[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The present invention discloses a positioning drilling device for processing flexible metal mirror temples, comprising a processing table 1, a lifting component 2 above the processing table 1, a motor 3 at the output end of the lifting component 2, a drill bit 4 at the output end of the motor 3, and a switch 5 on the processing table 1, the switch 5 being connected to the lifting component 2 and the motor 3 respectively via electrical signals.

[0025] The upper end of the processing table 1 is provided with a clamping table 6. Two clamping blocks 8 and a sliding groove 7 are symmetrically arranged on the clamping table 6. The lower end of the clamping block 8 is provided with a slider 9 that slides in cooperation with the sliding groove 7. A rotating shaft is rotatably arranged on the clamping table 6. One end of the rotating shaft is provided with a toggle block 11. Two screws 10 with reverse thread structure are symmetrically arranged on the rotating shaft. The two screws 10 pass through the two sliders 9 respectively and are threadedly connected to the sliders 9.

[0026] In this embodiment, a support plate 12 is fixedly installed at the upper end of the processing table 1, a guide groove 14 is provided at the lower end of the clamping table 6, and a guide rail 15 inserted into the guide groove 14 is provided at the upper end of the support plate 12. The clamping table 6 and the support plate 12 are slidably engaged. A limiting frame 16 is fixedly installed in the middle part of the support plate 12. The limiting frame 16 is located on one side of the clamping table 6, and a locking rod 17 is provided on the limiting frame 16. The locking rod 17 passes through the limiting frame 16 and contacts the clamping table 6. The locking rod 17 is threadedly connected to the limiting frame 16. The guide rail 15 has a T-shaped cross-section, which facilitates the adjustment of the position of the metal temple after clamping, thereby improving the applicability of this structure.

[0027] Clamping principle: By rotating the actuating block 11 on the rotating shaft, the rotating shaft is driven to rotate. Since the rotating shaft is provided with two symmetrical screws 10 with opposite thread structures, and the screws 10 are threadedly connected to the sliders 9, when the rotating shaft rotates, the two screws 10 will drive the sliders 9 connected to them to slide in opposite directions or back to back in the sliding grooves 7 of the clamping table 6, thereby realizing the clamping or loosening action of the two clamping blocks 8 on the flexible metal temple, and stably fixing the drilled part of the metal temple on the clamping table 6.

[0028] Drilling principle: After the metal temple is clamped and fixed, operate switch 5 on the processing table 1 to control the lifting component 2 (telescopic cylinder) to extend downward, driving the motor 3 and the drill bit 4 at the output end of the motor 3 to descend to the position of the metal temple to be drilled. Then, start the motor 3 again through switch 5. The motor 3 drives the drill bit 4 to rotate at high speed to drill the metal temple. After drilling is completed, operate switch 5 again to raise the lifting component 2, driving the drill bit 4 away from the metal temple, completing one drilling operation.

[0029] Position adjustment principle: When the position of the clamping table 6 needs to be adjusted, loosen the locking rod 17 on the limit frame 16 to release the fixed state between the clamping table 6 and the limit frame 16. At this time, the clamping table 6 can be pushed to slide on the guide rail 15 of the support plate 12. The cross section of the guide rail 15 is T-shaped, which cooperates with the guide groove 14 at the lower end of the clamping table 6 to ensure the stability and straightness of the sliding of the clamping table 6. After adjusting the position, tighten the locking rod 17 so that the locking rod 17 abuts against the clamping table 6 and fixes the clamping table 6 in the appropriate position.

[0030] 1) Installing the temples: Rotate the actuating block 11 to move the two clamping blocks 8 in opposite directions, place the flexible metal temples in a suitable position between the two clamping blocks 8, rotate the actuating block 11 again to move the two clamping blocks 8 towards each other, clamp the metal temples, and use the anti-slip texture on the inside of the clamping blocks 8 to increase friction and prevent the temples from sliding during processing.

[0031] 2) Adjusting the position: If the position of the metal temple needs to be adjusted, loosen the locking rod 17 on the limit bracket 16, push the clamping table 6 to slide on the guide rail 15 of the support plate 12, adjust the metal temple to the appropriate drilling position, tighten the locking rod 17, and fix the position of the clamping table 6.

[0032] 3) Drilling operation: Operate switch 5 on the processing table 1 to control the lifting component 2 (telescopic cylinder) to extend downwards, so that the drill bit 4 is lowered to the position of the metal temple to be drilled. Then press switch 5 again to start motor 3, so that the drill bit 4 rotates at high speed to drill. After drilling is completed, operate switch 5 to raise the lifting component 2, so that the drill bit 4 is lifted away from the metal temple.

[0033] 4) Remove the temple: Rotate the toggle block 11 to move the two clamping blocks 8 in opposite directions, release the clamping of the metal temple, and then remove the processed metal temple from the clamping table 6.

[0034] By clamping and fixing the flexible metal temple with two clamping blocks 8, the temple can be effectively prevented from moving during drilling, thus ensuring the accuracy of the drilling position, improving drilling precision, and avoiding inconvenience caused by drilling position deviation during later installation.

[0035] The device is relatively simple to operate. By controlling the lifting assembly 2 and the motor 3 through switch 5, drilling operations can be completed quickly. The position of the clamping table 6 can be easily adjusted to meet drilling needs in different positions, reducing the time for manual adjustment and positioning, and improving the overall processing efficiency.

[0036] The clamping table 6 can slide on the guide rail 15 of the support plate 12 and is fixed by the limit frame 16 and the locking rod 17. It can flexibly adjust the position of the metal temple and adapt to the drilling needs of flexible metal temples of different sizes and shapes, thus improving the applicability of the device.

[0037] In this embodiment, the middle part of the support plate 12 is provided with a pad 13, and the pad 13 is provided with a through hole, which can provide support for the drilled part of the metal temple and improve the stability of the metal temple during processing.

[0038] In this embodiment, the lifting assembly 2 is a telescopic cylinder.

[0039] In this embodiment, the inner side of the clamping block 8 is provided with anti-slip texture.

[0040] Good stability: The cross-section of the guide rail 15 is T-shaped, which cooperates with the guide groove 14 at the lower end of the clamping table 6 to ensure the stability and straightness of the sliding of the clamping table 6. At the same time, the pad block 13 supports the drilling of the metal temple, further improving the stability of the metal temple during processing and ensuring the smooth progress of the drilling process.

[0041] Good anti-slip effect: The inner side of the clamping block 8 is provided with anti-slip texture, which increases the friction between it and the metal temple, and can better fix the metal temple and prevent it from sliding during processing.
