Description

Technical Field

[0001] This invention relates to the field of butterfly valve processing technology, and more specifically to a cutting device for the blank structure of the water inlets at both ends of a butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve whose closing element is a disc that rotates around the valve shaft to achieve opening and closing.

[0003] Patent CN118455643A discloses a cutting device for the blank structure of the connecting nozzles at both ends of a butterfly valve, belonging to the field of butterfly valve cutting and processing technology. It includes a mounting frame, with a CNC cutting module at the top. A first support frame and a second support frame are symmetrically mounted within the mounting frame. A tilting table is fixedly connected between the first and second support frames via a second connecting rod and a connecting seat. A movable tray is fixedly connected between the first and second support frames via a first connecting rod. This invention, by incorporating a tilting table, clamping components, and a first servo motor, enables the butterfly valve blank structure cutting device to quickly and stably install and fix the butterfly valve body to be processed. Furthermore, after completing the cutting of one connecting nozzle, the tilting table can be directly tilted to switch to the next connecting nozzle being processed, reducing the workload of workers while improving the efficiency of processing connecting nozzle blanks, resulting in a higher degree of automation.

[0004] The above solution uses a flip-up machining table for double-sided machining. However, the flip-up table may vibrate or shift during the flipping process, affecting the cutting accuracy and failing to ensure the synchronization of machining on both sides. Moreover, the flip-up table lacks rigidity, which may cause the workpiece to shake during machining, affecting the machining quality. Although the device improves the machining efficiency of a single workpiece, if frequent workpiece changes or parameter adjustments are required, it may affect the overall production efficiency. The degree of automation still needs to be improved. Therefore, we propose a cutting device for a butterfly valve billet structure with water outlets at both ends. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cutting device for the blank structure of the butterfly valve connecting the water inlet at both ends involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-9This invention provides a cutting device for a butterfly valve end-connected water inlet blank structure, including a housing 1, a sandwich layer 101 at the bottom of the housing 1, robotic arms 6 on both sides of the housing 1, a first turntable 2 and a support frame 9 rotatably mounted on the lower inner wall of the housing 1, a shifting frame 3 fixedly connected to both sides of the first turntable 2, a feeding mechanism 4 on the upper side of each of the two shifting frames 3, a processing table 7 fixedly connected to the upper inner wall of the housing 1 via a lower suspended support arm 701, an industrial camera 16 mounted on the upper side of the processing table 7, a fixing mechanism 8 installed on both sides of the processing table 7 to fix the blank, and horizontal frames 10 on both the upper and lower sides of the processing table 7, with the two horizontal frames 10 close to the processing table. A tool holder 1001 is rotatably installed at 7 locations, and a tool 1002 is installed on each of the two tool holders 1001. A synchronous drive mechanism 11 and a synchronous lifting mechanism 12 are installed on the support frame 9. The synchronous drive mechanism 11 is used to drive the two tools 1002 to process synchronously. The synchronous lifting mechanism 12 is used to control the two horizontal frames 10 to move synchronously in opposite directions, thereby adjusting the distance between them and the blank. An intermittent switching mechanism 5 and a rotary mechanism 13 are installed in the intermittent switching mechanism 5. The intermittent switching mechanism 5 drives the two sets of feeding mechanisms 4 to rotate intermittently to the lower side of the processing table 7 to assist in feeding and unloading. The rotary mechanism 13 controls the synchronous lifting mechanism 12 to rotate as a whole to adjust the position of the horizontal frame 10.

[0031] In this embodiment, it should be specifically noted that: two sets of feeding mechanisms 4 are symmetrically arranged on both sides of the first turntable 2; two robotic arms 6 are positioned close to the two sets of feeding mechanisms 4; an intermittent switching mechanism 5 is located on the lower side of the first turntable 2 to control the intermittent rotation of the first turntable 2; two lower suspension support arms 701 are provided and fixed at both ends of the processing table 7, with their upper ends fixed to the upper inner wall of the outer shell 1; the processing table 7 and the lower suspension support arms 701 are rigidly connected as a whole, ensuring high stability and preventing shaking, so that each set of feeding mechanisms 4 moves from its initial position to the lower side of the processing table 7; the two sets of feeding mechanisms 4 respectively have clamping, lifting, and rotating functions. During operation, the first robotic arm 6 places the billet onto the first feeding mechanism 4, which holds the billet in place. Then, driven by the intermittent switching mechanism 5, the first turntable 2 rotates 90 degrees, moving the first feeding mechanism 4 to the underside of the processing table 7. The feeding mechanism 4 then lifts the billet, placing it within the processing table 7. The fixing mechanism 8 then secures the billet. The feeding mechanism 4 descends back to its original position and rotates 90 degrees again, switching positions between the first and second feeding mechanisms. The billet is now fixed within the processing table 7, and the entire process is automated, including feeding and unloading. To reduce manual operation time and achieve continuous production, the next step involves adjusting the height of the two horizontal frames 10 via the synchronous lifting mechanism 12. This adjusts the distance between the cutting tool 1002 and the workpiece, ensuring consistent cutting depth and precise control. This keeps the cutting tools 1002 at both ends symmetrically positioned, avoiding machining errors caused by asynchronous movement. The synchronous drive mechanism 11 drives the two cutting tools 1002 to process synchronously, ensuring synchronized movement during cutting and improving machining accuracy and consistency. After processing, the second loading mechanism 4 moves to the loading position under the drive of the intermittent shifting mechanism 5. On the underside of the workbench 7, the processed blank is taken out and returned to the initial position. At this time, another robot arm 6 takes out the processed blank, while the first robot arm 6 puts the blank back on the first set of feeding mechanisms 4. The above operation is repeated. By utilizing the combined action of the feeding mechanism 4 and the intermittent switching mechanism 5, the two sets of feeding mechanisms 4 realize the feeding and unloading functions respectively. The corresponding robot arm 6 cooperates with the feeding and unloading to accurately place the blank in the processing table 7. The positional accuracy of the blank is guaranteed, realizing the automated feeding, unloading and position switching of the blank, ensuring the continuity and efficiency of the processing process, and effectively improving the overall production efficiency.

[0032] The main difference between this embodiment and the prior art is that this embodiment uses continuous automated synchronous processing of both ends of the blank. Specifically, the synchronous drive mechanism 11 and the synchronous lifting mechanism 12 work together. The synchronous drive mechanism 11 ensures that the two ends of the cutting tool 1002 rotate synchronously during the processing, avoiding processing errors caused by asynchronous cutting. The synchronous lifting mechanism 12 adjusts the distance between the cutting tool 1002 and the blank by controlling the reverse synchronous movement of the horizontal frame 10, thereby achieving precise control of the cutting depth. The cooperation of the two ensures the synchronous movement and stability of the cutting tool 1002 during the cutting process, reduces vibration, and improves the surface finish and dimensional accuracy of the processed surface. Through the cooperation of the synchronous drive mechanism 11 and the synchronous lifting mechanism 12, the device can adapt to the processing needs of butterfly valve blanks of different sizes and shapes, and has a wider range of applications. Processing both ends of the blank does not require flipping, ensuring stable processing quality. Moreover, for processing a single type of blank, only fixed equipment parameters need to be adjusted to continuously process the corresponding blank, reducing the impact of large-scale production on production efficiency. Preferably, an industrial camera 16 is installed on the upper inner wall of the outer casing 1. Through visual recognition technology, it can accurately measure the height and position of the blank, ensuring that the blank is accurately fixed on the processing table 7, avoiding processing errors caused by blank placement deviations, and improving processing accuracy and consistency. At the same time, the industrial camera 16 can monitor the position of the blank in real time and feed the data back to the PLC control system, automatically adjusting the actions of the feeding mechanism 4 and the fixing mechanism 8 to ensure the alignment of the blank with the cutting tool 1002, reducing manual intervention, improving automation and production efficiency. Moreover, the industrial camera can monitor the position and status of the blank in real time during the processing, promptly detect abnormalities, ensure the stability of the processing process, reduce the scrap rate, and record the position and size data of the blank in each processing, providing a basis for subsequent process optimization. Through data analysis, processing parameters can be optimized to further improve production efficiency and product quality.

[0033] The above structure is the main structure of this embodiment, which solves the problem of double-sided processing of blanks. The robot arm 6 is an existing structure. The specific structure and connection method of how the tool holder 1001 is processed are not described in detail in this embodiment. In addition, the industrial camera 16 is also existing technology. Therefore, this application does not make detailed limitations.

[0034] Reference Figure 3 and Figure 7The synchronous drive mechanism 11 includes a linkage rod 1101, a fourth motor 1102, two limit seats 1103, and two sets of synchronous components. The linkage rod 1101 is rotatably connected between the upper and lower inner walls of the support frame 9. The fourth motor 1102 is fixedly connected to the top of the support frame 9, and the output end of the fourth motor 1102 is fixedly connected to the linkage rod 1101. The two limit seats 1103 are respectively fixedly connected to opposite sides of the two horizontal frames 10. The linkage rod 1101 passes through the two limit seats 1103. The two sets of synchronous components are located at the two... On the opposite side of the horizontal frame 10, a synchronization assembly is used to link the two cutting tools 1002 for synchronous processing; each synchronization assembly includes a moving synchronous wheel 1104, a stationary synchronous wheel 1105, and a synchronous belt 1106. The moving synchronous wheel 1104 is rotatably connected between the limit seat 1103 and the horizontal frame 10, and the moving synchronous wheel 1104 is slidably connected to the surface of the linkage rod 1101. The stationary synchronous wheel 1105 is fixedly connected to the upper end of the tool holder 1001, and the synchronous belt 1106 is driven between the moving synchronous wheel 1104 and the stationary synchronous wheel 1105.

[0035] In this embodiment, it should be specifically noted that: In this solution, the linkage rod 1101 is rotatably connected between the upper and lower inner walls of the support frame 9, serving as the core transmission component for synchronous movement. The fourth motor 1102 is fixedly connected to the top of the support frame 9 to drive the linkage rod 1101 to rotate. The limiting seat 1103 is fixedly connected to one side of the horizontal frame 10 to limit the range of motion of the linkage rod 1101 and prevent damage to the mechanism due to excessive rotation. The synchronization component is used to transmit the rotational motion of the linkage rod 1101 to the cutting tool 1002. The synchronous drive mechanism 11 drives the two cutting tools 1002 to process synchronously, ensuring that they always maintain synchronous movement during the cutting process, thereby improving machining accuracy and consistency. It has the following functions: Synchronous cutting: Through the linkage 1101 and the synchronization component, the two tools 1002 are ensured to rotate synchronously during the machining process, avoiding machining errors caused by asynchronous cutting; Improve machining accuracy: Synchronous motion ensures that the cutting depth and speed of the two-end tool 1002 are consistent, improving the surface finish and dimensional accuracy of the machined surface; Enhanced machining stability: The rigid design of the synchronous drive mechanism 11 reduces vibration during the cutting process, ensuring the stability of the machining process; The structure is simple and reliable. The synchronous drive mechanism 11 has a compact structure, occupies little space, and is suitable for integration into the device.

[0036] During operation, the fourth motor 1102 is started first, driving the linkage rod 1101 to rotate. Then, the linkage rod 1101 transmits the rotational motion to the stationary synchronization wheel 1105 through the moving synchronous wheel 1104 and the synchronous belt 1106. The stationary synchronization wheel 1105 drives the tool 1002 to rotate, realizing synchronous cutting of the tools at both ends.

[0037] Reference Figure 3 , Figure 7 and Figure 8 The synchronous lifting mechanism 12 includes a fifth motor 1201, a double-threaded lead screw 1202, a lead screw sleeve 1203, and a straight rod 1204. The fifth motor 1201 is fixedly connected to the top of the support frame 9. The double-threaded lead screw 1202 is rotatably connected between the upper and lower inner walls of the support frame 9. The output end of the fifth motor 1201 is fixedly connected to the double-threaded lead screw 1202. Two lead screw sleeves 1203 are provided and are respectively fixedly connected to one end of the two horizontal frames 10 near the double-threaded lead screw 1202. The two lead screw sleeves 1203 are respectively threaded to different threads of the double-threaded lead screw 1202. The straight rod 1204 is fixedly connected between the upper and lower inner walls of the support frame 9. The lead screw sleeve 1203 is slidably connected to the surface of the straight rod 1204.

[0038] In this embodiment, it should be specifically explained that: the fifth motor 1201 provides power to drive the double-threaded lead screw 1202 to rotate. The double-threaded lead screw 1202 has two opposite threads, which mesh with two lead screw sleeves 1203 respectively, realizing the reverse synchronous movement of the horizontal frame 10. The lead screw sleeve 1203 is fixedly connected to one end of the horizontal frame 10 near the double-threaded lead screw 1202 and moves with the rotation of the double-threaded lead screw 1202. The straight rod 1204 is fixedly connected between the upper and lower inner walls of the support frame 9, serving as a guide structure for the lead screw sleeve 1203 to ensure the stability of the movement of the horizontal frame 10. In this scheme, the function of the synchronous lifting mechanism 12 is to control the reverse synchronous movement of the two horizontal frames 10, thereby adjusting the distance between the tool 1002 and the blank to ensure the consistency of the cutting depth. The following is a detailed description of the specific function of the synchronous lifting mechanism 12: Cutting depth adjustment: By controlling the movement of the horizontal frame 10, the distance between the tool 1002 and the workpiece is adjusted to achieve precise control of the cutting depth; Synchronous motion ensures machining accuracy: It ensures that the two horizontal supports 10 move synchronously in opposite directions, so that the tools 1002 at both ends always maintain a symmetrical position, avoiding machining errors caused by asynchronous motion; Adaptable to different sized blanks: By adjusting the position of the horizontal frame 10, it can adapt to butterfly valve blanks of different sizes, thus expanding the processing range of the device.

[0039] When it is necessary to adjust the distance between the tool 1002 and the workpiece, the fifth motor 1201 is started to drive the double threaded screw 1202 to rotate. Since the double threaded screw 1202 has two opposite threads, the two screw sleeves 1203 will move in opposite directions. The screw sleeves 1203 drive the horizontal frame 10 to slide along the straight rod 1204, realizing the opposite synchronous movement of the two horizontal frames 10. The movement of the horizontal frame 10 adjusts the distance between the tool 1002 and the workpiece, thereby controlling the cutting depth.

[0040] Reference Figure 9 The rotary mechanism 13 includes a sixth motor 1301, a worm gear 1302, a fourth turntable 1303, and a worm wheel 1304. The sixth motor 1301 is fixedly connected to the interlayer 101, the worm gear 1302 is fixedly connected to the output end of the sixth motor 1301, the fourth turntable 1303 is rotatably connected to the lower inner wall of the outer shell 1, the support frame 9 is fixedly connected to the top of the fourth turntable 1303, and the worm wheel 1304 is fixedly connected to the lower end of the shaft of the fourth turntable 1303. The worm wheel 1304 is threadedly connected to the worm gear 1302.

[0041] In this embodiment, it should be specifically explained that: the sixth motor 1301 provides power to drive the worm gear 1302 to rotate. The worm gear 1302 meshes with the worm wheel 1304, converting the rotational motion of the sixth motor 1301 into the rotational motion of the support frame 9. The fourth turntable 1303 is fixedly connected to the bottom of the support frame 9 and rotates with the worm wheel 1304, causing the support frame 9 to rotate as a whole. The worm wheel 1304 meshes with the worm gear 1302, transmitting the rotational motion to the fourth turntable 1303. In this solution, the function of the rotary mechanism 13 is to adjust the overall angle of the support frame 9, thereby changing the relative position between the tool 1002 and the workpiece to adapt to different processing requirements. The following is a detailed description of the specific function of the rotary mechanism 13: Multi-angle machining support: By adjusting the angle of the support frame 9, the tool 1002 can cut the blank from different directions to meet complex machining needs; Fine-tuning of processing position: When there is a deviation in the size or shape of the blank, the angle of the support frame 9 can be finely adjusted by the rotary mechanism 13 to ensure that the tool is aligned with the processing area of ​​the blank; Improved processing flexibility: The angle adjustment of support frame 9 expands the processing range of the device, enabling it to adapt to various types of butterfly valve blank processing tasks; When the angle of the support frame 9 needs to be adjusted, the sixth motor 1301 is started to drive the worm gear 1302 to rotate. The worm gear 1302 meshes with the worm wheel 1304, driving the worm wheel 1304 to rotate. The worm wheel 1304 transmits the rotational motion to the support frame 9 through the fourth turntable 1303, causing the support frame 9 to rotate around its axis and adjust the relative position between the tool 1002 and the blank. Moreover, when the horizontal frame 10 may block the movement path of the feeding mechanism 4, the overall angle of the horizontal frame 10 can be adjusted by the rotary mechanism 13 to avoid the feeding mechanism 4 from colliding with the horizontal frame 10.

[0042] Reference Figure 6 Each set of fixing mechanisms 8 includes a cylinder 801 and a clamp 802. The cylinder 801 is fixedly connected to the side of the processing table 7, and the clamp 802 is located inside the processing table 7 and is fixedly connected to the extended end of the cylinder 801.

[0043] In this embodiment, it should be specifically explained that: cylinder 801 is used to provide clamping power, and fixture 802 is located inside the machining table 7 and fixedly connected to the extended end of cylinder 801 for clamping the blank. In this solution, the function of fixing mechanism 8 is to clamp the blank during the machining process, ensuring that the blank remains stable during cutting and avoiding machining errors caused by vibration or displacement. The following is a detailed explanation of the specific function of fixing mechanism 8: Blank fixing: After the blank is transferred to the processing table 7, the fixing mechanism 8 clamps the two ends of the blank to ensure that the blank does not shake during the processing; Improve machining accuracy: By stabilizing the clamping of the workpiece, vibration and offset during the cutting process are reduced, thereby improving the surface finish and dimensional accuracy of the machined surface; Adaptable to different sized blanks: The clamp 802 of the fixing mechanism 8 can adjust the clamping range according to the blank size to adapt to the processing needs of blanks of different specifications; Automated operation: The fixing mechanism 8 works in conjunction with the feeding mechanism 4 and the processing table 7 to achieve automated fixing of the billet and reduce manual intervention; During operation, the blank is transferred to the processing table 7 by the feeding mechanism 4. The two ends of the blank are located between the clamps 802. At this time, the cylinder 801 is activated to drive the clamps 802 to move towards the blank and clamp the two ends of the blank. After the blank is fixed, the tool 1002 cuts the blank. The fixing mechanism 8 ensures that the blank does not shake during the processing. After the processing is completed, the cylinder 801 retracts, the clamps 802 release the blank, and the feeding mechanism 4 removes the finished product from the processing table 7.

[0044] Reference Figure 4 and Figure 5 Each feeding mechanism 4 includes a second turntable 401, a first motor 402, a transfer frame 403, several electric telescopic rods 404, a positioning plate 407, and a clamping assembly. The second turntable 401 is rotatably connected to the upper side of the transfer frame 3. The first motor 402 is fixedly connected to the bottom of the transfer frame 3, and the output end of the first motor 402 is fixedly connected to the second turntable 401. The transfer frame 403 is located on the upper side of the second turntable 401. Several electric telescopic rods 404 are fixedly connected between the transfer frame 403 and the second turntable 401. The positioning plate 407 is fitted and installed on the top of the transfer frame 403. The clamping assembly is disposed on the transfer frame 403. Above; each clamping assembly includes a second motor 405, a third turntable 406, and several grippers 408. An electric telescopic rod 404 is fixedly connected to the bottom of the transfer frame 403. The third turntable 406 is rotatably connected inside the transfer frame 403. The output end of the second motor 405 is fixedly connected to the third turntable 406. Several first sliding grooves 4061 are opened on the upper side of the third turntable 406. Several second sliding grooves 4071 are opened on the upper side of the positioning plate 407. The first sliding grooves 4061 and the second sliding grooves 4071 correspond one-to-one. Several grippers 408 are slidably connected in the corresponding first sliding grooves 4061 and second sliding grooves 4071 respectively.

[0045] In this embodiment, it should be specifically explained that: the second turntable 401 is used to support the transfer frame 403, the first motor 402 is used to drive the second turntable 401 to rotate, the transfer frame 403 is located on the upper side of the second turntable 401 and is used to place the blank, and the electric telescopic rod 404 is used to push the transfer frame 403 to move up and down. In this solution, the function of the feeding mechanism 4 is to realize the gripping, transfer and fixing of the blank, ensuring that the blank can be accurately and stably transferred from the initial position to the processing table 7, providing support for subsequent processing. The following is a detailed explanation of the specific function of the feeding mechanism 4: Billet gripping: The billet is gripped by the clamping assembly to ensure that the billet does not shake during the transfer process; Blank transfer: The blank is transferred from its initial position to the machining table 7 to prepare it for machining; Blank fixing: Inside the processing table 7, the blank is loosened and clamped by the fixing mechanism 8 to ensure stability during the processing; Automated feeding: In conjunction with the intermittent shifting mechanism 5, it realizes automated feeding of billets, reduces manual operation, and improves production efficiency; During operation, the second motor 405 in the clamping assembly is activated, driving the third turntable 406 to rotate. This causes the gripper 408 to slide along the first slide groove 4061 and the second slide groove 4071. The gripper 408 expands outward synchronously to clamp the blank. Then, driven by the intermittent shifting mechanism 5, the positioning plate 407 moves to the underside of the tool 1002. The electric telescopic rod 404 is activated, pushing the transfer frame 403 towards the processing table 7. Simultaneously, the first motor 402 drives the second turntable 401 to rotate, adjusting the angle of the transfer frame 403 to ensure the blank is aligned with the processing table 7. When the blank is transferred into the processing table 7, the fixing mechanisms 8 on both sides of the processing table 7 are activated. The cylinder 801 drives the clamp 802 to clamp both ends of the blank, ensuring stability during processing. After the blank transfer is completed, the electric telescopic rod 404 retracts, and the transfer frame 403 returns to its initial position, ready for the next loading.

[0046] Reference Figure 4 The intermittent shifting mechanism 5 includes a third motor 501, a dial 502, a support shaft 503, and a grooved wheel 504. The third motor 501 is fixedly connected to the interlayer 101, the dial 502 is fixedly connected to the output end of the third motor 501, the support shaft 503 is rotatably connected between the upper and lower inner walls of the interlayer 101, the upper end of the support shaft 503 is fixedly connected to the first turntable 2, and the grooved wheel 504 is fixedly connected to the circumferential surface of the support shaft 503. The dial 502 meshes with the grooved wheel 504.

[0047] In this embodiment, it should be specifically explained that: the third motor 501 provides power, the dial 502 rotates, and the grooved wheel 504 meshes with the dial 502, converting the continuous rotation of the dial 502 into intermittent rotation, which is transmitted to the feeding mechanism 4 through the support shaft 503. In this scheme, the function of the intermittent switching mechanism 5 is to drive the feeding mechanism 4 to rotate intermittently, moving the blank from the initial position to the lower side of the processing table 7, assisting in completing the blank feeding and unloading process. The following is a detailed description of the specific function of the intermittent switching mechanism 5: Blank loading: By intermittently rotating, the loading mechanism 4 is moved from the initial position to the lower side of the processing table 7 to complete the loading of the blank; Blank unloading: After processing is completed, the feeding mechanism 4 is moved back to the initial position to complete the unloading of the finished product; Position switching: By intermittently rotating, the feeding mechanism 4 switches between the initial position and the lower side of the processing table 7 to ensure that there is always blank available for processing on the processing table 7; Improve production efficiency: Reduce manual operation time and achieve continuous production through automated feeding and unloading; When loading or unloading is required, the third motor 501 is started to drive the dial 502 to rotate. The dial 502 meshes with the grooved wheel 504, causing the grooved wheel 504 to rotate intermittently. The grooved wheel 504 drives the first turntable 2 and the loading mechanism 4 to rotate intermittently through the support shaft 503, so that the loading mechanism 4 moves from the initial position to the lower side of the processing table 7, and then the loading of the blank is completed. After loading, it continues to rotate intermittently to avoid obstructing the tool 1002. After processing is completed, the loading mechanism 4 rotates intermittently again, and another loading mechanism 4 moves to the lower side of the processing table 7 to complete the unloading of the finished product.

[0048] Reference Figure 4 The top of the outer casing 1 is equipped with a water inlet pipe 15, and the upper side of the processing table 7 is provided with a nozzle 1501, which is installed at the end of the water inlet pipe 15.

[0049] In this embodiment, it should be specifically explained that the function of the water inlet pipe 15 is to provide coolant for the machining process. During the cutting process, the cutting tool 1002 and the blank generate high temperature due to friction. The water inlet pipe 15 sprays coolant through the nozzle 1501 to reduce the temperature, prevent the cutting tool from overheating and the blank from deforming, and ensure that the temperature of the cutting tool 1002 and the blank is effectively controlled during the cutting process, thereby improving the machining quality and tool life.

[0050] Preferred options, please refer to Figure 2 and Figure 7 A static limit block 1401 is fixedly installed on the lower inner wall of the outer shell 1, and a dynamic limit block 14 is fixedly installed on the bottom of the support frame 9. This can limit the rotation range of the support frame 9, ensure that the support frame 9 will not rotate excessively, and improve safety.

[0051] Working principle of the invention: The main problem solved by this embodiment is that by using the synchronous drive mechanism 11 and the synchronous lifting mechanism 12 in combination, the cutting tools 1002 at both ends are ensured to rotate synchronously during the processing, avoiding processing errors caused by asynchronous cutting, ensuring the synchronous movement and stability of the cutting tools 1002 during the cutting process, solving the processing accuracy problem caused by flipping processing, improving the surface finish and dimensional accuracy of the processed surface, and by using the loading mechanism 4 and the intermittent shifting mechanism 5 in combination, the automatic loading and unloading of the blank is realized, the positional fixation accuracy of the blank is guaranteed, and the problem of loading and unloading offset caused by flipping processing is solved.

[0052] The specific steps are as follows: S1. Check the integrity of the equipment: Confirm that the outer shell 1, support frame 9, processing table 7, feeding mechanism 4 and other structures are free from deformation or looseness. Check the wear of vulnerable parts such as cutting tool 1002 and clamp 802, and replace them if necessary. Connect the water inlet pipe 15 and check whether the spray nozzle 1501 is unobstructed to ensure that the coolant spray covers the cutting tool processing area. S2. Blank clamping and positioning: Place the blank on the transfer frame 403 of the first feeding mechanism 4, ensuring good contact between the blank and the positioning plate 407. Start the second motor 405 in the clamping assembly to drive the third turntable 406 to rotate, so that the gripper 408 slides along the first slide groove 4061 and the second slide groove 4071 to clamp the blank. Then, drive the second turntable 401 to rotate through the first motor 402 to fine-tune the position of the blank.

[0053] S3. Blank Transfer: Start the third motor 501 in the intermittent switching mechanism 5 to drive the dial 502 to rotate, which in turn drives the grooved wheel 504 to rotate intermittently, moving the first set of feeding mechanisms 4 to the lower side of the processing table 7. The electric telescopic rod 404 of the first set of feeding mechanisms 4 pushes the transfer frame 403 to transfer the blank from the transfer frame 403 to the processing table 7. At this time, the fixing mechanisms 8 on both sides of the processing table 7 are activated, and the cylinder 801 drives the clamp 802 to clamp the two ends of the blank, ensuring that the blank does not shake during the processing. Then the first set of feeding mechanisms 4 rotates intermittently again to switch positions with the second set of feeding mechanisms 4.

[0054] S4. Machining parameter setting: The speed of the fourth motor 1102 is set by the PLC, and the linkage rod 1101 drives the synchronous pulley 1104 and the synchronous belt 1106 to ensure that the speed of the two tools 1002 is the same; Start the fifth motor 1201 to drive the double threaded screw 1202 to rotate, causing the screw sleeve 1203 to drive the horizontal frame 10 to move in the opposite direction, adjusting the distance between the tool and the blank to the preset value; S5. Process execution: Select the processing program on the PLC control interface, start the synchronous drive mechanism 11, the tool 1002 rotates at high speed and synchronously cuts the water inlets at both ends of the blank, and the nozzle 1501 continuously sprays coolant to reduce the tool temperature and wash away the chips, ensuring the surface finish of the machined surface, and observe the vibration of the processing table 7 in real time through 16. S6. Finished Product Unloading: After completing the single-piece processing, the third motor 501 drives the dial 502 to rotate again, causing the grooved wheel 504 to rotate intermittently, moving the second set of loading mechanisms 4 to the lower side of the processing table 7. The finished product after the blank processing is taken out by the second set of loading mechanisms 4, and then it moves intermittently again to switch the initial position of the second set of loading mechanisms 4 with the first set of loading mechanisms 4. At this time, the robot arm 6 grabs the finished product on the second set of loading mechanisms 4 and moves it to the unloading area, and the first set of loading mechanisms 4 returns to the initial position. S7. New billet loading: Place the new billet on the transfer frame 403 of the first loading mechanism 4, and repeat steps 2 to 6 to achieve continuous production.
