Description

Automatic welding workstation for door plate of switch cabinet Technical Field The invention relates to the technical field of welding, in particular to an automatic welding workstation for a door plate of a switch cabinet. Background The switch cabinet door plate is an openable metal panel arranged on the front side of high-low voltage switch equipment (such as a power distribution cabinet, a control cabinet and the like), is mainly used for protecting internal electric elements, realizing the integration of an operation interface and guaranteeing the operation safety, and is widely applied to the fields of power systems, industrial automation and the like. In the manufacturing process of the door plate, a plurality of reinforcing ribs are welded on the inner side of the door plate, so that the bending strength and the shock resistance of the door plate are improved, and the door plate is prevented from being deformed when being used for a long time or subjected to external force. The quality of the welding seam between the reinforcing rib and the door plate directly influences the overall structural strength and the service life of the door plate. However, the following problems still exist in the process of welding the reinforcing ribs in the shape of a Chinese character 'ji' on the inner side of the door plate at present: The door plant has the mouth style of calligraphy banding structure that the turn-ups formed all around, the length or width size of several font strengthening ribs is basically equivalent with banding inner chamber size, even there is interference fit under the partial circumstances, under this size relation, the strengthening rib can't directly put into the banding with the horizontal gesture and enclose the regional inside that closes, must incline certain angle with the strengthening rib by the manual work first, make its one end get into the banding inboard, then utilize metal material's elastic deformation, break off with the fingers and thumb the straightness and pass along the door plant plane direction with the strengthening rib, just can send it to preset welding position, this mode of operation relies on manual experience, inefficiency. When two strengthening ribs need to be placed, because the space of the edge sealing inner cavity is limited, the strengthening ribs placed firstly occupy the inner space, and the strengthening ribs placed later are easy to interfere with the strengthening ribs in place when entering obliquely, so that assembly cannot be completed smoothly, and the operation difficulty and the time cost are further increased. In addition, the U-shaped reinforcing ribs are opening section members formed by sheet cold bending, stress concentration areas exist at bent corners between the side walls and the bottom surface of the opening section members, and local concentrated force applied during manual straightening is extremely easy to cause the side walls to turn outwards, the bent corners to crack or the bottom surface to warp, so that the welding quality and the integral strength of the door plate are affected. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an automatic welding workstation for a door plate of a switch cabinet, which solves the problems in the background art. The automatic welding workstation for the door plates of the switch cabinets comprises a workbench, plasma arc welding equipment, a transverse plate, a clamping assembly and a rotary introducing assembly, wherein the workbench is used for bearing the door plates to be welded, the plasma arc welding equipment is arranged above the workbench and used for welding the connection parts of the door plates and the reinforcing ribs in a shape like a Chinese character 'ji', the transverse plate is arranged above the workbench, the clamping assembly is arranged below the transverse plate and used for clamping the reinforcing ribs, and the rotary introducing assembly can drive the transverse plate to horizontally rotate around the axis of the transverse plate to an inclined angle in a descending stroke, so that the reinforcing ribs clamped by the clamping assembly are introduced into the inner side of the door plate in an inclined posture, and after the reinforcing ribs are completely introduced, the transverse plate is controlled to reversely rotate and reset, so that the reinforcing ribs are attached to the door plate. Further, the diaphragm upper end is provided with the movable plate, and diaphragm upper end mid-mounting has the pivot of being connected with the movable plate rotation, and the extension board is all installed at the both ends about the movable plate, has seted up the arc wall on the extension board, and the arc track in arc wall uses the pivot axis as the centre of a circle, and the traveller is installed to the position that the diaphragm upper end corresponds the arc wall, traveller and arc wall sliding fit. Further, the rotary guide-in
