ABSTRACT:
An indexing apparatus includes a casing, an indexing unit, a gripping unit, a dynamic unit and a driving unit. The indexing unit includes a connecting rod journalled in the casing and having a top portion extending out of the casing, an indexing disc sleeved rigidly on the connecting rod, and several circumferentially equidistant limiting devices provided along the periphery of the indexing disc. The gripping unit slides along the periphery of the indexing disc and can engage with one of the limiting devices so as to prevent the gripping unit from sliding relative to the indexing disc. The dynamic unit supplies power to the indexing unit. The driving unit transfers motion of the dynamic unit to the indexing unit so as to rotate the indexing disc. In a case where the gripping unit is engaged with one of the limiting devices, the movement of the dynamic unit disengages the gripping unit from the limiting device so as to rotate the indexing disc until the gripping unit engages with the next limiting device.
