[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The bearing inner ring conveyor belt 2 (model SZSFGY), rubber T-shaped mounting head 10 (model 13325) and spring 13 (model JX110) mentioned in this utility model can be obtained from the market or through private customization.

[0025] Please see Figures 1 to 4 An embodiment of this utility model is provided: an inner and outer ring conveying device for bearing processing, including a bearing processing equipment 1, an inner ring conveyor belt 2 connected to the upper side of the rear end face of the bearing processing equipment 1, an outer ring conveyor belt 3 connected to the lower side of the rear end face of the bearing processing equipment 1, and a first bearing moving guide plate 6 fixed on both sides of the upper end face of the inner ring conveyor belt 2 and the outer ring conveyor belt 3.

[0026] A bearing inner ring conveyor belt 2 and a bearing outer ring conveyor belt 3 are connected to one side of their rear end face by a bearing inner and outer ring conveyor rail 5. A second bearing moving guide plate 7 is fixed on both sides of the upper end face of the bearing inner and outer ring conveyor rail 5. An anti-collision conveyor belt 8 is installed inside the four second bearing moving guide plates 7 and the four first bearing moving guide plates 6. The outer surface of the anti-collision conveyor belt 8 is provided with multiple T-shaped grooves 9. A rubber T-shaped mounting head 10 is slidably inserted inside the T-shaped groove 9. A strip plate 11 is fixed on one side of the outer surface of the rubber T-shaped mounting head 10. A spring groove 12 is provided inside the strip plate 11. A circular plate 14 is contained inside the spring groove 12. A spring 13 is connected between the circular plate 14 and the spring groove 12.

[0027] A connecting rod 15 is connected to the axis of the circular plate 14. An arc-shaped plate 16 is fixed to one side of the outer surface of the connecting rod 15, and an arc-shaped protective cotton 17 is provided on the outer surface of the arc-shaped plate 16. A feeding tray 4 is provided behind both the bearing inner ring conveyor belt 2 and the bearing outer ring conveyor belt 3. The two feeding trays 4 are respectively connected to the two bearing inner and outer ring conveyor rails 5. The feeding tray 4 located behind the bearing inner ring conveyor belt 2 contains the bearing inner ring, and the feeding tray 4 located behind the bearing outer ring conveyor belt 3 contains the bearing outer ring. When the equipment needs to be used, the feeding tray 4 located behind the bearing inner ring conveyor belt 3 is used to feed the bearing outer ring. The inner ring of the bearing is added inside the feeding tray 4 behind the bearing 2, and the outer ring of the bearing is added inside the feeding tray 4 behind the outer ring of the bearing 3. Then, the inner ring of the bearing and the outer ring of the bearing are transferred to the two inner and outer ring conveyor rails 5 respectively through the two feeding trays 4. Then, as the inner ring of the bearing and the outer ring of the bearing move, they will pass through the two inner and outer ring conveyor rails 5 and move to the inner ring conveyor belt 2 and the outer ring conveyor belt 3 respectively, and enter the interior of the bearing processing equipment 1 through the inner ring conveyor belt 2 and the outer ring conveyor belt 3.

[0028] The above technical solution can avoid material mixing when the bearing inner ring and bearing outer ring are transported simultaneously through the equipment, thereby ensuring the smooth progress of subsequent processing steps and improving the processing accuracy of the equipment.

[0029] The arc-shaped protective cotton 17 is arc-shaped in general, and the arc-shaped protective cotton 17 located on the outer surface of the same bearing inner ring conveyor belt 2, bearing outer ring conveyor belt 3, or bearing inner and outer ring conveyor rail 5 corresponds to the position of the two anti-collision conveyor belts 8. When the two feeding trays 4 are started, all anti-collision conveyor belts 8 are started simultaneously. When the anti-collision conveyor belt 8 starts running, the multiple arc-shaped protective cotton 17 located on its outer surface will move together. When a bearing inner ring or a bearing inner ring is about to move to the outer surface of the bearing inner and outer ring conveyor rail 5, bearing inner ring conveyor belt 2, and bearing outer ring conveyor belt 3, it will be clamped by the two arc-shaped protective cotton 17 that are correspondingly positioned and move synchronously, thereby fixing it.

[0030] The two arc-shaped protective cotton 17 that clamp the inner ring of the bearing or the outer ring of the bearing in the above technical solution can prevent the inner ring of the bearing or the outer ring of the bearing from being damaged by collision during transportation, thereby improving the protection strength of the inner and outer rings of the bearing.

[0031] The arc plate 16, which is fixed to the arc-shaped protective cotton 17 on the outer surface, is connected to the spring 13 through the connecting rod 15 and the circular plate 14. Due to the elasticity of the spring 13, when the two arc-shaped protective cotton 17 are respectively clamped on both sides of the bearing inner ring or the outer surface of the bearing inner ring, they will move according to the size of the bearing inner ring and squeeze the spring 13.

[0032] The spring 13 in the above technical solution enables the arc-shaped protective cotton 17 to clamp and fix bearing inner rings of various sizes, thereby improving the flexibility of the equipment.

[0033] An anti-rotation rod is fixedly provided on both sides of the surface of the arc plate 16 facing the nearest strip plate 11, and the anti-rotation rod is movably inserted into the interior of the strip plate 11. By fixing the anti-rotation rod to the outer surface of the arc plate 16 and movably inserting it into the interior of the strip plate 11, the rotation of the arc plate 16 during long-term use can be prevented, thereby improving the stability of the structure.

[0034] The rubber T-shaped mounting head 10 is made of high-elasticity rubber in one piece. The outer surface of the rubber T-shaped mounting head 10 fits against the inner wall of the T-shaped groove 9, and the rubber T-shaped mounting head 10 and the T-shaped groove 9 are slidably connected. By using high-elasticity rubber to make the rubber T-shaped mounting head 10 in one piece, when the rubber T-shaped mounting head 10 moves to the front or rear end of the anti-collision conveyor belt 8, the rubber T-shaped mounting head 10 will undergo appropriate deformation to prevent pulling damage to the anti-collision conveyor belt 8.

[0035] A first protective strip is provided on one side of the anti-collision conveyor belt 8 located inside the first bearing moving guide plate 6, and the first bearing moving guide plate 6 and the first protective strip are fixed together by screws; a second protective strip is provided on one side of the anti-collision conveyor belt 8 located inside the second bearing moving guide plate 7, and the second bearing moving guide plate 7 and the second protective strip are fixed together by screws; the first protective strip and the second protective strip can respectively protect the anti-collision conveyor belt 8 located inside the first bearing moving guide plate 6 and the second bearing moving guide plate 7.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
