Abstract

The invention discloses a small-pipe-diameter pipeline cutting and bevelling machine, and belongs to the technical field of pipeline mounting engineering. A power handle 33 is in butt joint with a small gear shaft 21 through a connecting block 3301, and power is transmitted to a moving ring of a main cutting motion mechanism; a clamping mechanism is mounted on a static ring I 15 and a static ringII 14 in the main cutting motion mechanism to clamp workpieces; and a radial feed mechanism is fixed to the moving ring in the main cutting motion mechanism and does radial feed motion of a tool through a stirring rod 7. According to the small-pipe-diameter pipeline cutting and bevelling machine, motion and force are transmitted to a mechanism body through a pair of bevel gears, the energy transmission direction and the operation direction are changed, and operation of operators is facilitated; a throttle valve, a filter, a gate valve, a pneumatic motor, the bevel gears and the other mechanisms are integrated in a power handle, and good integration and portability are achieved; and through replacement of clamping blocks of different lengths, the aims of clamping pipelines of different pipediameters and achieving cutting and bevelling are achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline installation engineering, in particular to a small-diameter pipeline cutting and beveling machine. Background technique [0002] Pipeline repair and welding work is frequently encountered on engineering projects, many of which are buried underground or completely exposed. Pipelines that have been underground for a long time will be retested by acid and other substances, and pipelines that have been exposed for a long time will be damaged or even broken due to natural and human factors, so regular inspections and corrections are required. [0003] The pipe cutting and beveling machine refers to the pipe cutting or beveling operation when the pipe needs to be repaired and installed. It solves the shortcomings of flame cutting, grinder grinding and other operating processes such as irregular angles, rough slopes, and high working noise. It has the advantages of easy operation, standard angle and sm...
