The invention provides a radial cutting system for cables, which can realize the processing of reaction force cones and is suitable for the processing of the reaction force cones with different sizes. As shown in fig. 1, the cable cutting system includes a cutting support 1, a planetary gear set 2, a first driving member 3, a second driving member 4, and a cutting tool 5, wherein the planetary gear set 2, the first driving member 3, and the second driving member 4 are all mounted on the cutting support 1, the first driving member 3 and the second driving member 4 can jointly drive the planetary gear set 2 to rotate, and the cutting tool 5 can be driven by the planetary gear set 2 to rotate and move radially.
As shown in fig. 2 to 5, the planetary gear set 2 includes a fixed gear 21, a carrier 22, planet gears 23, a ring gear 24, a cutter drive gear 25, and a rack 26, wherein:
the fixed gear 21 is rotatably disposed on the cutting support 1, and can be driven by the first driving member 3 to rotate, and preferably, a first transmission gear 7 is fixed at an output end of the first driving member 3, the first transmission gear 7 is engaged with a power input gear 6, and the power input gear 6 is fixedly connected to one end of the fixed gear 21 to drive the fixed gear 21 to rotate at the same speed. In this embodiment, only one end of the fixed gear 21 away from the power input gear 6 is provided with teeth, and the rest is a polished rod structure.
The planet carrier 22 is fixedly sleeved on the fixed gear 21 and can rotate along with the fixed gear 21, an annular groove is formed in the outer side of the planet carrier 22, a plurality of rotatable gear shafts 27 are evenly distributed in the annular groove in the circumferential direction, a planetary gear 23 is fixed on each gear shaft 27, and the planetary gear 23 is meshed with the internal teeth of the fixed gear 21 and the annular gear 24 simultaneously.
The ring gear 24 can be driven by the second driving member 4 to rotate, and for example, the output end of the second driving member 4 is fixedly connected with the second transmission gear 8, and the second transmission gear 8 is meshed with the external teeth of the ring gear 24. The second transmission gear 8 is driven to rotate by the second driving member 4, so that the ring gear 24 rotates.
The cutter driving gear 25 may be rotated in synchronization with the planetary gears 23, and preferably, the cutter driving gear 25 may be fixedly connected to an end of the gear shaft 27 penetrating the planet carrier 22, and when the ring gear 24 rotates the planetary gears 23, the planetary gears 23 rotate the cutter driving gear 25 via the gear shaft 27. It can be understood that, in the present embodiment, the number of the gear shafts 27 and the planet gears 23 may be multiple, and the gear shafts and the planet gears are uniformly distributed on the planet carrier 22 in the circumferential direction.
The tool drive gear 25 can engage with a rack 26, the rack 26 being fixed to the cutting tool 5, and the rack 26 can drive the cutting tool 5 to move radially when the tool drive gear 25 rotates. In this embodiment, the cutting tool 5 is radially disposed, and when moving radially, can realize the adjustment of the cutting depth of the cable. The number of cutting tools 5 is the same as the number of racks 26 and arranged circumferentially.
Preferably, in order to better realize the movable support of the cutting tool 5, the radial cable cutting system of the present embodiment further includes a tool mounting seat 9, the tool mounting seat 9 is fixedly mounted on one side of the planet carrier 22, the tool driving gear 25 can be placed in the tool mounting seat 9, and accordingly, the cutting tool 5 and the rack 26 can slide in the radial direction in the tool mounting seat 9.
In the present embodiment, the revolution speed and the rotation speed of the planetary gear 23 are influenced by the rotation speeds of the ring gear 24 and the fixed gear 21 and the corresponding number of gear teeth. The planetary gear 23 rotates at a speed n when the gear module is the same2And revolution speed nHSpeed n of rotation of the ring gear 241And number of gear teeth z1And the number of revolutions n of the fixed gear 213And gear diameter z3Satisfies the following relation:
when the rotational speed n of the ring gear 24 is above1And number of gear teeth z1And the number of revolutions n of the fixed gear 213And gear diameter z3Satisfies n1z1=n3z3At this time, the planetary gear 23 revolves without rotating. The planet gear 23 drives the cutter driving gear 25 through the gear shaft 27, and since the planet gear 23 does not rotate, the rack 26 is not displaced in the radial direction, that is, the feed depth of the cutting cutter 5 is not changed. If n is such that1z1≠n3z3Then, the planetary gear 23 has a self-rotation motion, and finally the feed depth of the cutting tool 5 is changed to adjust to a desired cutting depth. The purpose of regulating and controlling the revolution speed can also be achieved by adjusting the rotating speeds of the first driving piece 3 and the second driving piece 4, and the larger the revolution speed is, the larger the rotating speed of the cutting tool 5 is, the smoother the cut reaction force cone is.
That is, the present embodiment can control the feeding depth and the rotation speed of the cutting tool 5 by controlling the first driver 3 and the second driver 4, so that the machining apparatus of the present embodiment can machine reaction force cones with different requirements.
