Description

Technical Field

[0001] This invention relates to the field of dynamic balancing calibration technology, specifically to an intelligent dynamic balancing calibration platform for a snowplow impeller. Background Technology

[0002] The core components of the intelligent dynamic balancing calibration platform for snow blower impellers include an impeller clamping mechanism, dynamic balancing sensors, an intelligent control unit, an automatic calibration actuator, and a human-machine interface panel. The clamping mechanism secures impellers of different specifications. The sensors collect imbalance signals during impeller rotation in real time. The intelligent control unit processes the signals and analyzes the location and magnitude of the imbalance. The automatic calibration actuator precisely adjusts the counterweight or corrects the imbalance through cutting. The human-machine interface panel displays parameters and status. Its core function is to solve the vibration and noise problems caused by impeller imbalance during rotation, improve impeller operational stability, extend the service life of the snow blower and its components, reduce wear rate, minimize human error, improve calibration efficiency and accuracy, ensure uniform force distribution during high-speed impeller rotation, guarantee the safety and snow-throwing effect of the snow blower, avoid equipment failures caused by imbalance, and adapt to the batch calibration needs of impellers of different models, meeting the standardization requirements of production and maintenance.

[0003] The aforementioned and similar existing technologies, including the intelligent dynamic balancing calibration platform for snow blower impellers, have significant deficiencies in the processing of machining waste. They lack a dedicated waste recycling device, and milling waste adheres to the impeller surface, altering the actual mass distribution and making it impossible to accurately identify the true mass eccentricity defect during subsequent inspections. Furthermore, the adhered waste scratches the impeller's clamping and mating surfaces, affecting subsequent clamping accuracy. Waste splattering from cutting and welding counterweights not only pollutes the overall working environment but also easily splashes into the surrounding operating area, posing a safety threat to on-site personnel. The splattered waste can also impact and damage precision components of the equipment, and the scattered splattered waste requires frequent manual cleaning, significantly reducing the workload of batch impeller calibration. Inefficiency and other such drawbacks not only directly affect the normal operation of the equipment and the accuracy of dynamic balance testing and calibration, but also significantly increase the burden of manual operation, while bringing many safety hazards and equipment wear and tear problems. The lack of a dedicated recycling device makes it impossible to collect processing waste in a timely manner, which easily accumulates at the core components of the equipment such as clamps, spindles, and vibration sensors. Waste stuck in the fit gap between the clamp and the impeller will damage the clamping coaxiality, and covering the sensor detection area will cause the vibration data acquisition to be distorted, thus causing deviation in the dynamic balance test results. This makes the parameters for subsequent de-balancing calibration lose their scientific basis. After calibration, the impeller is still prone to violent vibration and noise due to unbalanced forces, and even the impeller may crack and fly off, which seriously affects the working stability and safety of the snow blower.

[0004] Therefore, the present invention provides an intelligent dynamic balancing calibration platform for snow blower impellers that can effectively suck up waste of different sizes, realize automatic waste collection, and avoid waste splashing and accumulation. Summary of the Invention

[0005] To address the problems of poor adaptability of waste recycling structures, incomplete collection, and high manual cleaning intensity in existing technologies, a smart dynamic balancing calibration platform for snow blower impellers has been designed.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a smart calibration platform for dynamic balancing of snow blower impeller, including a detection assembly and a detection component disposed on its inner side. The detection assembly includes a fixed clamp and a movable clamp, which are respectively clamped at both ends of the detection component. A base is fixed to the bottom of the fixed clamp, and the movable clamp is slidably connected to the inner side of the base. A driving component is disposed on the inner side of the base. A protective shell is fixed to the top of the base, and a hollow frame is fixed to the inner side of the protective shell. A controller is fixed to one side of the base, and a power box is fixed to the top of the end of the base near the controller.

The observation windows can also have ventilation openings to avoid the risk of vibration of the test piece caused by air pressure difference or turbulent eddies due to being enclosed near the test piece.

A splicing plate is detachably connected to the inside of the recyclable part.

[0012] Furthermore, the duct section includes an air chamber, a main pipe, and a regulating pipe. The air chamber is fixed to the bottom of the recovery unit via a corrugated pipe. The corrugated pipe is used to ensure communication between the air chamber and the air holes when the recovery unit vibrates. The main pipe is fixedly connected to the bottom of the air chamber. The other end of the main pipe is fixedly connected to the regulating pipe. The other end of the regulating pipe is fixedly connected to the output end of the negative pressure device. The negative pressure device is fixed to the top of the base via a connecting component. Multiple sets of air holes are provided, and each set of air holes is arranged in a circumferential array to ensure that the airflow covers the detection unit and its surrounding space.

[0013] Furthermore, the feed adjustment unit also includes a base, which is slidably engaged with the inner side of the transverse frame. The machining unit is fixed to the top of the bottom wall of the base. The output axis of the machining unit is on the same horizontal plane as the axis of the detection piece. A toothed plate is fixed to the bottom of the base. A bottom gear is rotatably connected to the bottom of the transverse frame. The bottom gear meshes with the toothed plate. A transmission rod is slidably engaged with the inner side of the bottom gear. Two limit frames are fixed to one side of the support. The two ends of the transmission rod are rotatably connected to the inner sides of the two limit frames. Side gears are fixed to both ends of the transmission rod. Two lifting plates are slidably connected to the inner sides of the two limit frames. The two lifting plates mesh with the two side gears respectively. Two side plates are fixedly connected to the bottom ends of the two lifting plates through connecting components. Teeth are opened on the inner sides of the two side plates. The two side plates are slidably engaged with the top of the base through connecting components. The butterfly plate is rotatably connected to the inner side of the adjustment tube through a sealed bearing. Two driven wheels are fixed to the two ends of the butterfly plate respectively. The two driven wheels mesh with the two side plates respectively.

[0014] The beneficial effects of this invention are:

[0015] (1) The intelligent calibration platform for dynamic balancing of snow blower impellers described in this invention employs a negative pressure device and air duct components with directional air holes for guidance. Before processing, the negative pressure device is activated to quickly create a stable negative pressure field around the test piece. Combined with multiple sets of circumferentially distributed air holes on the top of the recovery piece, it achieves complete coverage of the space surrounding the test piece, eliminating any suction dead zones. This ensures that all types of waste generated during processing, such as milling and cutting, can be captured. The directional guidance of the air holes alters the natural falling trajectory of the waste, preventing it from splashing onto the core components of the equipment due to inertia. This prevents equipment malfunctions caused by waste adhesion or jamming, reduces the probability of equipment wear, and extends the service life of the core components. Simultaneously, it effectively avoids waste splashing and contaminating the processing environment, reduces interference to workers during waste cleaning, eliminates the need for additional protective barriers and other auxiliary facilities, simplifies the processing site layout, indirectly reduces on-site management costs, and ensures the safe and efficient conduct of testing and calibration operations.

[0016] (2) The intelligent dynamic balancing calibration platform for snow blower impellers described in this invention adopts an adaptive structure that links the feed adjustment section with the butterfly plate of the air duct section. During processing, as the processing depth increases and the waste size increases, the telescopic component pushes the processing section to feed while simultaneously driving the butterfly plate to rotate through a series of transmission structures. This automatically reduces the proportion of the butterfly plate in the cross-section of the air duct section, increases the airflow channel area, and simultaneously enhances the suction capacity of the negative pressure device. This ensures that waste under different processing conditions can be stably suctioned, avoiding problems such as incomplete suction and waste accumulation caused by larger waste size or increased production. The recycling component adopts an inclined design and is equipped with an elastic component. After the waste falls to the top of the recycling component, it will disrupt its balance state and generate slight vibration under the action of the elastic component. This causes the waste to automatically slide down the inclined surface to the recycling tank under the action of gravity, realizing automatic collection of waste without the need for manual point-by-point cleaning. Staff only need to clean the recycling tank regularly, which greatly reduces the intensity of manual labor and reduces the frequency and time cost of manual cleaning. The design of the detachable splicing plate can be adapted to impellers of different lengths, fill the gap between the recycled parts and the moving clamp, avoid waste leakage, further improve the recycling rate, reduce waste, lower the cost of subsequent waste treatment, and achieve the dual benefits of environmental protection and high efficiency.

[0017] (3) The intelligent dynamic balancing calibration platform for snow blower impellers described in this invention uses a protective shell to enclose the core working components, effectively isolating dangerous operating areas such as impeller rotation and machining calibration, preventing workers from contacting the high-speed rotating impeller and splashing waste, and reducing safety hazards; the electric door on the top of the protective shell facilitates the loading and unloading of the impeller, and the design of the ventilation opening ensures air circulation inside the protective shell, avoiding problems such as air pressure difference and turbulent flow caused by the closed environment, preventing additional vibration of the test components, and ensuring the stability and accuracy of equipment operation. The observation window on the side of the protective shell allows workers to observe the equipment operation status, the testing and calibration process, and the waste recycling status in real time, enabling timely detection and handling of equipment faults, reducing fault diagnosis and maintenance costs. The structure of each component of the equipment is compact and reasonable, with reliable connections. The elastic element can buffer the vibration of the recycled component, the bellows can adapt to the displacement of the recycled component and ensure airflow sealing, and the sealed bearing can reduce the wear of the disc plate rotation. These designs all extend the service life of the components, reduce equipment wear and maintenance frequency, and at the same time, the equipment is fully automated, easy to operate, and does not require complicated debugging and operation procedures, further reducing the operating and maintenance costs of the equipment.

[0035] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example: Figures 1-15 As shown, the present invention discloses an intelligent dynamic balancing calibration platform for a snowplow impeller, comprising a testing assembly and a testing component 2 disposed on its inner side. The testing assembly includes a fixed clamp 16 and a movable clamp 17, which are respectively clamped at both ends of the testing component 2. A base 13 is fixed to the bottom of the fixed clamp 16, and the movable clamp 17 is slidably connected to the inner side of the base 13. A driving component 14 is disposed on the inner side of the base 13. A protective shell 3 is fixed to the top of the base 13, and a hollow frame 15 is fixed to the inner side of the protective shell 3. A controller 11 is fixed to one side of the base 13, and a power box 12 is fixed to the top of the end of the base 13 near the controller 11. The output end of the power box 12 is fixedly connected to one end of the testing component 2.

[0037] In this embodiment, the core of the snow blower impeller dynamic balance test is the coordinated operation of three major components: the controller 11, the power box 12, and the clamps. This precise identification of impeller mass eccentricity defects provides a scientific basis for subsequent weight reduction calibration and ensures the stability of the impeller during high-speed rotation. Each component has its own function and is indispensable. Their principles and functions revolve around the high-speed operating characteristics of the impeller. The moving clamp 17 and the fixed clamp 16, as the core components for clamping the test piece 2 (impeller), primarily function to achieve precise positioning and secure clamping of the impeller. By adapting the clamping method to the impeller structure, they ensure that the clamping reference of the test piece 2 is consistent with the snow blower's mounting reference. At the same time, they ensure that the coaxiality between the test piece 2 and the output shaft of the power box 12 is ≤0.01mm, avoiding test distortion caused by clamping deviations. They can also resist the centrifugal force during impeller rotation and the slight vibrations during subsequent testing, preventing the impeller from loosening or shifting, and providing a stable foundation for the test. The core function of the power box 12 is to provide stable power for the impeller rotation. Based on the actual working speed of the snow blower impeller (1000-3000 r / min), it drives the impeller to rotate at a uniform high speed, simulating its actual working conditions. This causes the impeller to generate unbalanced forces due to mass eccentricity caused by uneven material, irregular structure, and processing deviations, thus inducing slight vibrations in the equipment. This provides core working condition support for the controller 11 to collect detection data. As the "control and analysis core" of the detection system, the controller 11 receives the speed signal from the power box 12 and the vibration data fed back by the vibration sensor in real time. Through built-in algorithm processing and analysis, it accurately calculates the weight and phase angle of the impeller imbalance, clarifies the specific location and volume of the impeller that needs to be de-weighted, and simultaneously controls the speed adjustment and start / stop of the power box 12, and coordinates the locking and unlocking of the clamps to ensure the automation and accuracy of the detection process and avoid human error. The three components work together to achieve the core function of dynamic balancing testing: accurately identifying impeller imbalance defects, providing precise parameters for subsequent milling and weight removal, avoiding severe vibration and noise caused by unbalanced forces during high-speed impeller rotation, preventing impeller cracking and detachment, ensuring the stability and safety of the snow blower, extending the service life of the impeller and snow blower equipment, and providing efficient and standardized testing support for batch impeller calibration, ensuring that each calibrated impeller meets the precision requirements for industrial use, and avoiding equipment failures caused by impeller imbalance. This is existing technology and will not be elaborated on here.

[0038] Specifically, a protective shell 3 is provided on the outer side of the detection assembly, a transverse movement part 4 is provided on one side of the detection component 2, a processing part 5 is provided at the output end of the transverse movement part 4, a feed adjustment part is provided at the end of the processing part 5 away from the detection component 2, a recovery part 6 is provided on the inner side of the detection assembly, an air hole 7 is provided on the top of the recovery part 6, a negative pressure device 9 is provided at the bottom of the transverse movement part 4, a duct 8 is connected between the negative pressure device 9 and the air hole 7, and a butterfly plate 10 is rotatably connected to the inner side of the duct 8; the duct 8, by utilizing the negative pressure generated by the negative pressure device 9 and directional guidance through the air hole 7, draws away the air near the detection component 2, applying external pressure to the waste material processed by the processing part 5. The force changes its movement trajectory and falls to the top of the recycling part 6; the feed adjustment part includes a telescopic member 52 set on one side of the processing part 5, the bottom of the processing part 5 is connected to a lifting plate 57, and the other end of the lifting plate 57 is connected to a driven wheel 59. The telescopic member 52 pushes the processing part 5 to process the detection part 2 while driving the lifting plate 57 to move down. The lifting plate 57 drives the driven wheel 59 to reverse so that the butterfly plate 10 rotates to reduce its proportion in the cross section of the air duct part 8, and increases the airflow channel area of ​​the air duct part 8. As the processing depth of the processing part 5 increases and the size of the waste increases, the suction capacity of the negative pressure device 9 and the air duct part 8 for the waste is enhanced.

[0039] In this embodiment, the negative pressure device 9 is turned on before processing. The negative pressure device 9 generates negative pressure to draw air from the inside of the protective shell 3. The air enters the air chamber 81 through the protective shell 3 and the air hole 7, and then enters the negative pressure device 9 through the main pipe 82 and the regulating pipe 83 before being discharged. During the air flow, since the air hole 7 is arranged in a circumferential array and is distributed in multiple groups, it can fully cover the detection piece 2 and its surrounding space, so that the air flows evenly and avoids local air pressure differences. At the same time, when the processing unit 5 starts to process the detection piece 2, the waste generated changes its movement trajectory under the negative pressure generated by the negative pressure device 9 and the directional guidance of the air hole 7. The waste is carried by the air and falls to the top of the recovery piece 6 along the airflow direction, avoiding the splashing of processing waste such as cutting waste, milling waste or welding waste that could damage other equipment or pollute the environment.

[0040] Specifically, the feed adjustment unit also includes a base 51, which is slidably engaged with the inner side of the transverse frame 43. The machining unit 5 is fixed to the top of the bottom wall of the base 51. The output axis of the machining unit 5 is on the same horizontal plane as the axis of the detection piece 2. A toothed plate 53 is fixed to the bottom of the base 51. A bottom gear 54 is rotatably connected to the bottom of the transverse frame 43. The bottom gear 54 meshes with the toothed plate 53. A transmission rod 55 is slidably engaged with the inner side of the bottom gear 54. Two limit frames 571 are fixed to one side of the bracket 41. The two ends of the transmission rod 55 are rotatably connected to the inner side of the two limit frames 571. Side gears 56 are fixed to both ends of the transmission rod 55. Two lifting plates 57 are slidably connected to the inner side of the two limit frames 571 respectively. The two lifting plates 57 mesh with the two side gears 56 respectively. Two side plates 58 are fixedly connected to the bottom ends of the two lifting plates 57 through connecting parts. The inner side of the duct 8 is provided with teeth. The two side plates 58 are slidably snapped to the top of the base 13 through the connecting parts. The butterfly plate 10 is rotatably connected to the inner side of the regulating pipe 83 through the sealed bearing. The two driven wheels 59 are fixed to the two ends of the butterfly plate 10 respectively. The two driven wheels 59 are respectively engaged with the two side plates 58. The duct section 8 includes an air chamber 81, a main pipe 82 and a regulating pipe 83. The air chamber 81 is fixed to the bottom of the recovery component 6 through a corrugated pipe. The corrugated pipe is used to ensure that the air chamber 81 and the air hole 7 are connected when the recovery component 6 vibrates. The main pipe 82 is fixedly connected to the bottom of the air chamber 81. The other end of the main pipe 82 is fixed with the regulating pipe 83. The other end of the regulating pipe 83 is fixedly connected to the output end of the negative pressure device 9. The negative pressure device 9 is fixed to the top of the base 13 through the connecting parts. There are multiple sets of air holes 7. Each set of air holes 7 is arranged in a circumferential array to ensure that the airflow covers the detection component 2 and its surrounding space.

[0041] In this embodiment, the operator controls the telescopic component 52 (which can be a cylinder, a hydraulic cylinder, or other device capable of providing radial telescopic force) to extend. The telescopic component 52 drives the base 51, which is fixedly connected to its output end, to move along the inner side of the transverse frame 43. The base 51 drives the processing part 5, which is fixed to the inner side, to move towards the side closer to the detection component 2. The processing part 5 processes the detection component 2.

[0042] During the feeding process, the base 51 drives the toothed plate 53 at its bottom to move synchronously. The toothed plate 53 drives the bottom gear 54 to rotate forward through meshing. The bottom gear 54 drives the side gear 56 to rotate forward through the transmission rod 55. The side gear 56 drives the lifting plate 57 to move closer to the base 13 through meshing. The lifting plate 57 drives the side plate 58 to move closer to the base 13. The side plate 58 drives the driven wheel 59 to rotate forward through meshing. The driven wheel 59 drives the butterfly plate 10 to rotate forward. The butterfly plate 10 gradually changes from inclined to horizontal. As the telescopic member 52 extends, the proportion of the butterfly plate 10 in the cross-section of the duct section 8 is reduced, and the airflow channel area of ​​the duct section 8 is increased. As the processing depth of the processing section 5 increases and the size of the waste increases, the suction capacity of the negative pressure device 9 and the duct section 8 for the waste is enhanced. As the processing of the processing section 5 proceeds, the feed adjustment section begins to play its role. While the telescopic component 52 pushes the processing section 5 to process the inspection piece 2, it also drives the lifting plate 57 to move downward. The lifting plate 57 drives the driven wheel 59 to reverse, causing the butterfly plate 10 to rotate. The rotation of the butterfly plate 10 reduces its proportion in the cross-section of the duct section 8, thereby increasing the airflow channel area of ​​the duct section 8. Thus, as the processing depth of the processing section 5 increases and the size of the waste increases, the suction capacity of the negative pressure device 9 and the duct section 8 for the waste also increases, ensuring that the waste can be smoothly sucked to the recovery piece 6, ensuring a clean processing environment, and avoiding interference from the waste in the processing process. This improves the working efficiency and processing quality of the entire snow blower impeller dynamic balancing intelligent calibration platform.

[0043] The staff can set up one or more transverse frames 43, and each transverse frame 43 has a different processing part 5 inside. The processing part 5 can be set as a milling fixture, a cutting fixture or a counterweight welding fixture, etc. (these are all existing technologies and will not be described in detail here) to process the test piece 2.

[0044] Specifically, the driving component 14 includes a threaded rod 142 and a first motor 141. The threaded rod 142 is rotatably connected to the inner side of the base plate 421, and the first motor 141 is fixed to the inner side of the base plate 421. One end of the threaded rod 142 is fixedly connected to the output end of the first motor 141, and the movable clamp 17 is engaged with the outer side of the threaded rod 142.

[0045] In this embodiment, after processing is completed, the telescopic component 52 is controlled to retract so that the processing part 5 returns to its original position. Then, the processed test piece 2 is tested again. If the test is qualified, the controller 11 opens the moving end of the electric door 31. Then, the test piece 2 is clamped and hoisted with the lifting equipment. After the clamping of the test piece 2 by the fixed clamp 16 and the moving clamp 17 is released, the test piece 2 is clamped by the lifting equipment. The first motor 141 is controlled to reverse. The first motor 141 drives the threaded rod 142 to reverse. The threaded rod 142 drives the moving clamp 17 to move away from the fixed clamp 16 through the meshing action. When the moving clamp 17 is completely separated from the test piece 2 and it is ensured that no collision will occur in the future, the operator controls the lifting equipment to move the test piece 2 from the inside of the fixed clamp 16 and then from the inside of the protective shell 3 to complete the unloading.

[0046] If the test fails, test piece 2 will be processed again and tested again. If it passes the test, it will be unloaded.

[0047] Specifically, the transverse movement part 4 includes a bracket 41, which is fixed to the top of the base 13. The bracket 41 is located on one side of the detection piece 2. A drive part 42 is installed on the side of the bracket 41 near the detection piece 2. The output end of the drive part 42 is connected to a transverse movement frame 43. The drive part 42 includes a base plate 421, which is detachably connected to one side of the bracket 41. A second motor 422 is fixed inside the base plate 421. The output end of the second motor 422 is connected to a lead screw 423 through a reducer. The transverse movement frame 43 is threaded to the outside of the lead screw 423.

[0048] In this embodiment, after the inspection is completed, the operator uses the controller 11 to rotate the position of the test piece 2 that needs to be processed to the side closer to the bracket 41 via the power box 12, and ensures that the position that needs to be processed is on the horizontal plane where the center line of the processing part 5 and the test piece 2 are located. Then, the operator controls the second motor 422 to rotate, and the second motor 422 drives the lead screw 423 to rotate. The lead screw 423 drives the transverse frame 43 to move along the inner side of the base plate 421 through meshing, thereby driving the processing part 5 inside it to move, so that the processing part 5 is horizontally aligned with the position of the test piece 2 that needs to be processed, in preparation for the processing part 5 to feed and process.

[0049] Specifically, the recycling component 6 is slidably snapped onto the top of the hollow frame 15. An elastic component 63 is fixed to the top of the hollow frame 15. The top of the elastic component 63 is fixedly connected to the bottom of the recycling component 6. The top of the recycling component 6 is designed to be inclined. A recycling groove 61 is opened at the bottom of the top of the recycling component 6. A splicing plate 62 is detachably connected to the inner side of the recycling component 6.

[0050] In this embodiment, the elastic element 63 can be set as a spring or other elastic device. After the processing waste falls to the top of the recycling element 6, it will disrupt the balance provided by the negative pressure and the elastic element 63 in the recycling element 6. Due to the different mass and falling point of the processing waste, the recycling element 6 vibrates under the action of the elastic element 63. During the vibration, the processing waste moves towards the recycling tank 61 under the action of the inclined surface of the recycling element 6, thereby completing the recycling of the processing waste. The staff only needs to clean the casing of the recycling tank 61 regularly. The splicing plate 62 is used to fill the gap between the recycling element 6 and the moving clamp 17 or to provide the moving space of the moving clamp 17 when testing and calibrating impellers of different lengths, improving practicality while ensuring that the processing waste is recycled to the inside of the recycling tank 61.

[0051] Specifically, an electric door 31 is installed through the top of the protective shell 3, and a ventilation opening is provided through the moving end of the electric door 31. Observation windows 32 are installed through the side of the protective shell 3 away from the controller 11 and the two sides adjacent to it. The observation windows 32 can also be provided through the ventilation openings to avoid the risk of vibration of the detection element 2 caused by air pressure difference or turbulent eddies generated near the detection element 2.

[0052] In this embodiment, the electric door 31 facilitates the placement of the test piece 2 inside the protective shell 3 for testing, and also facilitates its removal after testing. The ventilation openings ensure airflow within the protective shell 3, preventing pressure differences or turbulent flow from affecting the test piece 2. The observation window 32 allows for real-time monitoring of the testing inside the protective shell 3, enabling timely detection and handling of problems. The ventilation openings on the observation window 32 also serve the same purpose as those on the electric door 31, ensuring airflow within the protective shell 3 and guaranteeing the accuracy and stability of the testing. Furthermore, the entire snowplow impeller dynamic balancing intelligent calibration platform is compact and rationally designed, with efficient and stable collaboration between components, significantly improving the efficiency and accuracy of impeller dynamic balancing testing and providing strong support for the stable operation of the snowplow.

[0053] Working principle: Initial state as follows Figures 1-15As shown, after the inspection, the operator controls the controller 11 to rotate the position of the test piece 2 to be processed closer to the support 41 via the power box 12, ensuring that this position is on the horizontal plane where the center line of the processing section 5 and the test piece 2 are located. Then, the operator controls the second motor 422 to rotate, driving the lead screw 423 to move the transverse frame 43 along the inner side of the base plate 421, so that the processing section 5 is horizontally aligned with the position of the test piece 2 to be processed, preparing for processing. Before processing, the negative pressure device 9 is turned on, which creates negative pressure to suck the air in the protective shell 3. The air is discharged through the protective shell 3, air holes 7, air chamber 81, main pipe 82 and regulating pipe 83. The air holes 7 are distributed in a circumferential array to make the air flow uniformly and avoid local air pressure differences. During processing, the waste material is guided by the negative pressure and air holes 7 to fall along the airflow to the top of the recovery piece 6. When the waste material falls to the top of the recovery piece 6, it disrupts its balance and causes it to vibrate under the action of the elastic element 63. The waste material moves towards the recovery tank 61 under the action of the inclined plane, completing the recovery. The operator cleans the recovery tank 61 regularly.

[0054] The operator controls the extension of the telescopic component 52, which moves the base 51 along the inner side of the transverse frame 43, bringing the processing section 5 closer to the test piece 2 for processing. During feeding, the base 51 moves the toothed plate 53, and through a series of transmissions, the butterfly plate 10 changes from inclined to horizontal, increasing the airflow channel area of ​​the duct section 8 and enhancing the suction capacity of the negative pressure device 9 and the duct section 8 for waste materials. After processing, the operator controls the extension of the telescopic component 52 to retract, resetting the processing section 5. The test is then performed again. If it passes, the controller 11 opens the moving end of the electric door 31, and the lifting equipment clamps and lifts the test piece 2. The clamp is released, and the first motor 141 is controlled to reverse, moving the moving clamp 17 away from the test piece 2. Finally, the lifting equipment removes the test piece 2. If it fails, the process and test are repeated. If it passes, the material is unloaded.
