Description

Technical Field

[0001] This invention belongs to the field of machining technology, specifically a through-hole device for machining four-way connectors. Background Technology

[0002] As a key component in fluid transmission systems, the four-way connector is widely used in various industrial, construction and civil fields. The main function of the four-way connector is to connect four pipes to realize the diversion and merging of fluids. In order to achieve this function, precise through holes must be designed and machined inside the connector to ensure that the fluid can flow between the four pipes.

[0003] A search revealed a Chinese patent with publication number CN211803969U that discloses a pipe opening device, which includes a fixing component, a hole saw, and a feeding rotary drive mechanism. A horizontally arranged lower support frame is fixed to the top of one side of the fixing component, and a through hole is opened in the middle of the lower support frame. The hole saw is slidably arranged in the through hole. An upper support frame is fixedly connected to the top of the lower support frame through several columns, and a feeding rotary drive mechanism is arranged between each column. The feeding rotary drive mechanism drives the hole saw to rotate while simultaneously driving the hole saw to move downward.

[0004] In the above technology, the design of the fixing components enables the entire hole-opening device to be stably fixed on the pipe, ensuring the stable operation of the hole-opening process and thus improving the accuracy of the hole-opening. However, due to the fixed structure of the hole-opening device, it is impossible to open through holes of different diameters and cannot adapt to pipe processing of different diameters. This results in poor versatility of the hole-opening device, requiring frequent replacement of cutting tools or adjustment of equipment, which increases production costs and time costs.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The through-hole device for machining four-way connectors according to the present invention performs preliminary machining of the four-way connector through the design of a roughing mechanism. A first cylinder drives the drill bit to move upward, allowing the drill bit to pass through the machining hole and drill the inside of the four-way connector. Then, a finishing mechanism further processes the four-way connector. A hydraulic cylinder drives the turntable to move downward, thereby moving the milling cutter downward and allowing the milling cutter to move into the through hole drilled by the drill bit. Then, a first motor drives the first lead screw to rotate, thereby moving the moving block and then moving the milling cutter, so that the milling cutter contacts the edge of the through hole, thereby milling the four-way connector. At the same time, a second motor drives the drive gear to rotate, thereby driving the turntable to rotate, thereby driving the milling cutter to rotate. With the cooperation of the first motor and the second motor, the milling cutter can mill through holes of different diameters and can mill four-way connectors of different diameters without changing the tool or adjusting the equipment structure, thus improving the versatility and flexibility of the equipment.

[0023] 2. The through-hole device for machining a four-way connector described in this invention, through a vacuum cleaner design, can absorb the debris generated during the machining process of the four-way connector. When the vacuum cleaner is turned on, a negative pressure is generated inside the machining chamber. At this time, air flows into the machining chamber through the through-hole on the four-way connector. During this process, debris generated during drilling or milling is also carried by the flowing air through the machining hole into the machining chamber, and then enters the vacuum cleaner through the slag suction channel and suction pipe. This design can prevent the accumulation of debris in the machining area, reduce the interference of debris on the machining process, and thus ensure machining accuracy. At the same time, this design can also prevent the generation of large amounts of debris in the working environment during machining. The controlled dust dispersion not only facilitates subsequent cleaning but also prevents excessive dust from adversely affecting the health of workers. Furthermore, when the finishing mechanism starts working, the hydraulic cylinder drives the turntable to move downwards, which in turn moves the first rack downwards, causing the first gear to rotate, which in turn drives the second lead screw to rotate. When the second lead screw rotates, it moves the moving plate, thus moving the roughing mechanism into the transfer chamber. This not only allows the dust generated during milling to be absorbed by the vacuum cleaner more easily but also prevents the drill bit and the first machining motor in the roughing mechanism from being in contact with and rubbing against the dust for a long time, thereby ensuring the service life of each structure in the roughing mechanism.

[0024] 3. The through-hole device for processing four-way connectors according to the present invention, through the design of the clamping mechanism, can stably clamp the four-way connector on the placement seat, thereby ensuring processing accuracy. A third motor drives the second gear to rotate, thereby causing two second racks to move synchronously in opposite directions, which in turn causes two first clamping plates to move synchronously in opposite directions. When the two first clamping plates approach each other, they clamp the four-way connector. The first clamping plates can cover the connector through-holes on both sides of the four-way connector. Thus, when the vacuum cleaner is turned on, outside air can only flow into the four-way connector through the through-hole at the top of the connector, thereby restricting the airflow inlet, making the airflow entering the vacuum cleaner more concentrated, and increasing the airflow velocity, thereby improving the vacuum cleaner's absorption effect on debris. Additionally, when the first clamping plate contacts the four-way connector, the second rack continues to move via the third motor, thereby moving the support sleeve. At this time, the spring and damper inside the support sleeve will contract, and the end of the support sleeve will gradually move closer to the first clamping plate. As the end of the support sleeve moves closer to the first clamping plate, the connecting rod will rotate, thereby moving the second slider, which in turn moves the third rack. When the third rack moves, it will drive the third gear to rotate. During the rotation of the third gear, it will drive the pressure rod to move, thereby moving the pressure block to move and allowing the pressure block to contact the four-way connector. The three pressure plates on the first clamping plate squeeze the four-way connector in different directions, thereby further improving the stability of the first clamping plate in holding the four-way connector.

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] like Figures 1 to 15As shown in the embodiment of the present invention, a through-hole device for machining a four-way connector includes: a worktable 1; a support frame 2, fixedly connected to the top of the worktable 1; a placement seat 3, located at the center of the top of the worktable 1; a machining cavity 301 is provided in the center of the placement seat 3, and a roughing mechanism 4 is provided in the machining cavity 301. The roughing mechanism 4 includes a moving plate 401, a first cylinder 402, and a drill bit 404. The moving plate 401 is slidably connected to the placement seat 3. The first cylinder 402 is fixedly connected to one end of the top of the moving plate 401. A first machining motor 403 is fixedly connected to the output end of the first cylinder 402. The drill bit 404 is fixedly connected to the output end of the first machining motor 403. The placement seat 3 has a machining hole 302 located at the center of the top of the machining cavity 301. A finishing mechanism 5 is provided on the top of the support frame 2. The finishing mechanism 5 includes a hydraulic cylinder 501, a turntable 504, and a milling cutter 511. The hydraulic cylinder 501 is located directly above the placement seat 3 and is fixedly connected to the support frame 2. A U-shaped frame 502 is fixedly connected to the output end of 501. A collar 503 is fixedly connected to the bottom of the U-shaped frame 502. A turntable 504 is rotatably connected inside the collar 503. One end of the turntable 504 has a first through groove 505. A first motor 506 is fixedly connected to one end of the first through groove 505. A first lead screw 507 is fixedly connected to the output end of the first motor 506. A moving block 508 is threadedly connected to one end of the first lead screw 507. The moving block 508 is slidably connected to the first through groove 505. An electric telescopic rod 509 is fixedly connected to the bottom of block 508. A second processing motor 510 is fixedly connected to the output end of the electric telescopic rod 509. A milling cutter 511 is fixedly connected to the output end of the second processing motor 510. A second motor 512 is fixedly connected to one end of the outer wall of collar 503. A drive gear 513 is fixedly connected to the output end of the second motor 512. A toothed ring 514 is fixedly connected to the side wall of turntable 504 above collar 503. The drive gear 513 meshes with the toothed ring 514.

[0044] In this embodiment, when processing the four-way connector, the four-way connector is first fixed on the placement base 3, and located directly above the processing hole 302 of the placement base 3. At this point, through-hole processing can begin. First, the roughing mechanism 4 performs preliminary processing on the four-way connector. During operation, the first cylinder 402 is opened, driving the drill bit 404 upwards. Simultaneously, the first processing motor 403 is opened, driving the drill bit 404 to rotate. Under the combined action of the first cylinder 402 and the first processing motor 403, the drill bit 404 can smoothly pass through the processing hole 302 and drill the four-way connector. When the drill bit 404 completes drilling... Then, precise machining can be performed through the finishing mechanism 5. During operation, first, the hydraulic cylinder 501 is opened, which drives the U-shaped frame 502 to move downward, thereby driving the collar 503 to move downward, and then driving the turntable 504 to move downward. During the downward movement of the turntable 504, the milling cutter 511 will move downward. When the bottom of the milling cutter 511 moves to the height of the top of the four-way connector, the hydraulic cylinder 501 is closed, fixing the turntable 504 at that height. Then, the second machining motor 510 is turned on. Driven by the second machining motor 510, the milling cutter 511 will rotate. At the same time, the electric telescopic rod 509 is opened, allowing the milling cutter 511 to move to the drill bit 404. Inside the drilled through hole, the electric telescopic rod 509 drives the milling cutter 511 to move up and down. The movement of the milling cutter 511 is relatively small, allowing for more precise machining. Meanwhile, the hydraulic cylinder 501 drives the milling cutter 511 to move up and down, with a larger movement range, primarily to quickly move the milling cutter 511 from a higher position to the vicinity of the four-way connector. When the milling cutter 511 enters the through hole drilled by the drill bit 404, the first motor 506 is activated, driving the first lead screw 507 to rotate. This rotates the moving block 508, which in turn moves the electric telescopic rod 509, thus moving the milling cutter 511 to contact the edge of the through hole. This allows the milling cutter 511 to smoothly mill the four-way connector. Then, the second motor 512 is turned on, and under the drive of the second motor 512, the drive gear 513 rotates, thereby driving the gear ring 514 to rotate, which in turn drives the turntable 504 to rotate. When the turntable 504 rotates, it drives the milling cutter 511 to rotate around the axis of the turntable 504, so that the milling cutter 511 can perform fine machining on the through hole. With the cooperation of the first motor 506 and the second motor 512, the milling cutter 511 can mill through holes of different diameters, and can also mill four-way connectors of different diameters without changing the tool or adjusting the equipment structure, thus improving the versatility and flexibility of the equipment.

[0045] like Figures 1 to 8As shown, one end of the worktable 1 is provided with a second through groove 101, and a second lead screw 102 is rotatably connected in the second through groove 101. One end of the placement seat 3 is provided with a transfer cavity 303, which communicates with the processing cavity 301. One end of the moving plate 401 extends to the outside of the placement seat 3 through the transfer cavity 303 and is fixedly connected with a connecting ear 405. The connecting ear 405 is threadedly connected to the second lead screw 102. One end of the second lead screw 102 is fixedly connected with a first gear 103. The worktable 1 is provided with a groove 104 at one end of the second through groove 101. One end of the side wall of the collar 503 is fixedly connected with a first connecting frame 515. A first rack 516 is fixedly connected to the bottom of the frame 515. The first rack 516 is slidably connected to the groove 104 and meshes with the first gear 103. A slag suction channel 304 is provided at one end of the placement seat 3. One end of the slag suction channel 304 is connected to the processing chamber 301. A vacuum cleaner 6 is provided at one end of the workbench 1. The input end of the vacuum cleaner 6 is connected to a slag suction pipe 601. One end of the slag suction pipe 601 is connected to the slag suction channel 304. A first cover plate 406 is fixedly connected to the top of the moving plate 401 at one end of the processing chamber 301. A second cover plate 407 is fixedly connected to the other end of the moving plate 401 outside the placement seat 3.

[0046] In this embodiment, during the machining of the four-way connector by the drill bit 404 and the milling cutter 511, a lot of debris is generated. To avoid the accumulation of debris from adversely affecting the machining process, the vacuum cleaner 6 needs to be turned on. When the vacuum cleaner 6 is turned on, a negative pressure is generated inside the machining chamber 301. At this time, air flows into the machining chamber 301 through the through hole on the four-way connector. During this process, the debris generated by the drill bit 404 or the milling cutter 511 also enters the machining chamber 301 through the machining hole 302 along with the flowing air, and enters the vacuum cleaner 6 through the slag suction channel 304 and the slag suction pipe 601. This design avoids the accumulation of debris in the processing area, reducing the interference of debris on the processing process and thus ensuring processing accuracy. Simultaneously, this design prevents the generation of large amounts of dust in the working environment during processing, facilitating subsequent cleaning and preventing the adverse health effects of excessive dust on workers. Furthermore, when the finishing mechanism 5 is in operation, the hydraulic cylinder 501 is opened, driving the collar 503 downwards, which in turn moves the first connecting frame 515 downwards, and consequently, the first rack 516 downwards. As the first rack 516 moves downwards... During the process, the first gear 103 will rotate, which in turn will drive the second lead screw 102 to rotate. The second lead screw 102 is threadedly connected to the connecting lug 405 at one end of the moving plate 401. Therefore, when the second lead screw 102 rotates, it will drive the moving plate 401 to move, thereby driving the first cylinder 402, the first machining motor 403, and the drill bit 404 to move, allowing the first cylinder 402, the first machining motor 403, and the drill bit 404 to move into the transfer chamber 303. This not only allows the debris generated by the milling cutter 511 to be absorbed by the vacuum cleaner 6 more smoothly, but also avoids the drill bit 4 in the roughing mechanism 4 from being removed. Structures such as 04 and the first machining motor 403 are in contact with and rub against the chips for a long time, thereby ensuring the service life of each structure in the roughing mechanism 4. In addition, the design of the first cover plate 406 can cover the connection between the transfer cavity 303 and the machining cavity 301, thereby preventing the chips generated by the milling cutter 511 during machining from entering the transfer cavity 303 and drifting to the outside of the placement seat 3. The design of the second cover plate 407 can cover the connection between the transfer cavity 303 and the outside, thereby preventing the chips generated by the drill bit 404 during machining from drifting to the outside of the placement seat 3 through the transfer cavity 303, thus affecting subsequent cleaning.

[0047] like Figures 11 to 14As shown, it also includes a clamping mechanism 7, which includes a third motor 701, a second cylinder 707, and a first clamping plate 708. The third motor 701 is fixedly connected to the bottom of the workbench 1 and is located directly below the placement seat 3. A rotating shaft 702 is fixedly connected to the output end of the third motor 701. A second gear 703 is fixedly connected to the bottom of the rotating shaft 702. A second rack 704 is meshed with both ends of the second gear 703. A second connecting frame 705 is fixedly connected to one end of the second rack 704. 05 extends to the top of the workbench 1 and is slidably connected to the workbench 1. A first slider 706 is fixedly connected to one end of the top of the second connecting frame 705. A second cylinder 707 is fixedly connected to the top of the first slider 706. A support sleeve 709 is fixedly connected to the output end of the second cylinder 707. A first clamping plate 708 is provided at one end of the support sleeve 709. A spring 710 is fixedly connected to one end of the inner wall of the support sleeve 709. A damper 711 is fixedly connected to the support sleeve 709 inside the spring 710. 10 and damper 711 are both fixedly connected to one end of a slide rod 712. The slide rod 712 is slidably connected to the support sleeve 709. The first clamping plate 708 is fixedly connected to one end of the slide rod 712. Three L-shaped plates 713 are fixedly connected to the side wall of the first clamping plate 708. A pressure rod 714 is slidably connected to one end of the L-shaped plate 713. A pressure block 715 is fixedly connected to one end of the pressure rod 714. A protrusion 716 is fixedly connected to one end of the side wall of the pressure rod 714. A plurality of teeth 717 are provided at one end of the protrusion 716. The L-shaped plate 713 is located at... The pressure rod 714 is rotatably connected to a third gear 718 at one end. The third gear 718 meshes with the tooth groove 717. The first clamping plate 708 is provided with three sliding grooves 719 on the side wall of one end of the slide rod 712. The second slider 720 is slidably connected in the sliding groove 719. The second slider 720 is fixedly connected to a third rack 721 at one end. The third rack 721 meshes with the third gear 718. The outer wall of the support sleeve 709 is rotatably connected to three connecting rods 722 at one end. The connecting rods 722 are rotatably connected to the slider at one end.

[0048] In this embodiment, the clamping mechanism 7 is designed to clamp and fix the four-way connector, ensuring its stable fixation on the placement base 3 and thus guaranteeing processing accuracy. When processing the four-way connector, it is first placed on the placement base 3 with the connectors on both sides facing the two first clamping plates 708. Then, the third motor 701 is activated. Driven by the first motor 506, the rotating shaft 702 rotates, thereby driving the second gear 703 to rotate, which in turn drives the two second racks 704 to move synchronously in opposite directions. During the movement of the second racks 704, the second connecting frame 705 moves, which in turn moves the first slider 706, which in turn moves the second cylinder 707. When cylinder 7 moves, it moves the support sleeve 709, which in turn moves the slide rod 712, and then the first clamping plate 708. When the two first clamping plates 708 approach each other, they clamp the four-way connector. The first clamping plates 708 are circular. When the two first clamping plates 708 contact the four-way connector, they cover the through holes on both sides of the four-way connector. This way, when the vacuum cleaner 6 is turned on, outside air can only flow into the four-way connector through the through hole at the top of the four-way connector, thus restricting the airflow inlet, making the airflow entering the vacuum cleaner 6 more concentrated, and increasing the airflow velocity, thereby improving the vacuum cleaner 6's absorption effect on debris. During the clamping process, the second cylinder 707 needs to drive the support sleeve 709 to move up and down, thereby adjusting the first... The height of the clamping plate 708 ensures that the axis of the second clamping plate 804 coincides with the axes of the connectors on both sides of the four-way connector. After the first clamping plate 708 contacts the four-way connector, the third motor 701 drives the second gear 703 to rotate, thereby driving the second rack 704 to continue moving, which in turn drives the support sleeve 709 to continue moving. Since the first clamping plate 708 is in contact with the four-way connector at this time, its position will not change. Thus, driven by the third motor 701, the end of the support sleeve 709 will gradually approach the first clamping plate 708. At the same time, the spring 710 and damper 711 inside the support sleeve 709 will gradually contract. As the end of the support sleeve 709 gradually approaches the first clamping plate 708, it will drive the three connecting rods 722 to rotate. When rod 722 rotates, it drives the second slider 720 to move within the groove 719. The second slider 720 moves in a direction away from the center of the first clamping plate 708. As the second slider 720 moves, it drives the third rack 721 to move, thereby driving the third gear 718 to rotate. The third gear 718 meshes with the tooth groove 717 on the protrusion 716, and the protrusion 716 is fixedly connected to the pressure rod 714. Therefore, when the third gear 718 rotates, it drives the pressure rod 714 to move. The pressure rod 714 and the third rack 721 are located on opposite sides of the third gear 718, and thus move in opposite directions. The third rack 721 moves away from the center of the first clamping plate 708 along with the second slider 720.Therefore, the pressure rod 714 moves towards the center of the first clamping plate 708. As the pressure rod 714 moves, it drives the pressure block 715 to move, causing the pressure block 715 to contact the four-way connector. The three pressure rods 714 are evenly distributed in a circular array on the first clamping plate 708. Therefore, when the three pressure blocks 715 contact the four-way connector, they can firmly clamp the four-way connector, thereby improving clamping stability.

[0049] like Figure 3 As shown, the workbench 1 has a third through groove 105 at both ends. The third through groove 105 is slidably connected to the second connecting frame 705. The workbench 1 is fixedly connected to a support plate 106 at a position adjacent to the third through groove 105. The top of the support plate 106 is fixedly connected to a support rod 107. The support rod 107 is slidably connected to the first slider 706.

[0050] In this embodiment, the design of the third through slot 105 allows the second connecting frame 705 to pass smoothly through the workbench 1 and slide together with the workbench 1. The design of the support plate 106 and the support rod 107 can support the first slider 706, thereby making the first slider 706 more stable when moving, and thus ensuring the stability of the first clamping plate 708 when moving.

[0051] like Figure 3 and Figure 15 As shown, it also includes a flipping mechanism 8, which includes a third cylinder 801, a fourth cylinder 803, and a second clamping plate 804. There are two third cylinders 801, which are respectively located at the top ends of the placement base 3. The output end of the third cylinder 801 is fixedly connected to a flipping motor 802, and the output end of the flipping motor 802 is fixedly connected to a fourth cylinder 803. The fourth cylinder 803 is perpendicular to the third cylinder 801, and the output end of the fourth cylinder 803 is fixedly connected to the second clamping plate 804.

[0052] In this embodiment, the flipping mechanism 8 allows for the rotation of the four-way connector, eliminating the need for manual rotation during processing and preventing accidental injury from the milling cutter 511 or other equipment. During operation, the third cylinder 801 is first opened, driving the second clamping plate 804 to move up and down until its center height aligns with the center height of the four-way connector. Then, the two fourth cylinders 803 are opened, driving the two second clamping plates 804 to move synchronously in opposite directions, bringing them into contact with and clamping the two sides of the four-way connector. Finally, the third cylinder 801 is opened again, allowing the four-way connector to rotate smoothly. Cylinder 801 drives the second clamping plate 804 to move upward, thereby increasing the space for the four-way connector to flip. Then, the flipping motor 802 is turned on. Driven by the flipping motor 802, the second clamping plate 804 will rotate, thereby driving the four-way connector to rotate, thus realizing the flipping of the four-way connector. In actual use, anti-slip pads can be set on the second clamping plate 804 to increase the friction between the second clamping plate 804 and the four-way connector, thereby preventing the second clamping plate 804 from falling off when driving the four-way connector to flip. In addition, during the processing of the four-way connector, the second clamping plate 804 can also be driven by the fourth cylinder 803 to clamp the four-way connector, thereby further improving the stability of the four-way connector during processing.

[0053] Working principle: When processing the four-way connector, first place the four-way connector on the placement seat 3. The four-way connector should be placed directly above the processing hole 302, with the connectors on both sides facing the two first clamping plates 708 respectively. At this time, the third motor 701 can be turned on. Driven by the first motor 506, the rotating shaft 702 will rotate, thereby driving the second gear 703 to rotate, which in turn drives the two second racks 704 to move synchronously in opposite directions. During the movement of the second racks 704, the second connecting frame 705 will move, which in turn drives the first slider 706 to move, which in turn drives the second cylinder 707 to move. When the second cylinder 707 moves, it will drive the support sleeve 709 to move, which in turn drives the slide rod 712 to move, which in turn drives... The first clamping plate 708 moves, and when the two first clamping plates 708 approach each other, they can clamp the four-way connector. During the clamping process, the second cylinder 707 drives the support sleeve 709 to move up and down, thereby adjusting the height of the first clamping plates 708 so that the axis of the second clamping plate 804 coincides with the axis of the connectors on both sides of the four-way connector. After the first clamping plates 708 contact the four-way connector, the third motor 701 drives the second gear 703 to rotate, thereby driving the second rack 704 to continue moving, which in turn drives the support sleeve 709 to continue moving. As the end of the support sleeve 709 gradually approaches the first clamping plate 708, the spring 710 and damper 711 inside the support sleeve 709 will gradually contract, which will simultaneously drive the support sleeve... The three connecting rods 722 at one end of the cylinder 709 rotate. When the connecting rods 722 rotate, they drive the second slider 720 to move within the groove 719. The second slider 720 moves in a direction away from the center of the first clamping plate 708. When the second slider 720 moves, it drives the third rack 721 to move, thereby driving the third gear 718 to rotate. The third gear 718 meshes with the tooth groove 717 on the protrusion 716, and the protrusion 716 is fixedly connected to the pressure rod 714. Therefore, when the third gear 718 rotates, it drives the pressure rod 714 to move. The pressure rod 714 and the third rack 721 are located on opposite sides of the third gear 718, and thus move in opposite directions. The third rack 721 moves along with the second slider 709. The pressure rod 714 moves towards the center of the first clamping plate 708, moving away from the center of the first clamping plate 708. As the pressure rod 714 moves, it drives the pressure block 715 to move, bringing it into contact with the four-way connector. The three pressure rods 714 are evenly distributed in a circular array on the first clamping plate 708. Therefore, when the three pressure blocks 715 contact the four-way connector, they can firmly clamp the connector, improving clamping stability. Once the four-way connector is fixed, through-hole machining can begin. First, the roughing mechanism 4 performs preliminary machining on the four-way connector. During operation, the first cylinder 402 is opened, driving the drill bit 404 upwards, while simultaneously activating the first machining motor 403.The first machining motor 403 drives the drill bit 404 to rotate. Under the combined action of the first cylinder 402 and the first machining motor 403, the drill bit 404 can smoothly pass through the machining hole 302 and drill the four-way connector. When the drill bit 404 finishes drilling, it can be precisely machined by the finishing mechanism 5. During operation, the hydraulic cylinder 501 is opened first, and the hydraulic cylinder 501 drives the U-shaped frame 502 to move downward, thereby driving the collar 503 to move downward, and then driving the turntable 504 to move downward. During the downward movement of the turntable 504, the milling cutter 511 will move downward. When the bottom of the milling cutter 511 moves to the height of the top of the four-way connector, the hydraulic cylinder 501 is closed, and the turntable 504 is fixed at that height. Next, the second machining motor 510 is turned on. Driven by the second machining motor 510, the milling cutter 511 rotates. Simultaneously, the electric telescopic rod 509 is opened, allowing the milling cutter 511 to move into the through hole drilled by the drill bit 404. The electric telescopic rod 509 drives the milling cutter 511 to move up and down, with a smaller range of movement, allowing for more precise machining. The hydraulic cylinder 501 drives the milling cutter 511 to move up and down, with a larger range of movement, mainly to quickly move the milling cutter 511 from a higher position to the vicinity of the four-way connector. When the milling cutter 511 enters the through hole drilled by the drill bit 404, the first motor 506 is turned on, driving the first lead screw 507 to rotate, thereby... The moving block 508 moves, which in turn moves the electric telescopic rod 509, thereby moving the milling cutter 511 so that it contacts the edge of the through hole, allowing the milling cutter 511 to smoothly mill the four-way connector. Then, the second motor 512 is turned on, and under its drive, the drive gear 513 rotates, which in turn rotates the gear ring 514, which in turn rotates the turntable 504. As the turntable 504 rotates, it causes the milling cutter 511 to rotate around its axis, allowing it to perform fine machining on the through hole. With the combined action of the first motor 506 and the second motor 512, the milling cutter 511 can mill through holes of different diameters and simultaneously mill four-way connectors of different diameters. The machining process eliminates the need to change tools or adjust equipment structure, improving the equipment's versatility and flexibility. During the machining of the four-way connector using drill bit 404 and end mill 511, a lot of chips are generated. To prevent chip accumulation from adversely affecting the machining process, the vacuum cleaner 6 needs to be turned on. When the vacuum cleaner 6 is turned on, a negative pressure is generated inside the machining chamber 301. At this time, air flows into the machining chamber 301 through the through hole on the four-way connector. During this process, the chips generated by drill bit 404 or end mill 511 are also carried by the flowing air through the machining hole 302 into the machining chamber 301, and then into the vacuum cleaner 6 through the chip suction channel 304 and the chip suction pipe 601. This design can prevent chip accumulation in the machining area.This design reduces the interference of debris on the machining process, thus ensuring machining accuracy. It also avoids generating large amounts of dust in the working environment during machining, facilitating subsequent cleaning and preventing the adverse health effects of excessive dust on workers. Furthermore, when the finishing mechanism 5 is in operation, the hydraulic cylinder 501 is opened, driving the collar 503 downwards, which in turn moves the first connecting frame 515 downwards, and consequently the first rack 516 downwards. During the downward movement of the rack 516, the first gear 103 rotates, which in turn rotates the second lead screw 102. The second lead screw 102 is threadedly connected to the connecting lug 405 at one end of the moving plate 401. Therefore, when the second lead screw 102 rotates, it moves the moving plate 401, thereby moving the first cylinder 402, the first machining motor 403, and the drill. The head 404 moves, allowing the first cylinder 402, the first machining motor 403, and the drill bit 404 to move into the transfer chamber 303. This not only allows the debris generated during milling by the end mill 511 to be more easily absorbed by the vacuum cleaner 6, but also prevents the drill bit 404 and the first machining motor 403 in the roughing mechanism 4 from prolonged contact and friction with debris, thus ensuring the service life of each structure in the roughing mechanism 4. Furthermore, the design of the first cover plate 406 covers the connection between the transfer chamber 303 and the machining chamber 301, preventing debris generated by the end mill 511 from entering the transfer chamber 303 and scattering outside the placement seat 3. The design of the second cover plate 407 covers the connection between the transfer chamber 303 and the outside, preventing debris generated by the drill bit 404 from scattering outside the placement seat 3 through the transfer chamber 303 and affecting subsequent cleaning.
