Abstract

The invention discloses a hand-cranking type welding positioner for welding a large rack. The hand-cranking type welding positioner comprises a foundation, a hand-cranking device, a driving device, a front end supporting seat device, a work platform device and a back end supporting seat device, wherein the hand-cranking device, the driving device, the front end supporting seat device, the work platform device and the back supporting seat device are fixed on the foundation; the hand-cranking device comprises a rotating disc, a driving shaft, a driving gear, a hand-cranking device bearing and a hand-cranking handle; the driving device comprises a driven gear, a driving screw, a driving nut, a gear rack, a driving device bearing and an end cover; the front end supporting seat device comprises a big gear, a front end supporting bearing, a driving shaft, a front end cover, a back end cover and a front supporting seat flange plate; and the work platform device comprises a flange plate and a platform welding structure body. The hand-cranking type welding positioner for welding the large rack is simple and practical, is convenient to operate and adjust, is driven by hand-cranking, can freely rotate in the range of minus 90 degrees to 90 degrees and can be self-locked; and with the adoption of the hand-cranking type welding positioner, the welding size precision of the rack is guaranteed, and the interchangeability can be guaranteed; and the depending degree to the technical level of a welding operator is reduced, and requirement functions are achieved with low cost.

Description

technical field [0001] The invention belongs to the field of special equipment design for welding manufacturing technology, and in particular relates to a hand-operated welding positioner for large-scale frame welding. Background technique [0002] Construction machinery and equipment are widely used in national infrastructure construction, such as pavers, milling machines in road construction and maintenance machinery, wet spraying machines in bridge and tunnel machinery, rock drilling rigs, loaders and excavators in earthwork machinery , Boom pump trucks in concrete machinery, etc., the fuselage frame or boom are relatively large structural weldments, which are key components in the vehicle structure, and the overall welding quality directly affects the assembly of the vehicle , life, reliability and stability. The welding of large frame is one of the difficulties in the manufacture of structural parts. The difficulties in manufacturing are mainly reflected in the followi...
