An Automatic positioning and processing system for three-dimensional printed product is for the three-dimensionally printed product transferring to a device for subsequent processing procedures quickly, and the corresponding device may quickly process and position the product by a reference point. The positioning comprising positioning device in the X, Y and Z axes so as to complete processing procedures and improve the accuracy of processing. And it is especially applicable for products having irregular shapes, such as artificial bones, human implants and surgical tools. The present invention may be helpful in mechanical automatic positioning so as to complete the processing of high-precision biological printed products.

When pressurized fluid is not supplied into or discharged from the first channel 28a of the piston rod 28, that is, when the first channel 28a is isolated from the outside, the cylinder tube 22 is in a stopped state. At this time, fluid inside the first cylinder chamber 36a is compressed, and the pressure is increased accordingly to match the sum of the weights of the cylinder tube 22, the table 18, and the workpiece W.

The present invention discloses an overhead machining device based on a portable 5-DOF full parallel module. The overhead machining device based on a portable 5-DOF full parallel module comprises: a sliding table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF full parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table.

A machine tool comprises first and second rotary machine axes (10,16) which are parallel and mounted on a base in fixed locations relative to the base, a linear machine axis (8) which is carried by the first rotary machine axis, and a rotary positioning mechanism (30) which is carried by the linear machine axis, wherein the rotary positioning mechanism provides rotation about a support rotational reference axis (32) that is parallel to the first and second rotary machine axes. A further machine tool includes a linear positioning mechanism (40) which is carried by the linear machine axis that provides linear movement parallel to the linear machine axis. The rotary and/or linear positioning mechanisms enable the workzone of the machine tool to be extended and/or reconfigured.

The present disclosure provides a system and method relating to work tables. The system comprises a table that attaches to a drill press. Specifically, the present disclosure relates to a drill press table with a fence and optionally a drawer, a vacuum assembly, flip stop assemblies, and various other components. Various operation of using the table are described herein.

A support mechanism includes a fixed body, a rotating unit, a moving unit and a driving unit. The rotating unit is rotationally mounted to the fixed body. The moving unit, disposed at the fixed body, includes a ball screw spline shaft, a ball screw nut and a ball spline nut. The ball screw nut and the ball spline nut are both rotatably disposed at the ball screw spline shaft moved together with the rotating unit. The driving unit, disposed at the fixed body, includes a first driving member and a second driving member to rotate the ball screw nut and the ball spline nut, respectively. With different rotation pairs of the ball screw nut and the ball spline nut to the ball screw spline shaft, the ball screw spline shaft is driven to move, and the ball screw spline shaft is further to move the rotating unit.

A redundant positioning table device with six or fewer degrees of freedom having four modular legs extended from a base to a table, each legs being with three levels and the same types of joints. In one embodiment, the bottom joint is planar and active, the middle joint is prismatic and passive, and the top joint is spherical and passive. In another embodiment, the bottom joint is prismatic and passive, the middle joint is planar and active, and the top joint is spherical and passive. Fewer than six degrees of freedom is achieved by reducing the number of degrees of freedom of designated joints.
