2results about How to "Adjust the clamping force" patented technology

This invention discloses a turning and grinding device for the inner ring of a precision bearing, relating to the field of bearing grinding technology. It includes a bearing grinding box, with a first operating table fixedly installed on one side of the box. Two sets of electric slide rails are symmetrically installed on the first operating table. A second operating table is fixedly installed on one side of the first operating table, with a detection camera fixedly installed on the second operating table. A first movable seat is provided on the other side of the first operating table, and a grinding robot is detachably installed on the first movable seat. Through the coordinated use of the grinding clamping base, the detection camera, the grinding robot, and the grinding control system, the clamping force during grinding can be adaptively adjusted according to the bearing size. Simultaneously, the size of the grinding head for the inner ring can be adjusted according to different bearing sizes. Through the coordinated use of the detection camera and the grinding control system, the device identifies debris accumulation and adjusts the air cooling intensity, only activating liquid nitrogen when air cooling is saturated and the temperature continuously exceeds the standard.

This invention discloses an adaptive fixation bone marrow assembly separation device, comprising a separation tube with a gradually decreasing inner bottom space. A core is assembled inside the separation tube, and the core has multiple evenly distributed fixation channels for fixing the bone. After the outer wall of the core is in close contact with the inner wall of the separation tube, a liquid-carrying area is formed in the upper part of the separation tube, which is used to fill the irrigation fluid. When the core is inserted into the bottom of the separation tube, it is compressed and deformed. Simultaneously, the fixation channels deform synchronously and clamp the fixed bone inside. This invention uses a pressure assembly method to assemble the core in the gradually decreasing space at the bottom of the separation tube, causing the core to be compressed and deformed, which prompts the fixation channels to adaptively adjust the clamping force on the bone according to the centrifugation speed. A liquid-carrying area is formed above the core to fill the bone marrow cavity with irrigation fluid during centrifugation, achieving integration of centrifugal separation and irrigation separation, thus improving the separation effect.
