Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of threaded lifting repeated positioning clamping devices, in particular to a thin-walled disc part finishing threaded lifting repeated positioning clamping method and device. BACKGROUND

[0002] The thin-walled disc part finishing threaded lifting repeated positioning clamping device refers to a repeated positioning clamping device adopted when processing thin-walled disc parts with small wall thickness. Threaded lifting is adopted to provide control force, thereby reducing the possibility of deformation angle of the thin-walled disc part during processing.

[0003] Considering that various sizes of workpieces need to be processed during processing, the sizes of clamping pieces required by workpieces of different sizes are different during processing, so some clamping devices with special functions can be applied.

[0004] Generally, the traditional positioning clamping device fixes the inner wall and the outer side of the workpiece, but the fixed size of the inner wall is often fixed, and the outer side is often fixed in a downward pressing manner. This method makes the clamping size fixed, thereby unable to process workpieces of multiple sizes, and the downward pressing type fixing cannot effectively limit the outer side of the workpiece (disc type). At the same time, a large amount of debris will be generated during processing, and the traditional method is to use external equipment (such as a fan) to blow away the debris. The external equipment needs to be installed and transported separately, and the drive for using the external equipment needs to be increased, thereby increasing the installation cost. At the same time, the use of multiple drives requires separate setting of cooling and maintenance equipment, thereby increasing the overall use cost.

[0005] In summary, the thin-walled disc part finishing threaded lifting repeated positioning clamping method and device are needed to solve the above problems. SUMMARY
