Description

[0001] This invention relates to the field of milling, specifically to a milling device for an AC generator decoupling shock-absorbing pulley. Background Technology

[0002] The decoupling damper pulley milling equipment is a specialized CNC milling machine designed for the precision machining needs of key components such as aluminum alloy / cast iron wheel hubs, damping end caps, and limiting tooth grooves. It integrates a high-precision spindle system, flexible adaptive fixtures, and multi-process linkage feed mechanism, enabling integrated milling of the damper pulley decoupling device from datum surface machining and limiting groove forming to mounting hole chamfering. The machining accuracy and efficiency are adapted to the requirements of large-scale production.

[0003] The machine is programmed parametrically through a PLC control system, which can preset process parameters such as milling depth, feed rate, and tool speed to adapt to the processing requirements of different models of decoupler vibration damping pulleys. However, when milling workpieces, some workpieces need to be milled on both sides. In this case, the workpiece needs to be flipped. In this process, the workpiece needs to be disassembled first, then flipped, and then fixed. This process is not only cumbersome, but also prone to workpiece displacement during the flipping and fixing process, which will affect the accuracy of milling. Summary of the Invention

[0004] The purpose of this invention is to provide a milling device for an AC generator decoupling damping pulley, in order to solve the problem of inconvenience in performing two-sided milling on a workpiece.

[0006] The flipping component includes rotating blocks mounted on both sides of the mounting frame. The rotating blocks are rotatably connected to the mounting frame via bearings. One end of the clamp is fixed with a rod that passes through the rotating blocks. A worm gear is fixedly connected to the side of the rotating blocks away from the center of the mounting frame.

[0007] As a further embodiment of the present invention: the face-changing flipping component also includes a support frame installed on both sides of the positioning plate. The top of the support frame is provided with a rack. Both ends of the worm are fixedly connected with ratchet wheels. One end of the worm is rotatably connected to an outer ring through a bearing. A spur gear ring is installed on the outer wall of the outer ring. One side of the outer ring is rotatably connected to a pawl that meshes with the ratchet wheels through a rotating shaft. A torsion spring is engaged between the pawl and the rotating shaft connected to the outer ring through a slot.

[0008] As a further aspect of the present invention: the inner sides of both the rotating connecting block and the worm gear are provided with through holes that fit with the insertion rod.

[0009] As a further embodiment of the present invention: the outer connecting ring and the worm gear are rotatably connected by a bearing, and the outer connecting ring and the spur gear ring are fixedly connected by bolts.

[0010] As a further embodiment of the present invention: the number of pawls is set to multiple, and the multiple pawls are distributed at equal distances along the center of the outer ring.

[0011] As a further aspect of the present invention, the distance from the bottom end of the rack to the top of the support plate is greater than half the width of the mounting bracket.

[0012] As a further embodiment of the present invention: the supporting connector includes a telescopic cylinder installed on the top of the positioning plate and located below the positioning block. The bottom of the positioning block is provided with a connecting chamber. An I-shaped connecting block extending to the bottom of the connecting chamber is inserted into the inner side of the connecting chamber. The extended end of the telescopic cylinder is connected to the bottom of the I-shaped connecting block. The top of the I-shaped connecting block is provided with a second contact piece located inside the connecting chamber. The bottom of the inner wall of the connecting chamber is provided with a first contact piece located below the second contact piece. A side connecting frame is installed on the side of the positioning block near the center of the mounting frame. A normally open solenoid valve is installed on the top of the side connecting frame. A piston rod is provided at the bottom of the side connecting frame. An air cylinder connected to the positioning plate is provided on the outer side of the piston rod. A venting groove penetrating the piston rod is opened on the inner side of the piston rod.

[0013] As a further embodiment of the present invention: the second contact is electrically connected to a normally open solenoid valve via a wire, and the first contact is electrically connected to an external power supply via a wire.

[0014] As a further aspect of the present invention: the diameter of the I-shaped connecting block is equal to the diameter of the inner wall of the connecting chamber.

[0015] As a further embodiment of the present invention: a through hole is provided on one side of the side connecting frame, located below the normally open solenoid valve, and the vent groove is connected to the normally open solenoid valve through the through hole on the side connecting frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up a face-changing flipping component, as the mounting bracket moves upward, the spur gear ring will mesh with the rack. At this time, the spur gear ring will rotate along the rack, and the outer coupling ring will rotate relative to the worm. When the mounting bracket moves downward, the spur gear ring and the rack will mesh again. At this time, due to the engagement of the pawl and the ratchet, the ratchet will rotate synchronously with the spur gear ring as it rotates along the rack. This causes the fixture to rotate the workpiece that is being clamped and limited by 180 degrees, thereby changing the face of the workpiece. Afterward, as the mounting bracket moves downward, the workpiece can be placed on the top of the pallet. This process does not require repeated positioning of the workpiece, making the operation simple. It also prevents the position of the workpiece relative to the mounting bracket from changing during secondary positioning of the workpiece, further improving the milling accuracy.

[0018] 2. By setting up the support connector, the telescopic cylinder is activated. The telescopic cylinder pushes the I-shaped connecting block to move. During this process, the I-shaped connecting block moves relative to the connecting chamber, thus separating the second contact piece from the first contact piece. At this time, the normally open solenoid valve on the top of the side connecting frame opens. As the telescopic cylinder extends, the top of the I-shaped connecting block contacts the top of the inner wall of the connecting chamber. The connecting chamber then moves upward under the push of the I-shaped connecting block, thus moving the mounting frame upward. At this time, the piston rod moves upward relative to the air cylinder, and outside air, under negative pressure, passes through the normally open solenoid valve. The valve and vent groove enter below the piston rod. Similarly, when the telescopic cylinder retracts, the connecting chamber moves down synchronously with the I-shaped connecting block. When the workpiece falls to the top of the pallet, the telescopic cylinder continues to retract. At this time, the I-shaped connecting block moves down relative to the connecting chamber, so that the second contact piece contacts the first contact piece. At this time, the normally open solenoid valve is energized and closed, so that the air below the piston rod loses its flow space, thereby fixing the air cylinder and the piston rod relatively. This prevents the mounting bracket from moving up or down during the workpiece processing, further improving the stability of the workpiece. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0030] Please refer to Figures 1 to 8. In this embodiment of the invention, an AC generator decoupling shock-absorbing pulley milling device includes a base 1. A movable seat 2 is installed on the top of the base 1. A feed seat 3 is provided on one side of the movable seat 2 on the top of the base 1. A milling head body 4 is provided on one side of the feed seat 3 above the movable seat 2. A positioning plate 5 is installed on the top of the movable seat 2 below the milling head body 4. A support plate 7 is provided on the top of the positioning plate 5. Support connectors are provided on both sides of the support plate 7 on the top of the positioning plate 5. A mounting frame 6 is connected to the positioning plate 5 through the support connectors. A bidirectional lead screw 15 is provided on the outer wall of the mounting frame 6. A splicing rod 16 is sleeved on the outer side of the bidirectional lead screw 15. A limiting groove 14 is opened on one side of the mounting frame 6. The splicing rod 16 extends from the outer side of the mounting frame 6 through the limiting groove 14 to the inner side of the mounting frame 6. A clamp 13 is provided at one end of the splicing rod 16 and located inside the mounting frame 6. A flipping component that facilitates the connection of the mounting frame 6 is provided on one side of the clamp 13.

[0031] In this embodiment, the workpiece to be milled is first placed on the top of the pallet 7. Then, the bidirectional lead screw 15 is rotated, causing the splicing rod 16 to move horizontally along the bidirectional lead screw 15. This causes the two splicing rods 16 on the bidirectional lead screw 15 to move towards the center of the mounting frame 6, thereby causing the splicing rods 16 to drive the clamp 13 to move, thus clamping and fixing the workpiece on the pallet 7. Then, through the coordinated operation of the movable seat 2, the feed seat 3, and the milling head body 4, the milling head body 4 mills the top surface of the workpiece. After the top surface of the workpiece is machined, the support connector is activated. Through the operation of the support connector, the mounting frame 6 is moved upward as a whole, thereby increasing the vertical distance between the mounting frame 6 and the pallet 7. As the mounting frame 6 moves upward, the spur gear ring 31 will mesh with the rack 12. At this time, the mounting frame 6 continues to move upward, and the spur gear ring 31 will move along the rack 12. When rack 12 rotates, the pawl 32 cannot limit the ratchet 29, causing the outer ring 30 to rotate relative to the worm 21. When the mounting bracket 6 moves down, the spur gear ring 31 and rack 12 mesh again. At this time, due to the engagement between the pawl 32 and ratchet 29, the ratchet 29 rotates synchronously with the spur gear ring 31 as it rotates along the rack 12. This causes the ratchet 29 to drive the worm 21 to rotate. When the worm 21 rotates, it drives the insert rod 10 to rotate through the worm wheel 9. This causes the clamp 13 to rotate the clamped and limited workpiece by 180 degrees, thereby changing the surface of the workpiece. Afterwards, as the mounting bracket 6 moves down, the workpiece can be placed on the top of the pallet 7. This process does not require repeated positioning of the workpiece, making the operation simple. It also prevents the workpiece from changing its position relative to the mounting bracket 6 during secondary positioning, further improving the milling accuracy.

[0032] Please refer to Figures 2, 3, 4, 7, and 8. The flip-over component includes rotating blocks 8 installed on both sides of the mounting frame 6. The rotating blocks 8 are rotatably connected to the mounting frame 6 via bearings. One end of the clamp 13 is fixed with a rod 10 that passes through the rotating blocks 8. A worm gear 9 is fixedly connected to the side of the rotating blocks 8 away from the center of the mounting frame 6. A positioning block 22 is installed at the bottom of the mounting frame 6. A worm 21 that meshes with the worm gear 9 is rotatably connected to one side of the positioning block 22 via a bearing.

[0033] The flipping component also includes support frames 11 installed on both sides of the positioning plate 5. A rack 12 is provided at the top of the support frame 11. Ratchets 29 are fixedly connected to both ends of the worm 21. An outer ring 30 is rotatably connected to one end of the worm 21 through a bearing. A spur gear ring 31 is installed on the outer wall of the outer ring 30. A pawl 32 that meshes with the ratchet 29 is rotatably connected to one side of the outer ring 30 through a rotating shaft. A torsion spring 33 is engaged between the pawl 32 and the rotating shaft connected to the outer ring 30 through a slot.

[0034] The inner sides of the rotating connecting block 8 and the worm gear 9 are provided with through holes that fit the insert rod 10. The outer connecting ring 30 and the worm 21 are rotatably connected by bearings. The outer connecting ring 30 and the spur gear ring 31 are fixedly connected by bolts. There are multiple pawls 32, and the multiple pawls 32 are evenly distributed along the center of the outer connecting ring 30. The distance from the bottom of the rack 12 to the top of the support plate 7 is greater than half the width of the mounting bracket 6.

[0035] In this embodiment, the mounting bracket 6 is moved upward by the operation of the supporting connector, thereby increasing the vertical distance between the mounting bracket 6 and the support plate 7. As the mounting bracket 6 moves upward, the spur gear ring 31 engages with the rack 12. When the mounting bracket 6 continues to move upward, the spur gear ring 31 rotates along the rack 12. At this time, since the pawl 32 cannot limit the ratchet 29, the outer coupling ring 30 rotates relative to the worm gear 21. When the mounting bracket 6 moves downward, the spur gear ring 31 engages with the rack 12 again. At this time, due to the engagement of the pawl 32 and the ratchet 29, the spur gear ring 31 rotates along the rack 12. When the rack 12 rotates, the ratchet 29 rotates synchronously with the spur gear ring 31, thereby causing the ratchet 29 to drive the worm 21 to rotate. When the worm 21 rotates, it drives the insert rod 10 to rotate through the worm wheel 9, thereby causing the clamp 13 to rotate the workpiece that is clamped and limited by 180 degrees, thus performing a face-changing process on the workpiece. Afterwards, as the mounting bracket 6 moves down, the workpiece can be placed on the top of the pallet 7. This process does not require repeated positioning of the workpiece, making the operation simple. It also prevents the position of the workpiece relative to the mounting bracket 6 from changing during secondary positioning of the workpiece, further improving the accuracy of milling.

[0036] Please refer to Figures 2, 3, 5, and 6. The supporting connector includes a telescopic cylinder 18 installed on the top of the positioning plate 5 and located below the positioning block 22. A connecting chamber 19 is provided at the bottom of the positioning block 22. An I-shaped connecting block 20 extending to the bottom of the connecting chamber 19 is inserted into the inner side of the connecting chamber 19. The extended end of the telescopic cylinder 18 is connected to the bottom of the I-shaped connecting block 20. A second contact piece 26 located inside the connecting chamber 19 is provided at the top of the I-shaped connecting block 20. A first contact piece 23 located below the second contact piece 26 is provided at the bottom of the inner wall of the connecting chamber 19. A side connecting frame 24 is installed on the side of the positioning block 22 near the center of the mounting bracket 6. A normally open solenoid valve 25 is installed at the top of the side connecting frame 24. A piston rod 27 is provided at the bottom of the side connecting frame 24. An air cylinder 17 connected to the positioning plate 5 is provided on the outer side of the piston rod 27. A venting groove 28 penetrating the piston rod 27 is provided on the inner side of the piston rod 27.

[0037] The second contact 26 is electrically connected to the normally open solenoid valve 25 via a wire, the first contact 23 is electrically connected to an external power supply via a wire, the diameter of the I-shaped connecting block 20 is equal to the inner wall diameter of the connecting chamber 19, a through hole is provided on one side of the side connecting frame 24 below the normally open solenoid valve 25, and the venting groove 28 is connected to the normally open solenoid valve 25 through the through hole on the side connecting frame 24.

[0038] In this embodiment, the telescopic cylinder 18 is activated, which pushes the I-shaped connecting block 20 to move. During this process, the I-shaped connecting block 20 moves relative to the connecting chamber 19, thereby separating the second contact piece 26 from the first contact piece 23. At this time, the normally open solenoid valve 25 on the top of the side connecting frame 24 will open. As the telescopic cylinder 18 extends, the top of the I-shaped connecting block 20 contacts the top of the inner wall of the connecting chamber 19. At this time, the connecting chamber 19 will move upward under the push of the I-shaped connecting block 20, thereby moving the mounting frame 6 upward. At this time, the piston rod 27 moves upward relative to the air cylinder 17, and the outside air passes through the normally open solenoid valve 25 under negative pressure. 5. The venting groove 28 enters below the piston rod 27. Similarly, when the telescopic cylinder 18 retracts, the connecting chamber 19 will move down synchronously with the I-shaped connecting block 20. When the workpiece falls to the top of the pallet 7, the telescopic cylinder 18 continues to retract. At this time, the I-shaped connecting block 20 will move down relative to the connecting chamber 19, so that the second contact piece 26 contacts the first contact piece 23. At this time, the normally open solenoid valve 25 is energized and closed, so that the air below the piston rod 27 loses its flow space, thereby fixing the air cylinder 17 and the piston rod 27 relatively. This prevents the mounting bracket 6 from moving up or down during the workpiece processing, further improving the stability of the workpiece.

[0039] The working principle of this invention is as follows: First, the workpiece to be milled is placed on the top of the pallet 7. Then, the double-acting lead screw 15 is rotated. The rotation of the double-acting lead screw 15 causes the splicing rod 16 to move horizontally along the double-acting lead screw 15, thereby causing the two splicing rods 16 on the double-acting lead screw 15 to move towards the center of the mounting frame 6. This causes the splicing rods 16 to drive the clamp 13 to move, thereby clamping and fixing the workpiece on the pallet 7. Then, through the coordinated operation of the movable seat 2, the feed seat 3, and the milling head body 4, the milling head body 4 mills the top surface of the workpiece. The telescopic cylinder 18 is activated. At this time, the telescopic cylinder 18 pushes the I-shaped connecting block 20 to move. During this process, the I-shaped connecting block... The connecting block 20 moves relative to the connecting chamber 19, thereby separating the second contact piece 26 from the first contact piece 23. At this time, the normally open solenoid valve 25 on the top of the side connecting frame 24 will open. As the telescopic cylinder 18 extends, the top of the I-shaped connecting block 20 contacts the top of the inner wall of the connecting chamber 19. At this time, the connecting chamber 19 will move upward under the push of the I-shaped connecting block 20, thereby moving the mounting frame 6 upward. At this time, the piston rod 27 moves upward relative to the air cylinder 17. Under the action of negative pressure, outside air enters below the piston rod 27 through the normally open solenoid valve 25 and the air vent 28. As the mounting frame 6 moves upward, the spur gear ring 31 will mesh with the rack 12. At this time, the mounting frame 6 continues to move upward, and the spur gear ring 31... The spur gear ring 31 rotates along the rack 12. Since the pawl 32 cannot limit the ratchet 29, the outer ring 30 rotates relative to the worm 21. When the mounting bracket 6 moves downwards, the spur gear ring 31 meshes with the rack 12 again. Due to the engagement of the pawl 32 and the ratchet 29, the ratchet 29 rotates synchronously with the spur gear ring 31 as it rotates along the rack 12. This causes the ratchet 29 to drive the worm 21 to rotate. The worm 21, in turn, drives the insert rod 10 to rotate via the worm wheel 9. This causes the clamp 13 to rotate the clamped and limited workpiece by 180 degrees, thus performing a face-changing process. Afterwards, as the mounting bracket 6 moves downwards, the workpiece can be placed... At the top of the pallet 7, this process eliminates the need for repeated workpiece positioning, simplifying operation and preventing changes in the workpiece's position relative to the mounting bracket 6 during secondary workpiece positioning. This further improves milling accuracy. When the workpiece falls to the top of the pallet 7, the telescopic cylinder 18 continues to retract. At this time, the I-shaped connecting block 20 moves downward relative to the connecting chamber 19, causing the second contact piece 26 to contact the first contact piece 23. Meanwhile, the normally open solenoid valve 25 is energized and closed, thus depriving the air below the piston rod 27 of its flow space. This fixes the air cylinder 17 and the piston rod 27 relatively, preventing the mounting bracket 6 from moving upward or downward during workpiece processing and further improving workpiece stability.

[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
