Description

Technical Field

[0001] This invention relates to the field of new energy vehicle wiring harness production technology, specifically to a multi-specification cable shielding mesh cutting device. Background Technology

[0002] When cutting cables with shielded mesh, radial cutting is generally not used because the metal mesh is difficult to cut and is prone to tangling or deformation during the cutting process. Therefore, axial cutting is more commonly used: The first step in shielded mesh cutting is to use cutting equipment to remove the outer insulation layer of the cable to be cut, exposing the shielded mesh. A tool is used to open the exposed front end of the shielded mesh. Then, a tubular blade is inserted between the shielded mesh and the inner layer and moved towards the blade base until the blade head contacts the base. The shielded mesh between the base and the blade head is cut by compression. This axial cutting method minimizes damage to the inner layer. Currently, most devices use a single-specification structure, meaning one device can only cut shielded mesh for one specification of cable. To accommodate multiple specifications, different specifications of tubular blades are used, affecting work efficiency. Summary of the Invention

[0003] To address the above problems, the purpose of this invention is to provide a multi-specification cable shielding mesh cutting device that can adapt to multi-specification cable cutting operations.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 As shown in Figure 7, this device mainly presses down the shielding mesh 11 of the cable 10, causing the shielding mesh segment to be cut to be raised from the cable core wire 12 in an flared shape for cutting. Then, the shielding mesh is flipped over from the inner root of the uncut shielding mesh to a state perpendicular to the outer circumference of the cable core wire. Furthermore, the device can select the appropriate flipping component according to the outer diameter specification of the cable, enhancing its applicability.

[0038] The multi-specification cable shielding mesh cutting device of this application includes a base 13 and a pressing mechanism 14. The base 13 is arranged horizontally, forming a horizontal support surface above the base 13. The pressing mechanism 14 is located on one side above the base 13. The pressing mechanism 14 presses the cable shielding mesh, causing the shielding mesh to be in a raised state, forming an annular insertion space between the outer circumference of the cable core and the inner side of the raised shielding mesh. Specifically, in order to save space occupied by the device, a pair of supports 15 are fixedly installed on the base 13 vertically. Movable brackets are slidably mounted on the outer side of the pair of supports 15 in the horizontal direction. The movable brackets are mounted on the outer side of the supports 15 through slider rails and slide along the side of the supports 15. The movable brackets include two support frames 16 and two movable frames 17 located on both sides below the pressing mechanism 14. The upper end of the support frame 16 extends to accommodate the pressing mechanism 14. The movable frame 17 is mounted on the support frame 16 through slider rails. On the outside of 5, the two movable frames 17 are fixedly connected by a connecting frame 18; a support drive mechanism is provided on the base 13 to drive the pair of movable frames to reciprocate on the base 13; the support drive mechanism includes a pair of drive seats 19 mounted on the base 13, a first drive screw 20 is rotatably mounted between the pair of drive seats 19, and a first motor 21 mounted on the base 13 at the tail end of the drive screw 20. The shaft of the first motor 21 is connected to the first drive screw 20 through a coupling for transmission. A first threaded drive block 22 is mounted on the first drive screw 20. The first threaded drive block 22 is connected to the connecting frame 18. When working, the first motor rotates, and through the first drive screw 20, it drives the first threaded drive block to reciprocate on the first drive screw, so that through the transmission of the connecting frame 18, the movable frame 17 can be driven to reciprocate on the side of the support 15, which can also drive the pressing mechanism 14 above the support frame 16 to reciprocate. By moving the tamping mechanism 14, the tamping mechanism 14 moves towards the end of the cable, while the cable does not need to move, only to be clamped and stabilized. The movement of the tamping mechanism 14 can perform multiple tamping actions on the cable shielding mesh as needed.

[0039] The stamping mechanism 14 in this application can be implemented using the structure of our earlier application, which will not be elaborated here.

[0040] A cutter holder 23 is provided on the base 13 inside the pressing mechanism 14. The cutter holder 23 has a cable hole arranged horizontally for the cable to pass through. The shielding end of the pressed cable extends from one side of the cutter holder 23 through the cable hole to the other side of the cutter holder 23. A cutter disc 24 is detachably installed in the cable hole of the cutter holder 23. The cutter disc 24 has a tapered guide port 25 arranged from the outside of the cutter holder 23 toward the inside of the cutter holder 23 to guide the passage of the cable.

[0041] This application also includes a cutting assembly disposed on the base 13 on one side of the cutter holder 23 and cooperating with the cutter disc to cut the raised cable shielding mesh; the cutting assembly includes a horizontally arranged cylindrical inner tube 26, a middle tube 27, and an outer tube cutter 28; the inner tube 26, the middle tube 27, and the outer tube cutter 28 are arranged with a coaxial centerline, the height of the centerline of the inner tube 26 is consistent with the height of the centerline of the cable hole, and the two centerlines are arranged coaxially to ensure the accuracy of the fit between the cable and the inner tube 26, the middle tube 27, and the outer tube cutter 28.

[0042] The inner tube 26 is located inside the intermediate tube 27, and the inner tube 26 extends and retracts within the intermediate tube 27. Only a gap is maintained between the outer circumferential surface of the inner tube 26 and the inner circumferential surface of the intermediate tube 27 to allow the inner tube 26 to extend and retract. The intermediate tube 27 is located inside the outer tube cutter 28, and the intermediate tube 27 extends and retracts within the outer tube cutter 28. Similarly, only a gap is maintained between the outer circumferential surface of the intermediate tube 27 and the inner circumferential surface of the outer tube cutter 28 to allow the intermediate tube 27 to extend and retract.

[0043] Furthermore, this application also includes an inner tube drive mechanism that drives the inner tube 26 to extend or retract within the intermediate tube 27; an intermediate tube drive mechanism that drives the intermediate tube 27 toward or away from the tool holder 23; and a linkage drive mechanism that links the inner tube 26 and the outer tube tool 28. Under the action of the linkage drive mechanism, the inner tube 26 and the outer tube tool 28 relative to the intermediate tube 27 perform the following actions: the inner tube 26 retracts relative to the intermediate tube 27, and the outer tube tool 28 extends relative to the intermediate tube 27; or the inner tube 26 extends relative to the intermediate tube 27, and the outer tube tool 28 retracts relative to the intermediate tube 27. The inner tube drive mechanism can drive the inner tube 26 to extend or retract in the horizontal direction, guided by the inner circumferential surface of the intermediate tube 27; while the linkage drive mechanism can switch the extension and retraction of the inner tube 26 and the outer tube tool 28.

[0044] In this application, a movable platform 29 is slidably arranged on the top of a pair of supports 15 in the horizontal direction. The movable platform 29 and the movable bracket reciprocate horizontally above the base 13. The top of the pair of supports 15 is slidably arranged with the bottom of the movable platform 29 through a slide rail slider. The pair of supports 15 extend downward to the accommodating space 30 below the base 13. By arranging a pair of supports 15, the pressing mechanism 14 is slidably arranged on the outside of the pair of supports 15 through the movable bracket, and the movement of the movable platform 29 is on top of the pair of supports 15, which makes the device more compact and reduces the space occupied.

[0045] The inner tube drive mechanism, the intermediate tube drive mechanism, and the linkage drive mechanism are arranged above the movable platform 29. Below the movable platform 29, there is a platform drive mechanism that drives the movable platform 29 to reciprocate on top of a pair of supports. The platform drive mechanism includes a second motor 31, a second drive screw 32, two second drive seats 33, and a second threaded drive block 34 located between the pair of supports. A hollowed-out internal support platform 35 is fixedly arranged horizontally between the pair of supports to reduce the weight of the internal support platform 35. The second motor 31 and the two second drive seats 33 are fixedly mounted on the internal support platform 35. The second drive screw 32 is rotatably mounted on the two second drive seats 33. The second motor 31 and the second drive screw 32 form a transmission connection. The second threaded drive block 34 is threadedly mounted on the second drive screw 32. The second threaded drive block 34 is connected to the lower part of the movable platform 29. Through the operation of the second motor 31, the second drive screw 32 is driven to rotate, and the second threaded drive block 34 moves horizontally, thereby driving the movable platform 29 to reciprocate horizontally. The platform drive mechanism is arranged between a pair of supports, which also reduces the space occupied by the device.

[0046] A first guide seat 36 and a second guide seat 37 are fixedly arranged at intervals above the movable platform 29, and four guide rods 38 are slidably arranged on the first guide seat 36 and the second guide seat 37 in the horizontal direction. That is, guide holes are opened on the two guide seats, and the guide rods 38 pass through the guide holes, and the guide holes guide the movement of the guide rods 38. The first guide seat 36 is close to the tool holder 23. One end of the guide rod 38 passes through the first guide seat 36 and is fixed to the tool holder 23 on the outside of the first guide seat 36. The other end of the guide rod 38 passes through the second guide seat 37 and is fixed to the outside of the second guide seat 37. This end is connected to the drive plate 39. A tool holder drive mechanism is provided on the movable platform 29, which drives the guide rods 38 to drive the tool holder 23 to reciprocate in the horizontal direction by driving the drive plate 39. The tool holder drive mechanism includes a third motor 40, a third drive seat 41, a third drive screw 42, and a third threaded drive block 43. The third motor 40 and the third drive seat 41 are mounted on the movable platform 29. The third drive screw 42 is rotatably mounted on the third drive seat 41. The third threaded drive block 43 is threadedly mounted on the third drive screw 42 and is connected to the drive plate 39. When the third motor 40 is working, it drives the third threaded drive block 43 and the drive plate 39 to move horizontally through the third drive screw 42. At the same time, it drives the tool holder to move horizontally outside the first guide seat 36 through the guide rod 38. This allows the tool holder to move towards the cable end so that the cable passes through the cable hole from one side of the tool holder to the other side.

[0047] In this application, the linkage drive mechanism includes an outer tube knife moving block 44, an inner tube moving block 45, a linkage frame 46, and a linkage driver 47, all located above a movable platform 29 between a first guide seat 36 and a second guide seat 37. The outer tube knife moving block 44 and the inner tube moving block 45 are slidably mounted above the movable platform 29 via sliders and slide rails. The tail end of the outer tube knife is mounted on the outer tube knife moving block 44. A U-shaped groove 48 is provided in the middle of the outer tube knife moving block 44, and the tail end of the outer tube knife is a step-like section inserted into the U-shaped groove 48, thus forming an assembly between the tail end of the outer tube knife and the outer tube knife moving block 44. The tail end of the inner tube 26 is mounted on the inner tube moving block 45. The middle part of the linkage frame 46 is rotatably mounted on the movable platform via a pin. The outer tube knife moving block 44 and the inner tube moving block 45 are located on opposite sides of the linkage frame 46. One end of the linkage frame 46 is provided with a first guide hole 49, and the other end... The inner tube 26 is provided with a second guide hole 50. The first guide hole 49 is located on one side of the outer tube knife moving block 44. A first guide post is provided on the outer tube knife moving block 44, extending into the first guide hole 49 and moving within the first guide hole 49. The second guide hole 50 is located on one side of the inner tube moving block 45. A second guide post is provided on the inner tube moving block 45, extending into the second guide hole 50 and moving within the second guide hole 50. The linkage driver 47 is mounted on the moving platform and is connected to the inner tube moving block 45 to drive the inner tube moving block 45 to move. Through the linkage frame 46, the inner tube moving block 45 and the outer tube knife moving block 44 form a disengaging or engaging motion. Thus, through the action of the linkage drive mechanism, when the front end of the inner tube 26 moves forward, the front end of the outer tube knife moves backward, and when the front end of the inner tube 26 moves backward, the front end of the outer tube knife moves forward.

[0048] In order to improve the driving stability of the linkage drive mechanism, the linkage frame 46 and the linkage driver 47 are arranged in two sets above the moving platform. One linkage driver 47 is connected to one side of the inner tube moving block 45, and the other linkage driver 47 is connected to the other side of the inner tube moving block 45. The linkage driver 47 in this application can be any of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0049] In this application, to enable the inner tube 26 to extend and retract independently, an inner tube drive mechanism is designed, which works independently of the linkage drive mechanism. Specifically, the inner tube drive mechanism includes an inner tube driver 51 and an inner tube drive block 52. The inner tube drive block 52 is slidably mounted on the inner tube moving block 45, and the sliding direction of the inner tube drive block 52 is the same as the extension and retraction direction of the inner tube. A sliding groove 53 is provided in the middle of the inner tube moving block 45, and the inner tube drive block 52 is slidably disposed in the sliding groove 53. Two vertically arranged stops are provided on the inner tube moving block 45, forming a sliding groove between the two stops, allowing the inner tube drive block 52 to reciprocate within the sliding groove. A slot 54 is provided on the inner tube drive block 52, and a groove is provided at the tail end of the inner tube. Insert the inner tube 26 into the slot, and the snap-fit ​​part 55 is located in the slot 54. The snap-fit ​​part 55 is in the slot to snap the tail end of the inner tube 26 onto the inner tube drive block 52. A connecting seat 56 is fixedly provided on one side of the inner tube moving block 45. The inner tube driver 51 is a cylinder. The body of the inner tube driver 51 is assembled on the inner tube drive block 52. The drive end of the inner tube driver 51 is connected to the connecting seat. When the inner tube driver 51 extends or retracts, it drives the inner tube to extend or retract within the intermediate tube 27 through the inner tube drive block 52, thereby realizing the independent extension or retraction of the inner tube. Since the inner tube drive block 52 is slidably disposed on the inner tube moving block 45, the inner tube drive mechanism and the linkage drive mechanism will not interfere with each other in terms of movement.

[0050] In this application, in order to realize the movement of the intermediate tube 27, an intermediate tube fixing block 57 is fixedly assembled on the moving platform. The intermediate fixing block 57 is located on the moving platform between the outer tube cutting block 44 and the inner tube moving block 45. An intermediate tube limiting groove 58 is provided in the intermediate tube fixing block 57. An intermediate tube stage 59 is provided at the tail end of the intermediate tube 27 and inserted into the intermediate tube limiting groove 58 and restricted by the intermediate tube stage 59 in the intermediate tube limiting groove 58. A limiting block 60 for constraining the intermediate tube stage 59 in the intermediate tube limiting groove is also fixedly connected to the intermediate tube fixing block 57, so that the intermediate tube moves when the intermediate tube fixing block 57 moves. In this application, the intermediate tube driving mechanism adopts a platform driving mechanism. When the platform driving mechanism drives the moving platform to move, the intermediate tube fixing block moves accordingly, thereby driving the movement of the intermediate tube, so as to save the setting of the driving mechanism.

[0051] In this application, to ensure the stability of the extension and retraction of the inner tube 26, the intermediate tube, and the outer tube cutter, the inner tube 26, the intermediate tube, and the outer tube cutter are arranged coaxially and pass through the first guide seat 36. The first guide seat 36 has a guide channel 61, and a guide sleeve 62 is installed in the guide channel 61. The outer wall of the outer tube cutter and the inner wall of the guide sleeve 62 form a sliding fit. The inner diameter of the guide channel 61 is slightly larger than the outer diameter of the outer tube cutter, with only a movement gap. Here, the first guide seat 36 is used to guide the tube cutter, reducing the need for additional guide components.

[0052] In this application, a collection chamber 63 is provided above the base 13, and the collection chamber 63 is located below the cutter holder. In a specific implementation, the collection chamber is arranged in the accommodating space between a pair of supports to further reduce the space occupied by the device. A stripping member 64 is provided on the cutter holder to peel the shielding mesh cut from the cable into the collection chamber. The stripping member 64 has a stripping through hole 65 with a diameter slightly larger than the outer diameter of the outer tube cutter. The two ends of the stripping member are bent and fixed to one side of the cutter holder. The stripping through hole 65 is located in the middle of the stripping member and above the collection chamber. The stripping member prevents the cut shielding mesh from being carried out with the tube cutter as it is retracted.

[0062] 7. Driven by the linkage mechanism, the outer tube cutter cooperates with the cutter disc inside the cutter holder to cut the shielding mesh located between the two.

[0063] 8. Inner tube / middle tube linkage, that is, the inner tube / middle tube and the front end of the outer tube knife are flush, and the shielding mesh on the core is turned over, turning the shielding mesh to a 90° state;

[0064] 9. The outer tube knife moves backward (opposite to the cutting), and the cut shielding mesh on the outer tube knife is peeled off by the peeling component and falls into the collection chamber;
