Description

Technical Field

[0001] This utility model relates to the field of cable reel manufacturing technology, specifically a quick assembly fixture for cable reels. Background Technology

[0002] Cable reels are indispensable auxiliary tools in the production, transportation, storage and use of wires and cables. They are mainly used for winding, storing and protecting wires and cables. The design of quick assembly clamps for cable reels usually revolves around modular structures, adjustable components and quick locking mechanisms to achieve efficient positioning and fixing of cable reels of different specifications. In the prior art, patent CN217494056U discloses a quick assembly fixture for cable reels, including a mounting base. A rotating base plate is rotatably mounted on the inner wall of the mounting base. A positioning pin is movably sleeved on one side of the mounting base. A limit hole is formed on the surface of the rotating base plate near the positioning pin. A guide groove is formed on the upper surface of the rotating base plate. A clamping base is slidably mounted on the rotating base plate through the guide groove. Positioning bolts are threaded on the upper surfaces of both ends of the clamping base plate. This type of quick assembly fixture for cable reels has some problems. For example, the width of the arc-shaped positioning unit is fixed. The cable reel is fixed by pressing it with positioning bolts and supporting each other with the side wall of the arc-shaped positioning unit. However, multiple positioning bolts need to be adjusted to fix the cable reel. At the same time, the position of the arc-shaped support plate is fixed and cannot be adapted to the size of the internal support of the cable reel, which limits the assembly efficiency of the cable reel.

[0015] 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.

[0016] Please see Figure 1-5 This embodiment provides a technical solution: a quick assembly fixture for cable reels, including a clamping frame 1, with two symmetrically distributed adjustable sliding frames 4 at the upper end of the clamping frame 1, and also includes a clamping mechanism 2 and a support mechanism 3; Clamping mechanism 2 includes an arc-shaped seat 21, a limiting arc plate 22, a guide groove 23, a guide plate 24, and oblique rubber strips 29. The arc-shaped seat 21 is fixedly connected to the upper end of the sliding frame 4. The front and rear ends of the inner arc surface of the arc-shaped seat 21 are provided with limiting arc plates 22. The left and right ends of the inner arc surface of the arc-shaped seat 21 are provided with guide grooves 23. The left and right ends of the outer arc surface of the limiting arc plate 22 are fixedly connected with guide plates 24. The guide plates 24 are slidably connected to the adjacent guide grooves 23. The side surface of the limiting arc plate 22 near the center of the adjacent arc-shaped seat 21 is fixedly connected with evenly distributed oblique rubber strips 29. The clamping mechanism 2 also includes a drive chamber 25, a sliding plate 26, a bidirectional screw 27, and a knob 28. The drive chamber 25 is located at the lower end of the arc-shaped seat 21. All sliding plates 26 are fixedly connected to the lower end of the limiting arc plate 22. The outer surface of each sliding plate 26 is slidably connected to the interior of the adjacent drive chamber 25. A bidirectional screw 27 is rotatably connected to the interior of each drive chamber 25. The interior of each sliding plate 26 is threadedly connected to the outer surface of the adjacent bidirectional screw 27. The end of the bidirectional screw 27 away from the center of the clamping frame 1 extends to the outer side of the adjacent drive chamber 25. (The distance between the surface of the drive chamber 25 away from the center of the clamping frame 1 and the surface of the sliding plate 26 away from the center of the clamping frame 1, the distance between the inner surfaces of two adjacent sliding plates 26 and the distance between the surface of the drive chamber 25 near the center of the clamping frame 1 and the surface of the sliding plate 26 near the center of the clamping frame 1 away from the center of the clamping frame 1...) Corrugated protective tubes can be fixedly connected between the surfaces of the two sides of the clamping frame 1. The corrugated protective tubes are all sleeved on the outer surface of the adjacent bidirectional screw 27, and the corrugated protective tubes can be extended or retracted accordingly. A knob 28 is fixedly connected to the end of the bidirectional screw 27 away from the center of the clamping frame 1. Indicating arrows 16 are provided at both ends of the upper surface of the limiting arc plate 22. Scale bars 15 are provided at both ends of the upper surface of the arc seat 21. The indicating arrows 16 are installed in conjunction with the horizontally adjacent scale bars 15. (The sliding stroke of the limiting arc plate 22 inside the corresponding arc seat 21 is limited. The sliding stroke of the limiting arc plate 22 is displayed by the scale bars 15. The scales inside the scale bars 15 that are on the same horizontal and vertical plane as the indicating arrows 16 represent the current limiting arc plate.) The position information of the two limiting arc plates 22 located inside the same arc-shaped seat 21 is combined to obtain the spacing information of the two limiting arc plates 22 located inside the same arc-shaped seat 21. The cable reel is placed inside the two arc-shaped seats 21 respectively, and then the knob 28 is rotated. The rotation of the knob 28 drives the adjacent bidirectional screw 27 to rotate. The rotation of the bidirectional screw 27 causes the two adjacent sliding plates 26 to move. The two sliding plates 26 located inside the same drive chamber 25 move towards the center of the corresponding arc-shaped seat 21, thereby causing the adjacent limiting arc plates 22 of the sliding plates 26 to move towards the center of the corresponding arc-shaped seat 21. At the same time, the guide plates 24 slide inside the adjacent guide grooves 23.The limiting arc plates 22 provide guidance and limitation for movement. As indicated by the arrow 16, the spacing between adjacent limiting arc plates 22 effectively meets the clamping requirements of the cable reel. Simultaneously, the inclined rubber strips 29 are in close contact with the surface of the cable reel. Furthermore, the inclined tearing force after the inclined rubber strips 29 contact the surface of the cable reel prevents rotation of the cable reel, thus providing stable clamping of the cable reel in real time. Support mechanism 3: Located in the middle of clamping frame 1, support mechanism 3 includes an arc-shaped support plate 31, a sliding rod 32, a sliding groove 33, and a connecting rod 34. The arc-shaped support plate 31 is located at the upper end of clamping frame 1, and the sliding rod 32 is fixedly connected to the lower end of the arc-shaped support plate 31. A sliding opening is provided at the center of clamping frame 1, and the interior of the sliding opening is slidably connected to the outer surface of the sliding rod 32. The sliding groove 33 is longitudinally symmetrically arranged in the middle of clamping frame 1. The front and rear ends of the lower surface of the arc-shaped support plate 31 are rotatably connected to the connecting rod 34. Each connecting rod 34 has a connecting shaft fixedly connected to its lower end. The connecting shafts are slidably connected to the interior of adjacent sliding grooves 33. The support mechanism 3 also includes a spring 35 and a limiting cap 36. The limiting cap 36 is located at the lower end of the sliding rod 32. A spring 35 is fixedly connected between the center of the lower surface of the clamping frame 1 and the upper surface of the limiting cap 36. (The upper pin of the spring 35 can be engaged with the lower end of the clamping frame 1 via a snap fastener, and the lower pin of the spring 35 can be engaged with the upper surface of the limiting cap 36 via a snap fastener. The limiting cap 36 is connected to the sliding rod 32.) The lower end of rod 32 is threaded. The limit cap 36 is periodically removed by screwing it out. Springs 35 are periodically replaced to prevent aging. Springs 35 are all fitted onto the outer surface of the slide rod 32. While assembling the cable reel, the components in the cable reel are placed on the upper end of the arc-shaped support plate 31. The arc-shaped support plate 31 is subjected to downward force, causing the slide rod 32 to slide downwards inside the sliding opening. The downward movement of the slide rod 32 causes the limit cap 36 to move downwards, thereby causing the spring 35 to elastically compress. The elastic force reacts to the limiting cap 36, which transmits the elastic force to the slide bar 32, and finally to the arc-shaped support plate 31. This allows the arc-shaped support plate 31 to provide stable support for the internal components of the cable reel. In conjunction with the assembly of the cable reel, the arc-shaped support plate 31 moves downward, causing the upper end of the connecting rod 34 to move downward. The downward movement of the upper end of the connecting rod 34 causes the connecting shafts at the lower end of the connecting rod 34 to slide within the corresponding slide grooves 33. The connecting shafts move away from the center of the clamping frame 1 within the corresponding slide grooves 33. Wherein: the left end of the clamping frame 1 is rotatably connected to a double-ended screw 6, the left end of the sliding frame 4 is threadedly connected to the corresponding end of the double-ended screw 6, a bellows 7 is provided between the left end of the rear inner wall of the clamping frame 1 and the rear surface of the sliding frame 4, and between the left end of the opposite inner surface of the two sliding frames 4 and the left end of the front surface of the front sliding frame 4 and the left end of the front inner wall of the clamping frame 1, the bellows 7 are all sleeved on the outer surface of the double-ended screw 6, the right end of the clamping frame 1 is fixedly connected to a fixing rod 5, the right end of the sliding frame 4 is slidably connected to the outer surface of the fixing rod 5, and the front end of the double-ended screw 6 extends... Extending to the front side of the clamping frame 1, the front end of the double-acting screw 6 is fixedly connected to a handwheel 14. Rotating the handwheel 14 causes the double-acting screw 6 to rotate, which in turn causes the sliding frame 4 to move towards the center of the clamping frame 1. At the same time, the right end of the sliding frame 4 slides on the outer surface of the fixed rod 5, providing sliding support for the movement of the sliding frame 4. During the movement of the sliding frame 4, the bellows 7 extends or retracts accordingly, providing sealing protection for the double-acting screw 6. With the assistance of external measuring tools, when the sliding frame 4 reaches the required position, the handwheel 14 is stopped. The clamping frame 1 has a support frame 13 at its lower end. Support seats 9 are fixedly connected to both the front and rear ends of the upper surface of the support frame 13. Rotating columns 8 are rotatably connected to the upper ends of the support seats 9. The inner surfaces of the two rotating columns 8 are fixedly connected to the clamping frame 1. An adjustment chamber 10 is provided at the rear end of the support seat 9. A worm gear 12 is rotatably connected to the left end of the adjustment chamber 10. A worm wheel 11 is fixedly connected to the rear end of the rotating column 8. The worm wheel 11 and the worm gear 12 are meshed together. According to the installation requirements of the cable reel, the worm gear 12 is rotated. The rotation of the worm gear 12 drives the worm wheel 11 to rotate. The rotation of the worm wheel 11 drives the adjacent rotating column 8 to rotate. The rotation of the rotating column 8 drives the clamping frame 1 to rotate. When the clamped cable reel rotates to the required angle, the rotation of the worm gear 12 is stopped.

[0017] The working principle of the quick assembly fixture for cable reels provided by this utility model is as follows: During operation, the operator first connects the lower end of the support frame 13 to the working plane using bolts, thereby achieving stable installation of the support frame 13, the clamping frame 1, and other mechanisms. After stable installation, the cable reels are placed inside the two arc-shaped seats 21 respectively. Then, the knob 28 is rotated. The rotation of the knob 28 drives the adjacent bidirectional screw 27 to rotate. The rotation of the bidirectional screw 27 causes the two adjacent sliding plates 26 to move. The two sliding plates 26 located inside the same drive chamber 25 move towards the center of the corresponding arc-shaped seat 21, thereby causing the adjacent limiting arc plates 22 of the sliding plates 26 to move towards the corresponding arc-shaped seat 21. The guide plates 24 slide within adjacent guide grooves 23, providing guidance and limiting for the movement of the limiting arc plates 22. Under the guidance of the arrow 16, the spacing between adjacent limiting arc plates 22 effectively meets the clamping requirements of the cable reel. Simultaneously, the inclined rubber strips 29 are tightly fitted to the surface of the cable reel. The inclined tearing force after the inclined rubber strips 29 contact the surface of the cable reel prevents the cable reel from rotating, ensuring stable clamping of the cable reel in real time. Then, the operator rotates the handwheel 14, which drives the bidirectional screw 6 to rotate. The rotation of the bidirectional screw 6 causes the sliding frame 4 to move towards the center of the clamping frame 1. Simultaneously, the right side of the sliding frame 4... Both ends slide on the outer surface of the fixed rod 5, providing sliding support for the movement of the sliding frame 4. During the movement of the sliding frame 4, the bellows 7 extends or contracts accordingly, providing sealing protection for the bidirectional screw 6. With the assistance of external measuring tools, when the sliding frame 4 reaches the required position, the handwheel 14 is stopped, and then personnel assemble the cable reel. At the same time, the components in the cable reel are placed on the upper end of the arc-shaped support plate 31. The arc-shaped support plate 31 is subjected to downward force, which causes the slide rod 32 to slide downward inside the sliding opening. The downward movement of the slide rod 32 drives the limit cap 36 to move downward, which in turn causes the spring 35 to be elastically compressed. The elastic force of the spring 35 reacts to the limit cap 36, and the limit cap 36 transmits the elastic force to the slide rod 32. Finally, the signal is transmitted to the arc-shaped support plate 31, which in turn provides stable support for the internal components of the cable reel. This is in conjunction with the assembly of the cable reel. Simultaneously, the arc-shaped support plate 31 moves downwards, causing the upper end of the connecting rod 34 to move downwards as well. This downward movement of the upper end of the connecting rod 34 causes the connecting shafts at the lower end of the connecting rod 34 to slide within their respective grooves 33. The connecting shafts move away from the center of the clamping frame 1 within their respective grooves 33. Then, according to the installation requirements of the cable reel, the operator rotates the worm gear 12. The rotation of the worm gear 12 drives the worm wheel 11 to rotate, which in turn drives the adjacent rotating column 8 to rotate. The rotation of the rotating column 8 drives the clamping frame 1 to rotate. When the clamped cable reel rotates to the required angle, the rotation of the worm gear 12 is stopped.
