<p>A process and device for producing a bearing eye or a transverse perforation in the clevis of the actuating rod of a brake power booster. The assembled brake power booster is inserted in a locking frame of the device, the clevis being retained at a cutting tool provided in a locking frame at a desired design distance of the clevis from the fixation flange of the booster casing. Upon insertion of the booster in the locking frame, the legs of the clevis are punched by a cutting punch so that in a single process step, a transverse punch hole or perforation to receive the pivot pin of the brake pedal is made maintaining a close tolerance to the desired design distance, i.e. independently of the specific position of mounting of the actuating rod and independent of the distance between the end of the clevis and the fixation flange of the booster casing.</p> |
