Description

Technical Field

[0001] This utility model relates to the field of threading technology, and in particular to a threading and guiding mechanism for the lower wire wall. Background Technology

[0002] A threading and guiding mechanism is a device used to guide and pass slender materials such as silk threads through specific positions or components. It consists of multiple components working together to achieve precise and stable threading and guiding functions. It is used in winding and warping processes in the textile industry, wire conduit insertion and fiber optic cabling in the electronics industry, and electrical discharge wire cutting in the machining field. Wherever there is a need for precise threading and guiding of slender materials such as silk threads, wires, and optical fibers, a threading and guiding mechanism is indispensable.

[0003] A search revealed Chinese patent publication number CN222242996U, which discloses a wire threading guide mechanism, comprising a wire threading fixing guide block, a wire threading movable block movable in the left-right direction, a guide nozzle mounting plate, and a metal wire guide nozzle; a wire groove is formed on the left side wall of the wire threading fixing guide block, extending smoothly from top to bottom and then from front to back; the wire threading movable block is installed on the left side of the wire threading fixing guide block; the wire threading movable block abuts against the wire threading fixing guide block to close the wire groove; the guide nozzle mounting plate is located on top of the wire threading fixing guide block and the wire threading movable block. The lower guide nozzle of the metal wire is fixedly mounted on the guide nozzle mounting plate. A metal wire insertion hole is opened on the lower guide nozzle, which is connected to the wire groove. The wire groove of this utility model has a smooth transition, which makes the inserted and conveyed metal wire pass very smoothly, resulting in high wire threading efficiency, stable and reliable wire threading effect, saving time and effort, and reducing labor costs. However, the wire guiding mechanism can only adapt to electrode wires of specific thicknesses. In complex processing conditions, if multiple electrode wires of different specifications need to be used for processing, multiple wire guiding devices need to be prepared for replacement, which is more cumbersome and reduces work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a lower wire threading and guiding mechanism, including a lower limit fixing cylinder 1, which serves to fix and support the wire. A feeding cylinder 3 is fixedly connected to the right side of the top wall of the lower limit fixing cylinder 1. A fixing limiting plate 4 is fixedly connected to the output end of the feeding cylinder 3. The feeding cylinder 3 is used to drive the fixing limiting plate 4 to move. A guide rail 5 is fixedly connected to the left side of the top wall of the lower limit fixing cylinder 1. A slider 6 is fixedly connected to the left side of the outer wall of the fixing limiting plate 4. The slider 6 is slidably connected to the guide rail 5. The slider 6 slides on the guide rail 5 to prevent it from deviating during movement, ensuring the stability and accuracy of the movement. A guide rail limiting plate 8 is fixedly connected to the top wall of the guide rail 5. The guide rail limiting plate 8 is used to limit the movement range of the slider 6, preventing the slider 6 from detaching from the guide rail 5, thus providing safety protection. The function of the fixed limiting plate 4 is that the front and rear ends of the left side of the fixed limiting plate 4 are fixedly connected to the rack 9. The top left side of the lower limiting fixed cylinder 1 is fixedly connected to the fixed plate 7. The front and rear ends of the left side of the fixed plate 7 are rotatably connected to the rotating shaft 10. One end of the rotating shaft 10 is fixedly connected to the guide rod 12. The guide rod 12 is used to improve the accuracy and success rate of threading and reduce the deviation or tangling of the thread. The other end of the rotating shaft 10 is fixedly connected to the gear 11. The gear 11 drives the rotating shaft 10 to rotate. The gear 11 meshes with the rack 9. The rack 9 drives the gear 11 to rotate. The left side of the fixed plate 7 is fixedly connected to the fixed plate 2. The bottom of the fixed plate 2 is provided with the transmission mechanism 2. The transmission mechanism 2 is used to transmit the guide wire. The upper and lower ends of the right side of the top material cylinder 3 are both equipped with air vents 14. The air vents 14 provide power to the top material cylinder 3.

[0023] Specifically, the top-feeding cylinder 3 drives the fixed limiting plate 4 to move, and the slider 6 on its left side slides on the guide rail 5. The guide rail limiting plate 8 restricts the movement range of the slider 6 to prevent it from falling out. At the same time, the rack 9 on the left side of the fixed limiting plate 4 drives the gear 11 to rotate. The gear 11 drives the rotating shaft 10 to rotate, causing the guide rod 12 to rotate accordingly. This controls the extension and retraction of the top-feeding cylinder 3, which can precisely control the movement distance of the fixed limiting plate 4 and the rack 9, and accurately adjust the rotation angle of the guide rod 12 to meet different wire threading and guiding needs. The bottom of the fixed plate 2 13 is equipped with a transmission mechanism 2, which is used to transmit the guide wire. The air vent 14 provides power to the top-feeding cylinder 3.

[0024] Reference Figure 1 and Figure 4The transmission mechanism 2 includes a servo motor 201 and a magnetoelectric synchronous belt 203. The servo motor 201 is fixedly connected to the rear left end of the outer wall of the second fixed plate 13. A precision synchronous pulley 204 is fixedly connected to the output end of the servo motor 201, and the servo motor 201 drives the precision synchronous pulley 204 to rotate. A rotating shaft 202 is fixedly connected to the front right end of the outer wall of the second fixed plate 13. The outer wall of the rotating shaft 202 is rotatably connected to the precision synchronous pulley 204. The two precision synchronous pulleys 204 are connected by the magnetoelectric synchronous belt 203, and the magnetoelectric synchronous belt 203 drives the two precision synchronous pulleys. The wheel 204 rotates simultaneously. The outer right side of the magneto-electric synchronous belt 203 is fixedly connected to the fixing block 205. The top wall of the fixing block 205 is fixedly connected to the electromagnetic clamp 206. The electromagnetic clamp 206 grips and releases the precision guide rail 207. The inner wall of the electromagnetic clamp 206 is fixedly connected to the precision guide rail 207. The precision guide rail 207 is used to improve the accuracy and stability of transmission. The top wall of the servo motor 201 is fixedly connected to the threaded connector 15. The threaded connector 15 is used to securely connect the power line or control line to the servo motor 201 to ensure stable power transmission.

[0025] Specifically, the servo motor 201 drives the precision synchronous wheel 204 to rotate. The two precision synchronous wheels 204 are driven by the magneto-electric synchronous belt 203 and rotate on the shaft 202 of the fixed plate 213. The magneto-electric synchronous belt 203 drives the fixed block 205 and the top electromagnetic clamp 206 to move. The precision guide rail 207 on the electromagnetic clamp 206 ensures that it moves in a straight line along the preset path, reduces deviation and shaking, and improves transmission accuracy and stability. The threaded connector 15 is used to firmly connect the power line or control line to the servo motor 201 to ensure that the power can be transmitted stably.

[0026] Working principle: When the top material cylinder 3 is started, the top material cylinder 3 drives the fixed limit plate 4 to move. The slider 6 on the left side of the fixed limit plate 4 slides on the guide rail 5. The top guide rail limit plate 8 restricts the movement range of the slider 6 to prevent the slider 6 from falling off the guide rail 5. At the same time, the rack 9 on the left side of the fixed limit plate 4 drives the gear 11 to rotate. The gear 11 drives the rotating shaft 10 to rotate. The guide rod 12 is fixed at the other end of the rotating shaft 10, so the rotating shaft 10 will cause the guide rod 12 to rotate as well. By controlling the extension and retraction of the top material cylinder 3, the movement distance of the fixed limit plate 4 can be precisely controlled, thereby controlling the movement distance of the rack 9, and finally achieving precise control of the rotation angle of the guide rod 12 to meet different wire threading and guiding requirements.

[0027] The servo motor 201 drives the precision synchronous wheel 204 to rotate. The two precision synchronous wheels 204 rotate on the shaft 202 of the fixed plate 213 through the transmission of the magneto-electric synchronous belt 203. The magneto-electric synchronous belt 203 drives the fixed block 205 on it to move. Since there is an electromagnetic clamp 206 on the top of the fixed block 205, the electromagnetic clamp 206 will also move. During the movement of the electromagnetic clamp 206, the electromagnetic clamp 206 can ensure that the precision guide rail 207 moves in a straight line along the preset path, reducing deviation and shaking during the movement process, and improving the accuracy and stability of transmission.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
