Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser technology, and more specifically to a carbon dioxide laser with a discharge tube support structure. Background Technology
[0002] Current carbon dioxide lasers typically include a discharge tube, a water-cooling tube surrounding the discharge tube, a gas storage tube surrounding the water-cooling tube, electrodes at both ends of the discharge tube, and output and reflection windows at both ends of the gas storage tube. The reflection window includes a reflecting mirror and a reflecting mirror cooling device, and the output window includes an output mirror and an output mirror cooling device. The discharge tube is filled with carbon dioxide gas and other auxiliary gases. When a high voltage is applied to the electrodes, a glow discharge is generated in the discharge tube. After being reflected by the reflecting mirror and the output mirror, a laser beam is formed and emitted from the output mirror to obtain the final laser beam. Based on the working principle of carbon dioxide lasers, when a current of tens or hundreds of milliamperes is input, the gas molecules in the carbon dioxide laser are excited by electron collisions during electrode discharge. These excited gas molecules then collide with carbon dioxide molecules, causing the carbon dioxide molecules to transition from lower energy levels to higher energy levels, resulting in population inversion and emitting laser light. Because the core tube of the carbon dioxide laser, i.e., the discharge tube, bends downwards under gravity, it affects the reflection of the laser light within the tube. Furthermore, since the gas storage tube, water cooling tube, and discharge tube of the laser are all made of glass, they have poor plasticity and impact resistance. Therefore, a support frame is needed to provide radial support while also possessing a certain degree of elasticity in the radial direction to ensure the laser's stability. When subjected to radial impact, the support frame can provide a certain degree of elastic deformation to prevent damage to the various slender tubes inside the laser due to radial impact. Secondly, during the handling and transportation of the laser, it is often subjected to impact forces along the length direction, so the support frame also needs to provide support force along the length of the laser. However, when the laser is working, the temperature of the discharge tube and water cooling tube gradually increases, causing the length of the discharge tube and water cooling tube to also have a certain amount of elongation. Therefore, while providing support force along the length of the laser, the support frame also needs to have a certain degree of elasticity along the length of the laser to play a buffering role and prevent damage to the various slender tubes inside the laser due to impacts along the length of the laser.
[0003] In existing technologies, the discharge tube support cylinder for carbon dioxide lasers uses a support ring installed between the water-cooling jacket and the discharge tube to support the tube. This support ring is an integral piece consisting of a circular ring and multiple support claws, mounted on the discharge tube. The support claws include inner claws and outer claws. The inner claws contact the outer edge of the discharge tube, and the outer claws contact the inner edge of the cooling jacket, thus supporting the discharge tube. However, the circular area of the support ring is relatively large, which increases water resistance, reduces water flow velocity, and affects the cooling effect. Furthermore, it requires additional support equipment, increasing production costs. The external support claws are also prone to detaching from the support ring, thereby damaging the laser.
[0004] Therefore, in view of the existing problems, how to provide a carbon dioxide laser with a discharge tube support structure that can ensure that the discharge tube is not damaged by impacts along the length or radial direction of the laser during normal use and transportation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] Therefore, this utility model provides a carbon dioxide laser with a discharge tube support structure, which can ensure that the discharge tube is not damaged by impacts along the length or radial direction of the laser during normal use and transportation of the carbon dioxide laser.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A carbon dioxide laser with a discharge tube support structure includes: a gas storage tube, a water cooling tube, and a discharge tube coaxially sleeved from the outside to the inside, with a sealed cavity formed between the water cooling tube and the discharge tube; an inlet pipe and an outlet pipe are fixed to the side wall of the water cooling tube, and both the inlet pipe and the outlet pipe penetrate and connect to the side wall of the gas storage tube; and further includes:
[0008] A spiral support plate is located inside the sealed cavity and coaxially sleeved on the outer wall of the discharge tube. The two ends of the spiral support plate are staggered, with one end fixed on the inner wall of the water-cooling pipe and the other end fixed on the outer wall of the discharge tube. The spiral support plate is elastic along the axial direction of the discharge tube.
[0009] An elastic support blade is provided, with one end fixed to the side wall of the spiral support plate and the other end abutting against the inner side wall of the water-cooling pipe.
[0010] Through the above technical solution, this utility model provides a carbon dioxide laser with a discharge tube support structure. By coaxially sleeved on the outer wall of the discharge tube with staggered ends, one end is fixed to the inner wall of the water-cooling tube and the other end is fixed to the outer wall of the discharge tube, the spiral support plate can maintain a certain elastic adaptation to the elongation generated during the normal operation of the carbon dioxide laser, avoiding impact on the slender tube in the length direction. At the same time, the use of an integrated spiral support plate and elastic support blades prevents damage to the laser caused by unstable connection or even detachment between the elastic support blades and the spiral support plate. It can also avoid radial impact during the handling and transportation of the laser and provide radial support force to the discharge tube. In addition, the overall support structure is simple.
[0011] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, the spiral support plate has through holes. This ensures that water in the water-cooling pipe can pass through smoothly, reducing resistance during operation.
[0012] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, there is a gap between the inner side of the spiral support plate and the outer wall of the discharge tube, and a gap between the outer side of the spiral support plate and the inner wall of the water-cooling tube. The elastic support blade is located within the gap between the outer side of the spiral support plate and the inner wall of the water-cooling tube. This ensures that water in the water-cooling tube can pass smoothly, reducing resistance during operation.
[0013] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, a first protrusion is provided on the outer side of one end of the spiral support plate, and the first protrusion is fixedly connected to the inner wall of the water-cooling tube. A second protrusion is provided on the inner side of the other end, and the second protrusion is fixedly connected to the outer wall of the discharge tube. This ensures that a gap always exists between the spiral support plate and the water-cooling tube and the discharge tube.
[0014] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, the number of elastic support blades is multiple, and they are fixed to the outer wall of the spiral support plate at uniform intervals. This ensures that the elastic support blades can act evenly on the circumference of the tube.
[0015] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, the end of the elastic support blade that abuts against the water-cooling tube is semi-circular. This ensures that the elastic support blade can better cooperate with the water-cooling tube.
[0016] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, there are multiple spiral support plates, which are evenly spaced along the length of the discharge tube. This ensures that they act uniformly along the entire length of the tube, meeting the support requirements.
[0017] Preferably, in the aforementioned carbon dioxide laser with a discharge tube support structure, the spiral support plate is made of the same material as the water-cooling tube and the discharge tube. This ensures that the spiral support plate has the same coefficient of thermal expansion as the water-cooling tube and the discharge tube, allowing for consistent deformation and preventing strain on the tubes that could affect the laser's output accuracy.
[0018] Preferably, in the above-mentioned carbon dioxide laser with a discharge tube support structure, an anode resonant cavity and a cathode resonant cavity are respectively provided at both ends of the discharge tube, and an anode electrode and a cathode electrode are respectively provided in the anode resonant cavity and the cathode resonant cavity.
[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a carbon dioxide laser with a discharge tube support structure, which has the following beneficial effects:
[0020] This invention involves coaxially mounting a spiral support plate onto the outer wall of the discharge tube, with the two ends staggered. One end is fixed to the inner wall of the water-cooling tube, and the other end is fixed to the outer wall of the discharge tube. This allows the spiral support plate to maintain a certain elastic adaptability to the elongation generated during the normal operation of the carbon dioxide laser, avoiding impact on the slender tube in the length direction. At the same time, the integrated spiral support plate and elastic support blades prevent damage to the laser caused by unstable connection or even detachment between the elastic support blades and the spiral support plate. It also avoids radial impact during laser handling and transportation, and provides radial support force to the discharge tube. In addition, the overall support structure is simple.
