Description

Technical Field

[0001] The utility model relates to the technical field of curved surface parts processing, in particular to a high-speed precision multi-axis curved surface parts processing device. Background Art

[0002] Improving the efficiency and accuracy of complex surface machining has always been an urgent problem to be solved in CNC machining. Most complex surface parts are processed by multi-axis CNC machine tools. The existing fixtures for processing complex surface parts mostly use hydraulic indexing fixtures and locating pins on mobile mounting seats to achieve positioning and clamping. The structure is complex and it is not possible to flexibly clamp parts of different specifications during use. The operation is cumbersome. In addition, the parts after positioning and clamping will move with the progress of CNC machining. The vibration of the CNC machine tool itself and the stress generated by the tool on the parts during machining cause the machined parts to have displacement deviations on the original position, resulting in reduced machining accuracy.

[0003] An existing patent (publication number: CN214816815 U) discloses a multi-axis CNC machining device for curved surface parts, which adjusts the screw-in length of the adjusting screw in the screw hole seat, uses the rubber pad on the base plate set at the end of the adjusting screw, squeezes the rubber pad to press the curved surface part, and the vibration generated during processing causes the support spring and the return spring to deform, absorbing the excess vibration to ensure the processing accuracy. It can clamp parts of different sizes for processing and reduce the influence of the vibration generated by the processing on the parts, resulting in low processing accuracy.

[0004] However, the above technical solution still has certain defects. When clamping special-shaped workpieces, the rubber pad is in contact with the workpiece, and the workpiece may fall during processing. The staff needs to reinstall the clamp, which may cause damage to the workpiece body when it falls, and the staff is required to adjust the adjusting screws at both ends, which reduces the work efficiency of the staff. For this reason, a high-speed precision multi-axis curved surface parts processing device is proposed. Utility Model Content
