Description

Technical Field

[0001] This invention relates to the field of generator rotor machining technology, and more specifically, to a servo-driven generator rotor milling device. Background Technology

[0002] Servo-driven generator rotor milling equipment is a special processing equipment used to process grooves on the outer periphery of generator rotors, ensuring the rotor's shape accuracy and groove consistency. It also ensures that the rotor does not move or deviate during the milling process, ensuring stable operation of the milling tool and orderly discharge of waste, thereby improving the rotor's processing accuracy and surface quality. Servo drive is just one of the driving methods in the milling equipment. However, milling cutters in milling machines are prone to bending due to continuous cutting impact, frictional heat during processing, chip wear, or installation deviations. Therefore, in order to avoid the decrease in machining accuracy, scrapping of rotor products, and further damage to the cutters caused by tool bending, it is necessary to inspect the milling cutters regularly. However, most traditional generator rotor milling devices do not integrate dedicated milling tool straightness and coaxiality detection structures. They are often observed manually, resulting in low detection accuracy, high subjectivity, inability to accurately identify minute bending deformations of the tool, low detection efficiency, high labor costs, and easy to miss or misdetect, which can easily lead to rotor slot shape deviations and machining scrap. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a servo-driven generator rotor milling device. This addresses the issue that in existing technologies, the detection of tool straightness and coaxiality relies on manual visual observation, resulting in low detection accuracy, poor efficiency, and a tendency to cause rotor machining errors and scrap.

[0004] The purpose and effectiveness of the servo-driven generator rotor milling device of the present invention are achieved by the following specific technical means: This invention provides a servo-driven generator rotor milling device, including a worktable, a transfer structure on the worktable, a placement area and a milling area on the worktable, a moving table mounted on the transfer structure, the moving table moving between the two areas via the transfer structure, and a fixing part on the moving table, the rotor body being fixed on the fixing part of the moving table.

[0009] According to a preferred embodiment, a third gear is provided inside the gearbox. The third gear is connected to the gearbox through a sliding structure. The third gear can mesh or disengage with the second gear through the sliding structure. An auxiliary motor is provided on the gearbox. The shaft end of the auxiliary motor is connected to the third gear. Through the arrangement of the first gear, the second gear, and the third gear, the gearbox can be configured into a normal state and a reinforced state. The normal state of the gearbox is represented as follows: the first gear is engaged with the second gear, and the second gear is not connected to the third gear. The enhanced state of the gearbox is represented as follows: the second gear meshes with the first gear and the third gear simultaneously, and the second gear is driven to rotate by the servo motor and the auxiliary motor at the same time.

[0010] According to a preferred embodiment, the top surface of the moving table is flush with the top surface of the milling platform, and the top surfaces of the first baffle and the second baffle are flush. The waste collection assembly includes a first air outlet pipe and a second air outlet pipe, both of which are installed on the milling platform and the air outlet direction is towards the milling space. The first air outlet pipe extends along the length direction of the milling platform, and the second air outlet pipe extends along the width direction of the milling platform. Both the first air outlet and the second air outlet are provided with a first air outlet and a second air outlet. The second air outlet is located above the first air outlet, and the air velocity at the second air outlet is greater than that at the first air outlet. A drop trough is provided at one end of the milling platform. The drop trough is distributed parallel to the first air outlet pipe, and a collection box is provided below the drop trough to collect iron filings and waste materials falling from the drop trough.

[0011] According to a preferred embodiment, a third air outlet pipe is provided above the milling platform. The third air outlet pipe is installed on the first baffle. Air is discharged through the third air outlet pipe to form an airflow curtain. The airflow curtain is in contact with the top surfaces of the first baffle and the second baffle. The length of the third air outlet duct is greater than the length of the first baffle.

[0012] According to a preferred embodiment, the detection assembly includes a support platform and a rotating disk. The support platform is mounted on the worktable and located within the detection area. The rotating disk is rotatably connected to the support platform, and a rotating motor for driving the rotating disk to rotate relative to the support platform is provided at the bottom of the support platform. The milling cutter can be moved to directly above the center point of the rotating disk through the feed drive mechanism. The rotating disk is equipped with a laser for emitting laser beams and a detection camera for capturing the laser beam and the contour of the milling tool. When the milling tool is located directly above the center point of the rotating disk, the milling tool, the laser, and the detection camera are on the same horizontal line. A backlight panel is set on the other side of the rotating disk opposite the detection camera, and the surface of the backlight panel is coated with a pigment layer.

[0013] According to a preferred embodiment, a robotic arm is installed on the worktable, a detection sleeve is provided at one end of the robotic arm, and a plurality of detection parts are provided inside the detection sleeve. The detection sleeve can be sleeved on the milling cutter by the robotic arm. The detection unit includes a mounting ring and several trigger blocks. The mounting ring is located inside the detection sleeve, and the trigger blocks are arranged around the circumference of the mounting ring and connected to the mounting ring through a telescopic structure. During the detection process, the milling cutter passes through the mounting ring and is located between multiple sets of trigger blocks. A pressure sensor is installed on the corresponding trigger block on the mounting ring side, and a contact element is provided on one side of the trigger block, which can contact the pressure sensor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This application, by dividing the milling area into a separate inspection zone and configuring an inspection component within that zone to detect the straightness and coaxiality of the milling cutter, enables the identification of the shape and installation status of the milling cutter before and after milling operations or during machining intervals, eliminating the need for manual visual inspection. This structure can detect minute bending or runout of the cutter, reducing subjective biases caused by manual inspection, decreasing the probability of missed or false detections, and facilitating timely detection of cutter anomalies and appropriate corrective measures. This alleviates problems such as rotor slot machining errors and finished product scrap caused by cutter deformation, thereby improving the stability of the milling process and the finished product qualification rate.

[0015] This application employs a movable moving stage in conjunction with a fixed clamping block, a pre-tensioning rubber strip, and a reinforcing airbag structure, enabling multi-segment positioning and auxiliary reinforcement of the rotor body. The fixed clamping block, driven by a first electric cylinder, adaptively conforms to the rotor surface, and with the deformation compensation of the pre-tensioning rubber strip, improves the fit and stability of the rotor during clamping. After the moving stage enters the milling platform, the reinforcing airbag extends into the moving slot to provide auxiliary support for the fixed clamping block, reducing the possibility of workpiece or clamping structure shaking or shifting during milling, ensuring the rotor maintains a relatively stable posture during milling, and improving the reliability of the milling process.

[0016] This application utilizes a servo motor in conjunction with an auxiliary motor and a switchable gear set to select either single-power drive or dual-power drive based on the milling load, thereby enhancing the device's ability to handle different cutting conditions. Simultaneously, the milling space is formed by the first and second baffles, and the airflow cooling and chip removal structure formed by multiple sets of air ducts can directionally blow the milling chips to the drop trough and into the collection box, reducing chip splashing and accumulation, and minimizing the scratching effect of chips on the tool and workpiece surface. The airflow can also cool the cutting area, improve the milling environment, and help extend the continuous working time of the tool. Attached Figure Description

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0020] Example: Figures 1 to 12 As shown, the present invention provides a servo-driven generator rotor milling device, including a worktable 11. The worktable 11 serves as the mounting base for the entire device, supporting and fixing the other functional components, and providing stable support conditions for the operation of the device.

[0021] The device includes a movable stage 21, and a transfer structure is provided on the worktable 11. The transfer structure provides the movable stage 21 with a moving path and moving power. The transfer structure can be a lead screw slide, which is a conventional technology that can drive the movable stage 21 to move smoothly between the placement area and the milling area, ensuring that the movable stage 21 does not shake significantly during the movement, keeping the rotor body 12 stable during the transfer process. At the same time, it can realize the displacement adjustment of the movable stage 21, ensuring that the movable stage 21 can be accurately locked into the stop slot 33 of the milling platform 31 to meet the positioning requirements of subsequent milling processing.

[0022] The worktable 11 is divided into a placement area and a milling area. The placement area is used for loading and unloading the rotor body 12, while the milling area is used for milling the rotor body 12. A movable table 21 is mounted on a transfer structure and can move between the placement and milling areas under the drive of the transfer structure, enabling the transfer of the rotor body 12 between different workstations. The movable table 21 has a fixing part for constraining and positioning the rotor body 12. The rotor body 12 is secured to the fixing part of the movable table 21, maintaining relative stability during transfer and processing.

[0023] The device includes a servo drive assembly and a milling platform 31. A support frame 13 is located within the milling area, providing a mounting carrier and support for the upper moving parts. A feed drive mechanism 14 is mounted on the support frame 13, driving the servo drive assembly to achieve multi-directional displacement adjustment. The servo drive assembly is mounted on the feed drive mechanism 14, providing power output for the milling operation. A milling cutter 15 is mounted at the bottom of the servo drive assembly, rotating under its drive to complete the milling of the rotor body 12. The milling platform 31 is mounted on the worktable 11, providing a machining positioning base for the moving stage 21. When the moving stage 21 is located within the milling area, it is engaged within the milling platform 31, placing the rotor body 12 within the designated machining area.

[0024] The device encloses a milling space. A first baffle 32 is provided on the top of the milling platform 31 and is arranged along the edge of the milling platform 31. A second baffle 22 is provided on the top of the moving table 21. The second baffle 22 cooperates with the first baffle 32 to enclose the milling space. The milling space is used to limit the range of iron filings splashing during the milling process and to concentrate the iron filings in a limited area.

[0025] The device is equipped with a waste collection component, which is installed on the milling platform 31. The waste collection component is used to blow, transport and collect the iron filings generated during the milling process, thereby reducing the accumulation of iron filings in the processing area.

[0026] The device also includes a detection component. The milling area is divided into detection zones, and the detection component is installed in the detection zones. The detection component is used to detect the straightness and coaxiality of the milling cutter 15. It can identify the shape and installation status of the milling cutter 15 before and after the milling operation, so as to detect the bending of the milling cutter 15 in time. This can effectively avoid the deviation of the rotor groove machining dimensions and abnormal groove wall morphology caused by the bending or wobble of the cutter, as well as further aggravate the damage of the cutter and affect the workpiece machining qualification rate.

[0027] like Figures 2 to 7As shown, the fixing part includes several fixing blocks 23, which are symmetrically distributed on the top surface of the moving table 21 and paired in pairs to form fixing claws. Multiple sets of fixing claws are arranged sequentially along the moving direction of the moving table 21. This arrangement can achieve multi-point and multi-segment constraint on the rotor body 12. The rotor body 12 is clamped between each set of fixing claws. Through the clamping action of the fixing claws, the rotor body 12 is kept relatively fixed on the moving table 21, preventing the rotor body 12 from shifting or shaking during transportation or milling.

[0028] Each fixed block 23 on the moving table 21 is provided with a moving groove 24. The extending direction of the moving groove 24 is consistent with the moving direction of the fixed block 23. The fixed block 23 is locked in the corresponding moving groove 24 and can slide freely along the moving groove 24. By sliding the fixed block 23 in the moving groove 24, the fixed claws that are paired together can move closer or further away from each other, thereby forming a gripping state and a loosening state. When the fixed claws are in the gripping state, they can effectively clamp the rotor body 12. When the fixed claws are in the loosening state, it is convenient to load and unload the rotor body 12, which meets the station switching requirements in the processing process.

[0029] The moving table 21 is provided with several mounting parts, each corresponding to a fixed clamping block 23. The mounting parts provide mounting positions for the first electric cylinder 25, ensuring that the first electric cylinder 25 does not shift during operation. The first electric cylinder 25 is mounted on the mounting part, and the shaft end of the first electric cylinder 25 is fixedly connected to the fixed clamping block 23. As the driving component of the fixed clamping block 23, the first electric cylinder 25 can output linear power to drive the fixed clamping block 23 to move smoothly along the moving groove 24, realizing the switching between the gripping and releasing states of the fixed clamping claws. This eliminates the need for manual adjustment, reducing labor intensity, and ensures the stability of the fixed clamping block 23 during movement, avoiding clamping deviations caused by manual adjustment.

[0030] The side of the fixing block 23 facing the rotor body 12 is designated as the contact surface 26. The contact surface 26 is the part where the fixing block 23 directly contacts the rotor body 12. Through the close contact between the contact surface 26 and the rotor body 12, the contact area between the fixing block 23 and the rotor body 12 is increased, improving the clamping stability. The surface of the contact surface 26 is provided with anti-slip texture, which can increase the friction between the contact surface 26 and the rotor body 12, reduce the relative sliding between the rotor body 12 and the fixing block 23, further improve the clamping effect, and ensure that the rotor body 12 remains stable during processing. At the same time, it can also be used on the contact surface. A rubber pad is covered by the contact surface 26. The rubber pad is fixedly connected to the contact surface 26 and covers the entire contact area of ​​the contact surface 26. The rubber pad has a certain elasticity. When the fixing block 23 clamps the rotor body 12, the rubber pad contacts the rotor body 12 first, which can reduce the rigid contact with the rotor body 12 and avoid surface scratches, indentations and other damage caused by the rigid contact surface 26 of the fixing block 23 directly contacting the surface of the rotor body 12. At the same time, the rubber pad can further increase the friction between the rubber pad and the rotor body 12, and together with the anti-slip texture, improve the clamping stability and help the fixing block 23 to better clamp and fix the rotor body 12.

[0031] A pre-tightening rubber strip 27 is provided on the contact surface 26 of the fixing block 23. The pre-tightening rubber strip 27 extends along the length of the fixing block 23, and both ends of the pre-tightening rubber strip 27 are fixedly connected to the fixing block 23, which can ensure that the pre-tightening rubber strip 27 will not fall off during use. At the same time, a groove 28 is provided on the contact surface 26. The size of the groove 28 is adapted to the pre-tightening rubber strip 27 to accommodate the pre-tightening rubber strip 27 and provide space for the deformation of the pre-tightening rubber strip 27.

[0032] When the fixing claws are in the released state, the contact surface 26 is not in contact with the rotor body 12. At this time, the pre-tightening rubber strip 27 is in its natural state, protruding from one side of the contact surface 26. In this way, when the fixing claws begin to grip the rotor body 12, the pre-tightening rubber strip 27 can first contact the rotor body 12, playing a role in initial pre-tightening and positioning, which facilitates the subsequent clamping operation of the fixing block 23. At the same time, after the fixing block 23 contacts the rotor body 12, due to the rebound force of the pre-tightening rubber strip 27, it further presses and squeezes the rotor body 12, forming an auxiliary constraint and reducing the gap between the rotor body 12 and the fixing block 23. Thus, the fixing of the rotor body 12 is carried out by both the pre-tightening rubber strip 27 and the fixing block 23. The rigid clamping of the fixing block 23 can be used to achieve stable positioning, and the elasticity of the pre-tightening rubber strip 27 can be used to achieve buffering and contact, preventing the rotor body 12 from shifting or deviating during transportation or milling.

[0033] When the clamping jaws are in the gripping state, the contact surface 26 is in contact with the rotor body 12, and the rotor body 12 exerts a compressive force on the pre-tightening rubber strip 27, causing the pre-tightening rubber strip 27 to undergo elastic deformation and then be recessed in the groove 28. After the pre-tightening rubber strip 27 undergoes elastic deformation, it will generate a rebound force. This rebound force acts on the surface of the rotor body 12, which further fixes the rotor body 12, fills the tiny gap between the contact surface 26 and the rotor body 12, improves the stability of clamping, and ensures that the rotor body 12 does not move during the milling process.

[0034] like Figure 4 As shown, the milling platform 31 has a stop groove 33, which is used to limit the position of the moving stage 21. The moving stage 21 is locked in the stop groove 33, keeping it relatively fixed during milling and reducing the possibility of displacement caused by external forces. A receiving groove 34 is provided on the milling platform 31 corresponding to the moving groove 24 on the moving stage 21. The receiving groove 34 provides space for the reinforcing airbag 35, preventing it from interfering with the normal entry and exit of the moving stage 21. The reinforcing airbag 35 is installed inside the receiving groove 34. The device is equipped with an air pump, which is connected to the reinforcing airbag 35 through a pipeline. The air pump can supply gas into the reinforcing airbag 35 or discharge internal gas, thus enabling the inflation and deflation of the reinforcing airbag 35. A limiting structure is provided between the reinforcing airbag 35 and the milling platform 31. The limiting structure is used to constrain the expansion direction of the reinforcing airbag 35, so that the reinforcing airbag 35 can stably extend towards the stop groove 33 after inflation.

[0035] The reinforcing airbag 35 has two working states: an inflated state and a flat state. When the moving table 21 is fully inserted into the stopping slot 33 and the air pump inflates the reinforcing airbag 35, the reinforcing airbag 35 gradually expands and switches to the inflated state. At this time, the reinforcing airbag 35 extends outward from the receiving slot 34 and into the moving slot 24 on the moving table 21 until it contacts the fixing block 23 in the moving slot 24. The compressive force generated by the expansion of the reinforcing airbag 35 acts on the fixing block 23, providing additional clamping force to the fixing block 23 and assisting the fixing block 23 in clamping the rotor body 12. At the same time, the reinforcing airbag 35 extends into the moving table 21, providing additional limiting force to the moving table 21 and reducing the possibility of the moving table 21 shaking or moving during processing.

[0036] On the other hand, the reinforcing airbag 35 can effectively fill the gap in the moving slot 24, preventing iron filings and waste generated during the milling of the rotor body 12 from falling into the device from the moving slot 24, causing internal structural jamming, component wear or pipeline blockage, etc., and reducing the probability of device failure.

[0037] When the air pump discharges the gas from the reinforcing airbag 35, the reinforcing airbag 35 gradually contracts and switches to a flat state. At this time, the reinforcing airbag 35 is completely stored inside the storage groove 34 and no longer contacts the fixed block 23 and the moving table 21. This releases the limiting effect on the fixed block 23 and the moving table 21, allowing the moving table 21 to be smoothly moved out of the stop groove 33 to complete the unloading or station switching action.

[0038] In a further embodiment, a storage tank and a water pump are installed within the device. The storage tank is filled with coolant, and the water pump is connected to both the storage tank and the reinforcing airbag 35 via pipelines. The coolant is used as a pressurizing medium to deliver the coolant into the reinforcing airbag 35, thereby enabling the filling and emptying of the airbag 35. After the coolant enters the reinforcing airbag 35, it inflates and applies outward pressure to the fixing block 23 and the moving table 21, improving the clamping and limiting effect. After processing is completed, the water pump can pump the coolant back into the storage tank, causing the airbag 35 to contract and return to its original position. Using coolant as a pressurizing medium can simultaneously pressurize the airbag 35 and cool it down, extending its service life. It can also reduce the impact of heat transferred from the milling area on the airbag 35 to a certain extent, ensuring the stable operation of the airbag 35.

[0039] like Figure 8 , Figure 9 As shown, the servo drive assembly includes a drive platform 41 and a lifting platform 42. The drive platform 41 serves as the mounting base for the servo drive assembly and is fixedly connected to the feed drive mechanism 14 on the support frame 13. Under the drive of the feed drive mechanism 14, it can achieve multi-directional horizontal displacement, thereby driving the entire servo drive assembly and the milling cutter 15 to adjust their positions to meet the milling requirements of different positions on the rotor body 12. The lifting platform 42 is located below the drive platform 41 and is mainly used to install the gearbox 46 and the milling cutter 15, receiving the driving power and transmitting it to the milling cutter 15. Several limiting rods 43 are provided around the lifting platform 42. The limiting rods 43 are fixedly connected to the lifting platform 42. Each limiting rod 43 has a limiting hole 44 on the drive platform 41. The size of the limiting hole 44 is adapted to the limiting rod 43. The limiting rod 43 passes through the corresponding limiting hole 44, so that the lifting platform 42 and the drive platform 41 form a sliding connection. The limiting rod 43 and the limiting hole 44 cooperate with each other to constrain the movement direction of the lifting platform 42, ensuring that the lifting platform 42 can only move up and down along the extension direction of the limiting rod 43, avoiding the lifting platform 42 from deviating or shaking during the lifting process, and ensuring the stability of the position of the milling cutter 15.

[0040] Several second electric cylinders 45 are provided between the drive platform 41 and the lifting platform 42. The second electric cylinders 45 are evenly distributed between the drive platform 41 and the lifting platform 42. The second electric cylinders 45 are fixedly installed on the bottom surface of the drive platform 41, and their shaft ends are fixedly connected to the top surface of the lifting platform 42. As the driving component of the lifting platform 42, the second electric cylinders 45 can output linear power and drive the lifting platform 42 to move up and down along the limit rod 43 through their own telescopic movement, thereby realizing the lifting movement of the lifting platform 42, adjusting the height of the milling cutter 15 to adapt to the milling requirements of rotor bodies 12 of different sizes, and also controlling the cutting distance between the milling cutter 15 and the rotor body 12 to meet the depth requirements of milling.

[0041] A gearbox 46 is mounted on the lifting platform 42. The gearbox 46 is fixedly installed on the bottom surface of the lifting platform 42 to house and protect the internal gear structure. It also provides a mounting platform for the servo motor and auxiliary motor, preventing the gear structure from being corroded by iron filings and coolant, thus ensuring the stability of power transmission. The gearbox 46 contains a first gear and a second gear, both rotatably connected to the gearbox 46 via rotating shafts. The first and second gears mesh with each other to transmit power. A servo motor is mounted on the side of the gearbox 46, with its output shaft fixedly connected to the first gear. As the main power source, the servo motor outputs rotational power, driving the first gear to rotate. Through the meshing transmission between the first and second gears, the second gear rotates synchronously. A rotating shaft extends from the second gear and is fixedly connected to the second gear. The rotating shaft passes through the bottom surface of the gearbox 46. The end of the rotating shaft is connected to the milling cutter 15 through a quick-locking structure. The quick-locking structure is used to realize the quick installation and removal of the milling cutter 15, which facilitates the replacement and maintenance of the milling cutter 15. At the same time, it can ensure the connection stability between the rotating shaft and the milling cutter 15, so that the rotational power of the rotating shaft can be stably transmitted to the milling cutter 15, driving the milling cutter 15 to rotate and complete the milling operation.

[0042] The gearbox 46 also contains a third gear, which is connected to the gearbox 46 via a sliding structure. This sliding structure allows the third gear to slide within the gearbox 46, thereby enabling the third gear to mesh or disengage with the second gear. An auxiliary motor is mounted on the gearbox 46, fixedly installed on the other side. Its output shaft is fixedly connected to the third gear, providing rotational power to it. Through the coordinated arrangement of the first, second, and third gears, the gearbox 46 can operate in two states: a normal state and a reinforced state, to adapt to different milling load requirements.

[0043] The normal state of gearbox 46 is as follows: the first gear and the second gear are engaged, and the second gear and the third gear are disengaged. At this time, only the servo motor works. The servo motor drives the first gear to rotate. Through the meshing transmission between the first gear and the second gear, the second gear and the rotating shaft are driven to rotate, which in turn drives the milling cutter 15 to rotate. This state is suitable for milling scenarios with low load, which can save energy and reduce the operating loss of the device.

[0044] The enhanced state of gearbox 46 is represented as follows: the sliding structure drives the third gear to move, so that the second gear meshes with the first gear and the third gear at the same time. At this time, the servo motor and the auxiliary motor start at the same time. The servo motor drives the first gear to rotate, and the auxiliary motor drives the third gear to rotate. The two power sources act on the second gear at the same time through the first gear and the third gear, driving the second gear and the rotating shaft to rotate at high speed, thereby driving the milling cutter 15 to rotate with greater power. This state is suitable for milling scenarios with heavy loads, which can improve milling efficiency and ensure smooth milling.

[0045] The gearbox 46 is also equipped with a conventional gear lubrication structure, which can effectively reduce the friction and wear generated during the meshing rotation of the first gear, the second gear, and the third gear, reduce the running resistance between the gears, extend the service life of the gears and the internal components of the gearbox 46, and at the same time reduce the heat generated when the gears are running at high speed to a certain extent, so that the gearbox 46 can maintain a stable working state.

[0046] like Figures 3 to 6 As shown, the top surface of the moving table 21 is flush with the top surface of the milling platform 31, and the top surfaces of the first baffle 32 and the second baffle 22 are flush. The flush arrangement can form a continuous enclosure structure between the first baffle 32 and the second baffle 22, reducing gaps and facilitating the blocking of debris generated during milling, so that the debris is concentrated in a limited area, which is convenient for subsequent cleaning and collection.

[0047] The waste collection assembly includes a first air outlet duct 51 and a second air outlet duct 52, both of which are mounted on the milling platform 31. Both outlet ducts face inwards towards the milling space, delivering airflow to the machining area to agitate debris. The first air outlet duct 51 extends along the length of the milling platform 31, covering the length of the milling space; the second air outlet duct 52 extends along the width of the milling platform 31, covering the width of the milling space. Together, they can sweep away debris from different areas within the milling space.

[0048] Both the first air outlet 51 and the second air outlet 52 are equipped with a first air outlet 53 and a second air outlet 54. The second air outlet 54 is located above the first air outlet 53, and the air velocity at the second air outlet 54 is greater than that at the first air outlet 53. The lower first air outlet 53 outputs airflow that can push the chips in the milling space forward; the upper second air outlet 54 outputs a faster airflow that can form a barrier above the chips, preventing the chips from drifting upwards and keeping the chips within a lower height range, thus improving the chip collection effect.

[0049] A drop trough 55 is provided at one end of the milling platform 31. The drop trough 55 is parallel to the first air outlet duct 51, providing a falling channel for debris. A collection box is provided below the drop trough 55 to receive and collect the iron filings and waste falling from the drop trough 55, preventing debris from scattering outside the device or into the internal structure. When cleaning debris, the second air outlet duct 52 is first activated, and the airflow output from the second air outlet duct 52 gathers the scattered debris in the milling space towards the side closer to the drop trough 55; then the first air outlet duct 51 is activated, and the airflow output from the first air outlet duct 51 blows the gathered debris into the drop trough 55, allowing the debris to enter the collection box along the drop trough 55 for collection.

[0050] A third air outlet duct 56 is installed above the milling platform 31. The third air outlet duct 56 is mounted on the first baffle 32. When in operation, the third air outlet duct 56 outputs airflow outward, forming an airflow curtain on the top surfaces of the first baffle 32 and the second baffle 22. This airflow curtain adheres closely to the top surfaces of the first baffle 32 and the second baffle 22, further preventing debris from flying outward from the top of the enclosure and improving the debris containment effect. The length of the third air outlet duct 56 is greater than the length of the first baffle 32, which expands the coverage area of ​​the airflow curtain, allowing it to simultaneously cover the top areas of both the first baffle 32 and the second baffle 22, enhancing the overall blocking effect.

[0051] At the same time, the milling cutter 15 will pass through the air curtain during its ascent, which can effectively blow off the iron filings, debris and coolant residue attached to the milling cutter 15, reduce the foreign objects carried upward with the milling cutter 15, reduce the possibility of debris drifting outside the processing area, and also help maintain the working condition of the milling cutter 15.

[0052] A conventional chip blowing structure is also provided near the milling cutter 15, which can blow the chips on the surface of the rotor body 12 to the bottom of the milling space during the operation of the milling cutter 15. Then, through the airflow formed by the first air outlet 51 and the second air outlet 52, the chips at the bottom are gradually pushed into the drop groove 55 and finally enter the collection box for centralized collection, so as to avoid the accumulation of chips in the processing area.

[0053] like Figure 2 , Figure 10 , Figure 11 As shown, the detection assembly includes a support platform 601 and a rotating disk 602. The support platform 601 is fixedly mounted on the worktable surface 11 and is located in the detection area within the milling zone. The support platform 601 provides stable support for the rotating disk 602 and related detection components. The rotating disk 602 is rotatably connected to the support platform 601 and can rotate circumferentially above the support platform 601. A rotary motor is provided at the bottom of the support platform 601, which outputs rotational power to drive the rotating disk 602 to rotate smoothly relative to the support platform 601. The milling cutter 15 can be moved to a position directly above the center point of the rotating disk 602 under the drive of the feed drive mechanism 14, so that the milling cutter 15 enters the detection area, providing positional conditions for subsequent detection steps.

[0054] A laser 603 and a detection camera 604 are mounted on the rotating disk 602. The laser 603 emits a straight laser beam upwards, positioned on one side of the milling cutter 15 body, parallel to each other. The rotating disk 602 is rotated by a motor, changing the position of the laser beam and allowing it to move circumferentially around the milling cutter 15. This allows for the acquisition of the shape of the milling cutter 15 at multiple circumferential angles, identifying the bending of the milling cutter 15 in different directions, and achieving comprehensive inspection of the overall shape of the cutter. The laser 603 can be a Keyence LV-H62 laser. The detection camera 604 synchronously acquires images of the relative position of the laser beam and the milling cutter 15. Based on the laser beam's obstruction and image changes, it determines whether the milling cutter 15 has significant bending. This structure is suitable for detecting cutters with large degrees of bending and can directly reflect the shape deviation of the cutter. The detection camera 604 can be a Keyence CV-H500C camera.

[0055] A backlight plate 605 is provided on the opposite side of the rotating disk 602 relative to the detection camera 604. The surface of the backlight plate 605 is coated with a pigment layer, which can improve the background contrast and make it easier for the detection camera 604 to more clearly identify the contour of the milling tool 15. This structure is mainly used to detect milling tools 15 with a large degree of curvature. By using laser illumination and image acquisition, the curvature state of the tool can be intuitively reflected.

[0056] A robotic arm 606 is also mounted on the worktable 11. The robotic arm 606 can be adjusted in multiple directions and can move the end effector to a designated position. A detection sleeve 607 is provided at the end of the robotic arm 606 away from the worktable 11. The detection sleeve 607 is used to accommodate and realize the detection of minute bending of the milling cutter 15. The detection sleeve 607 has several detection parts inside, which are used to contact the surface of the milling cutter 15 to sense the minute deformation of the cutter.

[0057] The detection unit includes a mounting ring 608 and several trigger blocks 609. The mounting ring 608 is fixedly disposed inside the detection sleeve 607, providing a mounting base for the trigger blocks 609 and related components. The trigger blocks 609 are evenly arranged along the circumference of the mounting ring 608, and are connected to the mounting ring 608 via a telescopic structure. This telescopic structure allows the trigger blocks 609 to perform small-range telescopic movements. During the detection process, the milling cutter 15 passes through the mounting ring 608 and is positioned between the multiple sets of trigger blocks 609, allowing the trigger blocks 609 to contact the outer peripheral surface of the milling cutter 15.

[0058] A pressure sensor 610 is installed on the periphery of the mounting ring 608 corresponding to the position of each trigger block 609. The pressure sensor 610 is used to sense contact pressure and generate a corresponding signal. The pressure sensor 610 can be a Panasonic CZ-101A pressure sensor. A contact element 611 is provided on the side of the trigger block 609 near the pressure sensor 610. The contact element 611 can make contact with the pressure sensor 610 as the trigger block 609 moves. When the milling tool 15 has a slight bend, it will push the trigger block 609 at the corresponding position to move, causing the contact element 611 to press against the pressure sensor 610. After receiving the pressure signal, the pressure sensor 610 can determine that there is a slight deformation of the tool. This structure is mainly used to detect milling tools 15 with a small degree of bend, improving the comprehensiveness of tool condition identification.

[0059] Specific usage instructions: I. Milling Process Loading and positioning: Start the lead screw slide of the transfer structure to move the moving table 21 to the placement area. Control the first electric cylinder 25 to move the fixing blocks 23 away from each other along the moving groove 24, so that the fixing claws are in a loose state. Place the rotor body 12 between the fixing claws of the moving table 21. Start the first electric cylinder 25 again to move the fixing blocks 23 closer to each other until the contact surface 26 is in contact with the rotor body 12. The pre-tightening rubber strip 27 is squeezed and recessed into the groove 28. The rotor body 12 is fixed by the rebound force of the pre-tightening rubber strip 27 and the rigid clamping of the fixing blocks 23. If the contact surface 26 is covered with a rubber pad, the surface of the rotor body 12 can be further protected from damage.

[0060] Transfer and Positioning: Start the lead screw slide to smoothly move the moving table 21 to the milling area, so that the moving table 21 is engaged in the stopping slot 33 of the milling platform 31, ensuring that the top surface of the moving table 21 is flush with the top surface of the milling platform 31 and the top surface of the second baffle 22 is flush with the top surface of the first baffle 32, forming a closed milling space. Start the air pump (or water pump) to fill the reinforcing airbag 35 with gas (or coolant), so that the reinforcing airbag 35 extends from the receiving slot 34 into the moving slot 24, contacts the fixing block 23 and applies pressure, assisting the fixing block 23 in clamping the rotor body 12, while restricting the movement of the moving table 21 and filling the gap in the moving slot 24 to prevent iron filings from falling.

[0061] Milling Operation: Based on the milling requirements of the rotor body 12, the servo drive assembly is moved as a whole by the feed drive mechanism 14 to adjust the horizontal position of the milling cutter 15. The second electric cylinder 45 is activated, driving the lifting platform 42 to move up and down along the limit rod 43 to adjust the cutting distance between the milling cutter 15 and the rotor body 12. The working state of the gearbox 46 is selected according to the milling load. When the load is small, it switches to the normal state, only the servo motor is activated, and the milling cutter 15 is rotated through the meshing transmission of the first gear and the second gear. When the load is large, it switches to the enhanced state, the servo motor and the auxiliary motor are activated, and the second gear is driven to rotate through the first gear and the third gear, driving the milling cutter 15 to rotate with greater power. The chip blowing structure near the milling cutter 15 is activated to blow the chips on the surface of the rotor body 12 to the bottom of the milling space in time. The coolant circulation system is activated, and the water pump delivers the coolant in the storage tank to the milling area to cool the milling cutter 15 and the rotor body 12, and at the same time assists in flushing away iron chips. After use, the coolant flows back to the storage tank for recycling. With the cooperation of the feed drive mechanism 14 and the servo drive assembly, the milling cutter 15 completes the milling of the rotor body 12. During the machining process, the lubrication structure in the gearbox 46 continues to work, reducing gear wear and ensuring stable power transmission.

[0062] Material unloading operation: After milling is completed, shut down the milling cutter 15, the chip blowing structure, and the coolant circulation system. Start the air pump (or water pump) to draw back the gas (or coolant) in the reinforcing airbag 35, causing the reinforcing airbag 35 to retract into the receiving groove 34, thus releasing the limits on the fixed block 23 and the moving table 21. Start the first electric cylinder 25 to move the fixed block 23 away from each other, releasing the rotor body 12. Start the lead screw slide to move the moving table 21 to the placement area, remove the machined rotor body 12, and complete one milling operation.

[0063] II. Cleaning Process The cleaning process is divided into real-time cleaning during the milling process and centralized cleaning after each milling operation, ensuring that there is no accumulation of iron filings in the milling space to avoid affecting subsequent processing and component operation.

[0064] Real-time cleaning: During the milling operation, the chip blowing structure works continuously, blowing the chips on the surface of the rotor body 12 to the bottom of the milling space; the third air outlet 56 is continuously activated, outputting airflow to form an airflow curtain, which adheres to the top surfaces of the first baffle 32 and the second baffle 22, preventing chips from flying out from the top of the enclosure. At the same time, as the milling cutter 15 rises, when it passes through the airflow curtain, the iron filings, debris and coolant residue attached to its surface are blown off, reducing chip dispersion.

[0065] Centralized Cleaning: After a single milling operation, the moving table 21 remains in the stop slot 33 (or is moved to a position that does not affect cleaning). The waste collection component is activated, and the second air outlet 52 is activated first in a preset sequence. Airflow is output through the first air outlet 53 and the second air outlet 54 of the second air outlet 52. The lower first air outlet 53 pushes the bottom debris, while the upper second air outlet 54 (with a higher air velocity than the first air outlet 53) prevents the debris from floating upwards, gathering the scattered debris in the milling space towards the side near the drop trough 55. Then, the first air outlet 51 is activated, and through the cooperation of its upper and lower air outlets, the gathered debris is blown into the drop trough 55, where it falls into the collection box below. After cleaning, the first air outlet 51, the second air outlet 52, and the third air outlet 56 are closed. The iron filings and waste in the collection box are cleaned regularly to ensure the normal operation of the collection component.

[0066] III. Testing Process The inspection process is divided into tool inspection before milling and tool inspection after milling. The inspection components comprehensively identify the straightness and coaxiality of the milling tool 15, and promptly detect tool bending to avoid affecting the machining quality. The inspection process must be carried out when there are no chips in the milling space and the milling tool 15 is in an idle state.

[0067] For detecting tools with significant curvature: The feed drive mechanism 14 is activated, moving the milling tool 15 directly above the center point of the rotating disk 602 in the detection area, ensuring that the milling tool 15, laser 603, and detection camera 604 are on the same horizontal line. The rotating motor at the bottom of the support platform 601 is activated, causing the rotating disk 602 to rotate smoothly. The laser 603 emits a straight laser beam upwards, parallel to the milling tool 15, and moves circumferentially around the milling tool 15 as the rotating disk 602 rotates. The detection camera 604 simultaneously acquires images of the relative position of the laser beam and the milling tool 15. The pigment layer on the surface of the backlight panel 605 enhances the background contrast, facilitating clear identification of the tool outline by the detection camera 604. Based on the laser beam's obstruction and image changes, it is determined whether the milling tool 15 has significant curvature.

[0068] For tools with minor bending: If no obvious bending is detected by the above inspection, the robotic arm 606 is activated and its posture is adjusted to move the detection sleeve 607 above the milling cutter 15. The milling cutter 15 is positioned within the mounting ring 608 inside the detection sleeve 607, between multiple sets of trigger blocks 609. The telescopic structure moves the trigger blocks 609 towards the milling cutter 15, bringing them into contact with the outer circumferential surface of the milling cutter 15. If the milling cutter 15 has a slight bending, it will push the corresponding trigger block 609 to move, causing the contact element 611 to press against the pressure sensor 610. Upon receiving the pressure signal, the pressure sensor 610 can determine that the tool has a slight deformation.

[0069] Post-inspection processing: After inspection, if the milling cutter 15 is found to be bent (regardless of degree), shut down the inspection assembly, remove the milling cutter 15 using the quick-lock mechanism, replace it with a qualified milling cutter 15, and re-inspect until the tool condition meets the requirements. If the inspection is qualified, shut down the inspection assembly, reset the milling cutter 15, and prepare for the next milling operation. After each inspection, clean up any small amount of debris in the inspection area to ensure that the laser 603, inspection camera 604, inspection sleeve 607, and other components of the inspection assembly are free of foreign objects to ensure the accuracy of subsequent inspections.
