Description

Technical Field

[0001] The invention relates to the technical field of cable repair equipment, in particular to a positioning mechanism and a cable cutting device. Background Art

[0002] Cables are the transmission channels of electric current. When cables are damaged, it will affect the transmission of electricity and cause power outages of varying scopes. Moreover, sudden power outages will have a great impact on life or industrial production, causing immeasurable losses. During the use of cables, due to the influence of the environment or other factors, the cable sheath may wear or crack, causing the inner core of the cable to leak out, leakage or short circuit. However, when the cable sheath is damaged or cracked, it is often only a single section. Completely replacing the entire cable will increase the cost. Therefore, when the cable sheath is damaged, the electrician will first cut off the damaged cable sheath and then repair it. However, during actual cutting, the cable will shake due to the influence of the cutting force, affecting the normal cutting work. Therefore, we propose a positioning mechanism and a cable cutting device. Summary of the invention

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1, reference Figure 1 to Figure 3, is the first embodiment of the present invention, which provides a positioning mechanism, including a placement component 100, including a support frame 101, and a support block 102 arranged at the highest end of the support frame 101, and a rotating drum 103 for placing damaged cables is arranged on the support block 102; when this embodiment is used, one end of the damaged part of the cable is first placed in the rotating drum 103, and after waiting for fixation, the damaged surface is directly cut for subsequent repair. The positioning component 200 includes a cutting block 201 installed on the rotating drum 103, and the end of the cutting block 201 close to the rotating drum 103 penetrates the outer wall of the rotating drum 103, slides and extends to the inside of the rotating drum 103 and is installed with a cutting tool 202 for cutting damaged cables. The setting of the cutting tool 202 is to cut the damaged protective layer on the surface of the damaged cable. When in use, the cutting block 201 can be controlled to make one end of the cutting tool 202 penetrate into the cable protective layer for cutting, thereby avoiding the situation where the damaged protective layer outside the cable is not cut sufficiently.

[0026] Furthermore, an auxiliary block 203 is provided on the side of the rotating drum 103 opposite to the cutting block 201, and the end of the auxiliary block 203 close to the rotating drum 103 slides through the inner cavity of the rotating drum 103 to squeeze the damaged cable. After the damaged cable is inserted into the rotating drum 103, the cutting block 201 and the auxiliary block 203 are controlled to move synchronously and approach the cable. Finally, the cutting tool 202 and the auxiliary block 203 clamp the cable to achieve the effect of fixing the cable, thereby ensuring that the cable is not easily shaken under the action of external force during the cutting process. The situation of cutting position deviation is avoided, the cutting quality of the damaged protective layer of the cable is improved, and the subsequent cable repair is convenient.

[0027] Furthermore, the cutting tool 202 and the cutting block 201 are detachably installed. In this embodiment, the detachable connection between the cutting tool 202 and the cutting block 201 can adjust the installation position of the cutting tool 202 on the cutting block 201, thereby controlling the angle at which the cutting tool 202 penetrates into the cable, so that the staff can adjust the cutting angle of the damaged cable according to the actual situation, because cutting at different angles can change the mechanical force applied to the cable, which is very important for fragile cables or cables that need to maintain their shape, and can avoid deformation or damage to the inside of the cable caused by mechanical force, thereby increasing the protection of the cable and reducing the subsequent cable repair costs.

[0028] When in use, the cutting tool 202 and the auxiliary block 203 clamp the cable, thereby achieving a fixing effect on the cable, ensuring that the cable is not easily displaced in the cutting position due to external force during the cutting process, which is beneficial to the subsequent repair of the cable. In addition, the adjustment of the position of the cutting tool 202 allows the staff to adjust the cutting angle of the damaged cable according to actual conditions, change the mechanical force applied to the cable during cutting, avoid internal deformation or damage of the cable due to mechanical force, and reduce the subsequent repair cost of the cable.

[0029] Example 2, reference Figure 1 to Figure 3 , which is the second embodiment of the present invention. Different from the previous embodiment, it also includes a driving assembly 300 for controlling the movement of the cutting block 201 and the auxiliary block 203 provided on the rotating drum 103, and the driving assembly 300 includes a driving motor 301 fixedly installed on the rotating drum 103, and a driving gear 303 is rotatably installed on the rotating drum 103. A transmission member 302 for power transmission is provided between the driving motor 301 and the driving gear 303. The driving motor 301 is a dual-axis motor, and the ends of the cutting block 201 and the auxiliary block 203 away from the rotating drum 103 are respectively fixedly installed with driving racks 304 meshing with the driving gear 303. In this embodiment, the driving motor 301 is started to cooperate with the transmission member 302 to drive the driving gear 303 to rotate. Because the driving gear 303 is meshed with the driving rack 304, when the driving gear 303 rotates, it will drive the driving rack 304 meshed with it to move synchronously. In addition, because the driving motor 301 is a dual-axis motor, when the driving motor 301 is running, the cutting block 201 and the auxiliary block 203 will move synchronously driven by their respective driving racks 304 until the purpose of fixing and clamping the cable is completed.

[0030] Furthermore, the drum 103 is rotatably connected to the support block 102, and a rotating assembly 400 for controlling the rotation of the drum 103 is provided on the support frame 101, the rotating assembly 400 includes a mounting connecting rod 401 fixedly mounted on the support frame 101, and a rotating gear 402 is rotatably mounted on one end of the mounting connecting rod 401 away from the support frame 101, and a rotating gear ring 403 meshing with the rotating gear 402 is wound around the outside of the drum 103, and the rotating gear ring 403 and the drum 103 are coaxially arranged. During the cable fixing process, the cutting tool 202 arranged on the cutting block 201 will penetrate into the damaged cable. At this time, the rotating drum 103 can be driven to rotate through the rotating component 400, so that the various components arranged on the rotating drum 103 will make a circular motion with the axis of the rotating drum 103 as the center, so as to achieve the circular cutting effect of the cutting tool 202 on the damaged cable belt and complete the cable cutting operation. During specific operation, the rotating gear 402 can be pushed to rotate first, and the engagement between the rotating gear 402 and the rotating gear ring 403 can be used to drive the rotating drum 103 fixed to the rotating gear ring 403 to rotate.

[0031] Furthermore, an auxiliary wheel 204 is rotatably mounted on one end of the auxiliary block 203 close to the damaged cable. Because the positioning assembly 200 fixes the cable by increasing the friction between each other, when the drum 103 rotates, the auxiliary block 203 that is squeezing the cable will affect the rotation of the drum 103. In this embodiment, the auxiliary wheel 204 is arranged at the contact end of the auxiliary block 203 and the cable, so that the friction between the cable and the auxiliary block 203 is converted from sliding friction to rolling friction, which greatly reduces the friction between the cable and the auxiliary block 203 and reduces the impact on the rotation of the drum 103.

[0032] When in use, the driving assembly 300 is set so that the cutting block 201 and the auxiliary block 203 move synchronously until the purpose of fixing and clamping the cable is achieved. In addition, the setting of the auxiliary rotating wheel 204 converts the friction between the cable and the auxiliary block 203 from sliding friction to rolling friction, which greatly reduces the friction between the cable and the auxiliary block 203 and reduces the impact on the rotation of the drum 103.

[0033] Example 3, reference Figure 4 , which is the third embodiment of the present invention, further provides a cable cutting device. It includes a guide assembly 500, including a guide groove 501 provided on the support block 102, and a guide ring 502 is fixedly wound around the outside of the rotating drum 103 and slidably connected to the guide groove 501. The setting of the guide groove 501 and the guide ring 502 provides a guiding effect for the rotation of the rotating drum 103, ensuring that the rotating drum 103 maintains the correct direction and position during the rotation process, and does not deviate.

[0034] Furthermore, the edges of the guide groove 501 and the guide ring 502 are both configured as smooth curved surfaces. The configuration of the smooth curved surface reduces the friction loss between the guide groove 501 and the guide ring 502, which helps to improve the efficiency and life of the guide assembly 500.

[0035] When in use, the guide groove 501 and the guide ring 502 provide a guiding effect for the rotation of the rotating drum 103, ensuring that the rotating drum 103 maintains the correct direction and position during the rotation process and does not deviate, thereby ensuring the stability of the rotating drum 103 during the rotation process.
