Description

Technical Field

[0001] This utility model relates to the field of evaporator fan technology, and in particular to a tooling for disassembling an evaporator fan impeller. Background Technology

[0002] In the daily maintenance, repair, and manufacturing of evaporator fans, impeller disassembly is a common and important task. However, existing methods for disassembling evaporator fan impellers have many shortcomings. Traditional disassembly methods often require a variety of complex and specialized tools, resulting in cumbersome procedures that consume significant time and labor costs and demand high levels of expertise from operators. Improper tool use or incorrect operation during disassembly can easily damage the impeller itself and other components of the fan, affecting the overall performance and lifespan of the fan. Furthermore, the installation locations of some evaporator fan impellers are often in unique and confined spaces, making conventional disassembly tools difficult to use, further increasing the difficulty of disassembly. Therefore, existing technologies cannot efficiently, conveniently, and safely complete the disassembly of evaporator fan impellers, necessitating the design of a specialized disassembly fixture to address these issues.

[0004] To achieve the above and other related objectives, the technical solution provided by this utility model is: an evaporator impeller disassembly fixture, including a base, a screw rod that passes through the upper and lower end faces is screwed at the center of the base, and a handle for driving the screw rod to rotate is fixed at one end of the screw rod near the top side of the base; multiple sets of pull hooks that can be flipped up and down are hinged on the periphery of the base, and multiple sets of locking mechanisms are also provided on the base, the locking mechanisms being configured to lock the pull hooks to maintain a pulled state.

[0005] The preferred technical solution is that the base is provided with multiple sets of hinge ears arranged at equal angles on its periphery, and the tops of the multiple sets of hooks are hinged to the multiple sets of hinge ears in a corresponding manner.

[0006] The preferred technical solution is as follows: the locking mechanism consists of a locking member, a guide post, and a locking bolt. The guide post is fixed on the base, and the locking bolt is screwed on the base. The locking member includes a horizontal section and a vertical section. The horizontal section is provided with an arc-shaped guide strip hole. The guide post and the locking bolt are both inserted into the arc-shaped guide strip hole. The vertical section is correspondingly matched with the outer side of the hinge ear.

[0007] A preferred technical solution is as follows: a support tube is fixedly provided on the bottom side of the base, the screw passes through the support tube, and the support tube is configured to be sleeved on the rotating shaft of the evaporator impeller.

[0008] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0009] This utility model provides a tooling for disassembling an evaporator impeller. By hinged multiple sets of up-and-down flip-up hooks on the periphery of the base, and in conjunction with a locking mechanism, the hooks can be firmly locked to maintain the pulling state. This design allows the tooling to pull the impeller stably from multiple directions during disassembly, ensuring that the impeller is subjected to uniform force during the disassembly process, avoiding damage to the impeller due to excessive local force, and effectively improving the safety and reliability of disassembly.

A handle 3 for driving the screw 2 to rotate is fixed at one end of the screw 2 near the top side of the base 1. Multiple sets of pull hooks 4 that can be flipped up and down are hinged on the periphery of the base 1. Multiple sets of locking mechanisms are also provided on the base 1. The locking mechanisms are configured to lock the pull hooks 4 to keep them in a pulled state.

Compared with the traditional disassembly method, the operation process is greatly simplified and the professional skills required of the operator are reduced. Even those with relatively little experience can quickly get started to disassemble the impeller.

[0022] Stable and secure: Multiple sets of hinged, tiltable hooks on the periphery of the base, combined with a locking mechanism, securely lock the hooks to maintain the pulling state. This design allows the tooling to pull the impeller stably from multiple directions during disassembly, ensuring even force distribution on the impeller during disassembly and preventing damage due to excessive localized force, thus effectively improving the safety and reliability of disassembly.

[0023] Excellent adaptability: The support tube fixed to the bottom of the base can be fitted onto the shaft of the evaporator fan impeller, providing stable support and positioning for the entire disassembly process. This design allows the tooling to be well-suited for disassembling different models of evaporator fan impellers, offering strong versatility and reducing the hassle of changing disassembly tools due to differences in fan models, thus improving work efficiency.

[0024] Simple structure and low cost: The overall structure of this disassembly fixture is relatively simple. The components used, such as screws, hooks, and locking parts, are common mechanical parts that are easy to manufacture and procure. Compared with some complex specialized disassembly equipment, it greatly reduces manufacturing costs and also facilitates later maintenance and upkeep.
