Flange automatic alignment conveying device

Abstract

The invention relates to an automatic alignment conveying device for flanges. The automatic alignment conveying device mainly solves the problem that corresponding bolt holes in the flanges at the twoends of a steel pipe cannot keep concentric. The automatic alignment conveying device is characterized in that a hollow rotary shaft (4) is arranged on a sliding base (2), at least three clamping jaws (6) are hinged to a clamp base (5), a clamping air cylinder (7) is fixed to the other end of the hollow rotary shaft (4), a retractable alignment elastic pin (8) is arrranged on the clamp base (5),an alignment gear (9) is fixed to the outer side of the hollow rotary shaft (4) and meshes with an alignment rack (11) connected to a piston rod of the alignment air cylinder (10), and the rotation angle of the alignment gear (9) is not smaller than the included angle of the two adjacent bolt holes in each flange. The automatic alignment conveying device has the advantage that the bolt holes of the flanges at the two ends can keep at the same position before the flanges are welded to the metal pipe so as to ensure that the corresponding bolt holes in the flanges at the two ends of the steel pipe can be located on the same axis line.

Description

technical field [0001] The invention relates to a pipe fitting processing tool, in particular to a flange automatic alignment conveying device. Background technique [0002] Steel pipes are often used to convey media such as fluids and powders. Flanges are often used to connect steel pipes. Usually, the flanges are welded to both ends of the steel pipes. When in use, the flanges on the two steel pipes are connected by bolts. Use the neck structure first. During processing, the end of the steel pipe is inserted into the inner hole of the necked flange, and then welded at the intersection of the inner hole of the flange and the end of the steel pipe and at the junction of the neck of the flange and the outer wall of the steel pipe. At present, the welding between the neck flange and the steel pipe is manually welded, and the corresponding bolt holes on the flanges at both ends of the steel pipe cannot keep the same axis, which brings inconvenience to the connection of the ste...
