The utility model discloses combine laser transmission technique and accurate motion system, adopt the utility model discloses can make lathe workspace big relatively and workable large-scale complicated work piece.
Description
Technical field
The utility model relates to laser processing technology, and specifically a kind of novel two-freedom rotates laser light path transmission structure, and it makes Laser Processing more flexible.
Background technology
At present along with CO
2The laser instrument cost performance improves gradually, and powerful laser process equipment adopts CO more
2Laser generator.In order to guarantee the stable of beam quality, most laser process equipments all are to adopt fixing laser optical path.When the processed complex part, the workbench of the lathe one general configuration 2-3 free degree.The lathe working space of this form is less relatively, be difficult to realize large-scale workpiece processing, make laser flexible flexibly processed edge fully do not show.Realize the laser three-D processing flexibility, must adopt moving optical system.CO
2The transmission of laser can not be used optical fiber, can only realize by the mirror group.In moving optical system, owing to laser beam is variation campaign along with Working position, the Energy distribution of laser beam and the variation of focus characteristics can influence process.How to resolve the high power laser system of processing the transmission of laser beam with focus in the problem that exists, be the prerequisite of carrying out three-dimensional laser processing.The laser head that has two rotational freedoms can be adjusted the direction of laser beam at three dimensions, both can realize 5 interlock Laser Processings after same X, Y, the combination of Z rectilinear motion.At present, the laser head structure with two rotational freedoms yet there are no report at home, and like product is external import.
The utility model content
For the lathe working space that solves in the prior art fixing laser optical path form less relatively, be difficult to realize the deficiency of large-scale workpiece processing, but providing, the purpose of this utility model a kind ofly rotates laser light path transmission structure at the two-freedom that keeps the lathe working space relative to big and machining large complex part, it combines Laser Transmission technology and precise motion system, forms one of core technology of 5 interlock laser process machines.
The technical scheme that its technical problem that solves the utility model adopts: form by frame, first rotating shaft, mirror unit, speculum, second rotating shaft, reflect focalization microscope base, reflect focalization mirror, wherein speculum is installed on first rotating shaft, is arranged in the light path of incoming laser beam by mirror unit, the reflect focalization mirror is installed on second rotating shaft by the reflect focalization microscope base, is positioned on the light path vertical with the laser beam of incident; Frame is installed on the lathe;
Wherein: described speculum and the installation at 45 of first rotating shaft, the reflect focalization mirror and second rotating shaft coaxle are installed; Described speculum adopts level crossing; The reflect focalization mirror adopts parabolic lens; First rotating shaft is connected with the output shaft of motor by transmission device respectively with second rotating shaft; Described mirror unit is installed around the frame central rotary type; The reflect focalization microscope base is installed around mirror unit center rotary type.
The utlity model has following advantage:
1. the utlity model has two rotational freedoms, promptly first rotating shaft rotates around the central shaft of mirror unit around the central shaft rotation and second rotating shaft of frame.Adopt the utility model that Laser Transmission technology and precise motion system are combined, can be when keeping the lathe working space big relatively machining large and complicated workpiece, can guarantee stablizing of beam quality, given full play to the advantage of Laser Processing.
2. because the transmission that laser only is responsible in load is not born by the utility model mechanism itself, and therefore this is simple and compact for structure, and volume is little, in light weight, movement velocity is fast, positional precision is high and the little energy consumption that reduced of power of motor.
3. the utility model structural design modularization can assemble flexibly, adjust.Described mirror unit and reflect focalization microscope base are modular, and demolition, installation are flexible.Eyeglass is installed in the microscope base and has a style of one's own, and safeguards, debugging is convenient and simple, does not interfere with each other in other structures.
4. because modular design adopts the utility model can make the light path adjustment process simply effective.But the mirror unit and first rotating shaft, reflect focalization microscope base and the second rotating shaft delamination need be finely tuned microscope base successively following of the prerequisite that has guaranteed the frame for movement precision, will adjust to through the light beam of speculum and reflect focalization mirror and require the position.
5. with respect to the multifreedom motion workbench, the utility model structure low cost of manufacture.
Description of drawings
Fig. 1 is the utility model structure diagram.
The specific embodiment
Of the present utility model being described in detail as follows:
The utility model is made up of frame 1, first rotating shaft 2, mirror unit 3, speculum 4, second rotating shaft 5, reflect focalization microscope base 6, reflect focalization mirror 7, and wherein 8 are the laser beam of incident.First rotating shaft 2 rotates installation around the central shaft of frame 1; Mirror unit 3 is installed on first rotating shaft 2; Speculum 4 is installed in the mirror unit 3, and is at 45 with first rotating shaft; Second rotating shaft 5 rotates installation around the central shaft of mirror unit 3; Reflect focalization microscope base 6 is installed on second rotating shaft 5; Reflect focalization mirror 7 is installed in the reflect focalization microscope base 6, with second rotating shaft coaxle; Frame 1 is installed on the lathe.
Entire mechanism has two rotational freedoms.Promptly first rotating shaft 2 rotates around the central shaft of mirror unit 3 around the central shaft rotation and second rotating shaft 5 of frame 1.First rotating shaft 2 and second rotating shaft 5 pass through actuator drives by servomotor respectively.
Laser is by CO
2Send with first rotating shaft 2 coaxially after laser instrument emits through speculum, laser beam at first enters mirror unit 3 and incides on the speculum 4 with 2 placements at 45 of first rotating shaft, and is coaxial with second rotating shaft 5 after reflecting 90 °.Laser beam enters reflect focalization microscope base 6 along second rotating shaft 5.The reflect focalization mirror 7 that is installed in the reflect focalization microscope base 6 is parabolic lens, and it and the 5 coaxial installations of second rotating shaft focus on Working position after incoming laser beam can being reflected 90 ° simultaneously.Mirror unit 3 and reflect focalization microscope base 6 rotate in company with first rotating shaft 2 and second rotating shaft 5, and laser focus point realizes the three-dimensional processing of laser promptly along with motion.
