Problems solved by technology

[0002] At present, the volume of mechanical products tends to be miniaturized, and the parts are also developing in the direction of "small", "thin" and "light". Therefore, more and more thin ring parts are encountered in the process of processing. Due to these The rigidity of the part itself is insufficient, and the flexibility is sufficient. Conventional clamping not only cannot meet the processing accuracy, but also causes shape errors due to the elastic deformation of the part due to the clamping force, which has become one of the difficulties in processing.

Embodiment Construction

[0016] (1) Do not use force when locking the hexagon socket screw, just tighten it slightly, because the workpiece will be deformed by compression and the radial dimension after processing will be too small;

[0017] (2) The locking cover is screwed too tightly to prevent the workpiece from being deformed by force;

[0018] (3) The feed amount is controlled at 0.03-0.08mm according to the workpiece material;

[0019] (4) The rotating speed is controlled at 400~1200r / min according to different workpiece materials.

Abstract

The invention discloses a processing technology for thin annular parts. The problems that the out-of-tolerance of size and geometric tolerance of the thin annular parts is easily caused in the traditional processing technology are solved. The processing technology for thin annular parts comprises the following steps of: installing a core shaft, and turning an outer circle; sleeving the outer circle and turning an inner circle; carrying out aging treatment. The processing technology for the thin annular parts is reasonable, and the finishing quality of the thin annular parts is improved.

Description

technical field [0001] The invention relates to the field of processing technology, in particular to the processing technology of thin annular parts. Background technique [0002] At present, the volume of mechanical products tends to be miniaturized, and the parts are also developing in the direction of "small", "thin" and "light". Therefore, more and more thin ring parts are encountered in the process of processing. Due to these The rigidity of the part itself is insufficient and the flexibility is sufficient. Conventional clamping not only cannot meet the processing accuracy, but also causes shape errors due to the elastic deformation of the part due to the clamping force, which has become one of the difficulties in processing. [0003] Thin ring parts are most prone to dimensional deformation caused by chuck positioning and thermal deformation caused by excessive feed. Based on this situation, avoid directly positioning the workpiece itself when designing the tooling, a...
