Description

Technical Field

[0001] This invention relates to the field of wire processing technology, and in particular to an automatic opening and closing cradle clamping device. Background Technology

[0002] In the manufacturing and processing of wires and cables, enameled wires, and other wire materials, the winding reel serves as a key load-bearing tool for winding and transferring wires. The reliability and ease of operation of clamping and fixing the winding reel directly affect the processing efficiency, finished product quality, and labor costs of the entire production line. Currently, most commonly used winding reel clamping devices are based on traditional cradle-type structures, and their clamping process is highly dependent on manual intervention. That is, the operator must first place the winding reel in the designated receiving position by hoisting or manually carrying it, and then use manual operations such as tightening bolts and turning the clamping handle to drive the clamping mechanism to lock the winding reel. After the winding reel is processed, the unlocking step must be manually reversed to remove the reel, resulting in low processing efficiency and high labor input.

[0003] Therefore, there is an urgent need for an automatic cradle clamping device that can effectively replace manual clamping and release of the winding reel. Summary of the Invention

[0004] The purpose of this invention is to provide an automatically opening and closing cradle clamping device to solve the problems existing in the prior art.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 5This invention provides an automatically opening and closing cradle clamping device, comprising a base plate 1, with support plates 11 fixedly connected to both ends of the base plate 1. An adjustment component is provided between the two support plates 11, which operates according to the weight of the cable wound on the winding reel 5. Below the adjustment component is a limiting component that restricts the operation of the adjustment component when the weight of the cable wound on the winding reel 5 reaches a set weight. The adjustment component includes symmetrically arranged lifting parts, and clamping parts are provided on opposite sides of the two lifting parts. The clamping parts are used to clamp the winding reel, and the lifting parts are used to drive the clamping parts to rise and fall. The limiting component is used to limit the descent height of the two lifting parts and the distance between the two clamping parts. A damper is provided inside the lifting part for driving the clamping parts to rise.

[0021] This invention uses a clamping part to clamp the winding reel 5, and a lifting part lowers the clamping part as the weight of the cable on the winding reel 5 increases. When the weight of the cable reaches the weight of the limiting component, the limiting component limits the height of the lowering part and the distance between the two clamping parts, so that the two clamping parts can effectively clamp the winding reel 5. After the winding reel 5 with the cable wound is removed, the clamping part rises and resets under the action of the damper. After the clamping part resets, the next winding reel 5 can be wound with cable. This invention can effectively replace manual clamping and releasing of the winding reel 5, which not only improves processing efficiency but also effectively reduces the input of manpower.

[0022] In a further optimized design, the lifting unit includes a first connecting block 12 fixedly connected to the support plate 11. A first connecting plate 21 is fixedly connected to the side of the first connecting block 12 away from the support plate 11. A slide rail 22 is fixedly connected to the side of the first connecting plate 21 away from the first connecting block 12. A slider 23 is slidably connected to the slide rail 22. A second connecting block 24 is fixedly connected to the slider 23.

[0023] Slider 23 moves up and down along slide rail 22, and slider 23 drives second connecting block 24 to move up and down.

[0024] In a further optimized design, the first connecting block 12 is inclined on the side facing the first connecting plate 21. Through the inclined surfaces of the two first connecting blocks 12, the distance between the two second connecting blocks 24 decreases as the slider 23 descends, and increases as the slider 23 ascends.

[0025] To facilitate the installation of the damper, a top plate and a bottom plate are fixedly connected to the top and bottom surfaces of the first connecting block 12, respectively. The fixed end of the damper is installed on the bottom plate, and the telescopic end of the damper is connected to the end of the second connecting block 24 facing the bottom plate. A spring is fitted on the damper, and the two ends of the spring abut against the second connecting block 24 and the bottom plate, respectively.

[0026] The damper allows slider 23 to rise.

[0027] The damper can utilize its own damping characteristics to provide a smooth buffer for the lifting and sliding of the second connecting block 24, effectively reducing the impact speed caused by gravity when the winding reel 5 is placed, so that the slider 23 can move slowly and smoothly along the slide rail 22. It can effectively prevent the shaft seat 25 from sliding quickly, causing the limiting post 26 and the clamping plate 2 to cause a hard impact on the winding reel 5, thus protecting the edge of the winding reel 5 from damage and reducing the impact wear of various components.

[0028] Meanwhile, the damping effect enables the clamping action of the limiting post 26 and the clamping plate 2 to proceed slowly and at a uniform speed, ensuring that the winding reel 5 is subjected to balanced force, improving clamping stability, and preventing the winding reel 5 from shifting due to excessively fast action. In addition, the damper can also work with the spring to slowly reset when the winding reel 5 is removed, preventing vibration of each component due to excessively fast elastic reset, ensuring the smooth operation of each component, further adapting to the continuous and precise operation requirements of automated production lines, and effectively extending the service life of each component.

[0029] The scheme is further optimized. The clamping part includes a shaft seat 25 that is fixedly connected to the second connecting block 24. A limit post 26 is installed at one end of the shaft seat 25 away from the second connecting block 24, and a clamping plate 2 is sleeved on the limit post 26.

[0030] The limiting post 26 is coaxially arranged with the winding reel 5, so that the winding reel 5 can be stably positioned between the two limiting posts.

[0031] The design was further optimized so that the clamping plate 2 and the support plate 11 are set parallel to each other.

[0032] The design is further optimized so that the central axis of clamp 2 and the central axis of limiting post 26 are on the same central axis. Clamp 2 can effectively increase the contact area with the winding reel 5, so that the winding reel 5 can be stably positioned between the two clamps 2.

[0033] In a further optimized design, the side of the bearing seat 25 facing away from the second connecting block 24 is inclined. The inclined surface of the bearing seat 25 ensures that the clamping plate 2 and the support plate 11 remain parallel.

[0034] The scheme is further optimized. The limiting component includes symmetrically arranged support plates 33. The top surface of the support plates 33 is fixedly connected to the bottom surface of the first connecting plate 21. The support plates 33 and the support plate 11 are arranged parallel to each other. A support shaft 4 is symmetrically arranged between the two support plates 33. The support shaft 4 is located below the support plates 33 and is arranged parallel to the base plate 1.

[0035] This ensures that the position of the support plate 33 remains effectively unchanged.

[0036] In a further optimized design, side plates 34 are fixedly connected to both ends of the support plate 33. A groove 35 is provided on the end of the side plate 34 away from the support plate 33. The two ends of the support shaft 4 are slidably connected to two opposite grooves 35. Two second connecting plates 41 are fixedly connected to the support shaft 4. The two second connecting plates 41 are arranged between the two opposite side plates 34. A support rod 42 is fixedly connected to the end of the two second connecting plates 41 away from the support shaft 4.

[0037] The position of the support rod 42 after reset is above the support shaft 4.

[0038] When the winding reel 5 comes into contact with the support rod 42, as the weight of the winding reel 5 increases, the support rod 42 drives the support shaft 4 to descend along the slide groove 35, and at the same time, it can also drive the support shaft 4 to rotate.

[0039] In a further optimized design, one end of the support shaft 4 extending out of the two sliding grooves 35 is slidably connected to a ring 31. The ring 31 is fixedly connected to the second connecting block 24 via a guide rod 3. The ring 31 is threaded with a pin 32. One end of the pin 32 extending into the ring 31 is slidably connected to a groove 43. The groove 43 is formed on the support shaft 4.

[0040] As the weight of the winding reel 5 increases, the pin 32 moves along the inclined groove 43. When the pin 32 abuts against one end of the inclined groove 43, the weight of the cable on the winding reel 5 reaches the required weight.

[0041] A positioning post 13 runs through the center of the substrate 1. The positioning post 13 is fixedly connected to the substrate 1. The positioning post 13 facilitates the robot arm end effector to grasp the positioning post 13.

[0042] Positioning column 13 provides precise positioning for robotic arm grasping, adapts to automated production, improves grasping efficiency and accuracy, reduces human intervention, and helps the production line operate intelligently.

[0043] Work process: Standby state: The support rod 42 does not bear any load, so that the position of the support rod 42 is higher than the position of the support shaft 4. At the same time, under the action of the damper, the slider 23 abuts against the top plate of the first connecting plate 21, so that the distance between the two limiting posts 26 is at the maximum distance.

[0044] Receiving and clamping: After the winding reel 5 is moved above the two support rods 42, during the process of the winding reel 5 falling, since the bottom of the winding reel 5 abuts against the two support rods 42, the support rods 42 drive the support shaft 4 to descend along the slide groove 35 and rotate the support shaft 4, thereby reducing the distance between the two limiting posts 26. At the same time, the limiting posts 26 are inserted into the shaft hole of the winding reel 5 to limit and clamp the winding reel 5.

[0045] Cable winding: After the winding reel 5 is clamped, the swaying of the winding reel 5 is restricted by the limiting post 26 and the clamping plate 2, and the cable winding work can be carried out. During the winding process, as the weight of the cable is added to the winding reel 5, as the weight of the winding reel 5 gradually increases, the support rod 42 continues to drive the support shaft 4 to descend along the slide groove 35 and drive the support shaft 4 to rotate, and the distance between the two limiting posts 26 and the distance between the two clamping plates 2 continues to decrease. When the pin abuts against one end of the inclined groove 43, that is, the weight of the cable on the winding reel 5 reaches the required weight, at this time, the two clamping plates 2 can stably clamp the winding reel 5.

[0046] Reset and standby: When the winding reel 5 with the cable wound is removed, the damper and spring reset, causing the pin to move to the other end of the inclined groove 43. At the same time, the slider 23 moves to the top plate of the first connecting plate 21, and the distance between the two clamping plates 2 and the two limiting posts 26 increases, so that the winding reel 5 with the cable wound can be effectively separated from the limiting posts 26. All components return to the standby state, and the next winding reel 5 can be operated.
