Description

Technical Field

[0001] The invention relates to the field of automobile cable processing and assembly, and in particular to an automobile cable peeling and bushing pressing machine and a use method thereof. Background Art

[0002] Automobile cables are used to stabilize steel structures or stabilize and tension membrane products. Their main structures include steel strands, cable anchors, cable heads, etc. They are mainly divided into: throttle cables (wires), clutch cables (wires), brake cables (wires), odometer flexible shafts, gear selection cables, etc. There are special buckles at both ends of the cables corresponding to different models. For cables of the same category, the models are mainly distinguished by length and ball head buckles.

[0003] In the actual production process of automobile cables, the fasteners at both ends of the cables are installed last. Before that, the cables need to be covered with an outer protective layer to protect the steel strands inside. In this production process, heat shrink tubing is usually used for covering. Finally, the excess heat shrink tubing at both ends of the steel strands needs to be cut off and peeled off. In the existing design, the cables are often clamped at two points, that is, the two ends are clamped and the two ends are peeled. The following problems may occur when peeling in this way:

[0004] When the clamps at both ends of the automobile cable peel off the outer protective layer, since the automobile cable itself is cylindrical, it is necessary to move the automobile cable body or the processing tool in a circular direction. Traditional processing equipment needs to integrate multiple electrical components to achieve the peeling work, which unnecessarily increases the complexity of the device structure. At the same time, since the cable needs to be tightened during the processing, the force points acting on the cable are concentrated at its two ends when the traditional processing device processes the cable. At this time, the outer coating of the automobile cable will become straight together with the internal steel strands, which will cause the coating in the middle of the cable to wrinkle. Finally, since bushings need to be installed at both ends of the automobile cable, the peeling process of the automobile cable cannot be effectively combined with the bushing press-fitting, resulting in complicated traditional processing procedures.

[0005] In view of this, it is necessary for us to design an automobile cable stripping and bushing pressing machine. Summary of the invention

[0024] S1: Before the device runs, the operator respectively clamps the two ends of the automobile cable to the clamping mechanism, and then the power motor starts and drives the power mechanism to run.

[0028] First: The device has a high integration degree, simplifies the device structure, and only uses one power motor to drive the device to perform peeling work, enhancing the linkage of the device, reducing the use of electrical components in the device, and facilitating mass production;

[0029] Second: The device drives the automobile cable to rotate through the combined action of the upper pressing power wheel and the lower pressing power wheel, and the circular cutting blade can rotate simultaneously to ensure the cutting of the outer covering protection layer.

[0030] Thirdly: When the device is processing, it drives the automotive cable to rotate, and the operator can detect whether the bushings pressed at both ends of the automotive cable are disengaged. It integrates the inspection of bushing pressing and simplifies the processing procedure. Description of the Drawings

Detailed implementation manners

[0041] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation manners.

[0042] Refer to Figures 1 to 9 , an automobile cable peeling and bushing pressing machine, comprising:

[0043] A support platform 1, which is arranged horizontally, and an avoidance sinking groove 2 is formed in the middle of the support platform 1;

[0044] Two support frames 3, which are symmetrically arranged at the lower end of the support platform 1 and play a supporting role;

[0045] A power motor 4, which is arranged vertically at the lower end of the middle of the support platform 1;

[0046] A power mechanism 5, which is arranged in the avoidance sinking groove 2 and is connected to the output end of the power motor 4;

[0047] Two positioning and driving components 12 are arranged above the support platform 1 and include two upper positioning and driving mechanisms 13 and two lower positioning and driving mechanisms 19. The two upper positioning and driving mechanisms 13 are staggered on both sides of the vehicle cable. The two lower positioning and driving mechanisms 19 are symmetrically arranged in the axial direction of the vehicle cable. The upper positioning and driving mechanism 13 includes two upper pressing power wheels 18, and the lower positioning and driving mechanism 19 includes a lower pressing power wheel 25. The two upper pressing power wheels 18 apply forces to the vehicle cable from top to bottom, and the lower pressing power wheel 25 applies forces to the vehicle cable from bottom to top;

[0048] Two elastic cutting mechanisms 26 are arranged on both sides of the power mechanism 5 and connected to the power mechanism 5. Each of the two elastic cutting mechanisms 26 includes a circular cutting blade 35, and the circular cutting blade 35 can stably strip the outer covering of the vehicle cable;

[0049] Two clamping mechanisms 43 are respectively arranged at one ends of the two elastic cutting mechanisms 26 away from the power mechanism 5. The clamping mechanisms 43 can straighten and tension the two ends of the vehicle cable and position them.

[0050] Before the device operates, the operator first connects the two ends of the vehicle cable to the two clamping mechanisms 43 respectively. During this process, since the vehicle cable itself is a flexible rope, the vehicle cable can bend itself to avoid the two upper pressing power wheels 18 and the lower pressing power wheel 25 during installation. Subsequently, when the two ends of the vehicle cable are positioned by the two clamping mechanisms 43, the vehicle cable will be tightened and straightened. At this time, the power motor 4 is started, and the two clamping mechanisms 43 will clamp and fix the two ends of the vehicle cable. At the same time, the power mechanism 5 is started and drives the upper pressing power wheels 18 and the lower pressing power wheel 25 to rotate. The upper pressing power wheel 18 applies a downward extrusion force to the tightened vehicle cable, and the lower pressing power wheel 25 applies an upward extrusion force to the tightened vehicle cable. At this time, the vehicle cable will rotate itself as the upper pressing power wheels 18 and the lower pressing power wheel 25 rotate. When the vehicle cable rotates, the two circular cutting blades 35 will press against the outside of the vehicle cable and strip the outer protective layer of the vehicle cable. When the vehicle cable rotates, the operator can also check whether the bushings fixedly installed at the two ends of the vehicle cable are disengaged due to rotation. If they are disengaged, the disengaged bushings can be press-fitted again after the vehicle cable is stripped.

[0051] In order to integrate the power source, simplify the electrical structure in the device, and enhance the integration degree of the device, the following features are specifically set:

[0052] The power mechanism 5 includes a power shaft 6, a driving gear 8, two first gears 9, two second gears 10 and two third gears 11. The power shaft 6 is fixedly connected to the output end of the power motor 4 through a coupling. The driving gear 8 is key-connected to the power shaft 6. The power gear 7 is arranged at the upper end of the driving gear 8 and is key-connected to the power shaft 6. The two first gears 9 are respectively arranged on both sides of the driving gear 8 and are simultaneously meshed with the driving gear 8. The two second gears 10 are respectively arranged beside the two first gears 9 and are simultaneously meshed with the first gears 9. The two third gears 11 are respectively arranged on both sides of the first gear 9 and are simultaneously meshed with the driving gear 8. When the device operates, the power motor 4 starts and drives the power shaft 6 to rotate. The rotation of the power shaft 6 drives the connected driving gear 8 and power gear 7 to rotate. The rotation of the driving gear 8 simultaneously drives the two first gears 9 and the two third gears 11 meshed with it to rotate. The rotation of the two first gears 9 respectively drives the two second gears 10 meshed with them to rotate.

[0053] In order to enable the vehicle cable to rotate while in a taut state, the upper pressing power wheel 18 needs to rotate. For the upper pressing power wheel 18, the following features are specifically set:

[0054] The upper positioning transmission mechanism 13 further includes a first transmission shaft 14, a transmission worm 15, a transmission worm wheel 16 and a second transmission shaft 17. The first transmission shaft 14 is key-connected to the second gear 10. The transmission worm 15 is coaxially sleeved on the upper part of the first transmission shaft 14. The transmission worm wheel 16 is arranged beside the transmission worm 15 and is meshed with it. The second transmission shaft 17 is key-connected to the transmission worm wheel 16. The two upper pressing power wheels 18 are respectively arranged at both ends of the transmission worm wheel 16 and are key-connected to the second transmission shaft 17. When the device operates, the rotation of the second gear 10 drives the first transmission shaft 14 to rotate. The rotation of the first transmission shaft 14 drives the connected transmission worm 15 to rotate. The rotation of the transmission worm 15 drives the meshed transmission worm wheel 16 to rotate. The rotation of the transmission worm wheel 16 drives the second transmission shaft 17 key-connected to it to rotate. The rotation of the second transmission shaft 17 drives the two upper pressing power wheels 18 key-connected to it to rotate. The two upper pressing power wheels 18 are in interference connection with the taut vehicle cable. At this time, the two upper pressing power wheels 18 will apply a downward pressing force to the taut vehicle cable.

[0055] In order to cooperate with the upper pressing power wheel 18 to apply a pressing force to the vehicle cable, the lower pressing power wheel 25 also needs to rotate. For the lower pressing power wheel 25, the following features are specifically set:

[0056] The lower positioning drive mechanism 19 includes a third transmission shaft 20, a first bevel gear 21, a second bevel gear 22, a drive gear 23, and a transmission gear 24. The third transmission shaft 20 is key-connected to the third gear 11. The first bevel gear 21 is arranged at the upper end of the third gear 11 and is key-connected to the third transmission shaft 20. The second bevel gear 22 is arranged beside the first bevel gear 21 and meshes with it. The drive gear 23 is connected to the second bevel gear 22 through a pin shaft. The transmission gear 24 is arranged at the upper end of the drive gear 23 and meshes with it. The lower pressing power wheel 25 is coaxially connected to the transmission gear 24 through a short pin. When the device operates, the rotation of the third gear 11 drives the third transmission shaft 20 to rotate. The rotation of the third transmission shaft 20 drives the first bevel gear 21 connected to it to rotate. The rotation of the first bevel gear 21 drives the second bevel gear 22 meshing with it to rotate. The second bevel gear 22 drives the drive gear 23 to rotate through a pin shaft. The rotation of the drive gear 23 drives the transmission gear 24 meshing with it to rotate. The transmission gear 24 drives the lower pressing power wheel 25 to rotate through a short pin. The lower pressing power wheel 25 is in interference connection with the tightened vehicle cable. The lower pressing power wheel 25 applies an upward pressing force to the tightened vehicle cable. The lower pressing power wheel 25 cooperates with the upper pressing power wheel 18, enabling the vehicle cable to perform a self-rotation movement in a tightened state.

[0057] To achieve the rotation of the circular cutting blade 35 and ensure that the cut of the outer protective layer outside the vehicle cable can remain flat, the following features are specifically set:

[0058] The elastic cutting mechanism 26 further includes a first driving pulley 27, a first driven pulley 28, a third bevel gear 29, a fourth bevel gear 30, a second driving pulley 31, a second driven pulley 32, a linkage short shaft 33 and a linkage bracket 34. The first driving pulley 27 is connected to the first gear 9 by a pin shaft. The first driven pulley 28 is connected to the first driving pulley 27 by a belt for transmission. The third bevel gear 29 is arranged at the upper end of the first driven pulley 28 by a pin shaft. The fourth bevel gear 30 meshes with the third bevel gear 29. The second driving pulley 31 is connected to the fourth bevel gear 30 by a pin shaft. The second driven pulley 32 is connected to the second driving pulley 31 by a belt for transmission. The linkage short shaft 33 is key-connected to the second driven pulley 32. The lower end of the linkage bracket 34 is rotatably connected to the linkage short shaft 33. The circular cutting blade 35 is key-connected to one end of the linkage short shaft 33 close to the cable head of the vehicle cable. When the device operates, the rotation of the first gear 9 drives the first driving pulley 27 to rotate. The first driving pulley 27 drives the first driven pulley 28 to rotate through the belt. The rotation of the first driven bevel gear drives the connected third bevel gear 29 to rotate. The rotation of the third bevel gear 29 drives the meshed fourth bevel gear 30 to rotate. The rotation of the fourth bevel gear 30 drives the connected second driving pulley 31 to rotate. The second driving pulley 31 drives the second driven pulley 32 to rotate through the belt. The rotation of the second driven pulley 32 drives the connected linkage short shaft 33 to rotate. The rotation of the linkage short shaft 33 drives the connected circular cutting blade 35 to rotate. When the circular cutting blade 35 rotates, it can cut and strip the plastic skins at both ends of the vehicle cable.

[0059] In order to ensure that the circular cutting blade 35 can always be close to the outer protective layer to achieve a complete excision of the outer protective layer, the following features are specifically set:

[0060] The elastic cutting mechanism 26 further includes a limit short pin 36, a pressing spring 37, a positioning support 42, a limit baffle 39, a limit support 40, a positioning frame and two limit long shafts 38. The limit short pin 36 is fixedly inserted at the upper end of the linkage support 34. The limit baffle 39 is arranged above the linkage support 34. The pressing spring 37 is sleeved outside the limit short pin 36. One end of the pressing spring 37 abuts against the linkage support 34, and the other end abuts against the limit baffle 39. The upper end of the limit short pin 36 is slidably connected to the limit baffle 39. One ends of the two limit long shafts 38 are respectively fixedly connected to the limit baffle 39, and the other ends are respectively slidably connected to the linkage support 34. The positioning support 42 is arranged beside the second driven pulley 32. The limit support 40 is fixedly connected to the upper end of the positioning support 42. The limit baffle 39 is connected to the upper end of the limit support 40 through a backing plate. The tensioner 41 is arranged beside the second driving pulley 31 and abuts against the belt at the second driving pulley 31. When the device operates, as the circular cutting blade 35 cuts off the outer covering layer outside the automotive cable, the circular cutting blade 35 will gradually move in the direction close to the axis of the automotive cable to prevent the outer covering layer from not being completely cut off. During this process, as known from the previous text, the limit baffle 39 remains stationary, and the elastic force of the pressing spring 37 will push the linkage support 34 to move. The two limit long shafts 38 can prevent the linkage support 34 from camming during the movement. The movement of the linkage support 34 will drive the linkage short shaft 33 to move, and the movement of the linkage short shaft 33 will drive the circular cutting blade 35 to move. The tensioner 41 can prevent the belt at the second driven pulley 32 from loosening due to the movement of the linkage short shaft 33 and enhance the stability of the device.

[0061] To enhance the integration of the device and enable the power motor 4 to clamp the gripper 54 without shutting down the machine, and to prevent the gripper 54 from continuously exerting force after clamping the automotive cable, causing local overload and damaging the device body, the following features are specifically set:

[0062] The clamping mechanism 43 includes a power rack 44, a power tooth block 47, a driving rack 48, a positioning baffle 49, a transfer gear 50, two limit insertion shafts 45 and two limit springs 46. The power rack 44 is arranged beside the power gear 7 and meshes with it. The power tooth block 47 is arranged at one end of the power rack 44. For the two limit insertion shafts 45, one end of each is fixedly connected to the power rack 44 respectively, and the other end of each is slidably connected to the power tooth block 47. The two limit springs 46 are respectively sleeved outside the two limit insertion shafts 45. One end of each of the two limit springs 46 abuts against the power rack 44, and the other end abuts against the power tooth block 47. The driving rack 48 is connected to the end of the power rack 44 away from the power tooth block 47 through a backing plate. The transfer gear 50 is arranged beside the driving rack 48 and meshes with it. The positioning baffle 49 is fixedly arranged at the end of the driving rack 48 away from the power tooth block 47. When the device operates, the rotation of the power gear 7 will drive the power rack 44 meshing with it to move. The movement of the power rack 44 will drive the driving rack 48 connected to it to move. The movement of the driving rack 48 will drive the transfer gear 50 meshing with it to rotate. As the power rack 44 moves, the end of the power rack 44 away from the power gear 7 will abut against the positioning baffle 49, and the positioning baffle 49 will prevent the power rack 44 from moving forward continuously. However, at this time, the power gear 7 will not stop rotating, and the power gear 7 will continuously contact the power tooth block 47. The power tooth block 47 will continuously move back and forth under the action of the two limit springs 46. At this time, the rotation of the power gear 7 will no longer drive the power rack 44 to displace. During this process, the two limit insertion shafts 45 can ensure that the power tooth block 47 will not move chaotically when moving.

[0063] In order to realize the mutual approach of the holding claws 54 and enhance the stability of the device body, the following features are specifically set:

[0064] The clamping mechanism 43 further includes a connecting gear 51, two connecting racks 52, two connecting supports 53, two clamping claws 54, two connecting shaft seats 55 and two limiting connecting shafts 56. The connecting gear 51 is connected to the transfer gear 50 through a pin shaft. The two connecting racks 52 are symmetrically arranged on both sides of the connecting gear 51 and meshed with it. The two connecting supports 53 are respectively arranged at the upper ends of the two connecting racks 52. Each connecting support 53 is fixedly connected to one connecting rack 52 and slidably connected to the other connecting rack 52. The two clamping claws 54 are respectively arranged at the upper ends of the two connecting supports 53. The two connecting shaft seats 55 are respectively fixedly arranged at both ends of the two clamping claws 54. One end of each of the two limiting connecting shafts 56 is fixedly connected to the two connecting supports 53 through a shaft seat, and the other end is respectively slidably connected to the corresponding connecting shaft seat 55. When the device is running, when the power rack 44 moves, the movement of the power rack 44 will drive the transfer gear 50 to rotate. The rotation of the transfer gear 50 will drive the connecting gear 51 to rotate. The rotation of the connecting gear 51 will drive the two connecting racks 52 to move towards each other. The movement of the two connecting racks 52 towards each other will drive the two connecting supports 53 to move towards each other. The movement of the two connecting supports 53 towards each other will drive the two clamping claws 54 to move towards each other. After the two clamping claws 54 move towards each other, they will clamp the end of the automotive cable. During this process, the two clamping claws 54 are rotatably connected to the end of the automotive cable to prevent the two clamping claws 54 from blocking the rotation of the automotive cable. The two limiting connecting shafts 56 can improve the stability of the movement of the clamping claws 54.

[0065] An automotive cable stripping and bushing pressing machine further includes its usage method:

[0066] S1: Before the device runs, the operator respectively engages the two ends of the automotive cable with the clamping mechanism 43, and then the power motor 4 starts and drives the power mechanism 5 to run. During this process, since the automotive cable itself is a flexible long rope, during the installation process, the operator can first twist the cable body of the automotive cable, and then fix and engage the tightened automotive cable on the two clamping mechanisms 43.

[0067] S2: When the power motor 4 starts, the power mechanism 5 starts and drives the clamping mechanism 43 to clamp the two ends of the automotive cable. At the same time, the lower pressing power wheel 25 and the two upper pressing power wheels 18 rotate and drive the tightened automotive cable to rotate. And during the rotation of the automotive cable, the circular cutting blade 35 will exert a continuous force on the outer protective layer outside the automotive cable. Finally, the circular cutting blade 35 completes the stripping work on the automotive cable.

[0068] S3: During the operation of the device, the operator can also check whether the bushings fixedly installed at both ends of the automotive cable fall off during the rotation of the automotive cable. If the bushings at both ends fall off, the operator can reinstall the bushings after the stripping of the automotive cable is completed.

[0069] The working principle of this device is as follows: The operator first places the end of the automotive cable between the two clamping jaws 54, and then the power motor 4 starts and drives the two clamping jaws 54 to move towards each other. During this process, the operator can finely adjust the automotive cable to ensure that the outer protective layer at both ends can be cut by the circular cutting blade 35 when it is tightened.

[0070] When the power motor 4 starts, the power motor 4 can drive all the upper tightening power wheels 18 and the lower tightening power wheels 25 to rotate simultaneously. At this time, all the upper tightening power wheels 18 apply a tightening force to the automotive cable from top to bottom, and all the lower tightening power wheels 25 apply a tightening force to the automotive cable from bottom to top, and the automotive cable will rotate under the balance of the two forces.

[0071] Meanwhile, the circular cutting blades 35 at both ends of the automotive cable cut the outer protective layer outside the automotive cable under the action of the second driven pulley 32. It can be seen that the simultaneous rotation of the automotive cable and the circular cutting blades 35 can not only improve the cutting efficiency but also ensure the smoothness of the cut. During the cutting process, the circular cutting blades 35 can gradually approach the axis direction of the automotive cable under the action of the tightening spring 37, and finally the circular cutting blades 35 will peel off the outer protective layer. It should be noted that the hardness of the circular cutting blades 35 should be less than the hardness of the automotive cable body material to prevent the circular cutting blades 35 from damaging the automotive cable body.

[0072] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
