Description

Torch clamping mechanism for deep hole welding

technical field

The utility model belongs to the technical field of welding equipment, in particular to a welding torch clamping mechanism which can be used for deep hole welding.

Background technique

The welding industry is responsible for the most widely used material joining process, is the lifeblood of the manufacturing industry and the key to future competitiveness. When processing or repairing large deep-hole parts such as cylinder blocks, the original casting loose defects or damages still exist after the cracks are polished off by mechanical methods. Applying welding and joining technology to repair similar non-welded structural parts and components is particularly important in the repair and life extension of manufactured products.

The current deep hole welding processing or repair method: the deep hole parts make slow circular motion under the clamping of the three-axis chuck, and the welding torch performs axial reciprocating welding under the clamping of the tool during one rotation cycle of the workpiece. The welding torch is fed axially and continues the reciprocating welding work, and completes the welding and repairing work of the entire deep hole in turn. Since the workpiece has strict requirements on the distance between the welding torch and the weldment during welding, the current welding clamping mechanism is mostly a cantilever bracket, which has the following disadvantages when used as a deep hole welding tool:

1. The welding length is limited due to the sagging of the cantilever rod, which requires two or even multiple repair welding work;

2. The resistance of the screw motor with axial reciprocating motion is large;

3. It is difficult to clean up the welding slag and the heat dissipation effect is poor.

It can be seen that in view of the above defects in the current deep hole welding processing and repair work, it is imminent to develop a convenient and safe welding torch clamping mechanism that integrates deep hole welding, heat dissipation, and slag removal.
