The invention discloses high-accuracy-positioning motor machining drilling equipment. A plurality of clamping plates are vertically arranged on a base and define a workpiece mounting position; a fastening sleeve is arranged outside all the clamping plates in a sleeving mode and mounted by being matched with the outer walls of the clamping plates; a pressing plate is horizontally disposed on the upper portion of the fastening sleeve and arranged outside the multiple clamping plates in a sleeving mode through a middle opening; positioning plates at the inner edge of the pressing plate penetratethrough gaps between the corresponding two adjacent clamping plates to extend into the position above the workpiece mounting position; and a pressing portion of a drill bit presses the tops of the positioning plates and a drilling portion penetrates through the opening in the pressing plate to extend into the position below the pressing plate. By means of the high-accuracy-positioning motor machining drilling equipment which is optimally designed, motor special-shaped parts are clamped through a clamping device, when the drill bit performs drilling downwards, the pressing portion of the drillbit presses down the positioning plates on the pressing plate, then vertical pressing and positioning of to-be-machined workpieces are achieved, the reliability of matching between a bit tool and theworkpieces during drilling is guaranteed, and the drilling accuracy is improved.
