Description

Technical Field

[0001] The present invention relates to the technical field of glasses processing, in particular to a slot milling machine tool for processing glasses legs. Background Art

[0002] During the temple processing process, a machine tool is required to mill the temples to form slots for installing the hinge seat. The metal clamps on the processing table are then clamped from the side to fix the temples with the front end facing upward, and the milling cutter head is moved for processing. When fixing the temples for processing, in order to prevent the hard metal clamps from crushing the temples during the tightening process, softer plastic plates are usually used. After slotting, they are pieced together from both sides of the temples to act as an intermediary for the metal clamps to clamp the temples and protect them during the milling process. However, due to the different widths of temples for different types of glasses, the temple processing process requires repeated processing of different plastic plates, machining slots on the plastic plates that match the width of the temples to avoid deviations in the milling slots caused by tilting when fixing the temples. Therefore, designing a milling machine tool for temple processing that can tighten temples of different widths and is less prone to deviation has become a technical problem that urgently needs to be solved. Summary of the Invention

[0005] After adopting the above structure, the metal splint drives the plastic splint to open and close, the temples are aligned with the temple grooves on the plastic splint, the plastic splints are spliced ​​together to clamp the temples from both sides to complete the fixation, and the temples are processed by the milling cutter head; by removing the positioning pins connected between the metal splint and the plastic splint, the pair of plastic splints are rotated synchronously by using the steering shaft to exchange the positions of the wide groove and the narrow groove, the positioning pins are reinstalled to fix the position of the plastic splint relative to the metal splint, and the milling cutter head is aligned with different slots to clamp temples of different widths more stably without the need for re-spinning. Reprocess and replace different plastic splints into the metal splint; set an intersection point corresponding to the position of the steering shaft through the wide groove and the narrow groove. When the plastic splint is rotated around the steering shaft and the wide groove and the narrow groove are exchanged, the mirror foot and the milling cutter head will not be misaligned, preventing the milling accuracy from being reduced; realize the disassembly and assembly of the positioning pin, operate the plastic splint to rotate synchronously around the steering shaft, and there is no need to replace the plastic splint. It is more convenient to align the mirror foot slots of different widths with the milling cutter head, clamp the mirror foot in the mirror foot slot with matching width, and the mirror foot is not easy to tilt, avoiding errors in milling the mirror foot.

[0007] After adopting the above structure, the positioning pin is installed by inserting one end of the positioning pin through the latch hole and into any positioning hole, and vice versa for removal; since the positioning holes are arranged at equal angles around the circumferential direction of the steering shaft, it is easier to align the positioning holes with the latch holes according to the rotation angle of the plastic splint.

[0008] As a further improvement of the present invention, the end of the positioning pin is provided with a raised arc-shaped guiding surface.

[0009] With the above structure, a raised arc-shaped guide surface is provided at the end of the positioning pin, and the arc-shaped guide surface contacts the ends of the plug through hole and the positioning hole, making it easier to guide the positioning pin to be inserted into the two.

[0010] As a further improvement of the present invention, the positioning holes and the mirror foot grooves are staggered in the circumferential direction around the steering axis.

[0011] With the above structure, the positioning holes and the mirror foot grooves are staggered around the circumferential direction of the steering axis, thereby avoiding multiple missing plastic splints at the same position, improving the structural strength of the plastic splint and extending its service life.
