Description

Technical Field

[0001] The invention relates to the technical field of cable processing, in particular to a cable cutting device. Background Art

[0002] A cable is a conductor used to transmit power or signals, consisting of one or more insulated wires, usually wrapped in a protective sheath.

[0003] At present, when stripping or installing cables, the cables need to be placed in a fixed position, and at least one person holds the cables while another person strips or installs them. In this way, the height of the cables cannot be adjusted during the operation, and the operator can only operate while bending over, which is extremely inconvenient. In addition, the work efficiency is also very low.

The applicability of the cable clamp is combined with the cable cross-section setting, and it can be applicable to cables with a cross-section of 50-400mm2; at the same time, the design of the clamp is innovatively optimized, and the cable can be quickly and stably fixed on the workbench. A workbench can quickly complete the stripping and installation of cable terminals of various voltage levels. However, although the above-mentioned device can assist in positioning the cable for auxiliary production and installation, the positioning structure is in a fixed single position during its use, and the height can only be adjusted according to demand during its use.

[0017] Compared with the prior art, the present invention has the following beneficial effects: Firstly, in the present invention, by driving the turntable to rotate through the first motor, the transverse guide rail can be driven to rotate auxiliaryly, thereby facilitating the adjustment and driving the top positioning mechanism to rotate. By starting the second motor, the threaded rod on the inner side of the transverse guide rail can be driven to correspondingly drive the two sets of slide blocks to move relative to each other, thereby adjusting the reciprocating movement of the top positioning mechanism. By starting the third motor on the inner side of the fixed frame, the third motor drives the screw rod to rotate, and the rotation of the screw rod can drive the slide to extend and retract on the inner side of the guide frame. By adjusting the slide to extend and retract up and down, the height of the top positioning mechanism can be assisted to be adjusted, so that the device can flexibly adjust the top positioning mechanism at any position on the top of the stand, and at the same time, it is convenient to flexibly adjust the adaptation height, so that the overall device is easy to adapt to the production of cables in different positions.

[0018] Secondly, in the present invention, when the cable needs to be positioned from the bottom, the line is passed through the positioning groove. At this time, the limit spring resets and drives the connecting shaft to push the positioning block inward. The positioning block and the clamping cooperation limit block inside it contact the cable, thereby assisting in positioning the cable. At this time, the upper end of the cable can be passed through the threading groove. When the cable needs to be positioned from the top, the two ends of the cable are arranged on the inner side of the clamping frame. The first cylinder is extended and drives the movable frame to push the moving block to move on the inner side of the top guide rail, which can drive the clamping frames to move relative to each other to stably clamp the cable. In addition, its adjustable design can stably position and process cables of different thicknesses.

[0019] Thirdly, in the present invention, by arranging the cutting mechanism and the tensioning mechanism to cooperate, when the cable is positioned during use, the device can start the second cylinder to operate, and the operation of the second cylinder can assist in pushing the concave seat upward, and the upward movement of the concave seat can assist in adjusting the tensioning roller to move upward, and the upward movement of the tensioning roller can assist in contacting the fixed cable, and the cable can be assisted in penetrating by the expansion and contraction of the tensioning spring. During use, since the cable is tightened as a whole, the cable can be tightened as a whole, which can make the cable more compact and stable during production, and convenient for operation. At the same time, when cutting, it is only necessary to start the third cylinder to drive the semi-arc frame to move downward, and the fourth motor is started to drive the cutting disc to rotate while the semi-arc frame moves downward. Since the tensioning mechanism tightens the cable, the cutting disc can quickly cut the cable by contacting the cable. During use, the displacement block can be adjusted to move on the inner side of the slide rail to assist in adjusting the lateral displacement of the semi-arc frame and the cutting disc, so that the device can flexibly cut the positioned cable, which is convenient for cable production and improves the overall convenience of use of the device.

By setting the bottom positioning mechanism 3 and the top positioning mechanism 6 to cooperate, when the cable needs to be positioned from the bottom during use of the device, the handle 327 can be pulled to drive the connecting shaft 325 to pull the positioning block 326 to move.

The clamping and limiting block 328 on its inner side contacts the cable, thereby assisting in positioning the cable. At this time, the upper end of the cable can be passed through the threading groove 9. When the cable needs to be positioned from the top, the two ends of the cable can be set on the inner side of the clamping frame 65. At this time, by starting the first cylinder 62 to extend and retract, the movable frame 63 can be driven to push the moving block 64 to move on the inner side of the top guide rail 61. The mutual movement of the moving blocks 64 can drive the clamping frame 65 to move relative to each other, so that the cable can be stably clamped. In addition, its adjustable design can stably position and process cables of different thicknesses. Since the side shape of the clamping groove 66 is V-shaped and anti-slip bumps are arranged at equal intervals inside it, the anti-slip bumps on the inner side of the clamping groove 66 can be used to The device can stably fit the outer surface of the cable and can relatively stably clamp and position the cable, so that the device as a whole has good stability, which is convenient for producing and processing cables during use. By setting the cut-off mechanism 7 and the tensioning mechanism 8 to cooperate, when the cable is positioned during use, the second cylinder 82 can be started to operate, and the operation of the second cylinder 82 can assist in pushing the concave seat 84 upward, and the upward movement of the concave seat 84 can assist in adjusting the tensioning roller 85 to move upward, and the upward movement of the tensioning roller 85 can assist in contacting the fixed cable, and the extension and contraction of the tensioning spring 83 can assist in penetrating the cable. During use, since the cable is tightened as a whole, the cable can be tightened as a whole, which can make the cable more compact and stable during production, and convenient for operation.At the same time, when cutting, it is only necessary to start the third cylinder 75 to drive the semi-arc frame 76 to move downward, and start the fourth motor 77 to drive the cutting disc 78 to rotate while the semi-arc frame 76 moves downward. Since the tensioning mechanism 8 tightens the cable, the cutting disc 78 can quickly cut the cable when it contacts the cable. During use, the displacement block 72 can be adjusted to move on the inner side of the slide rail 71 to assist in adjusting the lateral displacement of the semi-arc frame 76 and the cutting disc 78, so that the device can flexibly cut the positioned cable, which is convenient for cable production and improves the overall convenience of use of the device.
