Abstract

A cable processing system comprises a stripping device for stripping a segment of an outer cladding layer of a cable. The stripping device includes a support frame, and a mounting plate movably mounted on the support frame between a start position and an end position in the axial direction of the cable. The mounting plate includes a first surface and a second surface opposite to each other in an axial direction of the cable. A plurality of cutting units are mounted on the first surface of the mounting plate for cutting off the outer cladding layer in a circumferential direction of the cable. A plurality of stripping units are mounted on the second surface of the mounting plate for slicing the outer cladding layer in the axial direction.

First claim

What is claimed is:

1. A cable processing system comprising:
a stripping device for stripping a segment of an outer cladding layer between two ends of a cable, including:
a support frame;
a mounting plate movably mounted on the support frame between a start position and an end position in the axial direction of the cable and having a first surface and a second surface opposite to each other in an axial direction of the cable;
a plurality of cutting units mounted on the first surface of the mounting plate for cutting off the outer cladding layer in a circumferential direction of the cable, each of the cutting units including a first driver driving a first cutter to move in a radial direction of the cable, the first driver comprising a linear driving device having a fixed member attached to the mounting plate and a movable member movable relative to the fixed member along an axis extending in the radial direction of the cable; and
a plurality of stripping units mounted on the second surface of the mounting plate for slicing the outer cladding layer in the axial direction.

2. The cable processing system according to claim 1 , wherein the plurality of cutting units are symmetrically mounted on the first surface of the mounting plate, and the plurality of stripping units are symmetrically mounted on the second surface of the mounting plate.

3. The cable processing system according to claim 1 , wherein the plurality of cutting units include two cutting units arranged opposite each other in a radial direction of the cable.

4. The cable processing system according to claim 3 , wherein each of the first cutters is formed with a concave semicircular cutting edge for cutting the outer cladding layer.

5. The cable processing system according to claim 4 , wherein the semicircular cutting edge of the first cutter has a radius equal to an inner diameter of the outer cladding layer of the cable such that the first cutter cuts the outer cladding layer of the cable without cutting the inner layer of the cable beneath the outer cladding layer cut.

6. The cable processing system according to claim 1 , wherein each of the cutting units further includes a first cutter holder connected to the first driver, the first cutter being detachably mounted on the first cutter holder.

7. The cable processing system according to claim 1 , wherein the plurality of stripping units include four stripping units evenly spaced apart from each other around the axis of the cable.

8. The cable processing system according to claim 7 , wherein each of the stripping units includes a second cutter formed with a straight cutting edge extending in the axial direction of the cable.

9. The cable processing system according to claim 8 , wherein each of the stripping units further includes a second driver configured to drive the second cutter to move in a radial direction of the cable.

10. The cable processing system according to claim 9 , wherein each of the stripping units further includes a second cutter holder connected to the second driver, the second cutter being detachably mounted on the second cutter holder.

11. The cable processing system according to claim 10 , wherein each of the stripping units further includes two rollers rotatably mounted on the second cutter holder, the two rollers being symmetrically mounted on a front side and a rear side of the second cutter, each of the rollers having a concave arc contact surface to be pressed against the outer cladding layer of the cable.

12. The cable processing system according to claim 10 , wherein the second driver includes an air cylinder or a hydraulic cylinder having a second cylinder body and a second piston rod, the second cylinder body fixed on the second surface of the mounting plate and the second piston rod connected onto the second cutter holder.

13. The cable processing system according to claim 1 , wherein the support frame includes a first vertical support plate and a second vertical support plate arranged opposite to each other in the axial direction of the cable, and a plurality of first guide rods connected between the first vertical support plate and the second vertical support plate, the plurality of first guide rods extend in the axial direction of the cable and pass through the mounting plate such that the mounting plate is movable along the first guide rods.

14. The cable processing system according to claim 13 , further comprising two third drivers arranged on two opposite sides of the mounting plate in the radial direction of the cable, the two third drivers driving the mounting plate to move between the start position and the end position in the axial direction of the cable.

15. The cable processing system according to claim 14 , wherein each of the third drivers includes an air cylinder or a hydraulic cylinder having a third cylinder body and a third piston rod, the third cylinder being connected to the mounting plate by a right-angle connection piece, the cable processing system further including a first fixed plate and a second fixed plate, two ends of the third piston rod are connected to the first fixed plate and the second fixed plate respectively such that the third cylinder is movable upwardly in the axial direction of the cable.

16. The cable processing system according to claim 15 , further comprising a second guide rod having two ends connected to the first fixed plate and the second fixed plate respectively, the second guide rod extending in the axial direction of the cable and passing through the third cylinder to guide the third cylinder to move along the second guide rod.

17. The cable processing system according to claim 1 , further comprising a straightening device for straightening the cable before the outer cladding segment is stripped.

18. The cable processing system according to claim 17 , wherein the straightening device includes:
a horizontal fixed bracket;
a horizontal movable bracket arranged opposite to the horizontal fixed bracket;
a row of first rollers rotatably mounted on the horizontal fixed bracket and arranged in a row in the axial direction of the cable; and
a row of second rollers rotatably mounted on the horizontal movable bracket and arranged in a row in the axial direction of the cable, each of the first rollers and the second rollers has a rotation axis extending in a vertical direction and a concave arc surfaces in contact with the outer cladding layer of the cable, the horizontal movable bracket is movable horizontally in a radial direction of the cable such that the cable is clamped between the row of first rollers and the row of second rollers.

19. The cable processing system according to claim 18 , wherein the straightening device further includes:
