Description

Technical Field

[0001] This application relates to the field of electromagnetic valve seat processing technology, and in particular to an electromagnetic valve seat processing device. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used for fluid control. They are actuators, and their applications are not limited to hydraulic or pneumatic systems. The primary function of solenoid valves in industrial control systems is to adjust the direction, flow rate, speed, and other parameters of the medium. During the manufacturing process, the valve seat of a solenoid valve requires machining, and to facilitate the flow of the medium, holes need to be drilled into its surface. In existing technologies, to improve the efficiency of drilling the valve seat surface, CNC cutting tools (such as carbide drill bits) are typically used, with two sets of drill bits spaced apart to achieve the machining of two holes at a time.

[0003] However, during the deep machining of solenoid valve seats, the cutting inserts (drill bits) need to operate under high loads for extended periods, leading to frequent issues such as insert wear and chipping, resulting in decreased machining accuracy and frequent tool replacements. Furthermore, because the worktable supporting the drill bit is fixed, it can only move up and down along the guide column to provide feed displacement for drilling, and cannot rotate or adjust the tool angle in the horizontal plane. Given the multi-hole design of the solenoid valve seat surface (e.g., holes at different angles and circumferential positions), operators need to constantly adjust the position of the solenoid valve seat, going through a series of tedious steps of "fixing-loosening-adjusting-locking," which not only reduces drilling accuracy but also significantly reduces the efficiency of the equipment. In addition, existing CNC inserts lack effective cooling and chip removal designs during deep machining, further limiting machining efficiency and hole surface quality. Therefore, it is necessary to further optimize the existing solenoid valve seat machining equipment to improve its efficiency and tool life. Summary of the Invention

[0004] This application proposes a solenoid valve seat processing device, which has the advantage of high working efficiency and is used to solve the problem of low working efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: a solenoid valve seat processing device, comprising: A workbench, the top of which is equipped with a column and a top plate, the top of which is equipped with a telescopic rod, and the telescopic end of which is equipped with a support platform; The motion table is rotatably mounted on the bottom of the support platform. A support column is fixedly installed on the top of the inner wall of the motion table. Two sets of sliders are slidably mounted on the outer surface of the support column. A connecting block is fixedly connected to the bottom of the sliders. Two sets of support grooves are opened at the bottom of the motion table. A slider is slidably mounted inside the support groove. A rotating shaft is rotatably mounted inside the connecting block and the slider. A drill rod is installed at the bottom of the rotating shaft. Motor 2 is installed at the bottom of the inner wall of the motion table. The output shaft of Motor 2 is fixedly connected to a connecting plate. Both ends of the connecting plate are hinged with adapter plates. One end of the adapter plate is movably sleeved on the outer surface of the connecting block. This device achieves more efficient drilling of solenoid valve seats by setting up two sets of drill rods with adjustable spacing and a rotatable moving table. Through optimization, under the same processing environment, the solenoid valve seat only needs to be fixed and locked once to complete the drilling of all holes on its surface, doubling work efficiency. To achieve this, the device is designed with the following structure: By setting up a support platform with columns for sliding support and telescopic rods for feeding support, and by setting up a motor and a rotating block inside the support platform, the motor can drive the rotating block and the moving table to rotate freely 365°, and drive the two sets of drill rods located at the bottom of the moving table to rotate freely, synchronously adapting to the holes to be processed at different positions on the surface of the solenoid valve seat. This design utilizes the principle of relative motion, so that the workpiece can be processed at other positions without secondary disassembly and reinstallation.

[0006] This device has two sets of support columns installed inside the motion table, which provide sliding support for slider two. A connecting block is fixedly installed at the bottom of slider two, and slider one, which is movably mounted inside the support groove, is slidably engaged with slider one. The rotating shaft can drive the drill rod to rotate relative to slider one and the connecting block. In order to realize the synchronous reverse spacing adjustment function of the two sets of rotating shafts and drill rods, a motor two is set in the middle of the motion table cavity, which drives the connecting plate to rotate. Two sets of adapter plates hinged at both ends of the connecting plate are movably sleeved with the connecting block, so that the two sets of connecting blocks, rotating shafts and drill rods can realize automatic spacing adjustment to adapt to the valve seat surface holes with different spacing.

[0007] Finally, this device features a completely new power system that eliminates the influence of power transmission on the two sets of drill rods used for adjusting the distance between them. A bracket located inside the motion table supports the drive shaft, motor three, and worm gear. Two sets of worm gears are slidably mounted on the surface of the drive shaft, and the worm gears can slide freely along the axis of the drive shaft via splines on the drive shaft surface. This design ensures that the rotating shaft, drill rods, and gears can adjust the distance horizontally by driving the worm gears. Furthermore, the motor three drives the drive shaft, transmitting power through the worm gears to the gears and rotating shaft, resulting in higher overall practicality and reliability.

[0008] Preferably, a rotating block is rotatably mounted on the bottom of the support platform, a motor is mounted on the top of the support platform, the output shaft of the motor is fixedly connected to the rotating block, and the bottom of the rotating block is fixedly connected to the motion platform. like Figure 4 As shown, the motor drives the rotating block mounted on the bottom of the support platform to rotate, thereby enabling the synchronous rotation of the moving table and the drill rod, which can be adapted to the holes to be processed located at different positions on the surface of the solenoid valve seat.

[0009] Preferably, a bracket is fixedly installed at the bottom of the inner wall of the motion table, a drive shaft is rotatably installed inside the bracket, a motor is installed on the outer side of the bracket, the output shaft of the motor is fixedly connected to the drive shaft, two sets of worm gears are slidably installed on the outer surface of the drive shaft through splines, and a gear is fixedly installed on the outer surface of the shaft, with the worm gears meshing with the gears; like Figure 1 As shown, the gears connected to the two sets of rotating shafts mesh with the corresponding worm gears. Motor 3 drives the gears, rotating shafts, and drill rods to rotate by driving the transmission shaft and worm gear. Motor 2 drives the connecting plate and adapter plate to rotate. When the distance between the two sets of rotating shafts is changed, the rotating shaft will drive the gears and worm gears to slide along the axis of the transmission shaft. At this time, the worm gear can be moved to adapt without interference and without affecting the power output of motor 3 to the drill rod.

[0010] Preferably, the columns are configured in two sets and are symmetrically distributed on both sides of the top of the workbench. The top plate is fixedly installed on the top of the columns, and the support platform is slidably installed on the outer surface of the columns. like Figure 4 The support platform shown can be guided by the column to stabilize its movement, while the telescopic rod is located at the top of the top plate, providing power for the feed movement of the support platform and the moving platform.

[0011] Preferably, a slot is provided on the top of the outer surface of the connecting block, and the adapter plate is movably sleeved in the slot. The two sets of adapter plates are centrally symmetrically distributed with the center of the connecting plate as the reference. like Figure 8 As shown, one end of the adapter plate is movably sleeved in the slot and movably sleeved with the connecting block. While the two sets of adapter plates drive the connecting block to move, they are guided by the support column and the second slider, thereby achieving synchronous rotation angle and synchronous movement of the two sets of rotating shafts.

[0012] Preferably, the side cross-section of the slider is I-shaped, and the slider is slidably engaged with the inner wall of the support groove; like Figure 7As shown, the "I"-shaped slider one can slide freely on the inner wall of the support groove and cooperate with slider two and connecting block to stabilize the motion axis of the rotating shaft and drill rod.

[0013] Preferably, the bracket, motor three, and drive shaft are all located behind the rotating shaft and motor two, and the connecting plate is located below the support column; like Figure 1 As shown, the motor drives the transmission shaft to rotate, and through the worm gear and gears, it drives the rotating shaft and drill rod to rotate. There is space between the support column and the connecting plate to effectively prevent interference.

[0014] Preferably, the number of the support columns is set to two sets, which are distributed symmetrically in parallel front and back, and the two sets of sliders can slide synchronously in opposite directions along the surface of the support columns; like Figure 1 As shown, the two sets of support columns provide guiding support for the second slider, enabling it to slide horizontally stably. The connecting plate and adapter plate are located below the support columns, thereby driving the movement between the two sets of rotating shafts and the drill rod to achieve the spacing adjustment function.

[0015] The beneficial effects of this invention are as follows: This device achieves more efficient drilling of solenoid valve seats by setting up two sets of drill rods with adjustable spacing and a rotatable moving table. Through optimization, under the same processing environment, the solenoid valve seat only needs to be fixed and locked once to complete the drilling of all holes on its surface, doubling work efficiency. To achieve this, the device is designed with the following structure: 1. By setting up a column as a support platform with sliding support and a telescopic rod to provide feed support for the support platform, and by setting a motor and a rotating block inside the support platform, the motor can drive the rotating block and the moving table to rotate freely 365°, and drive the two sets of drill rods located at the bottom of the moving table to rotate freely, synchronously adapting to the holes to be processed at different positions on the surface of the solenoid valve seat. This design utilizes the principle of relative motion, so that the workpiece can be processed at other positions without secondary disassembly and reinstallation.

[0016] 2. This device has two sets of support columns installed in the inner cavity of the motion table, and the second slider is slidably supported by the support columns. The connecting block fixedly installed at the bottom of the second slider and the first slider movably installed in the support groove have a rotating shaft. The rotating shaft can drive the drill rod to rotate relative to the first slider and the connecting block. In order to realize the synchronous reverse spacing adjustment function of the two sets of rotating shafts and drill rods, a second motor located in the middle of the inner cavity of the motion table is installed to drive the connecting plate to rotate. The two sets of adapter plates hinged at both ends of the connecting plate are movably connected to the connecting block, so that the two sets of connecting blocks, rotating shafts and drill rods can realize automatic spacing adjustment to adapt to the valve seat surface holes with different spacing.

[0017] 3. Finally, this device features a completely new power system that eliminates the influence of power transmission on the two sets of drill rods used for adjusting the distance. A bracket located inside the motion table supports the drive shaft, motor three, and worm gear. Two sets of worm gears are slidably mounted on the surface of the drive shaft, and the worm gears can slide freely along the axis of the drive shaft via splines on the drive shaft surface. This design ensures that the rotating shaft, drill rods, and gears can adjust the distance horizontally by driving the worm gears. Furthermore, the motor three drives the drive shaft, transmitting power through the worm gears to the gears and rotating shaft, resulting in higher overall practicality and reliability.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1-8 This embodiment discloses a solenoid valve seat processing device, including: Workbench 1, with a column 2 and a top plate 3 installed on the top of the workbench 1, a telescopic rod 4 installed on the top of the top plate 3, and a support platform 5 installed at the telescopic end of the telescopic rod 4. The motion table 6 is rotatably mounted on the bottom of the support platform 5. A support column 12 is fixedly installed on the top of the inner wall of the motion table 6. Two sets of sliders 13 are slidably mounted on the outer surface of the support column 12. A connecting block 14 is fixedly connected to the bottom of the sliders 13. Two sets of support grooves 11 are opened at the bottom of the motion table 6. A slider 8 is slidably mounted inside the support groove 11. A rotating shaft 9 is rotatably mounted inside the connecting block 14 and the slider 8. A drill rod 10 is installed at the bottom of the rotating shaft 9. Motor 2 15 is installed at the bottom of the inner wall of the motion table 6. The output shaft of motor 2 15 is fixedly connected to a connecting plate 16. Both ends of the connecting plate 16 are hinged with adapter plates 17. One end of the adapter plate 17 is movably sleeved on the outer surface of the connecting block 14. This device achieves more efficient drilling of solenoid valve seats by setting up two sets of drill rods 10 with adjustable spacing and a rotatable motion table 6. After optimization, under the same processing environment, the solenoid valve seat only needs to be fixed and locked once to complete the drilling of all holes on its surface, thus doubling the work efficiency. To achieve this goal, the device is designed with the following structure: The support platform 5 is supported by a column 2 and a sliding support. The support platform 5 is fed by a telescopic rod 4. The support platform 5 is equipped with a motor 7 and a rotating block 23. The motor 7 can drive the rotating block 23 and the moving table 6 to rotate freely 365°, and drive the two sets of drill rods 10 located at the bottom of the moving table 6 to rotate freely, synchronously adapting to the holes to be processed at different positions on the surface of the solenoid valve seat. This design utilizes the principle of relative motion, so that the workpiece can be processed at other positions without secondary disassembly and reinstallation.

[0023] This device has two sets of support columns 12 installed in the inner cavity of the motion table 6, and the second slider 13 is slidably supported by the support columns 12. The connecting block 14 fixedly installed at the bottom of the second slider 13 and the first slider 8 slidably engaged in the support groove 11 are movably mounted with a rotating shaft 9. The rotating shaft 9 can drive the drill rod 10 to rotate relative to the first slider 8 and the connecting block 14. In order to realize the synchronous reverse spacing adjustment function of the two sets of rotating shafts 9 and drill rod 10, a second motor 15 located in the middle of the inner cavity of the motion table 6 is installed to drive the connecting plate 16 to rotate. The two sets of adapter plates 17 hinged at both ends of the connecting plate 16 are movably sleeved with the connecting block 14, so that the two sets of connecting blocks 14, rotating shafts 9 and drill rod 10 can realize automatic spacing adjustment to adapt to the valve seat surface holes with different spacing.

[0024] Finally, this device, through the installation of a completely new power system, ensures that the two sets of drill rods 10 for adjusting the distance of motion are not affected by power transmission. A bracket 18 located inside the motion table 6 supports the drive shaft 20, motor 19, and worm gear 21. Two sets of worm gears 21 are slidably mounted on the surface of the drive shaft 20, and the worm gears 21 can slide freely along the axis of the drive shaft 20 via splines on its surface. This design ensures that the rotating shaft 9, drill rods 10, and gear 22 can adapt to the horizontal movement of the worm gears 21 during the distance adjustment. Furthermore, the motor 19 drives the drive shaft 20 to transmit power via the worm gears 21 to the gear 22 and rotating shaft 9, resulting in higher overall practicality and reliability.

[0025] In this embodiment, a rotating block 23 is rotatably mounted on the bottom of the support platform 5, a motor 7 is mounted on the top of the support platform 5, the output shaft of the motor 7 is fixedly connected to the rotating block 23, and the bottom of the rotating block 23 is fixedly connected to the motion platform 6. like Figure 4 As shown, motor 7 drives the rotating block 23, which is rotatably mounted on the bottom of the support platform 5, to rotate, thereby enabling the synchronous rotation of the motion table 6 and the drill rod 10, and adapting to the holes to be processed located at different positions on the surface of the solenoid valve seat.

[0026] In this embodiment, a bracket 18 is fixedly installed at the bottom of the inner wall of the motion table 6. A transmission shaft 20 is rotatably installed inside the bracket 18. A motor 3 19 is installed on the outer side of the bracket 18. The output shaft of the motor 3 19 is fixedly connected to the transmission shaft 20. Two sets of worm gears 21 are slidably installed on the outer surface of the transmission shaft 20 through splines. A gear 22 is fixedly installed on the outer surface of the rotating shaft 9. The worm gears 21 and the gears 22 mesh with each other. like Figure 1As shown, the gears 22 connected to the two sets of rotating shafts 9 are respectively meshed with the corresponding worm gears 21. The motor 3 19 drives the transmission shaft 20 and the worm gear 21 to drive the rotation of the gears 22, rotating shafts 9 and drill rod 10. The motor 2 15 drives the connecting plate 16 and the adapter plate 17 to rotate. When the distance between the two sets of rotating shafts 9 is changed, the rotating shaft 9 will drive the gears 22 and worm gear 21 to slide along the axis of the transmission shaft 20. At this time, the worm gear 21 can be adapted by movement without interference and without affecting the power output of the motor 3 19 to the drill rod 10.

[0027] In this embodiment, the columns 2 are set in two groups and are symmetrically distributed on both sides of the top of the workbench 1. The top plate 3 is fixedly installed on the top of the columns 2, and the support platform 5 is slidably installed on the outer surface of the columns 2. like Figure 4 The support platform 5 shown can be guided by the column 2 to stabilize its movement, while the telescopic rod 4 is located at the top of the top plate 3, providing power for the feed movement of the support platform 5 and the motion platform 6.

[0028] In this embodiment, a slot 24 is provided on the top of the outer surface of the connecting block 14, and the adapter plate 17 is movably sleeved in the slot 24. The two sets of adapter plates 17 are centrally symmetrically distributed with the center of the connecting plate 16 as the reference. like Figure 8 As shown, one outer end of the adapter plate 17 is movably sleeved in the slot 24 and movably sleeved with the connecting block 14. While the two sets of adapter plates 17 drive the connecting block 14 to move, they are guided by the support column 12 and the slider 13, thereby achieving synchronous rotation angle and synchronous movement of the two sets of rotating shafts 9.

[0029] In this embodiment, the side cross-section of slider 8 is "I" shaped, and slider 8 is slidably engaged with the inner wall of support groove 11. like Figure 7 As shown, the "I"-shaped slider 8 can slide freely on the inner wall of the support groove 11 and cooperates with the slider 13 and the connecting block 14 to stabilize the motion axis of the rotating shaft 9 and the drill rod 10.

[0030] In this embodiment, the bracket 18, the third motor 19, and the transmission shaft 20 are all located behind the rotating shaft 9 and the second motor 15, and the connecting plate 16 is located below the support column 12. like Figure 1 As shown, motor 19 drives transmission shaft 20 to rotate, and drives rotating shaft 9 and drill rod 10 to rotate through worm gear 21 and gear 22. There is space between support column 12 and connecting plate 16 to effectively prevent interference.

[0031] In this embodiment, the number of support columns 12 is set to two sets, which are distributed in parallel and symmetrical arrangement. The two sets of sliders 13 can slide synchronously in opposite directions along the surface of the support column 12. like Figure 1 As shown, the two sets of support columns 12 provide guiding support for the slider 13, enabling it to slide horizontally stably. The connecting plate 16 and the adapter plate 17 are located below the support columns 12, thereby driving the movement between the two sets of rotating shafts 9 and the drill rod 10 to achieve the spacing adjustment function.

[0032] Working principle: When this device is in operation: First, the workpiece is fixed to the top of the worktable 1 and locked. Then, the distance between the two sets of drill rods 10 is adjusted according to the hole spacing on the valve seat surface. Figure 1 and Figure 4 As shown, start motor 15 and drive connecting plate 16 to rotate, which in turn drives adapter plate 17 and two sets of connecting blocks 14 to move synchronously in the opposite direction along the surface of support column 12, thereby changing the distance between the two sets of connecting blocks 14, rotating shaft 9 and drill rod 10. Then, when the rotating shaft 9 and the drill rod 10 drive the slider 8 and the worm 21 to move horizontally, the transmission shaft 20 remains stationary. The worm 21 can move along the spline on the surface of the transmission shaft 20 under the drive of the gear 22 to adapt until the distance between the two sets of drill rods 10 is adjusted. Then, the motor 15 is stopped. Then, the motor 7 is started and drives the rotating block 23 and the motion table 6 to rotate as a whole, so that the two sets of drill rods 10 can adapt to the hole processing position on the surface of the solenoid valve seat without moving the workpiece again. Finally, stop motor 7 and start motor 3 19. Power is synchronously transmitted to the two sets of drill rods 10 through transmission shaft 20, worm gear 21 and gear 22. Start telescopic rod 4 and drive support table 5, moving table 6 and drill rod 10 to move downward. Drill rod 10 drills the solenoid valve seat by rotating. After the machining is completed, telescopic rod 4 drives drill rod 10 to reset downward. Motor 7 drives moving table 6 and drill rod 10 to rotate to fit other holes. Motor 3 19 drives transmission shaft 20, worm gear 21, gear 22 and rotating shaft 9 to provide power to drill rod 10. No secondary disassembly and reinstallation is required before the solenoid valve seat is machined.
