Abstract
Description
Technical Field
[0001] This utility model relates to the field of ironwood cable reel technology, and in particular to a rotatable ironwood reel assembly fixture. Background Technology
[0002] Ironwood reel, also known as ironwood spool or ironwood cable spool, is a reel device used for winding cables. Ironwood reel typically consists of a shaft and discs at both ends of the shaft. During assembly, connecting ribs are generally used to connect the discs and shaft. The connecting ribs are usually metal rods with a circular cross-section. Through holes are provided on the discs and shaft for the connecting ribs to pass through. After the two ends of the connecting ribs pass through the through holes on the discs and shaft, nuts are used to lock and fix the discs and shaft.
[0003] Since both the disc and the shaft are quite heavy, the traditional method of assembling them involves suspending the shaft with a crane, aligning the axes of the disc and the shaft, and aligning the through holes on the disc and the shaft. Then, a metal rod is passed through the through holes on the shaft and the disc, and finally, nuts are installed at both ends of the metal rod to complete the assembly of the ironwood disc. Because the shaft will swing during the suspension process, it is very inconvenient to adjust the height or the horizontal position of the shaft. In addition, the crane's lifting speed is slow, resulting in very low assembly efficiency of the ironwood disc.
[0004] Therefore, it is necessary to propose a rotatable ironwood disc assembly fixture to improve the assembly efficiency of ironwood discs. Utility Model Content
[0005] The purpose of this invention is to solve the problem of low efficiency in existing iron and wood disc assembly methods, and a rotatable iron and wood disc assembly fixture is provided.
[0006] The technical solution of this utility model is: A rotatable iron and wood disc assembly fixture includes a base, a first support frame driven by a ball screw in the middle of the base, the first support frame being slidably connected to the base, and a second support frame with openwork at both ends of the first support frame being rotatably connected to the base. The second support frame is connected to a power device, which can drive the second support frame to rotate until it is parallel to the two end faces of the first support frame. The second support frame is equipped with a fixed plate and a clamp for fixing the plate, and the fixed plate is rotatably connected to the second support frame.
[0007] Furthermore, the clamp includes a telescopic cylinder, a telescopic rod, and a linkage mechanism placed around the telescopic rod. The telescopic rod coincides with the axis of the fixed disk. The telescopic cylinder drives the telescopic rod to move axially along the fixed disk. The linkage mechanism includes a first link and a second link. One end of the first link is hinged to the telescopic rod, and the other end of the first link is hinged to one end of the second link. The other end of the second link is hinged to the fixed disk. The telescopic cylinder is preferably a pneumatic cylinder. When the telescopic cylinder drives the telescopic rod to retract, the first link and the second link rotate relative to each other and move closer to each other, thereby causing the second link to contact the disk and generate a squeezing force, thus fixing the disk to the second support frame.
[0008] Furthermore, the top surface of the first support frame is a concave arc surface, which can better fit the circular side of the shaft.
[0009] Furthermore, the second support frame is circular, and the circular support frame matches the shape of the disc, thereby reducing the footprint.
[0010] Furthermore, the power unit includes a motor, a gearbox, and a drive shaft. The second support frame is fixedly connected to the drive shaft, and the drive shaft is rotatably connected to the base. A driven gear is fixedly connected to the end of the drive shaft. The output end of the motor is connected to the input end of the gearbox, and the output end of the gearbox meshes with the driven gear for transmission. The motor drives the drive shaft to rotate through the gearbox, thereby realizing the rotation of the second support frame, so that the second support frame can be parallel to the base or parallel to the end face of the first support frame.
[0011] Furthermore, the power units are respectively configured at both ends of the base, and the second support frames at both ends of the base are driven by different power units to ensure that the two second support frames can work independently. If one of the second support frames fails, it will not affect the operation of the other second support frame.
[0012] Furthermore, each telescopic rod is equipped with three linkage mechanisms around its perimeter. These three linkage mechanisms are evenly distributed in a ring around the axis of the telescopic rod. This even distribution of the three linkage mechanisms ensures that the pressure on the disc is balanced, thus guaranteeing a secure fixation effect.
[0013] Furthermore, the bottom of the second support frame is provided with a column, which is used to provide support for the second support frame when it is in a horizontal state.
[0014] This utility model discloses a rotatable iron-wood disc assembly fixture. A first support frame supports the shaft, and the disc is placed on a second support frame. A power device drives the second support frame to rotate, aligning the disc with both ends of the shaft. Since the shaft hole on the disc fits onto a fixed disc, the disc is positioned on the second support frame, facilitating alignment between the disc and the shaft axis. A clamp on the second support frame locks and secures the disc, preventing it from falling when the second support frame is erected. The fixed disc can rotate, so when the through hole on the disc does not align with the through hole on the shaft, they can be aligned by rotating the disc, facilitating the passage of connecting ribs. Furthermore, the second support... The frame is hollow, which also facilitates the passage of connecting ribs and the installation of nuts at both ends of the connecting ribs. Compared with traditional technology, this technical solution only requires a crane to place the shaft on the first support frame and the disc on the second support frame. When the second support frame is rotated to stand upright, the disc and the shaft are automatically aligned. When the second support frame is upright, the through hole on the disc is aligned with the through hole on the shaft by rotating the disc. Since the rotation of the disc is supported and rotated by the fixed disc, the operator only needs to move the disc to complete the alignment with the through hole on the shaft, which replaces the suspension of the crane and effectively improves the assembly efficiency of the iron and wood disc.

[0017] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.
[0018] Example 1: like Figure 1 and Figure 2 As shown, this embodiment provides a rotatable iron-wood disc assembly fixture, including a base 1. A first support frame 2 driven by a ball screw is located in the middle of the base 1, and the first support frame 2 is slidably connected to the base 1. Second support frames 3 with openwork are located at both ends of the first support frame 2, and the second support frames 3 are rotatably connected to the base 1. A power device is connected to the second support frame 3, which can drive the second support frame 3 to rotate until it is parallel to the two end faces of the first support frame 2. The second support frame 3 has a fixing plate 4 and a clamp 5 for fixing the disc 14. The fixing plate 4 is rotatably connected to the second support frame 3. Since the ball screw structure is a known drive structure, those skilled in the art can install it according to actual conditions; its specific structure will not be described in detail here. Preferably, the second support frame 3 is welded from sheet metal.
[0019] Preferred, such as Figure 1 and Figure 4 As shown, the clamp 5 includes a telescopic cylinder 6, a telescopic rod 7, and a linkage mechanism placed around the telescopic rod 7. The telescopic rod 7 is aligned with the axis of the fixed disk 4. The telescopic cylinder 6 drives the telescopic rod 7 to move axially along the fixed disk 4. The linkage mechanism includes a first link 8 and a second link 9. One end of the first link 8 is hinged to the telescopic rod 7, and the other end of the first link 8 is hinged to one end of the second link 9. The other end of the second link 9 is hinged to the fixed disk 4. The telescopic cylinder 6 is preferably a cylinder. When the telescopic cylinder 6 drives the telescopic rod 7 to retract, the first link 8 and the second link 9 rotate relative to each other and move closer to each other, so that the second link 9 contacts the disk 14 and generates a squeezing force, thereby fixing the disk 14 to the second support frame 3.
[0020] Preferred, such as Figure 3 As shown, the top surface of the first support frame 2 is a concave arc surface, which can better fit the circular side surface of the shaft 15.
[0021] Preferably, the second support frame 3 is circular, and the circular support frame matches the shape of the disc 14, thereby reducing the floor space occupied.
[0022] Preferred, such as Figure 1As shown, the power unit includes a motor 10, a reduction gearbox 11, and a drive shaft 12. The second support frame 3 is fixedly connected to the drive shaft 12, and the drive shaft 12 is rotatably connected to the base 1. A driven gear is fixedly connected to the end of the drive shaft 12. The output end of the motor 10 is connected to the input end of the reduction gearbox 11, and the output end of the reduction gearbox 11 meshes with the driven gear for transmission. The motor 10 drives the drive shaft 12 to rotate through the reduction gearbox 11, thereby realizing the rotation of the second support frame 3, so that the second support frame 3 can be parallel to the base 1 or parallel to the end face of the first support frame 2.
[0023] Preferably, the power units are respectively configured at both ends of the base 1, and the second support frames 3 at both ends of the base 1 are driven by different power units to ensure that the two second support frames 3 can work independently. If one of the second support frames 3 fails, it will not affect the operation of the other second support frame 3.
[0024] Preferably, each telescopic rod 7 is provided with three linkage mechanisms around its perimeter. The three linkage mechanisms are evenly distributed in a ring around the axis of the telescopic rod 7. The even distribution of the three linkage mechanisms can ensure the pressure balance on the disc 14 and ensure the fixing effect.
[0025] Preferably, the bottom of the second support frame 3 is provided with a column 13, which is used to provide support for the second support frame 3 when it is in a horizontal state.
[0026] At work, such as Figure 5 As shown, place the shaft 15 on the first support frame 2, and place the two discs 14 on the second support frames 3 at the left and right ends respectively; first install the discs 14 onto one end of the shaft 15, as shown. Figure 6 As shown, firstly, a disc 14 is placed flat on the second support frame 3 at the left end. The telescopic rod 7 passes through the shaft hole of the disc 14, and the fixing plate 4 is located in the shaft hole to position the disc 14. Then, the telescopic cylinder 6 drives the telescopic rod 7 to retract, and the rotating first connecting rod 8 and second connecting rod 9 expand outward, thereby blocking the disc 14 and locking it in place. The motor 10 drives the second support frame 3 to rotate to a vertical position. Since the size of the second support frame 3 matches the height of the first support frame 2, the ends of the disc 14 and the shaft 15 can be aligned, eliminating the need for manual alignment of the disc 14 and the shaft 15. This facilitates the installation of connecting ribs and nuts at this end. Since the second support frame 3 has a hollow structure, the connecting ribs can pass through the left side of the second support frame 3 at the left end and enter the shaft 15. Then, a nut is installed on the left side or the outside of the disc 14 at this point to fix the disc 14 and the shaft 15 at this end, completing the installation of the disc 14 on the left end of the shaft 15. Figure 7As shown, the telescopic cylinder 6 at the left end then drives the telescopic rod 7 to extend, releasing the locking of the disc 14. The ball screw drives the first support frame 2 to move to the right relative to the base 1 until the first connecting rod 8, the second connecting rod 9, and the fixed disc 4 at the left end move away from the disc 14 at the left end. The motor 10 drives the second support frame 3 at the left end to return to a horizontal state, placing the second disc 14 flat on the second support frame 3 at the right end. Then, the clamp 5 at the right end of the base 1 (the first connecting rod 8 and the second connecting rod 9 expand outwards) locks in place. The disc 14, driven by the motor 10, rotates the second support frame 3 at the right end to a vertical position. By rotating the disc 14, the holes on it for the connecting ribs align with the holes on the shaft 15 for the connecting ribs. Then, the ball screw drives the first support frame 2 to continue moving to the right, allowing the right end of the shaft 15 to fit against the disc 14. The connecting ribs are then passed through the holes on the right-end disc 14, and a fixing nut is installed on the outside of the right-end disc 14, thus connecting and fixing the shaft 15 to the discs 14 at both ends. Finally, as... Figure 8 As shown, the ball screw drives the first support frame 2 to move to the left, causing the first connecting rod 8, the second connecting rod 9, and the fixed plate 4 on the right end to move away from the disc 14 on the right end. The motor 10 drives the second support frame 3 on the right end to return to a horizontal position. A crane is then used to lift the assembled ironwood axle disc out, thus completing the installation of the ironwood axle disc. Subsequent processing of the ironwood axle disc can be performed by repeating the above steps. Specifically, there are multiple connecting ribs, and nuts are located at both ends of the connecting ribs. This method of fixing with connecting ribs and nuts is currently the most common fixing method for ironwood axle discs and is existing technology, so it will not be elaborated on here.
[0027] This utility model discloses a rotatable iron-wood disc assembly fixture. A first support frame 2 supports a shaft 15, and a disc 14 is placed on a second support frame 3. A power device drives the second support frame 3 to rotate, aligning the disc 14 with both ends of the shaft 15. Since the shaft hole on the disc 14 fits onto the fixed plate 4, the disc 14 is positioned on the second support frame 3, facilitating alignment between the disc 14 and the shaft 15 axis. A clamp 5 on the second support frame 3 locks and secures the disc 14, preventing it from falling when the second support frame 3 is erected. The fixed plate 4 can rotate, so when the through hole on the disc 14 does not align with the through hole on the shaft 15, they can be aligned by rotating the disc 14, facilitating the passage of connecting ribs. Furthermore, the second support frame 3 is hollow, which also facilitates the passage of connecting ribs and the installation of nuts at both ends of the connecting ribs. Compared with traditional technology, this technical solution only requires a crane to place the shaft 15 on the first support frame 2 and the disc 14 on the second support frame 3. When the second support frame 3 is rotated to stand upright, the disc 14 and the shaft 15 can be automatically aligned. When the second support frame 3 is upright, the through hole on the disc 14 can be aligned with the through hole on the shaft 15 by rotating the disc 14. Since the rotation of the disc 14 is supported and rotated by the fixed disc 4, the operator only needs to move the disc 14 to complete the alignment with the through hole on the shaft 15, which replaces the suspension of the crane and effectively improves the assembly efficiency of the iron and wood disc.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
