Please see Figures 1-12 As shown, an integrated drilling and tapping device for valve body flanges includes a support 1, a protective cover 11 mounted above the support 1, and an XY-axis moving platform 12 mounted inside the protective cover 11. The protective cover 11 houses an integrated drilling and tapping assembly 2 for drilling and tapping the valve body. The integrated drilling and tapping assembly 2 includes a vertical drilling mechanism for drilling through holes at both ends of the valve body along the same axis, and a horizontal drilling mechanism for drilling blind holes on the valve body surface. The protective cover 11 has a transverse tapping mechanism for tapping holes. Inside the protective cover 11, there is a fixed axis adjustment component 3 that keeps the valve body rotating on the same axis. The fixed axis adjustment component 3 includes a rotation mechanism that makes the valve body rotate vertically along the same axis, and a flipping mechanism that makes the valve body flip around the same axis. Inside the protective cover 11, there is a chip cleaning component 7 for cleaning long and thin iron filings inside the blind hole, and a slag cleaning component 8 for cleaning small debris inside the blind hole. Inside the protective cover 11, there is a cleaning mechanism.

[0042] To address the technical challenge of integrated drilling and tapping of the valve body, this invention employs a vertical drilling mechanism comprising a first positioning frame 21 bolted to the inside of a protective cover 11. A first ball screw linear module 22 is mounted on the side of the first positioning frame 21 facing inwards from the protective cover 11. The screw inside the first ball screw linear module 22 is threadedly connected to a first support frame 23 via a threaded cylinder. The first support frame 23 is slidably connected to the slide rail of the first ball screw linear module 22. A first motor drive module 24 is mounted inside the first support frame 23. A first drill bit 25 is held in a self-locking chuck inside the first motor drive module 24. The transverse drilling and tapping mechanisms include two second positioning frames 26 symmetrically bolted to the inside of the protective cover 11, with the two second positioning frames 26 located on opposite sides of the first positioning frame 21. A second ball screw linear module 27 is mounted on the adjacent side of each of the two second positioning frames 26. The lead screw inside group 27 is threadedly connected to the second support frame 28. The second support frame 28 is equipped with a second motor drive module 29. One of the self-locking chucks inside the second motor drive module 29 holds a second drill bit 211, and the other self-locking chuck holds a tapping drill bit 210. When it is necessary to drill and tap the valve body, the valve body is placed inside the protective cover 11. The motor inside the first ball screw linear module 22 is started, which causes the first support frame 23 to drive the first motor drive module 24 to move. Then, the motor inside the first motor drive module 24 is started, which causes the first drill bit 25 to rotate. Then, the valve body is moved accordingly by starting the XY axis moving platform 12, which allows the first drill bit 25 to be positioned at the valve body axis and achieve tool setting. After tool setting, the first drill bit 25 and the valve body are moved to a suitable position. Then, the programmed program is used to start it, which allows the first drill bit 25 to drill through holes on the surface of the valve body.

[0043] When it is necessary to drill blind holes on the valve body surface, the side to be drilled faces the second drill bit 211. Then, by starting the motor inside the second ball screw linear module 27, the second drill bit 211 moves up and down. In conjunction with the movement of the XY axis moving platform 12, the center point of the valve body to be drilled is found, and the tool is set. After the tool is set, the second drill bit 211 and the valve body are moved to a suitable position. Then, the programmed program is used to start it, so that the second drill bit 211 can drill blind holes on the valve body surface.

[0044] When tapping is required on the valve body, since the second drill bit 211 and the tapping drill bit 210 are opposite each other, after the blind hole surface of the valve body is facing the tapping drill bit 210, the position of the tapping drill bit 210 can be calculated based on the value given by the second drill bit 211. Then, the valve body is moved to the zero position again by the XY axis moving platform 12, and then it is started by the programmed program, so that the tapping drill bit 210 can tap the valve body surface.

[0045] This enables the integrated operation of drilling through holes, blind holes, and tapping in the valve body.

[0046] To address the technical problem of valve body rotating along the same axis, the present invention employs a rotating mechanism comprising a positioning plate 31 bolted to the top surface of the XY-axis moving platform 12. A first servo motor 32 is installed inside the positioning plate 31. The output shaft of the first servo motor 32 is bolted to a positioning disk 33, which is rotatably connected to the positioning plate 31 via bearings. A second electromagnetic lock 317 is mounted on the top surface of the positioning plate 31. Four positioning holes are evenly distributed on the bottom surface of the positioning disk 33. The output shaft of the second electromagnetic lock 317 corresponds to the positioning holes. A limit post 34 is bolted to the top surface of the positioning disk 33, and the limit post 34 is aligned with the inner end of the through hole of the valve body. With an interference fit, when the valve body needs to be placed, the end of the valve body with the pre-drilled through hole is fitted onto the surface of the limiting post 34, and the valve body is positioned by the limiting post 34. When it is necessary to make the blind hole surface of the valve body rotate on a fixed axis, the first servo motor 32 is connected to an external power source and then started. The first servo motor 32 will drive the positioning plate 33 to rotate. The valve body placed on the surface of the positioning plate 33 will be rotated by the positioning plate 33 and the limiting post 34, thus realizing the fixed axis rotation of the blind hole surface of the valve body. Every time the blind hole surface of the valve body rotates 90 degrees, the second electromagnetic lock 317 will be connected to an external power source and started. The output shaft of the second electromagnetic lock 317 will be inserted into the interior of the positioning hole, thereby realizing the positioning of the valve body.

[0047] To address the technical problem of valve body flipping along the same axis, the present invention employs a flipping mechanism comprising a second cylinder 315 mounted on the top surface of a positioning plate 31. The output shaft of the second cylinder 315 is fixedly connected to a first limiting plate 316. A second servo motor 35 is mounted on the top surface of the first limiting plate 316. The output shaft of the second servo motor 35 is fixedly connected to a lead screw via a coupling, and the lead screw is threadedly connected to a linkage plate 36 via a threaded cylinder. A first cylinder 314 is mounted on the side of the linkage plate 36 facing the valve body. The output shaft of the first cylinder 314 is fixedly connected to the linkage plate 36. A rotary cylinder 37 is mounted on the side of the linkage plate 36 away from the first cylinder 314. A pressing column 311 is fixedly connected to the output end of the rotary cylinder 37. The surface of the pressing column 311 is uniformly open... The system includes several sliding grooves, each with a slidingly connected extrusion block 312. Each extrusion block 312 has a fixedly connected limit block 313 on its surface. A first rotating plate 39 is rotatably connected to the interior of the linkage plate 36 via bolts. A limit cylinder 310 is threadedly connected to the end of the first rotating plate 39 away from the rotating cylinder 37. Positioning grooves are provided on the surface of the limit cylinder 310 at positions corresponding to the limit blocks 313, and the limit blocks 313 are slidably connected to the limit cylinder 310 through these grooves. A first electromagnetic lock 38 is installed on the side of the linkage plate 36 facing the first rotating plate 39. Two positioning holes are symmetrically provided on the side of the first rotating plate 39 facing the first electromagnetic lock 38. The output shaft of the first electromagnetic lock 38 is inserted into the positioning holes. When needed... When the valve body through-hole surface is rotated on a fixed axis, the second servo motor 35 is connected to an external power source and started. The linkage plate 36 moves towards the valve body due to the rotation of the lead screw until the extrusion column 311, carrying the extrusion block 312, is inserted into the valve body. Then, the first cylinder 314 is connected to an external air pump and started. The output shaft of the first cylinder 314 drives the linkage plate 36 to move away from the valve body, indirectly driving the extrusion column 311 to move away from the valve body. Due to the difference in shape between the extrusion column 311 and the extrusion block 312, and the limitation of the limiting block 313 by the limiting cylinder 310, when the extrusion column 311 moves, several extrusion blocks 312 expand outward and fit against the inner wall of the valve body. The valve body is positioned by friction. When it is necessary to rotate the valve... When the valve body is in operation, the second cylinder 315 is connected to an external air pump and started. The first limit plate 316 will indirectly drive the valve body to move upward until the valve body is separated from the positioning plate 33. Then, the rotary cylinder 37 is connected to an external air pump and started. The rotary cylinder 37 will drive the first rotating plate 39 to rotate inside the linkage plate 36. At the same time, the valve body will be rotated 180 degrees through the pressing block 312. After the rotation is completed, the first electromagnetic lock 38 is connected to an external power supply and started. The output shaft of the first electromagnetic lock 38 will be inserted into the positioning hole to lock the first rotating plate 39, thus realizing the fixed axis rotation of the valve body. Then, the output shaft of the second servo motor 35 is retracted, and the valve body will be sleeved on the surface of the limit post 34 again, so that a coaxial through hole can be drilled at the other end of the valve body.

[0048] To address the technical problem of cleaning debris inside the blind hole of the valve body, the present invention employs a debris removal assembly 7, which includes a mounting bracket 71 disposed inside the support 1. The mounting bracket 71 is fixedly connected to the second support bracket 28 on the left side by bolts. The second support bracket 28 is slidably connected to the slide rail of the second ball screw linear module 27 on the left side via a slider. A first electric push rod 77 is mounted on the surface of the mounting bracket 71. The output shaft of the first electric push rod 77 is fixedly connected to a movable plate 72. The movable plate 72 is slidably connected to the mounting bracket 71 via a guide rail. A third motor 73 is mounted inside the movable plate 72 by bolts. A first gear 74 is mounted on the output shaft of the third motor 73. The first gear 74 is rotatably connected to the movable plate 72 via a bearing. The surface of the first gear 74 meshes with… The assembly includes several second gears 75 connected together, which are rotatably connected to a movable plate 72 via bearings. Each second gear 75 has a winding brush 76 fixedly connected inside by bolts, and the winding brush 76 corresponds to a blind hole in the valve body. The slag removal assembly 8 includes a second electric push rod 85 mounted on the top surface of the positioning plate 31. The output shaft of the second electric push rod 85 is fixedly connected to a second limiting plate 81, which is slidably connected to the positioning plate 31 via a guide rail. A servo motor 83 is mounted on the surface of the second limiting plate 81, and the output shaft of the servo motor 83 is fixedly connected to a second rotating plate 82. The second rotating plate 82 is rotatably connected to the second limiting plate 81 via bearings. Several second air guns 84 are evenly mounted on the surface of the second rotating plate 82, and the second air guns 84 are... An external air pump is connected, and each second air gun 84 is tilted. To avoid iron filings remaining inside the blind holes after machining, after the blind holes are machined, the screw inside the second ball screw linear module 27 rotates, driving the mounting frame 71 upward through the second support frame 28 until several winding brushes 76 correspond to several blind holes. Then, the valve body is moved towards the winding brushes 76 through the XY axis moving platform 12 until it reaches a suitable position. Then, the mounting frame 71 is connected to an external power source and started. The movable plate 72 drives the winding brushes 76 to insert into the blind holes. Then, the third motor 73 is connected to an external power source and started. The first gear 74 drives several winding brushes 76 to rotate inside the blind holes through the second gear 75. The rotation of the winding brush 76 can coil up the fine iron filings inside the blind hole. Then, by pulling out the winding brush 76, the iron filings inside the blind hole are cleaned. Then, the valve body is rotated 90 degrees so that the blind hole surface is in a direction away from the extrusion column 311. Then, the second electric push rod 85 is connected to an external power source and started. The second limit plate 81 will move towards the blind hole surface until the second air gun 84 corresponds to the blind hole. Then, the second air gun 84 is connected to an external air pump and started. The second air gun 84 will spray air into the blind hole at an angle, causing the fine debris remaining inside the blind hole to be blown out. Then, the servo motor 83 is connected to an external power source, causing the second rotating plate 82 to drive the second air gun 84 to swing. The airflow fluctuation can make it easier to discharge the debris.

[0049] To address the technical problem of cleaning the valve body surface and the tapping drill surface, the cleaning mechanism employed in this invention includes a first air gun 4 mounted on the bottom surface of the first support frame 23. The input pipe of the first air gun 4 is connected to an external air pump, and the output end of the first air gun 4 faces the first drill bit 25. It also includes a bristle brush 6 fixedly connected to the surface of the second positioning frame 26 on the right side via a connecting frame. The bristle brush 6 is located above the tapping drill bit 210. Furthermore, it includes an oil injection pipe 5 mounted on the surface of the second support frame 28. The input pipe of the oil injection pipe 5 is connected to an external oil injection box, and the output end of the oil injection pipe 5 faces the tapping drill bit 210. When the first drill bit 25 drills a through hole, the first air gun 4 is connected to the external air pump, and the first air gun 4 removes debris falling onto the valve body surface, as surface debris affects processing quality.

[0050] When tapping the valve body, after each tapping operation, the tapping drill bit 210 moves upward and comes into contact with the bristle brush 6. The bristle brush 6 cleans away the debris adhering to the surface of the tapping drill bit 210. After cleaning, the tapping drill bit 210 returns to its original position. Then, the oil injection pipe 5 is connected to the external oil injection box, and lubricating oil is sprayed onto the surface of the tapping drill bit 210 through the oil injection pipe 5, making it less likely for the tapping drill bit 210 to get stuck during tapping.

[0051] The present invention is used in the following steps:

[0052] S1: When it is necessary to place the valve body, the end of the valve body with the pre-drilled hole is fitted onto the surface of the limiting post 34. The valve body is positioned by the limiting post 34. When it is necessary to make the blind hole surface of the valve body rotate on a fixed axis, the first servo motor 32 is connected to an external power source and then started. The first servo motor 32 will drive the positioning plate 33 to rotate. The valve body placed on the surface of the positioning plate 33 will be rotated by the positioning plate 33 and the limiting post 34, thus realizing the fixed axis rotation of the blind hole surface of the valve body. Whenever the blind hole surface of the valve body rotates 90 degrees, the second electromagnetic lock 317 will be connected to an external power source and started. The output shaft of the second electromagnetic lock 317 will be inserted into the interior of the positioning hole, thereby realizing the positioning of the valve body.

[0053] S2: When it is necessary to drill and tap the valve body, the valve body is placed inside the protective cover 11. The motor inside the first ball screw linear module 22 is started, which causes the first support frame 23 to drive the first motor drive module 24 to move. Then, the motor inside the first motor drive module 24 is started, which causes the first drill bit 25 to rotate. Then, the valve body is moved accordingly by starting the XY axis moving platform 12, which allows the first drill bit 25 to be positioned at the valve body axis and achieve tool setting. After tool setting is completed, the first drill bit 25 and the valve body are moved to a suitable position. Then, the programmed program is used to start it, which allows the first drill bit 25 to drill through holes on the surface of the valve body.

[0054] S3: When it is necessary to rotate the valve body through hole surface in a fixed-axis manner, the second servo motor 35 is connected to an external power source and started. The linkage plate 36 will move towards the valve body due to the rotation of the lead screw until the extrusion column 311, carrying the extrusion block 312, is inserted into the valve body. Then, the first cylinder 314 is connected to an external air pump and started. The output shaft of the first cylinder 314 will drive the linkage plate 36 to move away from the valve body, indirectly driving the extrusion column 311 to move away from the valve body. Due to the difference in shape between the extrusion column 311 and the extrusion block 312, and the limitation of the limiting block 313 by the limiting cylinder 310, when the extrusion column 311 moves, several extrusion blocks 312 will expand outward and fit against the inner wall of the valve body. The valve body is positioned by friction. When the valve body is rotated, the second cylinder 315 is connected to an external air pump and started. The first limit plate 316 indirectly drives the valve body to move upward until the valve body disengages from the positioning plate 33. Then, the rotary cylinder 37 is connected to an external air pump and started. The rotary cylinder 37 drives the first rotating plate 39 to rotate inside the linkage plate 36. At the same time, the pressing block 312 drives the valve body to rotate 180 degrees. After the rotation is completed, the first electromagnetic lock 38 is connected to an external power source and started. The output shaft of the first electromagnetic lock 38 is inserted into the positioning hole to lock the first rotating plate 39, thus achieving the fixed-axis rotation of the valve body. Then, the output shaft of the second servo motor 35 is retracted, and the valve body is once again fitted onto the surface of the limit post 34. A coaxial through hole can then be drilled at the other end of the valve body.

[0055] S4: When it is necessary to drill a blind hole on the surface of the valve body, the side to be drilled faces the second drill bit 211. Then, the motor inside the second ball screw linear module 27 is started to make the second drill bit 211 move up and down. In conjunction with the movement of the XY axis moving platform 12, the center point of the valve body to be drilled is found to achieve tool setting. After tool setting is completed, the second drill bit 211 and the valve body are moved to a suitable position. Then, the programmed program is used to start it, so that the second drill bit 211 can drill a blind hole on the surface of the valve body.

[0056] S5: When tapping the valve body is required, since the second drill bit 211 and the tapping drill bit 210 are opposite each other, after the blind hole surface of the valve body faces the tapping drill bit 210, the position of the tapping drill bit 210 can be calculated according to the value given by the second drill bit 211. Then, the valve body is moved to the zero position again by the XY axis moving platform 12, and then it is started by the programmed program, so that the tapping drill bit 210 can tap the surface of the valve body.

[0057] S6: To avoid residual iron filings inside the blind holes after machining, after the blind holes are machined, the screw inside the second ball screw linear module 27 rotates, driving the mounting frame 71 upward through the second support frame 28 until several winding brushes 76 correspond to several blind holes. Then, the valve body is moved towards the winding brushes 76 through the XY axis moving platform 12 until it reaches a suitable position. The mounting frame 71 is then connected to an external power source and started. The movable plate 72 drives the winding brushes 76 to insert into the blind holes. Then, the third motor 73 is connected to an external power source and started. The first gear 74 drives several winding brushes 76 to rotate inside the blind holes through the second gear 75. The rotation of the winding brushes 76... The process involves winding up the fine iron filings inside the blind hole, then removing the winding brush 76 to clean the iron filings inside the blind hole. Next, the valve body is rotated 90 degrees so that the blind hole surface is located away from the extrusion column 311. Then, the second electric push rod 85 is connected to an external power source and started. The second limit plate 81 moves towards the blind hole surface until the second air gun 84 corresponds to the blind hole. Then, the second air gun 84 is connected to an external air pump and started. The second air gun 84 sprays air into the blind hole at an angle, blowing out the fine debris remaining inside the blind hole. Then, the servo motor 83 is connected to an external power source, causing the second rotating plate 82 to drive the second air gun 84 to swing. The fluctuation of the airflow makes it easier to discharge the debris.

[0058] S7: When the first drill bit 25 drills through the hole, the first air gun 4 is connected to an external air pump. The first air gun 4 drops the debris that falls on the surface of the valve body. The surface debris affects the processing quality.

[0059] S8: When tapping the valve body, after each tapping operation, the tapping drill bit 210 moves upward and comes into contact with the bristle brush 6. The bristle brush 6 cleans away the debris stuck to the surface of the tapping drill bit 210. After cleaning, the tapping drill bit 210 returns to its original position. Then, the oil injection pipe 5 is connected to the external oil injection box, and lubricating oil is sprayed onto the surface of the tapping drill bit 210 through the oil injection pipe 5, making it less likely for the tapping drill bit 210 to get stuck during tapping.
