Abstract

The invention relates to a welding robot device for a penetration intersection between a cylinder and a cone. In the prior art, the number of semiautomatic or automatic welding robots for welding between a cylinder and a conical pipe is small, a rotary body intersecting line cutting welding device is provided in the patent with the number of 201010176136.X, and but the welding robots mentioned above have the defects of being multiple in freedom degree, complex in structure, difficult to control, high in cost and the like. The invention relates to the welding robot device for a penetration intersection between a cylinder and a cone. According welding robot device for a penetration intersection between a cylinder and a cone, one end of a rotary shaft is connected with an external rack through a first revolute pair, the other end of the rotary shaft is connected with a sliding rod through a prismatic pair, one end of a connecting rod is connected with a sliding rod through a second revolute pair, the other end of the connecting rod is connected with a side link through a third revolute pair, the other end of the side link is connected with the external rack through a cylindrical pair,and a welding gun device is fixedly connected to the sliding rod. The welding robot device for a penetration intersection between a cylinder and a cone has the advantages of being simple in structure, convenient to control, wide in application range and the like.

Description

technical field [0001] The invention relates to a welding robot device, which provides a new type of welding robot device for intersecting a cylinder and a cone. Background technique [0002] Pressure vessels are widely used in industry, agriculture, construction, chemical industry, construction and other fields, especially in the field of petrochemical industry, accounting for about 50% of the total use of pressure vessels. Pressure vessels are also widely used in industrial sectors, such as various energy accumulators in construction machinery, auxiliary machines of various power machinery, various gas and liquefied gas storage tanks used in cities and enterprises, and various large-scale engineering pipelines Wait. Pressure vessels play an important role in industrial production and life, and are an important part of the national economy. [0003] In welding production, due to the complex spatial shape of each part of the pressure vessel, in addition to the round pipe j...
