[0055] In an optional embodiment, if Figure 1 As shown, the first adapter 201 and the second adapter 202 are both configured as a rotating body mechanism. This configuration allows the center of gravity of the overall floating connection mechanism to be along the central axis direction of the first adjustment component on the center side, thereby improving the ability of the first adapter 201 to receive reliable force transmission from the sports device 1 and the second adapter 202 to receive reliable force transmission from the polished surface, which is beneficial to improving the stability of the overall mechanism.

[0056] In an optional embodiment, if Figures 3 to 5 As shown, the first adjustment component includes a first elastic member 301, a guide column 302 and a guide sleeve structure. The first elastic member 301 is sleeved and installed on the outside of the guide column 302. One end of the first elastic member 301 abuts against the guide sleeve structure, and the other end of the first elastic member 301 abuts against the second adapter 202. The first elastic member 301 is suitable for acting on the guide sleeve structure to move away from the second adapter 202.

[0057] The floating connection mechanism provided in this embodiment has one end of the guide column 302 fixedly connected to the second adapter 202 for the first adjustment component on the center side, and the other end is slidably arranged with the guide sleeve structure. When the fluctuating vibration force is transmitted to the grinding surface, the second adapter 202 drives the guide column 302 to move, and the guide column 302 and the guide sleeve structure slide relative to each other. The first elastic member 301 elastically acts on the second adapter 202 and the guide sleeve structure, and the elastic compensation mechanism is used to compensate for the fluctuation of the uneven surface of the workpiece on the grinding surface on the center side, thereby improving the stability of the center side.

[0058] In an optional embodiment, if Figure 5 As shown, the guide sleeve structure includes a first guide sleeve 303 and a second guide sleeve 304 . The first guide sleeve 303 is fixedly connected to the guide post 302 . The first guide sleeve 303 is sleeved on the outside of the guide post 302 . The second guide sleeve 304 is fixedly configured with the first adapter 201 in a limited position.

[0059] The floating connection mechanism provided in this embodiment has a guide sleeve structure that is split into a first guide sleeve 303 and a second guide sleeve 304. The first guide sleeve 303 is fixed to the guide post 302, and the second guide sleeve 304 is fixed to the first adapter 201. The relative sliding between the first guide sleeve 303 and the second guide sleeve 304 replaces the relative sliding between the guide post 302 and the first adapter 201, which is beneficial for increasing the limiting guide area and strengthening the alignment of the guide post 302 in the extension direction.

[0060] In an optional embodiment, the guide sleeve structure is configured as a ball guide sleeve, and a rolling ball is arranged between the first guide sleeve 303 and the second guide sleeve 304 to promote flexible relative sliding between the first guide sleeve 303 and the second guide sleeve 304.

[0061] In an optional embodiment, if Figure 4 As shown, the guide column 302 has an assembly portion and a sliding portion, and the assembly portion is clamped with the second adapter 202 by a step structure. In a specific embodiment, one end of the first elastic member 301 is fixedly connected to the second adapter 202 facing the side of the first adapter 201, and the other end of the first elastic member 301 is fixedly connected to the first guide sleeve 303 in the guide sleeve structure. This configuration can make the assembly portion of the guide column 302 fit tightly with the second adapter 202 through the elastic action of the first elastic member 301, thereby enhancing the assembly accuracy.

[0062] In an optional embodiment, the second adjustment component includes a second elastic member 401, a guide shaft 402 and a linear bearing 403. The second elastic member 401 is sleeved and installed on the outside of the guide shaft 402. The guide shaft 402 is slidably installed in the linear bearing 403. The linear bearing 403 is detachably connected to the first adapter 201. One end of the second elastic member 401 abuts against the linear bearing 403, and the other end of the second elastic member 401 abuts against the second adapter 202. The second elastic member 401 is suitable for acting to move the linear bearing 403 away from the second adapter 202.

[0063] The floating connection mechanism provided in this embodiment has one end of the guide shaft 402 fixed to the second adapter 202 and the other end sliding with the linear bearing 403 for the second adjustment component on the outer peripheral side. When the grinding surface transmits the fluctuating vibration force, the second adapter 202 drives the guide shaft 402 to move, and the guide shaft 402 and the linear bearing 403 slide relative to each other. The first elastic member 301 elastically acts on the second adapter 202 and the guide sleeve structure, and the second elastic member 401 elastically acts on the second adapter 202 and the linear bearing 403. The elastic compensation mechanism can compensate for the fluctuation of the grinding surface on the outer peripheral side caused by the uneven surface of the workpiece, thereby improving the stability of the outer peripheral side.

[0064] In an optional embodiment, if Figure 6 and Figure 7 As shown, the second adjustment component also includes a fixing ring 404 and a clamp 405 . The fixing ring 404 is sleeved on the end of the guide shaft 402 away from the second adapter 202 . The fixing ring 404 and the linear bearing 403 are limited and fixedly arranged, and the clamp 405 is sleeved on the linear bearing 403 .

[0065] The floating connection mechanism provided in this embodiment fixes the linear bearing 403 and the first adapter 201 through a fixing ring 404, and strengthens the limit between the fixing ring 404 and the linear bearing 403 through a retaining ring, thereby improving the assembly accuracy; by using the fixing ring 404 and the retaining ring to fix the linear bearing 403, the user can actively adjust the relative position of the linear bearing 403 and the second adapter 202 according to needs, so as to actively adjust the pre-tightening elastic force of the second elastic member 401 between the linear bearing 403 and the second adapter 202, which is beneficial to improving the flexibility of the floating adjustment of the mechanism.

[0066] For the description of the first motion gap, Figure 4For example, a storage space for accommodating the guide sleeve structure and part of the guide post 302 is provided in the first adapter 201, and the distance between the guide post 302 and the inner wall surface of the storage space is set to a first movement gap. The guide post 302 and the inner wall surface of the storage space have two limit points, an upper limit point and a lower limit point. When the grinding surface is affected by the uneven surface of the workpiece, the guide post 302 can move between the upper limit point and the lower limit point; the upper limit point is the maximum displacement of the guide post 302 sliding upward when the first elastic member 301 is compressed, and the lower limit point is the maximum displacement of the guide post 302 sliding downward when the first elastic member 301 is reset. In some embodiments, a buffer layer can be provided on the inner wall surface of the storage space to stop the upward movement of the guide post 302 at the upper limit point.

[0067] For the description of the second motion gap, Figure 4 and Figure 5 For example, the second motion gap can be directly formed by the linear bearing 403, and the linear bearing 403 can make linear reciprocating motion relative to the guide shaft 402; of course, the guide shaft 402 can be designed to be limited, for example, a limit block can be added on the path of the guide shaft 402 to change the second motion gap.

[0068] As a preferred embodiment, the elastic coefficient of the first elastic member 301 is smaller than the elastic coefficient of the second elastic member 401. The first elastic member 301 and the second elastic member 401 have different elastic coefficients. The elastic coefficient of the first elastic member 301 is set to be smaller than the elastic coefficient of the second elastic member 401, so that the elastic compensation ability of the first adjustment component on the center side of the mechanism is better than the elastic compensation ability of the second adjustment component on the periphery side. When the vibration force of the fluctuation is transmitted on the grinding surface, the force can be transmitted to the center side for elastic absorption, reducing the influence of uneven fluctuations, which is conducive to improving the overall elastic compensation synchronization ability and stability.

[0069] As a further preferred embodiment, the first movement gap for sliding adjustment of the first adjustment component provided on the first adapter 201 is smaller than the second movement gap for sliding adjustment of the second adjustment component provided on the first adapter 201. The first movement gap is set to be smaller than the second movement gap, so that the elastic compensation range of the first adjustment component on the center side of the mechanism is smaller than the elastic compensation range of the second adjustment component on the periphery side, avoiding the center side from excessively absorbing fluctuations and affecting the overall stability; when the elastic coefficient of the first elastic member 301 is smaller than the elastic coefficient of the second elastic member 401, the second adjustment component on the periphery side absorbs more fluctuations and forces, and the influence of the uneven surface of the workpiece on the grinding operation is weakened as much as possible, and the elastic compensation synchronization ability and stability of the overall floating part are improved, so as to avoid damage to the workpiece or the grinding equipment 6.

The first clamping member 501 and the second clamping member 502 are jointly enclosed to form a clamping space, and the clamping space is suitable for assembling the grinding device 6 .

[0071] The floating connection mechanism provided in this embodiment forms a clamping space for assembling the grinding device 6 through the first clamping member 501 and the second clamping member 502, and transmits the fluctuation and force of the grinding processing surface on the grinding device 6 to the floating part to perform elastic compensation and optimize the flexible grinding processing performance of the mechanism.

[0072] In a specific embodiment, the clamping assembly 5 further includes a locking member, and a plurality of locking members are provided, through which the first clamping member 501 and the second clamping member 502 are fixed to each other to clamp and assemble the grinding device 6 .

[0073] In an optional embodiment, if Figure 7 As shown, the second adapter 202 is provided with a third mounting hole 2023, which is fixed to the first clamping member 501 by a fastener. There can be multiple third mounting holes 2023, which can be connected to the first clamping member 501 by multiple fasteners.

[0074] In an optional embodiment, if Figure 8 As shown, the first clamping member 501 includes a clamping portion 5011, an extension portion 5012 and a connecting portion 5013 that are fixedly connected. The clamping portion 5011 is arranged toward the second clamping member 502, and the extension portion 5012 is arranged between the clamping portion 5011 and the connecting portion 5013. The connecting portion 5013 and the second adapter 202 are detachably connected.
