Tool for machining in vertical direction for machining center

The utility model relates to the field of machining, and particularly discloses a vertical machining tool for a machining center, which comprises a first fixing plate, a second fixing plate and a reinforcing plate. The first fixing plate is fixedly connected with a second fixing plate; a reinforcing plate is fixedly connected between the second fixing plate and the first fixing plate; a plurality of first fixing holes and second fixing holes are respectively formed in the first fixing plate and the second fixing plate; the speed reducer shell is arranged on the anti-falling threaded shaft in a sleeving mode, then bolts are inserted into the second fixing holes to complete fixed connection, and therefore the speed reducer shell can be kept at the vertically-upward position, then the first fixing holes are fixed to a tool of a machining center through the bolts to complete vertical assembly of the speed reducer shell, and after machining is completed, the speed reducer shell is fixed to the anti-falling threade
