This device facilitates simultaneous drilling on different surfaces of the valve body, and the drilling position is easy to adjust, making it convenient to use. However, drilling the valve body requires steps such as installation, fixing, opening, and disassembly. Other operations cannot be performed while drilling the valve body, and the current valve body must be drilled. Due to the long opening time of the valve body, the opening efficiency of the valve body is low. Summary of the Invention

The main purpose is to solve the problem that other operations cannot be performed while drilling the valve body, and the drilling efficiency of the valve body is low due to the long drilling time.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

An installation module for placing the valve body body is provided on the mover of the magnetic levitation conveyor belt. Both ends of the top of the frame are provided with drilling modules for drilling the valve body body. Support modules for auxiliary support of the installation modules are provided on both sides of the frame below the drilling modules.

[0009] Furthermore, the installation module includes a mounting base, with multiple inserts on the lower end face of the mounting base. The magnetic levitation conveyor has multiple mounting holes on its top that mate with the inserts. Multiple annularly distributed positioning plates are fixedly connected to the upper end face of the mounting base. The gap between two adjacent positioning plates is a positioning groove and a fixing groove. The positioning groove and the fixing groove are spaced apart, and the protruding part of the valve body is located in the positioning groove. The fixing groove is provided with a limiting component for fixing the valve body.

[0010] Based on the aforementioned scheme, the limiting component includes an elastic pressure plate, with rotating columns at the upper ends of both sides of the elastic pressure plate and limiting columns at the lower ends of both sides of the elastic pressure plate. The side walls of the positioning plates on both sides of the elastic pressure plate are provided with slots that cooperate with the rotating columns and limiting grooves that cooperate with the limiting columns.

[0011] As a further embodiment of the present invention, the drilling module includes a three-axis linear module fixed to the top of the frame. The Z-axis movable end of the three-axis linear module is fixed to a mounting bracket by bolts. A servo motor is fixed to the bottom of the mounting bracket by bolts. The output shaft of the servo motor passes through the mounting bracket and is keyed to a drill chuck. A drill bit is held in the drill chuck. A cooling component for dissipating heat from the drill bit is installed on the mounting bracket.

[0012] Furthermore, the cooling component includes a water outlet pipe fixed to the bottom of the mounting bracket, with the water outlet of the water outlet pipe facing the drill bit. The top of the water outlet pipe passes through the mounting bracket and is fixed with an external hose connected to an external water pump by a clamp.

[0013] Based on the aforementioned scheme, the support module includes two fixed frames fixed on both sides of the frame. The top of the inner wall of each of the two fixed frames is fixed with two guide rods by bolts. The guide rods are bent rods. The outer circumferential walls of the two guide rods are slidably connected with support frames. The top of the frame is fixed with multiple top frames for supporting the other end of the support frames by bolts. The bottom inner wall of the fixed frame is provided with a power component to push the support frames to move.

[0014] As a further embodiment of the present invention, the power assembly includes a cylinder fixed to the bottom of the fixed frame, a connecting frame fixed to the top of the cylinder piston rod by bolts, and a lever arm rotatably connected to the top of the connecting frame and rotatably connected to the support frame.

[0015] Furthermore, an inclined drain groove is provided on the upper surface of the mounting base, and a guide groove is provided on the upper surface of the support frame, with the drain groove and the guide groove being perpendicular when viewed from above.

[0016] Based on the aforementioned scheme, protective plates are welded around the periphery of multiple mounting bases, and the protective plates cover three sides of the mounting bases, with the height of the protective plates not exceeding the bottom of the three-axis linear module.

[0017] Beneficial effects

[0018] Compared with the prior art, the present invention provides a multi-axis drilling device for valve body casting flanges, which has the following advantages:

[0019] 1. This invention enables secondary drilling operations through the combined use of a drilling module, an installation module, and a support module, allowing pre-drilling and precision drilling to be performed simultaneously, thereby reducing the overall drilling time of the valve body. Furthermore, during drilling, workers can perform operations such as placing, replacing, and flipping the valve body, ensuring that drilling, loading, unloading, and repositioning do not interfere with each other, further improving the drilling efficiency of the valve body flange.

[0020] 2. The present invention provides an installation module that places the flange at the bottom of the valve body between multiple positioning plates and positioning grooves. The positioning grooves restrict the position of the valve body, preventing it from rotating and allowing it to be placed stably on the mounting base, thereby improving the drilling accuracy of the flange.

[0021] 3. The present invention has a limiting component. The rotating column is inserted into the slot and the limiting column enters the limiting groove, so that the steel plate of the elastic pressure plate tightly presses the valve body body, thereby preventing the valve body body from rotating and improving the fixing effect of the valve body body.

[0022] 4. The present invention has a drilling module, which can adjust the position of the drill bit as needed, thereby realizing the drilling of different positions on the top flange of the valve body without adjusting the position of the valve body during the drilling process, thus improving the drilling convenience of the device.

[0023] 5. This invention incorporates a cooling component. A water pump delivers cooling oil to the outlet pipe via an external hose, and the oil flows through the outlet to the openings of the drill bit and valve body, thereby cooling the valve body and drill bit and improving the service life of the drill bit.

[0024] 6. By incorporating a support module, this invention transforms the force on the mounting base during drilling into a support frame, thereby preventing the mounting base from changing position during drilling, improving the stability of the valve body during drilling, and simultaneously enhancing the protection of the magnetic levitation conveyor belt.

[0036] Reference Figures 1-7 A multi-axis drilling device for valve body casting flanges includes a frame 1 and a valve body 7. A magnetic levitation conveyor belt 2, model MiTS-LH, is bolted to the top of the frame 1. The conveyor belt mainly includes a main station module, a power supply module, a guide rail module, and multiple movers. The main station module, power supply module, guide rail module, and multiple movers are all electrical equipment. The number of movers can be configured according to requirements, which will not be elaborated further here. The movers of the magnetic levitation conveyor belt 2 are equipped with mounting modules 5 for placing the valve body 7. Both ends of the top of the frame 1 are equipped with mounting modules for the valve body. 7. The drilling module 4 performs drilling. Support modules 6 are located on both sides of the frame 1 below the drilling module 4 to provide auxiliary support for the installation module 5. In use, the valve body 7 is placed on the installation module 5, and then the installation module 5 is placed on the mover of the magnetic levitation conveyor belt 2. The main station module on the magnetic levitation conveyor belt 2 controls the mover, causing the mover to move the installation module 5 and the valve body 7 below the drilling module 4. The support modules 6 provide auxiliary support for the installation module 5, and the front-end drilling module 4 provides support for the valve body 7. Pre-drill holes in the flange above body 7. After pre-drilling, remove the support module 6 from the mounting module 5. Use the mover again to move the mounting module 5 and valve body 7 to the drilling module 4 at the rear. Use the support module 6 at this location to support the mounting module 5. Then use the drilling module 4 to perform secondary drilling on the flange above the valve body 7 on the support module 6, thus completing the drilling operation on the flange above the valve body 7. After drilling, remove the support module 6 from the mounting module 5. Use the mover again to move the mounting module 5 and valve body 7 to the rear. At the operator's location, the operator can adjust or replace the flange position of the valve body 7 according to its type. Through secondary drilling, pre-drilling and precision drilling of the flange can be achieved, improving the drilling accuracy of the flange. At the same time, pre-drilling and precision drilling can be carried out simultaneously, so that the drilling time of the two valve bodies 7 overlaps, thereby reducing the overall drilling time of the valve body 7. Furthermore, during drilling, the operator can perform operations such as placement, replacement, and flipping of the valve body 7, so that drilling, loading, unloading, and repositioning do not interfere with each other, further improving the drilling efficiency of the valve body 7 flange.

[0037] To place the valve body 7 onto the mover, the mounting module 5 in this invention includes a mounting base 501. Multiple inserts 504 are provided on the lower end face of the mounting base 501. Multiple mounting holes 3 that mate with the inserts 504 are opened on the top of the mover of the magnetic levitation conveyor belt 2. Multiple annularly distributed positioning plates 505 are fixedly connected to the upper end face of the mounting base 501. The distance between the positioning plates 505 can be changed according to the flange shape of the valve body 7, thereby forming different placement molds. The gap between two adjacent positioning plates 505 is a positioning groove 507 and a fixing groove 50. 8. The positioning groove 507 and the fixing groove 508 are spaced apart, and the protruding part of the valve body 7 is located in the positioning groove 507. The fixing groove 508 is provided with a limiting component to fix the valve body 7. The flange at the bottom of the valve body 7 is placed between multiple positioning plates 505 and the positioning groove 507. The positioning groove 507 restricts the position of the valve body 7 so that the valve body 7 will not rotate. Then the limiting component is used to fix the valve body 7, so that the valve body 7 can be placed stably on the mounting base 501, thereby making the drilling accuracy of the flange higher.

[0038] To fix the valve body 7, the limiting component in this invention includes an elastic pressure plate 506, which is welded from two different metal plates. The side plate is elastic and the top plate is rigid. The side plate is preferably made of titanium alloy or magnesium alloy and the top plate is made of steel plate. Rotating columns 509 are welded to the upper ends of both sides of the elastic pressure plate 506, and limiting columns 510 are welded to the lower ends of both sides of the elastic pressure plate 506. The side walls of the positioning plates 505 on both sides of the elastic pressure plate 506 are provided with slots 511 that cooperate with the rotating columns 509 and limiting grooves 512 that cooperate with the limiting columns 510. During fixing, first insert the rotating column 509 into the slot 511. At this time, the steel plate of the elastic pressure plate 506 will press tightly against the valve body 7, preventing the valve body 7 from rotating. Then, pry the side plate of the elastic pressure plate 506 so that the limiting column 510 enters the limiting groove 512, thereby fixing the elastic pressure plate 506 and thus fixing the valve body 7, improving the fixing effect of the valve body 7.

[0039] To drill a hole in the flange at the top of the valve body 7, the drilling module 4 in this invention includes a three-axis linear module 401 fixed to the top of the frame 1. The model of the three-axis linear module 401 is FSK40XYZ-L. The Z-axis movable end of the three-axis linear module 401 is fixed to a mounting bracket 402 by bolts. A servo motor 403 is fixed to the bottom inner wall of the mounting bracket 402 by bolts. The output shaft of the servo motor 403 passes through the mounting bracket 402 and is keyed to a drill chuck 406. The other end of the drill chuck 406 holds a drill bit 407. The bottom inner wall of the mounting bracket 402 is provided with a drill bit holder. The cooling component 407 dissipates heat. When the valve body 7 is below the drill bit 407, the servo motor 403 and the three-axis linear module 401 are activated. The three-axis linear module 401 drives the servo motor 403 and the drill bit 407 to move. The servo motor 403 drives the drill bit 407 to rotate, thereby realizing the drilling operation on the flange at the top of the valve body 7. The position of the drill bit 407 can be adjusted according to the needs, thereby realizing the opening of holes at different positions of the flange at the top of the valve body 7. There is no need to adjust the position of the valve body 7 during the drilling process, which improves the drilling convenience of the device.

[0040] To dissipate heat from the drill bit 407, the cooling component in this invention includes a water outlet pipe 405 fixed to the bottom of the mounting bracket 402, with the outlet of the water outlet pipe 405 facing the drill bit 407. The top of the water outlet pipe 405 passes through the mounting bracket 402 and is fixed with an external hose 404 connected to an external water pump by a clamp. When the external water pump is started, the water pump delivers cooling oil through the external hose 404 to the water outlet pipe 405, and then flows through the outlet to the opening between the drill bit 407 and the valve body 7, thereby cooling the valve body 7 and the drill bit 407 and improving the service life of the drill bit 407.

[0041] To support the mounting base 501 during drilling, the support module 6 in this invention includes two fixed frames 601 fixed to both sides of the frame 1. Two guide rods 605 are bolted to the top of the inner walls of both fixed frames 601. The guide rods 605 are bent rods. Supports 606 are slidably connected to the outer circumference of the two guide rods 605. Multiple top frames 608 for supporting the other end of the support frames 606 are bolted to the top of the frame 1. A power assembly for pushing the support frames 606 is provided on the bottom inner wall of the fixed frames 601. When the valve body 7 moves to the drilling position... When the head 407 is below, the power component drives the support 606 to move on the guide rod 605. One end of the support 606 will first contact the mounting base 501. When the support 606 moves to the innermost side, one end of the support 606 will contact the top frame 608. Thus, the top frame 608 supports the other end of the support 606, so that the force on the mounting base 501 when drilling is changed to the support 606. This prevents the mounting base 501 from changing position when drilling, improves the stability of the valve body 7 when drilling, and also improves the protection effect on the magnetic levitation conveyor belt 2.

[0042] To move the support frame 606, the power assembly in this invention includes a cylinder 602 fixed to the bottom of the fixed frame 601. The top of the piston rod of the cylinder 602 is fixed to a connecting frame 603 by bolts. The top of the connecting frame 603 is rotatably connected to a lever arm 604 rotatably connected to the support frame 606. When the cylinder 602 is activated, it drives the connecting frame 603 to move upward or downward, thereby causing the connecting frame 603 to press one end of the lever arm 604, which in turn causes the lever arm 604 to push or pull the support frame 606 to move, thus automating the device.

[0043] It should be further explained that protective plates 502 are welded to the top of multiple mounting bases 501, and the protective plates 502 cover three sides of the mounting base 501. The height of the protective plates 502 does not exceed the bottom of the three-axis linear module 401, thus ensuring that the protective plates 502 do not interfere with flange drilling. When drilling the flange above the valve body 7, the generated debris and splashed cooling oil are blocked by the protective plates 502, causing the debris and cooling oil to fall onto the mounting base 501. An inclined drain groove 503 is provided on the upper surface of the mounting base 501, and a guide groove 607 is provided on the upper surface of the support 606. The drain groove 503... 03 is perpendicular to the liquid guide groove 607 when viewed from above. After the flange above the valve body 7 is opened, the support 606 is reset by the power component. Since the guide rod 605 is a bent rod, the support 606 will cause one end of the mounting seat 501 to tilt slightly, so that the cooling oil falling on the mounting seat 501 flows from the drain groove 503 to the support 606, and then flows to the liquid guide groove 607. The cooling oil flows from the liquid guide groove 607 to both sides of the support 606 and is collected by the oil receiving tank at the bottom, so that the cooling oil and waste will not damage the electrical components and further improve the service life of the device.

[0044] The present invention is used in the following steps:

[0045] S1: Place the flange at the bottom of the valve body 7 between multiple positioning plates 505 and positioning grooves 507. The positioning grooves 507 restrict the position of the valve body 7 so that the valve body 7 will not rotate.

[0046] S2: Insert the rotating column 509 into the slot 511. At this time, the steel plate of the elastic pressure plate 506 will press the valve body 7 tightly, so that the valve body 7 will not rotate. Then, pry the side plate of the elastic pressure plate 506 so that the limiting column 510 enters the limiting groove 512, thereby fixing the elastic pressure plate 506 and thus fixing the valve body 7. Place the mounting base 501 with the valve body 7 on the mover on the magnetic levitation conveyor belt 2.

[0047] S3: The main station module on the magnetic levitation conveyor belt 2 controls the mover on the magnetic levitation conveyor belt 2, so that the valve body 7 moves to below the drill bit 407 at the front end;

[0048] S4: Start cylinder 602. Cylinder 602 drives connecting frame 603 to move upward, thereby causing connecting frame 603 to press one end of lever arm 604, which in turn causes lever arm 604 to push support frame 606 to move. Thus, one end of support frame 606 will first contact mounting base 501. When support frame 606 moves to the innermost side, one end of support frame 606 will contact top frame 608. Thus, top frame 608 supports the other end of support frame 606, so that the force on mounting base 501 when drilling is changed to support frame 606, thereby preventing the position of mounting base 501 from changing when drilling.

[0049] S5: Start the servo motor 403 and the three-axis linear module 401. The three-axis linear module 401 drives the servo motor 403 and the drill bit 407 to move. The servo motor 403 drives the drill bit 407 to rotate, thereby realizing the pre-drilling operation on the flange at the top of the valve body 7. The position of the drill bit 407 can be adjusted according to the requirements, thereby realizing the opening of holes at different positions of the flange at the top of the valve body 7.

[0050] S6: When drilling with drill bit 407, start the external water pump. The water pump delivers cooling oil through external hose 404 to water outlet 405, and then flows through the water outlet to the opening between drill bit 407 and valve body 7, thereby cooling valve body 7 and drill bit 407.

[0051] S7: After the hole is drilled, the cylinder 602 is started again. The cylinder 602 drives the connecting frame 603 to move downward, thereby causing the connecting frame 603 to pull one end of the lever arm 604, which in turn causes the lever arm 604 to pull the support frame 606 to reset.

[0052] S8: During the resetting process of the support 606, since the guide rod 605 is a bent rod, the support 606 will cause one end of the mounting base 501 to tilt slightly, so that the cooling oil falling on the mounting base 501 flows from the drain trough 503 to the support 606, and then the cooling oil flows to the guide trough 607, so that the cooling oil flows from the guide trough 607 to both sides of the support 606 and is collected by the oil receiving bucket at the bottom, so that the cooling oil and waste will not damage the electrical components.

[0053] S9: Again, the main station module on the magnetic levitation conveyor belt 2 controls the mover on the magnetic levitation conveyor belt 2 to move the valve body 7 to below the drill bit 407 at the rear end. Repeat the opening operation process at the front end to complete the finishing of the flange on the upper part of the valve body 7. After the opening is completed, the main station module on the magnetic levitation conveyor belt 2 controls the mover on the magnetic levitation conveyor belt 2 to move the valve body 7 to the rear workers. The workers can change the flange position or replace the valve body 7 according to the type of valve body 7. Repeat the process on the other side in turn.

[0054] S10: By performing secondary drilling, pre-drilling and precision drilling of the flange are achieved, improving the drilling accuracy of the flange. At the same time, pre-drilling and precision drilling can be carried out simultaneously, allowing the drilling time of the two valve body bodies 7 to overlap, thereby reducing the overall drilling time of the valve body bodies 7. Furthermore, during drilling, workers can perform operations such as placement, replacement, and flipping of the valve body bodies 7, ensuring that drilling, loading, unloading, and positioning do not interfere with each other, further improving the drilling efficiency of the valve body body 7 flange.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
