Auxiliary ejecting-supporting device

Abstract

The invention discloses an auxiliary ejecting-supporting device which comprises an annular base plate.Clamping supports and ejecting-supporting supports are distributed on the annular base plate, a positioning ring is arranged at the upper end of each clamping support and is sleeved with an adjusting ring, the clamping supports are provided with adjusting ejection rods pointing to the outer sides of the adjusting rings, the outer sides of the adjusting rings are oblique planes, telescopic air cylinders are built in the clamping supports and the ejecting-supporting supports, telescopic ejecting-supporting rods are arranged on the ejecting-supporting supports, and swingable horizontal pull rods are arranged at the ends of the telescopic ejecting-supporting rods.The auxiliary ejecting-supporting device is simple in structure and convenient to use through reasonable structural improvement, especially through matching between the adjusting rings with the oblique planes and the adjusting ejection rods on the outer sides, according to the submerged-arc welding need of a large-specification flange part, drives the adjusting ejection rods to telescope through the telescopic air cylinders, accordingly supports the flange part to be welded radially and tightly, conveniently loosens the adjusting ejection rods through matching between the telescopic ejecting-supporting rods and the horizontal pull rods, and facilitates fine adjustment of a clamping position.

Description

technical field [0001] The invention relates to the technical field of submerged arc welding, in particular to an auxiliary supporting device for welding of large-scale generating set base casing welding equipment. Background technique [0002] The generator set base casing needs to be turned over for welding during the production process, but due to its large size and weight, there is a problem of difficulty in turning over. In the prior art, the patent No. 201320628055.8 "An Automatic Submerged Arc Welding Flange Tooling" mentioned that the base is connected to the workbench through uprights around the base, and a rotating device is installed in the base, and the rotating device passes through a plane bearing and a three-jaw clamp. The three-jaw chuck is used to support the steel pipe to be welded and can be automatically centered. There are several height-adjusting bolts on the workbench for positioning the flatness of the flange, and several calibration cylinders are eve...

[0002] The generator base shell needs to be turned over for welding during the production process, but due to its large size and weight, there is a problem of difficulty in turning over

In the prior art, the patent No. 201320628055.8 "An Automatic Submerged Arc Welding Flange Tooling" mentioned that the base is connected to the workbench through uprights around the base, and a rotating device is installed in the base, and the rotating device passes through a plane bearing and a three-jaw clamp. The three-jaw chuck is used to support the steel pipe to be welded and can be automatically centered. There are several height-adjusting bolts on the workbench for positioning the flatness of the flange, and several calibration cylinders are evenly installed around the workbench. , one end of the calibration cylinder is equipped with a push rod design, but the strength of this design is still not suitable for the welding work of the base shell of the generator set
