Description

Technical Field

[0001] This utility model relates to the field of milling equipment technology, and in particular to a high-precision CNC glass mold milling device. Background Technology

[0002] A milling machine is a mechanical processing equipment or tool system that uses a milling cutter to cut a workpiece to obtain the desired shape, size and surface quality. Milling is mostly done using milling machines, which include horizontal milling machines, vertical milling machines, gantry milling machines, profile milling machines, universal milling machines and lever milling machines.

[0003] When milling glass molds, some of the molds are small in size, so high-precision CNC milling machines are required. However, existing CNC milling machines can only process one side of the mold and cannot adjust the mold angle. When performing some chamfering, the effect can only be achieved by cutting the corner multiple times, which is time-consuming and laborious, and the effect is not perfect. Utility Model Content

An angle component is provided on the top of the linkage ring 8, and an orientation component is provided on the support column 6.

[0024] In this embodiment, the orientation component includes a rotating base 10 and a rotating servo motor 11. The rotating base 10 is rotatably mounted on the top of the support column 6. The support column 6 has an internal receiving groove. The rotating servo motor 11 is fixedly mounted on one inner wall of the receiving groove. The output shaft of the rotating servo motor 11 is fixedly connected to the rotating base 10. The rotating base 10 can be rotated by the rotating servo motor 11, thereby adjusting the orientation of the tray 16 and the mold.

[0025] In this embodiment, the angle assembly includes an inner groove ring 9, an angle shaft 12, a ball head rod 13, and an L-shaped base 14. The inner groove ring 9 is fixedly installed on the top of the linkage ring 8. The angle shaft 12 is rotatably passed through one side of the rotating base 10. The ball head rod 13 is fixedly installed at one end of the angle shaft 12. The ball head of the ball head rod 13 is slidably installed in the inner groove of the inner groove ring 9.

[0026] In this embodiment, the limiting mechanism includes a limiting base 17, a driving component, two limiting sliders 20, and a limiting clip 21.

[0028] Working principle: In use, the operator first places the mold on the tray 16, then starts the CNC milling machine 1 via the main control computer. The CNC milling machine 1 seals the internal processing chamber, and then starts the limit servo motor 18. The limit servo motor 18 drives the forward and reverse thread ball screw 19 to rotate. The rotation of the forward and reverse thread ball screw 19 drives the two limit sliders 20 to move. The movement of the two limit sliders 20 causes the corresponding limit clamps 21 to move closer to each other, clamping the mold. Then, the CNC milling machine 1 starts the milling cutter 5 to process the mold according to the preset program. During processing, the movement servo motor 4 can drive the ball screw 3 to rotate, thereby driving the movement servo motor 5 to rotate the milling cutter 5. The base 2 moves to adjust the lateral position of the mold. The electric push rod 7 drives the linkage ring 8 to move, which in turn drives the inner groove ring 9 to move. The ball head of the ball rod 13 is slidably installed on the inner side of the inner groove ring 9. An angle shaft 12 is fixedly installed at the other end of the ball rod 13. The angle shaft 12 rotates through the rotating base 10. The inner groove ring 9 moves up and down, causing the ball rod 13 to tilt, which in turn causes the L-shaped base 14 to tilt, thereby causing the tray 16 and tray support 15 to tilt. The angle of the mold can be adjusted. At the same time, the rotating base 10 can be rotated by rotating the servo motor 11, thereby adjusting the orientation of the mold, which makes it easier for the milling cutter 5 to perform more precise and detailed processing on the mold.

[0029] The technological advancement of this invention compared to the prior art is that the mold can be clamped and limited first, and then its orientation and angle can be adjusted to facilitate the milling cutter 5 to process the mold, making the mold processing more convenient and faster. At the same time, it can also improve the processing effect of some irregular molds and increase the utilization effect of the equipment.
