Description

A CO2 laser tube that is easy to position

Technical Field

The invention belongs to the technical field of lasers, and in particular relates to a carbon dioxide laser tube which is easy to position.

Background Art

The laser emitted by a carbon dioxide laser cannot be detected by the naked eye. It has two working modes: continuous and pulsed. It is usually used for laser cutting, welding, drilling and surface treatment. In order to achieve precise positioning, the laser is usually fixed in a fixture and then fixed to the machine body, and the laser must be installed on a horizontal or vertical surface. Due to the different appearance structures of the machines, there is a certain error in the installation position of the laser on some fixtures, which makes it difficult to ensure that the beam emitted by the laser is accurately positioned for the workpiece being processed. Therefore, the laser needs to be repositioned to ensure that the emitted beam must be parallel to the spindle tool of the processing machine.

DETAILED DESCRIPTION

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

As shown in Figures 1 to 5, the present invention is a carbon dioxide laser tube that is easy to position, including a gas storage tube 1, a discharge tube 2 arranged in the gas storage tube 1, and a water cooling tube 3 sleeved on the outside of the discharge tube 2. The gas storage tube 1 is in the shape of a long tube, and the water cooling tube 3 is sleeved on the outside of the discharge tube 2. At the same time, the water cooling tube 3 is coaxially arranged at the center of the gas storage tube 1, and the two ends of the water cooling tube 3 pass through the two ends of the gas storage tube 1 respectively. The main structure of the laser tube of the present invention adopts the existing technology, and also includes a resonant cavity part and an electrode part, wherein the gas storage tube 1 is connected to the two ends of the discharge tube 2, one end of the gas storage tube 1 has a small hole communicating with the discharge tube 2, and the other end communicates with the discharge tube 2 through a spiral gas return pipe. The technical solution of the present invention mainly describes in detail the connection device between the gas storage tube 1 and the water cooling tube 3. The connection methods and principles of the other existing structures belong to the existing technology, and those skilled in the art should be able to understand.

Specifically, in the present invention, a ball sleeve 4 is fixed on the outside of one end of the water-cooling tube 3, and a ball groove 5 is provided on the inner wall of one end of the gas storage tube 1 corresponding to the ball sleeve 4. The surface of the ball sleeve 4 can cooperate with the ball groove 5, and can achieve sealing and rotational cooperation at the same time. A first opening 6 is provided at the other end of the gas storage tube 1, i.e., the right end of FIG. 1 , and a first flexible baffle 7 is sealed and installed in the first opening 6. A center hole 8 sealed and connected to the water-cooling tube 3 is provided in the center of the first flexible baffle 7. When the water-cooling tube 3 deflects near the end where the first flexible baffle 7 is located, the water-cooling tube 3 at this location can stretch or compress the first flexible baffle 7 radially. Under the deformation adaptation of the first flexible baffle 7, it can be ensured that the first opening 6 always remains sealed. The first flexible baffle 7 of the present invention can be made of silicone material, and the center hole 8 is tightly bonded to the surface of the water-cooling tube 3.

Further, in the present invention, a plurality of radial adjustment components 9 are installed on the outer wall of the gas storage tube 1 along the circumference of the gas storage tube 1. The radial adjustment components 9 can adjust the radial position of the water cooling tube 3 at this location and support it. The radial position of the water cooling tube 3 at this location is adjusted by the radial adjustment components 9, so that the water cooling tube 3 deflects around the ball groove 5. Since the discharge tube 2 can deflect with the water cooling tube 3, the deflection angle of the light beam emitted by the laser tube can be adjusted, and the adjustment and positioning are more convenient. A torsion drive device 10 and a torsion stop device 11 for the water cooling tube 3 are also installed on the outer wall of the gas storage tube 1. By setting the torsion drive device 10, the deflected water cooling tube 3 can be further twisted around the axis of the gas storage tube 1, and the emission position of the light beam can be further controlled to meet actual needs. After twisting, the torsion stop device 11 is used to stop the water cooling tube 3 and the internal discharge tube 2 from rotating, so that the subsequent operation is more stable. After the torsion stop device 11 acts, the water cooling tube 3 remains basically stable and can be used for subsequent operations.

In this embodiment, the radial adjustment assembly 9 includes an adjustment rod 12, the middle portion of the adjustment rod 12 is threadedly connected to the tube wall of the gas storage tube 1, one end of the adjustment rod 12 extends outward and is connected to the hand-held portion 13, and the other end of the adjustment rod 12 penetrates into the gas storage tube 1 and contacts the outer wall of the water-cooling tube 3. The adjustment rod 12 extends radially along the gas storage tube 1. By rotating the adjustment rod 12, the length of the adjustment rod 12 penetrating into the inner side of the gas storage tube 1 can be adjusted, so that the gas storage tube 1 can be compressed. By adjusting and corresponding with other adjustment rods 12 in the same group, circumferential support for the water-cooling tube 3 can be achieved. The adjustment rods 12 of the present invention have two groups, each group has three adjustment rods 12, and the number of groups of adjustment rods 12 and the number of each group can be reasonably selected according to needs.

In this embodiment, the inner wall of the gas storage pipe 1 is radially inwardly protruded with a boss 14, and the center of the boss 14 is provided with a threaded hole 15 that is threadedly matched with the adjusting rod 12. The inner end of the adjusting rod 12 is fixedly connected with an arc plate 16, and the arc plate 16 is closely attached to the outer wall of the water cooling tube 3 and the curvature of the arc plate 16 is adapted to the curvature of the water cooling tube 3. By providing the boss 14, the adjusting rod 12 can be guided, so that the deepening and subsequent support of the adjusting rod 12 become more stable.

In this embodiment, the torsional drive device 10 includes a center gear 17, a rotating gear 18, a rotating bracket 19, a center shaft 20 and a second flexible baffle 21. The center gear 17 is coaxially fixed on the outside of the water-cooling tube 3. The diameter of the center gear 17 is larger than the diameter of the water-cooling tube 3, and the water-cooling tube 3 can rotate with the center gear 17. A rotating bracket 19 is rotatably provided on the outer wall of the water-cooling tube 3 on one side of the central gear 17. The hole of the rotating bracket 19 is rotatably sleeved on the outer side of the water-cooling tube 3. A central shaft 20 is fixed to one end of the rotating bracket 19. The rotating gear 18 rotates with the central shaft 20 and meshes with the central gear 17 at the same time. This ensures that the center distance between the rotating gear 18 and the central gear 17 will not be affected, and no matter how the central gear 17 deflects, it will not affect the normal meshing of the two. A second opening 22 is provided on the outer wall of the gas storage pipe 1, and the rotating gear 18 extends out of the second opening 22. A second flexible baffle 21 is installed in the second opening 22. A central hole 8 sealed and connected to the rotating gear 18 is provided in the center of the second flexible baffle 21. Similar to the sealing method of the first flexible baffle 7, when the rotating gear 18 deflects following the rotating bracket 19, the rotating gear 18 can stretch or compress the first flexible baffle 7 radially. Under the deformation adaptation of the second flexible baffle 21, it can be ensured that the second opening 22 always remains sealed. By adopting the above structure, the water cooling tube 3 can be twisted on the outside of the gas storage tube 1, which has a simple structure and is more convenient to operate.

In this embodiment, the torsion stop device 11 includes a mounting seat 23, a latch 24, an end plate 25, a spring 26, and a limit seat 27. The mounting seat 23 is mounted on the outer side of the gas storage pipe 1 by screws. A vertical channel 28 is formed in the center of the mounting seat 23, and a step 29 is formed at the lower end of the channel 28. The end plate 25 is fixed to the middle part of the latch 24, and the latch 24 is coaxially mounted in the channel 28. The end plate 25 is slidably arranged in the channel 28. A spring 26 is arranged between the end plate 25 and the mounting seat 23. The spring 26 is sleeved on the outer side of the latch 24 to provide an upward pre-tension for the end plate 25. The latch 24 is located at one end of the gas storage pipe 1 and is formed with a latch tooth 30. The latch 24 is located at one end of the gas storage pipe 1 and is connected to the limit seat 27. A slot 31 for limiting the limit seat 27 is opened on the mounting seat 23, and a rectangular plate is formed at the lower part of the limit seat 27, which can be just engaged in the slot 31. The water cooling pipe 3 is connected with a flexible water inlet pipe 32 and a flexible water outlet pipe 33 respectively, and the flexible water inlet pipe 32 is connected to the limit seat 27 through a linkage control device 34. The linkage control device 34 can drive the limit seat 27 to move up and down by the pressure of water to achieve the engagement or release of the latching tooth 30 and the central gear 17.

Specifically, in this embodiment of the present invention, the linkage control device 34 includes a hydraulic pipe 35, a piston 36, a connecting rod 37, an upper limit plate 38, a lower limit plate 39, a first linkage gear 40, a second linkage gear 41 and a connecting pipe 42. The upper end of the hydraulic pipe 35 is connected to a water pump to provide a water source with a certain pressure. The other end of the hydraulic pipe 35 is fixedly connected to the air storage pipe 1 and penetrates into the air storage pipe 1. The middle part is blocked by the piston 36. The piston 36 is slidingly sealed and arranged in the hydraulic pipe 35. The bottom of the piston 36 is connected to the latch 24 through a connecting rod 37. The lower side of the hydraulic pipe 35 is connected to the flexible water inlet pipe 32 through a connecting pipe 42. The outer side of the hydraulic pipe 35 is coaxially connected to a first linkage gear 40, and the first linkage gear 40 can be displaced along the axial direction of the hydraulic pipe 35. The outer side of the limit seat 27 is coaxially connected to a second linkage gear 41, and the second linkage gear 41 is meshed with the first linkage gear 40. An upper limit plate 38 and a lower limit plate 39 for limiting the second linkage gear 41 are respectively installed on both sides of the first linkage gear 40.

In this embodiment, an external thread 43 is provided on the outer wall of the upper end of the hydraulic tube 35, and an internal thread matching the external thread 43 is provided at the center of the first linkage gear 40. When the hydraulic tube 35 and the first linkage gear 40 are threadedly matched, the first linkage gear 40 can be driven to rotate 90°. A top limit plate 44 is also installed on the upper end of the hydraulic tube 35.

Before the device is started, there is no water flow in the water-cooling pipe 3. Under the pretension of the spring 26, the latch 24 is located at the uppermost position of the stroke. At the same time, the piston 36 connected by the connecting rod 37 is located at the uppermost end of the hydraulic pipe 35, and the lower end of the limit seat 27 is limited by the upper end of the mounting seat 23. When cold water is passed into the hydraulic pipe 35, the pressure of the cold water can act on the piston 36, causing the piston 36 to move downward. At the beginning of the movement, the second linkage gear 41 applies force to the lower limit plate 39, and the lower limit plate 39 and the upper limit plate 38 drive the first linkage gear 40 to move downward. Since the center of the first linkage gear 40 is threadedly connected to the hydraulic pipe 35, the first linkage gear 40 rotates 90° during the downward movement. Under the action of meshing, the second linkage gear 41 also rotates 90°, so that the limit seat 27 can be just inserted into the slot 31 to avoid being limited by the mounting seat 23. At this time, the limit seat 27 can move up and down normally. When the piston 36 moves to the lower end, cold water can enter the flexible water inlet pipe 32 through the lower connecting pipe 42, and then the discharge tube 2 is normally cooled. At this time, the latching teeth 30 are better engaged with the central gear 17 to prevent the central gear 17 from rotating, thereby ensuring the stability of the device operation. The device of the present invention can realize the linkage of the torsion stop device 11 through the pressure of cold water, reduce the power source, and make the structure more stable.

In this embodiment, a limiting groove 45 for limiting the rotating bracket 19 is opened on the surface of the water cooling tube 3 to prevent the rotating bracket 19 from moving in the axial direction, so that the cooperation between the rotating gear 18 and the central gear 17 is more stable.

In this embodiment, the latch 24 is threadedly connected to the limit seat 27. The length of the latch 24 extending from the limit seat 27 can be adjusted by rotating the latch 24, so that it can be adjusted according to the gas storage pipe 1 with different diameters and the accuracy can be fine-tuned to a certain extent.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
