Description

Technical Field

[0001] The present invention relates to the field of bearing housing blade assembly, and particularly to an assembly process method for the blades of an air compressor bearing housing. Background Art

[0002] An air compressor relies on the interaction force between a rotating impeller and an air flow to increase the gas pressure. At the same time, the air flow generates acceleration to obtain kinetic energy, and then the air flow decelerates in a diffuser to convert the kinetic energy into pressure energy. During the compression process, the gas flow is continuous. The air compressor bearing housing is located at the center of the box body, and its function is to fix the radial bearing and the rotor. To ensure the continuity of the air flow, high requirements are put forward for the installation dimensions of the bearing housing blades.

[0003] Generally, for the assembly of the blades of an air compressor bearing housing, lines are generally drawn for each blade on a conical cylinder, and the blades are installed on the conical cylinder according to the drawn lines. This method has very low efficiency, and it is very difficult to ensure the positioning dimensions of the blades, which not only affects the production quality of the air compressor box body but also prolongs the production cycle, and can no longer meet the requirements of the current manufacturing of the air compressor bearing housing.

[0004] Therefore, it is necessary to provide a new assembly process method for the blades of an air compressor bearing housing to solve the above technical problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides an assembly process method for the blades of an air compressor bearing housing.

[0006] The assembly process method for the blades of an air compressor bearing housing provided by the present invention includes a bearing housing, a tooling, and blades. The bearing housing includes a tooling plane, an inner line of a semi-circular ring, an outer line of a conical cylinder, a lower line of a middle dividing panel, and the surface of the conical cylinder. The tooling includes an inner line of a circle and a lower line of a circle, and the method includes the following steps:

[0007] S1. Determine the outer dimensions of the tooling according to the projections of the inner line of the semi-circular ring, the outer line of the conical cylinder, and the lower line of the middle dividing panel on the tooling plane. Determine the positions of the mounting holes for the blades in the tooling according to the projection of the blades on the tooling plane. After determining the relevant dimensions of the tooling, design a drawing based on these dimensions and perform blanking;

[0008] S2. Place the bearing housing on its side on a platform;

[0009] S3. Fix the tooling on the tooling plane with a fixture;

[0010] S4. Pass the blades through the mounting holes and install them perpendicular to the tooling plane and fix them to the surface of the conical cylinder by spot welding;

[0011] S5. Loosen the fixture, remove the tooling, and install reinforcement;

[0012] S6. Weld the blades.

[0013] Preferably, in the method for determining the position of the mounting holes of the blades in step S1, since in the normal direction of the tooling plane, the projection of the blade on the surface of the conical cylinder coincides with the projection of the blade on the tooling plane, and the outer shape of the mounting hole is slightly larger than the outer shape of the blade to allow the blade to pass through.

[0014] Preferably, the thickness of the tooling is selected to be greater than or equal to ten millimeters to ensure that the blades are installed perpendicular to the tooling plane as a whole.

[0015] Preferably, the method for fixing the tooling on the tooling plane in step S3 is as follows: Align the inner circular line and the lower circular line of the tooling with the inner circular line of the semi-circular ring and the lower line of the middle dividing panel respectively. The tooling is closely attached to the tooling plane and fixed by a fixture.

[0016] Preferably, in step S5 for installing reinforcement, the reinforcement is to connect the blades in sequence using round steel with a diameter of twenty millimeters.

[0017] Preferably, in step S6 for welding the blades, the welding sequence is from both sides to the middle, alternating left and right.

[0018] Compared with the prior art, the assembly process method of the air compressor bearing seat blades provided by the present invention has the following beneficial effects:

[0019] The present invention provides an assembly process method for the air compressor bearing seat blades. The position of the mounting holes of the blades in the tooling is determined according to the projection of the blades on the tooling plane. After determining the relevant dimensions of the tooling, design the graphics according to these dimensions and perform blanking. Then pass the blades through the mounting holes and install them perpendicular to the tooling plane and spot-weld them to the surface of the conical cylinder. Then weld the blades. Compared with the prior art, assembling the blades to the surface of the conical cylinder by this process method not only ensures the assembly quality of the blades on the bearing seat, but also improves the work efficiency and shortens the production cycle.
