The utility model discloses automatic drilling frock of automobile semi-axis ring flange, including the anchor clamps body of vertical arrangement, set up in the holding ring of anchor clamps body upper end, set up in the hydraulic pressure corner hydro-cylinder of anchor clamps body upper end and set up the clamp plate on the piston rod of hydraulic pressure corner hydro-cylinder, the axial of holding ring is perpendicular with the horizontal plane, be provided with the location tang with the ring flange complex on the automobile semi-axis on the holding ring; the clamp body and the positioning ring are provided with gaps, and the gaps are used for the automobile half shaft to enter and exit the clamp body and the positioning ring along the horizontal direction;

the automatic drilling tool for the automobile half-shaft flange plate further comprises a tool magazine arranged beside the clamp body, wherein the tool magazine comprises a support, a plurality of U-shaped tool placing blocks arranged on the support, a rotary hydraulic cylinder arranged on the support and a baffle arranged on a rotating shaft of the rotary hydraulic cylinder and used for protecting the tool magazine.

Further, be provided with on the anchor clamps body with holding ring complex locating pin, the holding ring passes through the bolt fastening on the anchor clamps body.

The utility model has the advantages that:

1. the utility model discloses automatic drilling frock of car semi-axis ring flange, it adopts and erects mode location and fixed car semi-axis, and is provided with the breach on the anchor clamps body and the holding ring, is convenient for put into or take out car semi-axis along the horizontal direction translation, and it adopts hydraulic pressure corner hydro-cylinder to carry out automatic clamping simultaneously, very big improvement the efficiency of loading and unloading work piece.

2. The utility model discloses automatic drilling frock of car semi-axis ring flange, it is provided with the tool magazine, and this drilling frock and machining center cooperation are drilled, and drilling rotational speed is fast, and drilling efficiency is high, can better assurance drilling quality; the tool magazine is arranged, so that the drilling tool can adapt to the processing of automobile half shafts of different varieties and different apertures; meanwhile, the tool magazine is provided with a stop block, so that the tools can be prevented from being damaged by splashed scrap iron and the like.

3. The utility model discloses automatic drilling frock of car semi-axis ring flange when the car semi-axis of different varieties need be processed, only need with original holding ring pull down change suitable holding ring can, easy operation is swift, good to the car semi-axis adaptability of different varieties.
