[0001] This invention relates to the field of beryllium copper alloy surface grinding technology, specifically to a beryllium copper alloy surface treatment device and its usage method. Background Technology

[0002] Surface treatment of beryllium copper alloys is a process that artificially forms a layer on the surface of beryllium copper alloy materials with different mechanical, physical, and chemical properties from those of beryllium copper alloys. The purpose of surface treatment is to meet the special functional requirements of corrosion resistance, wear resistance, and decoration of products. For metal castings, commonly used surface treatment methods include mechanical grinding, chemical treatment, surface heat treatment, and spraying surface treatment processes.

[0003] The existing beryllium copper alloy surface treatment equipment has the following drawbacks:

However, the device in the above document has technical problems such as separating the rough grinding, fine grinding, polishing and detection units, requiring manual intervention or workpiece transfer between each process, resulting in low production efficiency, insufficient automation, and lack of intelligent feedback closed loop based on real-time detection, making it impossible to dynamically adjust parameters and ensuring high consistency and yield. Summary of the Invention

[0005] The purpose of this invention is to provide a beryllium copper alloy surface treatment device and its usage method to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a beryllium copper alloy surface treatment device, comprising a base, a rotating support table mounted on the top of the base via a bearing, a clamping assembly provided on the top of the rotating support table for clamping and fixing the beryllium copper alloy workpiece, and a rotation drive assembly provided outside the rotating support table for driving the rotating support table to rotate.

[0007] The base is provided with support plates at the four corners of the top, and a top plate is provided on the top of the support plates. The bottom of the top plate is arranged with a rough grinding unit, a fine grinding unit, a polishing unit and an in-situ detection unit in sequence along the workpiece rotation axis.

[0008] The coarse grinding unit, fine grinding unit, and polishing unit are electrically connected to the constant force feed control module via cables.

[0009] The in-situ detection unit feeds back real-time data to the control cabinet via a cable, and the control cabinet adaptively adjusts the processing parameters of the rough grinding unit, fine grinding unit, and polishing unit based on the feedback data.

[0010] Preferably, the constant force feed control module includes several hydraulic telescopic cylinders fixedly connected to the bottom of the top plate, and the output ends of the hydraulic telescopic cylinders are respectively connected to the top of the rough grinding unit, the fine grinding unit, and the polishing unit through a radial moving mechanism. A pressure sensor for real-time detection of processing pressure is provided at the connection between the output end of the hydraulic telescopic cylinder and the radial moving mechanism. The radial moving mechanism includes a linear guide rail fixedly connected to the output end of the hydraulic telescopic cylinder. A third servo motor is provided at one end of the linear guide rail. A second threaded rod is provided at the output end of the third servo motor. A slider is threadedly connected to the second threaded rod, and the slider moves radially along the linear guide rail. The bottom of the slider is respectively connected to the top of the rough grinding unit, the fine grinding unit, and the polishing unit.

[0011] Preferably, the clamping assembly includes several radially extending through slots opened on the top of the rotating platform. A first servo motor is fitted into the inner wall of each through slot. The output end of the first servo motor is connected to a first threaded rod arranged along the direction of the through slot. A clamping block is threadedly connected to the outer wall of the first threaded rod, and the bottom of the outer wall of the clamping block is movably connected to the inner wall of the through slot. A clamping pad is provided on the side of the clamping block facing the beryllium copper alloy workpiece.

[0012] Preferably, the rotary drive assembly includes a second servo motor fitted on one side of the top of the base. The output shaft of the second servo motor is equipped with a transmission gear. A brake is also fitted on the output shaft of the second servo motor and is fixed to the top of the base by a bracket. The outer wall of the transmission gear is meshed with a driven gear, and the inner wall of the driven gear is fixedly fitted on the outer circumferential wall of the rotating platform.

[0013] Preferably, a coolant tank is provided on one side of the back of the base, and a vacuum cleaner is provided on the other side. The coolant tank stores a rust-preventive water-based coolant with a pH value of 8.5-9.5, and the rust-preventive water-based coolant contains benzotriazole as a copper alloy corrosion inhibitor. A water pump is provided on the top of the coolant tank, and a delivery hose is installed at the output end of the water pump. A nozzle is provided on the outer wall of the other end of the delivery hose, penetrating the edge of the top plate, and the nozzle is located at the bottom edge of the top plate.

[0014] Preferably, the vacuum cleaner has a vacuum hose at its suction port, and the other end of the vacuum hose passes through the middle of the top of the top plate and is equipped with a suction nozzle, which is located in the middle of the bottom of the top plate.

[0015] Preferably, the control cabinet is electrically connected to the water pump and the vacuum cleaner, and is configured to synchronously control the coolant spraying and vacuuming operations according to the opening and closing states of the coarse grinding unit, the fine grinding unit, and the polishing unit.

[0016] Preferably, the in-situ detection unit includes a laser displacement sensor fixedly installed at the bottom of the top plate and a non-contact roughness measuring instrument based on laser scattering method. The laser displacement sensor measures the contour dimensions of the beryllium copper alloy workpiece in real time, and the non-contact roughness measuring instrument based on laser scattering method detects the surface roughness Ra value of the beryllium copper alloy workpiece. Both the laser displacement sensor and the non-contact roughness measuring instrument based on laser scattering method are connected to the control cabinet via data cables.

[0017] Preferably, the control cabinet is fixedly installed on the top of the top plate. The control cabinet integrates an industrial computer and a touch screen. The industrial computer has a built-in adaptive control algorithm, which is configured to: receive real-time data from the in-situ detection unit and compare it with the preset processing quality target value; when the detected deviation exceeds the tolerance range, automatically generate control commands to dynamically adjust the feed rate, rotation speed and processing time of the rough grinding unit, fine grinding unit or polishing unit.

[0018] Preferably, the working steps of the beryllium copper alloy surface treatment device are as follows:

[0019] S1. Place the beryllium copper alloy workpiece to be processed in the center of the rotating platform, start the clamping assembly, the control cabinet issues a command, the first servo motor works, drives the first threaded rod to rotate, and drives multiple clamping blocks to move synchronously along the through groove radially. The workpiece is firmly clamped in the center of the rotating platform by the clamping pad. The second servo motor in the rotation drive assembly starts, and through the meshing of the transmission gear and the driven gear, drives the entire rotating platform and the workpiece to rotate at the set initial speed. The brake ensures accurate positioning when the rotation stops.

[0020] S2. Set the processing parameters and start the automatic processing flow through the touch screen of the control cabinet. The control cabinet first activates the rough grinding unit and the constant force feed control module starts working: the hydraulic telescopic cylinder pushes the rough grinding unit down to near the workpiece surface, and then the third servo motor starts, driving the second threaded rod to rotate, so that the slider carries the rough grinding unit to feed radially towards the workpiece along the linear guide. The pressure sensor monitors the contact pressure between the grinding head and the workpiece surface in real time and feeds the data back to the control cabinet. The control cabinet dynamically adjusts the pressure of the hydraulic telescopic cylinder and the feed of the third servo motor through the closed-loop control algorithm to ensure that the force applied to the workpiece remains constant throughout the rough grinding process, and avoids pressure fluctuations that may cause overcutting or damage.

[0021] S3. When the rough grinding unit is working, the control cabinet synchronously controls the coolant system and dust removal system. The water pumps in the corresponding pipelines start, and the specially made anti-rust water-based coolant in the coolant tank is precisely sprayed to the processing area through the delivery hose and nozzle to cool the workpiece and grinding wheel, and to prevent the beryllium copper alloy from overheating and oxidizing or rusting. The vacuum cleaner starts and efficiently extracts the grinding debris and dust generated in the processing area through the vacuum hose and vacuum nozzle to keep the processing environment clean.

[0022] S4. During the rough grinding process or after a rough grinding cycle, the control cabinet can instruct the in-situ detection unit to perform non-contact measurement of the contour dimensions of the workpiece at the current stage through the laser displacement sensor. The non-contact roughness measuring instrument based on the laser scattering method quickly measures the current roughness Ra value of the workpiece surface, and the measurement data is transmitted to the industrial computer in the control cabinet in real time.

[0023] S5. The industrial computer compares the detected real-time data with the preset quality target value:

[0024] Rough grinding stage: If the inspection finds that the allowable material is still too large, the rough grinding unit is controlled to continue processing according to the parameters; if the size is close to the target, the feed rate is reduced or the process is moved to the next stage.

[0025] Fine grinding stage: After the rough grinding meets the standard, rotate the support table index to move the workpiece to the bottom of the fine grinding unit. The fine grinding unit starts working under constant force control. After processing, in-situ inspection is performed again. Based on the results, the fine grinding parameters are adaptively adjusted until the size and roughness meet the fine grinding requirements.

[0026] Polishing stage: After the fine grinding meets the standard, the workpiece is moved to the bottom of the polishing unit. The polishing unit performs the final polishing under constant force control. The in-situ detection unit monitors the final surface quality, and the control cabinet finely adjusts the polishing parameters according to the feedback to ensure that the preset high gloss requirements are met.

[0027] S6. When the in-situ detection unit confirms that the final size and surface roughness of the workpiece fully meet the preset standards, the control cabinet determines that the processing is complete, all processing units stop working and return to the initial position, the cooling and dust removal system stops, the rotary drive motor stops, the brake is activated to stop the rotating platform from rotating, the clamping components are released, and the operator removes the beryllium copper alloy workpiece that has completed surface treatment.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This invention integrates rough grinding, fine grinding, polishing and in-situ detection units, which helps to improve production efficiency and automation. The constant force feed control module ensures the stability and consistency of the processing process. Combined with the intelligent feedback closed loop formed by the in-situ detection unit, the system can adaptively optimize the processing parameters of each unit, thereby ensuring high precision, high consistency and ultra-high yield of workpiece surface treatment.

[0030] 2. This invention utilizes a constant force feed control module, employing a hydraulic telescopic cylinder to provide stable power, and a radial movement mechanism driven by a third servo motor to ensure the stability of the tool-workpiece surface contact during processing, thereby achieving extremely high processing consistency and surface forming quality. Furthermore, through an integrated non-contact in-situ detection unit, using a laser displacement sensor and a non-contact roughness measuring instrument, non-destructive real-time detection of the workpiece's dimensions, contours, and surface morphology is performed, and the data is fed back in real-time to the control cabinet with a built-in industrial computer and adaptive algorithm. By comparing with preset quality targets, it can intelligently make decisions and dynamically adjust the feed rate, rotation speed, and processing time of each unit, thereby significantly improving the level of intelligent processing and ensuring that every beryllium copper alloy workpiece achieves high precision and high consistency.

[0031] 3. This invention achieves automated clamping of workpieces of different sizes by using a first threaded rod precisely driven by a first servo motor to drive radially arranged clamping blocks to move synchronously. This not only greatly improves clamping efficiency and consistency, but also prevents damage to the surface of the workpiece by using a clamping pad. The rotary drive component drives the rotating platform to rotate via a gear set through a second servo motor, providing smooth rotational motion and ensuring stable linear speed during processing. The integrated brake provides a safety locking function when the equipment stops or is being tested, preventing the turntable from moving accidentally, thus ensuring high precision and safety throughout the entire processing process.

[0032] 4. This invention achieves a compact and efficient integrated layout by placing the coolant tank and the vacuum cleaner on opposite sides of the base. By using a special anti-rust coolant with a pH of 8.5-9.5 and the addition of benzotriazole corrosion inhibitor, it can not only effectively protect steel workpieces but also specifically prevent corrosion on copper alloy surfaces, significantly improving the quality and consistency of processed workpieces. Furthermore, through the control system, the grinding and polishing unit can automatically start and stop during operation, achieving efficient synchronization of cooling and dust removal. This not only removes dust at the source, improves the working environment, and protects personnel health and long-term equipment operation, but also achieves the goals of energy saving, consumption reduction, and simplified operation.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0044] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 An embodiment of the present invention provides a beryllium copper alloy surface treatment device, comprising a base 1, a rotating platform 2 mounted on the top of the base 1 via bearings, a clamping assembly on the top of the rotating platform 2 for clamping and fixing the beryllium copper alloy workpiece, a rotation drive assembly outside the rotating platform 2 for driving the rotating platform 2 to rotate, support plates 3 at the four corners of the top of the base 1, a top plate 4 on the top of the support plates 3, and a rough grinding unit 5, a fine grinding unit 6, a polishing unit 7 and an in-situ detection unit 8 arranged sequentially along the workpiece rotation axis at the bottom of the top plate 4, the rough grinding unit 5, the fine grinding unit 6 and the polishing unit 7 being electrically connected to a constant force feed control module via cables, the in-situ detection unit 8 feeding back real-time data to a control cabinet 10 via cables, and the control cabinet 10 adaptively adjusting the processing parameters of the rough grinding unit 5, the fine grinding unit 6 and the polishing unit 7 based on the feedback data;

[0045] Furthermore, by integrating rough grinding, fine grinding, polishing, and even inspection into one device, all processes can be completed sequentially by rotating the tray 2 after the workpiece is clamped. This greatly reduces the time spent on multiple clamping and transfer in traditional processes. The rotary drive component drives the workpiece to rotate to different workstations, thereby automating the production process, reducing manual intervention, and improving work efficiency.

[0046] By setting the constant force feed control module, the pressure of the grinding and polishing tool on the workpiece remains constant regardless of the surface undulations. This helps to avoid over-grinding, under-grinding, or surface scratches caused by pressure fluctuations, thereby ensuring the consistency and extremely high repeatability of the entire surface treatment.

[0047] Through the in-place detection unit 8, the surface quality of the workpiece can be measured in real time and the data can be fed back to the control cabinet 10. Based on the real-time detection data, the control cabinet 10 can adaptively adjust the processing parameters of the previous process. When the roughness of a certain area is not up to standard, the system can automatically instruct the polishing unit 7 to perform secondary processing or adjust the parameters of that area, ensuring that the quality of each product can reach the optimal standard, thereby achieving intelligent processing effect.

[0048] Taking into account the characteristics of beryllium copper alloy, a staged processing method is adopted, and the process path is scientific and reasonable. It can effectively obtain ideal smoothness and surface integrity. At the same time, through automated processing and intelligent adjustment, the influence of the operator's technical level and experience on product quality is minimized, ensuring the stability, reliability and high yield of product quality in mass production.

[0049] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 An embodiment of the present invention provides a beryllium copper alloy surface treatment device. The constant force feed control module includes several hydraulic telescopic cylinders 11 fixedly connected to the bottom of a top plate 4. The output ends of the hydraulic telescopic cylinders 11 are respectively connected to the tops of a rough grinding unit 5, a fine grinding unit 6, and a polishing unit 7 via radial movement mechanisms. A pressure sensor 12 for real-time detection of processing pressure is provided at the connection between the output end of the hydraulic telescopic cylinder 11 and the radial movement mechanism. The radial movement mechanism includes a linear guide rail 35 fixedly connected to the output end of the hydraulic telescopic cylinders 11. A third servo motor 36 is provided at one end of the linear guide rail 35. A second threaded rod 37 is provided at the output end of the third servo motor 36. A slider 38 is threadedly connected to the second threaded rod 37, and the slider 38 moves radially along the linear guide rail 35. The bottom of the slider 38 is respectively connected to the tops of the rough grinding unit 5, the fine grinding unit 6, and the polishing unit 7. The in-situ detection unit 8 includes a fixed... A laser displacement sensor 31 and a non-contact roughness measuring instrument 32 based on laser scattering method are installed at the bottom of the top plate 4. The laser displacement sensor 31 measures the contour dimensions of the beryllium copper alloy workpiece in real time, and the non-contact roughness measuring instrument 32 based on laser scattering method detects the surface roughness Ra value of the beryllium copper alloy workpiece. Both the laser displacement sensor 31 and the non-contact roughness measuring instrument 32 based on laser scattering method are connected to the control cabinet 10 via data cable. The control cabinet 10 is fixedly installed on the top of the top plate 4. The control cabinet 10 integrates an industrial computer 33 and a touch screen 34. The industrial computer 33 has a built-in adaptive control algorithm. The algorithm is configured to receive real-time data from the in-situ detection unit 8 and compare it with the preset processing quality target value. When the deviation is detected to exceed the tolerance range, the control command is automatically generated to dynamically adjust the feed rate, rotation speed and processing time of the rough grinding unit 5, fine grinding unit 6 or polishing unit 7.

[0050] Furthermore, the hydraulic telescopic cylinder 11 can provide a huge, stable and highly anti-interference output force, providing a scenario with large and constant pressure for the coarse grinding and fine grinding stages, thereby ensuring a stable material removal rate;

[0051] The radial movement mechanism composed of the third servo motor 36 and the second threaded rod 37 can precisely adjust the position of the processing unit. Furthermore, it can cooperate with the pressure sensor 12 for position compensation in constant force control. The pressure sensor 12 monitors the pressure data in real time to ensure that the processing force is completely consistent with the set value, thereby avoiding workpiece deformation or equipment vibration interference, and thus obtaining extremely high surface forming consistency.

[0052] The in-situ detection unit 8 integrates a laser displacement sensor 31 and a non-contact roughness measuring instrument 32 based on laser scattering. The laser displacement sensor 31 monitors the contour dimensions and macroscopic shape errors of the workpiece in real time, while the non-contact roughness measuring instrument 32 quantitatively detects the microscopic morphology of the surface, thereby realizing a comprehensive and digital evaluation of the workpiece surface quality. At the same time, the non-contact roughness measuring instrument 32 can avoid scratching or contaminating the finished precision surface by the measuring head, realizing non-destructive testing. All test results are uploaded in real time in the form of data, providing an accurate data foundation for process control and product quality traceability.

[0053] The control cabinet 10 integrates an industrial computer 33 and an adaptive control algorithm. The built-in algorithm can perform complex calculations and judgments based on real-time detection data. It can not only determine whether the result is qualified or unqualified, but also intelligently generate optimization instructions. If the Ra value is still too large after fine grinding, the algorithm will decide to extend the fine grinding time or increase the feed of the polishing unit 7. When the size is close to the lower limit, the processing will be terminated in advance.

[0054] The touchscreen 34 provides operators with an intuitive interface for parameter setting, status monitoring, and data analysis, greatly reducing the technical threshold for equipment operation and process debugging.

[0055] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of the present invention provides a beryllium copper alloy surface treatment device. The clamping assembly includes a plurality of radially extending through slots 13 opened on the top of the rotating support 2. A first servo motor 14 is fitted into the inner wall of each through slot 13. The output end of the first servo motor 14 is connected to a first threaded rod 15 arranged along the direction of the through slot 13. A clamping block 16 is threadedly connected to the outer wall of the first threaded rod 15. The bottom of the outer wall of the clamping block 16 is movably connected to the inner wall of the through slot 13. A clamping pad 17 is provided on the side of the clamping block 16 facing the beryllium copper alloy workpiece. The rotation drive assembly includes a second servo motor 18 fitted into one side of the top of the base 1. A transmission gear 19 is installed on the output shaft of the second servo motor 18. A brake 20 is also fitted on the output shaft of the second servo motor 18. The brake 20 is fixed to the top of the base 1 by a bracket. A driven gear 21 is meshed with the outer wall of the transmission gear 19. The inner wall of the driven gear 21 is fixedly sleeved on the outer circumferential wall of the rotating support 2.

[0056] Furthermore, by using the first servo motor 14 to drive the first threaded rod 15 to control the movement of the clamping block 16, precise numerical control and automated control of the clamping force are achieved. This helps to avoid the uncontrollability of traditional manual clamping, ensuring the consistency and reliability of clamping each workpiece. At the same time, multiple radially arranged clamping units can be controlled independently or synchronously, which can flexibly adapt to beryllium copper alloy workpieces of different diameters and shapes. It has strong versatility, does not require changing the fixture, and improves the production flexibility of the equipment. The clamping pad 17 set on the clamping block 16 effectively prevents scratches, indentations or other mechanical damage to the surface of the beryllium copper alloy workpiece during the clamping process.

[0057] The movable connection between the bottom of the clamping block 16 and the inner wall of the through groove 13 ensures that the clamping block 16 will not rotate or shift during radial movement, providing extremely high clamping rigidity and stability, and ensuring that the workpiece will not loosen under high-speed rotation and processing force.

[0058] By using the second servo motor 18 as a power source to drive the transmission gear 19 to rotate the meshing passive gear 21, this gear transmission method can provide high torque, high efficiency and smooth rotational motion, with strong load-bearing capacity, suitable for continuous processing conditions. In addition, with the setting of the brake 20, it can quickly lock when the second servo motor 18 is powered off, preventing it from continuing to rotate due to inertia or moving accidentally due to external processing forces. This not only ensures safety when the machine stops, but also ensures that the rotating platform 2 can be firmly fixed in its original position when precise positioning is required, ensuring the accuracy of the detection data.

[0059] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5One embodiment of the present invention provides a beryllium copper alloy surface treatment device. A coolant tank 22 is provided on one side of the back of a base 1, and a vacuum cleaner 23 is provided on the other side. The coolant tank 22 stores a rust-preventive water-based coolant with a pH value of 8.5-9.5, and benzotriazole is added to the composition of the rust-preventive water-based coolant as a copper alloy corrosion inhibitor. A water pump 24 is provided on the top of the coolant tank 22, and a delivery hose 25 is installed at the output end of the water pump 24. The outer wall of the other end of the delivery hose 25... A nozzle 26 is provided through the edge of the top of the top plate 4, and the nozzle 26 is located at the edge of the bottom of the top plate 4. The vacuum cleaner 23 is provided with a vacuum hose 28 at its suction port. The other end of the vacuum hose 28 is provided with a vacuum nozzle 30 through the middle of the top of the top plate 4, and the vacuum nozzle 30 is located at the middle of the bottom of the top plate 4. The control cabinet 10 is electrically connected to the water pump 24 and the vacuum cleaner 23, and is configured to synchronously control the coolant spraying and vacuuming operation according to the opening and closing status of the coarse grinding unit 5, the fine grinding unit 6, and the polishing unit 7.

[0060] Furthermore, the cooling system and dust extraction system are placed on opposite sides of the base 1, resulting in a compact structure, high space utilization, avoidance of functional interference, and ease of maintenance. The coolant used is a weakly alkaline rust-preventive coolant with a pH value of 8.5-9.5, which can effectively neutralize acidic substances generated during processing and provide excellent rust protection for steel workpieces. The added benzotriazole acts as a copper alloy corrosion inhibitor, which can effectively inhibit the corrosion of copper workpieces or copper parts of equipment by the coolant, preventing surface discoloration or damage. It is suitable for machining centers with copper or copper alloy parts, ensuring the surface quality and precision of the workpieces.

[0061] The dust suction nozzle 30 is located in the center of the bottom of the top plate 4. It can suck up the generated dust and flying debris in the first time and prevent them from spreading, thereby reducing the concentration of inhalable particulate matter in the air, protecting the respiratory health of operators, and preventing dust from accumulating on key components such as precision guide rails, lead screws, and motors, reducing wear, extending the service life of equipment, and reducing the failure rate.

[0062] The control cabinet 10 automatically controls the water pump 24 and the vacuum cleaner 23 according to the opening and closing status of the processing unit, which can realize intelligent operation of starting when processing and stopping when stopping. There is no need for personnel to manually start and stop the cooling and vacuuming functions, reducing operation steps, avoiding the risk of human forgetfulness, thus avoiding unnecessary waste of energy and coolant, reducing operating costs, and improving environmental protection.

[0063] By positioning the nozzle 26 at the edge, the coolant can cover the processing area from the outside, forming an effective cooling and lubrication film.

[0064] Please see Figure 7 The present invention provides an embodiment of a beryllium copper alloy surface treatment device, the working steps of which are as follows:

[0065] S1. Place the beryllium copper alloy workpiece to be processed at the center of the rotating platform 2, start the clamping assembly, the control cabinet 10 issues a command, the first servo motor 14 works, drives the first threaded rod 15 to rotate, drives multiple clamping blocks 16 to move radially synchronously along the through groove 13, and the workpiece is firmly clamped in the center of the rotating platform 2 by the clamping pad 17. The second servo motor 18 in the rotation drive assembly starts, and drives the entire rotating platform 2 and the workpiece to rotate at the set initial speed through the meshing of the transmission gear 19 and the driven gear 21. The brake 20 ensures accurate positioning when the rotation stops.

[0066] S2. Set the processing parameters and start the automatic processing flow through the touch screen 34 of the control cabinet 10. The control cabinet 10 first activates the rough grinding unit 5, and the constant force feed control module starts to work: the hydraulic telescopic cylinder 11 pushes the rough grinding unit 5 down to near the workpiece surface, and then the third servo motor 36 starts, driving the second threaded rod 37 to rotate, so that the slider 38 carries the rough grinding unit 5 to feed radially towards the workpiece along the linear guide rail 35. The pressure sensor 12 monitors the contact pressure between the grinding head and the workpiece surface in real time and feeds the data back to the control cabinet 10. The control cabinet 10 dynamically adjusts the pressure of the hydraulic telescopic cylinder 11 and the feed of the third servo motor 36 through the closed-loop control algorithm to ensure that the force applied to the workpiece remains constant throughout the rough grinding process, and avoids pressure fluctuations that may cause overcutting or damage.

[0067] S3. When the rough grinding unit 5 is working, the control cabinet 10 synchronously controls the coolant system and the dust removal system. The water pump 24 of the corresponding pipeline is started, and the specially made anti-rust water-based coolant in the coolant tank 22 is precisely sprayed to the processing area through the delivery hose 25 and the nozzle 26 to cool the workpiece and the grinding wheel, and to prevent the beryllium copper alloy from overheating and oxidizing or rusting. The vacuum cleaner 23 is started, and the dust and debris generated in the processing area are efficiently extracted through the vacuum hose 28 and the vacuum nozzle 30 to keep the processing environment clean.

[0068] S4. During the rough grinding process or after a rough grinding cycle, the control cabinet 10 can instruct the in-situ detection unit 8 to perform non-contact measurement of the contour dimensions of the workpiece at the current stage through the laser displacement sensor 31, and the non-contact roughness measuring instrument 32 based on the laser scattering method to quickly measure the current roughness Ra value of the workpiece surface, and the measurement data is transmitted to the industrial computer 33 in the control cabinet 10 in real time.

[0069] S5, Industrial Computer 33 compares the detected real-time data with the preset quality target value:

[0070] Rough grinding stage: If the inspection finds that the allowable material is still too large, the rough grinding unit 5 is controlled to continue processing according to the parameters; if the size is close to the target, the feed rate is reduced or the process is moved to the next stage.

[0071] Fine grinding stage: After the rough grinding meets the standard, rotate the support table 2 to move the workpiece to the bottom of the fine grinding unit 6. The fine grinding unit 6 starts working under constant force control. After processing, in-situ inspection is performed again. Based on the results, the fine grinding parameters are adaptively adjusted until the size and roughness meet the fine grinding requirements.

[0072] Polishing stage: After fine grinding meets the standard, the workpiece is moved to the bottom of polishing unit 7. Polishing unit 7 performs final polishing under constant force control. In-situ detection unit 8 monitors the final surface quality. Control cabinet 10 finely adjusts polishing parameters according to feedback to ensure that the preset high gloss requirements are met.

[0073] S6. When the in-situ detection unit 8 confirms that the final size and surface roughness of the workpiece fully meet the preset standards, the control cabinet 10 determines that the processing is complete, all processing units stop working and return to the initial position, the cooling and dust removal system stops, the rotary drive motor stops, the brake 20 actuates to stop the rotating platform 2 from rotating, the clamping assembly is released, and the operator removes the beryllium copper alloy workpiece that has completed surface treatment.

[0074] The working principle, through the integration of rough grinding, fine grinding, polishing, and in-situ detection units 8, is conducive to improving production efficiency and automation. The constant force feed control module ensures the stability and consistency of the processing. Combined with the intelligent feedback closed loop formed by the in-situ detection units 8, the system can adaptively optimize the processing parameters of each unit, thereby ensuring high precision, high consistency, and ultra-high yield in workpiece surface treatment. Through the constant force feed control module, a hydraulic telescopic cylinder 11 provides stable power, and a radial movement mechanism driven by a third servo motor 36 ensures the stability of the tool-workpiece surface contact during processing, thus achieving extremely high processing consistency and surface forming quality. A laser displacement sensor 31 and a non-contact roughness measuring instrument 32 perform non-destructive real-time detection of the workpiece's dimensions, contours, and surface morphology, and feed the data back in real-time to a control cabinet 10 with a built-in industrial computer 33 and an adaptive algorithm. By comparing with preset quality targets, the instrument can intelligently make decisions and dynamically adjust the feed rate, speed, and processing time of each unit, thereby significantly improving the level of intelligent processing and ensuring that each beryllium copper alloy workpiece achieves high precision and high consistency. A first threaded rod 15, precisely driven by a first servo motor 14, drives the radially arranged clamping blocks 16 to move synchronously, achieving automated clamping of workpieces of different sizes, which not only greatly improves clamping efficiency. In terms of consistency, the clamping pad 17 further avoids damage to the surface of the workpiece being processed. The rotary drive assembly, driven by the second servo motor 18 via a gear set, rotates the rotating platform 2, providing smooth rotational motion and ensuring stable linear velocity during processing. The integrated brake 20 provides a safety locking function when the equipment stops or is being inspected, preventing accidental movement of the turntable and thus ensuring high precision and safety throughout the entire processing. By using a weakly alkaline anti-rust coolant with added benzotriazole corrosion inhibitor, oxidation or corrosion of the beryllium copper alloy workpiece is effectively prevented during processing, ensuring a clean and undamaged workpiece surface. The processing area is precisely cleaned by the water pump 24 and nozzles 26. Precise spraying provides excellent cooling and lubrication for the grinding and polishing process, preventing workpiece thermal deformation and surface burns. Controlled by a four-way valve 27 and a solenoid valve 29, dust nozzles 30 pointing towards each processing unit efficiently collect grinding debris and dust at the source of dust generation, keeping the equipment clean and preventing cross-contamination. All cooling and dust removal actions are intelligently linked and controlled by the control cabinet 10, synchronized with the start and stop of the processing units, achieving on-demand supply. This ensures optimal process results while achieving energy saving and consumption reduction. By placing the coolant tank 22 and the dust collector 23 on both sides of the base 1, a compact and efficient integrated layout is achieved. The pH value is 8.5-9.5. A specialized rust-preventive coolant with added benzotriazole corrosion inhibitor not only effectively protects steel workpieces but also specifically prevents corrosion on copper alloy surfaces, significantly improving the quality and consistency of processed workpieces. Furthermore, the control system automatically starts and stops the grinding and polishing unit during operation, achieving efficient synchronization of cooling and dust removal. This not only removes dust at the source, improving the working environment and ensuring personnel health and long-term equipment operation but also achieves energy conservation, consumption reduction, and simplified operation.
