Abstract: An aeronautical aluminum alloy minimum-quantity-lubrication milling machining device includes a machine tool worktable and spindle connected with a machine tool power system. The spindle is connected with a tool holder that is fixed with a cutting tool. The machine tool worktable is provided with a machine tool fixture, the tool holder is connected with a minimum-quantity-lubrication mechanism, the machine tool fixture includes a fixture body that is fixedly provided with a limit block for contact with two adjacent side surfaces of a workpiece, the fixture body is provided with a plurality of clamping elements capable of pressing the workpiece against an upper surface of the fixture body, and a top of the clamping element is provided with a detection member for detecting a relative position between the clamping element and the spindle. The device can avoid interference and contact between a nozzle and the clamping element.

Abstract: An automobile hub fixture includes a fixture body and a positioning apparatus. The fixture body includes a fixed platform and a plurality of clamping claws arranged at intervals in a circumferential direction of the fixed platform. The clamping claws are configured to clamp an outer rim of a hub. The plurality of clamping claws are connected to a driving member by using a linkage, and the driving member drives the clamping claws to radially move along the fixed platform. The positioning apparatus includes a movable platform slidably connected to the clamping claws. A positioning module configured to position an inner rim or the outer rim of the hub is mounted to the movable platform. The machining device includes a fixture, a machine tool, and a minimal quantity lubrication apparatus. The production line includes a machining device, a loading system, a loading and unloading manipulator, and a catching table.

Abstract: The present invention relates to a powder dry-pressing molding device and method.

Abstract: The present invention relates to a bone dilator designed for treating compression fracture of vertebral body, and fractures of cancellous bones at other sites. The bone dilator comprises a head portion, a neck portion, a connecting tube, a handle and a rotary hilt. The head portion embodies different shapes for use at different locations. When the rotary hilt is rotated clockwise and the pull rod is pulled backwards, the upper and the lower parts of the head portion keep parallel or at a predetermined angle during expanding. When the rotary hilt is rotated counterclockwise and the pull rod is pushed forwards, the head portion and the neck portion completely join together, the distal end of the pull rod and the bar stays are completely or partially retracted in grooves inside the head portion and the neck portion.

Abstract: The present invention relates to a bone dilator designed for treating osteoporotic compression fracture of vertebral body, fractures of cancellous bones at other sites and certain traumatic or pathologic compression fracture of vertebral body.
