Technical Field

[0001] The invention relates to the technical field of cable peeling devices, in particular to a high-precision cable peeling device. Background Art

[0002] Wires are widely used in industry, such as industrial electrical equipment, electronic products, etc. Currently, many wires need to be stripped of the outer sheath at the ends of the wires before wiring to expose the conductors at both ends of the wires.

The fixing plate 703 is arranged on the front end surface of the driving disk 7012, and the fixing plate 703 is fixedly connected to the supporting outer tube 6. The driving disk 7012 and the fixing plate 703 are both provided with through holes connected to the inside of the connecting tube 7011 at the center, that is, the fixing plate 703 and the driving disk 7012 can rotate relative to each other. One end of the rotating head 2 is provided with a groove that matches the mounting groove and the fixing plate 703, and the rotating head 2, the fixing plate 703 and the mounting groove can rotate relative to each other. , a plurality of clamping members 704 are slidably arranged on the front end surface of the fixed plate 703 through the second slide groove 7031.

Since the fixing plate 703 is fixed on the supporting outer tube 6, the second connecting member 705 is driven to slide inside the arc groove 7013, and then the second connecting members 705 are synchronously driven to slide inside the second slide groove 7031, so as to clamp or loosen the cable.

[0035] Reference Figure 6-7The second rotation driving module 702 includes a rotation connecting member 7025 fixedly sleeved on the outer peripheral wall of the connecting tube 7011, a driven wheel 7021 coaxially sleeved on the outside of the rotation connecting member 7025, a second driving wheel 7023 installed on one side of the driven wheel 7021 through a support plate, a second connecting belt 7022 connecting the second driving wheel 7023 and the driven wheel 7021, and a second driving motor 7024 for driving the second driving wheel 7023 to rotate. The rotation connecting member 7025 includes a mounting ring fixedly sleeved on the connecting tube 7011 and a plurality of limit blocks arranged at equal intervals on the outer wall of the mounting ring. A through hole matching the mounting ring is penetrated at the center of the driven wheel 7021, and the inner wall of the through hole is provided with a plurality of limit blocks at equal intervals. A plurality of connection grooves 7026 corresponding to the limit blocks are arranged, and the limit blocks are connected to one side of the connection groove 7026 through an elastic support member, and the elastic support member can be a spring (not shown in the figure). When working, the second driving motor 7024 drives the second driving wheel 7023 to rotate, and the second driving wheel 7023 drives the driven wheel 7021 to rotate through the second connecting belt 7022. The driven wheel 7021 is elastically connected to the rotating connecting member 7025 through the elastic support member, and the driving member 701 is driven to rotate through the rotating connecting member 7025 to adjust the spacing of each clamping member 704.

[0036] Reference Figure 5 , an inner support tube 8 for supporting the cable is arranged inside the outer support tube 6, and the inner support tube 8 is a hollow tubular structure with two ends penetrated, and the inner support tube 8 is specifically inserted into the connecting tube 7011 to prevent the cable from rotating when the connecting tube 7011 rotates, and a mounting frame 9 is arranged at one end of the outer support tube 6 away from the rotating head 2, and a through hole is penetrated on the mounting frame 9 to accommodate the inner support tube 8 passing through, and the inner support tube 8 and the mounting frame 9 are fixedly connected by fixing bolts 10, so that different inner support tubes 8 can be replaced according to cables of different sizes;

[0037] Reference Figure 1The front end of the rotating head 2 is also provided with an outer clamping module 4 for clamping the cable. The outer clamping module 4 includes two upper and lower mirror-symmetrical clamping jaws and a driving module for synchronously adjusting the two clamping distances. The driving module includes a screw and a pulley mechanism for driving the screw to rotate. The threads at both ends of the screw are opposite. The two clamping jaws are connected to the screw thread through a slider. When the pulley mechanism drives the screw to rotate, the two clamping jaws are driven to move toward the middle or open to both ends at the same time. The clamping jaws are a V-shaped structure, which can clamp and fix cables of different diameters. During rotary cutting, one end of the cable is inserted into the inner clamping module 7 for clamping, and the other end is clamped by the outer clamping module 4. The cutter module 3 is located between the outer clamping module 4 and the inner clamping module 7, so that the cable is always kept horizontal. During rotary cutting, the cable sags to prevent the rotary cutting center from being offset from the cable center, resulting in a deeper cutting depth in some places on the cable skin and a shallower cutting depth in some places. This not only affects the later peeling, but also may cause wear of the inner core when the cutting depth is too deep.

[0038] Working principle: first, insert the cable from the rear end of the support inner tube 8, one end is clamped by the outer clamping module 4, and the other end of the cable is located inside the support inner tube 8. The second rotation drive module 702 drives the driving member 701 to rotate, so that the second connecting member 705 rotates inside the arc groove 7013. Since the fixing plates 703 are fixed differently, each clamping member 704 is driven to move synchronously along the second slide groove 7031 toward the center of the peeling, and then the cable is clamped. Then, the linear drive module 305 pushes the driving plate 304 to slide back and forth along the axial direction of the support outer tube 6. The linear drive module 305 drives the driving block 303 to slide back and forth along the axial direction of the support outer tube 6. The connecting block on the slider 302 slides inside the guide inclined groove 3031, thereby adjusting the spacing between the two cutters 301. The first rotation drive module 5 drives the rotating head 2 and the cutter module 3 to rotate synchronously, and the cable is peeled to cut the cable sheath, which is convenient for peeling off the sheath later.
