Technical Field

The invention relates to the field of laser drilling, in particular to a laser drilling head.

Background

The existing laser drilling is basically realized by rotary cutting of a three-dimensional cutting machine tool or a three-dimensional five-axis high-end machine tool, but the three-dimensional cutting machine tool, the three-dimensional five-axis high-end machine tool and other equipment have larger occupied area and higher manufacturing and operating cost; and just because it is complicated and the size is great, it is high, the precision is lower, the uniformity is relatively poor to control the degree of difficulty when the hole that the diameter is less is processed, the degree of difficulty is higher then to process the hole that the diameter is less on complicated curved surface, the processing effect is relatively poor to this kind of equipment production efficiency is lower.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a laser punching processing head which is simple and practical, has low requirement on the precision of equipment and can improve the processing precision, consistency and efficiency.

In order to solve the technical problems, the technical scheme provided by the invention is as follows:

a laser drilling head comprises a laser swing welding head and a drilling nozzle, wherein the drilling nozzle is arranged at the end part of the laser swing welding head; the laser swing welding head is provided with a shifting device, and the shifting device drives the lens in the laser swing welding head to move.

As a further improvement of the above technical solution:

the shifting device comprises at least two shifting driving parts, the driving ends of the shifting driving parts are connected to the lenses inside the laser swing welding head, and each shifting driving part is used for driving the lenses inside the laser swing welding head to shift along different directions.

The laser drilling head further comprises a distance adjusting device, and the distance between a nozzle of the drilling nozzle and the surface to be processed is changed by adjusting the distance adjusting device.

The spray head that punches divides into two sections along its axial, distance adjusting device is including installing internal thread section and the external screw thread section on the two respectively, and the two realizes threaded connection through internal thread section and external screw thread section, distance adjusting device makes the nozzle and treats the interval change of processing surface through the coincidence region of adjusting the screw thread.

And a coaxial adjusting device is arranged on the punching spray head, and the nozzle is coaxial with the laser beam emitted by the laser swing welding head by adjusting the coaxial adjusting device.

The punching spray head is divided into two sections along the axial direction of the punching spray head, and the two sections are connected in a sleeved mode; the coaxial adjusting device comprises a plurality of adjusting bolts which penetrate through the sleeving part along the radial direction and are connected and fastened, and the adjusting bolts are uniformly distributed around the circumferential direction of the punching spray head; the coaxial adjusting device enables the nozzle to be coaxial with the laser beam emitted by the laser swing welding head by adjusting the fastening position of each adjusting bolt on the sleeve joint part.

The number of the adjusting bolts is four, and the coaxial adjusting device enables the nozzle to move along the direction by adjusting the two adjusting bolts opposite to each other in the same direction.

The punching spray head is also provided with a gas inlet which is communicated with the spray nozzle in the punching spray head.

The number of the gas inlets is not less than two, and the gas inlets are respectively used for introducing gases with different components.

Compared with the prior art, the invention has the advantages that:

the invention provides a laser punching processing head which comprises a laser swing welding head and a punching spray head, wherein the punching spray head is arranged at the end part of the laser swing welding head, and the position of the punching spray head is adjusted to enable a laser beam to be coaxial with the punching spray head. The laser swing welding head is provided with a shifting device, the shifting device drives a lens in the laser swing welding head to move, laser beams emitted by the laser swing welding head are refracted by the lens to form light spots on the surface to be processed, and the light spots can freely move due to the movement of the lens. Compared with the driving machine body which moves, the energy consumption for driving the lens is less, so that the cost and the energy are saved; and because the total drive stroke that the drive lens removed is shorter, consequently the drive precision is higher, reduces its control degree of difficulty when processing the aperture, and processing effect is good, has further improved the quality of punching.
