Description

Technical Field

[0001] This invention relates to the field of bolt and nut assembly and disassembly technology, specifically to a bolt and nut assembly and disassembly processing platform for preventing loosening and its assembly and disassembly method. Background Technology

[0002] Bolts and nuts are commonly used fastening components. During the production of bolts and nuts, it is necessary to determine the compatibility between the bolts and nuts through assembly. The assembly process is completed by an automated processing platform. However, existing bolts and nuts still have certain defects in the assembly and disassembly process. During the processing of bolts and nuts, most of them are assembled manually by workers. Manual assembly has low production efficiency, high labor intensity for workers, and is prone to errors.

[0003] Patent publication number CN221773889U discloses an automatic bolt and nut assembly fixture. Through the cooperation of a rotating mechanism and a transmission mechanism, the bolt and nut are first pushed into the transmission groove three by a hydraulic cylinder. The nut is located in a fixing ring, while the bolt is fixed by a magnet. A lifting rod drives the nut upward, and simultaneously, a motor drives the magnet to rotate, thus rotating the bolt and assembling it with the nut. This improves assembly speed, increases assembly accuracy, reduces labor intensity, improves consistency and stability, and achieves automated production. With the cooperation of the transmission mechanism, during normal use, the bolt and nut can be pushed and moved by hydraulic cylinders one and two through transmission grooves one, two, and three, saving time and manpower, improving assembly efficiency, reducing the risk of accidental injury and error to workers, and improving work safety.

[0004] Patent announcement number CN210849111U discloses an automatic bolt and nut assembly fixture. Addressing the issue that existing subway projects use large bolts and nuts, resulting in low efficiency and inconsistent quality with manual assembly, this automatic bolt and nut assembly fixture is designed. A hexagonal nut is loaded into a nut clamping mechanism, and the bolt's shank is loaded onto the bolt clamping mechanism with the bolt head facing the tightening mechanism. The fixing center of the nut clamping mechanism, the clamping center of the bolt clamping mechanism, and the rotation center of the tightening mechanism coincide with the centers of the bolt and the hexagonal nut. The tightening mechanism gradually moves towards the nut clamping mechanism and contacts the bolt head, continuing to push the bolt tail towards the hexagonal nut until it abuts against the central through-hole of the hexagonal nut. Simultaneously, the tightening mechanism drives the bolt to rotate while simultaneously driving the nut clamping mechanism to move and pass through the hexagonal nut, thus assembling the bolt and hexagonal nut. This automated assembly method significantly reduces the labor intensity of manual assembly, improving assembly efficiency and quality.

[0005] In the aforementioned patent, the assembly tooling solves the problems mentioned above. However, the assembly tooling still has the following problems: during the operation of the tooling, it is necessary to use a fixing structure to position the nuts and bolts to ensure the accuracy of the bolt and nut connection. However, the fixing ring inside the fixing structure has a fixed size, and it can only limit the position of nuts of the same size during use. When limiting the position of nuts of different sizes, it is easy for the position to be offset, which can affect the positioning and assembly between the bolt and nut, resulting in a limited scope of application for the assembly tooling.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing processing platform structure. Summary of the Invention

[0007] The purpose of this invention is to provide a bolt and nut assembly and disassembly processing platform and its assembly and disassembly method to prevent loosening.

However, the fixed ring inside the fixed structure has a fixed size, which can only limit the position of nuts of the same size during use. When limiting the position of nuts of different sizes, it is easy for the position to be offset, which can affect the positioning and assembly between the bolt and nut, resulting in the limited applicability of the assembly tooling.

[0016] Preferably, a rotating gear cylinder is rotatably mounted inside the motion plate, and a motion gear plate is slidably mounted inside the motion plate. The motion gear plate is meshed with the rotating gear cylinder.

[0023] 4. Furthermore, the downward movement of the moving plate is achieved by using an elastic pull rope to move the sliding plate, which allows the sliding plate to clamp the nut through the clamping block, effectively demonstrating the ingenuity of the structure and simultaneously completing the automatic positioning of the nut.

[0035] 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.

[0036] Example 1: This embodiment is an example Figures 1-6 As shown, in order to solve the problem that existing machining platforms have difficulty in automatically clamping bolts, the process of automatically clamping bolts by this machining platform is disclosed, achieving the effect of stable clamping of bolts by the machining platform. The specific content is as follows:

[0037] Support plate 1 and support rod 2 fixedly installed on the upper end of support plate 1;

[0038] A processing plate 3 is fixedly installed on the upper end of the support rod 2, and a conveying mechanism 4 is provided inside the processing plate 3. A support frame 5 is fixedly installed on the upper end of the processing plate 3, and a horizontal plate 6 is fixedly installed on the upper end of the support frame 5. An electric push rod 7 is fixedly installed on the lower end of the horizontal plate 6, and a lifting plate 8 is fixedly installed on the lower end of the electric push rod 7.

[0039] The upper end of the processing plate 3 is provided with a clamping structure for limiting the bolts; the clamping structure includes a moving plate 20 and a moving block 21. The moving block 21 is slidably installed inside the support frame 5, and the moving plate 20 is fixedly installed on the outside of the moving block 21. The upper end of the moving plate 20 is fixedly installed with a telescopic rod 19, and the upper end of the telescopic rod 19 is fixedly connected to the lifting plate 8.

[0040] A rotating gear cylinder 22 is rotatably mounted inside the moving plate 20, and a moving gear plate 23 is slidably mounted inside the moving plate 20. The moving gear plate 23 is meshed with the rotating gear cylinder 22. A telescopic rod 24 is fixedly mounted at the end of the moving gear plate 23 away from the rotating gear cylinder 22, and a support spring 25 is provided on the outside of the telescopic rod 24. At the same time, a docking piece 26 is fixedly mounted at the end of the telescopic rod 24 away from the moving gear plate 23.

[0041] The clamping structure also includes a lower rack 27 and an upper rack 28. The lower rack 27 is fixedly installed on the upper end of the processing plate 3, and the upper rack 28 is fixedly installed on the upper end of the lower rack 27. Both the upper rack 28 and the lower rack 27 are meshed with the rotating gear cylinder 22.

[0042] When using this anti-loosening bolt and nut assembly and disassembly processing platform, first place the processing platform in the position where the work needs to be carried out. After placing the processing platform in the required position, the bolts and nuts can be processed.

[0043] In this process, the nuts need to be conveyed by the conveying mechanism 4, and the bolts are placed between the two sets of moving plates 20 by the external electric equipment. The bolt positioning and conveying is the existing technology, which will be further explained here. The bolt rod is clamped by the groove between the two sets of moving plates 20, so that the bolt head is located at the upper end of the two sets of moving plates 20. At this time, the electric push rod 7 can work and drive the lifting plate 8 to move downward.

[0044] At this time, the two sets of moving plates 20 are located between the lower rack 27 and the upper rack 28. When the lifting plate 8 moves downward, it will drive the moving plate 20 to move downward through the telescopic rod 19. The moving block 21 will slide downward inside the support frame 5. During this process, the rotating gear cylinder 22 will contact the lower rack 27 and rotate under the action of the lower rack 27. At this time, the rotating gear cylinder 22 will rotate and drive the moving gear plate 23 to move. The movement of the moving gear plate 23 will drive the telescopic rod 24 and the docking piece 26 to move. At this time, the two sets of docking pieces 26 will approach each other and clamp the bolt rod. During the clamping of bolt rods of different sizes, the telescopic rod 24 and the support spring 25 will retract and complete the clamping of the bolt rod, so that the structure can process bolts of different sizes.

[0045] After the bolt rod is clamped, the bolt and nut can be rotated and installed. After installation, the electric push rod 7 will retract and the moving plate 20 will move upward, so that the upper rack 28 will mesh with the rotating gear cylinder 22. At this time, the two sets of mating parts 26 can be moved away, so that the installed bolt and nut can fall to the upper end of the conveying mechanism 4 and be conveyed. By limiting the bolt rod, the accuracy of the nut and bolt installation can be ensured and the bolt and nut can be prevented from loosening.

[0046] Example 2: This embodiment is an example Figures 1-4 and Figures 8-9 As shown, in order to solve the problem that existing equipment has difficulty in clamping nuts of different sizes, the processing process of this processing platform for nuts of different sizes is disclosed, realizing the effect that the processing platform can process nuts of different sizes. The specific content is as follows:

[0047] The upper end of the processing plate 3 is provided with a positioning structure to limit the nut; the positioning structure includes a positioning plate 33, which is fixedly installed on the upper end of the processing plate 3 and located on the upper end of the conveying mechanism 4. A sliding plate 32 is slidably installed inside the positioning plate 33, and a return spring 29 is fixedly installed on the end of the sliding plate 32 near the positioning plate 33. The return spring 29 is fixedly connected to the positioning plate 33. An elastic pull rope 31 is fixedly installed on the upper end of the sliding plate 32, and the end of the elastic pull rope 31 away from the sliding plate 32 is fixedly connected to the moving plate 20. The elastic pull rope 31 passes through the support frame 5. At the same time, a clamping block 30 is fixedly installed on the end of the sliding plate 32 away from the return spring 29.

[0048] When using the anti-loosening bolt and nut assembly and disassembly processing platform, as the moving plate 20 moves downward, it will pull the sliding plate 32 through the elastic pull rope 31. The movement of the sliding plate 32 will cause the return spring 29 to expand, and the sliding plate 32 will clamp the nut conveyed at the upper end of the conveying mechanism 4 through the clamping block 30, thereby completing the limiting process of the nut.

[0049] After the nut is clamped, the moving plate 20 will continue to move downward. At this time, the elastic rope 31 will deform and stretch, so that the bolt clamped at the upper end of the moving plate 20 can contact the nut, which makes it easier to clamp nuts of different sizes and facilitates the installation between bolts and nuts.

[0050] Furthermore, as the moving plate 20 moves upward, the expanded return spring 29 will contract and pull the sliding plate 32 to reset, while the deformed elastic rope 31 will reset synchronously, making it easier to clamp the nut next time.

[0051] Example 3: This embodiment is an example Figures 1-7 As shown, in order to solve the problem that existing machining platforms are difficult to use for rotating and machining bolts of different sizes, the process of clamping and rotating bolts on this machining platform is disclosed, thus achieving the effect that the machining platform can be used for machining bolts of different sizes. The specific details are as follows:

[0052] The lower end of the lifting plate 8 is provided with a rotating structure for clamping bolts; the rotating structure includes a drive motor 9 and a worm gear 10. The drive motor 9 is fixedly installed at the lower end of the lifting plate 8, and the output end of the drive motor 9 is fixedly installed with the worm gear 10, and the worm gear 10 is rotatably connected to the lower end of the lifting plate 8.

[0053] The rotating structure also includes a turntable 11, which is rotatably mounted on the lower end of the lifting plate 8, and a worm gear 12 is fixedly mounted on the outer side of the turntable 11, while the worm gear 12 is meshed with the worm 10.

[0054] A rotating screw 15 is rotatably mounted inside the turntable 11, and a threaded block 17 is threadedly mounted on the outer side of the rotating screw 15. A clamping member 18 is fixedly mounted on the outer side of the threaded block 17, and the clamping member 18 is slidably connected to the turntable 11.

[0055] The lower end of the turntable 11 has a clamping opening 13. The clamping member 18 is set with an inlaid inverted "V" shape at the end near the clamping opening 13. The end of the rotating screw 15 away from the clamping member 18 is fixedly installed with a driven gear 16, which is located inside the worm gear 12. The worm gear 12 is fixedly installed with a fixed gear ring 14, which meshes with the driven gear 16. The turntable 11 has a limit block 34 slidably installed inside, which engages with the worm gear 12. The end of the limit block 34 near the turntable 11 is fixedly installed with a compression spring 35.

[0056] After the moving plate 20 and moving block 21 move to the lower end of the support frame 5, the electric push rod 7 can continue to move and push the lifting plate 8 downward. At this time, the turntable 11 at the lower end of the lifting plate 8 will move to the outside of the bolt head and make the bolt head located inside the clamping port 13. Then, the drive motor 9 can drive the worm gear 10 to rotate, and the rotation of the worm gear 10 will drive the worm wheel 12 to rotate. At this time, the worm wheel 12 will drive the driven gear 16 to rotate through its internal fixed gear ring 14. Wheel 16 drives rotating screw 15 to rotate, causing the threaded block 17 and clamping member 18 on the outside of rotating screw 15 to move. At this time, the two sets of clamping members 18 inside turntable 11 will approach each other and clamp the bolt head. During this process, limit block 34 and worm gear 12 are separated. During this process, compression spring 35 is compressed. The outer thread of rotating screw 15 has the same direction of rotation as the outer thread of existing reciprocating screw, so that the clamping member 18 can clamp bolt heads of different sizes.

[0057] Then, the drive motor 9 can drive the worm gear 10 to rotate in the opposite direction. At this time, the limit block 34 and the worm wheel 12 are engaged, and the compression spring 35 is in an expanded state. Then, the worm wheel 12 drives the turntable 11 to rotate through the limit block 34. The rotation of the turntable 11 will drive the clamped bolt head to rotate through the clamping member 18, thereby assembling the bolt with the nut at its lower end. During this process, the electric push rod 7 will expand to complete the assembly process of the nut and bolt. By repeating the above operation in the opposite direction, the assembled nut and bolt can be disassembled, thereby improving the ease of use of the processing platform and increasing its overall practicality.

[0058] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

At the same time, the two groups of clamping pieces (18) in the rotating disc (11) will move close to each other and clamp the bolt head; S4: After the threaded head is fixed and clamped, the threaded head can be rotated and the bolt rod can be butt jointed with the nut. The driving motor (9) drives the worm (10) to rotate in the opposite direction, so that the limiting block (34) and the worm wheel (12) are in the engaged state. Then the worm wheel (12) drives the rotating disc (11) to rotate through the limiting block (34). The rotation of the rotating disc (11) drives the clamped bolt head to rotate through the clamping piece (18), so that the bolt and the nut at the lower end are assembled, thereby the assembling and butt joint process of the nut and the bolt in the method is disclosed. Thus the overall operation process of the assembling method is completed.
