Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, and in particular to a continuous tooling for filling bearing rolling elements. Background Technology

[0002] As a core component of mechanical transmission systems, the manufacturing precision of bearings directly affects the operational stability and service life of equipment. In the bearing assembly process, the filling process of rolling elements, such as steel balls and rollers, is a crucial step in determining the uniformity of bearing clearance. Traditional production methods mainly suffer from the following technical bottlenecks:

[0003] (i) High dependence on manual labor: Conventional processes require operators to manually align the cage with the outer and inner rings before filling the rolling elements one by one. This method is not only labor-intensive, but also prone to quality problems such as omissions and misalignments due to visual fatigue, resulting in a high defect rate in the manual filling process.

[0004] (ii) Limitations of semi-automatic equipment: Most existing semi-automatic ball filling machines use fixed tooling, requiring manual loading and unloading and frequent adjustment of positioning fixtures, which makes it difficult to adapt to the needs of flexible production of multiple varieties.

The advantages and features of this utility model will become clearer from the following description.

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 for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance.

[0026] Please see Figures 1 to 4 This embodiment describes a continuous assembly tooling for filling bearing rolling elements. The tooling includes an assembly section 1, which sequentially assembles the inner ring, outer ring, and rolling elements of the bearing. Specifically, the assembly section 1 includes a rotatable turntable 11 and positioning elements 12 evenly distributed on the turntable 11. In this embodiment, five positioning elements 12 are provided on the surface of the turntable 11. The tooling also includes two transfer mechanisms 2, a filling section 3, a correction section 4, and a transfer mechanism 2 acting sequentially on the same positioning element 12, forming a cycle. Preferably, the two transfer mechanisms 2 sequentially transfer the inner ring and the outer ring, and the transfer mechanism 2 transfers the bearing with assembled inner and outer rings and rolling elements into a cage. The filling section 3 fills the rolling elements, and the correction section 4 ensures the accuracy of the assembly of the inner and outer rings and rolling elements. The assembly section 1 also includes a motor 13 and a rotating shaft 14. One end of the rotating shaft 14 is engaged with the motor 13, and the other end of the rotating shaft 14 is connected to the turntable 11. That is, the rotating shaft 14 is driven to rotate by the motor 13, which in turn drives the turntable 11 to rotate, so as to realize the assembly and transfer of the inner ring, outer ring and rolling elements in a continuous operation.

[0027] The transfer mechanism 2 includes a support member 21 and a crossbar 22 connected to the support member 21. A first track 221 is provided on the surface of the crossbar 22. The transfer mechanism 2 also includes a clamping assembly 23 disposed on the first track 221. In this embodiment, one clamping assembly 23 is configured in each transfer mechanism 2. The clamping assembly 23 includes a connector 231 and a fixing block 232. The connector 231 is movably fitted to the first track 221, and one end of the connector 231 is connected to the fixing block 232. Furthermore, the gripping assembly 23 also includes a movable block 233, a first cylinder 234, and grippers 235. The first cylinder 234 passes through the fixed block 232 and acts on the movable block 233 at one end, driving the movable block 233 to move up and down. The grippers 235 are symmetrically arranged on the movable block 233 and are movable relative to the movable block 233. Preferably, similar to the design of the connector 231 and the first track 221, the grippers 235 and the movable block 233 adopt a track-type design, which can move closer or further away from each other synchronously, thereby realizing the gripping or releasing of the outer or inner ring.

[0028] The filling part 3 includes a clamping assembly 31, which includes a first frame 311, a storage tank 312, and a guide tube 313. The storage tank 312 is connected to one end of the first frame 311 and is fixed by the first frame 311. The storage tank 312 is used to hold the rolling element. One end of the guide tube 313 is connected to the storage tank 312, and the rolling element in the storage tank 312 is conveyed through the guide tube 313.

[0029] Furthermore, the filling part 3 also includes a control component 32, which includes a second cylinder 321, a first wedge 322, and a second wedge 323. The second cylinder 321 passes through the first frame 311 and is connected to the first wedge 322. The second cylinder 321 drives the first wedge 322 to move up and down. A first inclined surface 3221 is provided at the end of the first wedge 322 near the second wedge 323, and a second inclined surface 3231 is provided at the end of the second wedge 323 near the first wedge 322. The first inclined surface 3221 cooperates with the second inclined surface 3231. Figure 1 and Figure 4 As shown, when the first wedge 322 is lowered by the second cylinder 321, the second wedge 323 moves to the left under the action of the first inclined surface 3221 and the second inclined surface 3231.

[0030] Furthermore, a second track 3232 is provided on the surface of the second wedge 323, and one end of the guide tube 313 is also provided on the second track 3232 and connected to the second wedge 323 through the second track 3232, such as... Figure 4 As shown, the second track 3232 can be partially designed as a recessed structure with a snap-fit ​​function. Through optimized design of the connection end between the guide tube 313 and the second track 3232, such as a protruding structure at the connection end to match the recessed structure of the second track 3232, a snap-fit ​​effect is achieved. The second wedge 323 also has a through hole 3233 within the second track 3232. When the second wedge 323 is moved by the first wedge 322, and when the through hole 3233 connects with the guide tube 313, the rolling element can fall into the assembled inner and outer rings through the through hole 3233.

[0031] Furthermore, the control component 32 also includes a limiting rod 324 and an elastic element 325. The limiting rod 324 is connected to the storage tank 312, one end of the elastic element 325 is connected to the limiting rod 324, and the other end of the elastic element 325 is connected to the end of the second wedge 323 away from the first wedge 322. The control component 32 also includes a sensor 326, which is disposed on the second wedge 323 and electrically coupled to the second cylinder 321.

[0032] Specifically, when the second cylinder 321 pushes the first wedge 322 down, it pushes the second wedge 323 to move, so that the guide tube 313 connects with the through hole 3233 to fill the rolling element. At this time, the second wedge 323 compresses the elastic element 325, and the sensor 326 uses known photoelectric counting technology to detect the number of rolling elements falling through the through hole 3233. When the set number is met, the second cylinder 321 is raised through the electrical cooperation between the sensor 326 and the second cylinder 321. Then, under the elastic action of the elastic element 325, it recovers and the second wedge 323 moves again to disconnect the connection between the guide tube 313 and the through hole 3233. At this time, the rolling elements in the storage tank 312 are no longer filled.

[0033] The correction unit 4 includes a pressing assembly 41 and a pushing assembly 42. The pressing assembly 41 includes a second frame 411, a third cylinder 412, and a pressing block 413. The third cylinder 412 passes through the second frame 411 and is connected at one end to the pressing block 413. The third cylinder 412 acts on the pressing block 413 to press against the assembled inner and outer rings and rolling elements. The pushing assembly 42 includes a third frame 421, a fourth cylinder 422, and a pushing block 423. The fourth cylinder 422 is disposed on the third frame 421 and is connected at one end to the pushing block 423. The pushing of the fourth cylinder 422 causes the pushing block 423 to act on the outer ring. Thus, under the synchronous action of the pressing block 413 and the pushing block 423, the conformity of the assembled inner and outer rings and rolling elements is ensured. Finally, the assembly cage is transferred again by the transfer mechanism 2.

[0034] The tooling also includes a workbench 5, on which the assembly part 1, the transfer mechanism 2, the filling part 3, and the correction part 4 are all disposed for assembly line operation.

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.

[0036] 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. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
