A flexible combined welding assembly line

Abstract

The invention discloses a flexible combined welding assembly line which can be used for welding all directions of a workpiece and randomly increasing or deleting a welding station according to production requirements, and has a simple structure and low manufacturing cost. The flexible combined welding assembly line comprises a conveying mechanism and a plurality of follow fixtures which are operated in the conveying mechanism and are used for clamping the workpiece; the conveying mechanism comprises a front end module, a plurality of middle modules and a tail end module which are detachably connected together, two forward direction conveying chains which penetrate through all the modules and are arranged in parallel, and two returning conveying chains which are located under the two forward direction conveying chains and are arranged in parallel; the conveying mechanism is provided with one or more of a deflection-free welding device, an overturning welding device and a rotary welding device according to welding production requirements; one or more welding devices with each type can be arranged according to the production requirements.

Description

technical field [0001] The invention relates to a welding device, in particular to a flexible combined welding line. Background technique [0002] At present, traditional robot welding mostly adopts the form of a workstation, that is, one or several robots form a workstation, and the workstation exists independently of each other as an isolated processing unit. The disadvantages are: 1. Due to the limitation of the working range of the robot, the workstation 2. The position and quantity of the positioner in the workstation are fixed and cannot be rearranged according to the processing requirements, so the scope of application is narrow; 3. For some welding requirements are high and processing is difficult Larger parts may need to be repositioned multiple times in the production process to meet the requirements. It needs to be equipped with an expensive multi-dimensional positioner. The manufacturing cost is high, and multiple displacements will reduce the efficiency of weldi...
