With the continuous improvement of sealing performance requirements in industrial systems, the standards for the spherical accuracy and surface finish of floats are also constantly increasing, placing higher demands on grinding processes and equipment.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] like Figures 1-3 As shown, a float valve grinding device according to one embodiment of the present invention includes a machine base 1, a moving device 2, a swing arm device 3, a placement device 4, and a grinding machine 5; the moving device 2 is mounted on the machine base 1; the swing arm device 3 is mounted on the moving device 2; the placement device 4 is mounted on the machine base 1, the placement device 4 is used to place the float and drive the float to rotate, the moving device 2 is used to drive the swing arm device 3 to move away from and closer to the placement device 4; the grinding machine 5 is mounted on the swing arm device 3, the swing arm device 3 is used to control the grinding angle of the grinding machine 5.

[0032] The aforementioned float valve grinding equipment uses a precision linear guide rail and servo drive system of the moving device 2 to move the swing arm device 3, whose stroke range can cover floats of different diameters. A swing device is included to facilitate adjustment of the grinding angle of the grinding machine 5. The placement device 4 drives the float to rotate, while the grinding machine 5 grinds at a set angle, ensuring that the surface of the float is uniformly and consistently treated, avoiding the instability of manual operation. This float valve grinding equipment solves the problem of traditional equipment where the grinding head cannot cover the entire outer surface of the float.

[0033] like Figures 1-2As shown, in one embodiment, the moving device 2 includes a first linear module 21 and a support frame 22. The first linear module 21 is mounted on the machine base 1, and the support frame 22 is mounted on the moving end of the first linear module 21. Thus, by using the first linear module 21 as the core of the moving device 2, high-precision, high-rigidity, and stable and reliable linear motion is provided. The support frame 22 is fixed to the moving end of the module, providing a stable mounting base for the swing arm device 3. This structure ensures precise, repeatable, and smooth adjustment of the grinding machine 5 relative to the float position, facilitating adaptation to different ball diameters and precise positioning.

[0034] like Figures 1-3 As shown, in one embodiment, the placement device 4 includes a first rotation mechanism 41 and a second rotation mechanism 42; both the first rotation mechanism 41 and the second rotation mechanism 42 are mounted on the machine base 1, and the first rotation mechanism 41 is used for placing the float; the first rotation mechanism 41 includes a turntable 411 and a first motor 412; the first motor 412 is mounted on the machine base 1, and its output end is connected to the turntable 411, and the first motor 412 is used to drive the turntable 411 to rotate; the turntable 411 is provided with multiple support components; the multiple support components are arranged around the rotation axis of the turntable 411; the multiple support components cooperate to support the float; the support components include a support base 413 and a roller 414; the support base 413 is mounted on the turntable 411, and the roller 414 is mounted on the support base 413 and rotatably connected to the support base 413; the roller 414 is inclined. Thus, the first motor 412 drives the turntable 411 to rotate, causing multiple support components on it to revolve around an axis. The support components employ a structure with an inclined roller 414. When the float is placed on it, the inclined roller 414, while revolving with the turntable 411, naturally induces the float to rotate due to its tilt angle. This design utilizes the tilting friction of the roller 414 to achieve float rotation, resulting in a simple and reliable structure. Multiple circumferentially distributed support components provide uniform support. The inclined roller 414 reduces sliding friction between the ball and the support points, lowers the risk of scratches on the ball surface, and promotes smoother and more stable ball rotation, providing a foundation for uniform grinding.

[0035] like Figures 1-3As shown, in one embodiment, the second rotation mechanism 42 includes a base 421, a second motor 422, and a rotating wheel 423. The base 421 is mounted on the machine platform 1, and the second motor 422 is mounted on the base 421. The output end of the second motor 422 is connected to the rotating wheel, and the second motor 422 is used to drive the rotating wheel to rotate. Thus, the independent rotating wheel is driven to rotate by the second motor 422. This mechanism is usually used in conjunction with the first rotation mechanism 41 to assist or enhance the rotational power of the float through friction drive or other means. Setting up the second rotation mechanism 42 can significantly improve the torque and stability of driving the float to rotate, especially for larger or heavier floats, ensuring that the float can overcome grinding resistance and rotate continuously and stably during the grinding process, further improving the uniformity and efficiency of grinding.

[0036] like Figures 1-3 As shown, in one embodiment, the swing arm device 3 includes a rotating rod 31, a first connecting arm 32, a second connecting arm 33, and a first cylinder 34. The rotating rod 31 passes through the first connecting arm 32, is inserted into the support frame 22, and is rotatably connected to the support frame 22. One end of the second connecting arm 33 is hinged to the first connecting arm 32, and the grinding machine 5 is located at the other end of the second connecting arm 33. One end of the first cylinder 34 is hinged to the first connecting arm 32, and the other end of the first cylinder 34 is hinged to the second connecting arm 33. The swing arm device 3 also includes a first hinge block 35, a second hinge block 36, and a second linear module 37. The first hinge block 35 is located on the support frame 22, and the second hinge block 36 is located at the bottom of the second linear module 37. The first hinge block 35 and the second hinge block 36 are hinged together. The moving end of the second linear module 37 is hinged to the first connecting arm 32. Thus, this structure enables flexible and precise control of the grinding machine 5 with multiple degrees of freedom. Rotating rod 31 provides rotational freedom about the vertical axis. First cylinder 34 drives the relative angle between first connecting arm 32 and second connecting arm 33, directly controlling the grinding angle of the grinder 5. Second linear module 37 adjusts the horizontal extension distance or height of the grinder 5 by pushing the first connecting arm 32. The hinge between first hinge block 35 and second hinge block 36 provides necessary installation and motion compensation. This combined design allows the grinder 5 to not only move as a whole with the moving device 2, but also to independently and precisely adjust its working angle and position, ensuring that the grinding head contacts and covers different areas of the sphere at the optimal angle. It is the core mechanism for achieving comprehensive and uniform grinding.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
