Description

Tooling for processing asymmetrical rotary parts

Technical field:

The utility model relates to an asymmetric revolving body part (the part is mainly composed of two revolving bodies A and B (shown by dotted lines), and its axis L ₂ , L ₃ with reference axis L ₁ For parts with a certain angle and intersecting at point O, the rotating bodies A and B are relative to the reference axis L ₁ is asymmetric), as shown in Figure 1. A processing tool is an auxiliary processing device in mechanical processing, and belongs to the technical field of mechanical processing.

Background technique:

At present, for processing asymmetrical rotary parts on lathes, as shown in Figure 2, the basic rotary body C (symmetrical rotary body) must first be processed, and then the asymmetrical rotary body is pre-drilled based on the axis L of the basic rotary body. The two top holes of the body (the axis L connecting the two top holes ₄ There is an angle and intersects with the axis L of the basic revolution body, and the axis L found at this time ₄ is the axis of the asymmetrical body of revolution), and then use the found axis L of the asymmetrical body of revolution ₄ Machining of asymmetrical bodies of revolution. This method can be used to process asymmetric rotary parts. However, this method has high requirements on the technical level of workers, and the precision of the processed parts is low.

Utility model content:

In order to solve the problems of large errors in machining asymmetrical revolving parts in the existing method, difficult alignment and difficult machining of the axis of the asymmetrical revolving body. The utility model provides a tool for quickly aligning the axis of an asymmetrical revolving body part, which has the functions of convenient installation and time saving, and can greatly improve the machining accuracy of the asymmetrical revolving body part.

Technical solutions:

A kind of tooling used for processing asymmetric rotating body parts, using the knowledge in geometry, as shown in Figure 1, with an axis L ₁ If a fixed point O is selected as the reference and the other end rotates around the fixed end, many axes with a certain angle with the reference axis will be formed, such as L ₂ , around the axis L ₂ The rotating body formed by rotation (the rotating cone in the dotted line) is relative to the reference axis L ₁ Asymmetric gyratory (the other side is the same), according to the principle of the formation of asymmetric gyroscopic body, only the axis L of the asymmetrical gyroscopic body ₂ When it is aligned with the spindle of the machine tool, the machining of the asymmetrical rotating body can be realized, and the reference axis L at this time ₁ There is an included angle with the main shaft of the machine tool, such as the tooling body in the tooling for asymmetric rotary body processing in Figure 3, the tooling body is a cylinder, as long as the axis L of the cylinder ₅ and the asymmetric axis of revolution L ₂ coincidence, the asymmetrical rotary body can be processed, and the basic axis L of the asymmetrical rotary body part at this time ₁ has become oblique, along the cardinal axis L ₁ Directional drilling, at this time the axis of the drilled hole is L ₆ (L ₆ with L ₁ Coincidence) relative to the axis L of the tooling body ₅ It is inclined, and this hole is the centering hole of the asymmetrical gyratory. Just put the parts of the asymmetrical gyratory into the oblique hole and clamp them, and the axis L of the asymmetrical gyratory is completed. ₂ and then install the tooling and the components of the parts to be processed on the lathe together. At this time, the rotation axis L of the rotary body to be processed ₂ Always coincident with the spindle of the lathe. In this way, the processing of asymmetrical rotary parts can be realized.

Beneficial effect:

The processing cost is reduced, the requirements for workers are lowered, the operation is simple, it is not easy to make mistakes, and the processing accuracy of the parts is greatly improved. The foundation was laid for the mass production of such parts.
