Description

Technical Field

[0001] This invention relates to the field of milling equipment technology, and in particular to a milling equipment for producing molds for processing watch movement components. Background Technology

[0002] Milling equipment is a machine tool that uses a rotating cutting tool to perform multi-surface machining on a workpiece. Its core functions include cutting planes, grooves, curved surfaces, and complex shapes. In the field of modern precision manufacturing, especially in the milling of watch movement molds, the dynamic stability of milling equipment directly determines the quality and pass rate of the final product. These molds are usually characterized by complex structure, fine features, strict tolerance requirements, and high material hardness.

[0003] In the milling of watch movement molds, the spindle system is a core component. Under long-term high-speed operation, the spindle will experience uneven thermal expansion due to heat generation, resulting in minute wear gaps under long-term high load. This produces a small but fatal deflection. Traditional equipment relies on regular maintenance and operator experience, and cannot detect and correct this gradual deflection in real time during the processing. This leads to dimensional deviations in mold processing, reduced surface finish, and even scrap. Summary of the Invention

A drive motor 706 is provided on the side of the tooling cover plate 9 away from the main spindle housing 3.

[0026] Specifically, when the equipment starts for precision milling, the drive motor 706, through the meshing of the linkage gear 711 and the rotating gear 709, drives the main shaft 707 and its end locking tool holder 708 to rotate at high speed. Simultaneously, the blower 704 continuously operates, and cooling airflow is delivered to the hollow blower frame 702 via the hose 705 and connecting pipe 703, evenly blowing onto the main shaft 707 and gear set. This proactively reduces frictional temperature rise from the source, delaying thermal deformation. As machining continues, the main shaft, due to long-term load and internal friction, does not... Minor temperature rises and potential wear are unavoidable. At this point, the core early warning compensation mechanism 7 begins to play a crucial role. The capacitive displacement sensor 726, mounted on the adjustable opening and closing tooling rod 723, is adjusted to the optimal detection position under the drive of the general-purpose motor 725, performing millisecond-level high-precision radial measurement of the main shaft 707 in a non-contact manner. Simultaneously, the nearby temperature sensor 718 monitors the shaft temperature in real time. All sensor data is transmitted to the alarm controller 737 in real time, which continuously analyzes the displacement and temperature data. Once the analysis model determines that the radial runout of the spindle caused by uneven thermal expansion or wear gaps exceeds the preset micron-level safety threshold, the system immediately enters the early warning compensation process. First, the controller triggers an early warning signal. Then, it sends a precise command to the electric telescopic rod 736, which starts and pushes the push rod 733 to move along the slide groove 727. The inclined plates 735 on both sides of the push rod 733 are displaced accordingly. The inclined surface of the inclined plate 735 contacts the moving roller 734 at the end of the arc-shaped positioning rod 731 and overcomes the torsion spring 730. The preload force converts the linear thrust into the opposite rotation of two arc-shaped positioning rods 731 around the rotating shaft 729. Ultimately, the positioning rollers 732 at the front end of the arc-shaped positioning rods 731 and the positioning rollers 732 on the push rod 733 are precisely and stably pressed against the outer surface of the main shaft 707 in a surrounding manner. By applying this controllable radial correction force, the system can push back or constrain the main shaft that has a slight deflection in real time and dynamically, thereby directly compensating for the error source without stopping the machine and ensuring the spatial position accuracy of the cutting point. In specific application scenarios, the integrated intelligent early warning compensation mechanism 7 enables online, real-time, and dynamic monitoring and correction of the spindle's operating status. The precision sensor network composed of the capacitive displacement sensor 726 and the temperature sensor 718 can capture micron-level deflections caused by thermal deformation or wear of the spindle in milliseconds. The alarm controller 737 intelligently judges these deviations; if they exceed the tolerance, the system immediately drives the mechanical mechanism within the compensation fixture frame 713, causing the positioning roller 732 to apply a precise radial compensation force to the main shaft 707. This fundamentally overturns the passive mode of traditional equipment—"discovery after the fact, shutdown for maintenance"—enabling continuous processing... Actively maintaining spindle precision during the process directly improves the dimensional consistency and surface finish of ultra-precision parts such as watch movement molds, reducing the scrap rate caused by progressive spindle deflection to an extremely low level. At the same time, the addition of auxiliary heat dissipation systems, including blowers 704 and hollow air-blowers 702, effectively controls spindle temperature rise from the source and slows down thermal expansion, the main cause of deflection, forming a dual guarantee of "prevention and correction." This not only enhances the stability of precision control but also helps extend the service life of key components such as spindle bearings by reducing the thermal load on the spindle, thus improving the overall durability of the equipment.

[0030] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, a servo motor 808 is provided on one side of the tooling support rod 805, and the drive end of the servo motor 808 is connected to the other end of the rotating column 807 via a coupling. A plug rod 814 is fixedly connected to the side of the lower lifting cylinder 810 facing the discharge collection pipe 806.

[0031] Specifically, to ensure the long-term stability of the entire precision machining and monitoring environment, the anti-clogging module 8 operates synchronously. The pump body 801 pumps coolant into the hollow circular frame 815 near the tool, and sprays it out through the spray hole 816 to cool the tool and flush away debris. The waste liquid containing debris flows into the waste liquid tank 804 and into the discharge collection pipe 806. To prevent the accumulation of tiny debris and blockage of the pipe, the servo motor 808 drives the rotating circular plate 812 to rotate. Through the cooperation of the push-pull cylinder 813 and the push-pull support frame 811, the rotational motion is converted into the linear reciprocating motion of the lifting cylinder 810 and the insertion rod 814. The insertion rod 814 is periodically inserted into the discharge collection pipe 806 for mechanical unblocking to ensure that the waste liquid discharge is always unobstructed and to avoid secondary pollution or environmental interference caused by poor chip discharge. In specific application scenarios, the anti-clogging module 8 solves the problem of poor coolant chip removal in precision machining. The servo motor 808 drives the insertion rod 814 to automatically and periodically unclog the discharge collection pipe 806, ensuring the long-term cleanliness and unobstructed flow of the processing area and waste liquid path. This avoids secondary pollution of workpieces and equipment caused by coolant splashing due to blockage.

[0032] Working Principle: When the equipment starts for precision milling, the drive motor 706, through the meshing of the linkage gear 711 and the rotating gear 709, drives the main shaft 707 and its end locking tool holder 708 to rotate at high speed. Simultaneously, the blower 704 continuously operates, and cooling airflow is delivered to the hollow blower frame 702 via the hose 705 and connecting pipe 703, evenly blowing onto the main shaft 707 and gear set. This proactively reduces frictional temperature rise from the source, delaying thermal deformation. As machining continues, the main shaft inevitably experiences slight temperature rise and potential wear due to long-term load and internal friction. At this point, the core early warning compensation mechanism 7 begins to play a crucial role. The capacitive displacement transmission mechanism mounted on the adjustable opening and closing tooling rod 723... Sensor 726, driven by general-purpose motor 725, adjusts to the optimal detection position to perform millisecond-level high-precision radial measurement of the main shaft 707 in a non-contact manner. Simultaneously, nearby temperature sensor 718 monitors the shaft temperature in real time. All sensor data is transmitted to alarm controller 737 in real time. Alarm controller 737 continuously analyzes the displacement and temperature data streams. Once the analysis model determines that the radial runout of the main shaft due to uneven thermal expansion or wear clearance exceeds a preset micron-level safety threshold, the system immediately enters the early warning compensation process. First, the controller triggers an early warning signal. Then, it sends a precise command to electric telescopic rod 736, which activates, pushing push rod 733 along slide groove 727. The inclined plates 735 on both sides of the moving rod 733 move accordingly. The inclined surface of the inclined plate 735 contacts the moving roller 734 at the end of the arc-shaped positioning rod 731, and overcomes the preload of the torsion spring 730, converting the linear thrust into the opposite rotation of the two arc-shaped positioning rods 731 around the rotation axis 729. Ultimately, this drives the positioning roller 732 at the front end of the arc-shaped positioning rod 731 and the positioning roller 732 on the pushing rod 733 to press precisely and stably against the outer surface of the main rotating shaft 707 in a surrounding manner. By applying this controllable radial correction force, the system can push back or constrain the spindle that has undergone slight deflection in real time and dynamically, thereby directly compensating for the error source without stopping the machine, ensuring the spatial position accuracy of the cutting point, and ensuring the overall To ensure the long-term stability of the precision machining and monitoring environment, the anti-clogging module 8 operates synchronously. The pump body 801 pumps coolant into the hollow circular frame 815 near the tool, and sprays it out through the spray hole 816 to cool the tool and flush away debris. The waste liquid containing debris flows into the waste liquid tank 804 and into the discharge collection pipe 806. To prevent the accumulation of tiny debris and blockage of the pipe, the servo motor 808 drives the rotating circular plate 812 to rotate. Through the cooperation of the push-pull cylinder 813 and the push-pull support frame 811, the rotational motion is converted into the linear reciprocating motion of the lifting cylinder 810 and the insertion rod 814. The insertion rod 814 is periodically inserted into the discharge collection pipe 806 for mechanical unblocking, ensuring that the waste liquid discharge is always unobstructed and avoiding secondary pollution or environmental interference caused by poor chip discharge.
