Caterpillar track assembly assembling equipment

Caterpillar track assembly assembling equipment structurally comprises a mounting base, an assembling air cylinder is arranged in the middle of the upper end of the mounting base, a positioning sleeve is arranged on the edge of the upper end of the mounting base, a positioning rod is movably connected to the positioning sleeve in a sleeving mode, an assembling plate is arranged at the output end of the assembling air cylinder, and the end of the positioning rod is connected with the assembling plate. A plurality of caterpillar track parts are fixed to a workbench, then positioning parts of fixing pins are inserted into positioning grooves, an air pump is driven to operate, so that air pressure is input into an external expansion type clamp through an air pipe, an acting block in the external expansion type clamp moves, inclined acting force is generated on the end of a clamping barrel, and the end of the clamping barrel is subjected to external expansion type deformation; the groove opening in the positioning
