It may include.
The apparatus may further include a fixing hole formed on a part or all of the bottom and side surfaces of the case, and a bracket fixed to the fixing hole by using a fastening member and mounted to a mounting portion of another multi-point positioning device. The positioning device can be combined with one or a plurality of other multi-point positioning devices so as to be arranged in a direction consisting of a combination of an X axis, a Y axis, and a Z axis.
In addition, the case is coupled to the base member slidably coupled to the guide member coupled to the transfer member, side plates are respectively coupled to both sides of the base member, the base member and one side of the side plate is coupled, the end of the lead screw bearing It includes a cap that is supported by, the coupling module is detachably coupled to the other side of the base member and the side plate by a fastening member, the other end of the lead screw can be supported by a bearing.
In addition, the coupling cover may be made of a transparent material to see the inside of the coupling module.
In addition, the coupling cover is provided with a fixing part fixed to the periphery of the opening, the folded portion having a reduced thickness to rotate to open the opening is formed on one side, the other side around the opening can be separated by a fastening member Is secured, and a protrusion may be formed on the bottom surface so as to fit in the opening.
In addition, the case is formed with an opening along the longitudinal direction, the cover made of a material attached to the magnetic force is arranged along the longitudinal direction in the opening portion is fixed at both ends, the transfer member is screwed to the lead screw A ball nut is mounted on the inside of the body, a magnet is mounted on the top of the body, a cover made of Teflon material is attached to the top of the body to cover the magnet, and the mounting portion has a clearance between the cover. It is fixed to the upper portion of the body to form, the cover may be inserted in the play so as to slide.
According to the multi-point positioning device according to the present invention, by combining the integrated servo motor capable of precise control, compact size and excellent assemblability enable precise control.
In addition, it is easy to assemble and install even in multiple axes, and to realize high positional accuracy.
