Description

Technical Field

[0001] This utility model relates to a conveying mechanism for processing bearing parts, belonging to the field of workpiece conveying technology. Background Technology

[0002] In bearing component manufacturing, many parts are made by cutting or laser processing metal sheets into smaller sizes before further shaping or precision machining, such as bearing cages, bearing dust covers, and bearing retaining rings.

[0003] Currently, when cutting or laser processing metal sheets, the sheets are typically driven by a servo motor mounted at the feed inlet, and simultaneously transported by a lifting mechanism below. Because the contact area between the drive wheel and the metal sheet is fixed, slippage can easily occur when processing smooth metal sheets. This prevents the sheet from maintaining a uniform feed speed, thus affecting processing accuracy and quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying mechanism for processing bearing parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying mechanism for processing bearing parts, comprising a drive wheel installed at the feed inlet of a processing equipment for moving a metal sheet, a carrier plate on one side of the drive wheel, a servo motor mounted on the side of the carrier plate opposite to the drive wheel, the output end of the servo motor being fixedly connected to the drive wheel, the drive wheel being a hollow structure, the side of the drive wheel opposite to the carrier plate being open and fitted with a detachable end cap, and a ring-shaped inflatable airbag concentrically arranged on the annular side of the drive wheel. Multiple vent holes communicating with the inflatable airbag are equidistantly arranged. A straight cylinder is installed at the center of the side of the end cap away from the drive wheel. A connecting rod arranged along the length of the straight cylinder is rotatably installed inside the straight cylinder. A dynamic seal sleeved on the connecting rod is installed on the side of the straight cylinder away from the end cap. A connector for limiting the position of the end of the connecting rod is installed at the end of the connecting rod outside the straight cylinder. A hanging rod is installed at the end of the connecting rod inside the drive wheel. The hanging rod is arranged vertically and a first magnet is installed at the lower end of the hanging rod. Multiple second magnets are installed in a ring equidistantly, aligned with the vent holes and attracted to the first magnet.

[0006] Specifically, the connector includes a connector head, the end of the connecting rod away from the lifting rod is equipped with the connector head, the outer surface of the connector head is fixedly connected with a vertically arranged support rod, the upper end of the support rod is fixedly connected with a connecting plate, and the upper surface of the connecting plate has two symmetrical fixing holes for inserting screws.

[0007] Specifically, a threaded rod is fixedly connected to the side of the connector facing the connecting rod. The threaded rod and the connector are integrally formed. A threaded blind hole is opened on the side of the connecting rod facing the connector, and the connector is threadedly connected to the threaded blind hole.

[0008] Specifically, a perforated disc is fixedly connected to the output end of the servo motor, and a frustum is fixedly connected to the center of the side of the drive wheel facing the carrier plate. The frustum and the drive wheel are integrally formed, and the disc is fixedly connected to the frustum by multiple screws.

[0009] Specifically, an air cylinder is installed on the side of the end cap away from the drive wheel. The air cylinder is arranged parallel to the straight cylinder. A branch pipe is installed on the side of the air cylinder near the end cap. The branch pipe extends through the end cap and into the drive wheel. A piston is slidably installed inside the air cylinder. A threaded post for driving the piston to move is installed at the middle position of the side of the piston away from the branch pipe. One end of the threaded post extends to the outside of the air cylinder and the threaded post is threadedly connected to the air cylinder.

[0010] Specifically, a ring is fitted on the outer surface of the end of the air cylinder near the end cap and is fixedly connected to the air cylinder. The ring is fixedly connected to the end cap by screws. A support rod is fixedly connected to the outer surface of the end of the air cylinder away from the end cap. The lower end of the support rod is in contact with the upper part of the outer surface of the straight cylinder.

[0011] Specifically, a threaded sleeve is fixedly connected to the middle of the side of the air cylinder away from the branch pipe, and the threaded column is threadedly connected to the threaded sleeve. A pin hole for inserting an extension rod is opened on the outer surface of the end of the threaded column outside the air cylinder. An anti-loosening nut is provided between the pin hole and the threaded sleeve, and the anti-loosening nut is threadedly connected to the threaded column.

[0012] Specifically, a limiting ring is provided on the side of the end cover facing the drive wheel. The limiting ring is fixed inside the drive wheel.

[0015] The beneficial effects of this utility model are:

[0016] 1. Rotate the threaded column, which drives the piston to move inside the air cylinder. At this time, the air inside the air cylinder enters the space formed by the end cap and the drive wheel through the branch pipe. As the amount of air in the drive wheel increases, the expansion degree of the air bladder increases. Similarly, when the air in the drive wheel enters the air cylinder, the expansion degree of the air bladder decreases. This allows for adjustment of the distance between the air bladder and the lifting structure on the underside of the drive wheel used to support the metal sheet as needed, meeting the needs of metal sheets of different thicknesses and expanding the scope of application.

[0017] 2. Install the support rod in a suitable position inside the processing equipment using screws, thereby fixing the position of one end of the connecting rod. That is, the position of the first magnet inside the drive wheel remains unchanged. When the servo motor drives the drive wheel to rotate, the drive wheel drives the inflatable airbag to rotate. At this time, the second magnet inside the inflatable airbag rotates together. When the second magnet moves directly below the first magnet, the first magnet and the second magnet attract each other. Under the action of magnetic attraction, the lowest part of the inflatable airbag becomes flat, thereby increasing the contact area between the inflatable airbag and the metal plate and preventing slippage between the inflatable airbag and the metal plate.

[0018] 3. Adjust the length of the threaded rod within the threaded blind hole on the connecting rod, thereby changing the distance between the connector and the connecting rod, i.e., changing the position of the support rod. Without adjusting the position of the drive wheel, the mounting area corresponding to the fixing hole on the connecting plate can be easily adjusted, allowing the connecting plate to be installed in a suitable position on the processing equipment.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figure 1 This utility model provides a technical solution: a conveying mechanism for processing bearing accessories, including a drive wheel 1 installed at the feed inlet of the processing equipment for driving the movement of metal plates. A carrier plate 2 is provided on one side of the drive wheel 1. A base plate 4 is fixedly connected to the lower edge of the side of the carrier plate 2 facing away from the drive wheel 1. Two mounting holes 5 for inserting bolts are symmetrically opened on the upper surface of the base plate 4. The base plate 4 is installed at a suitable position on the processing equipment using the mounting holes 5 to complete the fixation of the position of the carrier plate 2.

[0029] See Figure 1 A servo motor 3 is mounted on the side of the carrier plate 2 facing away from the drive wheel 1. A perforated disc 6 is fixedly connected to the output end of the servo motor 3. A frustum 7 is fixedly connected to the center of the side of the drive wheel 1 facing the carrier plate 2. The frustum 7 and the drive wheel 1 are integrally formed. The disc 6 is fixedly connected to the frustum 7 by multiple screws. The carrier plate 2 provides a mounting carrier for the servo motor 3. The disc 6 and the frustum 7 are connected by screws, which facilitates the disassembly and assembly of the servo motor 3 and the drive wheel 1. The frustum 7 is mounted on the drive wheel 1 to locally increase the wall thickness of the connection between the drive wheel 1 and the disc 6.

[0030] See Figure 4 The drive wheel 1 has a hollow structure. The side of the drive wheel 1 facing away from the carrier plate 2 is open and has a detachable end cover 26. The end cover 26 has a limiting ring 31 on the side facing the drive wheel 1. The limiting ring 31 is fixed inside the drive wheel 1. The end cover 26 is fixedly connected to the limiting ring 31 by multiple screws. A sealing ring is provided between the end cover 26 and the limiting ring 31. The sealing ring is installed between the limiting ring 31 and the end cover 26 to improve the sealing performance between the end cover 26 and the limiting ring 31.

[0031] See Figure 1 , Figure 3 and Figure 4 The drive wheel 1 has a ring-shaped inflatable airbag 8 arranged concentrically on its annular side. Multiple vent holes 25, communicating with the inflatable airbag 8, are equidistantly spaced on the annular side of the drive wheel 1. An air cylinder 14 is mounted on the side of the end cap 26 facing away from the drive wheel 1. The air cylinder 14 is arranged parallel to the straight cylinder 9. A branch pipe 32 is mounted on the side of the air cylinder 14 near the end cap 26, extending through the end cap 26 into the drive wheel 1. A ring 30, fixedly connected to the air cylinder 14, is fitted onto the outer surface of the end of the air cylinder 14 near the end cap 26. The ring 30 is screwed to the end cap 26. 6. Fixed connection: The ring 30 facilitates the assembly and disassembly of the air cylinder 14 and the end cap 26. A support rod 20 is fixedly connected to the outer surface of the end of the air cylinder 14 away from the end cap 26. The lower end of the support rod 20 contacts the upper part of the outer surface of the straight cylinder 9, providing auxiliary support for the air cylinder 14. A piston 29 is slidably installed inside the air cylinder 14. A threaded post 19 for driving the piston 29 is installed at the middle of the side of the piston 29 away from the branch pipe 32. One end of the threaded post 19 extends to the outside of the air cylinder 14 and is threadedly connected to the air cylinder 14. The side of the air cylinder 14 away from the branch pipe 32... A threaded sleeve 28 is fixedly connected at the center of the cylinder 14. A threaded post 19 is threaded into the threaded sleeve 28, thus connecting the threaded post 19 to the cylinder 14. A pin hole 17 for inserting an extension rod is provided on the outer surface of the end of the threaded post 19 outside the cylinder 14. The extension rod is inserted into the pin hole 17, facilitating the tightening of the threaded post 19. A lock nut 18 is provided between the pin hole 17 and the threaded sleeve 28, threaded onto the threaded post 19. Tightening the lock nut 18 ensures a tight fit between the lock nut 18 and the threaded sleeve 28, preventing the threaded post 19 from moving away. The piston 29 moves within the air cylinder 14 when the threaded column 19 is rotated. At this time, the air in the air cylinder 14 enters the space formed by the end cap 26 and the drive wheel 1 through the branch pipe 32. As the amount of air in the drive wheel 1 increases, the expansion degree of the inflatable airbag 8 increases. Similarly, when the air in the drive wheel 1 enters the air cylinder 14, the expansion degree of the inflatable airbag 8 decreases. This allows for adjustment of the distance between the inflatable airbag 8 and the lifting structure on the lower side of the drive wheel 1 used to support the metal sheet as needed, meeting the needs of metal sheets of different thicknesses and expanding the scope of application.

[0032] See Figure 1 , Figure 2 , Figure 4 and Figure 6A straight cylinder 9 is installed at the center of the side of the end cap 26 facing away from the drive wheel 1. A connecting rod 10, arranged along the length of the straight cylinder 9, is rotatably installed inside the straight cylinder 9. A dynamic seal 27, sleeved on the connecting rod 10, is installed on the side of the straight cylinder 9 away from the end cap 26. The dynamic seal 27 seals the connection between the connecting rod 10 and the straight cylinder 9 and also connects the straight cylinder 9 and the connecting rod 10. A connector 11 is installed at the end of the connecting rod 10 away from the lifting rod 21. A vertically arranged support rod 12 is fixedly connected to the outer surface of the connector 11. A connecting plate 13 is fixedly connected to the upper end of the support rod 12. Two fixing holes for inserting screws are symmetrically opened on the upper surface of the connecting plate 13. 16. A threaded rod 15 is fixedly connected to the side of the connector 11 facing the connecting rod 10. The threaded rod 15 and the connector 11 are integrally formed. A threaded blind hole 33 is opened on the side of the connecting rod 10 facing the connector 11. The connector 11 is threadedly connected in the threaded blind hole 33. By adjusting the length of the threaded rod 15 in the threaded blind hole 33 on the connecting rod 10, the distance between the connector 11 and the connecting rod 10 is changed, that is, the position of the support rod 12 is changed. Without adjusting the position of the drive wheel 1, the installation area corresponding to the fixing hole 16 on the connecting plate 13 can be conveniently adjusted, so that the connecting plate 13 can be installed in a suitable position on the processing equipment.

[0033] See Figure 1 , Figure 4 and Figure 5 A suspension rod 21 is installed at one end of the connecting rod 10 inside the drive wheel 1. The suspension rod 21 is arranged vertically and a first magnet 23 is installed at the lower end of the suspension rod 21. A carrier plate 22 is fixedly connected to the end of the suspension rod 21 away from the connecting rod 10. The first magnet 23 is fixed on the side of the carrier plate 22 away from the suspension rod 21. The carrier plate 22 serves to connect the first magnet 23 and the suspension rod 21. The suspension rod 21 and the connecting rod 10 are arranged perpendicular to each other. Multiple second magnets 24 are installed in a ring at equal intervals inside the inflatable airbag 8, aligned with the vent 25 and attracted to the first magnet 23. The support rod 12 is installed inside the processing equipment using screws. At a suitable position, the position of one end of the connecting rod 10 is fixed, that is, the position of the first magnet 23 inside the drive wheel 1 remains unchanged. When the servo motor 3 drives the drive wheel 1 to rotate, the drive wheel 1 drives the inflatable airbag 8 to rotate. At this time, the second magnet 24 inside the inflatable airbag 8 rotates together. When the second magnet 24 moves directly below the first magnet 23, the first magnet 23 and the second magnet 24 attract each other. Under the action of magnetic attraction, the lowest part of the inflatable airbag 8 becomes flat, thereby increasing the contact area between the inflatable airbag 8 and the metal plate and preventing slippage between the inflatable airbag 8 and the metal plate.

[0034] Detailed Implementation: The base plate 4 is installed at a suitable position on the processing equipment using the mounting hole 5, thus fixing the position of the carrier plate 2. This restricts the position of the servo motor 3. The length of the threaded rod 15 within the threaded blind hole 33 on the connecting rod 10 is adjusted, thereby changing the distance between the connector 11 and the connecting rod 10, which in turn changes the position of the support rod 12. Without adjusting the position of the drive wheel 1, the installation area corresponding to the fixing hole 16 on the connecting plate 13 can be easily adjusted, allowing the connecting plate 13 to be installed at a suitable position on the processing equipment. The threaded column 19 is rotated, causing the piston 29 to move within the air cylinder 14. At this time, the air in the air cylinder 14 enters the space formed by the end cap 26 and the drive wheel 1 through the branch pipe 32. As the amount of air in the drive wheel 1 increases, the expansion degree of the inflatable airbag 8 increases. Similarly, when the air in the drive wheel 1 enters the air cylinder 14, the expansion degree of the inflatable airbag 8 decreases. This allows for adjustment of the distance between the inflatable airbag 8 and the support structure on the lower side of the drive wheel 1 used to support the metal sheet as needed, meeting the needs of metal sheets of different thicknesses and expanding the scope of application.

[0035] When the servo motor 3 drives the drive wheel 1 to rotate, the drive wheel 1 drives the inflatable airbag 8 to rotate. At this time, the second magnet 24 inside the inflatable airbag 8 rotates together. When the second magnet 24 moves directly below the first magnet 23, the first magnet 23 and the second magnet 24 attract each other. Under the action of magnetic attraction, the lowest part of the inflatable airbag 8 becomes flat, thereby increasing the contact area between the inflatable airbag 8 and the metal plate, preventing slippage between the inflatable airbag 8 and the metal plate.
