Description

Technical Field

[0001] This utility model belongs to the field of optical axis machining technology, and specifically relates to an optical axis machining drilling device. Background Technology

[0002] Optical shafts have wide applications in numerous fields. In mechanical manufacturing, they are commonly used in equipment such as cylinder rods and automatic cutting machines, serving as key components for transmitting power and motion. In optical instruments and optical communication systems, optical shafts are used to transmit optical signals; their high precision, high stability, and low loss effectively ensure the transmission quality and speed of optical signals. The manufacturing process of optical shafts typically involves drilling to allow for subsequent processing, such as mounting bearings, connectors, or other components. Different applications have varying requirements for drilling, including strict standards for hole position accuracy, depth accuracy, hole diameter tolerance, and hole wall roughness. In precision machinery, the positional accuracy of drilling may need to be controlled at a level of tens of micrometers or even higher.

[0003] During the drilling process of optical shafts, the lack of a sealing shell at the drilling location causes debris to fly in all directions. This debris may include metal shavings, abrasive particles, etc. In a machining workshop, if multiple optical shaft drilling devices are operating simultaneously, a large amount of debris will be scattered on the floor, equipment surfaces, and workbenches, making the workshop dirty and messy. This not only increases the difficulty and workload of cleaning but also affects the overall image and order of the workshop. Even when a sealing shell is present, if it is not securely tightened, gaps may appear between the sealing shells during drilling due to equipment vibration and internal pressure changes. This leads to poor sealing, and debris may still fly out from these gaps. Furthermore, a loose sealing shell also affects machining accuracy. If the sealing shell is loose during optical shaft drilling, it may cause positioning deviations in the optical shaft. Because the machining accuracy requirements for optical shafts are very high, even a small displacement can lead to non-compliance with drilling position, hole diameter, or hole perpendicularity, resulting in defective products.

[0025] A drilling apparatus for optical axis machining, comprising,

[0026] Base 1;

[0027] A snap-fit ​​sealing assembly is located on the outside of the base 1. The snap-fit ​​sealing assembly includes a sealing assembly and a snap-fit ​​assembly.

Under the combined action of the inclined surface of the telescopic block 9, the locking rod 13 can be separated from the locking groove 15.

[0038] In a specific embodiment of this utility model, the optical axis passes through the second sealing shell 4.

[0039] Working principle:

[0040] The snap-fit ​​sealing assembly confines debris inside the first sealing shell 3 and the second sealing shell 4, preventing debris accumulation in the workshop and significantly reducing the intensity and frequency of cleaning work. The snap-fit ​​sealing assembly enhances airtightness, effectively suppressing displacement caused by vibration during drilling. Debris generated during grinding may re-adhere to the optical shaft surface due to vibration, causing scratches and other defects. The snap-fit ​​sealing assembly avoids these issues, resulting in a smoother and flatter optical shaft surface.

First, the optical shaft is passed through the second sealing shell 4; the length of the optical shaft is observed; then the first motor 17 is started, and the two self-adjusting... The distance between the self-centering chucks 19 is such that both ends of the optical axis are fixed on the self-centering chucks 19 respectively. Then, the second motor 21 is started, so that the second lead screw 20 drives the punching machine body 2 to move and adjust the punching position. The punching machine body 2 is lowered, so that the lower pressure plate 8 squeezes the telescopic block 9. Under the action of the limit spring 11, the telescopic shaft 10 pushes the locking rod 13 to tilt. Since the support spring 14 supports the upper part of the locking rod 13, the locking rod 13 rotates on the rotating shaft 12, so that one end of the locking rod 13 matches the locking groove 15. At this time, the installation of the first sealing shell 3 and the second sealing shell 4 is completed. When separation is required, the locking rod 13 can be pulled outward. Under the combined action of the inclined surface of the telescopic block 9, the locking rod 13 can be separated from the locking groove 15.
