Description

Technical Field

[0001] The utility model relates to the technical field of folding laser tubes, in particular to a medium-power folded tube for carbon dioxide. Background Art

[0002] The carbon dioxide folded tube, namely a glass-encapsulated and sealed CO2 laser, generates laser with a wavelength of 10.6um by high-voltage discharge to excite a high-concentration CO2 gas, and is an application for high-power laser output. Different from the combined laser tube, the folded laser tube adopts a laser waveguide structure based on bending. It places the laser rod in a Z-shaped groove with chamfers, and these grooves will guide the laser beam through a series of total reflection mirrors, gradually strengthening the laser power during the reflection process. Therefore, the folded laser tube has better performance and application advantages in terms of output power density, beam quality, stability, and lifespan.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Figure 1-6 As shown, the utility model provides a carbon dioxide medium-power folding tube, the folding tube comprises a laser tube unit 1 and a support unit 2;

[0029] The laser tube unit 1 is composed of a discharge tube, a water-cooled tube, a gas storage tube, a return air tube, a reflecting lens, a lens, and a cold cathode electrode. The gas storage tube is filled with carbon dioxide gas. Through the discharge process, the carbon dioxide gas molecules are excited, causing them to transition from a low energy state to a high energy state. Electrons are accelerated and collide with the carbon dioxide molecules, resulting in molecular excitation and the release of photons. The photons are repeatedly reflected in the resonant cavity and stimulate more carbon dioxide molecules to release photons of the same wavelength, forming a laser beam. The folding of the laser resonant optical path is achieved through the reflecting lens. After being amplified and enhanced by the resonant cavity, the laser beam is output through the lens. This is the prior art and will not be elaborated here;

[0030] The support unit 2 includes a mounting base 21, a lower support plate 22, and an upper support plate 23. The lower support plate 22 is fixedly installed on the upper surface of the mounting base 21. The upper support plate 23 is arranged above the lower support plate 22. A number of uniformly distributed semi-circular grooves 24 are formed on both the lower support plate 22 and the upper support plate 23. The laser tube unit 1 passes through the semi-circular grooves 24. Rubber pads 25 are fixedly installed on the inner walls of the number of semi-circular grooves 24. The outer tube wall of the laser tube unit 1 is in movable contact with the inner wall of the rubber pads 25. The support unit 2 supports the laser tube unit 1. Specifically, the mounting base 21 is fixedly installed on the equipment tabletop through bolts. The laser tube unit 1 passes through the semi-circular grooves 24, and the rubber pads 25 are in contact with the outer tube wall of the laser tube unit 1. After the upper support plate 23 is fixed above the lower support plate 22, support can be formed;

[0031] A splicing mechanism 3 and a pressing mechanism 4 are respectively provided on the lower support plate 22 and the upper support plate 23. By setting the splicing mechanism 3, the splicing mechanism 3 can enable a plurality of lower support plates 22 and a plurality of upper support plates 23 to be spliced together, avoiding the installation of a plurality of mounting bases 21 through bolts, and improving the convenience of installing a plurality of laser tube units 1. By setting the pressing mechanism 4, the pressing mechanism 4 can conveniently fix the upper support plate 23 on the lower support plate 22, improving the convenience of installation between the upper support plate 23 and the lower support plate 22;

[0032] The splicing mechanism 3 includes two internal thread sleeves 31. One of the internal thread sleeves 31 is rotatably installed at one end of the lower support plate 22, and the other internal thread sleeve 31 is rotatably installed at one end of the upper support plate 23. Threaded rods 32 are rotatably installed on the inner walls of both internal thread sleeves 31 by threads. Connecting thread sleeves 33 are fixedly installed at the other ends of the lower support plate 22 and the upper support plate 23 respectively. Notches 34 are opened at one ends of the lower support plate 22 and the upper support plate 23 respectively. Worms 35 are rotatably installed on the inner walls of both notches 34. Worm wheels 36 are fixedly installed at one ends of both internal thread sleeves 31. One of the worms 35 is meshed and connected with one of the worm wheels 36. By rotating the worm 35, the worm 35 makes the worm wheel 36 rotate, and the worm wheel 36 makes the internal thread sleeve 31 rotate. The self-rotation of the internal thread sleeve 31 makes the threaded rod 32 rotate and move by threads. When the two lower support plates 22 or the two upper support plates 23 are horizontally corresponding, the threaded rod 32 is horizontally corresponding to the connecting thread sleeve 33. The threaded rotation and movement of the threaded rod 32 can enter the connecting thread sleeve 33, and thus the quick splicing of the two lower support plates 22 or the two upper support plates 23 can be realized. A knob 37 is fixedly installed at one end of one of the worms 35. By manually rotating the knob 37, the knob 37 can make the worm 35 rotate. A tapered rod 38 is fixedly installed at the other end of one of the worms 35. A tapered groove 39 is opened at one end of the other worm 35. The tapered rod 38 and the tapered groove 39 are in interference fit. By setting the tapered rod 38 and the tapered groove 39, after the upper support plate 23 is fixed above the lower support plate 22, the tapered rod 38 is vertically inserted into the tapered groove 39, and the tapered rod 38 is in interference fit with the tapered groove 39 by its own elasticity. When the worm 35 on the upper support plate 23 rotates, the worm 35 on the lower support plate 22 rotates synchronously.

[0033] The pressing mechanism 4 includes two lengthened screws 41. Two grooves 42 are opened on the upper support plate 23. One of the lengthened screws 41 is rotatably installed in one of the grooves 42 by threads. Two threaded holes 43 are opened on the lower support plate 22. One end of one of the lengthened screws 41 is threadedly and rotatably connected with the inner wall of one of the threaded holes 43. By rotating the lengthened screw 41, when the lengthened screw 41 enters the inside of the threaded hole 43, the upper support plate 23 can be fixed on the lower support plate 22. Fixed disks 44 are fixedly installed at the other ends of both lengthened screws 41. Hexagonal rotating seats 45 are fixedly installed on one side of both fixed disks 44. By setting the fixed disks 44 and the hexagonal rotating seats 45, it is convenient for the operators to rotate the lengthened screws 41.

[0034] Working principle: During the support process of the laser tube unit 1, the operator first installs the mounting base 21 on the equipment platform through bolts, then places the laser tube unit 1 in the three semi-circular grooves 24 of the lower support plate 22. Subsequently, the upper support plate 23 is placed above the lower support plate 22, and the two hexagonal rotating seats 45 are rotated respectively. The two hexagonal rotating seats 45 drive the two lengthened screw rods 41 to rotate through the two fixed disks 44, and the two lengthened screw rods 41 are threaded into the corresponding threaded holes 43 (during this process, the tapered rod 38 is vertically inserted into the tapered groove 39 and forms an interference fit). At this time, the upper support plate 23 is fixed on the lower support plate 22, thus conveniently realizing the fixed installation of the laser tube unit 1, and effectively improving the convenience of the installation of the laser tube unit 1;

[0035] When multiple laser tube units 1 need to be installed side by side, the operator horizontally aligns the two support units 2 (refer to Figure 6 ), then manually rotates the knob 37. The knob 37 rotates a corresponding worm 35. A worm 35 drives another worm 35 to rotate synchronously and in the same direction through the tapered rod 38 and the tapered groove 39. The two worms 35 drive the two worm wheels 36 to rotate. The two worm wheels 36 drive the two internally threaded sleeves 31 to rotate. The self-rotation of the two internally threaded sleeves 31 causes the two threaded rods 32 to rotate and move in a threaded manner. The threaded rotation and movement of the two threaded rods 32 enter the corresponding connecting threaded sleeves 33 to form a threaded connection, thereby realizing the rapid splicing of the two lower support plates 22 and the two upper support plates 23. Then, the installation of other laser tube units 1 can be completed according to the above operation steps, thus conveniently realizing the rapid splicing of the support unit 2, avoiding the installation of the mounting bases 21 of multiple support units 2 through bolts, and effectively improving the convenience of the installation of multiple laser tube units 1.

[0036] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these modifications and variations.
