Supporting tool for cylinder welding

Abstract

The invention discloses a supporting tool for cylinder welding. The supporting tool is characterized by comprising a bottom supporting part and a side supporting part, wherein the bottom supporting part comprises a bottom frame; at least one row of supporting assemblies in bilateral symmetry are arranged on the bottom frame; each supporting assembly consists of a roller wheel bracket and supporting roller wheels which are arranged on the roller wheel bracket through a wheel axle; the bottom supporting part also comprises an adjusting mechanism which is connected with each roller wheel bracket and the bottom frame; the side supporting part comprises a base, a vertical column and a supporting rod; the lower end of the vertical column is fixedly connected with the base; one end of the supporting rod is detachably, vertically and fixedly connected with the vertical column; a plurality of bearings are sleeved on position on the supporting rod and far away from one end, connected with the vertical column, of the supporting rod; the supporting rod is suspended over the left and right supporting assemblies. The supporting tool is used for performing stable three-point supporting positioning on a cylinder, the supporting stability is improved, the butting coaxiality of two or more cylinders is ensured, the operation is facilitated, the operation time is saved, the welding efficiency is improved, and usage requirements of the cylinders with different diameters are met.

Description

technical field [0001] The invention relates to a tooling for workpiece welding, in particular to a supporting tooling suitable for welding longitudinal welds or transverse welds of large cylindrical workpieces. Background technique [0002] In the prior art, the welding of large cylindrical workpieces includes the welding of the longitudinal seam behind the drum of a single cylinder and the butt joint of two or more cylinders along the transverse direction (also called the welding of the transverse seam). At present, when the longitudinal seam or transverse seam welding is carried out on the cylinder body, it is completed by placing the cylinder body on the support tooling located at the lower end. The problems existing in the use of the existing support tooling are: [0003] 1. The support for the cylinder is two-point support. Due to the large radial size of the cylinder, the stability of the support for the cylinder is poor, and the problem of cylinder dumping is prone t...

AI Technical Summary

Problems solved by technology

[0003] 1. The support for the cylinder is two-point support. Due to the large radial size of the cylinder, the stability of the support for the cylinder is poor, and the problem of cylinder dumping is prone to occur;

[0004] 2. When two cylinders or multiple cylinders are docked, it is completed by placing the two cylinders or multiple cylinders on two or more independent supporting tools, so the coaxiality of the cylinders cannot be guaranteed;

[0005] 3. The existing support tooling cannot be flexibly adjusted according to the diameter of the cylinder, resulting in poor applicability to cylinders with different diameters
