Butting positioning tool for arc striking and quenching plates and positioning butting method thereof

Abstract

The invention provides a butting positioning tool for arc striking and quenching plates and a positioning butting method thereof. The tool is provided with a translation sliding table for aligning thetool and a pipe end; the translation sliding table drives a lifting platform to lift through a vertical lifting cylinder, the lifting platform is provided with a loading platform in parallel throughflexible self-adaptive assemblies, the loading platform is provided with profiling roller assemblies for aligning the arc plates and the pipe end, the loading platform is provided with a pair of positioning and clamping mechanisms, and the lifting platform is provided with a pair of horizontal pushing mechanisms and a pressing mechanism; and automatic lifting, pushing, approaching, clamping, centering, fixing, abutting and downward pressing and aligning operations of the arc places with respect to the pipe end are realized through the mechanisms. The manpower is replaced, and the automatic plate aligning and positioning operation before welding of the arc striking and quenching plates is realized in a high efficiency, labor-saving and accurate mode.

Description

technical field [0001] The invention belongs to the technical field of arc welding auxiliary tooling for operation and transportation, and in particular relates to a docking and positioning tool for ignition and extinguishing arc plates and a positioning and docking method thereof. Background technique [0002] In the submerged arc welding production process of straight seam or spiral welded seam steel pipe, the arc ignition and arc extinguishing stages of submerged arc welding are prone to slag inclusions and pore welding quality defects; in order to improve the welding quality, it is necessary to start and At the end, weld an arc-extinguishing plate for extension to ensure the consistency of the weld seam quality of the steel pipe; and after the welding is completed, cut off the arc plate to ensure the welding quality of the steel pipe. At present, the preparatory work before welding the extinguishing arc plate and the pipe end requires manual lifting of the plate, manual ...

AI Technical Summary

Problems solved by technology

However, this device can only replace the manual operation of lifting the arc plate and closing the arc plate to the pipe end; the most critical coaxial alignment between the arc plate and the pipe end and the close operation of the arc plate and the pipe end still need to be completed manually; therefore The use of this device has not fundamentally solved the technical problems of automatic alignment between the arc extinguishing plate and the pipe end, as well as automatic tightening and clamping, and the problem of inconsistent welding quality stability still exists

Publication No. CN110125520A discloses a clamping device for extinguishing arc plates; this device only solves the technical problem of clamping arc plates with different thicknesses, but does not solve the alignment of arc plates and pipe ends and the alignment of arc plates. The technical problem of closeness to the pipe end; not only that, the clamping of the arc plate of the device is realized by bolts; the efficiency of the clamping operation is low; the convenience of the device is not ideal
