Armored car body welding tool

Abstract

The invention relates to the technical field of tool tools, in particular to an armored car body welding tool. The welding tool which is high in automation degree and good in welding quality and is used in a friction stir welding method is provided. According to the solution, the tool is provided with a base, a left inner supporting base for supporting a left side plate and a right inner supporting base for supporting a right side plate are arranged on the base, a left turning plate and a right turning plate which can turn laterally and press the side plates on the supporting bases are arranged on the outer side of the left inner supporting base and the outer side of the right inner supporting base correspondingly, turning type pressing oil cylinders which press a bottom plate on the top face are arranged on the left turning plate and the right turning plate, a bracket for supporting the front top plate is arranged on the base, the bracket is provided with a first pressing portion and a second pressing portion which press the front top plate, one end of the second pressing part is hinged to the first pressing part, the other end of the second pressing part is detachably fixed to a stand column arranged on the base, a pushing and pressing device for positioning the side plates is also arranged on the base at the weld joints of the front top plate, and the side plates and tail clamping devices for clamping a tail plate are arranged on the rear end surfaces of the left turning plate and the right turning plate.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a welding tooling for an armored vehicle body. Background technique [0002] The steel plate used in the explosion-proof armored vehicle body is relatively thick, and the steel plates between different positions are welded to form the car body. The welding generally adopts the form of opening a bevel at the welding place and then performing electric welding. The electric welding can be done manually or by a welding robot. This welding The disadvantage is that due to the thick steel plate, there will be insufficient connection strength at the welding place. Some welding positions cannot be completed by welding robots and need to be completed manually. In addition, the process stability of the electric welding process is slightly poor, and a flaw detection process is often required. Like this, the manufacturing process of whole car body is complicated and lengthy, and seek...

[0002] The steel plate used in the explosion-proof armored vehicle body is relatively thick, and the steel plates between different positions are welded to form the car body. The welding generally adopts the form of opening a bevel at the welding place and then performing electric welding. The electric welding can be done manually or by a welding robot. This welding The disadvantage is that due to the thick steel plate, there will be insufficient connection strength at the welding place. Some welding positions cannot be completed by welding robots and need to be completed manually. In addition, the process stability of the electric welding process is slightly poor, and a flaw detection process is often required. In this way, the manufacturing process of the entire car body is complicated and lengthy, and it is a task to seek a car body processing method with a high degree of automation and good welding quality.
