Abstract

A cable straightening device includes a plurality of cable straightening units connected in series. Each of the cable straightening units includes a base, a pair of rows of rollers mounted on the base and cooperating with each other to define a pressing path extending in a row direction, and a mounting frame disposed on at least one end of a pair of opposite ends of the base in the row direction. A cable is pressed by the rows of rollers while passing through the pressing path. Any two adjacent cable straightening units are assembled together at the mounting frame of each so that center lines of the pressing paths of two adjacent cable straightening units are aligned with each other.

First claim

What is claimed is:

1. A cable straightening device, comprising:
a plurality of cable straightening units connected in series, each of the cable straightening units including:
a base including a first base, a second base mounted on the first base, a plurality of support frames mounted on the first base, and a movable frame mounted on the second base, the movable frame includes a main body portion movably mounted on the second base and a plurality of support arms extending parallel from the main body portion, a plurality of second rollers in the second row of rollers are each rotatably mounted at an end of one of the support arms;
a pair of rows of rollers mounted on the base and cooperating with each other to define a pressing path extending in a row direction, a cable being pressed by the rows of rollers while passing through the pressing path, a first row of rollers in the rows of rollers are mounted on the support frames and a second row of rollers in the rows of rollers are mounted on the movable frame, the support frames are movable along the first base in a transverse direction transverse to the pressing path and the movable frame is movable along the second base in the transverse direction to move the first row of rollers and the second row of rollers toward and away from the pressing path on opposite sides of the pressing path, the base includes an adjustment device mounted in the second base and configured to push the movable frame to move in a transverse direction perpendicular to the row direction to adjust a distance between an outer edge of the second rollers in the second row of rollers and a center line of the pressing path, the adjustment device includes a drive shaft rotatably mounted in the second base and a drive wheel mounted at an end of the drive shaft and having an axis offset from that of the drive shaft, the drive shaft is rotatable to drive the movable frame to move in the transverse direction by the drive wheel; and
a mounting frame disposed on at least one end of a pair of opposite ends of the base in the row direction, any two adjacent cable straightening units are assembled together at the mounting frame of each so that center lines of the pressing paths of two adjacent cable straightening units are aligned with each other.

2. The cable straightening device of claim 1 , wherein the mounting frames of the two adjacent cable straightening units are arranged such that the respective rows of rollers of the two adjacent cable straightening units press the cable in different radial directions.

3. The cable straightening device of claim 1 , wherein in each of the cable straightening units, the mounting frame has a plurality of mounting portions arranged so that the base is mountable in different postures to allow the cable to be pressed by the two rows of rollers in different radial directions of the cable.

4. The cable straightening device of claim 3 , wherein the mounting frame is formed as an annular frame, a center of an inscribed circle of the annular frame is located on the center line of the pressing path.

5. The cable straightening device of claim 1 , wherein each of the support frames has a substantially L-shaped profile and includes a horizontal arm mounted on the first base by a first connection member and a vertical arm perpendicular to the horizontal arm and configured to rotatably support a first roller in the first row of rollers.

6. The cable straightening device of claim 5 , wherein the first base has a plurality of first mounting grooves extending perpendicular to the row direction, the horizontal arm has an adjustment hole through which the first connection member passes to mount the horizontal arm in the first mounting groove so that a distance between an outer edge of the first roller and the center line of the pressing path is adjustable.

7. The cable straightening device of claim 1 , wherein the adjustment device includes an operating portion protruding from the second base at an end of the drive shaft opposite to the drive wheel and operably driving the drive shaft to rotate.

8. The cable straightening device of claim 1 , wherein the adjustment device includes a positioning portion adapted to prevent the drive shaft or the drive wheel from being rotated.

9. The cable straightening device of claim 8 , wherein the positioning portion includes a screw rod protruding into a drive groove formed in the main body portion from outside and operably abutted against an outer edge of the drive wheel to prevent the drive wheel from being rotated.

10. The cable straightening device of claim 1 , wherein the second base has a plurality of partition portions, each of the support arms passing through a gap between two adjacent partition portions.

11. The cable straightening device of claim 10 , wherein the base includes a holding portion arranged on the partition portions and connected to the second base to hold the movable frame on the second base.

12. The cable straightening device of claim 1 , wherein the base includes a plurality of elastic members each mounted on the second base at a first end and abutted against a side of the first base at a second end opposite the first end so that the movable frame is moved toward the pressing path against an elastic force of the elastic member.

13. The cable straightening device of claim 1 , wherein the first base is formed with a plurality of mounting grooves extending substantially perpendicular to the row direction, the support arms are each mounted in one of the mounting grooves.

14. The cable straightening device of claim 1 , wherein the rollers in the first row of rollers are arranged to be spaced apart from the rollers in the second row of rollers in each of the cable straightening units.

15. The cable straightening device of claim 1 , wherein the plurality of cable straightening units is three cable straightening unit, a pair of adjacent cable straightening units presses the cable in a pair of radial directions perpendicular to each other.
