Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically, to a cable cutting device. Background Technology

[0002] Control boxes are usually produced in small batches, and the number of cables required during assembly is not large. The length of cables used to assemble different boxes is also different. Purchasing finished cables from outside is time-consuming and costly. Therefore, the electrical assembly workshop will directly cut the required number and length of cable segments from long cables and install the wiring terminals themselves.

[0003] Currently, manual cutting is used, but it has the following drawbacks: long cables are originally in a rolled-up state, and when cutting them, they are bent into a certain arc, which leads to inaccurate cutting lengths and increases the difficulty of manual cutting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention innovatively provides a cable cutting device that replaces manual labor, improves cutting accuracy, allows for adjustable and controllable cutting length, reduces dimensional errors caused by the bending of long cables during the cutting process, increases automation, and saves time and effort.

The reciprocating pushing mechanism is used to drive the pressure block closer to or away from the wire feeding roller. The reciprocating pushing mechanism is slidably connected to the bracket through the sliding mechanism.

[0009] The cutting mechanism is fixed on the bracket and located at the next station after the wire feeding mechanism and the fastening mechanism, and is used to cut the cable.

[0010] Furthermore, the fastening mechanism includes two fastening mechanism bodies and a push rod. Each fastening mechanism body includes a fixed block, a latch, and an elastic element. The fixed block has a first sliding groove and is fixedly connected to the bracket. The groove direction of the first sliding groove is the same as the reciprocating pushing direction of the reciprocating pushing mechanism. The middle part of the latch is rotatably connected to the end of the fixed block away from the first sliding groove. A second sliding groove is provided on the part of the latch near the first sliding groove to the connection point with the fixed block. One end of the elastic element is fixedly connected to the end of the latch near the first sliding groove, and the other end of the elastic element is fixedly connected to the surface of the bracket where the fixed block is located. The elastic extension and contraction direction of the elastic element is the same as the groove direction of the first sliding groove. The two fastening mechanism bodies are distributed at both ends of the push rod. The push rod is inserted into the first and second sliding grooves. The reciprocating pushing mechanism is used to push the push rod to slide in the first and second sliding grooves.

[0011] Furthermore, the end of the reciprocating pushing mechanism is also fixed with a push block for pushing the push rod, and the surface shape of the push block that contacts the push rod matches the shape of the push rod.

[0012] Furthermore, the surface of the pressure block that contacts the cable is an arc-shaped surface, and the roller surface of the wire feeding roller is arc-shaped.

[0013] Furthermore, the surface of the pressure block that contacts the cable is provided with an anti-slip part.

[0014] Furthermore, it also includes a guide plate, which is disposed at the upper station of the wire feeding mechanism. The guide plate is fixedly connected to the bracket, and the surface of the guide plate that contacts the cable is an arc-shaped surface.

[0015] Furthermore, the wire feeding mechanism includes a rotating shaft and a baffle, the rotating shaft being rotatably connected to the bracket, and the baffle being fixed on the end of the rotating shaft away from the bracket.

[0016] Furthermore, it also includes an anti-reverse mechanism, which is fixed on the bracket to prevent the shaft from reversing.

[0017] Furthermore, the cutting mechanism includes a fixed cutting part and a movable cutting part, the fixed cutting part is fixed on the bracket, and the movable cutting part is rotatably connected to the fixed cutting part.

[0018] Furthermore, the sliding mechanism includes a linear guide rail and a slider that matches the linear guide rail, wherein one of the linear guide rail and the slider is fixedly connected to the bracket and the other is fixedly connected to the reciprocating pushing mechanism.

[0031] The cable cutting device provided by the present invention will be explained and described in detail below with reference to the accompanying drawings.

[0032] This embodiment specifically discloses a cable cutting device, such as... Figure 1 and 2 As shown, it includes a bracket 1, a cable feeding mechanism 2, a cable delivery mechanism 3, a fastening mechanism 4, and a cutting mechanism 5. The cable feeding mechanism 2 is rotatably connected to the bracket 1 and is used to fix the coiled cable and rotates as the cable 6 is released; Figure 1 and 2 As shown, the bracket 1 includes a base plate 11, an upright plate 12, and a side plate 13. The upright plate 12 and the side plate 13 are both vertically fixed to the base plate 11, and are also perpendicular to each other. In this embodiment, the wire feeding mechanism 2 is rotatably connected to the upright plate 12. Figure 1-4 As shown, the wire feeding mechanism 2 includes a rotating shaft 21 and a baffle 22. The rotating shaft 21 is rotatably connected to the support 1, and the baffle 22 is fixed on the end of the rotating shaft 21 away from the support 1. The rotating shaft 21 is vertically fixed to the upright plate 12 and rotatably connected to the upright plate 12. Both ends of the rotating shaft 21 protrude from the upright plate 12. The baffle 22 is fixed on the end of the rotating shaft 21 in front of the upright plate 12. The baffle 22 and the side plate 13 are on the same side of the upright plate 12. Figure 1 As shown, the coiled cable is looped on the rotating shaft 21. When the coiled cable rotates to release the cable 6, the rotating shaft 21 rotates accordingly, reducing the resistance of releasing the cable 6. The baffle 22 prevents the coiled cable from slipping off the rotating shaft 21.

[0033] like Figure 5 As shown, the cable cutting device also includes an anti-reverse mechanism 23, which is fixed to the bracket 1 to prevent the rotating shaft 21 from reversing. In this embodiment, the anti-reverse mechanism 23 is fixed to the back of the upright plate 12, on a different side from the baffle 22. The anti-reverse mechanism 23 can be a commonly used mechanism in the art, such as a ratchet mechanism. Figure 5As shown, the anti-reverse mechanism 23 includes a ratchet 231, a pawl 232, a spring 233, and a fixing plate 234. The ratchet 231 is coaxially connected to the end of the rotating shaft 21 located on the back of the upright plate 12. The pawl of the pawl 232 is engaged with the ratchet 231, and the end of the pawl 232 away from the pawl is rotatably connected to the upright plate 12. The fixing plate 234 is fixed on the upright plate 12. A spring 233 is fixed between the fixing plate 234 and the pawl 232. The connection between the spring 233 and the pawl 232 is located in the middle of the pawl 232. The ratchet 231, the pawl 232, and the spring 233 cooperate with each other to prevent the rotating shaft 21 from reversing.

[0034] Furthermore, such as Figure 2 and 5 As shown, the anti-reverse mechanism 23 is covered with a protective cover 24, which is fixedly connected to the upright plate 12.

[0035] like Figure 1-4 As shown, the wire feeding mechanism 3 includes a sliding mechanism 31, a reciprocating pushing mechanism 32, and a clamping mechanism 33. The clamping mechanism 33 includes a wire feeding roller 331 and a pressure block 332. One or more wire feeding rollers 331 are fixed on the bracket 1 and rotatably connected to the bracket 1. The multiple wire feeding rollers 331 are arranged along a direction perpendicular to the roller axis of the wire feeding rollers 331. The pressure block 332 is fixedly connected to the reciprocating pushing mechanism 32. The pressure block 332 is used to cooperate with the wire feeding roller 331 to clamp the cable 6. The reciprocating pushing mechanism 32 is used to drive the pressure block 332 closer to or away from the wire feeding roller 331. The pressure block 332 is close to the wire feeding roller 331 by a certain distance. The cable 6 can be clamped between the pressure block 332 and the wire feeding roller 331. Releasing the pressure block 332 away from the wire feeding roller 331 releases the cable 6. The reciprocating pushing mechanism 32 is slidably connected to the bracket via the sliding mechanism 31. The sliding mechanism 31 drives the reciprocating pushing mechanism 32 and the pressure block 332 to slide along a direction perpendicular to the roller axis of the wire feeding roller 331, i.e., along the direction in which the wire feeding roller 331 feeds the cable. After the pressure block 332 and the wire feeding roller 331 clamp the cable 6, the sliding mechanism 31 drives the pressure block 332 to slide along the direction in which the wire feeding roller 331 feeds the cable, thus achieving wire feeding and adjusting the length of the cut cable 6. The length of the cut cable 6 is related to the sliding length of the sliding mechanism 31, thereby allowing for more precise control of the cut cable length.

[0036] The sliding mechanism 31 includes a linear guide rail 311 and a slider 312 that matches the linear guide rail 311. One of the linear guide rail 311 and the slider 312 is fixedly connected to the bracket 1, and the other is fixedly connected to the reciprocating pushing mechanism 32. In this embodiment, as shown... Figure 1-4As shown, the sliding mechanism 31 is fixed to the base plate 11, and the sliding direction of the sliding mechanism 31 is perpendicular to the vertical plate 12. The wire feeding roller 331 is fixed to the side plate 13, and multiple wire feeding rollers 331 are arranged in a direction perpendicular to the vertical plate 12. The linear guide rail 311 is fixed to the base plate 11, and the slider 312 is located above the linear guide rail 311 and engaged with the linear guide rail 311. The reciprocating pushing mechanism 32 is fixed to the top of the slider 312 and slides with the slider 312. The reciprocating pushing mechanism 32 can be a cylinder, a hydraulic cylinder, or an electric telescopic rod, and the direction of the reciprocating motion of the movable end of the reciprocating pushing mechanism 32 is perpendicular to the side plate 13. Figure 1-3 As shown, there are two pressure blocks 332 and multiple wire feeding rollers 331. The two pressure blocks 332 are spaced apart and are directly opposite the rows formed by the wire feeding rollers 331. The two pressure blocks 332 are fixedly connected to the movable end of the reciprocating push mechanism 32 via a U-shaped connecting rod. After the two pressure blocks 332 and the wire feeding rollers 331 clamp the cable 6, the sliding mechanism 31 slides away from the wire feeding mechanism 2, pulling the cable 6 and releasing it from the coiled cable. The design of the two pressure blocks 332 ensures the stability and reliability of the wire feeding process and prevents the cable 6 from slipping.

[0037] In this embodiment, as Figure 4 and 6 As shown, the surface of the pressure block 332 that contacts the cable 6 is an arc-shaped surface, and the roller surface of the wire feeding roller is also arc-shaped, which ensures the stability of clamping the cable 6 and prevents the cable 6 from slipping off.

[0038] Furthermore, such as Figure 6 As shown, the surface of the pressure block 332 that contacts the cable 6 is provided with an anti-slip part 333. The anti-slip part 333 can be knurled or a rubber pad to increase the frictional resistance of the pressure block surface.

[0039] The slider 312 of the sliding mechanism 31 can be driven manually or by a sliding drive device along the linear guide rail 311. The sliding drive device can be a motor, cylinder, hydraulic cylinder or electric telescopic rod. The motor is connected to the slider 312 through a lead screw mechanism.

[0040] In this embodiment, as Figure 1-3 As shown, the cable cutting device also includes a guide plate 8, which is positioned above the cable feeding mechanism 3. The guide plate 8 is fixedly connected to the bracket 1, and the surface of the guide plate 8 that contacts the cable 6 is an arc-shaped surface. The guide plate 8 is fixed to the side plate 13, with the arc-shaped surface of the guide plate 8 facing the side plate 13. The space between the guide plate 8 and the side plate 13 forms for the cable 6 to pass through, straightening the bent cable 6, reducing the curvature of the cable, and providing guidance to facilitate the smooth feeding of the cable by the subsequent cable feeding mechanism 3. In this embodiment, the guide plate 8 is bent at a right angle, as shown... Figure 1As shown, this allows for a smooth transition of cable 6 from the vertical plate 12 to the side plate 13, ensuring that cable 6 is smoothly introduced into the area between the pressure block 332 and the wire feeding roller 331 under the restriction of the guide plate 8.

[0041] like Figure 1-4 As shown, the fastening mechanism 4 is fixed on the bracket 1. The reciprocating pushing mechanism 32 is also used to push the fastening mechanism 4 to engage with the bracket 1 to fasten the cable 6 when the pressure block 332 and the wire feeding roller 331 release the cable 6, and to release the cable 6 when the pressure block 332 and the wire feeding roller 331 clamp the cable 6. The cutting mechanism 5 is fixed on the bracket 1 and located at the next station after the wire feeding mechanism 3 and the fastening mechanism 4. It is used to cut the cable 6. After the wire feeding mechanism 3 conveys a certain length of cable 6, the sliding mechanism 31 stops sliding. The length of the cable 6 to be cut is determined. At the same time as the pressure block 332 and the wire feeding roller 331 release the cable 6, the fastening mechanism 4 fastens the cable 6 between the fastening mechanism 4 and the bracket 1, fixing the cable 6 so that the cutting mechanism 5 can cut it.

[0042] As shown in 1-4 and 7, the fastening mechanism 4 includes two fastening mechanism bodies 41 and a push rod 42, as follows: Figure 8As shown, the fastening mechanism body 41 includes a fixing block 411, a latch 412, and an elastic member 413. The fixing block 411 is provided with a first sliding groove 414 and is fixedly connected to the bracket 1. The groove direction of the first sliding groove 414 is the same as the reciprocating pushing direction of the reciprocating pushing mechanism 32. The fixing block 411 is fixed to the side plate 13, and the groove direction of the first sliding groove 414 is perpendicular to the side plate 13. The middle part of the latch 412 is rotatably connected to the end of the fixing block 411 away from the first sliding groove 414. A second sliding groove 415 is provided on the part of the latch 412 from the end near the first sliding groove 414 to the connection point with the fixing block 411. One end of the elastic member 413 is fixedly connected to the end of the latch 412 near the first sliding groove 414, and the other end of the elastic member 413 is fixedly connected to the surface of the bracket 1 where the fixing block 411 is located. The elastic member 413... The direction of the extension and retraction is the same as the groove direction of the first slide groove 414. The two fastening mechanism bodies 41 are distributed at both ends of the push rod 42. The push rod 42 is inserted into the first slide groove 414 and the second slide groove 415. The reciprocating pushing mechanism 32 is used to push the push rod 42 to slide in the first slide groove 414 and the second slide groove 415. When the reciprocating pushing mechanism 32 pushes the push rod towards the fixed surface (i.e., the side plate) of the fixed block on the bracket, the pawl compresses the elastic element. The end of the pawl away from the first slide groove slides away from the fixed surface (i.e., the side plate) of the fixed block on the bracket. When the movable end of the reciprocating pushing mechanism 32 moves in the opposite direction, under the restoring elastic force of the elastic element, the push rod slides away from the fixed surface (i.e., the side plate) of the fixed block on the bracket, and the end of the pawl away from the first slide groove moves towards the fixed surface of the fixed block on the bracket, cooperating with the bracket to fasten the cable. In this embodiment, the latch 412 includes a claw portion and a handle portion. The connection between the claw portion and the handle portion is rotatably connected to the end of the fixing block 411 away from the first slide groove 414 via a rotating shaft. The second slide groove 415 is formed on the handle portion. The first slide groove is along the length direction of the handle portion. The push rod 42 passes through all the first slide grooves 414 and the second slide grooves 415. The two latching mechanism bodies 41 are located on both sides of the multiple wire feeding rollers 331 arranged in a row. The push rod 42 is located below the wire feeding rollers 331. The movement process of the reciprocating pushing mechanism 32 does not interfere with the latching mechanism 4. The elastic element 413 is a spring. The elastic extension direction of the elastic element 413 is perpendicular to the side plate 13. When the elastic element 413 is in its natural state, the push rod 42 is located at the end of the first slide groove 414 away from the side plate 13, and the latch 412 fastens the cable 6 between the latch and the side plate 13; when the reciprocating push mechanism 32 pushes the push rod 42 toward the side plate 13, the elastic element 413 is compressed, and the latch 412 moves away from the side plate 13, releasing the cable 6.

[0043] In this embodiment, as Figure 1-4As shown in Figure 7, a push block 7 for pushing the push rod 42 is also fixed to the end of the reciprocating pushing mechanism 32. The surface shape of the push block 7 in contact with the push rod 42 matches the shape of the push rod 42. The push block 7 is located below the pressure block 332 and is fixedly connected to the U-shaped connecting rod via an L-shaped connecting rod, so that the reciprocating pushing mechanism 32 can simultaneously drive the pressure block 332 and the push block 7 to move. In this embodiment, the push rod 42 is a cylindrical rod, so the contact surface between the push block 7 and the push rod 42 is set as an arc surface to avoid misalignment between the push rod 42 and the push block 7, and to ensure the accuracy of the fastening mechanism body 41 in fastening and releasing the cable 6.

[0044] like Figure 1-4 As shown, the cutting mechanism 5 includes a fixed cutting part 51 and a movable cutting part 52. The fixed cutting part 51 is fixed on the bracket 1, and the movable cutting part 52 is rotatably connected to the fixed cutting part 51. The movable cutting part 52 and the fixed cutting part 51 work together to complete the cutting action. Both the fixed cutting part 51 and the movable cutting part 52 are equipped with blades. The rotatable connection between the movable cutting part 52 and the fixed cutting part 51 can be driven manually or by a rotation drive device, which can be a motor. After the wire feeding mechanism 3 feeds the cable 6 of the required length, the pressure block 332 and the wire feeding roller 331 release the cable 6, while the fastening mechanism 4 fastens the cable 6, and the cutting mechanism 5 cuts the cable 6.

[0045] The anti-reverse mechanism 23 prevents the shaft 21 from reversing. Even if the release action of the latch 412 and the clamping action of the clamping mechanism 33 on the cable 6 are not completely synchronized, it can ensure that the cable 6 that has been pulled out will not retract.

[0046] Furthermore, the cable cutting device in this embodiment may also include a controller, which is electrically connected to the sliding drive device of the sliding mechanism 31, the reciprocating push mechanism 32 and the rotation drive device of the cutting mechanism 5. The controller controls each step of the action to achieve automated cable cutting.

[0047] The method by which the cable cutting device in this embodiment cuts cable 6 is as follows:

[0048] Cable 6 is coiled and hung on shaft 21. When cable 6 is pulled, shaft 21 rotates accordingly. The end of cable 6 passes through guide plate 8. When slider 312 on linear guide rail 311 drives reciprocating push mechanism 32 to move towards vertical plate 12, pressure block 332 approaches guide plate 8. Reciprocating push mechanism 32 moves and pushes pressure block 332 towards side plate 13, clamping cable 6 together with wire feeding roller 331. At the same time, push block 7 pushes push rod 42 to release cable 6 from pawl 412. When linear guide rail 311... The reverse movement of slider 312 on plate 1 causes pressure block 332 to move cable 6 towards cutting mechanism 5. During this process, wire feed roller 331 rotates with cable 6 to promote its forward movement. Slider 312 stops at the specified position, and reciprocating push mechanism 32 moves away from side plate 13. Pressure block 332 releases cable 6, and push block 7 releases push rod 42. Claws 412 move towards side plate 13 to re-clamp cable 6, and the portion of cable 6 entering cutting mechanism 5 is cut off. Cable 6 extends into the upper end of fixed cutting part 51, and movable cutting part 52 moves downward to cut cable 6. During the cutting process, clamping mechanism 4 clamps cable 6 onto fixed cutting part 51, preventing cable 6 from shifting during cutting.

[0049] The cutting length of cable 6 depends on the running length of slider 312 on linear guide rail 311, which improves the cutting accuracy. Moreover, the cutting length is adjustable and controllable. The clamping and feeding process of pressure block 332 and wire feeding roller 331 reduces the curvature of the bent cable 6, thereby reducing the dimensional error caused by the bending of the long cable 6 itself.
