Automatic butt joint and grinding-in tooling equipment of large barrel

Abstract

The invention discloses automatic butt joint and grinding-in tooling equipment of a large barrel, which is mainly composed of a barrel rolling rack and a barrel moving rack, wherein the axis of two rows of transmission shafts on the barrel rolling rack and the axis of two rows of transmission shafts on the barrel moving rack are on the same horizontal plane, and the axis of two rows of transmission shafts of two types of racks at the same side is collinear so as to ensure that the butt joint barrels are on the same axis; the barrel on the moving rack carries out linear displacement under the transmission action of a moving rack lead screw so as to realize automatic butt joint; under the axial pressure maintained by spring extension, circumference grinding is carried out to enhance the butt joint precision of two barrels; the transmission of the moving rack lead screw drives the butt joint barrel to carry out the linear displacement; and the butt join barrel on the rolling rack carries out circumference rolling to form an opposite spiral butt join-grinding movement with the linear displacement barrel on the moving rack. The tooling equipment of the invention improves equipment service life, reduces energy consumption, improves precision, has simple structure, strong reliability, high butt join precision and speed, time and labor saving, safety and high efficiency and lowers equipment investment.

Description

technical field [0001] The invention relates to a tooling device, in particular to an automatic butt running-in tooling device suitable for a large cylinder. Background technique [0002] At present, the method used for the docking of large cylinders is divided into three steps. In the first step, use a bridge crane to suspend one cylinder, gradually approach the other cylinder under manual adjustment, put down the cylinder in a suitable position according to the operator's observation, or use a hoist to discharge the two cylinders on the support frame. The cylinders are pulled together. The second step is to evenly spot weld four positions on the circumference of the butt gap. In the third step, the positioned cylinder is hoisted to the rolling frame, and the inner and outer welds are filled by methods such as submerged arc automatic welding to realize the riveting of the cylinder. The problems with this method of operation are: when the two cylinders are only connected ...

AI Technical Summary

Problems solved by technology

The problem with this method of operation is: when the two cylinders are only docked axially, there is no circumferential running-in, and the docking accuracy cannot be guaranteed; it is necessary to manually adjust the orientation of the cylinders under the bridge crane, the docking speed is slow, and the risk factor is high; Using a hoist to drag the cylinder on the support frame, the friction is large, which reduces the accuracy and life of the equipment and increases energy consumption; the process is scattered, the cylinder is hoisted frequently, the number of workers is large, the labor intensity is high, and the work efficiency is not high.
