Description

Technical Field

[0001] This utility model belongs to the field of ultra-precision machining equipment, and in particular relates to an ultra-precision tooling magnetic pole with a ceramic ring. Background Technology

[0002] During the ultra-precision machining of bearings in the manufacturing workshop, the direct contact between the product and the magnetic pole can lead to scratches and blackening of the product's end face. These issues are particularly prominent in the current processing and significantly impact the product's forming quality and production progress. This results in rework of the processed parts, greatly increasing production costs. Furthermore, the friction between the product and the magnetic pole causes the magnetic pole to wear out too quickly, leading to frequent magnetic pole repairs and equipment adjustments. This negatively affects the morale of the operators and increases their workload.

[0003] To address the above issues, existing technologies often involve adding a ceramic ring to the magnetic pole. Because the ceramic ring has good hardness, it significantly reduces workpiece damage and blackening during processing. The conventional approach involves preparing a ceramic ring compatible with the magnetic pole and bonding it to it. While this meets daily processing needs, long-term use of the magnetic pole may lead to loosening of the ceramic ring due to adhesive aging, and thermal stress caused by temperature changes due to material differences between the ceramic ring and the magnetic pole suction head can affect the processing and fail to meet usage requirements. Utility Model Content

[0004] This invention addresses the technical problems existing in the connection effect between the magnetic pole and the ceramic ring mentioned above, and proposes a reasonable design, simple structure, convenient processing method that can replace bonding to achieve a stable connection between equipment components. At the same time, it allows for convenient replacement of the magnetic pole with ceramic ring to address wear and tear after long-term use, ensuring work progress and fully meeting the usage requirements.

[0005] To achieve the above objectives, the present invention adopts a high-precision tooling magnetic pole with a ceramic ring, comprising a tooling magnetic pole body with an L-shaped cross-section. An annular groove is formed on the upper inner side of the tooling magnetic pole body. A limiting block is provided on the upper outer side of the tooling magnetic pole body. A wave-shaped tube with an annular wave design is provided on the inner side of the limiting block. A ceramic ring with an L-shaped cross-section is provided on the upper part of the tooling magnetic pole body. An annular tube that is adapted to and engages with the annular groove is provided on the inner side of the ceramic ring.

[0006] Preferably, the limiting block is designed in an arc shape, and an adapter groove is opened in the ceramic ring corresponding to the limiting block. A connecting screw hole is opened in the ceramic ring corresponding to the limiting block, and an installation screw hole is opened in the limiting block.

[0007] Preferably, the ceramic ring is provided with a transition layer, a wear-resistant layer and a friction-reducing layer from bottom to top.

[0008] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides an ultra-precision tooling magnetic pole with a ceramic ring. Utilizing a limiting block, it can limit the position of the waveform tube to ensure its stability, and also limit the position of the ceramic ring to ensure the connection stability between the ceramic ring and the tooling magnetic pole. Furthermore, the ceramic ring is connected to the tooling magnetic pole via a snap-fit ​​and threaded connection, enabling convenient installation of the device and ensuring good functionality of the equipment components to meet usage requirements.

[0011] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0012] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0013] Examples, such as Figures 1-5 As shown, a high-precision tooling magnetic pole with a ceramic ring 4 includes a tooling magnetic pole body 1. The tooling magnetic pole body 1 has an L-shaped cross-section. Process holes are provided inside the tooling magnetic pole body 1 for mounting it on a high-precision machine, ensuring the stability of the equipment component installation. Further, an annular groove 11 is provided on the upper inner side of the tooling magnetic pole body 1, and a limiting block 2 is provided on the upper outer side of the tooling magnetic pole body 1. This limiting block 2 can limit the position of the corrugated tube 3 to ensure its stability, and also limit the position of the ceramic ring 4 to ensure the connection stability between it and the tooling magnetic pole. A corrugated tube 3 with an annular wave design is provided inside the limiting block 2. For the corrugated tube 3: it uses a metal corrugated tube with a specific coefficient of thermal expansion as a transition connector. One end of the corrugated tube 3 is placed within multiple limiting blocks 2, and its… The outer periphery is engaged with the limiting block 2 to ensure the stability of the corrugated tube 3's position. A ceramic ring 4 with an L-shaped cross-section is provided above the tooling magnetic pole body 1. A ring tube 41 that is adapted to and engaged with the ring groove 11 is provided on the inner side of the ceramic ring 4. In other words, the lower outer side of the ceramic ring 4 is sleeved on the outer side of the corrugated tube 3, and the outer periphery of the corrugated tube 3 is in contact with the inner side of the ceramic ring 4. The inner side of the corrugated tube 3 is in contact with the upper outer periphery of the tooling magnetic pole. When the ceramic ring 4 is placed on the outer side of the corrugated tube 3, the corrugated tube 3 can be placed between the ceramic ring 4 and the tooling magnetic pole. As the device operates, when temperature changes cause different thermal expansions between the magnetic pole and the ceramic ring 4, the corrugated tube absorbs the displacement difference through its flexible deformation, effectively alleviating thermal stress concentration, reducing the possibility of equipment damage, and relatively extending the functionality of the device to meet usage requirements. In the above process: the established limiting block 2 can limit the position of the waveform tube 3 to ensure its stability, and can also limit the position of the ceramic ring 4 to ensure the stability of its connection with the tooling magnetic pole. Furthermore, the ceramic ring 4 is connected to the tooling magnetic pole by snap-fit ​​and threaded connection, realizing convenient installation of the device and ensuring that the equipment components have good functionality and meet the usage requirements. This device is reasonably designed, simple in structure, easy to process, and can replace the adhesive method to achieve stable connection between equipment components. At the same time, it can be easily replaced for wear and tear after long-term use, ensuring the work progress and fully meeting the usage requirements.

[0014] To further improve the rationality of the device's design, the limiting block 2 is arc-shaped, and the ceramic ring 4 corresponding to the limiting block 2 has an adapter groove 42. The adapter groove 42 is adapted to the limiting block 2. When installing the ceramic ring 4, the two can engage the ceramic ring 4 with the tooling magnetic pole. Furthermore, the ceramic ring 4 corresponding to the limiting block 2 has a connecting screw hole 43, and the limiting block 2 has an installation screw hole 21. With the above design, after the ceramic ring 4 is engaged with the tooling magnetic pole, the installation screw is used to connect the ceramic ring 4 with the installation screw hole 21 of the limiting block 2 through the connecting screw hole 43. This design can further tighten the installation of the ceramic ring 4, prevent it from shifting, improve the stability of the device components, and meet the usage requirements.

[0015] To further improve the strength of the ceramic ring 4, a transition layer 5, a wear-resistant layer 6, and a friction-reducing layer 7 are sequentially formed from bottom to top on the ceramic ring 4. Specifically, the transition layer 5 is an alumina transition layer, which is directly attached to the surface of the ceramic ring 4 substrate as the bottom layer. It has excellent compatibility and bonding strength with the ceramic material. As a bonding layer, it ensures good adhesion between the coating and the ceramic ring 4 substrate. The wear-resistant layer 6 is a silicon nitride wear-resistant layer, which serves as an intermediate layer above the transition layer 5, providing the main wear resistance due to its high hardness. Excellent wear resistance, withstanding the main wear during processing. The friction-reducing layer 7 is a solid lubricant-containing friction-reducing layer, which is placed on the outermost side as the surface layer and in contact with the processed product. It contains solid lubricant components to provide self-lubricating properties and effectively reduce frictional resistance during processing. The above adopts a gradient design, with the performance of each layer transitioning gradually. This not only ensures a firm bond between the coating and the substrate, but also achieves dual optimization of wear resistance and friction reduction through functional layering design. This greatly improves the setting effect of the ceramic ring 4, ensures the processing and forming quality of the workpiece, and meets the usage requirements.

[0016] 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.
