[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figure 1 - Figure 3 For one embodiment provided by the present utility model: A feeding device for a grinding machine for machining the inner spherical surface of a bearing includes a base 1, which serves as the basic structure of the entire feeding device, provides a platform for supporting and installing components, and at the same time has a control panel provided on its front side for controlling the first drive motor 3 and the second drive motor 6. A slideway is provided at the top of the base 1 for installing the conveyor belt 2 and providing protection for the bearing ring during movement. The conveyor belt 2 is provided on the inner wall of the slideway and is responsible for transporting the bearing ring to be machined from one position to another position to achieve continuous feeding. This technology is an existing technology, so it will not be elaborated here. A first drive motor 3 is provided on the upper inner wall of the base 1 to provide power for the worm 45 in the adjustment assembly. Through the meshing transmission of the worm 45 and the worm gear 44, the bi-directional threaded rod 43 is driven to rotate. An adjustment assembly is provided on the upper part of the base 1. The adjustment assembly includes a guide plate 41. Under the action of the bi-directional threaded rod 43, the guide plate 41 can move left and right, thereby adjusting the distance between the two guide plates 41 to adapt to bearing rings of different sizes, improving the applicability and stability of the device.
[0033] Furthermore, the guiding plate 41 is slidably connected to the upper inner wall of the base 1. A connecting column is fixedly connected to the front side of the guiding plate 41, and the connecting column is slidably connected to the upper inner wall of the base 1. There are multiple groups of connecting columns, which are used to connect the guiding plate 41 and the moving plate 42. By setting multiple groups, the stability of the guiding plate 41 can be increased. A moving plate 42 is fixedly connected to the front side of the connecting column. By moving the moving plate 42, the connecting column is driven to move, thereby driving the guiding plate 41 to move. The lower part of the moving plate 42 is slidably connected to the inner wall of the base 1. A bidirectional threaded rod 43 is threadedly connected through the inner wall of the moving plate 42. By rotating forward and backward, the two moving plates 42 can be made to approach or move away from each other, thereby adjusting the position of the guiding plate 41 to adapt to bearing rings of different sizes. The bidirectional threaded rod 43 is rotatably connected to the inner wall of the base 1.
[0034] Refer to Figure 2 and Figure 3 , a worm gear 44 is fixedly connected to the outer side of the middle part of the bidirectional threaded rod 43 and meshes with a worm 45, converting the rotational movement of the worm 45 into the rotational movement of the bidirectional threaded rod 43. The bottom end of the worm gear 44 meshes with the worm 45 and rotates driven by the first driving motor 3. Through the meshing transmission with the worm gear 44, the bidirectional threaded rod 43 is driven to rotate. The left side of the worm 45 is fixedly connected to the right side of the output shaft of the first driving motor 3. The self-locking ability of the first driving motor 3, the worm gear 44 and the worm 45 is used to prevent the moving plate 42 from moving, thereby ensuring the stability of the device.
[0035] Furthermore, there are two groups of guiding plates 41 and moving plates 42. A sponge pad is provided on the opposite side of the two groups of guiding plates 41, which can play a role in protecting the bearing ring and prevent the bearing from being scratched during transportation. The inner wall of the slideway is made of rubber material, which can achieve the functions of shock absorption and anti-slip, reduce the vibration and sliding of the bearing ring during transportation, and ensure the stability of transportation.
[0036] Refer to Figure 4 and Figure 5 , a limiting component is provided on the right side of the base 1. The limiting component includes a limiting rod 51. When one group of limiting rods 51 on the right side descends, the other group of limiting rods 51 ascends, enabling a group of bearing rings to enter the processing area of the grinding machine. When one group of limiting rods 51 on the left side descends, the other group of limiting rods 51 ascends to limit the bearing rings entering between the two groups of limiting rods 51, thereby controlling the blanking speed. The limiting rods 51 are slidably connected to the inner wall of the base 1 and there are two groups. The bottom ends of the two groups of limiting rods 51 are rotatably connected to sliders 52. The opposite outer sides of the two groups of sliders 52 are slidably connected to a fixed block 53. By rotating the fixed block 53, the two groups of sliders 52 are driven to swing reciprocally, thereby driving the two groups of limiting rods 51 to move up and down respectively to limit the bearing rings. Then, through the inclined surface provided on the right side of the base 1, the bearing rings roll by gravity.
[0037] Further, the fixing block 53 is rotatably connected to the inner wall of the base 1. A telescopic rod 54 is fixedly connected to the rear side of the fixing block 53. By rotating the turntable 55, the telescopic rod 54 is driven to swing reciprocally, thereby driving the two limiting rods 51 to move up and down respectively. The front part of the left side of the telescopic rod 54 is rotatably connected to the turntable 55, which rotates under the drive of the second driving motor 6. Through the connection with the telescopic rod 54, the fixing block 53 is driven to swing. The second driving motor 6 is fixedly connected to the front side of the base 1 near the turntable 55. The output shaft of the second driving motor 6 is fixedly connected to the front side of the turntable 55, providing power for the turntable 55 and thus driving the telescopic rod 54 to move.
[0038] Working principle: When in use, first start the first driving motor 3 to drive the worm 45 to rotate. The worm 45 meshes with the worm gear 44 for transmission, causing the bidirectional threaded rod 43 to rotate. The rotation of the bidirectional threaded rod 43 makes the two moving plates 42 threadedly connected thereto approach or move away from each other. The moving plates 42 drive the guide plate 41 to move through the connecting columns, adjusting the distance between the two guide plates 41 to adapt to the size of the bearing ring to be processed. Place the bearing ring to be processed on the conveyor belt 2 in the top slideway of the base 1, and convey the bearing ring from one position to another position to achieve continuous feeding.
[0039] At the same time, through the control panel, start the second driving motor 6 to drive the turntable 55 to rotate. The rotation of the turntable 55 drives the telescopic rod 54 to swing reciprocally. The swing of the telescopic rod 54 drives the fixing block 53 to rotate on the inner wall of the base 1. The rotation of the fixing block 53 makes the two sliding blocks 52 slidably connected thereto swing and move reciprocally. The movement of the sliding blocks 52 drives the two limiting rods 51 rotatably connected thereto to move up and down respectively. When the right limiting rod 51 descends, the other limiting rod 51 ascends, enabling a bearing ring to enter the processing area of the grinding machine to process the inner spherical surface of the bearing. When the left limiting rod 51 descends, the other limiting rod 51 ascends to limit the bearing ring entering between the two limiting rods 51, thereby controlling the blanking speed.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
