Based on the cutting device, the present application provides a clamping mechanism for a multi-core cable longitudinal cutting device. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] The utility model provides a clamping mechanism for a multi-core cable longitudinal cutting device, which can directly and synchronously fix multiple cable cores in the cable after the cable skin is cut, thereby improving the cutting efficiency. The clamping mechanism of the utility model includes a fixing frame and a cutting assembly arranged on the fixing frame, the fixing frame includes an outer ring 2 and an inner ring 14 arranged inside the outer ring 2 and coaxial with the outer ring 2, the inner ring 14 is for the cable to pass through, and the cable core in the cable passes between the outer ring 2 and the inner ring 14. In order to limit the position of the cables and cable cores passing through and ensure the accuracy of cutting, the utility model provides a plurality of slide grooves arranged in an array along the axis of the inner ring 14 at one end side of the inner ring 14, and the center line of the slide groove is perpendicular to the axis of the inner ring 14, and a positioning block 15 is provided in the slide groove for sliding cooperation with the slide groove, and the ends of the positioning blocks 15 located in the inner ring 14 are provided with arc-shaped cable clamps 12, and a cable clamping space for supporting the cables passing through the inner ring 14 is formed between the plurality of cable clamps 12, and a first arc piece 7 is provided at the ends of the positioning blocks 15 located between the outer ring 2 and the inner ring 14, and a second arc piece 6 corresponding to the first arc piece 7 is provided on the inner circle side of the outer ring 2, and a cable core clamping space for clamping the cable core passing through the outer ring 2 is formed between the corresponding first arc piece 7 and the second arc piece 6.

[0019] In the utility model, in order to control the cable clamp 12 to clamp the cable, the first arc piece 7 and the second arc piece 6 to clamp the cable core, a driving component is provided in the inner ring 14 to drive all the positioning blocks 15 to slide synchronously, which is used to change the distance between the positioning block 15 and the axis, thereby changing the size of the cable clamping space and the cable core clamping space.

[0020] The driving assembly includes a driving disc 13 located inside the outer ring 2 and coaxial with the axis of the outer ring 2, and a power unit for rotating the driving disc 13. The driving disc 13 is provided with a through hole for the cable to enter the cable clamping space. The driving disc 13 is provided with a guide arc hole 11 corresponding to the positioning block 15 one by one. The inner arc of the guide arc hole 11 faces the axis of the through hole. The axial spacing between the two ends of the guide arc hole 11 and the through hole gradually increases from one end to the other end. The positioning block 15 is provided with a transmission rod 1 slidably arranged in the guide arc hole 11. In the utility model, the driving disc 13 is a hollow structure, and the outer ring 2, the connecting block 3 and the inner ring 14 are integrally formed.

[0021] In the present utility model, an arc groove 9 is provided on one side where the connecting block 3 is connected to the inner ring 14, and part of the disk body of the driving disk 13 is located inside the arc groove 9. The multiple arc grooves 9 limit the driving disk 13 so that it can rotate within the limiting space formed by the multiple arc grooves 9.

[0022] In the utility model, the power unit includes a gear ring 8 sleeved on the circumference of the driving disk 13, a gear 4 meshing with the gear ring 8 and a power source driving the gear 4 to rotate are rotatably provided on the connecting block 3. The power source drives the gear 4 to rotate, and the gear 4 meshes with the gear ring 8 to move, thereby controlling the driving disk 13 to rotate. The power source here is a motor, and the control, setting and power supply of the motor are all existing technologies.

[0023] By controlling the rotation of the driving disk 13, the driving disk 13 will cause the transmission rod 1 to change position. Since the position movement of the positioning block 15 is limited by the slide groove, the driving disk 13 will bring the positioning block 15 close to the axis of the inner ring 14 or away from the axis of the inner ring 14 according to the rotation direction. Since the size of the cable clamping space and the size of the cable core clamping space are determined according to the position of the transmission rod 1, it is possible to control the size of the cable clamping space and the size of the cable core clamping space, so that the device can clamp the cable and the cable core through a driving component.

It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
