Description

Technical Field

[0001] The utility model belongs to the technical field of bearing manufacturing equipment, and particularly relates to an inner and outer ring combination mechanism for bearing production. Background Art

[0002] A bearing is a component used to reduce the friction coefficient during the movement of a mechanical rotating body and bear loads. As a type of rolling bearing, it usually includes an outer ring, an inner ring, balls, and a cage, which can reduce the friction during power transmission in a rolling manner and improve the transmission efficiency of mechanical power.

[0003] In the prior art, during the assembly of a bearing, the inner and outer rings are usually combined first, then balls are filled in the gap between the two, and finally cages are installed on both sides of each ball. Regarding the combination of the inner and outer rings, that is, placing the inner ring inside the outer ring, the mechanism adopted can be seen in the patent number: CN202410183588.2; the invention name is: A precision bearing automatic assembly device and assembly method. As the bottom conveying mechanism passes by, the outer ring feeding mechanism and the inner ring feeding mechanism arranged above it in sequence release one outer ring and one inner ring in sequence. The outer ring and the inner ring respectively fall on the conveying mechanism and form a combination. This combination method requires workers to continuously supplement the outer and inner rings into their respective corresponding hoppers (both the outer ring feeding mechanism and the inner ring feeding mechanism have hoppers), which involves the previous cleaning and drying work of the outer and inner rings. This method will increase labor costs and has poor adaptability. In addition, the outer and inner rings fall on the conveying mechanism in a dropping manner, which will increase the risk of bumping and surface scratching to a certain extent and affect the final product quality.

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0038] Please refer to Figure 1 and Figure 2 together, and now the inner and outer ring combination mechanism for bearing production provided by the present utility model will be described.

[0039] Regarding the current situation, extrusion rods are provided at the bottom of the hopper. The extrusion rods are opened to realize the falling of the inner ring or the outer ring. However, during the opening process of the extrusion rods, it is also impossible to ensure that the inner ring or the outer ring is horizontally arranged during the falling process. When the inner ring or the outer ring is inclined, the risk of scratching will increase.

[0040] In response to this, the inner and outer ring combination mechanism for bearing production includes a support frame 10, an intermediate base 20, a loading plate 30, a pushing structure 40 and a lifting structure 50. The support frame 10 has a horizontally arranged lower sliding plane. The intermediate base 20 is fixedly arranged on the lower sliding plane, and an assembly table 21 is provided on the top of the intermediate base 20. The intermediate base 20 divides the lower sliding plane into a left sliding surface 11 and a right sliding surface 12. A material channel 22 communicating with the left sliding surface 11 and the right sliding surface 12 is provided on the intermediate base 20, and a through hole 23 communicating with the assembly table 21 is provided at the top of the material channel 22. The loading plate 30 is fixedly arranged on the support frame 10 and is located above the right sliding surface 12. The top end surface of the loading plate 30 is flush with the assembly table 21. The pushing structure 40 can push the inner ring on the left sliding surface 11 into the material channel 22 and at the same time push the outer ring on the loading plate 30 onto the assembly table 21. The lifting structure 50 is arranged below the material channel 22 and can push the inner ring in the material channel 22 through the through hole 23 onto the assembly table 21.

[0041] The inner and outer ring combination mechanism for bearing production provided in this embodiment, compared with the prior art, the combination of the support frame 10, the intermediate base 20 and the material loading plate 30 forms a left sliding surface 11 for the inner ring to slide. At the same time, the material loading plate 30 on the right sliding surface 12 allows the outer ring to slide. Through the material pushing structure 40, the inner ring can be pushed into the material channel 22, and at the same time, the outer ring can be pushed onto the assembly table 21. Subsequently, the inner ring in the material channel 22 is pushed upward by the material ejecting structure 50. By pushing the inner ring upward, it can enter the outer ring after passing through the through hole 23, which can effectively avoid damage caused by dropping, ensure the final product quality, and has strong practicability. At the same time, the seat sliding surface and the material loading plate 30 have a certain area, which is convenient for the feeding work of the inner ring or the outer ring, and is more suitable for production lines with processes such as cleaning and drying, and has strong adaptability.

[0042] In some embodiments, the above-mentioned through hole 23 can adopt a structure as Figure 2 shown. Refer to Figure 2 , the aperture of the through hole 23 is larger than the outer diameter of the inner ring, and the aperture of the through hole 23 is smaller than the inner diameter of the outer ring.

[0043] This structure can ensure that the inner ring can smoothly pass through the through hole 23, and at the same time, it can also ensure that the outer ring can be smoothly and stably placed on the assembly platform, which is convenient for the combination work of the inner ring and the outer ring.

[0044] In some embodiments, the above-mentioned material pushing structure 40 can adopt a structure as Figures 1 to 3 shown. Refer to Figures 1 to 3 , the material pushing structure 40 includes a guide rod 41, a fixed vertical plate 42, a first push plate 43, a second push plate 44 and a first telescopic structure 45. There are two guide rods 41, and the two guide rods 41 are arranged on the support frame 10 along the through direction of the material channel 22, and both guide rods 41 are located above the intermediate base 20. The fixed vertical plate 42 is fixed on the two guide rods 41, and the fixed vertical plate 42 is located above the intermediate base 20. The first push plate 43 is located above the left sliding surface 11 and is slidably connected to each guide rod 41. The first push plate 43 is provided with a first lower push block 431 corresponding to the material channel 22. The second push plate 44 is located above the material loading plate 30 and is slidably connected to each guide rod 41. The second push plate 44 is provided with a first upper push block 441 corresponding to the assembly table 21. There are two first telescopic structures 45, and each first telescopic structure 45 is arranged on the fixed vertical plate 42 and corresponds to the first push plate 43 and the second push plate 44 respectively. The two first telescopic structures 45 can drive the first push plate 43 and the second push plate 44 to move relatively or move away from each other.

[0045] The fixed vertical plate 42 is fixedly arranged on two guide rods 41, which can ensure to provide a fixed installation position and facilitate the installation of two first telescopic structures 45. The two first telescopic structures 45 can drive the first push plate 43 and the second push plate 44 to move relatively or away from each other on each guide rod 41 respectively, so as to push the inner ring into the material channel 22 and at the same time push the outer ring onto the assembly table 21, facilitating the combination of the inner ring and the outer ring.

[0046] Since the material channel 22 has a certain length and the first push plate 43 cannot enter the material channel 22, the inner ring can be pushed by the first lower push block 431 on the first push plate 43 at this time. Similarly, the outer ring can be pushed by the first upper push block 441 on the second push plate 44 to ensure that after the inner ring enters the material channel 22, it can correspond to the inner hole of the outer ring, facilitating the subsequent combination work.

[0047] Preferably, the fixed vertical plate 42 is located at the middle position of the guide rod 41 and at the middle position of the middle base 20 along the length direction of the guide rod 41. At this time, the telescopic amounts of the two first telescopic structures 45 can be kept consistent, so as to ensure that the inner ring and the outer ring are centered on the middle base 20.

[0048] V-shaped notches are arranged at the extending ends of the first lower push block 431 and the first upper push block 441 to ensure the limit of the inner ring and the outer ring and the effect of pushing the material.

[0049] In some embodiments, the above-mentioned first telescopic structure 45 can adopt the structure as shown in Figure 1 and Figure 3 . Refer to Figure 1 and Figure 3 . The two first telescopic structures 45 are both arranged along the through direction of the material channel 22, and the two first telescopic structures 45 are arranged in a staggered manner. This structure can avoid interference between the two first telescopic structures 45, thus ensuring the utilization rate of space.

[0050] In some embodiments, the above-mentioned first push plate 43 can adopt the structure as shown in Figure 2 . Refer to Figure 2 . The first push plate 43 is also provided with a second upper push block 432 corresponding to the first upper push block 441.

[0051] The second upper push block 432 corresponds to the first upper push block 441. After they move relatively, they can clamp and limit the outer ring on the assembly table 21, so as to realize the positioning of the outer ring and avoid the outer ring from disengaging from the assembly table 21 due to the inertial force.

[0052] The extending end of the second upper push block 432 can be provided with a V-shaped notch.

[0053] In some embodiments, the above-mentioned material pushing structure 40 can adopt the structure as shown in Figures 1 to 2The structure shown. Refer to Figures 1 to 2 , a long strip sliding opening is provided on the material loading plate 30, and the length direction of the long strip sliding opening is arranged along the through direction of the material channel 22.

[0054] The material pushing structure 40 further includes an auxiliary plate 46. The auxiliary plate 46 is located between the material loading plate 30 and the right sliding surface 12, and is fixedly connected to the second pushing plate 44 through a connecting column passing through the long strip sliding opening. A second lower pushing block 461 corresponding to the first lower pushing block 431 is provided on the auxiliary plate 46.

[0055] The auxiliary plate 46 can move synchronously with the second pushing plate 44. The second lower pushing block 461 corresponds to the first lower pushing block 431. After the two move relatively, the inner ring in the material channel 22 can be clamped and limited, thereby realizing the positioning of the inner ring and preventing the inner ring from separating from the through hole 23 due to inertia force.

[0056] The setting of the long strip sliding opening can mainly ensure the connection between the second pushing plate 44 and the auxiliary plate 46 through the connecting column. Multiple long strip sliding openings can be provided, thereby correspondingly reducing the width of each long strip sliding opening and avoiding affecting the movement of the outer ring.

[0057] A V-shaped notch can be provided at the extended end of the first lower pushing block 431.

[0058] In some embodiments, the above-mentioned material ejecting structure 50 can adopt the structure as Figure 2 shown. Refer to Figure 2 , the material ejecting structure 50 includes a top plate 51 and a second telescopic structure 52. The top plate 51 is arranged in the accommodating hole at the bottom of the material channel 22. The second telescopic structure 52 is arranged on the support frame 10 along the vertical direction and is located below the sliding plane, and can push the top plate 51 to move up and down.

[0059] The top plate 51 can move up and down under the drive of the second telescopic structure 52, thereby sending the inner ring onto the assembly table 21 and enabling the inner ring to enter the inner hole of the outer ring to achieve combination.

[0060] It should be noted that when the top plate 51 is in the accommodating hole, the top surface height thereof is flush with the left sliding surface 11, and after the inner ring is pushed onto the assembly table 21, the top surface height is flush with the height of the assembly table 21.

[0061] In some embodiments, the above-mentioned top plate 51 can adopt the structure as Figure 1 shown. Refer to Figure 1 , the top plate 51 is a circular plate, and the diameter of the top plate 51 is larger than the outer diameter of the inner ring.

[0062] The circular plate can facilitate adapting to the shape of the inner ring, while ensuring the support of the inner ring and being convenient for manufacturing.

[0063] As a working mode implementation of the present utility model, reference can be made to Figure 3 , which relates to the adaptability of the inner and outer ring combination mechanism for bearing production provided by the present utility model, that is, the inner and outer rings need to be cleaned before combination, and quality inspection is also required. Only after quality inspection can assembly be carried out. Before combination, there are two corresponding conveyor lines for conveying the inner and outer rings respectively. Therefore, the left sliding surface 11 and the loading plate 30 can respectively correspond to the two conveyor lines. Specifically, the inner ring can be transferred to the left sliding surface 11 through the mechanical pushing structure 60, and at the same time, the outer ring can be transferred to the loading plate 30. Regarding the combination of the inner and outer rings on the assembly table 21, the two can be horizontally pushed out of the assembly table 21 through the mechanical pushing structure 60 located on one side of the middle base 20 and enter the next process.

[0064] Regarding the mechanical pushing structure 60, it can ensure the cylinder and the pushing end head connected to the telescopic end of the cylinder.

[0065] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
