Abstract
A positioning assembly using a pair of rollers elastically connected to a holding base for clamping two cutters received in the holding base. The cutters in the holding base can be adjusted to make different blades contact and align precisely.
Claims20
A positioning assembly for positioning a plurality of workpieces, comprising:
- a holding base comprising a bottom board and a pair of parallel sidewalls extending upwards perpendicularly from opposite sides of the bottom board;
- and
- a clamping unit comprising a pair of rollers arranged in a direction parallel to the bottom board and a plurality of elastic elements, opposite ends of each roller slidably connected to the corresponding sidewalls, the elastic elements configured for applying a force onto the rollers in a direction toward the bottom board to position the workpieces on the bottom board.
A positioning assembly comprising:
- a holding base comprising a bottom board and a pair of parallel sidewalls extending upwards perpendicularly from opposite sides of the bottom board;
- and
- a clamping unit comprising a pair of rollers and a plurality of elastic elements, opposite ends of each roller slidably connected to the corresponding sidewalls, the elastic elements configured for applying a force onto the rollers in a direction toward the bottom board,
- wherein the bottom board is generally rectangular and comprises an upper surface, and a bottom surface opposite to the upper surface, the sidewalls extending perpendicular to the upper surface from opposite edges of the bottom board, and the bottom board and the sidewalls cooperatively defining a receiving space having two opposite open portions for accommodating the clamping unit;
- and
- each of the sidewalls defines two through holes, the through holes being spaced a same distance from the upper surface and being flattened elongated elliptical in shape, and the major axis of each through hole being substantially perpendicular to the upper surface.

A positioning assembly for positioning a workpiece, comprising:
- a holding base comprising a bottom board and a pair of parallel sidewalls extending from the bottom board, the sidewalls being opposite to each other, each of the sidewalls defining a sliding track;
- and
- a clamping unit comprising a roller and an elastic element, opposite ends of the roller respectively connected to the opposite sidewalls and being slidable along the sliding track to change the distance between the roller and the bottom board, opposite ends of the elastic element respectively connected to the roller and the holding base for applying a force onto the roller in a direction toward the bottom board when the roller slides at any position;
- wherein, when no workpiece is positioned by the positioning assembly, the roller is located at a lowest position defined by the sliding track;
- and
- when a workpiece is placed into the positioning assembly, the roller is forced to slide away from the bottom board by overcoming the force applied by the elastic element, and clamps the workpiece in cooperation with the bottom board.
