[0022] This utility model is as follows Figures 1 to 5 As shown, a precision milling machine for glass processing includes a frame 10, a glass transfer mechanism 20 for moving the glass, and a milling mechanism 30 for milling the glass, wherein:

[0023] The frame 10 is equipped with a worktable 11 for mounting the glass transfer mechanism 20 and the milling mechanism 30. The glass transfer mechanism 20 includes a height adjustment component, a lifting drive component, a swing drive component, and a glass fixing component for fixing the glass. The height adjustment component is mounted on the worktable 11, and the lifting drive component is mounted at the output end of the height adjustment component. The swing drive component is mounted at the output end of the lifting drive component. The glass fixing component is mounted at the output end of the swing drive component. The glass in the glass fixing component can swing and corresponds to the milling mechanism 30. The height adjustment component is used to adjust the depth of glass milling. The lifting drive component is used to drive the glass to descend for milling and to drive the glass to rise after processing.

[0024] The glass transfer mechanism 20 is in its initial position, and the glass to be processed is installed on the glass fixing component. The milling depth is preset by the height adjustment component to determine the final relative position between the milling mechanism 30 and the glass surface. The lifting drive component drives the entire swing drive component and the glass fixing component to move downward, so that the fixed glass is smoothly moved towards the high-speed rotating milling mechanism 30. The glass contacts the milling mechanism 30 and milling begins. At the same time, the swing drive component starts to work, driving the glass fixing component and the glass on it to swing slowly and smoothly along a preset trajectory. After the current processing step is completed, the lifting drive component drives the glass fixing component and the processed glass to lift upward, so that it is completely separated from the milling mechanism 30.

[0025] The glass transfer mechanism 20 and the milling mechanism 30 work together. The glass transfer mechanism 20 moves the glass and adjusts its position, while the milling mechanism 30 mills the glass. The two work together to achieve glass milling, improving production efficiency and processing accuracy. The height adjustment component, lifting drive component, and swing drive component allow the glass to be adjusted in multiple dimensions, including height, lifting, and swing. The height adjustment component can adjust the depth of glass milling, the lifting drive component enables the glass to move up and down for milling, and the swing drive component allows the glass to swing, thus enabling milling of different parts of the glass, increasing processing flexibility and versatility. The synergistic effect of each component can precisely control the position and posture of the glass, ensuring accurate correspondence between the glass and the milling mechanism 30, and improving the accuracy and quality of milling.

[0026] The height adjustment assembly includes a support 211, a rotating handle 212, a screw 213, and a sliding seat 214. The support 211 is mounted on the worktable 11. The rotating handle 212 is rotatably mounted on the upper side of the support 211. The upper end of the screw 213 is fixedly connected to the rotating handle 212. The screw 213 is rotatably engaged with the sliding seat 214.

[0027] The lifting drive assembly includes a lifting drive cylinder 221 and a lifting slide 222. The lifting drive cylinder 221 is mounted on the slide 214, and the lifting slide 222 is mounted on the output end of the lifting drive cylinder 221; the lifting slide 222 serves as the output end.

[0028] The swing drive assembly includes a rotary motor 231, an eccentric wheel 232, a connecting rod 233, a drive rod 234, a first swing plate 235, a second swing plate 236, a rotating shaft 237, and a sleeve 238. The rotary motor 231 is mounted at the output end of the lifting drive assembly; the eccentric wheel 232 is mounted at the output end of the rotary motor 231; one end of the connecting rod 233 is slidably connected to the eccentric wheel 232; the other end of the connecting rod 233 is hinged to the rear end of the drive rod 234; the front end of the drive rod 234 is hinged to the first swing plate 235; the first swing plate 235 and the second swing plate 236 are respectively fastened to both sides of the rotating shaft 237; the sleeve 238 is mounted at the output end of the lifting drive assembly, and the rotating shaft 237 is rotatably located inside the sleeve 238.

[0029] The eccentric wheel 232 has a groove 2321 that passes through the center of the circle, and one end of the connecting rod 233 is slidably installed in the groove 2321 of the eccentric wheel 232.

[0030] By rotating the rotating handle 212, the screw 213 is driven to rotate. The screw 213 rotates in conjunction with the sliding seat 214, thereby realizing the up and down movement of the sliding seat 214, and thus adjusting the height of the glass. This allows for precise control of the glass milling depth, meeting the processing requirements of different glass products.

[0031] The lifting drive cylinder 221 drives the lifting slide 222 to move up and down, enabling the glass to descend quickly and stably for milling and to rise again after processing, thus improving processing efficiency. The rotary motor 231 in the swing drive assembly drives the eccentric wheel 232 to rotate. The eccentric wheel 232 engages with the connecting rod 233 via a groove 2321, causing the connecting rod 233 to drive the drive rod 234, which in turn drives the first swing plate 235 and the second swing plate 236 to swing, ultimately achieving the swinging of the glass. This swinging method allows the glass to change angles during milling, enabling comprehensive milling of edges and corners, improving processing integrity. The combination of the eccentric wheel 232 and the connecting rod 233 converts rotational motion into swinging motion, resulting in a simple, compact structure that is easy to implement and maintain. The groove 2321 on the eccentric wheel 232 allows the connecting rod 233 to slide within it, achieving a flexible conversion from rotational to swinging motion. This ensures the normal operation of the swing drive assembly, reduces friction and wear during movement, and extends the service life of the components.

[0032] The glass fixing assembly includes a rocker arm 241 and a fixture 242 for fastening the glass. The rocker arm 241 is fixedly mounted on the second rocker plate 236, and the fixture 242 is detachably mounted on the lower end of the rocker arm 241. The fixture 242 fastens the glass by means of a vacuum suction cup. The lower end of the fixture 242 has a feeding groove that matches the glass, and the glass is fastened to the lower side of the fixture 242 by vacuum suction. The fixture 242 is detachably mounted on the lower end of the rocker arm 241. The detachable mounting method includes quick-change pin connection and threaded quick-change joint installation.

[0033] The fixture 242 is detachably mounted on the lower end of the rocker arm 241, making it easy and quick to replace. The appropriate fixture 242 can be replaced according to the size and shape of different glass, which improves the versatility and adaptability of the equipment.

The protective cover 31, mounted on the worktable 11, covers the grinding wheel 33, preventing glass shards and dust generated during the milling process from flying out, protecting the safety of the operator, and also reducing pollution to the surrounding environment. The rotary drive motor 32 drives the grinding wheel 33 to rotate at high speed, enabling efficient milling of the glass. The grinding wheel 33, located within the protective cover 31, ensures the stability and reliability of the milling process. The glass transfer mechanism 20 and the milling mechanism 30 mill the flat glass surface into a bridge-shaped arc.

[0035] This precision milling and grinding machine for glass processing also includes a CNC system. Both the glass transfer mechanism 20 and the milling mechanism 30 are electrically connected to the CNC system. The grinding wheel 33 is driven by a high-precision rotary drive motor 32, and its rotation speed is precisely controlled by the CNC system. The grinding wheel 33 can be made of different materials and grit sizes depending on the processing requirements, such as a diamond grinding wheel 33 for rough grinding and a resin grinding wheel 33 for fine grinding. By coordinating the milling and grinding process through the CNC system, the equipment can perform integrated precision machining of watch glass, achieving a seamless transition from roughing to finishing, significantly improving processing efficiency and quality.

[0036] The CNC system allows for precise control of the glass transfer mechanism 20 and the milling mechanism 30 through adjustments made by the operator. Parameter settings can be conveniently configured via the control panel.

[0038] The following are some key technical parameters in the milling process:

[0039] Processing Glass Size Range: The equipment can process watch glass up to 36mm x 36mm and 10mm x 10mm in maximum size, making it suitable for various watch glass sizes.

Different thicknesses require different pressure and speed parameters from the equipment, necessitating good adaptability. Milling Rocker Speed: The milling speed of the milling rocker can be adjusted according to the glass material and processing requirements, adjusting the swing amplitude and distance to ensure milling quality and efficiency. Milling Accuracy: A key indicator of processing quality, dimensional accuracy is controlled within ±0.02mm. Shape accuracy (such as flatness and roundness) also has strict standards. High-precision milling improves the aesthetics and assembly accuracy of watch glass. Grinding Wheel Speed: The rotational speed of the grinding wheel, which can reach 3000rpm. The speed directly affects processing efficiency and quality.

[0040] The operating method and principle of this precision milling machine used in glass processing are as follows:

[0041] The glass transfer mechanism is in its initial position, and the glass to be processed is already installed on the glass fixing component. The milling depth is preset by the height adjustment component to determine the final relative position between the milling mechanism and the glass surface. The lifting drive component drives the entire swing drive component and the glass fixing component to move downward, so that the fixed glass is smoothly moved towards the high-speed rotating milling mechanism. The glass contacts the milling mechanism and milling begins. At the same time, the swing drive component starts working, driving the glass fixing component and the glass on it to swing slowly and smoothly along a preset trajectory.

The height adjustment component allows for precise preset and fine-tuning of the processing depth, making it widely applicable. The swing drive component creates relative motion between the glass and the milling mechanism, avoiding uneven processing caused by localized contact and significantly improving the flatness, smoothness, and contour accuracy of the processed surface.
