Description

Technical Field

[0001] The present invention relates to the technical field of spinneret processing, specifically an automated control system for processing special-shaped holes of spinnerets. Background Art

[0002] During the processing of special-shaped holes of spinnerets, debris will be generated. These debris adhere to the tool or the inner wall of the hole, which will increase the frictional resistance between the tool and the inner wall of the hole, resulting in accelerated tool wear. Moreover, the accumulation of debris on the inner wall of the hole will affect the stability of the tool movement, affect the roughness of the inner wall of the hole, and further affect the processing accuracy. If the debris accumulates excessively, it will cause blockage of the drilling position, resulting in interruption of processing. If the drilling position is frequently blocked by debris, manual shutdown is required to clean the debris, which will affect the continuous operation of the automated production line and thus affect the processing efficiency.

[0003] In traditional machining centers, the coolant is often ejected in a direct injection manner. The flow rate of the direct injection coolant is low, and it is difficult to effectively remove the fine debris in the micro-holes. Moreover, in traditional direct injection cooling, the spray pipe is often fixed beside the main shaft and flushes the processing hole at a fixed angle. In the processing of special-shaped holes of spinnerets, debris is likely to remain at the corners or narrow areas of the special-shaped holes. The fixed-angle spray pipe has a flushing dead angle and is not easy to flush out the debris, which is likely to cause debris to accumulate in the special-shaped holes. In addition, the coolant impacts the hole wall vertically, which is likely to cause scratches or slight cracks on the hole wall, affecting the processing accuracy. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated control system for processing special-shaped holes of spinnerets to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The present invention provides a technical solution for an automated control system for processing special-shaped holes of spinnerets. The automated control system for processing special-shaped holes of spinnerets includes a machine body, a conveying mechanism, a robotic arm, a workbench, a positioning mechanism, a processing mechanism, a cooling mechanism, a moving mechanism, and a controller. There are two conveying mechanisms. The machine body is fixedly connected to the two conveying mechanisms. The robotic arm is fixedly connected to the machine body. The moving mechanism is fixedly connected to the machine body. The moving mechanism is fixedly connected to the workbench. The workbench is fixedly connected to the positioning mechanism. The processing mechanism is fixedly connected to the machine body. The cooling mechanism is fixedly connected to the processing mechanism. The cooling mechanism is fixedly connected to the machine body. The controller is fixedly connected to the machine body. The robotic arm is electrically connected to the controller. The positioning mechanism is electrically connected to the controller. The processing mechanism is electrically connected to the controller. The cooling mechanism is electrically connected to the controller. The moving mechanism is electrically connected to the controller.

[0007] With the provided body as a support platform, it is used to install modules such as a conveying mechanism, a robotic arm, a processing mechanism, a cooling mechanism, a moving mechanism, and a controller. Through the provided two conveying mechanisms, which are distributed at both ends of the workbench and used to convey spinnerets. Through the robotic arm, the grasping mechanism at the end of the robotic arm transfers the spinneret to be processed on the conveying mechanism to the positioning mechanism on the workbench. The positioning mechanism is electrically connected to the controller, enabling the controller to control the positioning mechanism to position and clamp the spinneret to be processed. The processing mechanism is electrically connected to the controller, enabling the controller to control the processing mechanism to process the spinneret to be processed. The moving mechanism is electrically connected to the controller, and the controller controls the moving mechanism to drive the workbench to move along a specific trajectory, enabling the positioning mechanism and the spinneret to be processed to move, thereby realizing the processing of special-shaped holes. At the same time, the cooling mechanism is electrically connected to the controller, enabling the controller to control the cooling mechanism to cool the spinneret during processing. At the same time, the controller controls the cooling mechanism to dynamically adjust the flushing angle to avoid dead zones of flushing and prevent debris from remaining in the corners or narrow areas of the special-shaped holes. After processing is completed, the controller controls the positioning mechanism to release the spinneret, the controller controls the robotic arm to move the spinneret to another conveying mechanism for conveyance away, the controller controls the processing mechanism to process the spinneret on another positioning mechanism, and the controller controls the robotic arm to move the spinneret to be processed on the conveying mechanism to the positioning mechanism again, thereby realizing continuous processing. The controller controls the automatic processing of the special-shaped holes of the spinneret, thus realizing the automation of the processing of the special-shaped holes of the spinneret.

[0008] Further, the cooling mechanism includes a water pump, a cooling spray pipe, a filter, a water tank, a first mounting frame, a first adjustment unit, and a connection unit. The water pump is connected to the processing mechanism through a pipeline. The workbench is provided with a collection groove and a through hole. The through hole is communicated with the collection groove. The filter is connected to the collection groove through a pipeline. The water tank is connected to the filter through a pipeline. The water tank is connected to the water pump through a pipeline. The first mounting frame is fixedly connected to the cooling spray pipe. The first mounting frame is fixedly connected to the first adjustment unit. The first adjustment unit is rotationally connected to the processing mechanism. The connection unit is rotationally connected to the processing mechanism. The connection unit is fixedly connected to the cooling spray pipe.

[0009] The water pump is connected to the processing mechanism through a pipeline, so that the coolant in the water tank is transported to the processing mechanism by the water pump. Subsequently, the coolant enters the connection unit, and the coolant is transported to the cooling nozzle through the connection unit. The coolant is ejected through the cooling nozzle, thereby cooling the special-shaped holes during the processing of the spinneret. The first adjustment unit adjusts the first mounting bracket according to the trajectory of the special-shaped hole processing, so that the first mounting bracket rotates along the tool of the processing mechanism. Since the first mounting bracket is fixed to the cooling nozzle, the first mounting bracket drives the cooling nozzle to rotate together, and at the same time the connection unit also rotates accordingly to ensure the connection between the cooling nozzle and the connection unit, thereby changing the scouring angle of the coolant ejected by the cooling nozzle on the special-shaped hole. The used coolant flows into the collection tank through the through hole provided on the workbench, and the coolant in the collection tank flows into the filter through a pipeline. After the filter filters the debris in the coolant, it flows back into the water tank, realizing the recycling of the coolant, thereby reducing the production cost.

[0010] Further, the cooling nozzle includes an acceleration tube, a nozzle, and a guide vane. The acceleration tube is communicated with the nozzle. The acceleration tube is provided with a contraction section and an expansion section. The expansion section is communicated with the nozzle. The guide vane is fixedly connected to the inner wall of the nozzle.

[0011] The coolant in the water tank is transported to the cooling nozzle by the water pump. The coolant first enters the acceleration tube. Through the contraction section provided in the acceleration tube, the liquid passage becomes narrower, thereby accelerating the coolant. The pressure is restored through the subsequent expansion section, so that the coolant is ejected from the nozzle at a high speed, thereby increasing the scouring force on the debris inside the special-shaped hole. Through the guide vane provided near the outlet on the inner wall of the nozzle, the guide vane is spiral, so that the ejected coolant generates a swirl, thereby enhancing the scouring effect on the inner wall of the special-shaped hole and generating a centrifugal force. The debris inside the special-shaped hole is thrown out by the centrifugal force to prevent the debris from remaining inside the special-shaped hole.

[0012] Further, the first adjustment unit includes a second mounting bracket, a first motor, a first gear, and a second gear. The second mounting bracket is fixedly connected to the processing mechanism. The first motor is fixedly connected to the second mounting bracket. The output end of the first motor is fixedly connected to the first gear. The first gear meshes with the second gear. The second gear is rotatably connected to the processing mechanism.

[0013] Through the second mounting bracket, the first motor is fixed on the processing mechanism. The first motor drives the first gear to rotate, so that the first gear drives the second gear to rotate. The axis of the second gear is collinear with the axis of the tool of the processing mechanism, so that the second gear rotates along the tool. The second gear drives the first mounting bracket fixed to its end face to rotate together, so that the cooling nozzle rotates along the tool, thereby changing the scouring angle of the special-shaped hole being processed.

[0014] Furthermore, the processing mechanism includes a mounting plate, a linear module, a connecting plate, a main shaft, a limiting block, and a second adjusting unit. The mounting plate is fixedly connected to the machine body. The linear module is fixedly connected to the mounting plate. The sliding end of the linear module is fixedly connected to the connecting plate. The connecting plate is provided with a sliding groove. The main shaft is slidably connected to the sliding groove. The main shaft is fixedly connected to the limiting block. The limiting block is slidably connected to the sliding groove. The second adjusting unit is fixedly connected to the main shaft and is disposed within the sliding groove.

[0015] The linear module is vertically mounted through the mounting plate and fixed through the connecting plate and the sliding end of the linear module, enabling the linear module to drive the connecting plate to move up and down, and further driving the main shaft on the connecting plate to move up and down. The controller controls the main shaft to drive the cutter mounted thereon to rotate for processing. Through the robotic arm, different cutters are replaced for the main shaft from the tool magazine during the processing, so as to first drill holes, then mill, and finally finish reaming, thereby realizing the processing of special-shaped holes on the spinneret. When the cutter on the main shaft contacts the spinneret, the main shaft slides into the sliding groove, thereby triggering the second adjusting unit to transmit data to the controller according to the material of the spinneret, enabling the controller to adjust the rotation speed of the main shaft. The limiting block prevents the main shaft from falling.

[0016] Furthermore, the connecting unit includes a connecting block, bearings, and sealing rings. The connecting block is rotatably connected to the connecting plate. There are two bearings. The inner rings of the two bearings are fixedly connected to the connecting block, and the outer rings of the two bearings are fixedly connected to the connecting plate. There are two sealing rings. The two sealing rings are tightly connected to the connecting block, and the two sealing rings are tightly connected to the connecting plate. The connecting plate is provided with an annular groove. The water pump is in pipeline communication with the annular groove. The connecting block is provided with a fluid passage, and the fluid passage is in communication with the annular groove. The fluid passage is in communication with the acceleration tube.

[0017] The inner rings of the two bearings are fixedly connected to the connecting block, and the outer rings of the two bearings are fixedly connected to the connecting plate. The inner ring of the bearing rotates along the outer ring through steel balls, enabling the inner ring of the bearing to drive the connecting block to rotate within the connecting plate. The connecting plate is provided with an annular groove, and the water pump is in pipeline communication with the annular groove, enabling the water pump to deliver the coolant to the annular groove. The fluid passage in the connecting block is in communication with the annular groove, and the fluid passage is in communication with the acceleration tube, enabling the coolant to be delivered to the acceleration tube through the fluid passage. The axes of the connecting block, the annular groove, and the main shaft coincide, such that when the connecting block rotates, the fluid passage and the annular groove are always in communication. There are two sealing rings, and the two sealing rings are respectively located on both sides of the annular groove. The sealing rings are tightly connected to the connecting block and the connecting plate, thereby performing sealing to prevent water leakage.

[0018] Furthermore, the second adjusting unit includes electrodes, piezoelectric ceramic sheets, and conical springs. There are two electrodes. The two electrodes are fixedly connected to the sliding groove, the two electrodes are fixedly connected to the piezoelectric ceramic sheets, the conical springs are fixedly connected to the electrodes, the conical springs are fixedly connected to the main shaft, and the electrodes are electrically connected to the controller.

[0019] When the main shaft is driven by a linear module to move downward, the tool of the main shaft contacts the spinneret. At the same time, the main shaft continues to move downward for processing. When the tool processes the special-shaped hole, the tool needs to move along a set path. There are corners in the special-shaped hole. When the tool moves to the corner, it will turn. The tool transfers from the original path to the new path, so that the tool contacts the materials in two directions at the same time. The contacted materials transmit the force to the main shaft through the spiral structure of the tool, so that the reaction force of the tool on the main shaft will change. Through the provided conical spring, different reaction forces cause the main shaft to slide into the sliding groove by different depths, so that the compression amount of the conical spring is different, thereby generating different pressures on the electrode. Through the fixation of the electrode and the piezoelectric ceramic sheet, the pressure is transmitted to the piezoelectric ceramic sheet, so that the piezoelectric ceramic sheet generates an electric current with different voltages. Through the electrical signal connection between the electrode and the controller, the current is transmitted to the controller. The controller adjusts the rotation speed of the main shaft 64 according to the current with different voltages transmitted, reduces the concentration of thermal stress, and thus ensures the smoothness of the inner wall of the processed hole.

[0020] Further, the positioning mechanism includes a base, a second motor, a bidirectional lead screw, fixed seats, nut seats, clamping plates and a bearing seat. The base is fixedly connected to the workbench. There are two fixed seats, and the two fixed seats are fixedly connected to the base. The bidirectional lead screw is rotatably connected to the two fixed seats. There are two nut seats, and the two nut seats are threadedly connected to the bidirectional lead screw. The second motor is fixedly connected to the fixed seat, and the output end of the second motor is fixedly connected to the bidirectional lead screw. There are two clamping plates, and the two clamping plates are respectively fixedly connected to the two nut seats. The bearing seat is fixedly connected to the base.

[0021] By fixedly connecting the base to the workbench, the base serves as a support structure for installing various components. The two fixed seats support both ends of the bidirectional lead screw. The second motor drives the bidirectional lead screw to rotate, so that the two nut seats on the bidirectional lead screw approach or move away from each other. The two nut seats respectively drive the two clamping plates independently fixed to them to move, so as to realize the clamping or loosening of the spinneret. Through the V-shaped grooves provided on the clamping plates, the circular spinneret can be automatically positioned while being clamped. The provided bearing seat is used to place the spinneret and cool the bottom of the spinneret at the same time.

[0022] Further, the bearing seat is provided with an empty groove, and the bearing seat is provided with a plurality of water outlets, and the empty groove is communicated with the water pump pipeline.

[0023] By providing an empty groove in the bearing seat and communicating the empty groove with the water pump pipeline, the coolant is transported to the empty groove through the water pump. Through the plurality of water outlets provided on the bearing seat, the coolant is sprayed out, so as to cool the bottom of the spinneret. After the processing of the special-shaped holes on the spinneret is completed, the coolant is flushed upward from the bottom of the spinneret, so that the debris at the bottom is washed out of the processed special-shaped holes, avoiding the residue of debris in the holes and the need for secondary cleaning of the spinneret.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The coolant first enters the acceleration tube. Since the acceleration tube is provided with a contraction section, the coolant is accelerated and ejected from the nozzle at a high speed, thereby increasing the scouring force on the debris inside the shaped hole. By providing a guide vane near the outlet on the inner wall of the nozzle, the guide vane is spiral, so that the ejected coolant generates a swirl, thereby enhancing the scouring effect on the inner wall of the shaped hole, avoiding the coolant from vertically impacting the hole wall, thus ensuring the machining accuracy, and generating a centrifugal force. Through the centrifugal force, the debris inside the shaped hole is thrown out, avoiding the debris remaining inside the shaped hole and the accumulation of debris blocking the drilling position, and ensuring the continuity of machining.

[0026] 2. The first motor drives the first gear to drive the second gear to rotate along the tool, so that the cooling spray pipe rotates along the tool, thereby changing the scouring angle of the shaped hole during machining, so as to accurately scour the corner or narrow area of the shaped hole, avoid the occurrence of scouring dead corners, and further avoid the accumulation of debris in the shaped hole.

[0027] 3. The coolant is ejected from the water outlet of the bearing seat, thereby cooling the bottom of the spinneret. After the machining of the shaped holes on the spinneret is completed, the coolant flushes upward from the bottom of the spinneret, so that the debris at the bottom is washed out of the machined shaped holes, avoiding the remaining debris at the bottom of the shaped holes, and further avoiding the need for secondary cleaning of the spinneret.

[0028] 4. When the tool is machining the shaped hole, the tool needs to move along a set path. There are corners in the shaped hole. When the tool moves to the corner, it will turn. The tool transfers from the original path to a new path, so that the tool contacts the materials in two directions at the same time. The contacted materials transfer the force to the spindle through the spiral structure of the tool, so that the reaction force of the tool on the spindle will change, resulting in different compression amounts of the conical spring, thereby generating different pressures on the piezoelectric ceramic sheet, causing the piezoelectric ceramic sheet to generate currents with different voltages. Through the electrode, the current is transmitted to the controller. The controller adjusts the rotation speed of the spindle according to the currents with different voltages transmitted, reduces the concentration of thermal stress, and thus ensures the smoothness of the inner wall of the machined hole.

Specific embodiments

[0040] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment: As Figure 1As shown in the figure, the present invention provides an automatic control system technical solution for processing special-shaped holes of a spinneret. The automatic control system for processing special-shaped holes of a spinneret includes a machine body 1, a conveying mechanism 2, a robotic arm 3, a workbench 4, a positioning mechanism 5, a processing mechanism 6, a cooling mechanism 7, a moving mechanism 8, and a controller 9. There are two conveying mechanisms 2. The machine body 1 is fixedly connected to the two conveying mechanisms 2. The robotic arm 3 is fixedly connected to the machine body 1. The moving mechanism 8 is fixedly connected to the machine body 1. The moving mechanism 8 is fixedly connected to the workbench 4. The workbench 4 is fixedly connected to the positioning mechanism 5. The processing mechanism 6 is fixedly connected to the machine body 1. The cooling mechanism 7 is fixedly connected to the processing mechanism 6. The cooling mechanism 7 is fixedly connected to the machine body 1. The controller 9 is fixedly connected to the machine body 1. The robotic arm 3 is electrically connected to the controller 9. The positioning mechanism 5 is electrically connected to the controller 9. The processing mechanism 6 is electrically connected to the controller 9. The cooling mechanism 7 is electrically connected to the controller 9. The moving mechanism 8 is electrically connected to the controller 9.

[0042] By providing the machine body 1 as a support platform for installing modules such as the conveying mechanism 2, the robotic arm 3, the processing mechanism 6, the cooling mechanism 7, the moving mechanism 8, and the controller 9. By providing two conveying mechanisms 2, the conveying mechanisms 2 are distributed at both ends of the workbench 4 for conveying the spinneret. Through the robotic arm 3, the grasping mechanism at the end of the robotic arm 3 transfers the spinneret to be processed on the conveying mechanism 2 to the positioning mechanism 5 on the workbench 4. Since the positioning mechanism 5 is electrically connected to the controller 9, the controller 9 controls the positioning mechanism 5 to position and clamp the spinneret to be processed. Since the processing mechanism 6 is electrically connected to the controller 9, the controller 9 controls the processing mechanism 6 to process the spinneret to be processed. Since the moving mechanism 8 is electrically connected to the controller 9, the controller 9 controls the moving mechanism 8 to drive the workbench 4 to move along a specific trajectory, so that the positioning mechanism 5 and the spinneret to be processed move, thereby realizing the processing of special-shaped holes. At the same time, since the cooling mechanism 7 is electrically connected to the controller 9, the controller 9 controls the cooling mechanism 7 to cool the spinneret during processing. At the same time, the controller 9 controls the cooling mechanism 7 to dynamically adjust the flushing angle to avoid flushing dead zones and prevent debris from remaining in the corners or narrow areas of the special-shaped holes. After processing is completed, the controller 9 controls the positioning mechanism 5 to release the spinneret, the controller 9 controls the robotic arm 3 to move the spinneret to another conveying mechanism 2 for conveying away, the controller 9 controls the processing mechanism 6 to process the spinneret on another positioning mechanism 5, and the controller 9 controls the robotic arm 3 to move the spinneret to be processed on the conveying mechanism 2 to the positioning mechanism 5 again, thereby realizing continuous processing. The controller 9 controls the automatic processing of the special-shaped holes of the spinneret, thereby realizing the automation of the processing of the special-shaped holes of the spinneret.

[0043] As Figures 1 - 4As shown in the figure, the cooling mechanism 7 includes a water pump 71, a cooling nozzle 72, a filter 73, a water tank 74, a first mounting bracket 75, a first adjusting unit 76 and a connecting unit 77. The water pump 71 is connected to the processing mechanism 6 through a pipeline. The workbench 4 is provided with a collection groove 41 and a through hole 42. The through hole 42 is communicated with the collection groove 41. The filter 73 is communicated with the collection groove 41 through a pipeline. The water tank 74 is communicated with the filter 73 through a pipeline. The water tank 74 is communicated with the water pump 71 through a pipeline. The first mounting bracket 75 is fixedly connected to the cooling nozzle 72. The first mounting bracket 75 is fixedly connected to the first adjusting unit 76. The first adjusting unit 76 is rotatably connected to the processing mechanism 6. The connecting unit 77 is rotatably connected to the processing mechanism 6. The connecting unit 77 is fixedly connected to the cooling nozzle 72.

[0044] By connecting the water pump 71 to the processing mechanism 6 through a pipeline, the coolant in the water tank 74 is transported to the processing mechanism 6 by the water pump 71. Subsequently, the coolant enters the connecting unit 77 and is transported to the cooling nozzle 72 by the connecting unit 77. The coolant is ejected through the cooling nozzle 72 to cool the shaped holes during the processing of the spinneret. The first adjusting unit 76 adjusts the first mounting bracket 75 according to the trajectory of the shaped hole processing, so that the first mounting bracket 75 rotates along the tool of the processing mechanism 6. Since the first mounting bracket 75 is fixed to the cooling nozzle 72, the first mounting bracket 75 drives the cooling nozzle 72 to rotate together, and at the same time the connecting unit 77 also rotates accordingly, ensuring the connection between the cooling nozzle 72 and the connecting unit 77, and then changing the flushing angle of the coolant ejected by the cooling nozzle 72 on the shaped hole. The used coolant flows into the collection groove 41 through the through hole 42 provided on the workbench 4. The coolant in the collection groove 41 flows into the filter 73 through a pipeline. After the filter 73 filters the debris in the coolant, it flows back into the water tank 74 again, realizing the recycling of the coolant and thus reducing the production cost.

[0045] As Figure 5 shown in the figure, the cooling nozzle 72 includes an acceleration tube 721, a nozzle 722 and a guide vane 723. The acceleration tube 721 is communicated with the nozzle 722. The acceleration tube 721 is provided with a contraction section 7211. The acceleration tube 721 is provided with an expansion section 7212. The expansion section 7212 is communicated with the nozzle 722. The guide vane 723 is fixedly connected to the inner wall of the nozzle 722.

[0046] The coolant in the water tank 74 is transported to the cooling nozzle 72 by the water pump 71. The coolant first enters the acceleration pipe 721. The acceleration pipe 721 is provided with a contraction section 7211, which narrows the liquid passage, thereby accelerating the coolant. The pressure is restored through the subsequent expansion section 7212, and the coolant is ejected from the nozzle 722 at a high speed, thereby increasing the scouring force on the debris in the shaped hole. By arranging the guide vane 723 near the outlet on the inner wall of the nozzle 722, the guide vane 723 is spiral, so that the ejected coolant generates a swirl, thereby enhancing the scouring effect on the inner wall of the shaped hole and generating a centrifugal force. The debris in the shaped hole is thrown out by the centrifugal force, preventing the debris from remaining inside the shaped hole.

[0047] As Figure 2 shown, the first adjustment unit 76 includes a second mounting bracket 761, a first motor 762, a first gear 763 and a second gear 764. The second mounting bracket 761 is fixedly connected to the processing mechanism 6. The first motor 762 is fixedly connected to the second mounting bracket 761. The output end of the first motor 762 is fixedly connected to the first gear 763. The first gear 763 meshes with the second gear 764. The second gear 764 is rotatably connected to the processing mechanism 6.

[0048] Through the second mounting bracket 761, the first motor 762 is fixed on the processing mechanism 6. By driving the first gear 763 to rotate through the first motor 762, the first gear 763 drives the second gear 764 to rotate. The axis of the second gear 764 is collinear with the axis of the tool of the processing mechanism 6, so that the second gear 764 rotates along the tool. The second gear 764 drives the first mounting bracket 75 fixed on its end face to rotate together, so that the cooling nozzle 72 rotates along the tool, thereby changing the scouring angle of the shaped hole during processing.

[0049] As Figure 3 and Figure 6 shown, the processing mechanism 6 includes a mounting plate 61, a linear module 62, a connecting plate 63, a main shaft 64, a limit block 65 and a second adjustment unit 66. The mounting plate 61 is fixedly connected to the machine body 1. The linear module 62 is fixedly connected to the mounting plate 61. The sliding end of the linear module 62 is fixedly connected to the connecting plate 63. The connecting plate 63 is provided with a sliding groove 631. The main shaft 64 is slidably connected to the sliding groove 631. The main shaft 64 is fixedly connected to the limit block 65. The limit block 65 is slidably connected to the sliding groove 631. The second adjustment unit 66 is fixedly connected to the main shaft 64. The second adjustment unit 66 is placed in the sliding groove 631.

[0050] The linear module 62 is vertically installed through the mounting plate 61 and fixed to the sliding end of the linear module 62 through the connecting plate 63, enabling the linear module 62 to drive the connecting plate 63 to move up and down. Furthermore, it drives the main shaft 64 on the connecting plate 63 to move up and down. The controller 9 controls the main shaft 64 to drive the cutting tool mounted on it to rotate for machining. Through the robotic arm 3, different cutting tools are replaced for the main shaft 64 from the tool magazine during the machining process, so as to drill first, then mill, and finally finish reaming, thereby realizing the machining of special-shaped holes on the spinneret plate. When the cutting tool of the main shaft 64 contacts the spinneret plate, the main shaft 64 slides into the sliding groove 631, thereby triggering the second adjustment unit 66 to transmit data to the controller 9 according to the material of the spinneret plate, enabling the controller 9 to adjust the rotation speed of the main shaft 64. The limiting block 65 is used to prevent the main shaft 64 from falling off.

[0051] As Figure 7 and Figure 8 shown, the connecting unit 77 includes a connecting block 771, bearings 772, and sealing rings 773. The connecting block 771 is rotatably connected to the connecting plate 63. There are two bearings 772. The inner rings of the two bearings 772 are fixedly connected to the connecting block 771, and the outer rings of the two bearings 772 are fixedly connected to the connecting plate 63. There are two sealing rings 773. The two sealing rings 773 are tightly connected to the connecting block 771, and the two sealing rings 773 are tightly connected to the connecting plate 63. The connecting plate 63 is provided with an annular groove 632. The water pump 71 is in pipeline communication with the annular groove 632. The connecting block 771 is provided with a fluid passage 7711, and the fluid passage 7711 is in communication with the annular groove 632. The fluid passage 7711 is in communication with the acceleration tube 721.

[0052] By fixedly connecting the inner rings of the two bearings 772 to the connecting block 771 and the outer rings of the two bearings 772 to the connecting plate 63, and the inner ring of the bearing 772 rotates along the outer ring through steel balls, the inner ring of the bearing 772 drives the connecting block 771 to rotate within the connecting plate 63. The connecting plate 63 is provided with an annular groove 632, and the water pump 71 is in pipeline communication with the annular groove 632, enabling the water pump 71 to deliver the coolant into the annular groove 632. The fluid passage 7711 in the connecting block 771 is in communication with the annular groove 632, and the fluid passage 7711 is in communication with the acceleration tube 721, enabling the coolant to be delivered to the acceleration tube 721 through the fluid passage 7711. The axes of the connecting block 771, the annular groove 632, and the main shaft 64 coincide, such that when the connecting block 771 rotates, the fluid passage 7711 and the annular groove 632 are always in communication. Since there are two sealing rings 773, and the two sealing rings 773 are respectively located on both sides of the annular groove 632, and the sealing rings 773 are tightly connected to the connecting block 771 and the connecting plate 63, sealing is thus carried out to prevent water leakage.

[0053] As Figure 6As shown in the figure, the second adjusting unit 66 includes an electrode 661, a piezoelectric ceramic sheet 662, and a conical spring 663. There are two electrodes 661. The two electrodes 661 are fixedly connected to the sliding groove 631. The two electrodes 661 are fixedly connected to the piezoelectric ceramic sheet 662. The conical spring 663 is fixedly connected to the electrode 661. The conical spring 663 is fixedly connected to the main shaft 64. The electrode 661 is electrically connected to the controller 9 through an electrical signal.

[0054] When the main shaft 64 is driven by the linear module 62 to move downward, the cutting tool of the main shaft 64 contacts the spinneret. At the same time, the main shaft 64 continues to move downward for processing. When the cutting tool processes the shaped hole, the cutting tool needs to move along a set path. There are corners in the shaped hole. When the cutting tool moves to the corner, it will turn. The cutting tool transfers from the original path to a new path, so that the cutting tool contacts the materials in two directions at the same time. The contacted materials transfer the force to the main shaft 64 through the spiral structure of the cutting tool. As a result, the reaction force of the cutting tool on the main shaft 64 will change. Through the provided conical spring 663, different reaction forces cause the main shaft 64 to slide into the sliding groove 631 to different depths, so that the compression amount of the conical spring 663 is different, thereby generating different pressures on the electrode 661. Since the electrode 661 is fixed to the piezoelectric ceramic sheet 662, the pressure is transferred to the piezoelectric ceramic sheet 662, causing the piezoelectric ceramic sheet 662 to generate an electric current with different voltages. Through the electrical connection between the electrode 661 and the controller 9, the electric current is transmitted to the controller 9. The controller 9 adjusts the rotation speed of the main shaft 64 according to the electric current with different voltages transmitted, reduces the concentration of thermal stress, and thus ensures the smoothness of the inner wall of the processed hole.

[0055] As Figure 4 and Figure 9 As shown in the figure, the positioning mechanism 5 includes a base 51, a second motor 52, a bidirectional lead screw 53, a fixed seat 54, a nut seat 55, a clamping plate 56, and a bearing seat 57. The base 51 is fixedly connected to the workbench 4. There are two fixed seats 54. The two fixed seats 54 are fixedly connected to the base 51. The bidirectional lead screw 53 is rotatably connected to the two fixed seats 54. There are two nut seats 55. The two nut seats 55 are threadedly connected to the bidirectional lead screw 53. The second motor 52 is fixedly connected to the fixed seat 54. The output end of the second motor 52 is fixedly connected to the bidirectional lead screw 53. There are two clamping plates 56. The two clamping plates 56 are respectively fixedly connected to the two nut seats 55. The bearing seat 57 is fixedly connected to the base 51.

[0056] It is fixedly connected to the workbench 4 through the base 51. The base 51 serves as a support structure for installing various components. The two-way lead screw 53 is supported at both ends by two fixed seats 54. The two-way lead screw 53 is driven to rotate by the second motor 52, so that the two nut seats 55 on the two-way lead screw 53 approach or move away from each other. The two nut seats 55 respectively drive the two clamping plates 56 fixedly connected to them to move, so as to clamp or loosen the spinneret. The clamping plate 56 is provided with a V-shaped groove, so as to automatically position the circular spinneret while clamping. The provided bearing seat 57 is used to place the spinneret and cool the bottom of the spinneret at the same time.

[0057] As Figure 10 shown, the bearing seat 57 is provided with an empty groove 571, and the bearing seat 57 is provided with a plurality of water outlets 572. The empty groove 571 is connected to the water pump 71 through a pipeline.

[0058] By providing an empty groove 571 in the bearing seat 57 and connecting the empty groove 571 to the water pump 71 through a pipeline, the coolant is transported to the empty groove 571 through the water pump 71. The bearing seat 57 is provided with a plurality of water outlets 572, and the coolant sprays out from the water outlets 572, so as to cool the bottom of the spinneret. After the special-shaped holes of the spinneret are processed, the coolant is flushed from the bottom of the spinneret upwards, so that the debris at the bottom is washed out of the processed special-shaped holes, avoiding debris remaining in the holes and the need for secondary cleaning of the spinneret.

[0059] Working principle: The robotic arm 3 grabs the spinneret to be processed on the conveying mechanism 2 and transfers it to the bearing seat 57. The second motor 52 drives the bidirectional lead screw 53 to rotate, causing the two clamping plates 56 to approach each other, thereby clamping and positioning the spinneret. The controller 9 controls the main shaft 64 to drive the tool to rotate, and the linear module 62 drives the main shaft 64 to move downward, thereby drilling the spinneret. According to the different materials of the spinneret and each tool, and when the tool is processing a special-shaped hole, due to the changes in the shape of the hole and the processing path, the depth of the main shaft 64 sliding into the sliding groove 631 is different, so that the compression amount of the conical spring 663 is different, causing the piezoelectric ceramic sheet 662 to generate currents with different voltages. The electrode 661 conveys the current to the controller 9, and the controller 9 adjusts the rotation speed of the main shaft 64 according to the current. At the same time, the controller 9 controls the moving mechanism 8 to drive the workbench 4 to move along a specific trajectory, causing the positioning mechanism 5 and the spinneret to be processed to move, thereby realizing the processing of special-shaped holes. At the same time, the coolant in the water tank 74 is conveyed to the cooling nozzle 72 by the water pump 71, and the coolant is ejected through the cooling nozzle 72 to cool the special-shaped holes during the processing of the spinneret. The first motor 762 drives the first gear 763 to drive the second gear 764 to rotate along the tool, causing the cooling nozzle 72 to rotate along the tool, thereby changing the flushing angle of the special-shaped holes during processing. The bottom of the spinneret is cooled by the bearing seat 57. The used coolant flows through the through hole 42, into the collection tank 41 and then into the filter 73, and after filtering the debris in the coolant, it flows back into the water tank 74 again, realizing the recycling of the coolant. After the processing is completed, the controller 9 controls the robotic arm 3 to move the spinneret to another conveying mechanism 2 for conveying away, thereby realizing the automation of the special-shaped hole processing of the spinneret.
