Description

Technical Field

[0001] This invention relates to the field of bearing assembly technology, specifically an automatic bearing assembly device. Background Technology

[0002] Bearings are crucial components in the mechanical field. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy, enabling various rotating components to operate smoothly and efficiently. Common types of bearings include rolling bearings and sliding bearings. The quality of bearing installation directly affects the bearing's accuracy, lifespan, and performance.

[0003] Chinese patent CN109940545B discloses a bearing installer, comprising an insulating housing, an electromagnet, a bearing clamping component, and a hammer. The insulating housing has an internal slide chamber, with a first conductive plate and a second conductive plate at the closed end of the slide chamber. The hammer is located inside the slide chamber, its outer wall connected to the second conductive plate, and one end has a conductive contact. The electromagnet includes an iron core, a coil, a power supply, and a switch. The iron core and the first conductive plate are located at opposite ends of the hammer, with a connecting spring between the iron core and the hammer. One end of the coil is connected to the first conductive plate, and the other end is connected to the negative terminal of the power supply; the positive terminal of the power supply is connected to the second conductive plate. The bearing clamping component is located at the open end of the insulating housing, with one end movably connected to the iron core and the other end used to mate with the end face of the bearing. This method uses electromagnetic clamping to tighten the bearing, resulting in uniform bearing force, and the installation process eliminates the need for manual hammering, thus protecting the safety of workers.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent involves manually placing the bearing, where the iron core gains magnetism through a coil, attracting a hammer. Under the magnetic attraction, the hammer moves along the slide towards the iron core and strikes it. The iron core and the bearing clamps at its outer end are displaced and pressed against the bearing under the impact. This manual placement of the bearing results in low bearing installation efficiency.

[0006] 2. This patent cannot be used for multi-station installation, and it cannot automatically press the spring in after the bearing is installed, resulting in low processing efficiency.

[0007] Based on this, the present invention designs an automatic bearing assembly device to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide an automatic bearing assembly device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0013] Furthermore, the passive pressing assembly includes an extension plate and a baffle. The extension plate is fixedly installed at the center of the fixed frame away from the rotating disk, and the baffle is fixedly installed on the upper side of the extension plate to prevent the bearing from rolling off. The extension plate is provided with a groove to accommodate the bearing.

[0014] Furthermore, the workpiece fixing device includes a first cylinder and a pressure rod, wherein the first cylinder is fixedly mounted on the upper side of the cam, and the pressure rod is fixedly mounted on the output end of the first cylinder.

[0015] Furthermore, the bearing conveying mechanism includes: a support plate, a stop block, a feed plate, a second cylinder, a first linear module, and a second linear module. The support plate is fixedly installed on the upper side of the frame, and a circular slot is provided on the support plate for placing the bearing. The stop block is fixedly installed in the circular slot for limiting the bearing, facilitating the subsequent clamping of multiple bearings at once. The feed plate is fixedly installed on the left side of the support plate, and a slot is provided in the middle of the feed plate for the bearing to roll within the slot. A first through-hole is provided on the lower side of the feed plate for accommodating the output end of the second cylinder. The first circular hole is connected to the circular slot. The second cylinder is fixedly installed on the left side of the frame via a bracket, and the output end of the second cylinder is located in the first circular hole. The first linear module is fixedly installed on the upper side of the frame, and the second linear module is fixedly installed at the output end of the first linear module. A gripper is fixedly installed at the output end of the second linear module for clamping the bearing.

[0016] Furthermore, the spring assembly mechanism includes: a linear guide shaft, a linear bearing, an extension plate, a third cylinder, and a spring pressing assembly. Multiple linear guide shafts are fixedly mounted on the right side of the frame. A linear bearing is slidably connected to each linear guide shaft. The extension plate is fixedly mounted on the linear bearing. Two through-holes are provided on the extension plate to accommodate the spring. The third cylinder is fixedly mounted on the upper side of the linear guide shaft via a bracket. The output end of the third cylinder is fixedly connected to the extension plate. The spring pressing assembly is mounted on the left side of the extension plate.

[0017] Furthermore, the spring pressing assembly includes: a fourth cylinder, a fixed bracket, a sliding block, a guide rod, a sliding sleeve, a fifth cylinder, a connecting plate, and a pressing rod. The fourth cylinder is fixedly installed on the left side of the extension plate, the fixed bracket is fixedly installed on the upper side of the extension plate, and the fixed bracket is provided with a spring input port.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention utilizes a bearing feeding mechanism. The bearing is fed into a slot on the middle side of the feeding plate via a pusher plate, and rolls from the slot into a first circular hole on the lower side of the feeding plate. The output end of a second cylinder moves towards the first circular hole, pushing the bearing into a circular slot on a support plate. Multiple bearings accumulate in the circular slot on the support plate. The first and second linear modules drive the gripper to move, clamping multiple bearings onto the extension plate of the passive pressing assembly at once. This facilitates placing multiple bearings on the extension plate at once, improving conveying efficiency. Multiple bearings are then conveyed to the upper side of the passive pressing assembly via a bearing conveying mechanism. The rotation of the hollow rotating platform drives the rotating disk to rotate, which, in conjunction with the cam, causes the elastic sliding assembly to move, pushing the bearing into the workpiece. This facilitates the rapid and continuous pressing of bearings into the workpiece.

[0020] The hollow rotary platform rotates, driving the rotary disk to rotate. The rotary disk then drives the fixed frame to rotate. When the fixed frame rotates to the cam position, the rollers and cam work together to push the sliding plate away from the center of the rotary disk. At this point, the spring is installed and inserted into the workpiece for multi-station processing. The workpiece with the bearing pressed in enters the spring assembly mechanism through the rotation of the rotary disk, where the spring is pressed in, thus improving processing efficiency.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] The present invention will be further described below with reference to embodiments.

[0038] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0039] Example 1

[0040] Please see Figure 1-12 In this embodiment of the invention, an automatic bearing assembly device includes a frame 1, a hollow rotating platform 2 mounted on the middle side of the frame 1, a cam 3 disposed inside the hollow shaft of the hollow rotating platform 2, the cam 3 being fixedly mounted on the frame 1 and not rotating with the hollow rotating platform 2, a workpiece fixing device 9 being fixedly mounted on the upper side of the cam 3, a rotating disk 4 being fixedly mounted on the output end of the hollow rotating platform 2, a plurality of sliding mounting devices 5 being fixedly mounted on the upper side of the rotating disk 4, a bearing conveying mechanism 6 being mounted on the left side of the frame 1, a spring assembly mechanism 7 being mounted on the right side of the frame 1, and a workpiece 8 being disposed on the upper side of the sliding mounting device 5.

[0041] The bearings are fed into the bearing conveying mechanism 6 via the push plate feeder. Multiple bearings are conveyed to the sliding mounting device 5 via the bearing conveying mechanism 6. The rotating disk 4 is driven to rotate by the rotation of the hollow rotating platform 2. In conjunction with the cam 3, the bearings are conveyed into the workpiece 8. The spring assembly mechanism 7 on the right side of the frame 1 installs the spring into the workpiece 8.

[0042] The sliding mounting device 5 includes an elastic sliding component and a passive pressing component. The elastic sliding component is mounted on the upper side of the rotating disk 4, and the passive pressing component is mounted on the upper side of the elastic sliding component. A workpiece 8 is disposed on the upper side of the elastic sliding component.

[0043] Multiple bearings are conveyed to the upper side of the passive pressing component through the bearing conveying mechanism 6. The rotation of the hollow rotating platform 2 drives the rotating disk 4 to rotate, which, in conjunction with the cam 3, causes the elastic sliding component to move, pushing the bearings into the workpiece 8. This facilitates the rapid and continuous pressing of the bearings into the workpiece 8.

[0044] The elastic sliding assembly includes: a fixed frame 51, guide rails 52, sliders 53, sliding plates 54, fixed rods 55, fixed springs 56, and rollers 57. The fixed frame 51 is fixedly mounted on the rotating disk 4. Multiple guide rails 52 are fixedly mounted on the fixed frame 51, and multiple sliders 53 are slidably connected to each guide rail 52. The lower side of the sliding plate 54 is fixedly mounted on the upper side of the sliders 53. Multiple fixed rods 55 are fixedly mounted on the fixed frame 51, and the upper side of the sliding plate 54 is slidably connected to the fixed rods 55. The fixed spring 56 is disposed on the fixed rod 55, with one end of the fixed spring 56 tightly attached to the fixed frame 51 and the other end tightly attached to the sliding plate 54. The rollers 57 are rotatably connected to the sliding plate 54 near the center of the rotating disk 4 via a rotating shaft.

[0045] The rotation of the hollow rotating platform 2 drives the rotating disk 4 to rotate, and the rotation of the disk drives the fixed frame 51 to rotate. The fixed frame 51 rotates to the position of the cam 3. The roller 57 and the cam 3 work together to push the sliding plate 54 away from the center of the rotating disk 4. At this time, the spring is installed and installed into the workpiece 8. The bearing is fixed by the cooperation of the bracket and the spring. The bracket is installed into the workpiece 8 by an external robot.

[0046] The passive pressing assembly includes an extension plate 58 and a baffle 59. The extension plate 58 is fixedly installed on the center of the fixed frame 51 away from the rotating disk 4. The baffle 59 is fixedly installed on the upper side of the extension plate 58 to prevent the bearing from rolling off. The extension plate 58 is provided with a groove to accommodate the bearing.

[0047] Multiple bearings are placed in the groove of the extension plate 58, and the baffle 59 is used to prevent the bearings from rolling off. The bearings are conveyed into the workpiece 8 by the relative movement of the sliding plate 54 and the extension plate 58.

[0048] The workpiece fixing device 9 includes a first cylinder 91 and a pressure rod 92. The first cylinder 91 is fixedly installed on the upper side of the cam 3, and the pressure rod 92 is fixedly installed on the output end of the first cylinder 91.

[0049] The downward movement of the output end of the first cylinder 91 causes the pressure rod 92 to move downward, further fixing the workpiece 8 onto the sliding plate 54, which is beneficial for the subsequent pressing of the spring.

[0050] The bearing conveying mechanism 6 includes: a support plate 61, a stop block 62, a feed plate 63, a second cylinder 64, a first linear module 65, and a second linear module 66. The support plate 61 is fixedly installed on the upper side of the frame 1. A circular slot is provided on the support plate 61 for placing bearings. The stop block 62 is fixedly installed in the circular slot to limit the bearing movement, facilitating the subsequent clamping of multiple bearings at once. The feed plate 63 is fixedly installed on the left side of the support plate 61. A slot is provided in the middle of the feed plate 63 for bearings to be placed in the slot. The feed plate 63 has a through-hole 10 on its lower side to accommodate the output end of the second cylinder 64. The first hole 10 is connected to a circular slot. The second cylinder 64 is fixedly mounted on the left side of the frame 1 by a bracket. The output end of the second cylinder 64 is located in the first hole 10. The first linear module 65 is fixedly mounted on the upper side of the frame 1. The second linear module 66 is fixedly mounted on the output end of the first linear module 65. The output end of the second linear module 66 is fixedly mounted with a gripper for gripping the bearing.

[0051] The bearings are fed by the pusher plate feeder and enter the slot on the middle side of the feed plate 63. They roll from the slot into the first circular hole 10 on the lower side of the feed plate 63. The output end of the second cylinder 64 moves towards the first circular hole 10, pushing the bearings into the circular slot on the support plate 61. Multiple bearings accumulate in the circular slot on the support plate 61. The first linear module 65 and the second linear module 66 drive the gripper to move, clamping multiple bearings onto the extension plate 58 of the passive pressing component at one time. This facilitates placing multiple bearings on the extension plate 58 at one time, improving the conveying efficiency.

[0052] Example 2

[0053] like Figure 1-12 As shown, in a preferred embodiment of the present invention, the spring assembly mechanism 7 includes: a linear guide shaft 71, a linear bearing 72, an extension plate 73, a third cylinder 74, and a spring pressing assembly. Multiple linear guide shafts 71 are fixedly mounted on the right side of the frame 1. A linear bearing 72 is slidably connected to each linear guide shaft 71. The extension plate 73 is fixedly mounted on the linear bearing 72. Two through-holes 11 are provided on the extension plate 73 for accommodating the spring. The third cylinder 74 is fixedly mounted on the upper side of the linear guide shaft 71 via a bracket. The output end of the third cylinder 74 is fixedly connected to the extension plate 73. The spring pressing assembly is mounted on the left side of the extension plate 73.

[0054] The downward movement of the output end of the third cylinder 74 causes the extension plate 73 to move downward. The downward movement of the extension plate 73 causes the spring pressing assembly to move downward, so that the spring pressing assembly is close to the workpiece 8. The second round hole 11 on the extension plate 73 is close to the spring pressing inlet of the workpiece 8, which facilitates the pressing of the spring into the workpiece 8.

[0055] The spring pressing assembly includes: a fourth cylinder 75, a fixed bracket 76, a sliding block 77, a guide rod 78, a sliding sleeve 79, a fifth cylinder 710, a connecting plate 711, and a pressing rod 712. The fourth cylinder 75 is fixedly installed on the left side of the extension plate 73. The fixed bracket 76 is fixedly installed on the upper side of the extension plate 73 and has a spring input port 13. The sliding block 77 is slidably connected to the fixed bracket 76 and has two through-holes 12 for accommodating the spring. The two guide rods 78 are fixedly installed on the left side of the extension plate 73 and each guide rod 78 is slidably connected to a sliding sleeve 79. The fifth cylinder 710 is fixedly installed on the upper side of the guide rod 78 via a bracket. The connecting plate 711 is fixedly installed on the sliding sleeve 79 and the output end of the fifth cylinder 710 is fixedly connected to the connecting plate 711. The two pressing rods 712 are fixedly installed on the lower side of the connecting plate 711 and are disposed within the third holes 12.

[0056] The spring is fed to the spring input port 13 on the fixed bracket 76 by an external feeding mechanism. The spring falls from the spring input port 13 into the third round hole 12 of the sliding block 77. The output end of the fourth cylinder 75 moves towards the center of the rotating disk 4, which drives the sliding block 77 to move towards the center of the rotating disk 4, and moves the spring to the second round hole 11 of the extension plate 73. The second round hole 11 on the extension plate 73 is close to the spring pressing inlet of the workpiece 8. The output end of the fifth cylinder 710 moves downward, which drives the pressing rod 712 on the connecting plate 711 to move downward, pressing the spring in the third round hole 12 into the workpiece 8, which is beneficial for spring feeding and pressing.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
