Description

Technical Field

[0001] The invention relates to the field of manufacturing technology for a shifter cable, and in particular to a shifter cable oiling and threading machine and a use method thereof. Background Art

[0002] The shift cable is an important part of the automobile transmission system. Its function is to transmit the operation of the shifter assembly to the transmission shift fork, thereby controlling the change in speed of the car during driving and achieving the purpose of safe and rapid driving. Nowadays, cars usually have more gears, which requires the shift cable to have a very accurate stroke to achieve the accuracy of shifting and thus ensure driving stability. The two ends of the general automobile shift cable are joint ring structures, and the outer sleeve of the cable core is provided with a rubber shell, which is called a cable skin.

[0003] Since the cable core needs to be inserted into the cable skin, in the actual production and processing process, the threading process is mostly manual threading or mechanical unified threading. However, manual threading has the disadvantages of low work efficiency and slow threading process. For traditional threading machines, since the cable core itself is a flexible rope body, the cable core will bend and deform during the threading process, affecting the threading effect. In addition, the existing threading machines mostly insert the cable core directly into the stretched cable skin. In this process, since the cable core and the cable skin are interference fit, forced fit can easily cause the cable skin to rupture. Since manual threading is inserted section by section, this problem does not exist.

[0004] Based on this, it is necessary for us to design a shifter cable oiling and threading machine that combines the high quality of manual work with the high efficiency of the threading machine, thereby improving work efficiency without causing the cable skin to rupture. Summary of the invention

[0005] Based on this, it is necessary to provide a shifter cable oiling and threading machine and a method of using the same in response to the existing technical problems.

[0022] A method for using a shifter cable oiling and threading machine, including the shifter cable oiling and threading machine described above, and also including the following method of use:

[0023] S1: The operator should first fix one end of the cable skin on the outside of the positioning gear ring through a clamping hoop, and then the positioning gear ring will rotate to drive the cable skin to rotate;

[0024] S2: The operator then places one end of the cable core at the clamping mechanism and the other end at a driving progressive mechanism closest to the positioning gear ring.

[0025] S3: Finally, the operator starts the driving motor, which will drive the moving rack to move back and forth. When the moving rack moves, it will drive the moving gear to rotate. When the moving gear rolls along the fixed rack, it will drive the cable core to move toward the cable skin in sections.

Finally, the cable core will be completely inserted into the cable skin.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] Firstly, the device uses the linkage between the mobile gear and the power ratchet, and cooperates with the one-way self-locking function of the power ratchet to insert the cable core into the cable skin section by section, while imitating the manual threading action, it also liberates the labor of workers and improves product quality;

[0028] Second, the power residual teeth, power gear and residual tooth gear ring in the device cooperate to realize the reciprocating clamping action of the two clamping claws, and after combining with the moving gear and the power ratchet, the continuous pushing of the cable core is completed. During the continuous pushing of the cable core, a number of clamping claws work together to continuously push the cable core into the cable skin, and the device has strong stability;

[0029] Thirdly, the device drives the rope skin to rotate in one direction through the residual tooth ring, while the two coating rollers drive the rope core to rotate in another direction. The rotation directions of the rope skin and the rope core are opposite, which is conducive to smoother threading work and improved work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] refer to Figures 1 to 8 , a shifter cable oiling and threading machine, comprising:

[0042] The reciprocating drive mechanism 1 comprises a drive motor 2 arranged in a vertical state, and the drive motor 2 is fixedly arranged by a motor frame;

[0043] A clamping mechanism 11 is arranged above the driving motor 2 through a bracket, and the clamping mechanism 11 can limit the end of the cable core away from the cable skin;

[0044] A movable rack 23 is arranged on one side of the cable and connected to the reciprocating drive mechanism 1;

[0045] A fixed rack 24, which is arranged on the other side of the cable and fixed by a support frame;

[0046] Two limiting slide rails 25 are respectively fixed above the fixed rack 24 and the movable rack 23 through pads;

[0047] A plurality of driving progressive mechanisms are respectively arranged at equal intervals along the cable axis direction, and each of the driving progressive mechanisms comprises a moving gear 27 and a power ratchet 28. One side of the moving gear 27 is meshed with the fixed rack 24, and the other side is meshed with the moving rack 23. The power ratchet 28 is coaxially fixed to the upper end of the moving gear 27;

[0048] The oiling reversal component 38 is arranged at the end of the cable away from the driving motor 2. The oiling reversal component 38 includes a positioning gear ring 42, a clamping hoop 45 and an oiling mechanism 46. The positioning gear ring 42 is coaxially arranged with the cable. The clamping hoop 45 is coaxially arranged at the end of the positioning gear ring 42 away from the driving motor 2. The clamping hoop 45 can fix the rope skin on the outside of the positioning gear ring 42, and the oiling mechanism 46 can evenly apply lubricating oil to the rope core.

[0049] Before the device is operated, the operator first puts one end of the rope skin on the end of the positioning gear ring 42 away from the drive motor 2, and then tightens the clamping clamp 45 to fix the rope skin. Then the operator clamps one end of the rope core in the clamping mechanism 11. After the device is started, the drive motor 2 starts and drives the moving rack 23 to move closer to the positioning gear ring 42. The moving rack 23 is meshed with the moving gear 27. The movement of the moving rack 23 will drive the moving gear 27 to rotate, and the moving gear 27 will move along the long side direction of the fixed rack 24. The moving gear 27 is fixedly connected to the power ratchet 28. At this time, the power ratchet 28 is locked (i.e., the inner and outer rings of the power ratchet 28 rotate synchronously. The characteristics of the ratchet mechanism are explained in detail in the working principle section below). The cable core is clamped and moves toward the positioning gear ring 42. As the drive motor 2 runs, the reciprocating drive mechanism 1 drives the moving rack 23 to move away from the positioning gear ring 42. At this time, the power ratchet 28 rotates freely (i.e., the inner and outer rings of the power ratchet 28 rotate relative to each other). The rotation of the moving gear 27 will not drive the power ratchet 28 to rotate. The cable core will not be driven by the driving progressive mechanism 26, and the cable stops moving at this time. During the operation of the device, the cable core repeats this process. When the cable moves to the positioning gear ring 42, the oiling mechanism 46 will apply lubricating oil to the outside of the cable core to facilitate the insertion of the cable core into the cable skin. It should be noted that the oiling mechanism 46 will drive the cable core to rotate, and the positioning gear ring 42 will drive the cable skin to rotate in the opposite direction. The cable core and the cable skin are coaxially reversed to facilitate the cable threading process.

[0050] refer to Figure 1 , Figure 3 and Figure 4 In order to drive the movable rack 23 to move back and forth, the following features are specifically set:

[0051] The reciprocating drive mechanism 1 includes a driving gear 3, a reduction gear 4, a transmission gear 5, a transmission crank 6, a linkage slider 7, a linkage slide rod 8 and a supporting bracket 10. The driving gear 3 is arranged above the driving motor 2 and is key-connected to the output end of the driving motor 2. The reduction gear 4 is arranged beside the driving gear 3 and meshes with the driving gear 3. The transmission gear 5 is arranged beside the reduction gear 4 and meshes with the reduction gear 4. The transmission crank 6 is arranged at the lower end of the transmission gear 5. One end of the transmission crank 6 is connected to the transmission gear 5 through a pin shaft. The linkage slider 7 is connected to the other end of the transmission crank 6 through a pin shaft. A limited slide groove 9 is formed in the middle part of the linkage slide rod 8. The linkage slider 7 is slidably connected to the limited slide groove 9. The supporting bracket 10 is fixedly arranged beside the driving motor 2 and slidably connected to one end of the linkage slide rod 8. The other end of the linkage slide rod 8 is fixedly connected to the moving rack 23. When the device is running: the driving motor 2 starts and drives the driving gear 3 to rotate, the driving gear 3 drives the reduction gear 4 meshing with it to rotate, the reduction gear 4 drives the transmission gear 5 meshing with it to rotate, the transmission gear 5 drives the transmission crank 6 to rotate through the pin shaft, the rotation of the transmission crank 6 will drive the linkage slider 7 to move along the limiting slide groove 9, and the linkage slide bar 8 will move back and forth under the action of the linkage slider 7, and the reciprocating movement of the linkage slide bar 8 will drive the connected moving rack 23 to move back and forth. In this process, the supporting bracket 10 plays a limiting role, which can improve the stability of the linkage slide bar 8 when it moves, and the reduction gear 4 can reduce the power provided by the driving motor 2 to prevent the linkage slide bar 8 from moving too fast and causing damage to the device.

[0052] refer to Figure 3 and Figure 5 In order to prevent the cable core from moving at the beginning of the threading work and affecting the subsequent threading work, the following features are specifically set:

[0053] The clamping mechanism 11 includes a clamping cylinder 13, an inclined slider 15, an inclined top block 16, two supporting baffles 14, two limiting baffles 17 and two positioning brackets 12. The two supporting baffles 14 are arranged at the upper end of the reduction gear 4 through a support, and the two positioning brackets 12 are respectively fixedly arranged in the middle of the two supporting baffles 14. The clamping cylinder 13 is fixedly arranged on the side of a supporting baffle 14. The inclined slider 15 is fixedly connected to the output end of the clamping cylinder 13. The two limiting baffles 17 are symmetrically arranged on both sides of the axis of the output end of the clamping cylinder 13. The inclined top block 16 is arranged between the two limiting baffles 17, and the two sides of the inclined top block 16 are respectively slidably connected to the two limiting baffles 17. When the device is running: the two limit baffles 17 play a limiting role, the clamping cylinder 13 is started to push the inclined slider 15 to move, and the inclined slider 15 will abut against the lower end of the inclined top block 16 when moving, and finally the inclined top block 16 will move up with the movement of the inclined slider 15.

[0054] refer to Figure 3 and Figure 5 In order to realize the positioning of the end of the cable core, the end of the cable core is limited by the most stable triangular positioning method, and the following features are specifically set:

[0055] The clamping mechanism 11 also includes an elastic tension spring 18, an auxiliary roller 19, two supporting rollers 22, two reset clamping arms 20 and two positioning rollers 21. The auxiliary roller 19 is rotatably connected to the upper end of the inclined top block 16. The middle parts of the two reset clamping arms 20 are respectively hinged to the two positioning brackets 12. The two positioning rollers 21 are respectively rotatably connected to the upper ends of the two reset clamping arms 20. The two supporting rollers 22 are respectively rotatably connected to the lower ends of the two reset clamping arms 20. The two supporting rollers 22 are respectively abutted against the side walls of the inclined top block 16. The two ends of the elastic tension spring 18 are respectively connected to the lower ends of the two reset clamping arms 20. When the device is in operation: as the inclined top block 16 moves upward, the auxiliary roller 19 will abut against the lower end of the cable, and the elastic tension spring 18 will drive the two reset clamping arms 20 to always keep close to each other. In this process, the two support rollers 22 will abut against the side walls of the inclined top block 16, and drive the two reset clamping arms 20 to rotate around the middle as the inclined top block 16 moves upward. The rotation of the two reset clamping arms 20 will drive the two positioning rollers 21 to abut against the cable. At this time, the two positioning rollers 21 and the auxiliary roller 19 form a triangular positioning for the cable, so that the cable does not move in the initial stage of movement.

[0056] refer to Figure 1 , Figure 3 , Figure 7 and Figure 8 In order to cooperate with the power ratchet 28 to realize the threading work of the cable core, the following features are specifically set:

[0057] The driving progressive mechanism 26 also includes a power shaft 29, a moving platform 30, a power residual tooth 31, a power gear 32 and a residual tooth ring 33. The moving gear 27 is fixedly connected to the outer ring of the power ratchet 28, the power shaft 29 is keyed to the inner ring of the power ratchet 28, the power shaft 29 is rotatably connected to the moving gear 27, the moving platform 30 is rotatably connected to the power shaft 29, both ends of the moving platform 30 are slidably connected to the two limiting slide rails 25, the power residual tooth 31 is keyed to the upper end of the power shaft 29, the power gear 32 is arranged beside the power residual tooth 31 and meshes with the power residual tooth 31, the residual tooth ring 33 is coaxially arranged with the power residual tooth 31, the residual tooth ring 33 is connected to the power shaft 29 through a bracket, and the residual tooth ring 33 meshes with the power gear 32. It should be noted that the inner ring and the outer ring of the power ratchet 28 can rotate relative to each other and rotate synchronously (the characteristic of ratchet machinery is that the ratchet can only rotate in one direction. In this device, the outer ring and the inner ring of the power ratchet 28 are matched by a pawl. When the outer ring of the power ratchet 28 rotates forward, the pawl does not conflict with the side wall of the inner ring. At this time, the outer ring and the inner ring can rotate relative to each other. When the outer ring of the power ratchet 28 rotates reversely, the pawl conflicts with the side wall of the inner ring. At this time, the inner ring and the outer ring of the power ratchet 28 are relatively stationary, that is, the rotation of the outer ring will drive the inner ring to rotate synchronously. Rotation), when the device is running, when the mobile rack 23 moves toward the positioning gear ring 42, the rotation of the mobile gear 27 will drive the outer ring of the power ratchet 28 to rotate. At this time, the inner and outer rings of the power ratchet 28 can rotate synchronously, that is, the rotation of the mobile gear 27 will drive the outer ring of the power ratchet 28 connected thereto to rotate. Since the inner and outer rings of the power ratchet 28 rotate synchronously, the rotation of the mobile gear 27 can drive the power shaft 29 to rotate through the power ratchet 28. At this time, the mobile platform 30 is displaced along the long side direction of the limiting slide rail 25 close to the positioning gear ring 42. On the contrary, when the moving rack 23 moves in the direction away from the positioning gear ring 42, the moving gear 27 rotates to drive the outer ring of the power ratchet 28 to rotate in the opposite direction. According to the characteristics of the ratchet mechanism described above, it can be seen that at this time, the inner and outer rings of the power ratchet 28 slide relative to each other, that is, the rotation of the moving gear 27 cannot drive the power shaft 29 to rotate through the power ratchet 28. At this time, the moving platform 30 moves away from the positioning gear ring 42 along the long side direction of the limiting slide rail 25. When the power ratchet 28 drives the power shaft 29 to rotate, the rotation of the power shaft 29 will drive the power residual teeth 31 and the residual tooth gear ring 33 connected thereto to rotate at the same time. It can be seen that the power gear 32 is meshed with the power residual teeth 31 and the residual tooth gear ring 33 at the same time. It can also be seen that the power gear 32 is meshed with the power residual teeth 31 externally and meshed with the residual tooth gear ring 33 internally. As the power residual teeth 31 and the residual tooth gear ring 33 alternately mesh with the power gear 32, the power gear 32 will rotate alternately in two directions.

[0058] refer to Figure 1 , Figure 3 and Figure 8 In order to realize the segment-by-segment movement of the cable core, the following features are specifically set:

[0059] The driving progressive mechanism 26 also includes a clamping gear 34, two clamping racks 35, two clamping claws 36 and four movable limiting shafts 37. The clamping gear 34 is coaxially fixedly arranged on the upper end of the power gear 32. The two clamping racks 35 are symmetrically arranged on both sides of the clamping gear 34 and mesh with the clamping gear 34 at the same time. The two clamping claws 36 are respectively fixedly connected to the upper ends of the two clamping racks 35. The four movable limiting shafts 37 are respectively arranged in groups of two at one end of the two clamping claws 36 away from the rope core. The two movable limiting shafts 37 are fixedly connected to the clamping claws 36 through an axle seat at one end, and slidably connected to the moving platform 30 through the axle seat at the other end. When the device is running: the rotation of the power gear 32 will drive the clamping gear 34 to rotate, the rotation of the clamping gear 34 will drive the two clamping racks 35 meshing therewith to move, the movement of the two clamping racks 35 will drive the two clamping claws 36 to move, and the movement of the two clamping claws 36 will clamp or loosen the cable core. When the movable rack 23 moves toward the direction close to the positioning gear ring 42, the movement of the movable rack 23 will drive the movable gear 27 to rotate, and the movable gear 27 drives the movable platform 30 to move through the power shaft 29. However, at this time, the inner and outer rings of the power ratchet 28 rotate at the same time, and the rotation of the movable gear 27 will drive the power shaft 29 to rotate. When the power shaft 29 rotates, the power residual teeth 31 and the residual tooth gear ring 33 are alternately meshed with the power gear 32. The power gear 32 will drive the clamping rack 35 to move in two directions through the clamping rack 35. At this time, the two clamping claws 36 will sequentially perform four actions: approaching each other, being stationary, moving away from each other, and being stationary for the second time. In the "stationary" stage, the two clamping claws 36 will drive the cable core to move toward the positioning gear ring 42. At this time, the end of the cable core away from the drive motor 2 will be inserted into the cable skin. Then the moving rack 23 moves away from the positioning gear ring 42, and the movement of the moving rack 23 will continue to drive the moving gear 27 to rotate, but at this time the inner and outer rings of the power ratchet 28 can rotate relatively, and the power shaft 29 will not be driven by the power ratchet 28. When the power shaft 29 does not rotate, the two clamping claws 36 are always in the "secondary static" stage. At this time, the mobile platform 30 moves away from the positioning gear ring 42 under the drive of the power shaft 29, and the two clamping claws 36 slide relative to the cable core. Repeat the above process, and the cable core will be inserted into the cable skin one end at a time to complete the segmented threading of the cable.

[0060] refer to Figure 1 , Figure 2 and Figure 6In order to fix the rope skin and enable it to rotate during the subsequent threading process, the following features are specifically set:

[0061] The oiling reversing assembly 38 includes a power motor 39, an active gear hob 40, a first power gear hob 41, a second power gear hob 44 and two reversing gear hobs 43. The power motor 39 is horizontally arranged at one end of the positioning gear ring 42 away from the drive motor 2. The active gear hob 40 is keyed to the output end of the power motor 39. The first power gear hob 41 and the second power gear hob 44 are symmetrically arranged on both sides of the positioning gear ring 42. The two reversing gear hobs 43 are respectively arranged on one side of the first power gear hob 41 and the second power gear hob 44 close to the positioning gear ring 42. The two reversing gear hobs 43 are respectively meshed with the first power gear hob 41 and the second power gear hob 44, and the two reversing gear hobs 43 are simultaneously meshed with the positioning gear ring 42. When the device is running: the power motor 39 starts and drives the active gear hob 40 to rotate. The rotation of the active gear hob 40 will drive the first power gear hob 41 meshing with it to rotate. The rotation of the first power gear hob 41 will drive the reversing gear hob 43 meshing with it to rotate. The rotation of the reversing gear hob 43 will drive the positioning gear ring 42 meshing with it to rotate. The positioning gear ring 42 will drive another reversing gear hob 43 to rotate. The rotation of the other reversing gear hob 43 will drive the second power gear hob 44 meshing with it to rotate. The positioning gear ring 42 will drive the pull rope skin to rotate through the clamping hoop 45.

[0062] refer to Figure 2 and Figure 6 In order to facilitate the assembly of the cable core and cable skin, the following features are specifically set:

[0063] The oiling mechanism 46 includes an oil tank 48, two oil pipes 49, two oil valves 50 and two smear rollers 47. One of the two smear rollers 47 is coaxially fixed to the first power gear hob 41, and the other is coaxially fixed to the second power gear hob 44. The oil tank 48 is arranged below the positioning gear ring 42. The two oil valves 50 are respectively arranged above the two smear rollers 47 through brackets. One end of the oil pipe 49 is connected to the oil tank 48, and the other end is connected to the input end of the oil valve 50. The output end of the oil valve 50 is aligned with the upper end of the smear roller 47. When the device is running, the first power hob 41 and the second power hob 44 will respectively drive the two smear rollers 47 to rotate, and the two smear rollers 47 will squeeze and resist the cable core at the same time. The rotation of the two smear rollers 47 will drive the cable core to rotate, and the oil valve 50 will extract the lubricating oil in the oil tank 48 through the oil pipe 49 and spray it on the outside of the cable core. In the process of the two smear rollers 47 resisting the cable core, the cable core will evenly apply the lubricating oil on the outside of the cable core. It can be seen that the rotation direction of the cable skin is opposite to that of the cable core, and the two cooperate, which is more conducive to the threading work.

[0064] The working principle of this device is as follows: before the device is operated, the operator first fixes one end of the rope skin on the end of the positioning gear ring 42 away from the drive motor 2 through the clamping hoop 45, and then the power motor 39 starts and drives the positioning gear ring 42 to rotate, and then the operator places one end of the rope core between the two clamping claws 36 closest to the positioning gear ring 42.

[0065] The other end of the cable core can be clamped in a triangular positioning form by the auxiliary roller 19 and the two positioning rollers 21 as the clamping cylinder 13 is started. At this time, the cable core can be initially positioned to ensure that the cable core will not move when it is inserted into the cable skin in the initial stage. Then the driving motor 2 is started and drives the moving rack 23 to move through the linkage slide rod 8.

[0066] During the movement, the moving rack 23 will drive the meshing moving gear 27 to rotate, and the moving gear 27 will mesh with the fixed rack 24, that is, the moving gear 27 will roll along the long side of the fixed rack 24. During the rotation, the moving gear 27 will drive the power gear 32 to rotate, and then the two clamping claws 36 will repeat the clamping and loosening actions, and in this process, the cable core will be driven to move during the clamping process. The clamping claws 36 work together to make the cable core be inserted into the cable skin section by section. During this process, after one end of the cable core leaves the auxiliary roller 19 and the two positioning rollers 21, the other end has been inserted into the cable skin, and at this time, the cable core will still not move.

[0067] One end of the cable core close to the positioning gear ring 42 will be coated with lubricating oil and rotated under the action of two coating rollers 47, and the cable skin will rotate in the opposite direction driven by the positioning gear ring 42, that is, the cable skin and the cable core will turn in opposite directions when they are matched, which is more conducive to the completion of the threading work.

[0068] A method for using a shifter cable oiling and threading machine, comprising the above-mentioned shifter cable oiling and threading machine, characterized in that it also includes the following method of use:

[0069] S1: The operator should first fix one end of the cable skin on the outside of the positioning gear ring 42 through the clamping hoop 45, and then the positioning gear ring 42 rotates to drive the cable skin to rotate;

[0070] S2: The operator then places one end of the cable core at the clamping mechanism 11 and the other end at a driving progressive mechanism 26 closest to the positioning gear ring 42. At this time, the cable core maintains the initial positioning to ensure that the cable core does not move when inserted into the cable skin in the initial stage;

[0071] S3: Finally, the operator starts the driving motor 2. When the driving motor 2 is started, it will drive the moving rack 23 to move back and forth. When the moving rack 23 moves, it will drive the moving gear 27 to rotate. When the moving gear 27 rolls along the fixed rack 24, it will drive the cable core to move toward the cable skin in sections. The oiling mechanism 46 can drive the cable core to rotate while applying lubricating oil on the outside of the cable core to promote the coordination between the cable core and the cable skin. Finally, the cable core will be completely inserted into the cable skin.

[0072] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
