75 results about "Normal postures" patented technology

Posture, normal, n the configuration of the body in the upright position, which varies considerably among individuals. However, normal posture can be described as follows: the shoulder, pelvis, and eyes are level; the sagittal plane is between the feet, and the line of gravity passes through the center of gravity at the lumbosacral joint.

Normal alignment method based on parallel mechanism

The invention discloses a normal alignment method based on a parallel mechanism, and belongs to the field of normal precision control. A device used by the normal alignment method comprises the parallel mechanism, a cross slide table, four laser displacement sensors and an end effecter, wherein the parallel mechanism comprises a fixed platform and a movable platform connected through a connecting rod; the end effecter is mounted on the movable platform of the parallel mechanism; the fixed platform of the parallel mechanism is mounted on the cross slide table; and the laser displacement sensors are mounted on the end effecter. The method comprises the following steps: firstly, a parallel mechanism coordinate system and a tool coordinate system are built, and an anticipant normal posture of the end effecter is calculated through distance values detected by the laser displacement sensors; and finally, an adjustment amount of the parallel mechanism is obtained through inverse solution of deviation from a present posture to the anticipant posture under the condition of guarantee the invariability of a virtual knife point position so as to realize normal alignment. The device used by the normal alignment method has the advantages of good rigidity, high bearing capacity, simple inverse solution algorithm and high precision, and can quickly realize the normal alignment of the end effecter.

Ship bilge keel positioning and mounting method

ActiveCN106516001AOptimize the segmented construction processReduce installation difficultyVessel designingBilgeKeel
The invention provides a ship bilge keel positioning and mounting method. A bilge keel is mounted on an outer curved plate which is positioned in a bilge section. The method includes steps: S1, marking a positioning joining line on the outer plate, and marking a bilge keel mounting position line according to the positioning joining line and the bilge keel; S2, adopting a three-roll plate bending machine for linear curvature processing of the outer plate to form the outer curved plate; S3, using a moulding bed for transporting and positioning the outer curved plate; S4, mounting the bilge keel on the outer curved plate to form a combined section; S5, positioning and mounting the combined section on the bilge section according to the positioning joining line. At a bilge keel mounting stage, after completion of a large section group, curvature processing of the outer plate of the bilge section is performed before mounting of the bilge keel. A normal-posture faceup installation way of the bilge keel is optimized into a horizontal faceup installation way to lower installation difficulty. Bilge keel installation precision is optimized from rough installation to accuracy control, subsequent reworking is avoided due to angle control of the bilge keel, and the moulding bed guarantees linear precision of the outer curved plate in a placement and transport process to avoid subsequent reworking.
