[0059] The floating connection mechanism provided by the embodiment is used for the guide sleeve structure, which is divided into a first guide sleeve 303 and a second guide sleeve 304, the first guide sleeve 303 is fixed with the guide column 302, and the second guide sleeve 304 is fixed with 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 column 302 and the first adapter 201, which is beneficial to increase the limiting and guiding area and strengthen the alignment of the extension direction of the guide column 302.

[0061] In an alternative embodiment, as shown in Figure 4 The guide column 302 has an assembly part and a sliding part, the assembly part is limitingly connected with the second adapter 202 through the stepped structure; in a specific embodiment, one end of the first elastic member 301 is fixedly connected with the second adapter 202 on the side facing the first adapter 201, and the other end of the first elastic member 301 is fixedly connected with the first guide sleeve 303 in the guide sleeve structure, in this way, the assembly part of the guide column 302 is tightly attached with the second adapter 202 through the elastic action of the first elastic member 301, and the assembly precision is improved.

[0062] In an alternative embodiment, the second adjusting assembly comprises a second elastic member 401, a guide shaft 402, and a linear bearing 403. The second elastic member 401 is sleeved on the outside of the guide shaft 402, and the guide shaft 402 is slidingly installed in the linear bearing 403. The linear bearing 403 is detachably connected with 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.

[0063] The floating connection mechanism provided in the embodiment is used for the second adjusting assembly on the outer periphery. One end of the guide shaft 402 is fixed to the second adapter 202, and the other end is slidingly connected with the linear bearing 403. When the polishing surface transmits the fluctuating vibration force, the second adapter 202 drives the guide shaft 402 to move, and the guide shaft 402 slidingly moves relative to the linear bearing 403. The second elastic member 401 elastically acts on the second adapter 202 and the guide sleeve structure, and the first elastic member 301 elastically acts on the second adapter 202 and the linear bearing 403.

[0064] In an alternative embodiment, as shown in Figure 6 With Figure 7 the second adjusting assembly further comprises a fixing ring 404 and a clamping ring 405. The fixing ring 404 is sleeved on one end of the guide shaft 402 away from the second adapter 202. The fixing ring 404 is limitingly fixed with the linear bearing 403. The clamping ring 405 is sleeved on the linear bearing 403.

[0065] The floating connection mechanism provided in the embodiment fixes the linear bearing 403 with the first adapter 201 through the fixing ring 404, and strengthens the limit between the fixing ring 404 and the linear bearing 403 through the clamping ring, thereby improving the assembly precision. By fixing the linear bearing 403 through the fixing ring 404 and the clamping ring, the user can actively adjust the relative position between the linear bearing 403 and the second adapter 202 according to the demand, actively adjust the pre-tightening elastic force of the second elastic member 401 between the linear bearing 403 and the second adapter 202, and improve the flexibility of the floating adjustment of the mechanism.

[0066] The first movement gap is explained by taking Figure 4For example, the first adapter 201 has a storage space for a guide sleeve structure and part of the guide post 302. The distance between the guide post 302 and the inner wall of the storage space is set as the first movement gap. The guide post 302 and the inner wall 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 unevenness of the workpiece surface, 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 element 301 is compressed, and the lower limit point is the maximum displacement of the guide post 302 sliding downward when the first elastic element 301 is reset. In some embodiments, a buffer pad can be provided on the inner wall of the storage space to stop the upward movement of the guide post 302 at the upper limit point.

[0067] The explanation of the second movement gap is as follows: Figure 4 and Figure 5 For example, the second movement gap can be directly formed by the linear bearing 403, which can perform linear reciprocating motion relative to the guide shaft 402. Of course, the guide shaft 402 can be designed to limit movement, for example, by adding a limiting block on the path of the guide shaft 402 to change the second movement gap.

[0068] In a preferred embodiment, the elastic coefficient of the first elastic element 301 is smaller than that of the second elastic element 401. Since the first elastic element 301 and the second elastic element 401 have different elastic coefficients, setting the elastic coefficient of the first elastic element 301 to be smaller than that of the second elastic element 401 allows the elastic compensation capability of the first adjustment component on the center side of the mechanism to be superior to that of the second adjustment component on the outer periphery side. When transmitting the vibrational force of fluctuations on the grinding surface, the force can be transmitted to the center side for elastic absorption, reducing the impact of uneven fluctuations and improving the overall elastic compensation synchronization capability and stability.

[0069] As a further preferred embodiment, the first movement gap provided on the first adapter 201 for sliding adjustment of the first adjustment component is smaller than the second movement gap provided on the first adapter 201 for sliding adjustment of the second adjustment component. Setting the first movement gap smaller than the second movement gap makes the elastic compensation range of the first adjustment component on the center side of the mechanism smaller than the elastic compensation range of the second adjustment component on the outer periphery side, avoiding excessive absorption of fluctuations on the center side and affecting the overall stability; when the elastic coefficient of the first elastic element 301 is smaller than the elastic coefficient of the second elastic element 401, the second adjustment component on the outer periphery side absorbs more fluctuations and forces, minimizing the impact of unevenness on the surface of the workpiece on the grinding operation, improving the overall floating part's elastic compensation synchronization capability and stability, and avoiding damage to the workpiece or grinding equipment 6.

[0070] In an alternative embodiment, the floating connecting mechanism further comprises a clamping assembly 5 fixedly connected with the second adapter 202, and the clamping assembly 5 is used for clamping and fixing the polishing device 6.

[0076] According to the embodiment of the utility model, on the other hand, a floating polishing device is further provided, as shown in Figure 9 It comprises the motion device 1, the polishing device 6 and the above-mentioned floating connecting mechanism.

Since the floating polishing device comprises the floating connecting mechanism, the same effect is achieved, and thus details are not repeated here.

[0078] In the above description, the motion device 1 can be, for example, a mechanical arm, a two-dimensional / three-dimensional motion module or the like; and the polishing device 6 can be, for example, an angle grinder, a sanding machine or the like.

[0079] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
