[0029] Step 1: The operator first installs a plurality of pipe fittings on the outside of the pipe clamp 2, positions the outside of the pipe fittings through the symmetrically arranged pipe clamp 2, uses the conveying belt 1 to move a plurality of pipe clamps 2 and pipe fittings laterally, and when the pipe fittings move to one side of the pipe sleeve 5, the operator pushes the pipe fittings to align one end of the pipe fittings with one side of the workpiece clamping jaw 14, and then uses a plurality of air cylinders 15 to pull one side of the workpiece clamping jaw 14 to clamp and position the pipe fittings through a plurality of workpiece clamping jaws 14.

[0030] Step 2: Then, according to the diameter of the pipe fittings, the operator can adjust the size of the expansion and the depth of the hole expansion, first pull the slider 12 to drive the side positioning plate two 8 to slide on the outside of the guide groove 7 through the slider 12, and then control the size of the unfolded hydraulic cylinder 9, and finally lock the connection between the slider 12 and the side positioning plate two 8 through the bolts.
