Problems solved by technology

[0002] The high-pressure rotor of the engine needs to be dynamically balanced, and the parts cannot be directly supported by the balancing machine, and the rotor shaft diameter is double-cylindrical centered. The traditional tooling design needs to heat the parts before assembling. After assembly, it needs to return to room temperature. The problem of long cycle time and waste of energy, in addition, there are scratches on the surface of the machine parts during the interference fit sub-packaging process, especially the coating surface is easy to cause damage

Embodiment Construction

[0024] like Figure 1-2 A fixture for balancing a double-cylindrical pressurized rotor is shown, including positioning bushing a1, balancing bushing 2, positioning bushing b3, screw a4, plunger 5, bolt 6, screw b7, adapter plate 8, and nut 9 and spacer 10;

[0025] The balance bush 2 is sleeve-shaped, and the inner wall is provided with a plurality of installation grooves;

[0026] The adapter plate 8 is fixed on the large end of the balance bush 2 through the bolt 6, and the adapter plate 8 is used for balancing the rotation transmission;

[0027] The balance bush 2 is provided with a positioning bush a1 and a positioning bush b3 to form a double cylinder;

[0028] The positioning bush a1 and the positioning bush b3 correspond to the radial installation grooves on the inner wall of the balance bush 2, and are used to pressurize and clamp the front journal of the high-pressure rotor;

[0029] The plunger 5 is filled into the radial installation groove on the inner wall of t...

Abstract

The invention discloses a double-cylindrical-surface pressurizing type clamp for rotor balancing. The clamp comprises a positioning bushing a, a balancing bushing, a positioning bushing b, screws a, plungers, a bolt, screws b, an adapting plate, a nut and gaskets. The balancing bushing is in the shape of a sleeve, and a plurality of mounting grooves are formed in the inner wall of the balancing bushing. The adapting plate is fixed to the large end of the balancing bushing through the bolt, and the positioning bushing a and the positioning bushing b are arranged in the balancing bushing to formdouble cylindrical surfaces. The positioning bushing a and the positioning bushing b correspond to the mounting grooves in the radial direction of the inner wall of the balancing bushing in position.The plungers are poured into the mounting grooves in the radial direction of the inner wall of the balancing bushing. Each screw b is arranged at the upper end of the corresponding plunger, the nut is screwed on a part and clamped on the inner wall of the balancing bushing, and thus device movement is prevented. The inner wall of the balancing bushing is further provided with cavity channels communicating with the positioning bushing a and the positioning bushing b. The screws a penetrate through the outer wall of the balancing bushing and abut against the cavity channels. The gaskets are arranged between the screws a and the cavity channels. The cavity channels are filled with liquid plastic.

Description

technical field [0001] The invention relates to the technical field of a steel supporting fixture for balancing a high-pressure rotor, in particular to a double-cylindrical pressurized rotor balancing fixture. Background technique [0002] The high-pressure rotor of the engine needs to be dynamically balanced, and the parts cannot be directly supported by the balancing machine, and the rotor shaft diameter is double-cylindrical centered. The traditional tooling design needs to heat the parts before assembling. After assembly, it needs to return to room temperature. The problem of long cycle time and waste of energy. In addition, the interference fit sub-package process has scratches on the surface of the machine parts, especially the coating surface is easy to cause damage. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a double-cylindrical pressurized rotor balancing fixture, the specifi...
