[0030] Implementation Method 1

[0031] This embodiment relates to a through-hole nut mounting fixture, which mainly solves the problem of simultaneous assembly and disassembly of the handle plate 3, the first fixture plate 1, and the second fixture plate 2. The fixture includes the following main components:

[0032] First jig plate 1: Used to support and fix the mold positioning pin 11 and the nut hanging pin 12. The first jig plate 1 fixes the mold positioning pin 11 through the optical axis support 14. The end of the positioning pin extends into the corresponding positioning hole of the mold to achieve positioning. The first jig plate 1 is in the shape of "I" and has a hollow design at both ends and in the middle to reduce the overall weight and improve the flexibility of operation.

[0033] Second fixture plate 2: used to carry fixed nut cylinder 21 and bearing guide column 22. Second fixture plate 2 and first fixture plate 1 realize relative motion through linear bearing 13 and bearing guide column 22. The second fixture plate 2 is a structure with wide two sides and narrow middle, and a "1" shaped linear hollow slot is arranged in the middle. A plurality of nut cylinders 21 are connected to one side, and bearing guide column 22 is fixed to the other side and opposite to the first fixture plate 1.

[0034] Linear bearing 13: The linear bearing 13 is sleeved and fixed on the first fixture plate 1, and the bearing guide column 22 is movably arranged in the linear bearing 13, so as to realize the relative motion between the first fixture plate 1 and the second fixture plate 2. The end of the linear bearing 13 is fixed on the side of the first fixture plate 1 corresponding to the second fixture plate 2 by a screw, and the top end penetrates the first fixture plate 1 and is located on the side of the first fixture plate 1 corresponding to the handle plate 3. The bearing guide column 22 moves in the linear bearing 13, thereby realizing the relative motion of the two plates.

[0035] Nut cylinder 21: fixed on the second fixture plate 2, used for installing nuts. The fixed end of the nut cylinder 21 is connected to the side of the second fixture plate 2 away from the first fixture plate 1, and the other end of the nut cylinder 21 abuts against a nut with the same diameter, which is used for the penetration of the nut hanging needle 12, realizes the precise butt joint of the nut and the hanging needle, and ensures that the nut cylinder 21 can lift the nut from the nut hanging needle 12.

[0036] Nut hanging needle 12: The fixed end of the nut hanging needle 12 is pressed and fixed on the first fixture plate 1 by the pressing block 15, penetrates the nut cylinder 21 and the end of the nut hanging needle 12 is exposed from the nut cylinder 21. The nut hanging needle 12 penetrates the first fixture plate 1 and the second fixture plate 2, and the fixed end of the nut hanging needle 12 is on the side of the first fixture plate 1 corresponding to the handle plate 3. The fixed end of the nut hanging needle 12 has a diameter larger than that of other parts, and is firmly locked by the pressing block 15 and the first fixture plate 1, so as to ensure that the hanging needle does not move during operation. The other end of the nut hanging needle 12 movably penetrates the nut cylinder 21, and the length of the nut hanging needle 12 is greater than the diameter of the nut cylinder 21 and less than the inner diameter of the nut, so that the nut can be easily hung.

[0037] Multi-prism support 31: Penetrates the movable hole of the first fixture plate 1, and two ends are provided with installation threads in opposite directions, so as to be simultaneously installed on the handle plate 3 and the second fixture plate 2. After the assembly return spring 32 is assembled, the handle plate 3, the first fixture plate 1 and the second fixture plate 2 can be disassembled. The multi-prism support 31 penetrates the first fixture plate 1, and two ends are connected to the handle plate 3 and the second fixture plate 2 respectively. The multi-prism support 31 abuts against the handle plate 3, and the support is fixed by a screw penetrating the handle plate 3. The other end is embedded in the preset hole of the second fixture plate 2, and the diameter of the preset hole is smaller than the diameter of the multi-prism support 31. The embedded end of the support matches the diameter of the preset hole, so as to achieve the effect of abutting and fixing at the same time. By arranging a plurality of prisms on the support, the rotation of the wrench is facilitated without affecting the movement.

[0038] Reset spring 32: sleeved on the polygonal pillar 31, and the two ends are respectively against the handle plate 3 and the first jig plate 1, by applying pressure to the reset spring 32, and through the elastic force, to realize the automatic reset of the jig assembly.

[0039] Embodiment two

[0040] The handle plate 3 is located on the side of the first jig plate 1 corresponding to the optical axis support 14, and is connected with the first jig plate 1 through the polygonal pillar 31. The handle plate 3 is in a strip shape, and a long strip-shaped groove with a semicircular head is formed on the side of the handle plate 3 corresponding to the first jig plate 1 along the length direction. The groove reduces the weight of the handle plate 3, provides a comfortable holding feeling for the operator, ensures the structural strength of the handle plate 3, prevents deformation, has an anti-skid effect compared with a cylindrical handle, and is designed according to ergonomics, improves operation convenience, ensures that the operator's hands are not easy to fatigue in long-time use, and improves work efficiency.

[0041] Embodiment three

[0042] The handle plate 3 is made of bakelite material, which has good insulation performance and mechanical strength. The bakelite material ensures that the handle plate 3 is light and firm, effectively reduces the overall weight, improves operation flexibility, and prolongs the service life. In the operation process, the handle plate 3 made of bakelite material can effectively insulate heat and prevent static interference, so that the jig can still work stably in a high-temperature or electromagnetic environment, and is suitable for jigs that need to be frequently disassembled.

[0043] Embodiment four

[0044] A limiting bolt 33 is arranged between the handle plate 3 and the first jig plate 1, a limiting screw hole is formed on the handle plate 3, the connecting end of the limiting bolt 33 is screwed into the limiting screw hole, and is fixed by a screw. The limiting bolt 33 is located in the middle of the two polygonal pillars 31, and one end needs to abut against the second jig plate 2 during movement. Therefore, a bottom cylinder with a diameter larger than the bottom surface of the limiting bolt 33 is formed on the end of the limiting bolt 33 corresponding to the second jig plate 2, so as to increase the contact area with the second jig plate 2, ensure that the limiting bolt 33 is not easy to slip off when stressed, improve the firmness of the overall structure, and when the handle plate 3 drives the second jig plate 2 to move, the space between the handle plate 3 and the first jig plate 1 is compressed. By arranging the limiting bolt 33, it is ensured that the operator's hands will not be injured due to excessive compression, and the maximum stroke is limited to prevent the jig assembly from being damaged due to over-limit movement. By arranging the limiting bolt 33 to set the relative stroke of the first jig plate 1 and the second jig plate 2, the limiting bolt 33 can also adjust the stroke distance and be fixed according to needs, so as to realize accurate control of the movement range of the jig, and improve the accuracy and flexibility of operation.

[0045] Fifth Embodiment

[0046] The linear bearing 13 includes a mounting plate and a cylinder formed by extending the middle part of the mounting plate, and the cylinder is sleeved on the bearing guide column 22. The mounting plate is fixed on the first jig plate 1 by screws. The mounting plate is a long strip structure with a circular arc shape, and is fixed on the corresponding one side of the first jig plate 1 by screws at both ends. The middle part of the mounting plate extends and penetrates the first jig plate 1 to form a cylinder, and the inner diameter of the cylinder forms a channel for the bearing guide column 22 to slide, ensuring that the bearing guide column 22 can move smoothly. In actual use, the mold positioning pin 11 will be deflected after being used for many times. Compared with the prior art of integrating the mold positioning structure and the jig movement guide structure, the mold positioning pin 11 and the bearing guide column 22 combined as one structure will inevitably rub against the linear bearing 13, reducing the smoothness during use. The mold positioning structure and the jig movement guide structure are designed separately in the present application, effectively avoiding the above-mentioned influence, reducing wear and prolonging service life. The linear bearing 13 is located on both sides of the multi-prism pillar 31, and between the hollow grooves at both ends and in the middle of the first jig plate 1, so that the bearing guide column 22 moves evenly between the two jig plates, ensuring the stability of the bearing and the precise movement of the jig.

[0047] Sixth Embodiment

[0048] The fixed end of the nut hanging needle 12 is a cylinder with a larger diameter than the nut hanging needle 12, and the pressing block 15 is provided with a U-shaped notch matching the size of the cylinder. The two ends of the pressing block 15 press and fix the cylinder on the first jig plate 1 by locking screws. The U-shaped notch of the pressing block 15 is arranged towards the first jig plate 1, and the two ends of the pressing block 15 are fixed towards the first jig plate 1 by screws. The fixed end of the nut hanging needle 12 is located between the fixing screws and stops in the middle of the U-shaped notch, so that the U-shaped notch fits the cylindrical structure of the fixed end, ensuring the stability and reliability of the nut hanging needle 12.

[0049] Seventh Embodiment

[0050] The installation end of the nut holder 21 is a pull rivet nut fixed on the second jig plate 2 by screwing. The installation end of the nut holder 21 is embedded in one end of the second jig plate 2. The pull rivet nut is stepped, and the cross section is a multi-prism shape in contact with the second jig plate 2 and a cylindrical shape. The multi-prism structure facilitates tool twisting, and the cylindrical part further enhances the stability of the installation end, ensuring that the nut holder 21 does not easily loosen under stress. This design allows the nut holder 21 to be quickly replaced, improving the applicability and flexibility of the jig.

[0051] Eighth Embodiment

[0052] The through-hole nut mounting jig is suitable for the jig of embedding nuts in the mold of the LED display screen bottom shell. The jig ensures the accurate position of the nuts during the embedding process in the mold through precise positioning and fixing design, avoids installation errors caused by displacement, improves the overall assembly quality and efficiency of the LED display screen bottom shell, and is suitable for stable operation of large-scale production lines. The jig has a simple structure, is easy to operate, is designed in a modular way, is easy to install and disassemble, reduces production costs, improves production efficiency, ensures the consistency of product quality, and is suitable for various precise assembly requirements. The specific application design makes the jig more professional and meets the production needs of specific products.

[0053] Working principle: The through-hole nut mounting jig is composed of the handle plate 3, the first jig plate 1 and the second jig plate 2. In the initial state, the mounting plate of the linear bearing 13 is located between the first jig plate 1 and the second jig plate 2, which is used to divide the two jig plates. First, the mold positioning pin 11 is aligned with the mold positioning hole and inserted, which fixes the position between the first jig plate 1 and the mold. Then, the handle plate 3 is pushed, the bearing guide column 22 slides in the linear bearing 13, and the pressure on the homing spring 32 is started. The multi-prism support 31 moves in the first jig plate 1, driving the second jig plate 2 to move synchronously. The movement of the handle plate 3 compresses the space of the first jig plate 1, and the limit bolt 33 of the handle plate 3 stops on the first jig plate 1. At this time, the nut driver cylinder 21 moves along the nut hanging needle 12, and finally covers the exposed part of the nut hanging needle 12, so as to push the nut on the nut hanging needle 12 to the predetermined position of the LED display screen bottom shell, ensuring the accurate embedding of the nut and completing the embedding process in the mold. Then, the handle plate 3 is loosened, and each part is reset by the rebound force of the homing spring 32, and the jig returns to the initial state for next use.

[0054] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
