[0002] Milling is a mechanical processing method that uses a milling cutter to process the surface of an object. The shell of medical equipment has extremely high requirements for processing accuracy, appearance flatness and structural consistency, which directly affects the assembly accuracy and safety of medical equipment.

[0003] Currently, most processing equipment has a simple clamping structure, which can only be adapted to workpieces of fixed size. It cannot meet the clamping needs of small and medium-sized conventional shells as well as large-span irregular shells. Its versatility is poor. Traditional mechanical positioning and clamping is not stable enough. During the milling process, workpiece displacement and micro-vibration are prone to occur, resulting in quality problems such as milling contour deviation and edge warping. Summary of the Invention

[0004] The purpose of this invention is to provide a precision milling machine for integral medical device housings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision milling machine for an integrated medical device housing, comprising a base plate and an internal frame. A servo motor three is disposed on one side of the base plate, and a bidirectional lead screw is installed at the output end of the servo motor three. A slide block is threaded on the outer surface of the bidirectional lead screw. The internal frame is fixedly disposed on the top of the slide block. A connecting frame is installed inside the internal frame, and a limiting component for equidistant adjustment and fixing is disposed inside the connecting frame. The limiting component includes a servo motor two, a slide rail, a connecting plate, a connecting plate, a slider, a connecting rod, and a positioning plate. A connecting plate is installed at the output end of the servo motor two, and a connecting plate is rotatably disposed at one end of the connecting plate. A slider is installed in the middle of the connecting plate, and a slide rail is disposed on the outside of the slider. A connecting rod is installed in the middle of the outer surface of the connecting plate, and a positioning plate is disposed at the end of the connecting rod.

[0006] Furthermore, there are five sets of connecting plates, sliders, connecting rods, and positioning plates, and the structures of the five sets of connecting plates, sliders, connecting rods, and positioning plates are completely identical.

[0007] Furthermore, the built-in frame is provided in two sets, and a top plate is installed on the top of the built-in frame.

[0008] Furthermore, a hydraulic rod is installed on the top of the top plate, and the output end of the hydraulic rod is fixedly connected to the connecting frame.

[0009] Furthermore, sliding rods are fixedly installed on both sides of the bottom of the top plate, and the outside of the sliding rods is slidably connected to both sides of the connecting frame.

[0010] Furthermore, a scraper is fixedly installed at the bottom of the built-in frame, and the scraper is slidably disposed on the surface of the base plate, and an opening is provided inside the base plate.

[0011] Furthermore, a milling frame is provided on the top of the base plate, and bases are symmetrically installed on both sides of the bottom of the base plate.

[0012] Furthermore, the milling frame is internally equipped with a milling assembly for milling, and the milling assembly includes a servo motor, a lead screw, a milling part, and a CCD camera. The output end of the servo motor is equipped with a lead screw, and the outer surface of the lead screw is provided with a milling part. The outer surface of the milling part is equipped with a CCD camera.

[0013] This invention provides a precision milling machine for integral medical device housings, which has the following advantages: 1. This invention constructs a dual-mode clamping and positioning structure by setting two sets of independent and interconnected built-in frames and matching limiting components. This effectively solves the problems of poor workpiece adaptability and insufficient clamping stability of traditional equipment. For conventional small and medium-sized medical equipment shells, a single set of built-in frames can be used for independent clamping and fixing, enabling rapid clamping and alternating feeding operations, thus improving batch processing efficiency. For large-sized, large-span, irregularly shaped medical equipment shells, two sets of built-in frames can be used for symmetrical clamping, forming a balanced constraint force from both ends of the workpiece, completely limiting the workpiece's offset and vibration degrees of freedom. Combined with multiple sets of equidistant telescopic positioning plates for multi-point contact positioning, the clamping firmness and positioning accuracy are greatly improved, ensuring the regularity and consistency of the milling process of medical equipment shells from a mechanical structure perspective.

[0014] 2. This invention, by setting a scraper at the bottom of the built-in frame and cooperating with the slots opened inside the base plate, can simultaneously and automatically scrape away the metal debris accumulated on the base plate table during the lateral movement of the built-in frame for processing. The debris falls and is collected automatically through the slots, preventing debris residue from accumulating and avoiding debris affecting the workpiece positioning accuracy and milling effect. Frequent manual cleaning is not required. At the same time, after the milling process is completed, the built-in frame can be automatically translated and reset by a servo motor with a three-drive bidirectional lead screw, realizing automated unloading operation and greatly reducing manual intervention.

[0017] 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 for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a precision milling machine for an integrated medical device housing includes a base plate 1, a milling frame 2, an internal frame 3, a scraper 4, a base 5, a milling assembly 6, a servo motor 601, a lead screw 602, a milled part 603, a CCD camera 604, a top plate 7, a hydraulic rod 8, a connecting frame 9, a limiting assembly 10, a servo motor 1001, a slide rail 1002, a connecting plate 1003, a connecting plate 1004, a slider 1005, a connecting rod 1006, a positioning plate 1007, a servo motor 11, a slide block 12, a bidirectional lead screw 13, a slot 14, and a slide rod 15. A servo motor 11 is located on one side of the base plate 1, and a bidirectional lead screw 13 is installed at the output end of the servo motor 11. The outer surface of the bidirectional lead screw 13 is threaded. With a slide block 12, after the workpiece is clamped, it is precisely transported to the milling area through horizontal and vertical dual-dimensional adjustment to match the machining stroke of the milling component 6. During vertical adjustment, the hydraulic rod 8 at the top of the top plate 7 is activated, and the output end of the hydraulic rod 8 drives the connecting frame 9 to rise and fall vertically as a whole. At the same time, the slide rods 15 on both sides of the bottom of the top plate 7 slide and cooperate with the sides of the connecting frame 9 to limit and guide the rising and falling movement of the connecting frame 9, ensuring that the connecting frame 9 and the workpiece clamped at the bottom move smoothly vertically, and precisely adjust the vertical machining distance between the workpiece and the milling component 6 to adapt to the milling needs of shells of different thicknesses. During horizontal adjustment, the servo motor 11 on the outside of the base plate 1 is activated, driving the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 drives the surface through thread transmission. The slide block 12 performs horizontal linear reciprocating motion. Since the built-in frame 3 is fixed to the top of the slide block 12, the slide block 12 can drive the built-in frame 3 and the clamped workpiece to move laterally when it moves, accurately adjusting the lateral machining position of the workpiece and achieving precise alignment between the workpiece and the milling tool. The built-in frame 3 is fixedly set on the top of the slide block 12. The top of the base plate 1 is provided with a milling frame 2, and the bottom sides of the base plate 1 are symmetrically installed with bases 5. The milling frame 2 is provided with a milling assembly 6 for milling. The milling assembly 6 includes a servo motor 601, a lead screw 602, a milling part 603, and a CCD camera 604. The output end of the servo motor 601 is equipped with a lead screw 602, and the outer surface of the lead screw 602 is provided with a milling part 603. A CCD camera 604 is mounted on the outer surface of milling machine 3. After the workpiece is adjusted to the designated machining position, the milling assembly 6 inside the milling frame 2 is activated to complete the precision milling operation on the medical device shell. During the milling operation, servo motor 601 drives the lead screw 602 to rotate. The lead screw 602 drives the milling workpiece 603 to make precise displacement along the axis of the lead screw 602 through thread transmission. Combined with the previous horizontal and vertical position adjustment of the workpiece, the milling workpiece 603 can achieve multi-directional and full-coverage milling movement to perform milling. At the same time, the CCD camera 604 mounted on the outside of the milling workpiece 603 works in real time throughout the process, performing high-definition visual acquisition of the workpiece milling position, machining contour, and milling allowance, and feeding back the machining data to the equipment control system in real time. The control system can then use the visual acquisition data to perform the milling.The system accurately identifies problems such as machining deviations, workpiece position offsets, and uneven milling allowances, and assists in real-time fine-tuning of the operating parameters of servo motor 601 to precisely correct the machining stroke and feed rate of the milled part 603, achieving visualized closed-loop precision machining. In addition, the equipment control system forms an electrical connection and linkage control with the hydraulic rod 8, which can intelligently adjust the extension and retraction stroke of the hydraulic rod 8 according to the workpiece thickness, milling depth, and real-time machining conditions. A connecting frame 9 is installed inside the built-in frame 3, and a limiting component 10 for equidistant adjustment and fixation is set inside the connecting frame 9. The limiting component 10 includes a servo motor 1001, a slide rail 1002, a connecting plate 1003, a connecting plate 1004, a slider 1005, a connecting rod 1006, and a positioning plate 1007. The output end of the servo motor 1001 is equipped with the connecting plate 1003, and one end of the connecting plate 1003 is rotatably connected to the connecting plate 1004. A slider 1005 is installed in the middle of the connecting plate 1004, and a slide rail 1002 is provided on the outside of the slider 1005. A connecting rod 1006 is installed in the middle of the outer surface of the connecting plate 1004, and a positioning plate 1007 is provided at the end of the connecting rod 1006. There are five sets of connecting plates 1004, sliders 1005, connecting rods 1006 and positioning plates 1007. The five sets of connecting plates 1004, sliders 1005, connecting rods 1006 and positioning plates 1007 have the same structure. During the clamping operation, the medical device shell workpiece to be processed is placed on the positioning station of the connecting frame 9, and then the servo motor 1001 of the limit component 10 is started. The servo motor 1001 outputs... The torque drives the connecting plate 1003 to rotate, which in turn drives multiple hinged connecting plates 1004 to move synchronously. Since the middle of the connecting plate 1004 slides against the slide rail 1002 via a slider 1005, the slide rail 1002 provides a limiting and guiding function for the slider 1005. This converts the rotational motion of the connecting plate 1003 into a smooth telescopic displacement of the connecting plate 1004. Five sets of identical connecting plates 1004, sliders 1005, connecting rods 1006, and positioning plates 1007 are configured. Driven by the servo motor 1001, the five positioning structures telescopically and equidistantly, extending from the outside of the workpiece via the positioning plate 1007 at the end of the connecting rod 1006. The system performs a clamping and bonding process to simultaneously position and fix multiple medical device housings. This limiting method can adaptively accommodate medical housing workpieces of different specifications, while ensuring uniform clamping spacing and firm fixation of each workpiece. This effectively prevents workpiece displacement and shaking during milling, guaranteeing the machining accuracy of precision milling from the source. Both sets of built-in frames 3 can independently cooperate with the limiting components 10 to complete workpiece clamping, forming two limiting and fixing modes: single-frame independent clamping and double-frame linkage clamping. This can be flexibly switched according to the size and specifications of the medical device housing, greatly expanding the equipment's processing adaptability. The specific limiting working principle is as follows: For conventional small and medium-sized medical device housings, a single set of built-in frames 3 is used for limiting and clamping. During operation, only one set of built-in frames 3 and its internal matching limiting components 10 are activated.One or more small outer shell workpieces are placed on the connecting frame 9. The connecting plate 1003 is driven to rotate by the servo motor 1001. With the guidance and limiting effect of the slide rail 1002 and the slider 1005, the five connecting plates 1004 and the connecting rod 1006 are extended synchronously and equidistantly. The end positioning plate 1007 is used to press and clamp the outer side of the small and medium-sized workpieces at multiple points. A single set of built-in frames 3 can independently complete the entire process of workpiece positioning, fixing, alignment processing and resetting unloading. The clamping structure is simple and the operation is efficient, which can meet the needs of rapid milling processing of small outer shells in conventional batches. At the same time, another set of built-in frames 3 can be left empty for pre-loading, realizing alternating operation and improving continuous processing efficiency. For large-size, large-span, and irregularly shaped wide medical equipment shells, a two-set of built-in frames 3 linkage limiting clamping mode is adopted. Due to the wide area and large center of gravity span of large-size workpieces, single-position clamping is prone to problems such as uneven force, slight end wobbling and processing vibration. At this time, the limiting components 10 corresponding to the two sets of built-in frames 3 can be activated simultaneously. The servo motor 11 drives the bidirectional lead screw 13 to rotate, adjusting the distance between the two sets of slide blocks 12. This allows the two sets of built-in frames 3 to be distributed correspondingly in the positioning areas at both ends or sides of the large workpiece. Subsequently, the two sets of limiting components 10 are activated synchronously, and multiple positioning plates 1007 on both sides simultaneously clamp and limit the workpiece symmetrically from both ends and sides. This bidirectional symmetrical clamping method forms a balanced clamping constraint force on the large workpiece, completely restricting its horizontal, vertical, and torsional degrees of freedom. It eliminates workpiece offset, micro-vibration, and warping problems caused by milling cutting forces, ensuring the overall milling flatness and contour accuracy of the large-size shell. Both clamping modes can be used with the equipment's vertical hydraulic rod 8 for lifting and lowering adjustment, horizontal lead screw feed adjustment, and subsequent slag removal and reset structure, adapting to the integrated precision milling needs of medical equipment shells of different sizes and specifications. This significantly improves the equipment's versatility and processing stability. Simultaneously, the two sets of built-in frames 3 can alternately complete loading and processing operations, further improving the equipment's continuous processing efficiency.

[0019] like Figure 1 , Figure 3 and Figure 4As shown, the built-in frame 3 has two sets, and a top plate 7 is installed on the top of the built-in frame 3. A hydraulic rod 8 is installed on the top of the top plate 7, and the output end of the hydraulic rod 8 is fixedly connected to the connecting frame 9. Slide rods 15 are fixedly installed on both sides of the bottom of the top plate 7, and the outside of the slide rods 15 is slidably connected to both sides of the connecting frame 9. A scraper 4 is fixedly installed on the bottom of the built-in frame 3, and the scraper 4 is slidably disposed on the surface of the bottom plate 1. An opening 14 is provided inside the bottom plate 1. During the entire milling process, a large amount of metal chips, dust and other processing waste will be generated. The equipment is equipped with a synchronous slag removal structure to ensure a clean processing environment and stable equipment operation. The scraper 4, fixed to the bottom of the built-in frame 3, is set against the surface of the base plate 1. As the built-in frame 3 moves laterally with the slide 12, the scraper 4 moves synchronously with the built-in frame 3, automatically scraping away the processing debris accumulated on the surface of the base plate 1. The debris collected by the scraper 4 will automatically fall and be collected through the drain 14 opened inside the base plate 1, avoiding debris accumulation in the processing area and preventing debris from affecting the workpiece positioning accuracy and milling effect, while reducing manual cleaning procedures. After the milling of a single batch of workpieces is completed, the equipment can automatically reset and unload by moving the position of the built-in frame 3: the servo motor 3 11 drives the bidirectional lead screw 13 to reverse, driving the slide 12 and the built-in frame 3 to move and reset to the initial loading and unloading position. Then, the limit component 10 releases the clamping limit on the workpiece, and the operator can quickly remove the processed medical device shell, completing a single integrated precision milling cycle, and the equipment can immediately enter the next batch of processing operations.

[0020] In summary, this precision milling machine for the integrated casing of the medical device is first based on... Figures 1-5The structure shown in the figure has the core positioning mechanism of the device as the limiting component 10 inside the built-in frame 3. It can realize the synchronous, equidistant, and precise fixing of multiple sets of medical device shell workpieces, ensuring the consistency of batch workpiece milling. During the clamping operation, the medical device shell workpiece to be processed is placed on the positioning station of the connecting frame 9, and then the servo motor 1001 of the limiting component 10 is started. Servo motor 1001 outputs torque to drive connecting plate 1003 to rotate. Connecting plate 1003 drives multiple sets of hinged connecting plates 1004 to move synchronously. Since the middle part of connecting plate 1004 slides with slide rail 1002 through slider 1005, slide rail 1002 forms a limiting and guiding effect on slider 1005, which can convert the rotational motion of connecting plate 1003 into the smooth extension and retraction displacement of connecting plate 1004. The equipment is equipped with five sets of connecting plates 1004, sliders 1005, connecting rods 1006 and positioning plates 1007 with identical structures. Driven by servo motor 1001, the five sets of positioning structures extend and retract synchronously and at equal intervals. The positioning plates 1007 at the end of connecting rods 1006 are pressed and adhered from the outside of the workpiece to complete the synchronous positioning and fixing of multiple sets of medical equipment shells.This limiting method can adaptively adapt to medical shell workpieces of different specifications, while ensuring uniform and secure clamping spacing of each workpiece, effectively preventing workpiece offset and shaking during milling, and ensuring the machining accuracy of precision milling from the source. After the workpiece is clamped, it is precisely transported to the milling processing area through horizontal and vertical dual-dimensional adjustment, matching the processing stroke of the milling component 6. During vertical adjustment, the hydraulic rod 8 at the top of the top plate 7 is activated, and the output end of the hydraulic rod 8 drives the connecting frame 9 to rise and fall vertically as a whole. At the same time, the slide rods 15 on both sides of the bottom of the top plate 7 slide and cooperate with the sides of the connecting frame 9 to limit and guide the rising and falling movement of the connecting frame 9, ensuring that the connecting frame 9 and the workpiece clamped at the bottom move smoothly vertically, accurately adjusting the vertical processing distance between the workpiece and the milling component 6, adapting to the milling processing needs of shells of different thicknesses. During horizontal adjustment, the servo motor 11 on the outside of the bottom plate 1 is activated, driving the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 drives the slide block 12 on the surface to perform horizontal linear reciprocating motion through thread transmission. Since the built-in frame 3 is fixed to the top of the slide block 12, When the slide 12 moves, it can drive the built-in frame 3 and the clamped workpiece to move laterally as a whole, precisely adjusting the lateral machining position of the workpiece and achieving precise alignment between the workpiece and the milling cutter. This equipment is symmetrically equipped with two sets of built-in frames 3, both of which can independently cooperate with the limiting component 10 to complete the workpiece clamping, forming two limiting and fixing modes: single-frame independent clamping and double-frame linkage clamping. It can be flexibly switched according to the size and specifications of the medical equipment shell, greatly expanding the processing and adaptability range of the equipment. The specific limiting working principle is as follows: For conventional small and medium-sized medical equipment... The outer shell of the medical device adopts a single set of built-in frame 3 limiting clamping mode. During operation, only one set of built-in frame 3 and its internal matching limiting components 10 are used to place one or more small outer shell workpieces on the work position of the connecting frame 9. The connecting plate 1003 is driven to rotate by the servo motor 1001. Relying on the guiding and limiting effect of the slide rail 1002 and the slider 1005, the five sets of connecting plates 1004 and connecting rods 1006 are driven to extend synchronously and equidistantly. The end positioning plate 1007 is used to press and clamp the outer side of the small and medium-sized workpieces at multiple points.Each set of built-in frames 3 can independently complete the entire process of workpiece positioning, fixing, alignment, and resetting / unloading. The clamping structure is simple and the operation is efficient, meeting the rapid milling needs of conventional batches of small shells. Simultaneously, another set of built-in frames 3 can be left idle for pre-loading, enabling alternating operations and improving continuous processing efficiency. For large-size, wide-span, and irregularly shaped medical equipment shells, a two-set of built-in frames 3 is used in a linked limiting clamping mode. Due to the wide area and large center of gravity span of large workpieces, single-position clamping can easily lead to uneven force distribution, end-end wobbling, and processing vibration. In this case, the limiting components 10 corresponding to the two sets of built-in frames 3 can be activated simultaneously. The servo motor 11 drives the bidirectional lead screw 13 to rotate, adjusting the distance between the two sets of slides 12, so that the two sets of built-in frames 3 are distributed at both ends or sides of the large workpiece's positioning area. Then, the two sets of limiting components 10 are activated simultaneously, and multiple positioning plates 1007 on both sides simultaneously symmetrically clamp and limit the workpiece from both ends and sides. This bidirectional symmetrical clamping method can handle large workpieces... A balanced clamping constraint is formed, completely restricting the horizontal, vertical, and torsional degrees of freedom of the workpiece, eliminating workpiece offset, micro-vibration, and warping problems caused by milling cutting forces, and ensuring the overall milling flatness and contour accuracy of large-size shells. Both clamping modes can be used with the vertical hydraulic rod 8 for lifting and lowering adjustment, the horizontal lead screw for feeding adjustment, and the subsequent slag removal and reset structure, adapting to the integrated precision milling needs of medical device shells of different sizes and specifications. The equipment's versatility and processing stability are greatly improved. At the same time, the two sets of built-in frames 3 can alternately complete the loading and processing operations, further improving the continuous processing efficiency of the equipment. When the workpiece is adjusted to the designated processing position, the milling component 6 inside the milling frame 2 is activated to complete the precision milling operation of the medical device shell. During the milling operation, the servo motor 601 drives the lead screw 602 to rotate. The lead screw 602 drives the milling part 603 to make precise displacement along the axis of the lead screw 602 through thread transmission. Combined with the previous horizontal and vertical position adjustment of the workpiece, the milling movement of the milling part 603 is realized.

[0021] Meanwhile, the CCD camera 604 mounted on the outside of the milling part 603 works in real time throughout the process, performing high-definition visual acquisition of the workpiece milling position, machining profile, and milling allowance, and feeding the machining data back to the equipment control system in real time. The control system can accurately identify problems such as machining deviation, workpiece position offset, and uneven milling allowance based on the visually acquired data, and assist in fine-tuning the operating parameters of the servo motor 601 in real time, accurately correcting the machining stroke and feed speed of the milling part 603 to achieve visual closed-loop precision machining. In addition, the equipment control system is electrically connected to the hydraulic rod 8 for linkage control. It can intelligently regulate the telescopic stroke and lifting rate of the hydraulic rod 8 according to the workpiece thickness, milling depth, and real-time machining conditions, automatically matching the vertical machining height of the workpiece, and dynamically correcting the vertical positioning position of the workpiece, so that the workpiece clamping height and milling depth always meet the precision machining standards, effectively ensuring the machining accuracy and machining consistency of the medical device housing, and meeting the production standards of high precision and high regularity for medical accessories. During the whole process of milling, a large amount of machining waste such as metal chips and dust will be generated. The equipment is equipped with a synchronous slag cleaning structure to ensure a clean machining environment and stable operation of the equipment. The scraper 4 fixed at the bottom of the built-in frame 3 is arranged to fit the surface of the bottom plate 1. During the lateral translation of the built-in frame 3 along with the slide seat 12, the scraper 4 moves synchronously with the built-in frame 3, automatically scraping the machining debris accumulated on the surface of the bottom plate 1. The debris scraped by the scraper 4 will automatically fall and be collected through the leakage opening 14 opened inside the bottom plate 1, avoiding debris accumulation in the machining area, preventing debris from affecting the workpiece positioning accuracy and milling effect, and reducing the manual cleaning process at the same time.
