Welding equipment and welding method for bottom frame of screw machine

Abstract

The invention relates to the field of welding, in particular to welding equipment and method for a bottom frame of a screw machine, the welding equipment comprises a tool clamp, a three-axis positioner and a welding robot device, the tool clamp is arranged at the output end of the three-axis positioner, and the welding robot device is arranged on one side of the three-axis positioner; the tool clamp is used for positioning and pressing a chassis workpiece to be welded; the three-axis position changing machine is used for changing the position of the tool clamp; the welding robot device is used for welding the underframe workpiece; the tool clamp comprises a bottom plate, a supporting frame, a side edge facing block, a left side edge flattening assembly, a right side edge flattening assembly, a front-back connecting plate pressing assembly, a left-right connecting plate pressing assembly, a right connecting plate pressing assembly, a corner transition plate positioning assembly and a corner transition plate clamping assembly, the output end of the three-axis position changing machine at least can move left and right, turn left and right and rotate in the horizontal plane. The position accuracy of each workpiece is ensured, welding is facilitated, and the quality of the chassis is improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding device and a welding method for a screw machine bottom frame. Background technique [0002] The bottom frame of the screw machine mainly plays the role of supporting, fixing and protecting the screw unit. Its structure is the mutual splicing of several sheet metal parts, usually by welding. In practical application, the bottom frame of the screw machine is required to have sufficient strength to support the parts of the screw machine. Therefore, the number of sheet metal parts of the bottom frame is large and the connection is complicated, which makes it difficult to correct when welding the bottom frame. The positioning of each component leads to deformation of the welded chassis structure, which cannot effectively carry the screw unit. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a welding equipme...
