Detailed Description

The principles and features of the present invention are described below with examples given for the purpose of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1-5, the present embodiment provides a cutting device for processing an optical cable skin, which comprises a fixing frame 1 and a cutter rest rod 4, wherein a positioning mechanism is arranged on the fixing frame 1, a cutting mechanism 5 is arranged at one end of the cutter rest rod 4, the cutter rest rod 4 is slidably connected with the fixing frame 1, and the cutter rest rod 4 can move to the position where the cutting mechanism 5 is close to or far from the positioning mechanism and is positioned.

When the cutter bar 4 moves to be close to the positioning mechanism, the optical cable can be clamped and cut into the surface of the optical cable, so that the whole cutting device (in the direction shown by an arrow in fig. 5) rotates around the axis of the optical cable, and the surface of the optical cable can be cut. The cutting device is simple in structure, convenient to operate, light and convenient for operators to carry about compared with the existing cutting device.

Wherein, mount 1 is C shape structure, and positioning mechanism and knife rest pole 4 set up respectively at the both ends of C shape structure, and positioning mechanism and cutting mechanism 5 set up relatively.

On the basis of the technical scheme, the positioning mechanism is a roll shaft 6, the roll shaft 6 is rotatably arranged on the fixing frame 1, and the axis of the roll shaft is perpendicular to the moving direction of the tool rest rod 4.

The optical cable is clamped by the cutting mechanism 5 and the roll shaft 6, when the cutting device is rotated to cut the optical cable, the roll shaft 6 can roll around the optical cable, and the cutting device is flexible to rotate.

On the basis of the technical scheme, two roll shafts 6 are arranged, the two roll shafts 6 are arranged side by side at intervals, and the track of the cutting mechanism 5 moving along with the tool rest rod 4 is positioned between the two roll shafts 6.

As shown in fig. 5, the two roll shafts 6 and the cutting mechanism 5 are used for clamping and positioning the optical cable, so that the optical cable is accurately positioned, and the position is not easy to deviate.

On the basis of the technical scheme, the tool rest device further comprises a screwing device 2, wherein the screwing device 2 is in transmission connection with the tool rest rod 4 and is used for driving the tool rest rod 4 to move when the screwing device 2 rotates.

The precession device 2 drives the cutter bar 4 to linearly move through the rotation action, and the whole structure is compact.

On the basis of the technical scheme, the rotary screw-in type rotary screw-in device further comprises a dial 7 and an indication arrow 8, wherein the dial 7 is rotatably arranged on the fixed frame 1, and the indication arrow 8 is fixedly connected with the screw-in device 2 and points to scales on the dial 7.

When the existing cutting device cuts and removes the cable skin, the cutting depth cannot be controlled according to actual use requirements. The dial 7 is rotatable to rotate the dial 7 to the 0 scale in alignment with the indicator arrow 8 when the cutting mechanism 5 is in contact with the cable skin. When the precession device 2 rotates again and drives the cutter bar 4 to move towards the positioning mechanism, the scale mark of the dial 7 pointed by the indication arrow 8 is the depth of the cutting mechanism 5 cutting into the surface of the optical cable. The scheme can indicate the depth of the cutting mechanism 5 cutting into the surface of the optical cable through the dial 7 and the indication arrow 8, and the cutting depth can be controlled according to the scale of the dial 7.

Specifically, the dial 7 is coaxially provided with the precession device 2, and the scale on the dial 7 is provided along the circumference thereof.

The precession device 2 adopts any mechanism capable of driving the cutter bar 4 to linearly move through a rotation action.

One embodiment of the precession device 2 is: the screwing device 2 comprises a stud 11, the stud 11 is rotatably arranged on the fixing frame 1, one end of the stud 11 is in threaded transmission with the other end of the tool rest rod 4, and the tool rest rod 4 is provided with a circumferential rotation limit.

By rotating the stud 11, the stud 11 linearly reciprocates along the axial direction of the stud 11 by driving the cutter bar 4 through threads. Because the stud 11 is in threaded connection with the tool rest rod 4, after the stud 11 rotates in place, the positioning of the tool rest rod 4 can be realized by the threaded structure under the condition that the stud 11 does not rotate by external force.

For the circumferential rotation limit of the cutter rest rod 4, optionally, the cutter rest rod 4 is prismatic, the fixing frame 1 is provided with a prismatic hole matched with the prismatic hole, the other end of the cutter rest rod 4 is slidably arranged in the prismatic hole, and the cutter rest rod 4 can only axially move along the prismatic hole and cannot rotate around the axis of the prismatic hole, so that the circumferential rotation limit is realized; or, the tool rest rod 4 is provided with a key (such as a spline or a flat key, etc.), the other end of the tool rest rod 4 is slidably arranged in the through hole of the fixing frame, the side wall of the through hole of the fixing frame 1 is provided with a bar-shaped key slot in sliding fit with the key, and the tool rest rod 4 can move linearly along the axial direction under the guidance of the key and the key slot.

Further, the screwing device 2 further comprises a screwing handle 10, and the screwing handle 10 is fixedly connected with the other end of the stud 11. A screw-in handle 10 is provided to facilitate handling of the stud 11.

Specifically, the stud 11 has an axial limit. In one specific example, the screwing device 2 further comprises a nut 3, a limit nut is fixed in the middle of the stud 11, as shown in fig. 3, the nut 3 is in threaded connection with the fixing frame 1 and buckles the limit nut in the fixing frame 1, so that the stud 11 is prevented from moving downwards along the axis, and meanwhile, the screwing handle 10 is abutted to the lower end of the fixing frame 1, so that the stud 11 can be prevented from moving upwards along the axis. Thereby, axial limiting of the stud 11 is achieved. Alternatively, the axial limit can be realized by a limit nut fixed in the middle of the stud 11 by a stepped hole or a gasket and other structures arranged in the fixing frame 1.

In particular, the indication arrow 8 is fixed to the outer wall of the screw-in handle 10 and is disposed in the radial direction thereof.

Specifically, according to the pitch of the stud 11, the relation between the rotation angle of the stud 11 around the axis and the moving distance of the tool rest lever 4 can be converted, and the moving distance of the tool rest lever 4 under the corresponding angle is marked on the circumference of the dial 7, so that the scale of the dial 7 is formed.

Another embodiment of the precession device 2 is: the screwing device 2 comprises a stud 11, the stud 11 is in threaded connection with the fixing frame 1, one end of the stud 11 is rotatably connected with the tool rest rod 4 (for example, through bearing connection, or the stud 11 is provided with an annular bulge along the circumferential direction, and the tool rest rod 4 is provided with an annular groove, and the annular bulge is clamped in the annular groove and can rotate along the annular groove). In this way, although it is also possible to achieve a linear movement of the cutter bar 4 and a cable cutting. However, the stud 11 also moves linearly relative to the mount 1, which is inconvenient for reading the dial 7. The first embodiment of the precession means 2 is therefore the preferred solution.

On the basis of the technical scheme, the cutting mechanism 5 comprises an annular blade 9, the annular blade 9 is rotatably arranged at one end of the tool rest rod 4, and the rotation axis of the annular blade 9 is perpendicular to the moving direction of the tool rest rod 4.

The annular blade 9 is installed in an annular and rotatable mode, and the design can enable rolling friction to be generated between the annular blade 9 and the cable sheath when the cable sheath is cut, so that smooth cutting is facilitated.

Specifically, a groove-shaped notch is formed in one end of the tool rest rod 4, and the annular blade 9 is rotatably installed in the groove-shaped notch through a pin shaft.

On the basis of the technical scheme, an anti-skid sleeve is fixed on the outer wall of the fixing frame 1.

An anti-skid sleeve is arranged on the outer wall of the fixed frame 1, so that the fixed frame 1 is convenient to grasp and cut.

The invention also provides a cutting method, which is realized by adopting the cutting device for processing the optical cable epidermis, and comprises the following steps:

and placing the optical cable between the positioning mechanism and the cutting mechanism 5, moving the cutter bar 4 until the cutting mechanism 5 cuts into the surface of the optical cable by a preset depth, and rotating the cutting device around the axis of the optical cable until the surface of the optical cable is cut.

When the cutter bar 4 moves to be close to the positioning mechanism, the optical cable can be clamped and cut into the surface of the optical cable, so that the whole cutting device is rotated around the axis of the optical cable, and the surface of the optical cable can be cut. The cutting method is convenient to operate.

The cutting method specifically comprises the following steps:

s1, rotating a screw-in handle 10 to drive a stud 11 to rotate, converting the rotation force into axial thrust through screw engagement, enabling the stud 11 to drive a cutter bar 4 to move, and enabling an annular blade 9 to approach a roll shaft 6;

s2, placing the optical cable to be cut and peeled between the two roll shafts 6, and continuing to rotate the precession handle 10, so that the cutter frame rod 4 drives the annular blade 9 to move until the annular blade 9 abuts against the surface of the optical cable;

s3, rotating the dial 7 to align the 0 scale on the dial with the indication arrow 8;

s4, holding the optical cable by one hand to stabilize the optical cable, and calculating a preset depth required to be cut according to the thickness parameters of the outer skins of the optical cables with different types and specifications; observing the distance scale value indicated by the indication arrow 8 on the dial 7, and rotating the screwing handle 10 until the scale of the indication arrow 8 pointing to the dial 7 is a preset depth value;

s5, rotating the cutting device around the axis of the optical cable. Because the cable is stationary, the annular blade 9 completes an annular cut of the cable skin after rotation.
