Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic processing technology, and in particular relates to an ultrasonic rolling tool head. Background Technology

[0002] With the rapid development of the precision manufacturing industry, ultrasonic rolling technology is increasingly widely used in aerospace, automotive parts, and precision molds due to its ability to effectively improve workpiece surface quality and enhance material properties. As the core actuator of this technology, the ultrasonic rolling tool head's structural stability and motion accuracy directly determine the final machining effect, thus placing stringent requirements on its design.

[0003] Existing tool heads mostly use single or simple connection structures (such as single-level threaded connections, snap-fit ​​connections, etc.) to assemble various components, lacking a multi-layered, coordinated fixing mechanism. During tool head installation, insufficient connection strength can easily lead to misalignment of components. During ultrasonic rolling operations, high-frequency vibrations further exacerbate the risk of loosening at the connection points—for example, gaps may appear in the connection between the sliding disc and the outer ring, and threaded connections may unravel, ultimately causing the overall structure of the tool head to shift. This not only affects the continuity of operations but may also cause quality problems such as scratches on the workpiece surface and out-of-tolerance machining dimensions, and may even lead to damage to tool head components.

[0004] Furthermore, existing tool heads have weak ability to constrain the motion path of core working components (such as the rolling actuation end). Most rely solely on a single structure of the outer ring or sliding disk for coarse positioning, lacking a dual constraint mechanism for component positions. On the one hand, the sliding disk is prone to displacement due to imperfect guiding structures when sliding within the ring, leading to unstable tool head mounting positions. On the other hand, the lack of precise positioning and mating structures between components (such as the sliding disk and the threaded disk) prevents the formation of coordinated trajectory constraints, causing the tool head to easily deviate from the preset machining path during rolling operations. Ultimately, this results in inconsistent machining accuracy and large surface roughness fluctuations in the same batch of workpieces, making it difficult to meet the mass production requirements of precision parts.

[0005] The aforementioned problems not only limit the application potential of ultrasonic rolling technology but also increase the scrap rate and maintenance costs during the production process. Therefore, it is necessary to develop an ultrasonic rolling tool head with a multi-layered fixed structure that can precisely define the motion trajectory. Utility Model Content

[0006] To achieve the above objectives, this utility model proposes an ultrasonic rolling tool head, including an outer ring, a sliding disk slidably mounted inside the outer ring, a tool head disposed above the sliding disk, a threaded disk rotatably mounted above the sliding disk, and a thread corresponding to the threaded disk disposed inside the outer ring.

[0007] In one example, a connecting ring is slidably provided on the outer ring sidewall, and an installation ring is fixed on the outer ring sidewall.

[0008] In one example, a spring rod is fixedly mounted at the bottom of the mounting ring, and a connecting ring is disposed at the bottom of the spring rod.

[0009] In one example, the bottom of the outer ring is rotatably equipped with a rotating disk.

[0010] In one example, an arc-shaped column is fixedly installed above the rotating disk.

[0011] In one example, the arc-shaped column extends through both the sliding disk and the threaded disk.

[0012] In one example, the sliding disk and the threaded disk have arc-shaped circular holes inside.

[0013] The ultrasonic rolling tool head proposed in this utility model can bring the following beneficial effects:

[0014] 1. This utility model uses an outer ring to provide basic fixed support and prevent the tool head from shifting as a whole. The threaded disc screwed into the outer ring can strengthen the connection between the sliding disc and the outer ring. The arc-shaped column prevents relative movement between the sliding disc and the threaded disc by passing through them. The limit block inserted into the rotating disc can fix the rotating disc. The multi-layered fixing structure works together to effectively prevent the tool head components from loosening during installation and ultrasonic rolling operations, providing a stable guarantee for operation.

[0015] 2. In this invention, the movement path of the tool head can be precisely defined after the sliding plate slides into the outer ring. The tool head maintains a stable installation position by relying on the support and trajectory of the sliding plate. Furthermore, the arc-shaped column can accurately penetrate the arc-shaped holes inside the sliding plate and the threaded plate, further constraining the position of the component. Under the dual effect, it can prevent the tool head from deviating from the preset trajectory during operation, significantly improving the positional accuracy and workpiece processing quality consistency of ultrasonic rolling.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0027] Example:

[0028] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes an ultrasonic rolling tool head, which includes an outer ring 11. The outer ring 11 can fix the entire tool head and provide basic fixed support for the entire tool head, ensuring that the overall structure of the tool head will not shift during subsequent installation and use, thus ensuring the stability of the tool head installation. During use, the sliding disk 12 is slid into the outer ring 11 from top to bottom. The sliding disk 12 restricts the movement trajectory of the tool head. By sliding into the outer ring 11, the movement path of the tool head is precisely defined, preventing the tool head from deviating from the preset trajectory during installation and subsequent operations, thus ensuring the accuracy of the tool head's working position. The tool head is fixedly set above the sliding disk 12, relying on the support and trajectory limitation of the sliding disk 12 to ensure its own stable installation position, providing a reliable working component carrier for subsequent ultrasonic rolling operations, and ensuring the positional accuracy of the tool head during operation.

[0029] At this point, the threaded disc 13, positioned above the sliding disc 12, is rotated counterclockwise. The threaded disc 13 is then screwed into the outer ring 11. This counterclockwise screwing into the outer ring 11 further strengthens the connection between the sliding disc 12 and the outer ring 11, making the sliding disc 12 more secure within the ring and preventing it from loosening or shifting. Simultaneously, the connecting ring 14 is pulled downwards, moving it away from the side wall of the outer ring 11 to avoid interference. This provides space for the subsequent stretching of the spring rod 16 and structural reset. The spring rod 16 is also stretched under the tension of the connecting ring 14, resulting in elastic deformation and storing elastic potential energy. This provides power for the reset action when the connecting ring 14 is released, ensuring that the subsequent limit block can successfully complete the fixing operation.

[0030] The mounting ring 15 on the side wall of the outer ring 11 will remain stationary, providing force to the connecting ring 14 and maintaining a fixed state. This provides a stable force support point for the connecting ring 14, ensuring balanced force distribution during pulling and preventing damage or displacement of the connecting ring 14 due to unstable force, thus ensuring smooth operation. Meanwhile, rotating the rotating disk 17 at the bottom of the outer ring 11 will drive the upper arc-shaped column 18 in a circular motion. This rotational motion transmits power to the arc-shaped column 18, providing the necessary force for the arc-shaped column 18 to subsequently penetrate the sliding disk 12 and the threaded disk 13. The required motion power is the key transmission component for fixing the sliding disk 12 and the threaded disk 13. The arc-shaped column 18 will directly penetrate and extend into the interior of the sliding disk 12 and the threaded disk 13 according to the arc-shaped circular hole 19 inside the sliding disk 12 and the threaded disk 13, and fix the sliding disk 12 and the threaded disk 13. Guided by the arc-shaped circular hole 19, it accurately penetrates the sliding disk 12 and the threaded disk 13, and tightly connects the two through physical penetration, preventing relative movement of the sliding disk 12 and the threaded disk 13 in subsequent operations and ensuring the stability of the connection between the two.

[0031] At this point, when the connecting ring 14 is released, the limiting block inside the connecting ring 14 will be directly inserted into the rotating disk 17 for fixation. Under the action of the spring rod 16's restoring force, it moves with the connecting ring 14 and is inserted into the rotating disk 17. After insertion, the rotating disk 17 is fixed through physical engagement, preventing the rotating disk 17 from loosening later, thereby ensuring the stability of the entire tool head fixing structure, so that the tool head is directly fixed inside the outer ring 11.

[0032] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
