Description

Technical Field

[0001] This utility model relates to the field of shaft hole diameter measurement technology, specifically a device for automatically identifying the center hole diameter of wire packaging shafts. Background Technology

[0002] A cable reel is a carrier for winding cables. It typically consists of a hollow cylinder and two fixed discs. It is suitable for various specifications of wires and cables and can keep the cables neat and orderly for a long time.

[0003] As the diameter of the center hole in the packaging reels for wires increases, workers often store reels with different hollow cylindrical hole diameters together in daily use. This mixes various specifications of reels together, causing difficulties in finding the right reel to match the wire rewinding machine's connecting shaft. If the found reel is incompatible with the connecting shaft, it can easily damage the reel or cause wire wobbling during unwinding. Therefore, determining the compatibility of the hollow cylindrical hole diameter of the reel with the connecting shaft of the wire rewinding machine is a pressing problem that needs to be solved in this technical field.

[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] Please see Figure 1-4 A device for automatically identifying the center hole diameter of a wire packaging shaft includes a support rod 1, a support rod 2, a docking block 3, a movable block 4, a support rod 5, and a distance sensor 7. The docking block 3 is conical in shape, and its surface is designed with a frosted structure. The conical docking block 3 can be easily inserted into the hollow cylinder of a shaft with different hole diameters, facilitating the measurement of hole diameters of shafts of different specifications. A handle 9 is also fixed on the body of the support rod 1, located at the bottom of the fastening screw 10 on the support rod 1. The handle 9 can be used to... For easy handling by staff, one end of support rod 2 is fixed to the bottom side of support rod 1, docking block 3 is fixed to the other end of support rod 2, movable block 4 is set on the top of support rod 1, one end of support rod 3 5 is fixed to the side of movable block 4, and movable block 2 6 is set on the other end of support rod 3 5; a distance sensor 7 is installed on the side of support rod 1 near docking block 3. The distance sensor 7 can be a "LDM301 KJIT distance sensor", which has a display screen to conveniently display the measured values.

[0023] Please see Figure 2 , Figure 3 as well as Figure 4 In this embodiment, a movable rod 602 is fixed on one side of the movable block 6. The end of the movable rod 602 away from the movable block 6 moves through the limiting cavity 1 opened inside the support rod 3 5 and is fixed with a limiting block 1. The limiting block 1 is slidably connected in the limiting cavity 1. A sticker 601 is fixed on the other side of the movable block 6. The side of the sticker 601 away from the movable block 6 is a flat surface.

[0024] Specifically, by extending and retracting the movable rod 602 inside the support rod 5, the distance between the pad 601 and the support rod 5 can be easily adjusted to accommodate shafts with different bore diameters. When the bore diameter of the shaft changes, the position of the pad 601 can be adjusted to ensure that the pad 601 always fits against the fixed plate of the shaft. The limiting block 1 set on the movable rod 602 can ensure the stability of the movable rod 602 during movement.

[0025] Please see Figure 2 as well as Figure 3 In this embodiment, a movable rod 401 is fixed at the bottom of the movable block 4. The end of the movable rod 401 away from the movable block 4 moves through the limiting cavity 2 opened inside the support rod 1 and fixes the limiting block 2. The limiting block 2 is slidably connected in the limiting cavity 2.

[0026] Specifically, by extending and retracting the movable rod 401 inside the support rod 1, the distance between the movable block 4 and the support rod 1 can be adjusted, thereby adjusting the height of the support rod 5 and the mounting block 601. This allows the device to be easily adapted to shaft fixing discs of different sizes, making it more versatile.

[0027] Please see Figure 2 , Figure 3 as well as Figure 4 In this embodiment, both support rod 1 and support rod 3 are threadedly connected to fastening screws 10. One end of each fastening screw 10 is fixed with a pressing block 11. One side of each pressing block 11 is fixed with a rubber sheet 12. One rubber sheet 12 is placed in the limiting cavity 1 and pressed against the movable rod 2 602, and the other rubber sheet 12 is placed in the limiting cavity 2 and pressed against the movable rod 1 401.

[0028] Specifically, by installing fastening screws 10 on the surfaces of support rod 1 and support rod 3 5 respectively, the two fastening screws 10 are used to press the movable rod 1 401 and movable rod 2 602 respectively, ensuring the stability of movable rod 1 401 and movable rod 2 602 and preventing loosening during operation. The rubber sheet 12 can improve the damping effect after pressing, further improving the stability after pressing.

[0029] Please see Figure 1 as well as Figure 2 In this embodiment, cylindrical spirit levels 8 are installed on the surface of support rod 1 and support rod 5, and the cylindrical spirit levels 8 on support rod 1 are arranged vertically and the cylindrical spirit levels 8 on support rod 5 are arranged horizontally.

[0030] Specifically, both the surface of support rod 1 and the surface of support rod 5 have cylindrical spirit levels 8, which can easily determine the stability and levelness of the device during use and improve the accuracy of measurements.

[0031] When using:

[0032] Firstly, this device can be used to measure and record the bore diameters of various specifications of shafts. During inspection, such as... Figure 1 As shown, the conical mating block 3 can be inserted into the hole of the hollow cylinder of the shaft, the fastening screw 10 on the support rod 3 5 can be loosened, the patch 601 can be pulled to fit against the fixed plate of the shaft, and then the fastening screw 10 on the support rod 3 5 can be tightened to fix the movable rod 2 602. Then observe the two cylindrical spirit levels 8 and use the cylindrical spirit levels 8 to calibrate the position of the device to make it stable. Then turn on the distance sensor 7, use the distance sensor 7 to measure the distance to the fixed plate of the shaft and display it. At this time, the value displayed on the distance sensor 7 represents the fixed plate of the shaft of this specification.

[0033] When a shaft is needed, the staff can use this device to measure the diameter of the hollow cylinder of the shaft stacked together one by one. The measurement method is the same as described above. When measuring, if the value displayed on the distance sensor 7 is the same as the value collected by the shaft that has been stored before, it means that the shaft is a suitable shaft and can be used.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
