Problems solved by technology

[0005] In order to overcome the shortcoming that the steel plate is prone to displacement during welding, resulting in virtual welding, it is necessary to manually put the electrode into the joint of the steel plate at a uniform speed for welding, and the operation is relatively complicated. Technical problem: provide an automatic clamping steel plate, The steel plate is not easy to loosen during welding, avoiding false welding, and can drive the electrode to move down at a constant speed. The welding quality is good, and the automatic steel plate welding robot arm is easy to operate.

Abstract

The invention relates to a mechanical arm, in particular to an automatic steel plate welding mechanical arm. The invention aims to provide the automatic steel plate welding mechanical arm which can clamp a steel plate automatically, the steel plate is unlikely to loosen if being welded to avoid false welding, a welding rod can be driven at a uniform speed to move downward, and the automatic steelplate welding mechanical arm is relatively good in welding quality and simple to operate. The automatic steel plate welding mechanical arm comprises a supporting leg, a placing plate and the like. Thesupporting leg is mounted on the placing plate. A hollow round pipe can be driven by an electric push rod to move left and right. By matching an annular plate with a contact plate, the welding rod can be compacted and loosened by means of a first spring. By matching a chute board with a rolling shaft, the welding rod moves vertically while moving transversely to further weld the steel plate. A second clamping plate is pulled by an n-shaped rod, so that the steel plate needed to be welded can be fixed conveniently. When the steel plate is welded, welding inaccuracy caused by displacement of the steel plate is avoided.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a steel plate automatic welding mechanical arm. Background technique [0002] The steel plate is a flat steel that is poured with molten steel and pressed after cooling. It can be rolled directly or cut from a wide steel strip. The steel plate is divided into thicknesses, thin steel plate <4mm (thinnest 0.2mm), medium-thick steel plate 4-60 mm, extra-thick steel plate 60-115 mm, steel plate is divided into hot rolling and cold rolling according to rolling. [0003] When the steel plates are being welded, the operator needs to place the two steel plates on the same level, and then the operator uses the welding torch to clamp the welding rod to weld them. In this way, the steel plates are prone to displacement during welding, resulting in virtual welding. At the same time, manual uniform speed is required Putting the welding rod into the joint of the steel plate for welding, the operation is...
