Description

Technical Field

[0001] This utility model relates to the field of bearing assembly tooling, and in particular to a bearing assembly inner ring flow tooling. Background Technology

[0002] In the assembly process of bearing manufacturing, the inner ring, as the core component that directly bears the rolling elements, has its assembly accuracy directly affecting the bearing's rotational stability and fatigue life. Traditional inner ring assembly processes suffer from the following technical bottlenecks:

[0003] (i) Limited Precision of Manual Assembly: Existing production lines largely rely on manual pre-assembly of the inner ring and rolling elements, requiring operators to visually judge the fit clearance based on experience. Since the inner ring raceway diameter tolerance zone typically needs to be precisely controlled within the error range, manual adjustments result in significant error fluctuations. However, the pass rate for manual assembly clearance is difficult to consistently meet the assembly requirements of precision bearings. Furthermore, the repeated manual adjustments easily cause surface scratches, making it difficult to meet the surface roughness requirements of the inner ring raceway. This leads to an increased rework rate.

[0004] (ii) Low equipment coordination efficiency: Traditional inner ring processing lines adopt a single-machine operation mode, which is prone to elastic deformation during manual handling, and the roundness error increases with each transfer. The independent operation of multiple machines results in a long average waiting time, and special tooling is required for repeated positioning, which increases the cycle of single assembly.

[0005] (iii) Lagging quality inspection: The existing process only performs final inspection after assembly, and cannot obtain key parameters of the inner ring in real time. When deviations occur, the entire assembly needs to be disassembled and reworked, resulting in the scrapping of related components such as rolling elements, which increases the overall cost loss rate.

Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance.

[0032] Please see Figures 1 to 5The bearing assembly inner ring assembly tooling of this embodiment includes a feeding assembly 1, which supplies the inner ring. Specifically, the feeding assembly 1 includes a first motor 11, a first rotating shaft 12, and a guide plate 13. The first motor 11 is coupled to the first rotating shaft 12, driving the first rotating shaft 12 to rotate. The first rotating shaft 12 also passes through the guide plate 13. The feeding assembly 1 also includes a first bracket 14, which is evenly distributed and connected at one end to the guide plate 13, thereby providing support for the guide plate 13.

[0033] The feeding assembly 1 further includes a first fixed plate 15, a second fixed plate 16, and a support rod 17. The two ends of the support rod 17 are respectively connected to the first fixed plate 15 and the second fixed plate 16 to support the first fixed plate 15 and the second fixed plate 16, forming a space for placing multiple strings of inner rings. A first rotating shaft 12 passes through and is connected to the first fixed plate 15, and the first fixed plate 15 abuts against the guide plate 13, and the first fixed plate 15 is rotatable relative to the guide plate 13 under the action of the first rotating shaft 12.

[0034] The tooling also includes a conveying assembly 2, which includes a first conveying section 21 and a second conveying section 22. The first conveying section 21 cooperates with the feeding assembly 1 to initially convey the inner ring, and the second conveying section 22 cooperates with the first conveying section 21 to transport the initially conveyed inner ring again.

[0035] Specifically, the first conveying unit 21 includes a second support 211, a chute 212, and a slider 213. The second support 211 is evenly connected to the chute 212, thereby supporting the chute 212. The slider 213 is slidably disposed within the chute 212. The first conveying unit 21 also includes a third support 214, a first cylinder 215, and a push rod 216. The third support 214 is evenly connected to the first cylinder 215, thereby supporting the first cylinder 215. The push rod 216 is movably disposed within the first cylinder 215, and one end of the push rod 216 is also connected to the slider 213. Under the action of the first cylinder 215, the push rod 216 pushes out or pulls back the slider 213. The slide groove 212 is provided with a protrusion 2121 at the end away from the push rod 216. When the slider 213 pushes the inner ring to the end of the slide groove 212, the protrusion 2121 is used to limit the displacement of the inner ring pushed out by the slider 213 so as to facilitate the function of the second conveying part 22.

[0036] Furthermore, a first hole 131 is formed on the surface of the aforementioned guide plate 13. The first hole 131 connects to the slide groove 212 along a first direction. In this embodiment, the first direction is the direction perpendicular to the worktable 5. Figure 2 , Figure 3 The vertical direction is shown. The surface of the first fixing plate 15 has six evenly spaced second holes 151. These second holes 151 connect to the slide groove 212 via the first hole 131 along the first direction. The push rod 216 is configured to pull back the slider 213 each time, allowing the inner rings to fall sequentially into the slide groove 212 under gravity. When the push rod 216 pushes out the slider 213, it acts on the inner rings that have fallen into the slide groove 212. The second fixing plate 16 has second holes 151 corresponding to the first fixing plate 15. The second fixing plate 16 also has slots 161 that connect to the corresponding second holes 151, facilitating the replacement of the inner rings and ensuring uninterrupted supply from the feeding assembly 1. Preferably, the feeding assembly 1 can be configured with a sensor to detect whether the inner ring between the first fixed plate 15 and the second fixed plate 16 is exhausted. If it is exhausted, the rotation of the first fixed plate 15 will connect another string of inner rings through the second hole 151 to the first hole 131 for continuous supply.

[0037] The second conveying unit 22 includes a fourth support 221 and a fifth support 222, with the fifth support 222 disposed between the fourth supports 221. In this embodiment, two fourth supports 221 are provided, and a track 2221 is also provided on the surface of the fifth support 222. The second conveying unit 22 also includes two clamping assemblies 223, each clamping assembly 223 including a connector 2231. One end of the connector 2231 is movably disposed on the track 2221, meaning that the two clamping assemblies 223 can move relative to the fifth support 222.

[0038] Furthermore, the assembly also includes a fixed block 2232, a movable block 2233, and a second cylinder 2234. One end of the connector 2231 is connected to the fixed block 2232, and the second cylinder 2234 passes through the fixed block 2232 and acts on the movable block 2233 at one end. The movable block 2233 is driven to move up and down by the second cylinder 2234. The gripping assembly 223 also includes grippers 2235 symmetrically arranged on the movable block 2233 and movable relative to the movable block 2233. In this embodiment, two grippers 2235 are provided at both ends of the movable block 2233. Similarly, with the design of the connector 2231 and the track 2221, the grippers 2235 adopt a track-type design and can move closer or further away from each other synchronously, thereby realizing the gripping or releasing of the inner ring.

[0039] The tooling also includes a first transfer component 3, which includes a first transfer section 31 and a calibration section 32. The calibration section 32 acts on the first transfer section 31 to detect the inner ring on the first transfer section 31. The tooling also includes a second transfer component 4, which includes a second transfer section 41 and a storage section 42. The storage section 42 acts on the second transfer section 41 to photograph and store the inner ring on the second transfer section 41. The second conveying section 22 is configured to act on both the first transfer section 31 and the second transfer section 41 simultaneously, that is, the clamping component 223 is configured to act on both the first transfer section 31 and the second transfer section 41 simultaneously, thereby transferring the inner ring that has passed the detection in the first transfer section 31 to the second transfer section 41 for further transfer and assembly.

[0040] Specifically, the first transfer unit 31 includes a first platform 311, a second rotating shaft 312, and a second motor 313. One end of the second rotating shaft 312 is connected to the first platform 311, and the other end is connected to the second motor 313. The second motor 313 drives the second rotating shaft 312 to rotate, causing the first platform 311 to rotate. A first protrusion 314 is provided on the surface of the first platform 311. The calibration unit 32 includes a sixth bracket 321, a third cylinder 322, and a quality inspection piece 323. The third cylinder 322 passes through the sixth bracket 321 and one end is connected to the quality inspection piece 323. The third cylinder 322 pushes the quality inspection piece 323 to perform quality inspection on the inner ring on the first protrusion 314 to ensure the pass rate of the assembled inner ring. Preferably, in this embodiment, two first protrusions 314 are provided. One first protrusion 314 is used to be transferred by the gripping component 223, and the other first protrusion 314 is used to be detected by the quality inspection piece 323. Thus, they work alternately under the rotation of the first platform 311 to improve efficiency.

[0041] Furthermore, the second transfer unit 41 includes a second platform 411, a third rotating shaft 412, and a third motor 413. One end of the third rotating shaft 412 is connected to the second platform 411, and the other end is connected to the third motor 413. A second protrusion 414 is provided on the surface of the second platform 411. The third rotating shaft 412 is driven to rotate by the third motor 413, thereby causing the second platform 411 to rotate. The second protrusion 414 is used to place and perform calibration on the inner ring. The storage unit 42 includes a seventh bracket 421 and a camera 422. The camera 422 is connected to the seventh bracket 421, and the camera 422 acts on the inner ring on the second protrusion 414 to capture and store images.

[0042] Furthermore, the feeding component 1, the conveying component 2, the first transfer component 3, and the second transfer component 4 are all mounted on the workbench 5 for automated construction operations.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
