Abstract

The invention relates to an elbow pipe beveling fixture comprising a positioning plate I, a positioning plate II, a supporting plate, a baseplate and a clamping cover. The positioning plate I, the positioning plate II and the supporting plate are perpendicularly fixed on the baseplate; the inclined angle between the positioning plate I and the positioning plate II ranges from 40 to 50 DEG, the inclined angle between the supporting plate and the positioning plate I ranges from 40 to 50 DEG, and the supporting plate and the positioning plate II ranges from 80 to 100 DEG. The ends, far from the baseplate, of the positioning plate I, the positioning plate II and the supporting plate are respectively provided with semi-circular grooves, and the determined curvature radius of the centers of the semi-circular grooves of the positioning plate I, positioning plate II and supporting plate are the same as those of the outer circle of an elbow pipe. One ends of the semi-circular grooves of the positioning plate I and positioning plate II are provided with the clamping cover used for clamping the elbow. The elbow pipe beveling fixture has the advantages that the elbow pipe can be positioned and clamped rapidly when a welded elbow pipe beveling machine bevels.

Description

technical field [0001] The invention relates to a clamp, in particular to a beveling clamp for an elbow pipe fitting. Background technique [0002] Chemical, petrochemical and other industries need to lay a large number of pipelines. Each section of pipeline needs to be connected by welding when laying. In the laying of pipelines, the use of various elbows is essential. Both ends of each welded elbow need to be grooved at 45o or 60o. Unqualified groove processing will affect the welding quality of pipe fittings and the quality indicators such as straightness and verticality of the entire pipeline. The beveling is generally processed on a special machine tool for bevelling of pipe fittings. Due to the shape of the elbow itself, its positioning and clamping during groove processing are significantly different from those of ordinary straight pipe fittings. In mass production, how to ensure the quality of the welding groove of each elbow and improve the production efficienc...
