Description

Technical Field

[0001] The present invention relates to the technical field of transmission machinery, and in particular to a self-positioning drag chain structure for storing data cables. Background Art

[0002] Drag chains are suitable for reciprocating motion situations and are widely used in CNC machine tools, robotic arms, construction machinery, automobiles, automated warehouses, robots and other fields. They can pull and protect built-in data lines (cables, air pipes, medium pipes), etc.

[0003] In the prior art, a Chinese patent document with publication number CN112128470B proposes a device for positioning and preventing long drag chains from sagging, comprising: a walking device, a mounting base, a support rod assembly, a limit rod, a connecting rod, a drag chain and an intelligent controller. Although a plurality of support rod assemblies are installed on the mounting base in equidistant order from front to back, and the tops of the plurality of support rod assemblies are connected in series through a connecting rod, the drag chain bracket is automatically increased or decreased as the length of the drag chain changes; one end of the limit rod is rotatably installed on the connecting rod, and the limit groove of the limit rod is located directly above the drag chain. The limit rod can limit the deviation of the drag chain in the left and right directions. When the drag chain head passes through the limit rod, the contact rod drives the rotating table to rotate, so that the convex rod rotates to the bottom of the limit rod, and the limit rod is lifted up, thereby facilitating the movement of the drag chain, and preventing "deviation" without affecting the movement of the drag chain. Although this technology is innovative compared to traditional methods, the two still maintain similarities in the installation and application of drag chains: drag chains are also suitable for vertical, horizontal or inclined installation environments, but when the drag chain needs to perform S-shaped rotational motion, especially when the moving end is close to the end of the stroke, a common problem emerges - due to the bidirectional bending structure design of the drag chain, the upper drag chain is prone to drooping, which not only leads to accumulation and mutual interference between the drag chains, but also intensifies the friction between the drag chains, seriously hindering the running speed of the drag chain. What is more unfavorable is that when the drag chain rotates in the opposite direction, this drooping phenomenon will also intensify the interference and friction, making high-speed operation impractical. In addition, the drooping of the drag chain will also cause a certain degree of wear on the data line tube carried inside it, thereby weakening its protection efficiency for the data line tube.

[0004] Furthermore, we disclose a self-positioning drag chain structure for storing data cables to meet the actual demand for the existing technology that the drag chain is prone to collapse when performing S-shaped rotation operation. Summary of the invention

[0017] The self-positioning drag chain structure for data cable storage is provided with a limited guide assembly, which effectively solves the problems of collapse, accumulation and interference that are easy to occur in traditional drag chains during S-shaped rotation. Through the dual guide structure of the automatic support and limit snap assembly and the arc guide plate composed of a limit ring, a limit rod, a limit groove, a limit spring, a fixed seat, a limit spring block, etc., the drag chain can always maintain a stable state during the rotation process. The limit spring design in the automatic support and limit snap assembly enables the support end to automatically compress downward to avoid when subjected to force, thereby avoiding friction and interference between the drag chains. At the same time, the existence of the arc guide plate further ensures that the drag chain can be smoothly pushed to the outside of the automatic support and limit snap assembly, thereby achieving effective support and limitation.

When the drag chain is in operation, the lubricating oil can be evenly and accurately applied to various joints of the drag chain, thereby effectively reducing the friction resistance of the drag chain during operation. This not only improves the operating efficiency of the drag chain, but also reduces the heat and noise generated by friction. At the same time, regular application of lubricating oil can also maintain the drag chain and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0036] like Figures 1 to 12 As shown, a self-positioning drag chain structure for storing data cables comprises an installation fixing plate 1, the outer side of the upper end surface of the installation fixing plate 1 is fixedly connected to a limited support ring 2, the middle part of one side end surface of the installation fixing plate 1 is rotatably connected to a fixing ring 35, the outer wall of the fixing ring 35 is fixedly bolted to a drag chain body 5, the other end of the drag chain body 5 is bolted to the inner wall of the limited support ring 2, the middle part of the lower end surface of the installation fixing plate 1 is bolted to a bearing seat 11, the interior of the bearing seat 11 is provided with a supporting fixed shaft 10 fixedly connected to the output end of the servo motor, the middle part of the supporting fixed shaft 10 is fixedly connected to the fixing ring 35 and penetrates the fixing ring 35, a limited guide assembly is installed on the installation fixing plate 1, the limited guide assembly is used to guide and position the drag chain when performing S-shaped rotation operation, the upper end of the limited support ring 2 is fixedly connected to a top plate 3, the middle part of the top plate 3 is provided with a liquid adding assembly, the liquid adding assembly is used to apply lubricating oil to the joints on the drag chain body 5, and the liquid adding assembly is driven by the forward rotation of the supporting fixed shaft 10;

[0037] The self-positioning drag chain structure for storing data cables significantly improves its performance through the design of the limit guide component and the liquid adding component. The limit guide component ensures that the drag chain can be automatically positioned and supported when performing S-shaped rotation operation, effectively avoiding the problems of the drag chain collapsing, accumulation and interference, and ensuring the smooth operation of the drag chain. At the same time, the liquid adding component uses the rotation drive of the support fixed shaft 10 to apply lubricating oil to the joints on the drag chain body 5, further reducing friction and extending the service life of the drag chain.

[0038] Further, such as Figures 1 to 5 , Figure 7 , Figure 8 , Fig.11As shown, the limiting guide assembly includes a limiting semi-ring 8 fixedly connected to the outer side of the middle part of the upper end surface of the mounting fixing plate 1, and both ends of the limiting semi-ring 8 are inclined outward. A mounting rod 9 is fixedly connected to one side of the drag chain body 5 and the fixing ring 35 bolted together, and an arc-shaped guide plate 7 is fixedly connected to the upper end of one side of the mounting rod 9. Both ends of the arc-shaped guide plate 7 are rounded. The limiting guide assembly also includes a limiting circular ring 12 fixedly connected to the lower end surface of the mounting fixing plate 1, and a plurality of open grooves 36 are evenly spaced at the lower end of the limiting circular ring 12. A fixing seat 16 is fixedly connected to each of the plurality of open grooves 36, and the lower end of the fixing seat 16 is rotated A limit rod 13 is dynamically connected, and a positioning column 18 is fixedly connected to one side of the upper end surface of the limit rod 13. A limit spring 15 is sleeved on the outside of the positioning column 18. The upper end of the limit spring 15 is fixedly connected to the mounting plate 1. A limit spring block 17 is fixedly connected to the side of the upper end surface of the limit rod 13 away from the positioning column 18. The upper end of the limit spring block 17 is arc-shaped and has rounded corners. A plurality of limit grooves 14 are evenly spaced apart on the outside of the middle part of the mounting plate 1. The limit spring block 17 is located inside the limit groove 14 and the upper end of the limit spring block 17 extends into the interior of the limit support ring 2 when the limit spring 15 is in an uncompressed state.

[0039] First, when the drag chain body 5 starts to run, the servo motor connected to the supporting fixed shaft 10 will start, and the supporting fixed shaft 10 will mobilize the fixing ring 35 to rotate. Since one end of the drag chain body 5 is bolted to the fixing ring 35, the drag chain starts to run and it will move along the set trajectory. In this process, the limiting semi-ring 8 fixedly connected to the outer side of the middle part of the upper end surface of the mounting fixing plate 1 plays a preliminary limiting role. Both ends of the limiting semi-ring 8 are inclined outward. This design allows the drag chain to be guided to a certain extent when it contacts the limiting semi-ring 8, so as to move in the correct direction and reduce friction.

[0040] As the fixing ring 35 continues to rotate, the arc-shaped guide plate 7 on one side of the mounting rod 9 on the fixing ring 35 will contact the end of the drag chain body 5. Both ends of the arc-shaped guide plate 7 are rounded. This design not only reduces the friction between the drag chain and the guide plate, but also enables the arc-shaped guide plate 7 to pass through the drag chain body 5 more smoothly during the rotation process. The arc-shaped guide plate 7 can further support the drag chain and prevent it from collapsing.

[0041] At the same time, the limiting ring 12 located on the lower end surface of the mounting plate 1 and the limiting rod 13, limiting spring block 17 and other components inside it also begin to play a role. When the towline moves near the limiting ring 12, it will contact the upper end of the limiting spring block 17. Since the upper end of the limiting spring block 17 is arc-shaped and has rounded corners, the towline can pass smoothly and generate a certain interaction force with the limiting spring block 17. In this process, the limiting spring block 17 will be pushed by the towline and compress the limiting spring 15 downward. The existence of the limiting spring 15 provides a certain buffering effect for the limiting spring block 17, and also enables the limiting spring block 17 to automatically move downward when it is pushed, thereby avoiding direct collision and friction between the towline and the limiting spring block 17.

[0042] When the drag chain passes through the limit spring block 17, the restoring force of the limit spring 15 will cause the limit spring block 17 to quickly return to its original position. At this time, the upper end of the limit spring block 17 will extend into the interior of the limit support ring 2 again, providing support and limiting effect for the operation of the drag chain to prevent it from collapsing.

[0043] Further, such as Figure 1 , Figure 6 , Fig. 9 , Fig.10 , Fig.12As shown, the liquid adding assembly includes a liquid storage box 4 fixedly connected to the middle part of the upper end surface of the top plate 3, the upper end of the liquid storage box 4 is fixedly connected with a liquid injection port 19, the liquid injection port 19 is of inclined design, and the upper end of the liquid injection port 19 is threadedly connected with a sealing cover that plays a sealing role, and a delivery pipe 20 is fixedly connected to the lower end of the middle part of the end surface of one side of the liquid storage box 4, one end of the delivery pipe 20 extends into the interior of the limiting support ring 2 and is located between the fixed ring 35 and the limiting semi-ring 8 and is fixedly connected with a shunt pipe 21, and the lower end of the shunt pipe 21 is evenly spaced and fixedly connected with a plurality of bristles 22, the bristles 22 are of hollow design and are connected to the shunt pipe 21, and the lower end of the bristles 22 is in contact with the drag chain body 5, and the liquid storage box 4 The piston plate 6 is slidably connected to the inside thereof, and a waist-shaped groove 33 is provided in the middle of the end surface of one side of the piston plate 6 away from the delivery pipe 20. A card plate 34 is slidably connected to the inside of the waist-shaped groove 33, and a gear rod 24 is fixedly connected to one end surface of the card plate 34. One end of the gear rod 24 passes through the liquid storage box 4, and a sliding groove adapted to the connection between the liquid storage box 4 and the gear rod 24 is provided. A driving gear 25 is meshedly connected to one side of the outer wall of the gear rod 24, and a connecting shaft 42 is fixedly connected to the lower end of the driving gear 25. The upper end of the supporting fixed shaft 10 is transmission-connected to the pulley structure 23, and the other end of the pulley structure 23 is transmission-connected to the transmission shaft 41. The upper end of the transmission shaft 41 passes through the top plate 3 and the middle part is connected to the top plate 3 The upper end of the transmission shaft 41 is fixedly connected with a driving gear 38, and one side of the driving gear 38 is meshed with a driven gear 37. The lower end of the driven gear 37 is engaged and rotatably connected with the top plate 3. The upper end of the driven gear 37 is fixedly connected with a limiting column 29, and a ratchet groove 32 is provided inside the limiting column 29. The lower end of the connecting shaft 42 extends into the ratchet groove 32 and is fixedly connected with a connecting plate 30. The lower end of the connecting plate 30 is engaged and rotatably connected to the inside of the ratchet groove 32. The upper end of the connecting plate 30 is evenly spaced and rotatably connected with a plurality of ratchet bodies 31. The upper end of the connecting plate 30 is rotatably connected with a plurality of ratchet bodies 31, and one end of the ratchet body 31 is away from the connecting plate 30. Fitting with the inner wall of the ratchet groove 32, a torsion spring is provided at the rotation connection between the ratchet body 31 and the connecting plate 30 to reset the ratchet body 31, a mounting plate 28 is fixedly connected to one side of the upper end of one end surface of the liquid storage box 4, a card slot 27 is provided on one side of the mounting plate 28, a card rod 39 is slidably connected inside the card slot 27, a curved plate 40 is fixedly connected to one side of the lower end of the card rod 39, the curved plate 40 is curved and fits with the inner wall of the gear rod 24, a telescopic spring 26 is fixedly connected to one side of the upper end of the outer wall of the card rod 39, and the end of the telescopic spring 26 away from the card rod 39 is fixedly connected to the liquid storage box 4, the card slot 27 is L-shaped and the width of the card slot 27 is equal to the diameter of the card rod 39;

[0044] First, the liquid storage box 4 is used as a storage container for the lubricating liquid, and the lubricating liquid is added through the liquid filling port 19 at its upper end. The liquid filling port 19 is designed to be inclined to facilitate the pouring of the lubricating liquid, and the sealing cover connected by a thread ensures the sealing of the liquid storage box 4 to prevent the lubricating liquid from leaking from the bristles 22 when the liquid adding component is not working;

[0045] When the drag chain structure starts to run, the supporting fixed shaft 10 drives the pulley structure 23 to rotate, and the pulley structure 23 is connected to the driving gear 38 through the transmission shaft 41, and the driving gear 38 is meshed with the driven gear 37 for transmission. This series of transmission mechanisms enables the limit column 29 at the upper end of the driven gear 37 to rotate accordingly;

[0046] The ratchet groove 32 opened inside the limit column 29 cooperates with the connecting plate 30 at the lower end of the connecting shaft 42 and the ratchet body 31 rotating on the connecting plate 30 to form a one-way transmission mechanism. When the limit column 29 rotates, the ratchet body 31 will slide in the ratchet groove 32 and be affected by the reset force of the torsion spring, ensuring that the ratchet body 31 always fits with the inner wall of the ratchet groove 32, thereby realizing one-way transmission. This design enables the liquid adding component to work normally when the drag chain structure is running in the forward direction; while when it is running in the reverse direction, the liquid adding action will not be triggered, avoiding unnecessary waste of lubricating fluid;

[0047] As the limiting column 29 rotates forward, the connecting shaft 42 rotates synchronously through the one-way transmission mechanism, and the rotation of the connecting shaft 42 drives the driving gear 25 to rotate. The driving gear 25 is meshed and connected with the gear rod 24, and then the rotation of the driving gear 25 further drives the piston plate 6 inside the liquid storage box 4 to move. The sliding of the piston plate 6 in the liquid storage box 4 changes the size of the space inside the liquid storage box 4, thereby generating pressure. When the piston plate 6 moves toward the delivery pipe 20, the lubricating liquid inside the liquid storage box 4 is pressed Into the delivery pipe 20, one end of the delivery pipe 20 extends into the interior of the limit support ring 2, is located between the fixing ring 35 and the limit semi-ring 8, and is fixedly connected with a shunt pipe 21, and the lower end of the shunt pipe 21 is evenly and fixedly connected with a plurality of hollow bristles 22, and the bristles 22 are connected with the shunt pipe 21. Therefore, when the lubricating liquid in the delivery pipe 20 is squeezed out, it will enter the inside of the bristles 22 along the shunt pipe 21, and contact with the drag chain body 5 through the lower end of the bristles 22, so as to realize automatic lubrication of the drag chain body 5;

[0048] In addition, the liquid adding assembly is also designed with components such as a clamping rod 39 and an arc plate 40 for controlling and adjusting the movement of the gear rod 24. The clamping rod 39 is fixedly connected to the liquid storage box 4 through the telescopic spring 26 and can slide in the card slot 27. Under normal circumstances, the clamping rod 39 is limited at one end of the card slot 27 by the pulling force of the telescopic spring 26. At this time, the arc plate 40 is tightly fitted with the inner wall of the gear rod 24, so that when the driving gear 25 rotates, the gear rod 24 can move forward smoothly, driving the piston plate 6 to move in the liquid storage box 4 to complete the liquid delivery work. When there is no lubricating oil in the liquid storage box 4 and liquid needs to be added, first open the sealing cover at the upper end of the liquid filling port 19 by rotating it, and then pull the clamping rod 39 so that the clamping rod 39 is located at the other end of the card slot 27. At this time, the arc plate 40 does not contact the outer wall of the gear rod 24, and the gear rod 24 is pulled to one side to disengage the gear rod 24 from the driving gear 25. The gear rod 24 is meshed and connected, and the gear rod 24 is pulled backward to make the piston plate 6 move backward in the liquid storage box 4. The stability of the gear rod 24 can be maintained by the waist groove 33 and the clamping plate 34. At this time, liquid can be injected into the liquid storage box 4 through the liquid filling port 19. In actual use, the sealing container is threadedly connected to the upper end of the liquid filling port 19, and liquid is injected into the liquid storage box 4 through the sealing container, which can avoid lubricating oil from the delivery pipe 20 to the bristles 22 as much as possible. Alternatively, during the production process of the device, the delivery pipe 20 is set to an arc shape, and the top of the arc is higher than the liquid storage box 4. After completing the liquid injection work, the upper end of the liquid filling port 19 is sealed by the sealing cover, and the clamping rod 39 is pulled to release the telescopic spring 26, driving the arc plate 40 to contact the outer wall of the gear rod 24, and limiting the range of motion of the gear rod 24. At this time, the gear rod 24 is re-engaged and connected with the driving gear 25 to continue to complete the lubrication work of the drag chain.

[0049] In summary, the liquid adding component realizes the automatic lubrication function of the drag chain body 5 through the precise transmission mechanism and lubrication structure. This design not only improves the operating stability and service life of the drag chain structure, but also reduces the cost and time of manual maintenance.
