The utility model discloses a
carbon dioxide laser tube with a water-cooled tube support column, which comprises a gas
storage tube, a water-cooled tube and a
discharge tube which are sequentially sleeved from outside to inside, a positive
electrode and a negative
electrode are respectively arranged at two ends of the
discharge tube, a spiral tube is arranged outside the negative
electrode in a surrounding manner, and the spiral tube is connected with the water-cooled tube support column. The two ends of the spiral
pipe are communicated with the
water cooling pipe and the water inlet
pipe respectively, and the two ends of the supporting column are connected with the gas storage pipe and the
water cooling pipe in a burning and
casting mode respectively. According to the utility model, on the basis of providing deformation and performing heat insulation through the spiral tube, the support column
rigid structure is additionally arranged, so that a more stable support effect can be provided when the
laser tube is processed, and the consistency of the central axis of the
discharge tube and the
water cooling tube and the central axis of the
laser tube is improved. In the movement process of the
laser tube, the stability of the
laser tube is improved, the deviation phenomenon of the water cooling tube and the discharge tube caused by the shaking of the spiral tube is reduced, and the reduction of the output power and the
instability of output light spots during the movement of the
laser tube are reduced.
