Description

Technical Field

[0001] This utility model belongs to the field of wrench manufacturing technology, specifically relating to a multifunctional adjustable bearing wrench. Background Technology

[0002] In modern industrial production and machinery maintenance, bearings, as key mechanical components, are widely used in various types of machinery, such as automobiles, machine tools, and aerospace equipment. Bearing installation and removal are common operations in machinery maintenance and assembly. Bearing wrenches, as tools specifically designed for handling bearings, directly impact work efficiency and maintenance quality through their performance and ease of use. Traditional bearing wrenches are mostly fixed-structure single-ended or double-ended wrenches. Single-ended wrenches have limited functionality, only suitable for specific bearing models and specifications. When dealing with various types of bearings, multiple wrenches of different sizes are needed, increasing tool procurement costs and consuming significant storage space. While double-ended wrenches expand their applicability to some extent, the specifications and shapes of both ends remain fixed, failing to meet the complex and ever-changing practical work requirements. With the continuous development of industrial technology, machinery is becoming increasingly precise and complex, demanding higher accuracy in bearing installation and removal. Simultaneously, the diversity of working environments, such as confined spaces and unusual angles, also presents numerous challenges to the use of bearing wrenches. Traditional fixed-structure bearing wrenches are difficult to operate flexibly in these complex environments, resulting in low work efficiency and even damage to bearings or surrounding components due to inconvenience in operation.

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-functional adjustable bearing wrench, which solves the problem that traditional fixed bearing wrenches are difficult to operate flexibly in these complex environments, resulting in low work efficiency, and may even damage the bearing or surrounding parts due to inconvenience of operation.

[0005] (2) Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-functional adjustable bearing wrench, including a gripping rod, a first wrench head, and a second wrench head, wherein the first wrench head and the second wrench head are symmetrically arranged on both sides of the gripping rod;

[0007] Multiple movable sections are rotatably installed on both sides of the grip rod, and the movable sections are sequentially rotated and fastened together.

[0008] Insertion holes are provided on the movable sections near the first and second plate heads.

[0009] Preferably, the first plate head and the second plate head have mounting blocks protruding from the side facing the movable section.

[0010] Preferably, the mounting block is fitted into the socket.

[0013] Preferably, rivets are installed between the movable sections, and springs are connected to the rivets inside the movable sections to maintain their shape and limit their position when bent.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] Flexible Angle Adjustment: Traditional bearing wrenches have a fixed angle, making them difficult to operate in confined spaces or at specific angles. This often requires multiple adjustments to the equipment position or finding the optimal operating angle, wasting considerable time. However, the movable joint design of this wrench allows for flexible adjustment of the wrench head angle. Operators can quickly adjust the wrench head to the optimal operating position without tedious adjustments, significantly reducing operation time and improving work efficiency.

[0017] Quick-release wrench: The replaceable wrench design meets the operational needs of different bearing models. When the wrench needs to be replaced, it can be done simply by inserting, pulling, and tightening the bolts, without the need for additional tools. The operation is simple and quick, further improving work efficiency.

[0018] Enhanced applicability:

[0019] Compatible with a variety of bearings: Because the wrench head can be disassembled and replaced, operators can select the appropriate wrench head for installation according to the different models and specifications of bearings encountered in actual work. This makes the wrench compatible with a variety of bearings, greatly expanding its range of applications. There is no need to equip each bearing with a special wrench, reducing tool procurement costs.

[0020] Ensure operational accuracy and safety:

[0021] Stable Structure: The movable sections are connected by rivets and springs, which limit and maintain their shape when bent, ensuring the wrench's structural stability during operation and preventing wobbling or deformation. Simultaneously, the wrench head is securely connected to the movable section by locking bolts, preventing the wrench head from loosening or falling off during use, ensuring operational accuracy and avoiding operational errors caused by tool instability.

[0022] This wrench features a well-designed overall structure, with a robust and reliable connection between the movable joint and the wrench head. Made from high-quality metal, it boasts high strength and wear resistance. During use, it can withstand significant torque and friction, resisting damage and extending its lifespan while reducing replacement frequency and costs. Attached Figure Description

[0034] This specific embodiment is a multifunctional adjustable bearing wrench, the structural diagram of which is shown below. Figure 1 , Figure 4 As shown, it includes a gripping rod 1, a first plate head 2, and a second plate head 4, with the first plate head 2 and the second plate head 4 symmetrically arranged on both sides of the gripping rod 1;

[0035] Multiple movable sections 3 are rotatably installed on both sides of the gripping rod 1, and the movable sections 3 are sequentially rotated and fastened together; insertion holes are opened on the movable sections 3 near the first plate head 2 and the second plate head 4.

[0036] Reference Figure 2 , Figure 3 The first plate head 2 and the second plate head 4 each have a protruding mounting block 9 on the side facing the movable section 3. The mounting block 9 is fitted into the insertion hole. The side wall of the movable section 3 has a mounting hole 6, through which a locking bolt 8 passes. The mounting block 9 has a threaded hole 7, which is fitted into the locking bolt 8. Rivets 5 are installed between the movable sections 3. The rivets 5 penetrate into the movable section 3 and are connected to a spring, which limits and maintains the shape when bent.

[0037] The working principle of this multi-functional adjustable bearing wrench involves multiple movable sections 3 rotatably mounted on both sides of the grip lever 1, with the sections 3 sequentially rotating and engaging. This design allows the movable sections 3 to rotate relative to each other, thus flexibly changing the overall structural shape of the wrench. When operating the bearing in confined spaces or at special angles, the operator can manually bend the movable sections 3 to adjust the first wrench head 2 and the second wrench head 4 to suitable angles to adapt to different working environments. Simultaneously, rivets 5 are installed between the movable sections 3, with springs connected to the rivets inside the sections 3, acting as tension springs. When bending the movable sections 3, the springs limit and maintain their shape, ensuring that the movable sections 3 remain stable and fixed after adjustment to the required angle, preventing wobbling during use and guaranteeing operational accuracy and safety.

[0038] A socket is provided on the movable section 3 near the first wrench head 2 and the second wrench head 4. Mounting blocks 9 protrude from the sides of the first wrench head 2 and the second wrench head 4 facing the movable section 3, and the mounting blocks 9 are fitted into the sockets. When it is necessary to replace the wrench head with a different specification or model, the operator only needs to pull the mounting block 9 of the old wrench head out of the socket of the movable section 3, and then insert the mounting block 9 of the new wrench head into the socket. The movable section 3 has a mounting hole 6 on its side wall, through which a locking bolt 8 passes. The mounting block 9 has a threaded hole 7. By screwing the locking bolt 8 into the threaded hole 7, the wrench head and the movable section 3 can be firmly connected, preventing the wrench head from loosening or falling off during use. The first wrench head 2 is a bearing wrench. When it is turned in a certain direction, its internal reversing mechanism (internal ratchet) drives the one-way bearing to lock, and the output shaft drives the working part to rotate, thereby tightening or loosening the bolt. When it is turned in the opposite direction, the one-way bearing slides and the output shaft remains stationary, avoiding interference from reverse torque. Before operation, confirm that the locking direction of the one-way bearing is consistent with the operation requirements to avoid damage to the tool or stripping of the bolt due to reverse force.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
