Description

Technical Field

[0001] The utility model belongs to the technical field of bearing production equipment, and particularly relates to a centrifugal dryer for bearing production. Background Art

[0002] A bearing is composed of an outer ring, an inner ring, balls and a cage. In order to reduce the friction of the bearing rolling elements and extend the service life of the bearing, during the bearing production process, it is necessary to perform an oiling process on the bearing to increase its rust prevention ability and thus extend the service life of the bearing. However, after oil immersion, it is also necessary to dry the oil adhering to the bearing surface, and a centrifugal dryer is required for this process.

[0003] In the prior art, for a centrifugal dryer for bearings, reference can be made to the patent number: CN202321174566.7; the patent name is: A Bearing Centrifugal Drying Device. This device dries the bearings by rotation. Specifically, a rotatable body is provided in the centrifugal drying box, and a plurality of card slots are annularly and spacedly provided on the outer edge of the rotatable body. The bearings can be pushed into or out of each card slot by translating through the openings on both sides at the top of the centrifugal drying box. However, the size of the card slots is larger than that of the bearings. Therefore, after the bearings enter the card slots and rotate with the rotatable body, the multiple bearings in each card slot usually collide with each other under the action of vibration or rub against the inner wall of the centrifugal drying box, resulting in wear on the bearing surface and affecting the product quality. Summary of the Utility Model

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, 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.

[0039] Please refer to Figure 1 and Figure 2 simultaneously, and now the centrifugal dryer for bearing production provided by the present utility model will be described. The centrifugal dryer for bearing production includes a drying box 10, a rotating tube 20, a carrier 30, a fixing component 40 and a driver 50. The drying box 10 has a drying cavity 11, and a notch 12 penetrating in the horizontal direction is provided at the top of the drying box 10. The rotating tube 20 is horizontally rotatably arranged on the drying box 10 and extends out at both ends. The axial direction of the rotating tube 20 is arranged in the same direction as the extending direction of the notch 12. A plurality of carriers 30 are provided, and each carrier 30 is located in the drying cavity 11 and is annularly spaced around the axis of the rotating tube 20. Each carrier 30 is fixedly connected to the rotating tube 20, and a limiting card slot 33 that can correspond to the notch 12 and penetrates along the extending direction of the notch 12 is provided at the extending end of each carrier 30. The fixing component 40 is connected to one end of the rotating tube 20 and has a plurality of pressing parts respectively located on the ground of each limiting card slot 33. The fixing component 40 can fix the bearings in each limiting card slot 33 through each pressing part when the rotating tube 20 rotates. The driver 50 is fixedly arranged on the drying box 10 and is power-connected to the other end of the rotating tube 20.

[0040] Compared with the prior art, the centrifugal dryer for bearing production provided by this embodiment has the drying cavity 11 provided by the drying box 10, which can ensure that the drying work is carried out in a closed environment, thereby ensuring the cleanliness of the drying work. The combination of the rotating tube 20 and the carrier 30 can provide a clamping space for the bearings through a plurality of limiting card slots 33, and during the rotation, the oil attached to the bearings is thrown into the drying cavity 11 by the action of centrifugal force. In addition, a fixing component 40 is provided, which can fix each bearing in the corresponding limiting card slot 33 before starting the drying, avoiding mutual collision and mutual friction of the bearings during the drying work, ensuring the final product quality, and having strong practicability.

[0041] It should be noted that the drying box 10 is usually arranged in the production line of the bearing, and is equipped with a toggle structure, which can ensure that the bearing enters the limit slot 33, and can also facilitate the bearing to slide out of the limit slot 33, and can also cover the notch 12. In addition, a liquid outlet connected to the drying chamber 11 is provided at the bottom of the drying box 10 to ensure the timely discharge of the oil. This technology is all existing technology and will not be repeated here.

[0042] In some embodiments, the notch 12 may be formed as follows: Figure 2 See the structure shown. Figure 2 A feed plate is provided at one end of the notch 12, and a discharge plate is provided at the other end of the notch 12.

[0043] Among them, the upper plate surfaces of the feed plate and the discharge plate are both arranged flush with the bottom surface of the card slot rotated upward.

[0044] The feed plate and the discharge plate are flush with the bottom surface of each limit slot 33 rotated upward, which can ensure that each bearing can slide smoothly into each limit slot 33, or slide out of each limit slot 33, thereby ensuring the smooth passage of the bearing and ensuring the continuity of production to a certain extent.

[0045] In some embodiments, the rotating tube 20 may be Figure 1 See the structure shown. Figure 1 The end of the rotating tube 20 connected to the driver 50 is provided with a sealing plug 21. This structure can ensure that only one end of the rotating tube 20 is open, thereby ensuring the connection with the driver 50 and also ensuring the connection with the fixing component 40.

[0046] In some embodiments, the support frame 30 may be configured as follows: Figure 1 See the structure shown. Figure 1 Each carrier 30 includes a support tube 31 and a fixing seat 32. Two support tubes 31 are provided, and the two support tubes 31 are arranged at intervals along the axial direction of the rotating tube 20, and one end of each support tube 31 is connected to the rotating tube 20, and the other end extends radially along the rotating tube 20. The fixing seat 32 is arranged along the axial direction of each rotating tube 20 and is fixedly connected to the extended end of each support tube 31. The limiting slot 33 is located at the end of the fixing seat 32 away from each support tube 31.

[0047] The support tube 31 can reduce the weight and ensure stable connection to the fixing seat 32, and the fixing seat 32 can correspond to the notch 12 and facilitate the opening of the limit slot 33. In addition, the weight of this structure is relatively small and the energy saving effect is good.

[0048] For the limit slot 33, see Figure 3, the fixing base 32 can have a cuboid-shaped outer structure. Specifically, first, a groove with a rectangular cross-section is formed on the fixing base 32, and then limiting strips are fixedly connected to the tops of the two side walls of the groove. The distance between the two limiting strips needs to be smaller than the outer diameter of the bearing.

[0049] In some embodiments, the above-mentioned fixing assembly 40 can adopt the structure as Figure 1 shown. Refer to Figure 1 , the fixing assembly 40 includes a sleeve 41, an air pump 43, and a sliding structure 44. The sleeve 41 is fixedly arranged on the drying box 10, is coaxially arranged with the rotating tube 20, and is rotatably connected to the end of the rotating tube 20 extending out of the drying cavity 11 through a sealing bearing 42. The air pump 43 is connected to the sleeve 41 through an air pipeline. A plurality of sliding structures 44 are provided, and each sliding structure 44 is arranged on each fixing base 32 one by one and is connected to each support cylinder 31 corresponding to each fixing base 32, and can fix the bearing in the clamping groove after the air pump 43 inflates the rotating tube 20.

[0050] Specifically, each support cylinder 31 communicates with the rotating tube 20.

[0051] The sleeve 41 is connected to the rotating tube 20 through a sealing bearing 42, which can ensure that the rotating tube 20 rotates relative to the sleeve 41, and at the same time, the two are still in a communicating state. The pressurized gas transported by the air pump 43 can enter each support cylinder 31 through the lumen of the rotating tube 20, and then drive each sliding structure 44 to fix each bearing in each limiting clamping groove. The air structure is simple, the operation is convenient, and the practicability is strong.

[0052] In some embodiments, the above-mentioned sliding structure 44 can adopt the structure as Figure 1 and Figure 3 shown. Refer to Figure 1 and Figure 3 , each sliding structure 44 includes a sliding column 441 and a push plate 442. Two sliding columns 441 are provided, and the two sliding columns 441 are respectively slidably arranged in the two support cylinders 31, and a piston portion 443 is provided at one end of each sliding column 441 close to the rotating tube 20. The other end extends outwards after passing through the sliding hole provided on the fixing base 32. The push plate 442 is slidably arranged in the embedding groove provided on the bottom surface of the limiting clamping groove and is connected to the extending ends of the two sliding columns 441.

[0053] Specifically, the embedding groove is communicated with each sliding hole.

[0054] The arrangement of the two sliding columns 441 can ensure the support stability of the push plate 442, and thus ensure the smooth ejection of the push plate 442. The piston part 443 on the sliding column 441 can ensure a sealed sliding connection with the lumen of the support cylinder 31, and thus ensure the stability of the push plate 442. The push plate 442 is located in the embedding groove on the bottom surface of the limit groove. After high-pressure gas is filled into the lumen of the rotating tube 20, it can push the sliding columns 441 in the support cylinders 31 to move outwards, so that the push plate 442 pushes each bearing, and the push plate 442 and the two limit strips jointly clamp each bearing, thus effectively avoiding the mutual collision or mutual friction of the bearings and ensuring the quality of the product.

[0055] After the drying work is completed, only need to pump air through the air pump 43 to make the inside of the rotating tube 20 in negative pressure, and then drive each push plate 442 to move reversely into the embedding groove.

[0056] It should be noted that the push plate 442 can be a rectangular plate, and its width is smaller than the inner diameter of the bearing.

[0057] In some embodiments, the above-mentioned push plate 442 can adopt the structure as Figure 2 shown. Refer to Figure 2 . A silicone rubber layer 444 is covered on the outer surface of the push plate 442 to ensure elastic contact with each bearing and avoid damaging each bearing.

[0058] In some embodiments, the above-mentioned driver 50 can adopt the structure as Figure 1 shown. Refer to Figure 1 . The driver 50 is a driving motor, which has low cost, is easy to control, and is convenient for drying work.

[0059] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
