Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a quick-installation tooling for copper rings. Background Technology

[0002] In the fields of machinery manufacturing and related industries, copper rings are widely used in equipment such as motors and transformers as important conductive or sealing components.

[0003] Currently, copper rings are mostly installed manually. Workers need to align the copper ring with the installation position and then slowly slip it onto the designated part. This installation method has many problems: on the one hand, manual operation is inefficient, consuming a lot of time and labor costs, and it is difficult to meet the needs of large-scale production; on the other hand, because the precision of manual operation is difficult to guarantee, it is easy to cause inaccurate installation of the copper ring, affecting the overall performance and service life of the equipment. In addition, some copper rings are small in size and soft in texture. During the installation process, workers' fingers can easily squeeze and deform the copper ring, further reducing product quality.

[0004] Therefore, this utility model proposes a quick installation tool for copper rings. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a quick-installation tooling for copper rings.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick-installation fixture for copper rings, including a base assembly, the base assembly being composed of a base plate, and further comprising:

[0007] An expansion assembly is composed of four expansion frames arranged on a base frame. The four expansion frames are arranged in a ring. A limit component is provided between the four expansion frames. A drive frame is provided on the base frame between the four expansion frames. A clamping push rod is provided on the drive frame. The other end of the clamping push rod is connected to the expansion frame.

[0008] The limiting assembly consists of a limiting rod and a limiting sleeve disposed between the four expansion frames, and a telescopic adjustment component is provided between the limiting sleeve and the expansion frame.

[0009] Furthermore, there are four telescopic adjustment components, which are arranged in a ring, and the included angle between two adjacent telescopic adjustment components is equal to the included angle of the expansion frame.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the drive frame pushes the four expansion frames to slide outward synchronously along the limiting sliding frame through the clamping push rod, thereby realizing the expansion and positioning of the copper ring; the limiting rod cooperates with the limiting sleeve and provides elastic support through the telescopic adjustment component to ensure that the expansion force is evenly distributed; the sliding cooperation between the sliding seat and the sliding upright ensures the vertical movement of the expansion frame and avoids deformation of the copper ring.

[0011] Furthermore, the limiting rod is provided with limiting discs on both the upper and lower sides of the limiting sleeve, and the diameter of the limiting discs is larger than the diameter of the limiting sleeve.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the limiting discs at the upper and lower ends of the limiting rod have a larger diameter than the limiting sleeve, forming upper and lower stroke stops. When the expansion frame drives the limiting sleeve to slide along the limiting rod, the upper limiting disc prevents the sleeve from coming out, and the lower limiting disc limits the maximum expansion amount. The mechanical limiting ensures the movement accuracy of the expansion frame.

[0013] Furthermore, a base frame is provided at the bottom of the base plate, and multiple base frames are provided, with the multiple base frames arranged in a ring.

[0014] The beneficial effects of adopting the above-mentioned further scheme are: the multiple base frames distributed in a ring form a stable support structure through the base plate, which evenly distributes the self-weight of the tooling and the radial force during the expansion process to the support surface. The ring layout of the base frame and the distribution of the expansion frame form a geometric correspondence, so that the thrust of the clamping push rod is transformed into a symmetrical expansion force through the base plate, ensuring that the copper ring is subjected to balanced force.

[0015] Furthermore, a limiting sliding frame is provided at the top of the base plate, and a sliding groove is provided at the bottom of the expansion frame. The expansion frame is slidably connected to the limiting sliding frame and the sliding groove.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the limiting sliding frame and the sliding groove form a dovetail groove pair structure. When the clamping push rod drives the expansion frame to move radially, the sliding groove slides linearly along the guide rail surface of the limiting sliding frame, realizing the precise guidance of the expansion frame, and bearing both radial force and vertical component force to ensure motion accuracy.

[0017] Furthermore, a sliding seat is provided at the bottom of the expansion frame, and a sliding upright is slidably connected to the sliding seat. The bottom of the sliding upright is connected to the base frame.

[0018] The beneficial effects of adopting the above-mentioned further scheme are: the sliding upright and the sliding seat form a vertical guide pair. When the expansion frame moves radially along the limiting sliding frame, the sliding seat slides synchronously on the sliding upright. This structure decomposes the expansion force into horizontal and vertical components, and eliminates the pitching and tilting tendencies of the expansion frame through the double guide rail constraint.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the drive frame synchronously drives four annularly distributed expansion frames to move radially along the limiting sliding frame via clamping push rods. The limiting rod and limiting sleeve of the limiting assembly are elastically connected through telescopic adjustment components. When the expansion frame slides outward, the limiting sleeve moves synchronously along the limiting rod. The telescopic adjustment components provide buffer damping and balance the expansion force. The limiting plate limits the maximum expansion stroke through the diameter difference, ensuring the synchronicity of the four sets of expansion frames. The sliding seat and the sliding upright form a vertical guide pair, eliminating pitch and tilt during the expansion process and decomposing the expansion force into a horizontal expansion component and a vertical support component.

[0030] 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.

[0031] like Figure 1-5As shown, this utility model provides a technical solution: a quick-installation fixture for a copper ring, including a base assembly 1, which is composed of a base plate 12, and further including:

[0032] Expansion assembly 2 is composed of expansion frames 21 set on the base frame 11. There are four expansion frames 21 in total, and the four expansion frames 21 are arranged in a ring. A limit assembly 3 is set between the four expansion frames 21. A drive frame 13 is set on the base frame 11 between the four expansion frames 21. A clamping push rod 131 is set on the drive frame 13. The other end of the clamping push rod 131 is connected to the expansion frame 21.

[0033] The limiting component 3 consists of a limiting rod 31 and a limiting sleeve 33 disposed between the four expansion frames 21. A telescopic adjustment component 331 is provided between the limiting sleeve 33 and the expansion frame 21. The drive frame 13 synchronously drives the four annularly distributed expansion frames 21 to move radially along the limiting sliding frame 14 through the clamping push rod 131. The limiting rod 31 and the limiting sleeve 33 of the limiting component 3 are elastically connected through the telescopic adjustment component 331. When the expansion frame 21 slides outward, the limiting sleeve 33 moves synchronously along the limiting rod 31. The telescopic adjustment component 331 provides buffer damping and balances the expansion force. The limiting plate 32 limits the maximum expansion stroke through the diameter difference to ensure the synchronicity of the four sets of expansion frames 21. The sliding seat 23 and the sliding upright 24 form a vertical guide pair to eliminate pitch and tilt during the expansion process and decompose the expansion force into a horizontal expansion component and a vertical support component.

[0034] There are four telescopic adjustment components 331 arranged in a ring. The included angle between two adjacent telescopic adjustment components 331 is equal to the included angle between the expansion frame 21. The drive frame 13 pushes the four expansion frames 21 to slide outward synchronously along the limiting sliding frame 14 through the clamping push rod 131 to realize the expansion and positioning of the copper ring. The limiting rod 31 cooperates with the limiting sleeve 33 and provides elastic support through the telescopic adjustment components 331 to ensure that the expansion force is evenly distributed. The sliding seat 23 and the sliding upright 24 slide to ensure that the expansion frame 21 moves vertically and avoids deformation of the copper ring.

[0035] Limiting discs 32 are provided on both the upper and lower sides of the limiting sleeve 33 on the limiting rod 31. The diameter of the limiting discs 32 is larger than the diameter of the limiting sleeve 33. Because the diameter of the limiting discs 32 at the upper and lower ends of the limiting rod 31 is larger than that of the limiting sleeve 33, they form upper and lower travel stops. When the expansion frame 21 drives the limiting sleeve 33 to slide along the limiting rod 31, the upper limiting disc 32 prevents the sleeve from falling out, and the lower limiting disc 32 limits the maximum expansion amount. The mechanical limiting ensures the movement accuracy of the expansion frame 21.

[0036] The bottom of the base plate 12 is provided with a base frame 11. There are multiple base frames 11, and the multiple base frames 11 are arranged in a ring. The multiple base frames 11 arranged in a ring form a stable support structure through the base plate 12, which evenly distributes the self-weight of the tooling and the radial force during the expansion process to the support surface. The ring layout of the base frame 11 is geometrically corresponding to the distribution of the expansion frame 21, so that the thrust of the clamping push rod 131 is converted into a symmetrical expansion force through the base plate 12, ensuring that the copper ring is subjected to balanced force.

[0037] The top of the base plate 12 is provided with a limiting sliding frame 14, and the bottom of the expansion frame 21 is provided with a sliding groove 22. The expansion frame 21 is slidably connected to the sliding groove 22 through the limiting sliding frame 14. The limiting sliding frame 14 and the sliding groove 22 form a dovetail groove pair structure. When the clamping push rod 131 drives the expansion frame 21 to move radially, the sliding groove 22 slides linearly along the guide rail surface of the limiting sliding frame 14 to achieve precise guidance of the expansion frame 21, while bearing radial force and vertical component force to ensure motion accuracy.

[0038] The bottom of the expansion frame 21 is provided with a sliding seat 23, and a sliding upright 24 is slidably connected to the sliding seat 23. The bottom of the sliding upright 24 is connected to the base frame 11. The sliding upright 24 and the sliding seat 23 form a vertical guide pair. When the expansion frame 21 moves radially along the limiting sliding frame 14, the sliding seat 23 slides synchronously on the sliding upright 24. This structure decomposes the expansion force into horizontal and vertical components, and eliminates the pitching and tilting tendencies of the expansion frame 21 through the double guide rail constraint.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
