Tubular part welding rapid butt-joint positioning device

Abstract

The invention discloses a tubular part welding rapid butt-joint positioning device. A fixed clamping assembly and a movable clamping assembly are coaxially arranged in a spaced mode on the inner sides of a pair of supporting frames arranged in a spaced mode. The movable clamping assembly can be driven by a first pushing assembly to translate in the axial direction so as to change the distance between the fixed clamping assembly and the movable clamping assembly. Through grooves are formed in the tops of the two supporting frames in the axial directions of the clamping assemblies correspondingly. Movable supporting blocks are arranged at the bottoms of the through grooves. A plurality of universal balls are movably installed on the movable supporting blocks at intervals and can rotate on the movable supporting blocks. The tops of the universal balls are exposed out of the upper portions of the movable supporting blocks to form supporting faces. The movable supporting blocks can be pushed by a third pushing assembly to move in the depth direction of groove cavities of the through grooves. The device further comprises a plurality of independently separated buffer gaskets with different thicknesses. The device is simple and compact in structure, positioning is accurate, operation is simple and the safety performance is high.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an alignment technology for welding and butt jointing of tubular parts. Background technique [0002] Pipes of different materials, especially when metal pipes or PP pipes need to be butt-jointed, are currently commonly used in the industry for pipe hot-melt welding, pipe thread connection, pipe flange connection and other connection methods. In piping engineering, the welding of pipe joints occupies a large workload. The conventional manual welding method is time-consuming and laborious, and the welding accuracy and the coaxiality of the pipes cannot be guaranteed, which is prone to middle misalignment and uneven weld seams. and other problems; the existing welding construction device needs a variety of equipment to be used in conjunction, and the equipment is easily restricted by the limited construction space when erecting the equipment, which is not conducive to on-site o...
