The invention discloses a vehicle windshield wiper machining device. The vehicle windshield wiper machining device comprises a function plate, press units, binding units, a delivering unit, a locating box, cushion blocks, occulting bars, a conveying belt, a connecting frame, an electric rail, a screwing base, a toothed block, a bristle opening, a brush rod box, connecting openings and a bristle box. The vehicle windshield wiper machining device has the advantages that the vehicle windshield wiper machining device is provided with multiple sets of press units and binding units, multiple windshield wipers can be subjected to machining operation simultaneously, and the machining efficiency is improved; the locating box is divided into the brush rod box and the bristle box, the connecting openings of which the upper portions are opened are formed in the brush rod box and the bristle box, brush rods and bristle can be bound through the binding units, the positions of the brush rods and the bristle are constant during binding, and the brush rod and the bristle are convenient to take down after binding is completed; a right angle triangular structure is arranged at one side of each each occulting bar, the impetus is the highest, and meanwhile, when the use of the locating box is finished, the locating box is easy to drop out; the screwing base and the toothed block are both connected with the electric rail through the connecting frame, and the electric rail can supply power to the connecting frame and also provide a limiting effect for longitudinal running of the connecting frame.
