Problems solved by technology
[0002] In the production of absorption-diffusion refrigeration equipment, due to its low refrigeration efficiency, it is generally adopted to tap the inner wall of the evaporation tube of the refrigeration equipment to expand the contact area between the inner wall of the evaporation tube and the refrigerant, and prolong the refrigerant in the evaporation tube. flow path, thereby improving refrigeration efficiency, since the caliber of the evaporating tube is fixed, if it is tapped with an ordinary tapping machine, it is necessary to use a clamping mechanism adjusted by the thread every time the evaporating tube is fixed or taken out. Fixing or taking out the evaporating tube, the production efficiency is low, and improper control of the clamping degree of the evaporating tube will cause the evaporating tube to be deformed or even scrapped

The invention discloses a tube clamping device for a tapping machine. The tube clamping device comprises a base, a fixed clamping seat, a movable clamping seat and two locking shafts which horizontally penetrate through the fixed clamping seat and the movable clamping seat, wherein the fixed clamping seat is fixedly arranged on the base; a clamping slot is reserved between the fixed clamping seat and the movable clamping seat; two ends of each of the locking shafts penetrate through the fixed clamping seat and the movable clamping seat respectively; one end of each of the locking shafts, which penetrates through the movable clamping seat, is provided with a stopping piece; a cam is hinged between ends of the two locking shafts, which penetrate through the fixed clamping seat; and the cam is connected with a hand shank. The cam is used for controlling opening and closing of the fixed clamping seat and the movable clamping seat, so that an evaporation tube can be clamped or taken out conveniently, and the work efficiency is improved greatly; furthermore, the clamping force of the clamping slot reserved between the movable clamping seat and the fixed clamping seat can be set properly by adjusting a distance between the movable clamping seat and the fixed clamping seat; and the phenomenon of deformation or damage caused by over-clamping to the evaporation tube is well avoided.
