Description

Technical Field

[0001] The utility model belongs to the technical field of cable stripping, and in particular relates to a cable stripping machine. Background Art

[0002] With the rapid development of social economy, the core carriers of the power system are primary and secondary cables. All protection screens, terminal box circuits and power line connections involve cable stripping.

[0003] After searching, the publication number: CN216981365U discloses a cable stripping machine. In the utility model, by setting a cable placement groove and a stripping cutting knife, the cable is placed in the cable placement groove and the cable pressing and clamping plate is inserted into the through-limiting groove. The cable is pressed by the cable pressing and clamping plate, and then the cable is rotated to cut off the cable sheath, thereby realizing cable stripping. The depth of the stripping cutting knife sliding out of the cutting knife through-groove is adjustable to achieve a fixed depth of cutting the cable sheath, thereby avoiding damage to the cable core and making the cable stripped completely. Although the device can ensure the cutting depth, its cable pressing and clamping plate is against the outside of the insulating sheath of the cable, making it difficult to pull the cable out while cutting, and the operation is laborious.

[0004] Therefore, a cable stripping machine is designed to solve the above problems. Utility Model Content

[0005] To solve the problems raised in the above background technology. The utility model provides a cable stripping machine. When the device is in use, the cable can be placed into the cable placement rack along the inner side of two sets of positioning clamps. To ensure the clamping reliability of cables of different models, the device can automatically start the stepper motor on the top through the control end, and its motor shaft drives the bidirectional screw to rotate. Since the limit block on the inner side of the positioning clamp is always embedded in the slide groove, the positioning clamp can effectively prevent the synchronous rotation with the bidirectional screw, and through the cooperation with the built-in thread groove, the two sets of positioning clamps can approach each other and complete the firm clamping of the cable. The finely ground steel balls on the clamping surface are in rolling contact with the cable, so that the staff can pull the cable out without excessive force when pulling the cable, and the operation is simple.

[0006] While the positioning splint is moving, the support plate on the outside can extend and retract along the inner diameter of the slot opening, thereby maintaining the stability of the positioning splint. To prevent the scraper body from cutting the cable skin, the staff can rotate the threaded handle rod on the outside of the fixed frame. The threaded handle rod gradually penetrates inward and pushes the scraper body inside. The elastic support rod can ensure that the end face of the scraper body is always tightly fitted with the inner side of the threaded handle rod to achieve a pushing effect, so that the tip of the scraper body extends outward and adjusts the incision size, thereby effectively preventing the cable skin from being scratched.

[0008] As a preferred cable stripping machine of the utility model, a stepper motor and a bidirectional screw are also arranged on the top of the cable placement rack, the motor shaft of the stepper motor is fixedly connected to one end of the bidirectional screw through a coupling, and the bidirectional screw is threadedly sleeved on one side of the positioning clamp.

[0009] As a preferred embodiment of the cable stripping machine of the utility model, a thread groove matching the size of the bidirectional screw is formed through the inner side of the positioning clamping plate.

[0010] As a preferred embodiment of the cable stripping machine of the utility model, the positioning clamp and the opposite side of the cable placement rack are also provided with mutually matching sliding grooves and limit blocks.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown:

[0026] A cable stripping machine is disclosed in CN216981365U. The cable can be pressed by a cable pressing plate and then rotated to cut off the cable sheath, thereby achieving cable stripping. The depth of the stripping cutter sliding out of the cutting cutter penetration groove is adjustable, so as to achieve a fixed depth of cutting the cable sheath, thereby avoiding damage to the cable core and ensuring that the cable is completely stripped. Although the device can ensure the cutting depth, its cable pressing plate is pressed against the outside of the insulating sheath of the cable, making it difficult to pull the cable out while cutting, and the operation is laborious. On this basis, a stripping mechanism 1 is added.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown:

[0028] In an optional embodiment: the stripping mechanism 1 includes a cable placement frame 11, a positioning clamp 12, a finely ground steel ball 13, a support plate 14, a fixing frame 15, a threaded handle rod 16 and a scraper body 17. The positioning clamp 12 is slidably connected to the outer side of the cable placement frame 11, and the finely ground steel ball 13 is rotatably connected to the inner side of the positioning clamp 12. The surface of the support plate 14 is fixedly connected to the outer wall surface of the positioning clamp 12. The fixing frame 15 is slidably sleeved on the opposite side of the support plate 14. The threaded handle rod 16 is threadedly connected to the middle part of the fixing frame 15. The inner side of the scraper body 17 abuts against the outer side of the threaded handle rod 16. A stepper motor 2 and a bidirectional screw 3 are also provided on the top of the cable placement frame 11. The motor shaft of the stepper motor 2 is fixedly connected to one end of the bidirectional screw 3 through a coupling, and the bidirectional screw 3 is threadedly sleeved on one side of the positioning clamp 12.

[0029] In this embodiment: the cable can be placed into the cable placement rack 11 along the inner side of the two groups of positioning clamps 12. To ensure the clamping reliability of cables of different types, the device can automatically start the stepper motor 2 on the top through the control end, and its motor shaft drives the bidirectional screw 3 to rotate. Since the limit block 6 on the inner side of the positioning clamp 12 is always embedded in the slide groove 5, the positioning clamp 12 can effectively prevent the synchronous rotation with the bidirectional screw 3, and by cooperating with the built-in thread groove 4, the two groups of positioning clamps 12 can approach each other and complete the secure clamping of the cable. The finely ground steel balls 13 on the clamping surface are in rolling contact with the cable, so that the staff can pull the cable out without excessive force when pulling the cable, and the operation is simple.

[0030] More specifically:

[0031] like Figure 1 , Figure 4 and Figure 5 As shown:

[0032] In an optional embodiment: a threaded groove 4 matching the size of the bidirectional screw 3 is penetrated through the inner side of the positioning clamp 12, and a sliding groove 5 and a limit block 6 matching each other are provided on the opposite side of the positioning clamp 12 and the cable placement frame 11, and an elastic support rod 7 is also provided inside the fixed frame 15, and the two ends of the elastic support rod 7 are respectively fixedly connected to the scraper body 17 and the opposite side surfaces of the fixed frame 15, and notches 8 matching the size of the support plate 14 are also provided on both sides of the fixed frame 15.

[0033] In this embodiment: while the positioning splint 12 is moving, the support plate 14 on the outer side can be extended and retracted back and forth along the opening inner diameter of the slot 8, thereby maintaining the stability of the positioning splint 12. To prevent the scraper body 17 from cutting the cable skin, the staff can rotate the threaded handle rod 16 on the outer side of the fixed frame 15, and the threaded handle rod 16 gradually penetrates inward and pushes the internal scraper body 17. The elastic support rod 7 can ensure that the end face of the scraper body 17 is always tightly fitted with the inner side of the threaded handle rod 16 to achieve a pushing effect, so that the tip of the scraper body 17 extends outward to adjust the incision size, thereby effectively preventing the cable skin from being scratched.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
