Description

Clamp for laser cutting of glasses

Technical Field

The utility model relates to a glasses processing technology field, concretely relates to anchor clamps are used in glasses laser cutting.

Background

Laser cutting utilizes high-power-density laser beams to irradiate a cut material, so that the material is heated to a vaporization temperature quickly and is evaporated to form holes, and the holes continuously form slits with narrow width (such as about 0.1 mm) along with the movement of the laser beams to the material, so that the material is cut.

In the production of glasses, some metal frames and temples are formed by cutting on a thin steel plate directly by laser. In order to reserve more workable area of the steel plate as much as possible, only the edge of the steel plate is clamped during clamping.

Among them are the problems: due to the adoption of the thin steel plate, the steel plate is easy to bulge when being clamped and fixed, and the size of a product cut by laser is deviated.

In addition, in order to utilize raw materials as much as possible, some steel plates are irregular leftover materials, the shapes of the steel plates are complicated and changeable, and common clamps are difficult to clamp effectively.

The device comprises a 1-infrared transmitter, a 2-infrared receiver, a 3-left chuck, a 4-right chuck, a 31-bearing seat, a 32-lower pressing plate, a 33-driving cylinder, a 34-guiding shaft, a 35-first sliding hole, a 41-optical axis, a 42-screw, a 43-through hole, a 44-screw hole, a 45-hand wheel, a 5-folding arm, a 52-pressing end face, a 53-caulking groove and a 54-second sliding hole.

Detailed Description

As shown in fig. 1-4, a fixture for laser cutting of glasses comprises an infrared emitter 1, an infrared receiver 2, a left chuck 3 and a right chuck 4, wherein each of the left chuck 3 and the right chuck 4 comprises a support base 31, a lower pressing plate 32 and a driving cylinder 33, the support base 31 is provided with a guide shaft 34 along a vertical direction, the lower pressing plate 32 is provided with a first sliding hole 35 adapted to the guide shaft 34, the guide shaft 34 is sleeved with the first sliding hole 35 for axial sliding fit, the driving cylinder 33 is fixedly connected to the support base 31 and is in linkage fit with the lower pressing plate 32, the support base 31 and the lower pressing plate 32 of the left chuck 3 are respectively provided with the infrared emitter 1 on one side end surface facing the right chuck 4, and the support base 31 and the lower pressing plate 32 of the right chuck 4 are correspondingly provided with an infrared receiver 2 on one side end surface facing the left chuck 3.

Utilize left chuck 3, right chuck 4 to clip the steel sheet both ends respectively and fix, when the centre gripping mode is improper, appear the steel sheet uplift or when recessed, the steel sheet deformation position blocks the infrared ray, and infrared receiver 2 can not receive the signal, sends out the police dispatch newspaper, reminds operating personnel.

The fixture further comprises an optical axis 41 and a screw rod 42, the bearing seat 31 is provided with a through hole 43 and a screw rod hole 44 along the horizontal direction, the screw direction of the screw rod hole 44 of the left chuck 3 is opposite to that of the screw rod hole 44 of the right chuck 4, the optical axis 41 is inserted into the through hole 43 to be in sliding fit, the screw rod 42 is inserted into the screw rod hole 44 to be in threaded hole fit, and the screw rod 42 is provided with a hand wheel 45.

After the operator knows that the steel plate is clamped and deformed through infrared alarm, the screw rod 42 drives the left chuck 3 and the right chuck 4 to be away from each other, so that the steel plate is leveled. Therefore, fine adjustment can be completed without starting the lower pressing plate 32, and time wasted by secondary clamping is avoided.

The clamp further comprises a folding arm 5, a second sliding hole 54 is formed in the folding arm 5 and is aligned with the guide shaft 34, the end face, contacting materials, of the bearing seat 31 and the lower pressing plate 32 is a pressing end face 52, an embedding groove 53 is formed in the pressing end portion of the bearing seat 31 and the lower pressing plate 32, the guide shaft is located in the embedding groove 53, the second sliding block sleeve of the folding arm 5 is rotatably matched with the guide shaft 34 in a sleeved mode, and the folding arm 5 is matched with the embedding groove 53 in shape and is flush with the pressing end face 52.

When the irregular steel plate leftover materials are adopted for processing, the left chuck 4 and the right chuck 4 which are arranged only can clamp a small part of the steel plates, and the clamping state is not stable, so that the folding arms 5 which can rotate around the guide shafts to turn out the caulking grooves 53 can actively extend to the irregular steel plates through the folding arms 5, and the steel plates can be synchronously clamped by utilizing the linkage relation of the folding arms 5, the bearing seats 31 and the lower pressing plates 32. Therefore, the left and right chucks 4 can adapt to irregular materials and can actively increase clamping positions.

The caulking grooves 53 are arranged at two ends of the bearing seat 31 and the lower pressing plate 32, and the folding arms 5 are arranged in each caulking groove 53.

And the pressing end face 52 is paved with an anti-skid pad.
