Abstract

The invention provides a clamping device used for assembling of an aluminum alloy hull. The clamping device comprises a movable supporting frame and a brace foot. The movable supporting frame comprises a positioning support, a first supporting piece and at least two second supporting pieces. The lower end of the first supporting piece is vertically mounted on the positioning support. The brace foot is arranged at the upper end of the first supporting piece. All the second supporting pieces are horizontally connected to the positioning support, and clamps are mounted on the second supporting pieces correspondingly. The clamping device is high in strength, deformation can be controlled easily, the tightness can be adjusted flexibly according to conditions, the whole device is simple in structure, and manufacturing is convenient. The whole process of a manufacturing method of the clamping device is extremely simple and convenient to implement, the strength of the clamping device manufactured through the method is high, deformation can be controlled by flexibly adjusting the tightness, and the process is reliable.

Description

technical field [0001] The invention relates to a cam used for assembling an aluminum alloy hull and a manufacturing method thereof. Background technique [0002] Chamfer is an essential tooling for the welding of the hull structure on the tooling frame. In the past, steel ships generally used simple clamps made of twisted steel flat bars during the construction process. Small, requires a large quantity and is not easy to reuse, and the consumables are serious. However, considering the quality of welding on the tooling tire frame, so far, this kind of Kama has been used on steel products. However, for the aluminum alloy hull structure, the thickness of the aluminum alloy plate is relatively thin, and it is easy to deform. The construction of the aluminum alloy hull sections adopts a template type tire frame, and is elastically fixed with a simple clamp to prevent deformation. Purpose. However, this simple bolt jammer has the following disadvantages in the process of weldi...

AI Technical Summary

Problems solved by technology

[0003] 1. The thermal expansion coefficient of aluminum alloy is large, and the material itself is more prone to deformation than steel material. When the aluminum alloy workpiece is welded on the tire, during the heating and cooling process, due to the different heat conduction conditions of some parts, the temperature field is not uniform, resulting in some The elastic modulus and thermal expansion coefficient of the workpiece are different, and the welding residual stress will be generated on the surface of the workpiece, and the deformation caused by heating is large and difficult to control.

[0004] 2. The simple clamp adopts multiple spot welding, and there are too many consumables. Due to the different deformation degrees of the aluminum alloy plate under the heating condition, there is a complex deformation trend of convex and concave, which leads to the simple clamp for fixing the tire. It is necessary to continuously adjust the tightness, the labor cost is too high, time-consuming and labor-intensive, the operation is inconvenient, the construction is difficult and the precision is low
