Technical Field

[0001] This invention relates to the field of milling and polishing equipment technology, and in particular to an integrated milling and polishing equipment and method for producing supporting components for high-speed embroidery machines. Background Technology

[0002] The milling and polishing integrated equipment for high-speed embroidery machine parts is a precision machining equipment designed specifically for processing core metal parts of embroidery machines (such as spindle boxes). It integrates the traditionally separate milling (removing blank allowance and forming complex curved surfaces) and polishing (removing milling marks and improving surface finish) processes into the same machine, and can continuously complete the entire process from roughing to fine surface treatment with a single clamping.

[0003] While existing integrated equipment can automate the processing of most parts, the special shape of the spindle box of the embroidery machine makes it easy to deform using ordinary clamping parts. In addition, the spindle box is large in size, requiring the design of special transfer components for loading and unloading. Therefore, designing an integrated processing equipment for milling and polishing the spindle box is a problem that technicians urgently need to solve. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

The three-axis assembly is located at the end point of the conveyor, and the milling cutter and polishing wheel on the three-axis assembly face the conveyor. The pickup assembly includes a bracket, and a rotating roller is rotatably mounted on the top of the bracket. The rotating roller can rotate under the drive of a drive device. One end of the rotating roller is fixedly connected to a pickup frame through a telescopic cylinder. After the pickup frame fixes the part to be processed, it rotates 90 degrees so that the processing surface of the part faces the milling cutter and polishing wheel. Under the drive of the three-axis assembly, the milling cutter and polishing wheel perform milling and polishing processing on the processing surface of the part according to a preset path.

[0006] Preferably, the conveyor is a roller type or a belt type, and the end point of the conveyor is equipped with a distance sensor. The distance sensor monitors the real-time position of the parts, thereby controlling the timing of picking up the components.

[0007] Preferably, the rear end of the part has a mounting base, and the mounting base and the part have a mounting groove and a mounting block respectively. The mounting groove and the mounting block fit into each other, and the mounting base and the part are fixed by bolts. Both ends of the part have shaft holes.

[0008] Preferably, a limiting rod is fixedly connected to one end of the pickup frame near the rotating roller, and a limiting sleeve is fixedly connected to the bottom of the rotating roller. The limiting rod and the limiting sleeve are slidably connected, and the shape of the pickup frame matches the shape of the inner wall of the part.

[0009] Preferably, a sliding groove is provided at one end of the pickup frame near the shaft hole, and a limiting post is slidably connected inside the sliding groove. The diameter of the limiting post matches the inner diameter of the shaft hole. A sliding groove is provided on the inner wall of the sliding groove, and a slider is fixedly connected to the outer wall of the limiting post. The slider is slidably connected to the sliding groove, and an electromagnetic spring is fixedly connected between the limiting post and the inner wall of the sliding groove. The outer diameter of the limiting post near the shaft hole decreases.

[0010] Preferably, the three-axis assembly has a base at its bottom. The three-axis assembly includes a vertical axis and a horizontal axis. The bottom of the vertical axis is fixedly connected to the base. One end of the horizontal axis is slidably connected to the vertical axis. A vertical axis is slidably mounted on the horizontal axis. The vertical axis can slide along the horizontal axis. A slide block is slidably mounted on the vertical axis. A milling cutter and a polishing wheel are mounted on the slide block.

[0011] Preferably, a slide rail is fixedly connected to the side of the slide block, a milling cutter sleeve is provided at one end of the milling cutter, the milling cutter sleeve is slidably connected to the upper end of the slide rail, the milling cutter is rotatably connected to the milling cutter sleeve, a milling cutter motor is installed at one end of the milling cutter sleeve, the milling cutter motor drives the milling cutter to rotate, and a milling cutter telescopic rod is fixedly connected between the end of the milling cutter sleeve and the end of the slide rail.

[0012] Preferably, one end of the polishing wheel has a polishing wheel sleeve, the polishing wheel sleeve is slidably connected to the lower end of the slide rail, the polishing wheel is rotatably connected to the polishing wheel sleeve, a polishing wheel motor is installed at one end of the polishing wheel sleeve, the polishing wheel motor drives the polishing wheel to rotate, and a polishing wheel telescopic rod is fixedly connected between the polishing wheel sleeve and the end of the slide rail.

[0013] Preferably, the three-axis assembly has a guide groove at the bottom, the bottom of which is fixed to the top of the base, and the guide groove discharges the debris generated during milling and polishing.

[0014] On the other hand, the present invention provides a milling and polishing method for producing supporting components for high-speed embroidery machines, comprising the following steps: S1. Place the part to be processed smoothly on the conveyor with the opening facing upwards, and transport the part to the end point of the conveyor. S2. When the part reaches the end of the conveying process, the telescopic cylinder of the pickup assembly is extended, driving the pickup frame to descend and lock the part in place. Then, the rotating roller at the top of the bracket drives the pickup frame and the fixed matching parts to rotate 90 degrees as a whole, so that the originally downward processing surface changes from vertically downward to facing the three-axis assembly. S3. Control the three-axis assembly to move along the preset path trajectory, drive the milling cutter on it to approach and align with the machining surface of the matching component after adjustment in step S2, and perform milling operation to remove the excess material on the machining surface. S4. After the milling process is completed, control the three-axis assembly to switch to the polishing wheel, and drive the polishing wheel to polish the milled surface according to the preset polishing path. S5. After processing is completed, control the three-axis assembly to return to its original position, and the rotating roller of the pickup assembly rotates in the opposite direction by 1-90 degrees, so that the part falls onto the conveyor. The pickup frame releases the part to complete the unloading. The conveyor continues to operate to output the processed part. At this time, the next part to be processed is located below the pickup assembly. S6. Repeat steps S2-S5 to process the parts on the conveyor in sequence.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. This invention fundamentally solves the problem of stress deformation of irregularly shaped thin-walled parts during clamping by using a pickup frame that matches the shape of the inner wall of the part as the core support structure. Compared with traditional external clamping or point contact fixing, this solution achieves full internal fit support. Under the high load conditions of milling and polishing, it can effectively disperse cutting forces and avoid part contour distortion caused by clamping force concentration or processing vibration, significantly improving the processing accuracy and product qualification rate of key components such as the embroidery machine spindle box.

[0016] 2. This invention, by setting up a flipping mechanism consisting of rotating rollers and telescopic cylinders, enables the equipment to automatically complete the conversion of parts from a horizontal conveying posture to a vertical processing posture. This design eliminates the steps required by traditional processes, such as manual intervention or the use of complex flipping tables to adjust the workpiece angle. It not only eliminates positioning errors caused by secondary clamping but also significantly shortens the auxiliary time for loading, unloading, and posture adjustment, realizing seamless continuous operation of milling and polishing processes at the same station.

[0017] 3. This invention utilizes the mating structure of the limiting post and the shaft hole, combined with the driving mechanism of an electromagnetic spring, to achieve precise center positioning and axial locking of the part. The tapered design at the end of the limiting post facilitates insertion into the shaft hole, while the fit between the slider and the groove ensures the smoothness of the extension and retraction process. This positioning method, based on the structural characteristics of the part itself (shaft hole), eliminates the need for a complex vision recognition system and can adapt to parts with certain dimensional tolerances, ensuring the uniformity of machining datum and the stability of clamping.

[0018] 4. This invention integrates a milling cutter and a polishing wheel on the same slide, and utilizes the extension rods of the milling cutter and the polishing wheel to achieve independent extension and retraction switching between the two, completing the entire process from roughing to finishing on a single machine. This integrated design avoids collisions and precision loss caused by parts moving between different machines. Simultaneously, in conjunction with the guide groove on the base, milling metal chips and polishing dust can be promptly discharged from the working area, preventing debris accumulation from scratching the machined surface or entering the transmission mechanism, thus ensuring the long-term stable operation of the equipment.

[0019] 5. This invention constructs a feeding system with sensing capabilities by using a roller or belt conveyor in conjunction with a distance sensor. The system can intelligently determine and trigger the action of the picking component based on the real-time position of the parts on the conveyor, solving the synchronization problem of automatic feeding of large, irregularly shaped parts. This "sensing-response" mechanism enables the equipment to adapt to assembly line operations with varying rhythms, improving the automation compatibility and reliability of the entire production line.

Detailed Implementation

[0023] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides an integrated milling and polishing equipment for producing high-speed embroidery machine components, including a conveyor 1, a pickup assembly 2, and a three-axis assembly 3. A milling cutter 4 and a polishing wheel 5 are mounted on the three-axis assembly 3. The part 6 to be processed is placed on the conveyor 1 with its opening facing upwards. The three-axis assembly 3 is located at the end point of the conveyor 1, and the milling cutter 4 and polishing wheel 5 on the three-axis assembly 3 face the conveyor 1. The pickup assembly 2 includes a bracket 7, and a rotating roller 8 is rotatably mounted on the top of the bracket 7. The rotating roller 8 can rotate under the drive of a drive device (not shown in the figure). One end of the rotating roller 8 is fixedly connected to a pickup frame 10 via a telescopic cylinder 9. After the pickup frame 10 fixes the part 6 to be processed, it rotates 90 degrees so that the processing surface of the part 6 faces the milling cutter 4 and polishing wheel 5. Under the drive of the three-axis assembly 3, the milling cutter 4 and polishing wheel 5 perform milling and polishing processing on the processing surface of the part 6 according to a preset path.

[0025] The conveyor 1 is either a roller type or a belt type. A distance sensor (not shown in the figure) is installed at the end point of the conveyor 1. The distance sensor monitors the real-time position of the part 6, thereby controlling the picking timing of the picking component 2.

[0026] like Figure 4As shown, the rear end of part 6 has a mounting base 11, and there are mounting grooves 12 and mounting blocks 13 between the mounting base 11 and part 6 respectively. The mounting grooves 12 and mounting blocks 13 fit into each other. The mounting base 11 and part 6 are fixed by bolts. Both ends of part 6 have shaft holes 14.

[0027] like Figure 5 As shown, a limiting rod 15 is fixedly connected to one end of the pickup frame 10 near the rotating roller 8, and a limiting sleeve 16 is fixedly connected to the bottom of the rotating roller 8. The limiting rod 15 and the limiting sleeve 16 are slidably connected, and the shape of the pickup frame 10 matches the shape of the inner wall of the part 6.

[0028] like Figure 6 As shown, a sliding groove 17 is provided at one end of the pickup frame 10 near the shaft hole 14. A limiting post 18 is slidably connected inside the sliding groove 17. The diameter of the limiting post 18 matches the inner diameter of the shaft hole 14. A sliding groove 19 is provided on the inner wall of the sliding groove 17. A slider 20 is fixedly connected to the outer wall of the limiting post 18. The slider 20 is slidably connected to the sliding groove 19. An electromagnetic spring 21 is fixedly connected between the limiting post 18 and the inner wall of the sliding groove 17. The outer diameter of the limiting post 18 near the shaft hole 14 decreases.

[0029] like Figure 7 , Figure 8 As shown, the three-axis assembly 3 has a base 22 below it. The three-axis assembly 3 includes a vertical axis 23 and a horizontal axis 24. The bottom of the vertical axis 23 is fixedly connected to the base 22. One end of the horizontal axis 24 is slidably connected to the vertical axis 23. A longitudinal axis 25 is slidably mounted on the horizontal axis 24. The longitudinal axis 25 can slide along the horizontal axis 24. A slide block 26 is slidably mounted on the longitudinal axis 25. The milling cutter 4 and the polishing wheel 5 are mounted on the slide block 26.

[0030] like Figure 9 , Figure 10 , Figure 11 As shown, a slide rail 27 is fixedly connected to the side of the slide block 26, and a milling cutter sleeve 28 is provided at one end of the milling cutter 4. The milling cutter sleeve 28 is slidably connected to the upper end of the slide rail 27, and the milling cutter 4 is rotatably connected to the milling cutter sleeve 28. A milling cutter motor 29 is installed at one end of the milling cutter sleeve 28, and the milling cutter motor 29 drives the milling cutter 4 to rotate. A milling cutter telescopic rod 30 is fixedly connected between the end of the milling cutter sleeve 28 and the end of the slide rail 27.

[0031] One end of the polishing wheel 5 has a polishing wheel sleeve 31, which is slidably connected to the lower end of the slide rail 27. The polishing wheel 5 is rotatably connected to the polishing wheel sleeve 31. A polishing wheel motor 32 is installed at one end of the polishing wheel sleeve 31, which drives the polishing wheel 5 to rotate. A polishing wheel telescopic rod 33 is fixed between the polishing wheel sleeve 31 and the end of the slide rail 27.

[0032] like Figure 7As shown, the triaxial assembly 3 has a guide groove 34 at its bottom. The bottom of the guide groove 34 is fixed to the top of the base 22. The guide groove 34 discharges the debris generated during milling and polishing.

[0033] In the above scheme, the milling cutter extension rod 30 and the polishing wheel extension rod 33 can respectively drive the milling cutter 4 and the polishing wheel 5 to approach or move away from the surface to be machined of the part 6, thereby achieving the purpose of free switching and being able to complete milling and polishing work respectively.

[0034] Example 2: The technical solution of this example differs from that of Example 1 in that this example provides a solution including the following steps: S1. After the equipment is started, the part 6 (embroidery machine spindle box) to be processed is placed on the conveyor 1 with its opening facing upwards. The conveyor 1 uses roller or belt drive to continuously transport part 6 to the end point. To ensure the accuracy of picking, a distance sensor (not shown in the figure) is installed at the end point of the conveyor 1, which constitutes the "sensory nerve" of the equipment. When part 6 moves with the conveyor 1 and enters the monitoring range of the sensor, the system calculates the running trajectory and current position of part 6 in real time. Once it is detected that part 6 has reached the preset optimal picking position, the control system immediately sends a signal, and the conveyor 1 stops running or switches to a low-speed micro-motion mode, thereby eliminating the displacement deviation of part 6 caused by inertia and providing a precise positioning basis for subsequent gripping actions.

[0035] S2. After receiving the gripping command, the pickup assembly 2 begins to operate. Driven by a drive device (such as a servo motor, not shown in the figure), the rotating roller 8 at the top of the support 7 first makes a fine adjustment to align with the center line of the part 6. Then, the telescopic cylinder 9 (such as a pneumatic or hydraulic cylinder) extends, pushing the pickup frame 10, which is fixedly connected to it, towards the part 6. Because the outline of the pickup frame 10 is specially designed to closely match the shape of the inner wall of the part 6, the pickup frame 10 can smoothly embed into the internal cavity of the part 6, forming a surface contact support.

[0036] At this point, the electromagnetic spring 21 inside the sliding groove 17 is initially in a contracted state, causing the limiting post 18 to be hidden inside the sliding groove 17. When the pickup frame 10 is fully in place, the electromagnetic spring 21 is energized to generate magnetic or elastic force and quickly extends, pushing the limiting post 18 to slide outward along the sliding groove 19. The tapered design at the front end of the limiting post 18 serves as a guide, allowing it to be accurately inserted into the shaft holes 14 at both ends of the part 6. As the limiting post 18 is further inserted, through the precise cooperation between the slider 20 and the sliding groove 19, the part 6 and the pickup frame 10 are forced to remain concentric in the radial direction, achieving high-precision center positioning and rigid locking. At the same time, the limiting rod 15 slides along the limiting sleeve 16, providing additional bending moment support for the entire pickup frame 10, ensuring that it will not wobble or sag during subsequent flipping.

[0037] S3. After rigid locking is completed, the rotating roller 8 begins to rotate 90 degrees under the drive of the drive device. This rotational motion is transmitted to part 6 through the telescopic cylinder 9 and the pickup frame 10, changing part 6 from its initial horizontal conveying posture to a vertical (or a specific angle required by the process) machining posture. This step cleverly utilizes the combination of gravity direction and machining requirements, turning part 6, which was originally open upwards, into a side-facing position facing the three-axis assembly 3, thereby exposing the machining surface that needs to be milled and polished. At this time, the telescopic cylinder 9 can fine-tune the distance between part 6 and the tool according to the specific machining allowance, ensuring the accuracy of the machining zero point.

[0038] S4. After part 6 is positioned, the three-axis assembly 3 begins to perform the core machining task. The vertical axis 23, horizontal axis 24 and vertical axis 25 constitute a precise spatial rectangular coordinate system motion mechanism. The three coordinate to drive the slide 26 to move precisely to the machining starting point.

[0039] Milling process: The control system controls the extension rod 30 of the milling cutter to extend, pushing the milling cutter sleeve 28 to slide downward along the slide rail 27 until the milling cutter 4 contacts the surface of the part 6. Subsequently, the milling cutter motor 29 starts, driving the milling cutter 4 to rotate at high speed. Under the control of the longitudinal axis 25 and the three-axis linkage, the part 6 is subjected to high-precision milling (such as grooving, de-weighting, contour trimming, etc.) according to the preset CAD / CAM path.

[0040] Process switching: After milling is completed, the milling cutter extension rod 30 retracts, raising the milling cutter 4 to a safe height to avoid interference. Immediately afterwards, the polishing wheel extension rod 33 extends, driving the polishing wheel sleeve 31 to move along the slide rail 27 towards the surface of the part 6.

[0041] Polishing process: The polishing wheel motor 32 starts, driving the polishing wheel 5 to rotate at high speed. The polishing wheel 5 contacts the surface of the part 6, using the grinding action to remove the tool marks and burrs left by milling, and improve the surface finish.

[0042] Throughout the entire processing, the guide trough 34 above the base 22 is always in operation. Using gravity or negative pressure (depending on the specific configuration), it collects and discharges the metal chips generated during milling and the dust generated during polishing in a timely manner, preventing chip accumulation from affecting processing accuracy or damaging the cutting tools.

[0043] S5. After processing, the three-axis assembly 3 returns to its origin. The rotating roller 8 rotates 90 degrees in the opposite direction under the drive of the drive unit, restoring part 6 from a vertical processing posture to a horizontal state. At this time, the electromagnetic spring 21 is de-energized, the magnetic or elastic force disappears, and the limiting post 18 retracts into the sliding groove 17 under the action of the reset force, disengaging from the shaft hole 14 and releasing the lock on part 6. Subsequently, the telescopic cylinder 9 retracts, driving the pickup frame 10 to be pulled out of the inner cavity of part 6. The released finished part 6 can be picked up by an end effector (such as another robotic arm or pushing mechanism) or directly fall back onto conveyor 1 (or another conveyor line) and transported away from the work area. All components of the equipment reset, awaiting the start of the next work cycle.

[0044] In summary, this invention fundamentally solves the problem of stress deformation of irregularly shaped thin-walled parts during clamping by using a pickup frame 10 that matches the shape of the inner wall of part 6 as the core support structure. Compared with traditional external clamping or point contact fixing, this solution achieves full internal fit support. Under the high load conditions of milling and polishing, it can effectively disperse cutting forces and avoid distortion of the contour of part 6 caused by concentrated clamping force or processing vibration. It significantly improves the processing accuracy and product qualification rate of key components such as the spindle box of the embroidery machine. By setting a flipping mechanism composed of rotating roller 8 and telescopic cylinder 9, the equipment can automatically complete the conversion of part 6 from a horizontal conveying posture to a vertical processing posture. This design eliminates the need for manual intervention or complex workpiece angle adjustments required in traditional processes. It not only eliminates positioning errors caused by secondary clamping but also significantly reduces auxiliary time for loading, unloading, and posture adjustment. This allows for seamless continuous operation of milling and polishing processes at the same station. Utilizing the mating structure of the limiting post 18 and the shaft hole 14, combined with the driving mechanism of the electromagnetic spring 21, precise center positioning and axial locking of part 6 are achieved. The tapered design at the end of the limiting post 18 facilitates insertion into the shaft hole 14, while the fit between the slider 20 and the groove 19 ensures the smoothness of the extension and retraction process. This positioning method, based on the structural characteristics of the part itself (shaft hole 14), eliminates the need for a complex vision recognition system and can adapt to parts with certain dimensional tolerances, ensuring the uniformity of the machining datum and the stability of the clamping. By integrating the milling cutter 4 and the polishing wheel 5 on the same slide 26 and utilizing the extension rod 30 of the milling cutter and the extension rod 33 of the polishing wheel to achieve independent extension and retraction switching between the two, the entire process from roughing to finishing is completed on a single machine. This integrated design avoids collisions and precision loss caused by parts moving between different devices. Simultaneously, the guide trough 34 on the base 22 effectively removes milling metal chips and polishing dust from the working area, preventing chip accumulation from scratching machined surfaces or entering the transmission mechanism, thus ensuring long-term stable operation of the equipment. A roller or belt conveyor 1, combined with a distance sensor, constructs a sensing-enabled feeding system. The system can intelligently determine and trigger the action of the picking component 2 based on the real-time position of the part 6 on the conveyor 1, solving the synchronization problem of automatic feeding of large, irregularly shaped parts. This "sensing-response" mechanism allows the equipment to adapt to production line operations with varying rhythms, improving the automation compatibility and reliability of the entire production line.

10. A milling and polishing method for producing accessories for a high-speed embroidery machine, employing an integrated milling and polishing equipment for producing accessories for a high-speed embroidery machine as described in any one of claims 1-9, characterized in that... Includes the following steps: S1. Place the part to be processed smoothly on the conveyor with the opening facing upwards, and transport the part to the end point of the conveyor. S2. When the part reaches the end of the conveying process, the telescopic cylinder of the pickup assembly is extended, driving the pickup frame to descend and lock the part in place. Then, the rotating roller at the top of the bracket drives the pickup frame and the fixed matching parts to rotate 90 degrees as a whole, so that the originally downward processing surface changes from vertically downward to facing the three-axis assembly. S3. Control the three-axis assembly to move along the preset path trajectory, drive the milling cutter on it to approach and align with the machining surface of the matching component after adjustment in step S2, and perform milling operation to remove the excess material on the machining surface. S4. After the milling process is completed, control the three-axis assembly to switch to the polishing wheel, and drive the polishing wheel to polish the milled surface according to the preset polishing path. S5. After processing is completed, control the three-axis assembly to return to its original position, and the rotating roller of the pickup assembly rotates in the opposite direction by 1-90 degrees, so that the part falls onto the conveyor. The pickup frame releases the part to complete the unloading. The conveyor continues to operate to output the processed part. At this time, the next part to be processed is located below the pickup assembly. S6. Repeat steps S2-S5 to process the parts on the conveyor in sequence.
