Description

Technical Field

[0001] This invention relates to the field of valve body manufacturing and processing, and more specifically, to a valve body assembly processing equipment. Background Technology

[0002] Currently, in the intelligent manufacturing equipment industry, the assembly of valve bodies is crucial. In the processing of the valve body flange end, drilling, grinding, and tapping are three critical processes. In existing valve body processing technology, the three processing tools of drill bit, grinding head, and tap cannot usually be integrated into one processing equipment. This means that after each process is completed, the valve body needs to be moved from the current processing station to another dedicated processing station for the next process. This not only reduces work efficiency but also causes burrs to cool and solidify during the valve body transfer process.

[0003] A search revealed that Chinese patent CN118875733B discloses an integrated drilling and tapping device and method for butterfly valve body machining. This patent includes a worktable, a control panel, and a butterfly valve body. The worktable has machining components and a moving component, which can reduce tool changing and workpiece repositioning time. However, this patent requires the valve body to be transferred via the moving component between drilling and tapping. Although the transfer process is automated, it still requires a relatively long time to wait for the valve body to be transferred. In addition, in actual flange end hole machining, in addition to drilling and tapping, the drilled hole also needs to be ground to improve the tapping quality. This patent cannot integrate multiple steps, and each additional step requires an extra valve body transfer, resulting in low overall machining efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide a valve body combination processing equipment that integrates the tools required for processing into one unit for switching use, and improves processing efficiency through unified control by a single drive source.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is to provide a valve body assembly processing equipment, comprising:

[0006] frame;

[0007] A clamping mechanism is provided in the frame, and the clamping mechanism is adapted to clamp the valve body;

[0008] The machining assembly is disposed in the frame. The machining assembly includes a linear drive mechanism, a rotary mechanism, a tool changing mechanism, and a base. At least one tool disc is rotatably mounted on the base. The tool disc is provided with a drill bit, a grinding head, and a tap.

[0009] The tool changing mechanism is mounted on the base and connected to the cutter head to drive the cutter head to rotate, thereby controlling the drill bit, the grinding head, or the tap to be switched to be coaxial with the hole to be drilled on the valve body flange end.

[0010] The rotating mechanism is connected to the base to be adapted to drive the drill bit, grinding head or tap on the cutter head that has been switched to a designated position to rotate, thereby performing corresponding processing on the area that needs to be drilled.

[0011] The linear drive mechanism is connected to the base to be adapted to drive the base closer to or away from the valve body.

[0012] Furthermore, the linear drive mechanism includes a third motor and a threaded rod. The third motor is mounted on the frame, the threaded rod is rotatably mounted on the frame, and the base is assembled on the outside of the threaded rod. The output end of the third motor is connected to the threaded rod to drive the threaded rod to rotate, thereby driving the base to move along the axial direction of the threaded rod.

[0013] The frame is provided with a slide rail corresponding to the base, and the base is slidably mounted on the slide rail.

[0014] Furthermore, the rotating mechanism includes a first motor, a first driving gear, a first driven gear corresponding to the cutter head, an electric cylinder, and a moving frame;

[0015] The drill bit, the grinding head, and the tap are all fixedly fitted with drive gears on their exteriors;

[0016] The first motor is mounted on the base, the first drive gear is rotatably mounted on the base, the output end of the first motor is connected to the first drive gear, the first driven gear is rotatably mounted on the moving frame, the first drive gear meshes with the first driven gear, and the first driven gear is adapted to mesh with one of the drive gears respectively under the drive of the tool changing mechanism;

[0017] The fixed end of the electric cylinder is mounted on the base, and the telescopic end of the electric cylinder is connected to the movable frame to drive the movable frame to move linearly, thereby causing the first driven gear to be displaced, so that the first driven gear is disengaged or engaged with the corresponding drive gear, so as to avoid the first driven gear being deflected at an angle when the tool changing mechanism drives the tool disc to rotate.

[0018] Furthermore, the tool changing mechanism includes a second motor, a second driving gear, a second driven gear, and a switching gear corresponding to the tool disc;

[0019] The switching gear is coaxially and fixedly connected to the corresponding cutter head. The second motor is mounted on the base, and the output end of the second motor is connected to the second driving gear. The second driven gear is rotatably mounted on the base. The second driving gear meshes with the second driven gear. The switching gear meshes with the second driven gear. The second motor is adapted to drive the second driving gear to rotate, thereby causing the cutter head to produce an angular offset, so that the required drill bit, grinding head, or tap rotates to be coaxially aligned with the opening position on the valve body flange end.

[0020] Furthermore, the grinding head includes an extrusion tube, a grinding disc, and at least one movable plate. The drive gear corresponding to the grinding head is fixedly sleeved on the outer circumferential surface of the extrusion tube. A fixing ring is fixedly sleeved on the outside of the extrusion tube. The extrusion tube is rotatably mounted on the cutter disc.

[0021] The grinding disc is slidably disposed outside the extrusion tube. The grinding disc has a movable groove corresponding to the moving plate. An adjusting plate is slidably disposed in the movable groove. A first spring is disposed between the adjusting plate and the movable groove. The moving plate is disposed on the corresponding adjusting plate.

[0022] The grinding disc is provided with a first grinding surface. The movable plate includes a head and a handle. The head of the movable plate is provided with a second grinding surface. The extrusion tube is provided with a first mating surface. The movable plate is provided with a second mating surface. When the grinding disc is driven by the linear drive mechanism to move towards the valve body, the first grinding surface is pressed against the outer orifice of the valve body flange end. The movable plate is driven by the linear drive mechanism to move into the corresponding hole of the flange end. The extrusion tube is driven by the linear drive mechanism to move into the corresponding hole of the flange end and presses the second mating surface through the first mating surface. This causes the movable plate to be driven to expand radially outward with the center of the extrusion tube as the axis, so that the handle of the movable plate located in the hole abuts against the hole wall, and at the same time, the second grinding surface on the head abuts against the inner orifice of the flange end.

[0023] The extrusion tube is adapted to be driven to rotate and drive the first grinding surface to grind the outer hole of the flange end, the second grinding surface to grind the inner hole of the flange end, and the handle of the moving plate to grind the hole.

[0024] Furthermore, an air pump is installed on the fixed ring, which is hollow. The air outlet of the air pump is connected to the inside of the fixed ring. An air outlet plate is provided on the outside of the extrusion tube. The air outlet plate is hollow and its inner cavity communicates with the inner cavity of the fixed ring. An air outlet hole communicating with the outside is opened on the air outlet plate. When the grinding head grinds the hole, the air outlet plate moves into the hole along with the extrusion tube. The air outlet hole is adapted to divert the gas provided by the air pump to the inside and outside of the hole after being sprayed onto the inner wall of the hole, thereby blowing the grinding debris out through the gap between the grinding disc and the extrusion tube.

[0025] Furthermore, the valve body assembly processing equipment also includes a telescopic mechanism and an oil supply assembly;

[0026] The telescopic mechanism is connected to the movable plate to be adapted to first push the movable plate away from the grinding disc when the extrusion tube extrudes the movable plate, and then to make the movable plate open outward.

[0027] The head of the movable plate is provided with a protective surface, which is adjacent to the second grinding surface. When the movable plate is pushed to move away from the grinding disc, the handle of the movable plate grinds the inner wall of the hole. After the inner wall of the hole is ground smooth and the friction between the movable plate and the inner wall of the hole is reduced, the movable plate moves towards the grinding disc under the pull of the telescopic mechanism until the second grinding surface contacts the inner opening. The second grinding surface is adapted to grind after contacting the inner opening, and moves towards the grinding disc as the burrs at the inner opening are continuously ground away, until the protective surface contacts the opening. The protective surface will not grind the opening.

[0028] The oil supply assembly is adapted to inject oil into the inner cavity of the extrusion tube. The extrusion tube has several through-holes for discharging oil from the extrusion tube into the holes.

[0029] A switch plate is slidably mounted on the outside of the extrusion tube. A fourth spring is provided between the switch plate and the fixed ring. The switch plate has several through slots that correspond to the oil outlet holes and penetrate through itself. When the switch plate is in the initial position, it is suitable to close the oil outlet holes through its non-through slot portion. A push plate is provided on the moving plate adjacent to the protective surface. When the moving plate moves toward the grinding disc, it drives the push plate to move toward the switch plate and pushes the switch plate until the grinding is completed. The switch plate is then pushed until the through slots are aligned with the corresponding oil outlet holes to open the oil outlet holes for oiling.

[0030] Furthermore, the telescopic mechanism includes a second spring, a third spring, and a roller;

[0031] The movable plate is slidably disposed on the adjusting plate, the second spring is disposed between the movable plate and the adjusting plate, the movable plate has a groove, the third spring is disposed in the groove, one end of the third spring is connected to the groove, the other end of the third spring is connected to a housing, and the roller is rotatably installed in the housing;

[0032] When the first grinding surface comes into contact with the valve body, the extrusion tube moves into the hole and extrudes the roller, causing the moving plate to extend away from the grinding disc. Then, the roller is extruded into the groove, and the first mating surface extrudes the second mating surface to drive the moving plate to expand radially.

[0033] The oil supply assembly includes a fixed pipe and an oil storage tank corresponding to the cutter head. The fixed pipe includes an oil inlet end and an oil outlet end. The fixed pipe is fixedly mounted on the corresponding cutter head. The oil outlet end of the fixed pipe is rotatably connected to the corresponding extrusion pipe through a rotary seal. The oil inlet end of the fixed pipe is coaxially arranged with the corresponding cutter head and passes through the cutter head and the corresponding switching gear. The oil inlet end of the fixed pipe is connected to the oil supply pipe of the oil storage tank through a rotary seal. The oil storage tank is mounted on the base.

[0034] Furthermore, the clamping mechanism includes a placement plate, a fourth motor, a bidirectional screw, and two clamps;

[0035] The placement plate is set on the frame, the fourth motor is mounted on the placement plate, the bidirectional screw is rotatably mounted inside the placement plate, and the two clamps are respectively assembled on the two oppositely arranged threads of the bidirectional screw. The output end of the fourth motor is connected to the bidirectional screw to drive the bidirectional screw to rotate, thereby driving the two clamps to move towards or away from each other to clamp or release the valve body.

[0036] The clamp includes a docking plate, two first clamping plates, and a second clamping plate. The docking plate is mounted on the bidirectional screw. The first clamping plates are adapted to clamp the valve body portions at the two flange ends used for pipe connection, and the second clamping plates are adapted to clamp the valve body portions at the flange end of the valve cover.

[0037] Furthermore, the placement plate is rotatably mounted on the frame, and a fifth motor is installed on the frame. The output end of the fifth motor is connected to the placement plate to drive the placement plate to shift its angle, thereby rotating and switching a flange end that needs to be processed to correspond to the position of the processing component.

[0038] By adopting the above technical solution, the present invention has the following beneficial effects:

[0039] The cutter head integrates drill bits, grinding heads, and taps, and a tool changing mechanism enables rapid switching without manual replacement or the need to transfer the valve body to another worktable. After switching, the drill bit, grinding head, or tap meshes with the first driven gear in the rotating mechanism through its corresponding drive gear. The speed and direction of rotation are uniformly controlled by the first motor. When tool switching is required, the first driven gear is displaced by an electric cylinder to prevent the first driven gear from rotating off-center during the rotation of the cutter head, which would prevent the first driven gear from properly meshing with the drive gear corresponding to the switched tool. This design allows the cutter head to integrate any tool as needed without requiring a separate drive source for each tool.

[0040] Driven by the linear drive mechanism, the first grinding surface on the grinding disc is pressed against the outer orifice of the flange end. Then, the linear drive mechanism drives the extrusion tube to move continuously into the corresponding hole. During this process, the extrusion tube extrudes the moving plate, causing the moving plate to expand radially. After expansion, the handle of the moving plate contacts the inner wall of the hole under the support of the extrusion tube, while the second grinding surface on the head of the moving plate abuts against the orifice of the inner hole of the flange end. Finally, driven by the rotation mechanism, the grinding head rotates as a whole to achieve grinding of the outer orifice of the first grinding surface and the inner orifice of the second grinding surface. The handle of the moving plate grinds the inner wall of the hole, realizing the simultaneous completion of fine grinding of the inner wall of the hole and deburring of the inner and outer orifices in a single feed. At the same time, gas is introduced into the hole through the vent and flows out to the inner and outer orifices of the hole to remove the debris left by grinding.

[0041] With the telescopic mechanism in place, the extrusion tube first pushes the moving plate to extend away from the grinding disc, then drives the moving plate to open outward, so that the handle of the moving plate abuts against the inner wall of the hole, giving priority to grinding the inner wall of the hole. After grinding, the friction between the handle and the hole wall is reduced. Under the action of the second spring, the moving plate moves towards the grinding disc, so that the second grinding surface abuts against the inner opening. As the burrs at the inner opening are removed, the moving plate stops moving towards the grinding disc. At this time, the inner opening abuts against the protective surface. The protective surface will not grind the opening. When the protective surface abuts against the opening, the grinding of the inner opening is completed. At the same time as this process is completed, the push plate squeezes the switch plate to expose the oil outlet. After grinding is completed, oil spraying is performed to avoid the mixing of grinding debris and oil affecting the subsequent tapping effect. The comprehensive grinding and oiling of both sides and inside the hole improves the stability of subsequent tapping and ensures the quality of the flange end hole. Attached Figure Description

[0058] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0059] Example 1: As Figure 1-4 As shown, a valve body assembly processing equipment includes:

[0060] Rack 1;

[0061] The clamping mechanism 3 is installed in the frame 1 and is adapted to clamp the valve body;

[0062] The machining component 2 is set in the frame 1. The machining component 2 includes a linear drive mechanism, a rotary mechanism, a tool changing mechanism and a base 21. At least one tool disc 22 is rotatably mounted on the base 21. The tool disc 22 is provided with a drill bit 23, a grinding head 24 and a tap 25.

[0063] The tool changing mechanism is set on the base 21 and connected to the cutter head 22 to drive the cutter head 22 to rotate, thereby controlling the drill bit 23 or grinding head 24 or tap 25 to be switched to be coaxial with the hole to be drilled on the valve body flange end;

[0064] The rotating mechanism is connected to the base 21 to be adapted to drive the drill bit 23, grinding head 24, or tap 25 on the cutter head 22 to rotate when switched to a designated position, so as to perform corresponding processing on the place where drilling is required.

[0065] The linear drive mechanism is connected to the base 21 to be adapted to move the base 21 closer to or away from the valve body.

[0066] like Figure 3 As shown, the linear drive mechanism includes a third motor 236 and a threaded rod 237. The third motor 236 is mounted on the frame 1, and the threaded rod 237 is rotatably mounted on the frame 1. The base 21 is assembled on the outside of the threaded rod 237. The output end of the third motor 236 is connected to the threaded rod 237 to drive the threaded rod 237 to rotate, thereby driving the base 21 to move along the axial direction of the threaded rod 237.

[0067] The frame 1 is provided with a slide rail corresponding to the base 21, and the base 21 is slidably mounted on the slide rail.

[0068] When it is necessary to control the movement of the base 21 so that the selected tool on the cutter head 22 can process the flange end of the valve body, the third motor 236 is started to drive the threaded rod 237 to rotate forward. The forward rotation of the threaded rod 237 drives the base 21 to move towards the valve body to complete the corresponding process. After the processing is completed, the third motor 236 is controlled to reverse so that the base 21 moves in the opposite direction to the reset position. The slide rail setting can prevent the base 21 from rotating under the drive of the threaded rod 237, and at the same time improve the stability of the movement of the base 21.

[0069] like Figure 4-6 As shown, the rotating mechanism includes a first motor 26, a first driving gear 27, a first driven gear 28 corresponding to the cutter head 22, an electric cylinder 211, and a moving frame 210;

[0070] The drill bit 23, the grinding head 24, and the tap 25 are all fixedly fitted with drive gears 29;

[0071] The first motor 26 is mounted on the base 21, the first drive gear 27 is rotatably mounted on the base 21, the output end of the first motor 26 is connected to the first drive gear 27, the first driven gear 28 is rotatably mounted on the moving frame 210, the first drive gear 27 meshes with the first driven gear 28, and the first driven gear 28 is adapted to mesh with one of the drive gears 29 respectively under the drive of the tool changing mechanism.

[0072] The fixed end of the electric cylinder 211 is mounted on the base 21, and the telescopic end of the electric cylinder 211 is connected to the moving frame 210 to drive the moving frame 210 to move linearly, thereby driving the first driven gear 28 to generate displacement, so that the first driven gear 28 is disengaged or engaged with the corresponding drive gear 29, so as to avoid the first driven gear 28 from being deflected at an angle when the tool changing mechanism drives the tool disc 22 to rotate.

[0073] When it is necessary to rotate the selected drill bit 23, grinding head 24, or tap 25, the first motor 26 is started to drive the first drive gear 27 to rotate. The first drive gear 27 achieves the rotation of the first driven gear 28 by meshing with the first driven gear 28. The first driven gear 28 drives the selected tool to rotate by meshing with the drive gear 29 provided on the corresponding drill bit 23, grinding head 24, or tap 25.

[0074] like Figure 4-6 As shown, the tool changing mechanism includes a second motor 212, a second driving gear 213, a second driven gear 214, and a switching gear 215 corresponding to the tool disc 22;

[0075] The switching gear 215 is coaxially and fixedly connected to the corresponding cutter head 22. The second motor 212 is mounted on the base 21. The output end of the second motor 212 is connected to the second driving gear 213. The second driven gear 214 is rotatably mounted on the base 21. The second driving gear 213 meshes with the second driven gear 214. The switching gear 215 meshes with the second driven gear 214. The second motor 212 is adapted to drive the second driving gear 213 to rotate, thereby causing the cutter head 22 to produce an angular offset, so that the required drill bit 23, grinding head 24, or tap 25 rotates to be coaxially corresponding to the opening position on the valve body flange end.

[0076] When it is necessary to switch between drill bit 23, grinding head 24, or tap 25, the second motor 212 is started to drive the second drive gear 213 to rotate. The second drive gear 213 achieves the rotation of the second driven gear 214 by meshing with the second driven gear 214. The second driven gear 214 achieves the rotation of the cutter head 22 by meshing with the switching gear 215 on each cutter head 22. The cutter head 22 produces an angular offset under rotation, thereby switching the required tool to be aligned with the opening position on the valve body flange end and performing the corresponding process.

[0077] It should be noted that before starting the second motor 212, i.e., when tool changing is required, the electric cylinder 211 should be started first to move the moving frame 210. After the moving frame 210 moves, all the first driven gears 28 are disengaged from the first driving gear 27 and the corresponding drive gear 29. In this state, the second motor 212 is started to perform the tool changing operation. After the tool changing, the electric cylinder 211 resets the first driven gears 28 and re-engages them with the first driving gear 27 and the drive gear 29 corresponding to the changed tool. The drill bit 23, grinding head 24, and tap 25 are then engaged. When the corresponding drive gear 29 switches to the position aligned with the hole, the positions of all the corresponding drive gears 29 are the same. This is to ensure that they mesh normally with the first driven gear 28 after switching. At the same time, the first driven gear 28 needs to rotate back to the initial position after each process is completed to ensure normal meshing in the future. This part can be controlled by PLC. Under this setting, multiple cutter heads 22 can be switched synchronously, and after switching, the selected cutter is rotated uniformly by the first motor 26. More required machining cutters can be integrated on the cutter head 22 without the need to add more drive sources.

[0078] The electric cylinder 211 is existing technology, and its specific structure and working principle will not be described in detail here.

[0079] Before processing the valve body, the drill bit 23 is in working condition. When processing the valve body is required, the valve body is first limited by the clamping mechanism 3. After the limit is set, the position of the hole to be drilled on the flange end of the valve body corresponds to the position of the drill bit 23 on each cutter head 22. At this time, the rotation mechanism is started first to drive the drill bit 23 to rotate, and then the linear drive mechanism is started to move the base 21 and all its components toward the valve body. The drill bit 23 is moved until it drills through the hole to be drilled. Then the linear drive mechanism is controlled to reset the base 21 and stop the rotation mechanism. At this time, the drilling process is completed. In this embodiment, the hole is a through hole on the valve body.

[0080] After drilling is completed, the electric cylinder 211 is activated to drive the first driven gear 28 to move and disengage. Then, the tool changing mechanism is activated to rotate the cutter head 22 and move the grinding head 24 to the previous drill bit 23. The electric cylinder 211 is then controlled to reset the first driven gear 28 and mesh with the drive gear 29 corresponding to the grinding head 24. After meshing, the gear 28 moves to the valve body through the linear drive mechanism and inserts the grinding head 24 into the hole. Then, the rotating mechanism is activated to drive the grinding head 24 to rotate to complete the grinding work. After grinding is completed, the gear 28 is reset through the linear drive mechanism.

[0081] Finally, switch to tap 25 to tap the hole. The tapping process is the same as drilling, except that the tap 25 rotates in opposite directions when it enters and exits the hole. This part is controlled by the rotating mechanism.

[0082] Example 2: Figure 7-12 As shown, this embodiment further includes the following structure based on embodiment one: the grinding head 24 includes a pressing tube 217, a grinding disc 218 and at least one moving plate 220, the driving gear 29 corresponding to the grinding head 24 is fixedly sleeved on the outer peripheral surface of the pressing tube 217, the pressing tube 217 is fixedly sleeved with a fixing ring 235, and the pressing tube 217 is rotatably mounted on the cutter disc 22.

[0083] The grinding disc 218 is slidably disposed outside the extrusion tube 217. The grinding disc 218 has an active groove corresponding to the moving plate 220. An adjusting plate 223 is slidably disposed in the active groove. A first spring 224 is disposed between the adjusting plate 223 and the active groove. The moving plate 220 is disposed on the corresponding adjusting plate 223.

[0084] The grinding disc 218 is provided with a first grinding surface 219, the moving plate 220 includes a head and a handle, the head of the moving plate 220 is provided with a second grinding surface 221, the extrusion tube 217 is provided with a first mating surface 225, and the moving plate 220 is provided with a second mating surface 226. When the grinding disc 218 is driven by the linear drive mechanism to move towards the valve body, the first grinding surface 219 is pressed against the outer orifice of the valve body flange end. The moving plate 220 is driven by the linear drive mechanism to move into the corresponding hole of the flange end. The extrusion tube 217 is driven by the linear drive mechanism to move into the corresponding hole of the flange end and presses the second mating surface 226 through the first mating surface 225, thereby driving the moving plate 220 to expand radially outward with the center of the extrusion tube 217 as the axis, so that the handle of the moving plate 220 located in the hole abuts against the hole wall, and at the same time, the second grinding surface 221 on the head abuts against the inner orifice of the flange end.

[0085] The extrusion tube 217 is adapted to be driven to rotate and drive the first grinding surface 219 to grind the outer hole of the flange end, the second grinding surface 221 to grind the inner hole of the flange end, and the handle of the moving plate 220 to grind the hole.

[0086] like Figure 8 , Figure 13 As shown, an air pump 230 is installed on the fixed ring 235. The fixed ring 235 is hollow. The air outlet of the air pump 230 is connected to the inside of the fixed ring 235. An air outlet plate 231 is provided on the outside of the extrusion tube 217. The air outlet plate 231 is hollow. The inner cavity of the air outlet plate 231 is connected to the inner cavity of the fixed ring 235. An air outlet hole 232 communicating with the outside is opened on the air outlet plate 231. When the grinding head 24 grinds the hole, the air outlet plate 231 moves into the hole along with the extrusion tube 217. The air outlet hole 232 is suitable for diverting the gas provided by the air pump 230 to the inside and outside of the hole after being sprayed onto the inner wall of the hole, thereby blowing the grinding debris out through the gap between the grinding disc 218 and the extrusion tube 217.

[0087] The air pump 230 can be selected according to the actual size of the processing valve body or the size of the equipment. It is preferred to use a micro air pump, which has its own battery pack to provide power and avoids interference when the air pump 230 rotates with the grinding head 24. The specific structure and working principle of the micro air pump 230 are existing technologies and will not be described in detail here.

[0088] like Figure 7-13 As shown, the valve body assembly processing equipment also includes a telescopic mechanism and an oil supply assembly;

[0089] The telescopic mechanism is connected to the movable plate 220 to be adapted to first push the movable plate 220 away from the grinding disc 218 when the extrusion tube 217 extrudes the movable plate 220, and then make the movable plate 220 open outward.

[0090] A protective surface 222 is provided on the head of the movable plate 220. The protective surface 222 is adjacent to the second grinding surface 221. When the movable plate 220 is pushed to move away from the grinding disc 218, the handle of the movable plate 220 grinds the inner wall of the hole. After the inner wall of the hole is ground smooth and the friction between the movable plate 220 and the inner wall of the hole is reduced, the movable plate 220 moves to the grinding disc 218 under the pull of the telescopic mechanism until the second grinding surface 221 contacts the inner opening. The second grinding surface 221 is suitable for grinding after contacting the inner opening, and moves to the grinding disc 218 as the burrs at the inner opening are continuously ground away, until the protective surface 222 contacts the opening. The protective surface 222 will not grind the inner opening.

[0091] The oil supply assembly is adapted to inject oil into the inner cavity of the extrusion tube 217. The extrusion tube 217 is provided with several oil outlet holes 238 that penetrate itself. The oil outlet holes 238 are adapted to discharge the oil in the extrusion tube 217 into the holes.

[0092] A switch plate 233 is slidably mounted on the outside of the extrusion tube 217. A fourth spring 234 is provided between the switch plate 233 and the fixing ring 235. The switch plate 233 has several through slots that correspond to the oil outlet holes 238 and pass through itself. When the switch plate 233 is in the initial position, it is suitable to close the oil outlet holes 238 through its non-through slot parts. A push plate 239 is provided on the moving plate 220 at a position adjacent to the protective surface 222. When the moving plate 220 moves towards the grinding disc 218, it drives the push plate 239 to move towards the switch plate 233 and pushes the switch plate 233 until the grinding is completed. The switch plate 233 is pushed until the through slots are aligned with the corresponding oil outlet holes 238 to open the oil outlet holes 238 for oiling.

[0093] like Figure 10-13 As shown, the telescopic mechanism includes a second spring 227, a third spring 228, and a roller 229;

[0094] The movable plate 220 is slidably mounted on the adjusting plate 223. The second spring 227 is located between the movable plate 220 and the adjusting plate 223. A groove is provided in the movable plate 220. The third spring 228 is located in the groove. One end of the third spring 228 is connected to the groove. The other end of the third spring 228 is connected to a housing. The roller 229 is rotatably mounted in the housing.

[0095] When the first grinding surface 219 comes into contact with the valve body, the extrusion tube 217 moves into the hole and extrudes the roller 229, causing the moving plate 220 to extend away from the grinding disc 218. Then, the roller 229 is extruded into the groove, and the first mating surface 225 extrudes the second mating surface 226 to drive the moving plate 220 to expand radially.

[0096] The oil supply assembly includes a fixed pipe 216 corresponding to the cutter head 22 and an oil storage tank. The fixed pipe 216 includes an oil inlet end and an oil outlet end. The fixed pipe 216 is fixedly installed on the corresponding cutter head 22. The oil outlet end of the fixed pipe 216 is rotatably connected to the corresponding extrusion pipe 217 through a rotary seal. The oil inlet end of the fixed pipe 216 is coaxially arranged with the corresponding cutter head 22 and passes through the cutter head 22 and the corresponding switching gear 215. The oil inlet end of the fixed pipe 216 is connected to the oil supply pipe of the oil storage tank through a rotary seal. The oil storage tank is installed on the base 21.

[0097] The oil outlet of the fixed tube 216 is connected to the extrusion tube 217 by a rotary seal to ensure that the extrusion tube 217 rotates normally under the drive of the rotating mechanism without oil leakage. The oil inlet is coaxially set with the cutter head 22 and is connected to the oil supply pipe of the oil storage tank by a rotary seal to ensure that the turntable will not twist the oil supply pipe and leak oil under the drive of the cutter changing mechanism. The oil supply pipe is not shown in the figure. The oil supply pipe needs to be fixedly set on the base 21. The specific structure and working principle of the rotary seal are existing technologies and will not be described in detail here.

[0098] The oil storage tank is suitable for storing the lubricating liquid solution used during tapping. It is equipped with a delivery pump to pump the liquid stored inside into the fixed pipe 216 through the oil delivery pipe, and finally into the extrusion pipe 217, and then discharged through the oil outlet 238. The oil storage tank is not shown in the figure. Its specific structure and working principle are existing technologies and will not be described in detail here.

[0099] The first grinding surface 219 and the second grinding surface 221 can be configured with a granulated structure, a textured structure, a coating structure, or a cutting edge, while the handle of the moving plate 220 only uses a granulated structure, a textured structure, or a coating structure, which can achieve burr grinding or cutting treatment.

[0100] In this embodiment, the linear motion mechanism drives the grinding head 24 to move toward the valve body. During the movement, the moving plate 220 extends into the hole. When the grinding disc 218 abuts against the outer hole of the flange end, the head of the moving plate 220 moves to correspond to the inner hole, but at this time there is no contact.

[0101] Once the grinding disc 218 reaches the outer opening, it can no longer move. However, driven by the linear movement mechanism, the extrusion tube 217 continues to move into the hole. During the movement of the extrusion tube 217, the grinding disc 218 slides outside the extrusion tube 217, and the extrusion tube 217 always remains in contact with the outer opening. As the extrusion tube 217 moves into the hole, its first mating surface 225 presses against the second mating surface 226 of the moving plate 220. The moving plate 220, after being pressed... The corresponding adjusting plate 223 is pushed outward and squeezes the first spring 224. After the moving plate 220 is pushed out, the handle abuts against the inner wall of the hole, and the second grinding surface 221 on the head abuts against the inner hole. When the moving plate 220 is fully pushed out, the fixing ring 235 on the extrusion tube 217 abuts against the grinding disc 218, providing support for the grinding disc 218. At this time, the rotation mechanism is started to drive the grinding head 24 to rotate as a whole, so that the inner wall of the hole and the inner and outer holes can be ground at the same time.

[0102] Furthermore, during the grinding process, the air pump 230 is activated. The air outlet of the air pump 230 introduces gas into the fixed ring 235, which then introduces the gas into the air outlet plate 231. Finally, the gas is discharged through the air outlet hole 232 on the air outlet plate 231. The air outlet plate 231 is located on the surface outside the extrusion tube 217 that does not contact the moving plate 220. When the handle of the moving plate 220 grinds the inner wall of the hole, there is a gap between the air outlet plate 231 and the inner wall of the hole. During the grinding process, the extrusion tube 217 is located inside the hole, and the gas ejected from the air outlet hole 232 acts directly on the inner wall of the hole. The airflow is split to the left and right sides upon impact with the inner wall of the hole, thereby cleaning the entire inner wall of the hole and avoiding grinding residue. The grinding disc 218 is slidably mounted on the extrusion tube 217. To avoid interference between the grinding disc 218 and the air outlet plate 231, the grinding disc 218 has a gap with the extrusion tube 217 except for the part that is slidably connected to the extrusion tube 217. When the air outlet 232 sprays air, the grinding residue in the inner wall of the hole can be discharged through the gap, and at the same time, the airflow at the inner and outer orifices is aroused, thereby cleaning the orifice.

[0103] After all the grinding is completed, the rotating mechanism stops working, and the linear movement mechanism starts, driving the grinding head 24 to move in the opposite direction to the reset. During the reverse movement, the moving plate 220 is still in the open state and cannot move until the extrusion tube 217 is completely out of the hole. Therefore, the extrusion tube 217 will move out of the hole first. After the extrusion tube 217 is completely outside the hole, the positional relationship between the grinding disc 218 and the extrusion tube 217 returns to the initial state, which is convenient for the next grinding process. At the same time, the moving plate 220 is reset by the first spring 224 after losing the support of the extrusion tube 217. The second grinding surface 221 and the handle of the moving plate 220 are disconnected from the hole. At this time, the continuous reverse movement of the extrusion tube 217 can drive the moving plate 220 to leave the hole, and finally the grinding head 24 is reset.

[0104] When severe burrs appear at the outer orifice, the second grinding surface 221 may not be able to contact the inner orifice after the first grinding surface 219 comes into contact with the outer orifice. At this time, the rotating mechanism and the linear drive mechanism can be started simultaneously after the fixed ring 235 and the grinding disc 218 come into contact. The linear drive mechanism drives the grinding disc 218 to move further towards the valve body, so that the first grinding surface 219 will first grind or remove the burrs that are causing the obstruction.

[0105] In another embodiment, when the grinding disc 218 abuts against the outer opening, the extrusion tube 217 continues to move into the hole under the drive of the linear movement mechanism. During the movement, the extrusion tube 217 first extrudes the roller 229. The roller 229 is restricted by the groove, causing the roller 229 and the moving plate 220 as a whole to be pushed to the side away from the grinding disc 218. After the moving plate 220 extends to its limit position, the continuously moving extrusion tube 217 extrudes the roller 229 into the groove. When the roller 229 is completely in the groove, the first mating surface 225 on the extrusion tube 217 then extrudes the second mating surface 226 on the moving plate 220, causing the moving plate 220 to extend outward and abut against the inner wall of the hole. At this time, due to the extension of the moving plate 220, the second grinding surface 221 of the head of the moving plate 220 does not abut against the inner opening. In this case, the rotation is started. The rotating mechanism causes the first grinding surface 219 and the handle of the moving plate 220 to grind the outer orifice and the inner wall of the orifice first. After the inner wall of the orifice is ground, the friction between the inner wall of the orifice and the handle of the moving plate 220 decreases. The previously extended moving plate 220 moves back to its original position under the action of the second spring 227. During the resetting process, the second grinding surface 221 of the moving plate 220 abuts against the inner orifice. Under the condition of abutting, it continues to rotate to grind the inner orifice. As the burrs at the inner orifice are continuously ground flat, the moving plate 220 also moves towards the grinding disc 218. The continuous rotation of the second grinding surface 221 will grind or cut a chamfer that fits with the second grinding surface 221 at the inner orifice. Finally, the end face at the inner orifice fits with the protective surface 222. When it fits with the protective surface 222, the grinding of the inner orifice is completed. The protective surface 222 will not grind the valve body.

[0106] Before the second grinding surface 221 grinds the inner opening, the grinding of the inner wall of the hole and the outer opening has been completed. Under the blowing of the air outlet 232, the grinding of the inner opening will not cause iron filings to enter the hole, avoiding the mixing of iron filings and oil during subsequent oiling, which would affect the tapping effect. As the moving plate 220 moves towards the grinding disc 218, the push plate 239 on the head of the moving plate 220 squeezes the switch plate 233, causing the switch plate 233 to slide on the extrusion tube 217. When the end face of the inner opening is in contact with the protective surface 222, the push plate 239 pushes the switch plate 233 until the through groove is aligned with the oil outlet 238. The seal on the oil outlet 238 is released, and the oil in the extrusion tube 217 is thrown out by centrifugal force under the rotation of the extrusion tube 217, spraying onto the inner wall of the hole. At this time, the gas continuously ejected from the air outlet 232 pushes the oil in the hole to flow to both sides to the inner and outer orifices when it comes into contact with the inner wall of the hole. This further improves the overall lubrication and prepares for subsequent tapping. After the grinding and lubrication work is completed, the extrusion tube 217 moves in the opposite direction and resets under the drive of the linear drive mechanism, so that the connection between the switch plate 233 and the push plate 239 is disconnected. The switch plate 233 is reset under the action of the fourth spring 234, blocking the oil outlet 238 to prevent oil leakage.

[0107] Example 3: Figure 3 As shown, this embodiment further includes the following structure based on embodiment one: the clamping mechanism 3 includes a placement plate 31, a fourth motor 32, a bidirectional screw 33, and two clamps;

[0108] The placement plate 31 is set on the frame 1, the fourth motor 32 is mounted on the placement plate 31, the bidirectional screw 33 is rotatably mounted in the placement plate 31, and the two clamps are respectively assembled on the two oppositely arranged threads of the bidirectional screw 33. The output end of the fourth motor 32 is connected to the bidirectional screw 33 to drive the bidirectional screw 33 to rotate, thereby driving the two clamps to move towards or away from each other to clamp or release the valve body.

[0109] The clamp includes a mating plate 34, two first clamping plates 35 and a second clamping plate 36. The mating plate 34 is mounted on a double-acting screw 33. The first clamping plates 35 are adapted to clamp the valve body portions at the two flange ends used for pipe connection. The second clamping plate 36 is adapted to clamp the valve body portions at the flange end of the valve cover.

[0110] like Figure 3 As shown, the placement plate 31 is rotatably mounted on the frame 1. A fifth motor 37 is installed on the frame 1. The output end of the fifth motor 37 is connected to the placement plate 31 to drive the placement plate 31 to shift its angle, thereby rotating and switching a flange end that needs to be processed to correspond to the position of the processing component 2.

[0111] The output end of the fifth motor 37 should be coaxially set with the center of the valve body. It is suitable for processing valve bodies of the same specification. When the specification of the valve body to be processed is changed, the corresponding position adjustment needs to be made.

[0112] When clamping and fixing the valve body before processing, first place the valve body between two clamps, then start the fourth motor 32 to drive the bidirectional screw 33 to rotate forward, causing the two clamps to move towards each other to clamp the valve body. After processing is completed, start the fourth motor 32 to drive the bidirectional screw 33 to rotate in reverse so that the two clamps move away from each other, and the valve body can be released to complete the disassembly.

[0113] The processing component 2 can directly perform processes such as drilling on the two flange ends used for pipe connection. When it is necessary to process the flange end at the valve cover, the fifth motor 37 can be started to drive the placement plate 31 to shift the overall angle, so that the flange end at the valve cover can be rotated to the flange end previously used for pipe connection, and then processed by the processing component 2.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
