Abstract

The invention discloses a processing method of a stepped type drilling template, a guide sleeve, a mold and a compressor rotor spindle. The template comprises a first main body; the first main body is stepped and cylindrical, a first through hole is formed in the center of the first main body, a plurality of second through holes are formed in the periphery of the first through hole, the circle centers of the plurality of second through holes are jointly on a first circumference, a plurality of third through holes are formed in the periphery of the first through hole, the circle centers of the plurality of third through holes are jointly on a second circumference, the first through hole, the first circumference and the second circumference are concentric circles, and the diameter of the second circumference is more than that of the first through hole and is less than that of the first circumference. The guide sleeve comprises a second main body, the second main body is stepped and cylindrical, and a fourth through hole is formed in the center of the second main body and used for accommodating a drilling screw rod; a flange is arranged at one end of the second main body, and the external diameter of the flange is more than the internal diameter of each of the second through holes. The mold is formed by combining the template and the guide sleeve. The method is realized based on the mold. The template is high in operation precision and simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a method for processing a stepped drilling template, a guide sleeve, a mold and a compressor rotor main shaft. Background technique [0002] The compressor unit is the "heart equipment" that provides power for the entire coal chemical process. The compressor unit refers to the production of 100,000 standard cubic meters of oxygen products per hour. [0003] The rotor shaft used in the compressor has a total length of 7.6 meters, a maximum diameter of more than 1.2 meters, and a total weight of 27 tons. It consists of three shafts. The three-section spindle is connected after finishing machining, which is the first domestic technology. As the rotor of the compressor, the balance accuracy of the rotor is extremely high, so the three-section main shaft is connected by a 20-φ50H7 pin-hole connection, so that the centers of the three-section main shaft can be on a straight line t...
