Abstract
Description
Technical Field
[0001] This application relates to the field of grinding apparatus technology, and more specifically, to a grinding apparatus for steel balls. Background Technology
[0002] Grinding of spheres typically uses specialized grinding or polishing machines, with the appropriate equipment and process selected based on the specific material and precision requirements.
[0003] For example, Chinese Patent Publication No. CN116494043A discloses the following technical solution: a sphere processing machine, comprising: a work plate; clamping devices disposed on both sides of the work plate; a fluid orifice enlarging device disposed on the work plate, with the fluid orifice enlarging device located on both sides of the clamping device; a grinding device disposed on the work plate, with the grinding device located between the clamping devices; and a cooling device disposed on the work plate; wherein, the clamping devices are used to clamp the initial shape of the sphere, the fluid orifice enlarging device is used to enlarge the fluid orifice, and the fluid orifice enlarging device can also clamp the inner wall of the enlarged fluid orifice, and the grinding device is used to grind the outer wall of the initial shape of the sphere.
[0004] The existing technology has the following problems: To achieve spherical grinding, the aforementioned device requires at least three hydraulic cylinders and a complex arc-shaped grinding head to coordinate the head's movement, including its forward and backward movement, lifting, oscillation, and curvature adjustment. Even so, the sphere's rotation relies solely on a fixed axis (the axis of the fluid orifice held by the internal mechanism). This means the sphere can only rotate around one axis. To grind the entire surface, it must rely heavily on the grinding head's complex movements in multiple degrees of freedom to "find" the spherical surface. This results in complex motion control and potential grinding dead zones or unevenness issues. Summary of the Invention

[0018] (3) This application solves the friction problem between the steel ball and the electromagnetic support seat during the rotation process by setting up a lifting control component. Through the sliding cooperation between the slide rod and the guide groove, the lifting of the electromagnetic support seat can be precisely controlled, avoiding wear of the support seat during the rotation of the steel ball, thereby extending the service life of the equipment. In addition, the lifting control component also improves the stability and reliability of the equipment, making the contact between the support seat and the steel ball more precise during the steel ball grinding process, effectively avoiding frictional wear, and facilitating subsequent loading and unloading operations.

[0027] Example 1, please refer to Figures 1-7 This embodiment provides a steel ball grinding device, including: a housing 1; a horizontal plate 2, which is fixedly connected to the inner wall of the housing 1; and a through-hole 3, which is opened on both sides of the housing 1. A rotating shaft 41 is rotatably connected to the middle of the horizontal plate 2. A U-shaped plate 42 is fixedly connected to the upper end of the rotating shaft 41. A rotating rod 43 is rotatably connected to one side of the U-shaped plate 42. A limit cover A44 is fixedly connected to the inner end of the rotating rod 43. A moving rod 45 slides through the other side of the U-shaped plate 42. A limit cover B46 is fixedly connected to the inner end of the moving rod 45. A motor is fixedly connected to the bottom of the inner part of the housing 1. A transmission shaft 49 is fixedly connected to the output end of the motor. A rotating plate 410 is fixedly connected to the upper end of the transmission shaft 49. A sliding shaft 411 is fixedly connected to the upper end of the rotating plate 410. A swing rod 412 is fixedly sleeved on the outer wall. A groove 413 is opened in the middle of the swing rod 412. Control components for controlling the movement rod 45 are assembled on the inner and outer sides of the shaped plate 42. A mounting shaft 414 is rotatably connected to the outer wall of the shaped plate 42. A gear 415 is fixedly sleeved on the outer wall of the mounting shaft 414. An arc-shaped toothed plate 416 is fixedly connected to the outer wall of the housing 1. A transmission wheel A417 is fixedly sleeved on the outer wall of the mounting shaft 414. A transmission wheel B419 is fixedly sleeved on the outer wall of the rotating rod 43. A transmission belt 418 is wound around the outer walls of the transmission wheels A417 and B419.
[0028] The control components include an electric actuator 47, which is fixedly connected to the inner side of the U-shaped plate 42. A connecting plate 48 is fixedly connected to the output end of the electric actuator 47, and the inner side of the connecting plate 48 is fixedly connected to the outer end of the moving rod 45. The end of the sliding shaft 411 away from the rotating plate 410 is slidably connected to the inside of the sliding groove 413. A gear 415 is located at the upper end of the arc-shaped toothed plate 416, and the gear 415 meshes with the arc-shaped toothed plate 416.
[0029] The upper end of the housing 1 is equipped with a grinding component, which includes an electric slide rail 71. The electric slide rail 71 is located at the upper end of the housing 1. A movable plate 72 is slidably connected to the outer wall of the electric slide rail 71. A grinding belt 73 is provided at the upper end of the movable plate 72.
[0030] In use, first place the steel ball on the upper end of the electromagnetic support base 53, so that one side of the steel ball is inside the limiting cover A44. Then, start the electric push rod 47 to move the connecting plate 48. The connecting plate 48 will then move the moving rod 45 towards the middle of the housing 1. The moving rod 45 will then move the limiting cover B46, thus fixing the steel ball. Then, start the electric slide rail 71 to move the moving plate 72 towards the steel ball. When the grinding belt 73 at the upper end of the moving plate 72 contacts the surface of the steel ball, start the grinding belt 73 to grind the steel ball. At the same time, start the motor to... The drive shaft 49 is rotated, which in turn drives the rotating plate 410 to rotate. The sliding shaft 411 at the upper end of the rotating plate 410 will then rotate around the drive shaft 49. Since the sliding shaft 411 is slidably connected in the groove 413 in the middle of the swing rod 412, the rotation of the sliding shaft 411 will drive the swing rod 412 to rotate. The swing rod 412 will then drive the shaped plate 42 to swing left and right through the rotating shaft 41. The mounting shaft 414 on the outer side of the shaped plate 42 will also swing accordingly, and the gear 415 on the outer wall of the mounting shaft 414 will also swing left and right around the rotating shaft 41. Since gear 415 and arc-shaped toothed plate 416 are always meshed, as gear 415 swings with the swivel of the swivel plate 42, it will roll along the trajectory of the arc-shaped toothed plate 416, thereby causing the mounting shaft 414 to rotate. The rotation of the mounting shaft 414 can drive the transmission wheel A417 fixedly sleeved on its outer wall to rotate synchronously. The transmission wheel A417 transmits power to the transmission wheel B419 on the outer wall of the rotating rod 43 through the transmission belt 418, causing the rotating rod 43 to rotate accordingly. The rotation of the rotating rod 43 directly drives the inner end of the limiting cover A44 to rotate. The limiting cover A44 and the limiting cover B46 together fix the steel ball. Therefore, the steel ball will rotate during the grinding process. With the left and right swing of the swivel plate 42, the surface of the steel ball can fully contact the grinding belt 73 to achieve all-round uniform grinding.
[0031] Example 2, please refer to Figures 1-7 Based on embodiment 1, a rotating assembly 5 is assembled at the upper end of the housing 1. The rotating assembly 5 includes a dustproof box 51, which is fixedly connected to the upper end of the housing 1. A telescopic rod 52 and a toothed ring 55 are rotatably connected to the bottom of the dustproof box 51. An electromagnetic support seat 53 is fixedly connected to the top of the telescopic rod 52. A ratchet 54 is fixedly sleeved on the bottom outer wall of the telescopic rod 52. A pawl 56 is rotatably connected to the inner side of the toothed ring 55. A connecting rod 57 is fixedly connected to the outer wall of the moving rod 45. A strip toothed plate 58 is fixedly connected to the bottom of the connecting rod 57.
[0032] A spring 59 is fixedly connected to the inner side of the toothed ring 55. The other end of the spring 59 is fixedly connected to the pawl 56. The spring 59 can provide continuous elastic pressure to the pawl 56, ensuring that the pawl 56 is always tightly engaged with the tooth groove of the ratchet 54, and avoiding slippage during transmission.
[0033] The toothed plate 58 is located on the side of the toothed ring 55 and meshes with the toothed ring 55. The meshing design ensures that the two can cooperate precisely during movement.
[0034] In use, after the initial grinding is completed, the outward movement of the moving rod 45 will cause the connecting rod 57 to move outward. At this time, the toothed plate 58 located at the other end of the connecting rod 57 will also move, and the toothed ring 55 that meshes with it will rotate accordingly. However, at this time, the toothed ring 55 will not drive the ratchet 54 to rotate through the pawl 56. When the moving rod 45 moves back to the center, The toothed plate 58 will push the toothed ring 55 to rotate in the opposite direction. At this time, the pawl 56 on the inner side of the toothed ring 55 will engage with the ratchet 54 under the action of the spring 59, thereby driving the ratchet 54 and the telescopic rod 52 to rotate at a certain angle. The electromagnetic support seat 53 at the top of the telescopic rod 52 will rotate accordingly, so that the unpolished area of the steel ball will rotate to the bottom of the polishing belt 73, realizing automatic switching of polishing at different angles of the steel ball. There is no need to manually adjust the position of the steel ball, which improves polishing efficiency and automation.
[0035] Example 3, please refer to Figures 1-7 Based on embodiment 1, a lifting control assembly 6 is mounted on the side of the movable plate 72. The lifting control assembly 6 includes a connecting block 61, which is fixedly connected to the outer wall of the movable plate 72. A linkage plate 62 is fixedly connected to the other side of the connecting block 61. A guide groove 63 is provided on the inner side of the linkage plate 62. A ring 64 is rotatably connected to the outer wall of the telescopic rod 52 through a bearing. A slide rod 65 is fixedly connected to the outer wall of the ring 64.
[0036] The end of the slide rod 65 away from the ring 64 is slidably connected inside the guide groove 63. The sliding fit between the slide rod 65 and the guide groove 63 not only ensures the stability of the structure, but also provides it with precise guidance.
[0037] In use, the electromagnetic support base 53 is used to support the steel ball before it is clamped by the limiting covers A44 and B46 on both sides. After the steel ball is fixed, in order to avoid wear on the electromagnetic support base 53 caused by the rotation of the steel ball, when the electric slide rail 71 drives the moving plate 72 to move towards the steel ball, the linkage plate 62, which is fixedly connected to its side by the connecting block 61, will also move accordingly. Since the slide rod 65 is slidably connected to the inside of the guide groove 63 opened in the inner wall of the linkage plate 62, the slide rod 65 will slide in the guide groove 63 when the linkage plate 62 moves, and at the same time drive the ring 64 and the telescopic rod 52 to move down as a whole, so that the electromagnetic support base 53 is disengaged from the bottom of the steel ball, effectively avoiding frictional wear between the steel ball and the support base during the rotation process, and extending the service life of the device. After grinding is completed, the electric slide rail 71 drives the moving plate 72 to reset, the linkage plate 62 moves in the opposite direction synchronously, the slide rod 65 slides in the opposite direction along the guide groove 63, the telescopic rod 52 moves upward under its own reset elastic force, and the electromagnetic support seat 53 re-supports the steel ball, which facilitates subsequent material handling operations.
[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
