The invention relates to the technical field of a drilling and milling device and a drilling and milling method and particularly relates to a balance block drilling and milling combined clamp and a drilling and milling method thereof. The balance block drilling and milling combined clamp comprises an upper body, a lower body, an opening gasket, a nut, a positioning shaft, positioning pins, positioning holes and equally-divided grooves, wherein the upper body and the lower body are connected; the opening gasket and the nut are arranged at the center of one side of the upper body and the positioning shaft is arranged at the center of one side of the lower body; and each of the upper body and the lower body is provided with the positioning pin, the positioning hole and 35 groups of the equally-divided grooves. The balance block drilling and milling combined clamp disclosed by the invention has the advantages of simple, compact and reasonable structure, convenience and rapidness for assembling, and reliability in connection; clamping and positioning machining of two work procedures including drilling and milling of a balance block can be finished, and the precision of the balance block which is drilled and milled by the drilling and milling method is guaranteed; and the clamping operation is convenient, the machining efficiency is greatly improved and the reliability of drilling and milling the balance block is greatly improved, so that the balance block drilling and milling combined clamp and the drilling and milling method thereof are easy to use and popularize.
Description
technical field [0001] The invention relates to the technical field of a drilling and milling device and a drilling and milling method, in particular to a drilling and milling compound fixture for a balance weight and a drilling and milling method thereof. Background technique [0002] The balance weight is a part on the rotor of the traction motor of a diesel locomotive. The part has a small size, but its processing is relatively complicated. Due to the high speed of the traction motor, when the rotor is dynamically balanced in the test, in order to eliminate the unbalance, a certain amount of balance weight must be embedded in the inclined groove of the rotor shaft end for counterweight to eliminate the unbalance of the rotor. The assembly method is to embed the balance weight into the inclined surface groove of the rotor shaft end, screw the bolt into the bolt hole of the balance weight, push the balance weight upside down when screwing the bolt, so that the slopes on bot...
