Description

Technical Field

[0001] This utility model belongs to the field of assembly and flipping tooling technology, and in particular relates to an assembly and flipping tooling for a milling wheel reducer. Background Technology

[0002] In the assembly process of milling wheel reducers, flipping the reducer is a crucial and unavoidable step. However, examining current flipping methods reveals significant drawbacks. Traditional, conventional support methods lack effective buffering and precise positioning mechanisms between the reducer and the support structure during the flipping process, making them highly susceptible to hard collisions. The direct consequence of such collisions is noticeable impact marks on the workpiece surface; in severe cases, this can even affect the internal structure, causing component deformation and damage, ultimately having a significant negative impact on the overall quality and performance of the product.

[0003] Furthermore, the significant friction generated during the flipping process using conventional support methods places a heavy burden on workers. Workers need to exert considerable physical strength to propel the milling wheel reducer, which undoubtedly increases their workload significantly and drastically reduces operational efficiency per unit time. More importantly, in actual operation, the high friction also increases the uncontrollability of the flipping process. In the event of an accident, worker safety will be seriously threatened, and it is also difficult to ensure the integrity of the workpiece throughout the flipping process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a milling wheel reducer assembly and flipping fixture, which can protect the workpiece from collisions and damage during flipping. By using bearings to reduce friction, the milling wheel reducer can be flipped efficiently and easily. This fixture can reduce the labor intensity of workers, improve production efficiency, and ensure worker safety and prevent damage to the workpiece.

[0032] Example 1

[0033] like Figures 1-2 As shown, this utility model embodiment provides a milling wheel reducer assembly and flipping fixture, including a support component 4, a load-bearing component, and a clamp 5. The support component 4 includes support legs distributed on both sides and a crossbeam 403 fixed on the top of the support legs on both sides. A support plate 3 is installed above the crossbeam 403. The load-bearing component includes bearing seats 1 set at the front and rear of the support plate 3. The bearing seats 1 are movably connected to the support plate 3 through a spacing adjustment mechanism. Bearings 2 are assembled inside the bearing seats 1. The clamp 5 includes a connecting pipe 502 and clamping plates 501 symmetrically arranged on both sides of the connecting pipe 502. The clamping plates 501 are provided with mounting holes 503 for fixing the milling wheel reducer 6. The two ends of the connecting pipe 502 away from the clamping plate 501 are respectively inserted into the inner rings of the bearings 2 on both sides and are interference-fitted with them.

[0034] This invention uses a support component as the main support structure, providing stable and reliable support for the milling wheel reducer during its rotation. The adjustable bearing housing adapts to the assembly requirements of different specifications of milling wheel reducers, improving the tooling's versatility. The interference fit between the clamp and the bearing ensures stable and reliable rotation, significantly reducing friction during the process. The precise positioning design of the mounting holes and the reducer simplifies the assembly process and reduces operational difficulty. This tooling combines structural stability, ease of operation, and functional expandability, effectively improving assembly efficiency, reducing workpiece damage, and extending equipment lifespan.

[0035] Example 2

[0036] like Figures 1-2 The present invention provides a milling wheel reducer assembly tilting fixture, which exists in pairs on both sides of the milling wheel reducer 6. The fixture includes a support assembly 4, a load-bearing assembly, and a clamp 5. The support assembly 4 is designed to match the weight of the milling wheel reducer to prevent the milling wheel reducer from exceeding its load-bearing capacity. The support assembly 4 includes support legs on both sides and a crossbeam 403. The crossbeam 403 is fixed to the top of the support legs on both sides, and a support plate 3 is welded above the crossbeam 403. The load-bearing assembly includes bearing seats 1 located at the front and rear of the support plate 3, with bearings 2 installed inside the bearing seats 1. The clamp 5 is connected to... The device consists of a pipe 502 and clamping plates 501 welded to both sides of the connecting pipe 502. The clamping plates 501 are 20-40mm thick. Mounting holes 503 for fixing the milling wheel reducer are provided on the clamping device 5. The connecting pipe 502 at the other end of the clamping plate 501 is inserted into the inner ring of the bearings 2 on both sides. The inner ring of the bearings 2 is interference-fitted with the connecting pipe 502. When it is necessary to rotate the milling wheel reducer, the operator only needs to rotate the milling wheel reducer easily and efficiently around the lateral direction within a safe range during overhead crane hoisting, taking advantage of the bearing's friction-reducing characteristics, to successfully complete the rotation operation.

[0037] In this embodiment, as Figure 6 and Figure 8 As shown, the spacing adjustment mechanism includes a plurality of first threaded holes evenly spaced along both sides of the longitudinal direction of the support plate 3. The bearing seat 1 includes a central mounting part for mounting the bearing 2 and extension parts on both sides of the central mounting part. The extension parts are provided with second threaded holes. The bearing seat 1 is movably connected to the support plate 3 by bolts passing through the second threaded holes and the first threaded holes. Specifically, according to the specific dimensional parameters of the milling wheel reducer, the operator uses a special tool to finely adjust the distance between the two bearing seats through the threaded holes on the support plate 3. During the adjustment process, repeated measurements and calibrations are required to ensure that the distance is accurate, thus creating conditions for the subsequent accurate installation of the clamp and the milling wheel reducer.

[0038] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the support leg includes a bottom beam 401 and a vertical beam 402. The vertical beam 402 is located near the bottom beam 401, and a triangular reinforcing rib 404 is provided at the connection between the vertical beam 402 and the bottom beam 401. The thickness of the triangular reinforcing rib 404 is the same as the thickness of the support plate 3. A transverse reinforcing rib 405 is also provided between the vertical beams 402 of the two support legs.

[0039] In this embodiment, the bottom beam 401, vertical beam 402, and longitudinal beam all adopt a box-type structure. Figure 5 Its cross-sectional dimensions are designed to be 200×200mm to 400×400mm according to load-bearing requirements, and the web thickness is 10-20mm.

[0040] In this embodiment, the bottom of the bottom beam 401 is provided with adjustable anchor bolts.

[0041] In this embodiment, the mounting hole 503 is an oblong hole that extends along the length of the clamping plate 501. The clamping plate 501 is fixed to the milling wheel reducer by bolts passing through the oblong hole and the connecting hole on the milling wheel reducer. The length dimension of the oblong hole is 2-5mm larger than the bolt diameter. Figure 7 ).

[0042] In this embodiment, the bearing 2 is a self-aligning roller bearing ( Figure 9 Its rated dynamic load is more than 3 times the weight of the milling wheel reducer.

[0043] The milling wheel reducer assembly and tilting fixture designed in this utility model mainly consists of a support component, a support plate, a load-bearing component, and a clamp. In actual application scenarios, this fixture must be used in pairs to form a stable and efficient tilting operation system.

[0044] This utility model fully considers the diversity of milling wheel reducer weights and has carried out precise matching load-bearing design for the support components. The load-bearing capacity of each support component has been rigorously calculated and tested, which can accurately match milling wheel reducers of different weight specifications, thereby effectively avoiding the risk of the milling wheel reducer weight exceeding the load-bearing limit of the support leg, and comprehensively ensuring the stability and safety of the tooling during use.

[0045] The support plate of this utility model is fixed in the middle of the crossbeam by a high-strength welding process. The support plate is precision machined and has multiple threaded holes. These threaded holes are like the "adjustment hub" of the tooling. With their help, the operator can flexibly and accurately adjust the distance between the two bearing seats according to the specific size of the milling wheel reducer. After adjusting to the appropriate position, the bearing seats are firmly assembled onto the support seat using high-strength bolts, and high-performance bearings are precisely embedded inside the bearing seats, laying the foundation for subsequent low-friction flipping operations.

[0046] The clamp of this invention is assembled from two identical plates and a connecting pipe within the clamp using a sophisticated welding process. Specific mounting holes are formed on the clamp according to the distribution of the milling wheel reducer's fixing points. Through these mounting holes, bolts can be used to tightly connect the clamp to the milling wheel reducer, effectively restricting the milling wheel reducer's five degrees of freedom, retaining only the single degree of freedom of lateral rotation. The connecting pipe within the clamp is cleverly embedded in a bearing. Thanks to the bearing's extremely low coefficient of friction, during actual operation, the operator only needs to apply minimal external force to easily and smoothly achieve lateral rotation of the milling wheel reducer.

[0047] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
