The invention relates to a thin-walled cylinder body welding and shaping clamp which comprises a supporting ring, expansion blocks, guide assembles and force transmission assemblies. The force transmission assembly comprises a first base and a transmission screw which is installed in a screw hole formed in the first base. Each guide assembly comprises a second base and a guide pin which is installed in a through hole formed in the second base in an inserted mode. The number of the expansion blocks is at least three. The number of the force transmission assemblies is equal to that of the expansion blocks. Each force transmission assembly set is provided with two guide assembly sets. All the force transmission assemblies are installed on the top face of the supporting ring away from one another by the same angle. The two guide assembly sets of each force transmission assembly set are symmetrically arranged on the two sides of the force transmission assembly set. One expansion block is assembled with one force transmission assembly set. All the expansion blocks are connected with the guide pins of the guide assemblies on the two sides of the force transmission assemblies which are assembled with the expansion blocks.
Description
technical field [0001] The invention belongs to a welding and shape-calibrating jig, in particular to a jig and a shape-correcting jig used when welding along the longitudinal direction of a thin-walled cylinder or around the periphery of the thin-walled cylinder is required. Background technique [0002] When welding parts along its longitudinal direction or around its periphery on the thin-walled cylinder formed by sheet metal processing, it is easy to deform the cylinder, so clamps are needed during welding, and clamps are required to correct the shape after welding. The quality, operation convenience and cost of fixtures directly affect the production cost and processing quality of sheet metal parts. Existing fixtures are usually only designed for a certain process, and are only suitable for a certain process, and the structure is complex, heavy, and inconvenient to operate, so the application area is narrow, the utilization rate is low, and the production cost is high, ...
