[0002] Vertical machining center is a widely used processing equipment, which can perform high-precision processing operations on various parts. The processing of some complex parts may require the fixture to achieve specific actions such as flipping and rotation to meet the processing angle requirements of different processing surfaces. Traditional fixtures require multiple clamping and adjustment, which takes a long time to clamp and is prone to clamping errors, reducing processing accuracy and making it difficult to meet the needs of efficient and precise processing. The hydraulic system can provide stable power output to ensure that the fixture moves smoothly during the flipping process without impact or shaking, which is crucial to ensuring processing accuracy.

[0003] Therefore, we propose a hydraulic flip machining fixture for vertical machining centers, which can stably hydraulically flip, adjust at multiple angles, facilitate multi-faceted machining, accurately position, ensure machining accuracy, rotate to change faces, and stably clamp, reducing manual assembly errors and meeting the needs of efficient and precise parts processing.
