Description
Technical Field
[0001] The utility model relates to the technical field of glass fixtures, and particularly relates to a fixture for processing optical glass. Background Technique
[0002] Optical glass refers to circular glass with transparency, refractivity and reflectivity, and is usually used in optical instruments, optical instruments and optical manufacturing. Optical glass is often used to manufacture optical components such as optical lenses, optical lenses and optical lens holders. When processing optical glass, it is necessary to polish it to ensure the transparency of the glass, so a fixture for processing optical glass is needed to fix it.
[0003] At present, when the edge of optical glass is polished at the edge grinding machine, an optical glass edge grinding fixture is installed at the opposing top seat of the edge grinding machine, and the optical glass is clamped by the optical glass edge grinding fixture for edge grinding. After the edge grinding fixture clamps and grinds the optical glass, the edge grinding fixture usually separates oppositely at the edge grinding machine. At this time, the worker needs to hold the optical glass with his hand in advance, otherwise the optical glass will directly fall on the machine table of the edge grinding machine and be damaged. When the worker operates the holding of the optical glass edge grinding for a long time, it is easy to have a holding error, resulting in damage to the optical glass. For this reason, we propose a fixture for processing optical glass. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a fixture for processing optical glass. T-shaped abutting rods and rubber outer suction cups are respectively improved and arranged at the main chuck of the main edge grinding fixture and the auxiliary chuck of the auxiliary edge grinding fixture. The main chuck presses against the optical glass with the T-shaped abutting rod and the rubber outer suction cup of the auxiliary chuck for clamping, which is convenient for the edge grinding of the optical glass. The main chuck and the auxiliary chuck are pulled back and separated oppositely. At this time, the spring elastically restores and the T-shaped abutting rod presses the optical glass against the rubber outer suction cup and the rubber inner suction cup for negative pressure adsorption. The optical glass will not immediately fall and break after the main chuck and the auxiliary chuck are loosened, so that the worker does not need to hold the optical glass for unloading in time, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A fixture for optical glass processing, comprising a main edging fixture and an auxiliary edging fixture, further comprising a rubber outer suction cup, a rubber inner suction cup, a stud, a spring and a T-shaped abutting rod. The heads of the main edging fixture and the auxiliary edging fixture are respectively fixed with a main chuck and an auxiliary chuck, and a disc-shaped groove is recessed on the surface of the auxiliary chuck. The rubber outer suction cup is clamped in the groove body of the disc-shaped groove, and a rubber inner suction cup is integrally formed in the middle of the rubber outer suction cup. A fastening bolt is rotatably installed between the middle parts of the rubber inner suction cup and the rubber outer suction cup and the auxiliary chuck. A concave hole is recessed in the disc body of the main chuck, and a stud is fixed at the bottom of the concave hole. A spring that is stuck outside the stud is clamped in the concave hole, and a T-shaped abutting rod is welded to the outer circumferential surface of the spring away from the stud.
[0007] Further, the tail part of the spring is rotatably stuck on the outer column body of the stud;
[0008] By adopting the above technical solution, the spring can be rotatably stuck at the stud, so that the spring is not easily disengaged from the concave hole.
[0009] Further, the disc body of the rubber outer suction cup exposes the notch of the disc-shaped groove;
[0010] By adopting the above technical solution, the disc body of the rubber outer suction cup can expose the disc-shaped groove to contact with the optical glass for adsorption.
[0011] Further, the diameter of the hole cavity of the installation hole is the same as the diameter of the spring coil;
[0012] By adopting the above technical solution, the spring can bounce along the hole cavity in the installation hole.
[0013] Further, the tail end of the rod body of the T-shaped abutting rod is welded inside the spring, and a disc-shaped rod block extends from the head of the rod body of the T-shaped abutting rod towards the auxiliary chuck;
[0014] By adopting the above technical solution, after the T-shaped abutting rod is fixed by welding the rod tail at the spring, the T-shaped abutting rod can press the optical glass against the rubber outer suction cup with the disc-shaped rod block.
[0015] Further, an installation hole is provided between the middle parts of the rubber inner suction cup and the rubber outer suction cup and the auxiliary chuck, and a fastening bolt is rotatably connected in the installation hole;
[0016] By adopting the above technical solution, the installation holes of the rubber inner suction cup and the rubber outer suction cup and the auxiliary chuck can be rotatably connected with fastening bolts for installation.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] In the present utility model, by respectively improving and arranging a T-shaped abutting rod and a rubber outer suction cup at the main chuck of the main grinding-edge fixture and the auxiliary chuck of the auxiliary grinding-edge fixture, the main chuck presses against the optical glass with the T-shaped abutting rod and the rubber outer suction cup of the auxiliary chuck for clamping, which facilitates the grinding of the optical glass. The main chuck and the auxiliary chuck are pulled backward and separated from each other. At this time, the spring elastically restores, and the T-shaped abutting rod abuts the optical glass against the rubber outer suction cup and the rubber inner suction cup for negative pressure adsorption. The optical glass will not immediately fall off after the main chuck and the auxiliary chuck are loosened, so that the worker does not need to immediately hold the optical glass for unloading;
[0019] Moreover, there is an additional pushing, abutting and sucking clamping structure between the main chuck of the main grinding-edge fixture and the auxiliary chuck of the auxiliary grinding-edge fixture, so that the optical glass maintains a stable clamping state when being clamped oppositely, effectively ensuring that the optical glass can be clamped for grinding processing.

The heads of the main edge grinding fixture 1 and the auxiliary edge grinding fixture 2 are respectively fixed with a main chuck 3 and an auxiliary chuck 4. A disc-shaped groove 5 is recessed on the surface of the auxiliary chuck 4. A rubber outer suction cup 6 is clamped in the groove body of the disc-shaped groove 5, and a rubber inner suction cup 7 is integrally formed in the middle of the rubber outer suction cup 6. A fastening bolt 9 is screwed and installed between the middle parts of the rubber inner suction cup 7 and the rubber outer suction cup 6 and the auxiliary chuck 4. A concave hole 10 is recessed on the disc body of the main chuck 3, and a stud 11 is fixed at the bottom of the concave hole 10. A spring 12 clamped outside the stud 11 is clamped in the concave hole 10, and a T-shaped abutting rod 13 is welded to the outer circumferential surface of the spring 12 away from the stud 11.
[0027] Among them, the tail spring body of the spring 12 is screwed on the outer column body of the stud 11;
[0028] By adopting the above technical solution, the spring 12 can be screwed on the stud 11, so that the spring 12 is not easily disengaged from the concave hole 10.
[0029] Among them, the disc body of the rubber outer suction cup 6 exposes the notch of the disc-shaped groove 5;
[0030] By adopting the above technical solution, the disc body of the rubber outer suction cup 6 can expose the disc-shaped groove 5 to contact the optical glass for adsorption.
[0031] Among them, the diameter of the hole cavity of the mounting hole 8 is the same as the diameter of the spring coil of the spring 12;
[0032] By adopting the above technical solution, the spring 12 can bounce along the hole cavity in the mounting hole 8.
[0033] Among them, the tail end of the rod body of the T-shaped abutting rod 13 is welded inside the spring 12, and a disc-shaped rod block extends from the head of the rod body of the T-shaped abutting rod 13 towards the auxiliary chuck 4;
[0034] By adopting the above technical solution, after the T-shaped abutting rod 13 is fixed by welding the rod tail to the spring 12, the T-shaped abutting rod 13 can press the optical glass against the rubber outer suction cup 6 with the disc-shaped rod block.
[0035] Among them, a mounting hole 8 is opened between the middle parts of the rubber inner suction cup 7 and the rubber outer suction cup 6 and the auxiliary chuck 4, and a fastening bolt 9 is screwed in the mounting hole 8;
