Description

Technical Field

[0001] This utility model relates to the field of heavy-duty AGV heavy-duty drive axle assembly technology, and in particular to a mandrel tooling for assembling a trackless navigation heavy-duty AGV heavy-duty drive axle. Background Technology

[0002] Due to the limited lifting points for steering system components (the steering components are large, heavy, and irregularly shaped, with uneven weight distribution, making them prone to tilting after lifting and posing safety hazards), they require lifting for docking with the drive axle support beam. However, the irregular shape of the drive axle support beam makes it difficult to arrange the lifting points, resulting in unreliable lifting points. This leads to docking difficulties and the risk of slippage during docking. The entire docking process is time-consuming and the docking accuracy is not high, directly affecting the subsequent drilling and reaming positioning accuracy, and thus posing a significant risk of failing to achieve the required turning angle as designed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heavy-duty drive axle assembly mandrel tooling for trackless navigation heavy-duty AGVs in the industrial logistics industry that is convenient to use, quick to assemble and disassemble, highly applicable, overcomes the problem of unstable hoisting and docking of drive axle support beams, and has high safety performance.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a mandrel tooling for assembling a heavy-duty drive axle of a trackless navigation heavy-duty AGV, the innovation of which lies in: including A central steel pipe, wherein the central steel pipe is arranged horizontally; A left-side round steel bar is laterally fixed to the left side of the central steel pipe, and the central steel pipe and the left-side round steel bar are coaxially arranged. A right-side round steel bar is laterally fixed to the right side of the central steel pipe, and the outer diameter of the right-side round steel bar and the left-side round steel bar are the same. The central steel pipe is coaxially arranged with the left and right round steel bars.

[0005] Furthermore, the outer diameter of the central steel pipe is larger than the outer diameter of the left-side round steel.

[0006] Furthermore, both the extended side of the left round steel and the extended side of the right round steel are provided with a shaft head, and the outer diameter of the shaft head is larger than the diameter of the left round steel.

[0007] Furthermore, a connecting plate is threadedly connected to the center position of the extended side of the axle head. When the axle head passes through the inner hole of the steering system component, a connecting plate can be set on the outside of the steering system component and connected to the axle head with bolts. This enables precise positioning of the steering system component and facilitates the subsequent precise docking and installation of the steering system component and the drive axle support beam.

[0008] Furthermore, a left partition block is fixed between the left round steel and the central steel pipe, and a right partition block is fixed between the right round steel and the central steel pipe. Both the left and right partition blocks are solid, which can improve the structural stability and safety of the mandrel.

[0009] Furthermore, the lateral length of the left partition is greater than that of the right partition, thus providing a placement margin, which is suitable for the assembly and use of various heavy-duty drive axles. At the same time, it can also prevent the left partition from getting stuck in the center hole of the drive axle support beam, improving ease of use.

[0010] Furthermore, the diameter of the right partition is larger than the diameter of the left partition, and the diameter of the right partition is slightly smaller than the inner hole of the steering system component, so that the spindle and the inner hole adopt a clearance fit to avoid getting stuck in the inner hole.

[0011] Furthermore, the diameter of the left partition is equal to the diameter of the shaft head.

[0012] The advantages of this utility model are: 1. This mandrel fixture is simple to manufacture and easy to operate. First, pass the left side of the mandrel through the center hole of the drive axle support beam, then position it through the outer center of the two end shafts, and connect it to the inner hole of the support joint of the steering system component. This one-step process saves time and effort and greatly improves assembly efficiency. At the same time, the mandrel and the inner hole of the steering system component use a clearance fit, avoiding the phenomenon of the mandrel fixture itself getting stuck in the inner hole and difficult to disassemble. It is not limited by site conditions and facilitates the docking and installation of heavy-duty drive axle support beams and steering system components, greatly improving assembly efficiency and ease of operation.

[0013] 2. This structure is safe and reliable, portable, quick to assemble and disassemble, highly adaptable, and simple to manufacture. It effectively overcomes the low assembly efficiency and unstable hoisting and docking of heavy-duty drive axles; avoids the risks of unreliable lifting points, difficult docking, and slippage during the process; reduces unnecessary bumps and scratches; ensures the appearance quality and assembly safety of the drive axle support beam; and also protects the lifting tools and ropes used, thereby reducing safety hazards during hoisting.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figure 1 The illustrated mandrel tooling for assembling a heavy-duty drive axle of a trackless navigation AGV includes a central steel pipe 1, a left-side round steel bar 2, a right-side round steel bar 3, and two axle ends 4. By statistically analyzing the weight and dimensions of the support beams 5 of heavy-duty drive axles over the years, the stress on the mandrel tooling is calculated, thereby selecting appropriate sizes of steel pipes and round steel bars, and adding allowances to meet the requirements for assembling various heavy-duty drive axles.

[0019] The central steel pipe 1 is set horizontally.

[0020] The left round steel 2 is horizontally fixed to the left side of the central steel pipe 1. A left partition block 7 is fixed between the left round steel 2 and the central steel pipe 1, and the central steel pipe 1 and the left round steel 2 are coaxially arranged.

[0021] The right round steel 3 is horizontally fixed to the right side of the central steel pipe 1. A right partition block 8 is fixed between the right round steel 3 and the central steel pipe 1. The outer diameters of the right round steel 3 and the left round steel 2 are the same.

[0022] Both the left partition 7 and the right partition 8 are solid round steel, which can improve the structural stability and safety of the mandrel.

[0023] Furthermore, the lateral length of the left partition 7 is greater than that of the right partition, thus providing a placement margin, making it suitable for the assembly and use of various heavy-duty drive axles. At the same time, it can also prevent the left partition 7 from getting stuck in the center hole of the drive axle support beam 5, improving ease of use.

[0024] Meanwhile, the diameter of the right partition 8 is greater than the diameter of the left partition 7, the diameter of the left partition 7 is equal to the diameter of the shaft head 4, and the diameter of the right partition 8 is slightly smaller than the inner hole of the steering system component 6, so that the spindle and the inner hole adopt a clearance fit to avoid getting stuck in the inner hole.

[0025] The central steel pipe 1 is coaxially arranged with the left round steel 2 and the right round steel 3, and the outer diameter of the central steel pipe 1 is larger than the outer diameter of the left round steel 2.

[0026] A shaft head 4 is provided on both the extension side of the left round steel 2 and the extension side of the right round steel 3, and the outer diameter of the shaft head 4 is larger than the diameter of the left round steel 2.

[0027] A connecting plate 9 is threadedly connected to the center of the extended side of the axle head 4. When the axle head 4 passes through the inner hole of the steering system component 6, the connecting plate 9 can be set on the outside of the steering system component 6 and connected to the axle head 4 with bolts. This enables precise positioning of the steering system component 6 and facilitates the subsequent precise docking and installation of the steering system component 6 and the drive axle support beam 5.

[0028] The drive axle support beam 5 is arranged laterally, and it has a central hole inside, which extends laterally through the entire drive axle support beam 5.

[0029] The steering system component 6 has a C-shaped structure, including a vertical section and two horizontal sections. The vertical section is a support joint, and a transversely arranged inner hole is provided through the middle of it. Between the two horizontal sections, there is a accommodating area to accommodate the extension of the drive axle support beam 5 on both sides of its length.

[0030] This mandrel fixture is simple to manufacture and easy to operate. First, the left side of the mandrel is passed through the center hole of the drive axle support beam 5, and then positioned by the outer center of the two end shafts 4. It is then connected to the inner hole of the support joint of the steering system component 6 in one step, saving time and effort and greatly improving assembly efficiency. At the same time, the mandrel and the inner hole of the steering system component 6 adopt a clearance fit, avoiding the phenomenon that the mandrel fixture itself is stuck in the inner hole and difficult to disassemble. It is not limited by site conditions and facilitates the docking and installation of the heavy-duty drive axle support beam 5 and the steering system component 6, greatly improving assembly efficiency and making operation convenient.

[0031] This structure is safe, reliable, portable, quick to assemble and disassemble, highly adaptable, and simple to manufacture. It effectively overcomes the low assembly efficiency and unstable hoisting connections of heavy-duty drive axles. It avoids the risks of unstable lifting points, difficult connections, and slippage during the process, reducing unnecessary impact damage and ensuring the appearance quality and assembly safety of the drive axle support beam 5. It also protects the lifting equipment and ropes used, while reducing safety hazards during hoisting.

[0032] The working principle of this patent: This mandrel fixture is simple to manufacture and easy to operate. First, align the left side of the mandrel with the center hole of the drive axle support beam 5 and pass it through the center hole until the right partition 8 is just locked at the right end of the center hole of the drive axle support beam 5. At this time, the left partition 7 is in the left end of the center hole of the drive axle support beam 5. Then, hoist the steering system component 6 and align the mandrel fixture's shaft end with and insert it into the inner hole of the steering system component 6. Then, connect the steering system component 6 to the shaft end 4 on the outside using the connecting plate 9 and bolts. This achieves positioning through the outer center of the two shaft ends 4, completing the process in one step, saving time and effort, and greatly improving assembly efficiency. At the same time, the mandrel and the inner hole of the steering system component 6 adopt a clearance fit, avoiding the phenomenon that the mandrel fixture itself is stuck in the inner hole and difficult to disassemble, and is not limited by site conditions.
