Abstract
Description
Technical Field
[0001] This application relates to the field of yarn twisting devices, and more particularly to a wheel speed sensor yarn twisting device. Background Technology
[0002] Currently, the connecting wires of wheel speed sensors are usually rope-like cables made of several or several groups of wires (at least two wires in each group) twisted together. The copper wires are mostly made of copper, and each group of wires is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. A wire stripper is used to strip the cable to a specified length. When the cable is stripped, the individual copper wires may become scattered. Since the cable usually needs to be soldered to the circuit board, the scattered copper wires may cause poor soldering. Therefore, a wire twisting device is used to twist the copper guide wires together.
[0003] Existing thread twisting devices typically twist thread by moving two thread twisting plates relative to each other. Usually, the bottom thread twisting plate is fixed while the top thread twisting plate moves back and forth. Workers need to manually control the up and down movement of the top thread twisting plate to better twist the thread, which increases the workload of workers. In addition, because different models of wheel speed sensors use different models of connecting wires, different models of fixing devices are also required to fix the wires. Utility Model Content
[0004] To address the problem of workers needing to manually control the up-and-down movement of the top yarn-twisting plate, which increases their workload, this application provides a wheel speed sensor yarn-twisting device.
[0005] The wheel speed sensor yarn twisting device provided in this application adopts the following technical solution: it includes a base, a lower yarn twisting plate is fixed on one side of the top of the base, a support rod is fixed in the middle of the side of the base near the lower yarn twisting plate, a top plate is fixed on the top of one side of the support rod, an electromagnet is fixed at the bottom of the top plate, a second servo motor is fixed to one end of the base through a first connecting rod, a transmission rod is fixed to the power output end of the second servo motor, a slide rod is fixed to the top of one end of the transmission rod, an upper yarn twisting plate is movably installed on the top of the lower yarn twisting plate, a magnet is fixed to the top of the upper yarn twisting plate, a guide rail is fixed to one end of the magnet through a second connecting rod, a first switch and a second switch are fixed to the top of both ends of the lower yarn twisting plate respectively, and a clamping mechanism is fixed to the other side of the base.
[0006] By adopting the above technical solution, when the upper thread-rolling plate touches the first switch, the electromagnet is energized, causing the upper thread-rolling plate and the lower thread-rolling plate to fit tightly together. At the same time, the upper thread-rolling plate moves laterally to roll the thread. When the upper thread-rolling plate touches the second switch, the electromagnet is de-energized, and the magnet of the upper thread-rolling plate is attracted to the bottom of the top plate.
[0007] Preferably, the guide rail and the slide rod are movably sleeved together, the height of the slide rod is greater than the height of the guide rail, the upper and lower thread-rolling plates are laterally slidably connected, and the upper and lower thread-rolling plates are movably sleeved together.
[0008] By adopting the above technical solution, the transmission rod is driven to rotate by the second servo motor, which in turn drives the slide rod to rotate inside the guide rail. The guide rail and the slide rod work together to convert the circular motion of the slide rod into the reciprocating left and right movement of the upper thread-rolling plate. The lower thread-rolling plate limits the upper thread-rolling plate, so that the upper thread-rolling plate can only move left and right and up and down.
[0009] Preferably, rollers are fixed on both sides of the bottom of the top plate, and multiple rollers are arranged horizontally at equal intervals. The horizontal height of the bottom of the rollers is less than the horizontal height of the bottom of the electromagnet.
[0010] By adopting the above technical solution, the magnet is repelled by the electromagnet when it is energized, so that the magnet and the upper and lower warping plates can fit tightly together. When the electromagnet is de-energized, the magnet is attracted to the top plate. The attracted magnet touches the roller, allowing the magnet to slide under the top plate.
[0011] Preferably, both the first switch and the second switch are electrically connected to the electromagnet. The first switch is used to control the electromagnet to be energized, and the second switch is used to control the electromagnet to be de-energized. The electromagnet and the magnet are used together.
[0012] By adopting the above technical solution, when the upper thread-rolling plate moves back and forth, the electromagnet is energized when the upper thread-rolling plate touches the first switch, so that the upper thread-rolling plate and the lower thread-rolling plate are tightly attached. At the same time, the upper thread-rolling plate moves laterally to roll the thread. When the upper thread-rolling plate touches the second switch, the electromagnet is de-energized, and the magnet of the upper thread-rolling plate is attracted to the bottom of the top plate.
[0013] Preferably, the clamping mechanism includes a first servo motor, which is fixed to one end of the base. The top of the base has a sliding groove, and a threaded rod is fixed to the power output end of the first servo motor. The threaded rod moves through the inside of the sliding groove.
[0014] By adopting the above technical solution, the first servo motor rotates to drive the threaded rod to rotate, which in turn drives the slider to slide in the groove.
[0015] Preferably, sliders are slidably connected to both sides of the middle part of the inner wall of the groove, and both sliders are threadedly connected to the threaded rod, with the thread directions of the two sliders being opposite.
[0016] By adopting the above technical solution, when the threaded rod rotates, the two sliders can simultaneously move towards the middle or separate towards both ends.
[0017] Preferably, each of the two sliders has a pressing block fixed to its top, the two pressing blocks are arranged in an arc shape on opposite sides, and the top of each of the two pressing blocks has grooves that are equidistant from each other in both horizontal and vertical directions, and the two sets of grooves are arranged in an interlaced manner.
[0018] By adopting the above technical solution, the wire is placed in the arc-shaped groove of the two extrusion blocks, and then the first servo motor is controlled to rotate, so that the two extrusion blocks move towards the center at the same time to clamp the wire. The grooves make the wire squeezed more tightly, preventing the wire from rotating along with the upper wire rolling plate.
[0019] In summary, this application includes at least the following beneficial technical effects:
[0020] 1. This application uses a second servo motor to drive the upper thread-rolling plate to move back and forth. When the upper thread-rolling plate touches the first switch, the electromagnet is energized, causing the upper thread-rolling plate to fit tightly with the lower thread-rolling plate. At the same time, the upper thread-rolling plate moves laterally to roll the thread. When the upper thread-rolling plate touches the second switch, the electromagnet is de-energized, and the magnet of the upper thread-rolling plate is attracted to the bottom of the top plate. The attracted magnet touches the roller, allowing the magnet to slide under the top plate. The magnet slides until it touches the first switch again to continue rolling the thread. This cycle repeats automatically to roll the thread, thereby achieving automatic control of the upper thread-rolling plate to move up and down, improving efficiency and reducing the workload of workers.
[0021] 2. This application places the wire in the arc-shaped groove of two extrusion blocks, and then controls the first servo motor to rotate, so that the two extrusion blocks move towards the center at the same time to clamp the wire. The grooves make the wire more tightly squeezed, and different types of wires can be fixed well, thus achieving the effect of fixing multiple types of wires. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0028] This application discloses a wheel speed sensor yarn twisting device, including a base 1. A lower yarn twisting plate 8 is fixed to one side of the top of the base 1. A support rod 9 is fixed to the middle of the side of the base 1 near the lower yarn twisting plate 8. A top plate 10 is fixed to the top of one side of the support rod 9. An electromagnet 12 is fixed to the bottom of the top plate 10. A second servo motor 18 is fixed to one end of the base 1 via a first connecting rod 17. A transmission rod 19 is fixed to the power output end of the second servo motor 18. A slide rod 20 is fixed to the top of one end of the transmission rod 19. An upper yarn twisting plate 13 is movably mounted on the top of the lower yarn twisting plate 8. A magnet is fixed to the top of the upper yarn twisting plate 13. Iron 14, magnet 14, has a guide rail 22 fixed at one end via a second connecting rod 21. The top of both ends of the lower wire-rolling plate 8 are respectively fixed with a first switch 15 and a second switch 16. When the upper wire-rolling plate 13 touches the first switch 15, the electromagnet 12 is energized, causing the upper wire-rolling plate 13 to fit tightly against the lower wire-rolling plate 8. At the same time, the upper wire-rolling plate 13 moves laterally to roll the wire. When the upper wire-rolling plate 13 touches the second switch 16, the electromagnet 12 is de-energized, and the magnet 14 of the upper wire-rolling plate 13 is attracted to the bottom of the top plate 10. A clamping mechanism is fixed on the other side of the base 1 to clamp the wire.
[0029] Reference Appendix Figure 2 The guide rail 22 and the slide rod 20 are movably connected. The height of the slide rod 20 is greater than the height of the guide rail 22. The upper thread rolling plate 13 and the lower thread rolling plate 8 are laterally slidably connected. The upper thread rolling plate 13 and the lower thread rolling plate 8 are movably connected. The transmission rod 19 is driven to rotate by the second servo motor 18, which in turn drives the slide rod 20 to rotate inside the guide rail 22. The guide rail 22 and the slide rod 20 work together to convert the circular motion of the slide rod 20 into the left and right reciprocating movement of the upper thread rolling plate 13. The lower thread rolling plate 8 limits the upper thread rolling plate 13, so that the upper thread rolling plate 13 can only move left and right and up and down.
[0030] Reference Appendix Figure 4The top plate 10 has rollers 11 fixed on both sides of its bottom. Multiple rollers 11 are arranged horizontally at equal intervals. The horizontal height of the bottom of the rollers 11 is less than the horizontal height of the bottom of the electromagnet 12. When the electromagnet 12 is energized, it repels the magnet 14, allowing the magnet 14 to fit tightly against the upper thread rolling plate 13 and the lower thread rolling plate 8. When the electromagnet 12 is de-energized, the magnet 14 attracts the top plate 10. After attraction, the magnet 14 touches the rollers 11, allowing the magnet 14 to slide below the top plate 10.
[0031] Reference Appendix Figure 2 The first switch 15 and the second switch 16 are both electrically connected to the electromagnet 12. The first switch 15 is used to control the electromagnet 12 to be energized, and the second switch 16 is used to control the electromagnet 12 to be de-energized. The electromagnet 12 and the magnet 14 are used together. When the upper thread-rolling plate 13 moves back and forth, when the upper thread-rolling plate 13 touches the first switch 15, the electromagnet 12 is energized, so that the upper thread-rolling plate 13 and the lower thread-rolling plate 8 are tightly attached. At the same time, the upper thread-rolling plate 13 moves laterally to roll the thread. When the upper thread-rolling plate 13 touches the second switch 16, the electromagnet 12 is de-energized, and the magnet 14 of the upper thread-rolling plate 13 is attracted to the bottom of the top plate 10.
[0032] Reference Appendix Figure 1 The clamping mechanism includes a first servo motor 3, which is fixed to one end of the base 1. A slide groove 2 is provided on the top of the base 1. A threaded rod 4 is fixed to the power output end of the first servo motor 3. The threaded rod 4 moves through the inside of the slide groove 2. The first servo motor 3 rotates to drive the threaded rod 4 to rotate, thereby driving the slider 5 to slide in the slide groove 2.
[0033] Reference Appendix Figure 1 The inner wall of the groove 2 has two sliders 5 slidably connected to each other on both sides. Both sliders 5 are threadedly connected to the threaded rod 4, and the threads of the two sliders 5 are opposite, so that when the threaded rod 4 rotates, the two sliders 5 can move towards the middle or separate towards both ends at the same time.
[0034] Reference Appendix Figure 1 The top of each of the two sliders 5 is fixed with a pressing block 6. The two pressing blocks 6 are arranged in an arc shape on opposite sides. The top of each pressing block 6 has grooves 7 that are equidistant from each other in both horizontal and vertical directions. The two sets of grooves 7 are arranged in an interlaced manner. The wire is placed in the arc groove of the two pressing blocks 6, and then the first servo motor 3 is controlled to rotate, so that the two pressing blocks 6 move towards the center at the same time to clamp the wire. The grooves 7 make the wire squeezed more tightly, preventing the wire from rotating along with the upper wire rolling plate 13.
[0035] The implementation principle of the wheel speed sensor wire twisting device in this application embodiment is as follows: First, the wire is placed in the arc-shaped grooves of two extrusion blocks 6. Then, the first servo motor 3 is controlled to rotate, so that the two extrusion blocks 6 move towards the center at the same time to clamp the wire. The groove 7 is set so that the wire can be squeezed more tightly, preventing the wire from rotating along with the upper twisting plate 13. Then, the second servo motor 18 is started, which drives the transmission rod 19 to rotate, thereby driving the slide rod 20 to rotate inside the guide rail 22. The guide rail 22 and the slide rod 20 cooperate to convert the circular motion of the slide rod 20 into the left and right reciprocating movement of the upper twisting plate 13, which is controlled by the lower twisting plate 8. The upper thread-twisting plate 13 is limited to moving only left and right and up and down. When the upper thread-twisting plate 13 moves back and forth, the electromagnet 12 is energized when the upper thread-twisting plate 13 touches the first switch 15, so that the upper thread-twisting plate 13 and the lower thread-twisting plate 8 are in close contact. At the same time, the upper thread-twisting plate 13 moves laterally to twist the thread. When the upper thread-twisting plate 13 touches the second switch 16, the electromagnet 12 is de-energized, and the magnet 14 of the upper thread-twisting plate 13 is attracted to the bottom of the top plate 10. The attracted magnet 14 touches the roller 11, so that the magnet 14 can slide under the top plate 10. It slides until it touches the first switch 15 again to continue twisting the thread. The twisting is carried out automatically in a cycle.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
