Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-8, a device for smoothly cutting and synchronously clamping cable and wire comprises a chassis 1, a snap ring 2 movably connected to the surface of the chassis 1, a fixed disc 3 movably connected to the back of the snap ring 2, an arc groove 4 formed on the outer ring surface of the snap ring 2, an adjusting screw 5 movably connected to the inside of the arc groove 4, a positioning block 6 movably connected to the inside of the arc groove 4, a cutting knife 7 movably connected to the front of the fixed disc 3, a groove ring 8 formed on the front surface of the fixed disc 3, a clamping rod 9 fixedly connected to the front surface of the cutting knife 7, a straight groove 10 formed on the inner ring surface of the snap ring 2, a driven disc 11 movably connected to the back of the chassis 1, a sliding groove 12 formed on the back surface of the driven disc 11, a clamping jaw 13 movably connected to the groove of the sliding groove 12, a threaded disc 14 movably connected to the front of the driven, the inner part of the first driving gear 15 is movably connected with a first driven gear 16, the back surface of the snap ring 2 is movably connected with a second driving gear 17, and the inner part of the second driving gear 17 is movably connected with a second driven gear 18.

Wherein the chassis 1, the snap ring 2 and the fixed disk 3 are all in a ring structure and share the same central axis respectively. The chassis 1, the snap ring 2 and the fixed disk 3 all rotate around the same axis.

Wherein the cutting knife 7 is simultaneously clamped in a straight groove 10 of the clamping ring 2 and a groove ring 8 arranged on the front surface of the fixed disc 3 through a clamping rod 9 fixedly connected with the surface. The snap ring 2 is rotated, and the cutting knife 7 is driven to do eccentric rotation movement far away from or close to the central axis under the sleeve joint of the straight groove 10 through the driving of the clamping rod 9 and the limiting of the groove ring 8.

Wherein, the arc groove 4, the adjusting screw 5, the positioning block 6, the cutting knife 7, the clamping rod 9, the straight groove 10, the sliding groove 12 and the clamping jaw 13 are respectively provided with five parts and are uniformly distributed by taking the central axis of the chassis 1 as a reference. A plurality of cutting knives 7 and rather than the mechanism of being connected between can effectively disperse the pressure distribution when cutting wire and cable, reach smooth cutting's purpose, can also effectively reduce the operation rotation angle of snap ring 2 simultaneously, reduce work load. In addition, the design of a plurality of jack catchs 13 can promote the ability of holding with to wire and cable, avoids appearing not hard up problem when the cutting.

The upper and lower surfaces of the claw 13 are respectively provided with gear teeth, and the gear teeth are movably clamped with the screw thread arranged on the surface of the threaded disc 14 and the sliding groove 12 arranged on the surface of the driven disc 11. The jaws 13 can move in a diverging or converging manner with reference to the central axis, in the grooves of the runner 12 of the threaded disc 14.

The inner ring surface of the driving gear I15 and the outer ring surface of the driven gear I16 are respectively provided with gear teeth which are meshed and connected with each other, and the driving gear II 17 and the driven gear II 18 are completely the same as the above structures, but the synchronous connection positions are completely opposite. The driving gear I15, the driven gear I16, the driving gear II 17 and the driven gear II 18 can make the same movement mode and purpose, but the movement rhythm is opposite to achieve the effect of synchronously clamping the electric wire and cable in the cutting process.

Wherein the positioning block 6 is fixedly connected on the front surface of the chassis 1.

The working principle is as follows: the chassis 1 is rotated clockwise, the clamping ring 2 is movably connected with the chassis 1 in a rotating mode, the adjusting screw 5 is movably connected with the clamping ring 2, the clamping ring 2 and the adjusting screw 5 can synchronously move in the same direction along with the chassis 1 at the moment, the adjusting screw 5 can push the positioning block 6 to synchronously move at the moment, and the clamping ring 2 can synchronously move along with the chassis 1 as the positioning block 6 is movably connected with the fixed disk 3 in a rotating mode. In a similar way, the straight groove 10 is driven to rotate clockwise by the synchronous drive in the rotating process of the snap ring 2, and meanwhile, under the limiting action of the groove ring 8, the sleeve joint clamping rod 9 guides the cutting knife 7 to do eccentric rotation motion taking the central axis as the center of a circle, namely, the distance and the angle between the cutting knife 7 are increased at the moment. On the contrary, when the cutting tool rotates anticlockwise, the motion process of the structure with the changed state in the motion process is completely opposite, and the electric wire and the electric cable are positioned on the central axis so as to achieve the purpose of cutting the parquet of the cutting tool.

Because the threaded disc 14 is movably connected with the chassis 1 in a rotating way, the chassis 1 can drive the threaded disc 14 to synchronously rotate in the same direction when rotating, and when the threaded disc 14 rotates clockwise, the jaws 13 are synchronously guided to perform gathering movement close to the central axis in the sliding groove 12 of the driven disc 11 through threads on the surface of the threaded disc and gear teeth arranged on the surfaces of the jaws 13, so that the electric wires and cables can be clamped. On the contrary, when the thread disc 14 made anticlockwise rotation, it is the same with above-mentioned process principle, but the motion is tricky completely opposite, and claw 13 is outside dispersion motion in step, can loosen electric wire and cable.

The inner side of the driving gear I15 and the outer side of the driven gear I16 are respectively provided with double gear teeth and single gear teeth, the gear teeth on the surfaces of the driving gear I15 and the driven gear I16 are in an engaged state in an initial state, the inner side of the driving gear II 17 and the outer side of the driven gear II 18 are also respectively provided with double gear teeth and single gear teeth, the driving gear I15 and the driving gear II 17 are in a non-engaged state in the initial state, and the driving gear I15 and the driving gear II 17 are movably connected with the chassis 1, so that the driving gear I15 and the driving gear II 17 can be driven to synchronously move. Because driving gear 15 and screw disk 14 swing joint, can know through above-mentioned structure, because the teeth of a cogwheel on driving gear 15 and the 16 surfaces of driven gear are intermeshing state under initial condition, so can drive screw disk 14 motion earlier when chassis 1 moves, when moving to the inboard of driving gear two 17 and driven gear two 18 meshing, snap ring 2 just begins to rotate, and the motion of jack catch 13 is earlier than the motion of cutting knife 7 promptly, otherwise, the motion of cutting knife 7 is earlier than the motion of jack catch 13 during anticlockwise rotation.

In addition, through changing the position of adjusting screw 5 in arc groove 4 inside, can change the motion stroke of locating piece 6, the motion stroke of locating piece 6 is big more, and the biggest distance and the size between cutting knife 7 are big more promptly, applicable in the wire and cable of bigger diameter, otherwise, the motion stroke of locating piece 6 is little, and then go distance and the size between individual cutting knife 7 and be little to this further avoid wire and cable to appear rocking problem in cutting a mouthful department.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
