Flexible welding production line for side wall plate of automobile

Abstract

The invention relates to a flexible welding production line for a side wall plate of an automobile, which is used for improving the flexible production capacity of an autobody welding line body, and comprises a clamp body, a trolley, a frame, a drive mechanism and a PLC (programmable logic controller) control system. The clamp body is installed on the trolley which is connected with the drive mechanism. The trolley is controlled by the PLC control system and dragged by the drive mechanism to reciprocate on a track of the frame to convey the clamp and workpiece of the welding line body. The drive mechanism is arranged on the frame which is fixed on the level ground. The flexible welding production line for the side wall plate of the automobile provided by the invention has the advantages of stable performance, strong universality and high degree of automation, and according to the flexible welding production line, not only is the work efficiency of the welding operation improved remarkably and the production pace of the factory is ensured, but also the flexible production capacity of the welding line body is improved, the capital investment on devices is lowered, the period of new products in batch production is shortened, and large economic benefits is brought for enterprises.

Description

technical field [0001] The invention relates to a welding production line body, which is especially suitable for the welding production of automobile body side panels, and belongs to the technical field of welding equipment. Background technique [0002] Body welding is an important process in the production process of automobiles, and it is generally completed on the body of the welding production line. At present, most of the fixtures used in the body side panel welding production line are special fixtures with low flexibility and can only perform welding operations for a single vehicle type. Although the conversion of two similar models can be realized by switching the fixture support through the cylinder, many fixture units need to be added. The fixture units are too dense and easily interfere with the welding tongs, resulting in diversion and operation difficulties; Models need to be developed at the same time in order to reduce the risk of fixture design; in addition,...

At present, most of the fixtures used in the body side panel welding production line are special fixtures with low flexibility and can only perform welding operations for a single model

Although the conversion of two similar models can be realized by switching the fixture support through the cylinder, many fixture units need to be added. The fixture units are too dense and easily interfere with the welding tongs, resulting in diversion and operation difficulties; Models need to be developed at the same time in order to reduce the risk of fixture design; in addition, during the operation of the existing body side welding assembly line, there is relative movement between the workpiece and the fixture, which can easily damage the surface of the workpiece and affect product quality
