Abstract

The invention discloses a large-scale adjustable frame structure welding fixture, comprising a fixture base, a quick-replacing structure, a fixing unit, a pressing device, a positioning device and a workpiece, wherein the base is composed of a square frame and a guiding rail, the quick-replacing structure is composed of a quick-replacing connector, a connecting plate and a reinforcing rib, the fixing unit is composed of a cross beam fixing unit and a longitudinal beam fixing unit, the pressing device comprises an air cylinder and a replaceable press block, the positioning device is composed ofa positioning plate and a sliding base, and the workpiece comprises a cross beam and a longitudinal beam. The large-scale adjustable frame structure welding fixture is combined with the currently used welding fixture of a welding work station, so that structural innovative design is realized, and the carrying capacity of 1500kg is realized by using an overturning positioner. By adopting the quick-replacing mechanism, different fixtures can be removed from and mounted on the overturning positioner, so that the mounting and replacing of the fixture are more convenient.

Description

technical field [0001] The invention relates to a welding fixture of an automatic robot welding workstation, in particular to a large adjustable frame structure welding fixture. Background technique [0002] Welding has a wide range of applications in industrial production, known as the "tailor" of industrial manufacturing, and is widely used in industries such as automobiles, shipbuilding, aerospace, petrochemicals, machinery manufacturing, and energy and power. In the past, welding products often had appearance defects such as burrs and slag inclusions, as well as manufacturing defects such as welding looseness, pores, and cracks. The fundamental way to solve these manufacturing problems is to prevent improper operation of welders in the production process. Due to the shortage of labor force, instability of manual operation, and the decline in the cost of automation equipment such as welding robots, manufacturing companies have taken automated welding workstations and auto...
