Abstract
The utility model discloses an automatic-focusing optical path transmission device for a laser processing device, which comprises a laser placed on an X shaft, goggles arranged on the crossing point of the X shaft and the Y shaft, a laser cutting head mounted in the Z shaft direction, and a focusing mirror arranged in the laser cutting head. The automatic-focusing optical path transmission device is characterized in that a self-adapting reflecting mirror is arranged on the crossing point of the Y shaft and the Z shaft, a pneumatic adjusting device is arranged on the self-adapting reflecting mirror, light beams emitted out by the laser are towards the Y shaft direction after being reflected by a flat mirror, and is vertically steered to the laser cutting head after being reflected by the self-adapting reflecting mirror, and is focused by the focusing mirror. The transmission device has simple structure, convenient control and operation, strong practicability and low manufacture cost, and is easy to assemble and debug, and greatly improves production efficiency. The position of a laser focal point is on one third of the thickness of a steel plate when cutting steel plates with different thickness, and best cutting effect can be reached.
Description
Technical field
The utility model relates to a kind of laser process equipment automatic focusing optic path device, is mainly used in laser cutting device.
Background technology
Laser processing technology be meant adopt high energy laser beam to material or piece surface cut, the process engineering of welding, mark, engraving, surface treatment and microfabrication etc.The system of Laser Processing is made up of five parts usually at least, i.e. laser instrument, light-conducting system, laser process equipment body, Laser Processing head unit and processing workbench.Wherein, light-conducting system is the indispensable parts that the laser beam that laser instrument sends are delivered to the Laser Processing head unit, because laser beam is not parallel, when the Laser Processing head unit is mobile on plant equipment, the diameter of light beam is changing, therefore, laser beam is delivered to the Laser Processing head unit accurately and realizes Laser Processing, be the function of light-conducting system indispensability, so the performance of light-conducting system directly influences the quality of Laser Processing.
At present, the light-conducting system function constantly strengthens, and not only can transmit laser beam, adjusts simultaneously, and can realize functions such as the expansion bundle to laser beam, compensation with a tight waist, still there is not method preferably but adjust effective focal length how safely, conveniently, accurately.
The utility model content
In view of this, the technical problems to be solved in the utility model is to provide and is provided with self-adapting reflection mirror and focuses automatically, when realizing cutting the different-thickness steel plate simultaneously, focuses automatically, thereby reaches good cutting effect.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of laser process equipment automatic focusing optic path device, comprise and be positioned over laser instrument on the X-axis, be positioned at X, goggles on the Y direction intersection point, be installed in the laser cutting head on the Z-direction and be located at the interior focus lamp of this laser cutting head, at Y, the intersection point of Z axle is provided with self-adapting reflection mirror, self-adapting reflection mirror is provided with the pneumatic type adjusting device, light beam that laser instrument sends through the level crossing vertical reflection after to Y direction, pass through the laser cutting head of vertical duction Z-direction after the reflection of self-adapting reflection mirror again, the line focus mirror focuses on.
Described goggles is installed on the crossbeam of Y-axis by microscope base.
Described self-adapting reflection mirror is fixed on the Z axle box by microscope base.
The technique effect that the utility model reaches is as follows:
1, transmitting device of the present utility model is simple in structure, control operation convenient, practical, low cost of manufacture, be easy to the assembling and setting operation, enhances productivity greatly.It has been used for actual industrial production, and result of use is very good and obtained good economic benefit.
2, the light path of transmitting device of the present utility model is before being transferred to laser cutting head, utilize the self adaptation of self-adapting reflection mirror dynamic beam waist, thereby realize the variation of effective focal length, focus lamp is also fixed to the distance of cutting head so focus on the laser spot of coming out to the variation of the distance of cutting head in the laser cutting head.In cutting different-thickness steel plate, allow the seat of laser spot in the position of steel plate thickness 1/3, can both reach best cutting effect.
Description of drawings
Fig. 1 is the structural representation of the utility model transmitting device;
Fig. 2 is the optic path schematic diagram of the utility model transmitting device.
The specific embodiment
As Fig. 1-shown in Figure 2, be laser process equipment automatic focusing optic path device of the present utility model, comprise be positioned over laser instrument 1 on the X-axis, be positioned at X, the goggles 2 on the Y direction intersection point, the focus lamp 4.1 that is installed in the laser cutting head 4 on the Z-direction and is located at this laser cutting head 4, on the intersection point of Y, Z axle, be provided with self-adapting reflection mirror 3, the pneumatic type adjusting device is housed on the self-adapting reflection mirror 3; Servo valve on the pneumatic regulation unit receives the cut workpiece thickness information that the sensor on the laser cutting head transmits, and regulates control voltage, thereby changes the air pressure in the mirror chamber, to change the concavo-convex angle of eyeglass; Light beam that laser instrument 1 sends to Y direction, passes through vertical duction laser cutting head 4 after the reflection of self-adapting reflection mirror 3 through level crossing 2 reflection backs again, and line focus mirror 4.1 focuses on.Light path was utilized the self adaptation of self-adapting reflection mirror 3 dynamic beam waists before being transferred to laser cutting head 4, thereby realized the variation of effective focal length.
The goggles 2 of present embodiment is installed in by microscope base on the crossbeam of Y-axis, and self-adapting reflection mirror 3 is fixed on the Z axle box by microscope base.
As shown in Figure 2, be the utility model device optic path system schematic, the laser beam 5 that laser instrument 1 sends laterally is diverted to Y direction through X-direction through mirror 2 levels of redressing, be diverted to laser cutting head 4 downward vertically through self-adapting reflection mirror 3 again, the focus lamp 4.1 in laser cutting head 4 focuses on.Because laser beam has the minimum characteristic of short distance diffusion, thus crossbeam along back timber move left and right X-axis and laser cutting head 4 when crossbeam moves forward and backward Y-axis, all can not influence the energy of laser beam, thereby guarantee cut quality.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
