Description

Technical Field

[0001] The utility model belongs to the technical field of bearing cage processing, and particularly relates to a pressing device for a bearing cage. Background Art

[0002] The patent application number 202222039686.8 discloses a pressing device for a bearing cage, including a bottom plate, a support frame, an electric push rod, a pressing sleeve, etc. After the pressing sleeve is controlled to move downward by the lifting mechanism to complete the pressing of the cage, the lifting mechanism moves upward, so that the limiting rod is inserted into the through hole to limit the cage workpiece to be processed, avoiding the unprocessed cage workpiece from sliding out directly without pressing. At the same time, the processed cage directly slides downward through the opening and falls into the collection box to complete automatic blanking. By moving up and down in the above manner, continuous pressing work can be realized, without the need for manual extraction by workers, and at the same time, the problem of the lifting mechanism falling out of control and hurting workers is avoided.

[0003] Although the above disclosed pressing scheme can realize continuous pressing work on the bearing cage, it can only be used for pressing cage workpieces of one diameter and cannot be applied to cage workpieces of different diameters. If the size of the inner wall of the placement plate and the inner cavity of the pressing cylinder is larger than the diameter of the cage workpiece, the position of the cage workpiece will be unstable after sliding, so that it is inconvenient for the pressing sleeve to correspond to the cage workpiece. On the contrary, if the diameter of the cage workpiece is larger, it cannot be placed directly, so processing cannot be carried out. Therefore, a new pressing device is needed, which aims to not only embody the advantages of the original scheme but also be applicable to processing cage workpieces of different diameters. Summary of the Utility Model

[0004] To solve the problems existing in the prior art, the utility model provides a pressing device for a bearing cage, which can not only realize continuous pressing processing but also be applicable to processing cage workpieces of different diameters, and has a wider application range compared with the existing pressing scheme.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A pressing device for a bearing cage, comprising a bottom plate and a cage workpiece. A plurality of supporting plates are provided on the bottom plate, and the cage workpiece is placed on the top of the supporting plates. There are gaps between the plurality of supporting plates. The supporting plates and the bottom plate are fixedly connected by support rods. Both the left and right sides of the top of the bottom plate are fixedly connected with supporting plates. A driving roller is rotatably connected to each of the two supporting plates, and the two driving rollers are connected by a transmission belt. The number of the transmission belts is multiple and they are distributed on both sides of each supporting plate. A plurality of push rods are equidistantly arranged on the outer surface of the transmission belt. A number of threaded grooves are formed on the outer surface of the transmission belt. A spiral thread adapted to the threaded groove is provided on the circumferential surface of the end of the push rod. The distance between the plurality of push rods is adapted to the size of the cage workpiece. A bracket is fixedly connected to the top of the bottom plate, and the bracket is in an L shape. A cylinder is fixedly connected to the inner wall of the top of the bracket. A connecting plate is fixedly connected to the telescopic end of the cylinder.

Embodiment

[0018] See the attached Figures 1-3 As shown, a pressing device for a bearing cage includes a bottom plate 1 and a cage workpiece 2. A plurality of supporting plates 3 are provided on the bottom plate 1. The cage workpiece 2 is placed on the top of the supporting plates 3. There is a gap between the plurality of supporting plates 3. The supporting plates 3 and the bottom plate 1 are fixedly connected by support rods 4. Both the left and right sides of the top of the bottom plate 1 are fixedly connected with support boards 5. Drive rollers 6 are rotatably connected to both support boards 5. The two drive rollers 6 are drivingly connected by a drive belt 7. The number of drive belts 7 is multiple and they are distributed on both sides of each supporting plate 3. A plurality of push rods 8 are equidistantly arranged on the outer surface of the drive belt 7. A plurality of thread grooves 13 are formed on the outer surface of the drive belt 7. A spiral thread adapted to the thread groove 13 is provided on the circumferential surface of the end of the push rod 8. The distance between the plurality of push rods 8 is adapted to the size of the cage workpiece 2. A bracket 9 is fixedly connected to the top of the bottom plate 1. The shape of the bracket 9 is L-shaped. An inner wall of the top of the bracket 9 is fixedly connected with a cylinder 10. A telescopic end of the cylinder 10 is fixedly connected with a connecting plate 11. A plurality of pressing sleeves 12 are fixedly connected to the bottom of the connecting plate 11 by bolts. The plurality of pressing sleeves 12 are respectively located above each supporting plate 3. The left end of the supporting plate 3 is inclined downward. A motor 14 is fixedly connected to the side of one support board 5. An output shaft of the motor 14 is fixedly connected to the drive roller 6 on this support board 5.

[0019] Working principle: In the present utility model, during continuous pressing processing, there are two rows of push rods 8 on both sides of each supporting plate 3. After the cage workpiece 2 is placed on the supporting plate 3, at the circumferential surface outside the cage workpiece 2, four push rods 8 will be in contact with it, thereby limiting the cage workpiece 2 and keeping the position of the cage workpiece 2 stable. Start the motor 14 to drive one driving roller 6 to rotate. With the cooperation of the two driving rollers 6, all the transmission belts 7 move synchronously. All the push rods 8 move leftward synchronously with the transmission belts 7. The limited cage workpiece 2 moves along with the push rods 8. When it moves below the pressing sleeve 12, the motor 14 stops driving. The air cylinder 10 pushes the connecting plate 11 downward, and the connecting plate 11 drives all the pressing sleeves 12 downward to press the cage workpiece 2. Then the air cylinder 10 drives the connecting plate 11 to reset upward. The motor 14 starts again to move the next cage workpiece 2 here and press it again. The speed at which the motor 14 drives the cage workpiece 2 to move here and the time interval of the pressing by the air cylinder 10 can be pre-matched through debugging. In this way, the completed cage workpiece 2 slides downward along the inclined plane when it moves to the left part of the supporting plate 3 with the push rods 8. The push rods 8 turn downward along with the transmission belts 7 and gradually separate from the cage workpiece 2. When completely separated from the cage workpiece 2, the cage workpiece 2 slides off from the left end of the supporting plate 3 by itself. A frame for collecting materials is placed in advance below the left end. The cage workpiece 2 falls into the frame for collection, realizing the continuous pressing work of the cage workpiece 2. When it is necessary to press cage workpieces 2 with different diameters, the connecting bolts connecting the connecting plate 11 and the pressing sleeve 12 are disassembled, the original pressing sleeve 12 is removed, and a pressing sleeve 12 adapted to the cage workpiece 2 is replaced. The standard is that the diameter of the pressing sleeve 12 is the same as that of the cage workpiece 2. Then the push rod 8 is screwed off and screwed into the appropriate thread groove 13 according to the diameter of the cage workpiece 2. The standard is that after the cage workpiece 2 is placed, the adjusted push rod 8 can still be in contact with and limit the cage workpiece 2. In this way, the above steps of the pressing process can be repeated to realize the pressing of cage workpieces 2 with different diameters.

[0020] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model.
