Description

Technical Field

[0001] The utility model relates to the technical field of tooling, and specifically, to an impeller disassembly and installation tool. Background Art

[0002] In the modern industrial field, due to its unique performance advantages, ceramic materials are increasingly used in the manufacture of impellers. Ceramic impellers have the advantages of high hardness, wear resistance, corrosion resistance, etc., and can exhibit excellent performance in specific working environments. However, due to the characteristics of the ceramic material itself being brittle and easily broken and not resistant to impact, it brings great challenges to its assembly and disassembly.

[0003] Currently, during the assembly and disassembly of impellers, metal tools are usually used. Although these metal tools have certain advantages in terms of strength and durability, when contacting with ceramic impellers, due to their hard material and lack of buffering, they are extremely likely to generate a large impact force during operation, thereby damaging the ceramic impeller and causing abnormal use damage to the ceramic impeller. This situation not only increases the production cost of the enterprise but also may lead to production interruption and affect production efficiency. Summary of the Utility Model

[0022] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0023] Referring to Figures 1 - 2 , for the first embodiment of the present invention, an impeller disassembly and installation tool is proposed, which is used to disassemble or install a ceramic impeller 1, and includes a tool body 2. The tool body 2 has a first abutting arm 21 and a second abutting arm 22. The first abutting arm 21 has a first abutting protrusion 211, and the second abutting arm 22 has a second abutting protrusion 221.

[0024] In this embodiment, the tool body 2 is made of high-strength and lightweight aluminum alloy material to ensure sufficient strength and stability during use, while reducing the weight of the tool for easy operation. The first abutting arm 21 and the second abutting arm 22 are integrally formed with the tool body 2 by precision casting to ensure the firmness and stability of the connection. The first abutting protrusion 211 and the second abutting protrusion 221 are made of wear-resistant rubber material, and the surface has certain elasticity and friction, which can not only protect the surface of the ceramic impeller 1 from damage, but also provide a good abutting effect. In addition, anti-slip patterns or coatings can be provided on the tool body 2 to further improve the holding stability. Consider adding some small protrusions or grooves on the first abutting protrusion 211 and the second abutting protrusion 221 to enhance the contact stability with the surface of the ceramic impeller 1.

[0025] The advantage is that this tool is specifically used for the disassembly and installation of the ceramic impeller 1. Through reasonable structural design, it avoids the damage to the ceramic impeller 1 caused by using metal impeller 1 tools. The settings of the first abutting arm 21, the second abutting arm 22, the first abutting protrusion 211 and the second abutting protrusion 221 can accurately abut against the corresponding parts of the ceramic impeller 1 to achieve stable disassembly and installation operations. The settings of the anti-slip patterns and coatings improve the operation safety, and the design of the small protrusions or grooves enhances the abutting stability.

[0026] Furthermore, the impeller 1 has a first abutting surface 11 and a second abutting surface 12. Both the first abutting surface 11 and the second abutting surface 12 are arc-shaped. The first abutting protrusion 211 is used to abut against the first abutting surface 11 or the second abutting surface 12, and the second abutting protrusion 221 is used to abut against the second abutting surface 12 or the first abutting surface 11.

[0027] In this embodiment, the first abutting surface 11 and the second abutting surface 12 of the impeller 1 adopt high-precision processing technology to ensure the accuracy of the arc shape and the surface smoothness to better cooperate with the first abutting protrusion 211 and the second abutting protrusion 221. The shapes and sizes of the first abutting protrusion 211 and the second abutting protrusion 221 are custom-designed according to the first abutting surface 11 and the second abutting surface 12 of the impeller 1 to ensure a tight fit. In addition, the abutting surface of the impeller 1 can be specially treated, such as coating with a wear-resistant coating, to improve its wear resistance and service life. Further optimize the material selection of the first abutting protrusion 211 and the second abutting protrusion 221 to make it have better wear resistance and corrosion resistance.

[0028] The advantages are that the arc-shaped abutting surface design enables the first abutting protrusion 211 and the second abutting protrusion 221 to contact the impeller 1 more evenly, reducing local stress concentration and protecting the ceramic impeller 1. The tightly fitting design improves the efficiency and accuracy of disassembly and installation. The application of the wear-resistant coating extends the service life of the impeller 1, and the optimized material selection improves the durability of the tool.

[0029] Furthermore, the tool body 2 also has a holding portion 23.

[0030] In this embodiment, the holding portion 23 adopts an ergonomic design, with a shape conforming to the holding habit of the human hand. The surface is wrapped with a soft rubber material to provide a comfortable holding feeling. The connection between the holding portion 23 and the tool body 2 uses a firm threaded connection to ensure that it will not loosen during use. Some uneven textures are provided on the holding portion 23 to increase the frictional force of holding and prevent the hand from slipping. It is possible to consider adding some shock-absorbing materials inside the holding portion 23 to reduce the vibration transmitted to the hand during operation.

[0031] The advantages are that the ergonomically designed holding portion 23 enables the operator to operate more easily and accurately, reducing fatigue. The comfortable holding feeling and the firm connection improve the safety and reliability of tool use. The setting of the uneven textures and shock-absorbing materials further improves the comfort and stability of operation.

[0032] Furthermore, the first abutting arm 21 is semi-circular, and the second abutting arm 22 is linear.

[0033] In this embodiment, the semi-circular design of the first abutting arm 21 can better fit the curved surface part of the impeller 1. The linear design of the second abutting arm 22 facilitates providing a stable support and a force application point during operation. The surface of the second abutting arm 22 is treated to improve its wear resistance and corrosion resistance.

[0034] The advantages are that the semi-circular first abutting arm 21 can increase the contact area with the impeller 1 and enhance the stability of abutment. The linear second abutting arm 22 makes the operation more convenient and accurate, improving work efficiency. At the same time, a receiving space is formed between the semi-circular first abutting portion 21 and the linear second abutting arm 22, which can accommodate impellers 1 of different shapes, and the surface treatment improves the durability of the tool.

[0035] Furthermore, the first abutting protrusion 211 has a third abutting surface 2111, the second abutting protrusion 221 has a fourth abutting surface 2211, the third abutting surface 2111 is used to abut against the first abutting surface 11 or the second abutting surface 12, and the fourth abutting surface 2211 is used to abut against the second abutting surface 12 or the first abutting surface 11.

[0036] In this embodiment, the third abutting surface 2111 of the first abutting protrusion 211 and the fourth abutting surface 2211 of the second abutting protrusion 221 are both designed in an arc shape, and the radian is matched with the abutting surface of the impeller 1. The surfaces of the third abutting surface 2111 and the fourth abutting surface 2211 are smoothed to reduce the friction with the surface of the impeller 1. A soft cushion layer is added on the third abutting surface 2111 and the fourth abutting surface 2211 to further reduce the damage to the impeller 1. The radian of the abutting surface can be finely adjusted to adapt to ceramic impellers 1 of different models.

[0037] The advantages are that the arc-shaped third abutting surface 2111 and fourth abutting surface 2211 can better contact the abutting surface of the impeller 1, improving the stability and accuracy of the abutment. The smooth surface treatment reduces the wear on the surface of the impeller 1 and protects the ceramic impeller 1. The setting of the soft cushion layer further reduces the risk of damage to the impeller 1. The function of fine-tuning the radian improves the adaptability of the tool.

[0038] Furthermore, both the third abutting surface 2111 and the fourth abutting surface 2211 are arc-shaped.

[0039] In this embodiment, the arc-shaped design of the third abutting surface 2111 and the fourth abutting surface 2211 is precisely calculated and simulated to ensure perfect fit with the abutting surface of the impeller 1. The arc-shaped surface is made of high-quality wear-resistant materials to improve its service life. Some patterns or grooves are provided on the arc-shaped surface to enhance the friction with the surface of the impeller 1 and improve the stability of the operation. Regularly check and maintain the abutting surface of the tool to ensure its performance and accuracy.

[0040] The advantages are that the perfectly fitting arc-shaped design can minimize the stress concentration on the ceramic impeller 1 and protect the impeller 1 from damage. The use of wear-resistant materials extends the service life of the tool and reduces the use cost. The setting of the patterns or grooves improves the safety and stability of the operation. Regular inspection and maintenance ensure the reliability of the tool.
