Device for positioning flange hole of steel tube intersection line cutting machine

Abstract

The invention relates to a device for positioning a flange hole of a steel tube intersection line cutting machine, which belongs to the technical field of steel tube intersection line cutting machine apparatuses and is used for automatically positioning a machined steel tube flange. The technical scheme is as follows: the device provided by the invention is composed of a shift device, an oscillating bar, a mounting plate, an oscillating cylinder and a laser ranging sensor, wherein the shift device is mounted on a lifting shaft sliding plate of the steel tube intersection line cutting machine through a bracket; one end of the oscillating bar is connected with the shift device via a rotating shaft, and the other end of the oscillating bar is connected with the mounting plate; the oscillating cylinder is mounted on the mounting plate; the front end of an oscillating shaft of the oscillating cylinder is connected with the laser ranging sensor; and a signal output end of the laser ranging sensor is connected with a control device of the steel tube intersection line cutting machine. The angle of the device provided by the invention can be changed under the rotation of the oscillating cylinder, thereby automatically detecting the position of the machined steel tube flange and finishing the angle positioning of the flange hole. Thus, the device provided by the invention has the characteristics of high measurement accuracy, high efficiency, quick and convenient operation process and the like, ensures the machining accuracy and meets the production requirements.

Description

technical field [0001] The invention relates to a steel pipe intersecting line cutting machine for processing flanged steel pipes, belonging to the technical field of steel pipe intersecting line cutting machine equipment. Background technique [0002] The steel pipe intersecting line cutting machine has been widely used. It is a device that automatically cuts the intersecting line holes, intersecting line ends and elbows at the junction of steel pipes and non-ferrous metal pipes. This machine is widely used in the cutting and processing of pipeline structural parts in construction, chemical industry, shipbuilding, mechanical engineering, metallurgy, electric power and other industries. However, when implementing intersecting line cutting for steel pipes with welded flanges, it is necessary to consider the angular relative position of the intersecting line and the flange mounting hole, and the angle positioning of the flange hole usually needs to be manually adjusted before ...

AI Technical Summary

Problems solved by technology

However, when performing intersecting line cutting on steel pipes that have been welded with flanges, it is necessary to consider the angular relative position of the intersecting line and the flange mounting hole, and the angle positioning of the flange hole usually needs to be adjusted manually before the intersecting line can be cut. Cutting and adjustment accuracy are not easy to grasp, and the adjustment speed is slow, which cannot meet the needs of production
