Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design and manufacturing, in particular to a gear auxiliary disassembly and assembly fixture. Background Art

[0002] The gear assisted disassembly fixture is a process device specially designed for gear disassembly operations. It is used to accurately and efficiently fix and position gears for installation or disassembly. The gear assisted disassembly fixture is a tool specially designed to support the gear assembly and disassembly process. It can ensure the correct position and stability of the gear during mechanical work.

[0003] The existing Chinese patent (publication number CN209110954U) discloses a gear auxiliary disassembly and assembly tool. When performing disassembly and assembly operations, according to the size of the gear to be disassembled, a suitable movable gear is selected and installed in the gear installation cavity of the disassembly and assembly body, and then the disassembly and assembly cavity of the movable gear is fitted onto the gear to be disassembled, and the handle is pressed down to firmly fix the gear, and then the gear fixing bolt is removed; the same is true for installing the gear. This tool greatly improves work efficiency and greatly improves the inherent safety of the site, avoiding the risk of personal injury and gear damage.

[0004] Although the above technical solution provides the flexibility of selecting movable gears according to different sizes, in actual operation, workers may need to carry movable gears of various specifications to adapt to different work requirements. This not only increases the complexity of operation, but also increases the risk of losing small parts. The design of the tool may not be able to adapt to all types of gears, especially those with non-standard sizes or shapes. This limits the universal applicability and flexibility of the tool. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provide a gear auxiliary disassembly and assembly fixture.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a gear auxiliary disassembly and assembly fixture, comprising a mounting shell and a mounting port fixedly connected to the mounting shell, wherein a disassembly assembly is arranged on the mounting shell;

[0007] The disassembly assembly includes a rotating shaft, a rolling member is fixedly connected to the rotating shaft, a sliding member is slidably connected to the rolling member, a connecting plate is fixedly connected to the side of the sliding member away from the rotating shaft, and a connecting member is fixedly connected to the connecting plate.

[0008] As a preferred embodiment, a grab hook is fixedly connected to the connecting member, a connecting ring is provided on the grab hook, and the connecting ring is fixedly connected to the installation port.

[0009] The technical effect of adopting the above-mentioned further scheme is: by providing a grab hook, the gear can be easily fixed. When in use, the transmission of the rolling element can be achieved by rotating the rotating shaft. When the rolling element rolls, the sliding element will slide on the rolling element. After sliding to the recessed position on the rolling element, it will be retracted inwardly under the action of the sliding element, so that the end of the connecting plate away from the bottom plate is clamped inward, so that the grab hook clamps the gear.

[0010] As a preferred implementation, a bottom plate is fixedly connected to a side of the mounting shell away from the mounting opening, and the rotating shaft is rotatably connected to the bottom plate.

[0011] The technical effect of adopting the above further solution is that the bottom plate is provided to facilitate connection of the rotating shaft.

[0012] As a preferred implementation, a sliding groove is provided on the rolling member, and the sliding member is slidably connected in the sliding groove on the rolling member.

[0013] The technical effect of adopting the above further solution is: by providing a sliding groove, limiting sliders are provided at both ends of the sliding member, and the limiting sliders on the sliding member are slidably connected to the rolling member, thereby achieving the limitation of the sliding member.

[0014] As a preferred embodiment, two sliding members are provided, and the two sliding members are arranged in an array with the rolling member as the center.

[0015] The technical effect of adopting the above further solution is: by providing two sliding members, the gear can be clamped, thereby avoiding the problem that only one sliding member and the grab hook are provided and cannot clamp the gear.

[0016] As a preferred embodiment, the two sliding members are both slidably connected to the rolling member.

[0017] The technical effect of adopting the above further solution is: by setting the two sliding members to be slidably connected to the rolling member, the two sliding members can be limited in position, and the two sliding members can be driven simultaneously when in use.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the present invention, the combined use of rolling elements and sliding elements not only simplifies the assembly and maintenance process, but also enables the clamp to adapt to gears of different sizes and shapes. The position of the rolling elements is controlled by rotating the shaft, thereby adjusting the degree of opening and closing of the grab hook. This design provides a high degree of adjustability, allowing the tool to adapt to a wider range of operating requirements.

[0020] 2. In the utility model, the design of the clamp focuses on user experience. For example, complex actions can be achieved by simply manually rotating the shaft, which greatly reduces the difficulty of operation and reduces the possibility of operational errors. Due to the efficient interactive design between the sliding parts and the rolling parts, the operator's input can be quickly converted into the action of the clamp, improving work efficiency. It is especially suitable for occasions where gears need to be replaced quickly. The application of the sliding groove on the rolling part provides an accurate motion track for the sliding part, ensuring the smoothness and accuracy of the operation. This design also helps to maintain the long-term durability of the components and reduce additional wear caused by deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] This embodiment provides a technical solution, such as Figures 1 to 4 As shown, a gear auxiliary disassembly and assembly fixture includes a mounting shell 1 and a mounting port 11 fixedly connected to the mounting shell 1, and a disassembly component 2 is arranged on the mounting shell 1;

[0030] The disassembly assembly 2 includes a rotating shaft 26, a rolling member 21 is fixedly connected to the rotating shaft 26, a sliding member 22 is slidably connected to the rolling member 21, a connecting plate 23 is fixedly connected to the side of the sliding member 22 away from the rotating shaft 26, and a connecting member 24 is fixedly connected to the connecting plate 23;

[0031] The combined use of the rolling element 21 and the sliding element 22 in the disassembly component 2 not only simplifies the assembly and maintenance process, but also enables the clamp to adapt to gears of different sizes and shapes. The position of the rolling element 21 is controlled by rotating the shaft 26, thereby adjusting the opening and closing degree of the grab hook 27. This design provides a high degree of adjustability, allowing the tool to adapt to a wider range of operating requirements.

[0032] Further, such as Figure 1 , Figure 2 As shown, a grab hook 27 is fixedly connected to the connecting member 24, and a connecting ring 25 is provided on the grab hook 27. The connecting ring 25 is fixedly connected to the mounting port 11. The grab hook 27 is provided to facilitate fixing the gear. When in use, the rolling member 21 can be transmitted by rotating the rotating shaft 26. When the rolling member 21 rolls, the sliding member 22 will slide on the rolling member 21. After sliding to the recessed position on the rolling member 21, it will be retracted inwardly under the action of the sliding member 22, so that the end of the connecting plate 23 away from the bottom plate 12 is clamped inwardly, so that the grab hook 27 clamps the gear.

[0033] A bottom plate 12 is fixedly connected to one side of the mounting shell 1 away from the mounting opening 11 , and the rotating shaft 26 is rotatably connected to the bottom plate 12 . The bottom plate 12 is provided to facilitate connection of the rotating shaft 26 .

[0034] In the above solution, there is still a situation where the sliding member 22 slips when the sliding member 22 rolls on the rolling member 21, such as Figure 1 as well as Figure 2 As shown, a sliding groove is provided on the rolling member 21, and the sliding member 22 is slidably connected in the sliding groove on the rolling member 21. By providing the sliding groove, limit sliders are provided at both ends of the sliding member 22, and the limit sliders on the sliding member 22 are slidably connected to the rolling member 21, so as to limit the sliding member 22;

[0035] There are two sliding members 22, and the two sliding members 22 are arranged in an array with the rolling member 21 as the center. By providing two sliding members 22, the gear can be clamped, avoiding the problem that only one sliding member 22 and the grab hook 27 cannot clamp the gear.

[0036] The two sliding members 22 are both slidably connected to the rolling member 21. By arranging that the two sliding members 22 are both slidably connected to the rolling member 21, it is possible to limit the position of the two sliding members 22 and to drive the two sliding members 22 simultaneously when in use.

[0037] Working principle:

[0038] like Figure 1-4 As shown: by providing a disassembly component 2, when in use, the rotation of the rolling member 21 is achieved by rotating the rotating shaft 26, and the rolling member 21 will drive the two sliding members 22 to slide on the rolling member 21 while moving up and down slightly, so that the connecting plate 23 drives the connecting member 24 and the grab hook 27 to clamp inward, so that the gear is clamped, and then the device is pushed outward by external force to achieve the disassembly of the gear. The combined use of the rolling member 21 and the sliding member 22 in the disassembly component 2 of the clamp not only simplifies the assembly and maintenance process, but also enables the clamp to adapt to gears of different sizes and shapes. The position of the rolling member 21 is controlled by the rotating shaft 26, and then the opening and closing degree of the grab hook 27 is adjusted. This design provides a high degree of adjustability, so that the tool can adapt to a wider range of operating requirements.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
