[0031] Please refer to Figure 1-Figure 5 An embodiment of the utility model provides a grinding rod chuck for fluid polishing equipment, which is used to solve the problem that the grinding rod chuck connected by a connecting pin is easy to break.

[0032] For details, please refer to Figure 1 A three-dimensional diagram of a grinding rod chuck for a fluid polishing device provided in an embodiment of the utility model. The utility model provides a grinding rod chuck for a fluid polishing device, which comprises a connecting rod 10 and a connecting sleeve 20 detachably connected to the connecting rod 10. The connecting rod 10 is used to connect the fluid polishing device, and the connecting sleeve 20 is used to connect the fluid polishing fixture 33; see Figure 2, which is an exploded view of a grinding rod chuck of a fluid polishing equipment provided in an embodiment of the utility model. It can be seen from the figure that the connecting rod 10 includes a connecting rod base 11 and a first connecting part 12 fixedly connected to the connecting rod base 11, wherein the cross-section of the first connecting part 12 is a polygon, and the end face of the first connecting part 12 is provided with a first connecting groove 121.

[0033] For further information, see Figure 3 The end of the connecting sleeve 20 is provided with a first accommodating cavity 21 that cooperates with the first connecting portion 12. It should be noted that the cross section of the first connecting portion 12 is a polygon, and the first accommodating cavity 21 cooperates with the first connecting portion 12 to be connected. The cross section of the first accommodating cavity 21 is also a polygon. By setting the cross section of the first connecting portion 12 and the cross section of the first accommodating cavity 21 to be polygonal, the connection between the first connecting portion 12 and the first accommodating cavity 21 is made tighter, and the connection between the first connecting portion 12 and the first accommodating cavity 21 is evenly stressed. In addition, the polygonal cross section can avoid the first connecting portion 12 from being too tight. A connecting portion 12 slides relative to the first accommodating cavity 21, and a first connecting hole 211 is provided at the bottom of the first accommodating cavity 21 corresponding to the first connecting groove 121. The first connecting member 31 passes through the first connecting hole 211 and is connected to the first connecting groove 121. Preferably, the first connecting member 31 is an M12 screw, and the first connecting member 31 passes through the first connecting hole 211 and is connected to the first connecting groove 121 to achieve a fixed connection between the connecting rod 10 and the connecting sleeve 20, thereby ensuring the connection stability between the connecting rod 10 and the connecting sleeve 20 and preventing the connecting rod 10 and the connecting sleeve 20 from falling off and damaging the fixture due to unstable connection.

[0034] The utility model provides a grinding rod chuck for fluid polishing equipment. The connecting rod 10 includes a first connecting portion 12, and a first accommodating cavity 21 cooperating with the first connecting portion 12 is arranged at the end of the connecting sleeve 20, so as to realize the cooperative connection between the connecting rod 10 and the connecting sleeve 20. In addition, the cross section of the first connecting portion 12 is a polygon, which ensures that when the grinding rod chuck for fluid polishing equipment is performing a polishing operation, the connecting rod 10 and the connecting sleeve 20 will not produce circumferential relative sliding. The first connecting member 31 is arranged to pass through the first connecting hole 211 and connect the first connecting groove 121, so as to realize axial locking of the connecting rod 10 and the connecting sleeve 20, avoid the connecting rod 10 and the connecting sleeve 20 falling off from each other to cause damage to the product appearance and damage to the fixture, and eliminate safety hazards.

[0035] As a further improvement of the present invention, the first connecting portion 12 is a polygonal prism, and the cross-section of the first connecting portion 12 at one end away from the connecting rod base 11 is smaller than the cross-section of the first connecting portion 12 at one end close to the connecting rod base 11. It should be noted that the first accommodating cavity 21 is cooperatively connected with the first connecting portion 12, and the first accommodating cavity 21 is also a polygonal prism-shaped cavity, so that the first connecting portion 12 is accommodated in the first accommodating cavity 21. By setting the first connecting portion 12 to be a polygonal prism, and the cross-section of the first connecting portion 12 at one end away from the connecting rod base 11 is smaller than the cross-section of the first connecting portion 12 at one end close to the connecting rod base 11, it can be achieved that when the connecting rod 10 is cooperatively installed with the connecting sleeve 20, the end of the first connecting portion 12 away from the connecting rod base 11 can smoothly penetrate into the first cavity of the connecting sleeve 20. Inside the accommodating cavity 21, the first connecting portion 12 is a polygonal prism, and the first accommodating cavity 21 is a polygonal prism-shaped cavity. This can ensure that the first connecting portion 12 and the first accommodating cavity 21 are subjected to uniform circumferential force during the polishing process of the fluid polishing equipment, and will not break due to excessive force on a certain part. In addition, the coordinated setting of the polygonal prism and the polygonal prism-shaped cavity strengthens the depth of the circumferential offset limit through the depth of the prism, and further ensures that during the polishing process of the fluid polishing equipment, the connecting rod 10 and the connecting sleeve 20 will not be relatively offset, thereby ensuring the connection stability of the connecting rod 10 and the connecting sleeve 20.

[0036] As a further improvement of the present invention, the cross section of the first connection part 12 is a regular polygon. It should be noted that the cross section of the first connection part 12 is a regular polygon with a polygonal number of sides not less than 3. Preferably, the cross section of the first connection part 12 is a regular hexagon. By setting the cross section of the first connection part 12 to be a regular polygon, the first accommodating chamber 21 is cooperatively connected with the first connection part 12, and correspondingly, the cross section of the first accommodating chamber 21 is also a regular polygon. By setting the cross section of the first connection part 12 and the cross section of the first accommodating chamber 21 to be regular polygons, it can be further ensured that the force at the connection between the first connection part 12 and the first accommodating chamber 21 is uniform, and the circumferential force of the first connection part 12 and the first accommodating chamber 21 is further strengthened during the polishing process of the fluid polishing equipment. Uniform force is avoided to avoid fracture due to uneven force.

[0037] As a further improvement of the present invention, the connecting rod base 11 is provided with a second connecting groove 111, the second connecting groove 111 is sleeved with a first flange 1111 and a second flange 1112, the end of the connecting sleeve 20 is provided with a first connecting ring 22, the first connecting ring 22 is evenly provided with second connecting holes 221, and the second connecting member 32 penetrates the second connecting holes 221 to respectively connect the first flange 1111 and the second flange 1112. Preferably, eight second connecting holes 221 are evenly provided on the first connecting ring 22, and correspondingly, the eight second connecting members 32 penetrate the eight second connecting holes 221 to respectively connect the first flange 1111 and the second flange 1112, wherein four second connecting members 32 penetrate the four second connecting holes 221 to respectively connect the first flange 1111, and the remaining four second connecting members 32 penetrate the four second connecting holes 221 to respectively connect the second flange 1112, and the second connecting member 32 is an M10 screw, and the second connecting member 32 penetrates the second connecting holes 221 to respectively connect the first flange 1111 and the second flange 1112. 111 and the second flange 1112 realize the connection between the connecting rod 10 and the connecting sleeve 20, further strengthening the connection tightness between the connecting rod 10 and the connecting sleeve 20. At the same time, the split arrangement of the first flange 1111 and the second flange 1112 overcomes the space limitation, and prevents the first flange 1111 and the second flange 1112 from being misaligned while being separated. The first flange 1111 and the second flange 1112 will not generate friction with the connecting rod 10, and can be installed in the second connecting groove 111 in parallel and smoothly, without causing damage to the first flange 1111, the second flange 1112 and the connecting rod 10.

[0038] As a further improvement of the present invention, see Figure 4-5 The end of the connecting sleeve 20 away from the connecting rod 10 is provided with a second accommodating chamber 23 for accommodating the fluid polishing jig 33, and the end surface of the second accommodating chamber 23 is provided with a limiting groove 231. By providing the limiting groove 231 on the end surface of the second accommodating chamber 23, the fluid polishing jig 33 can be limited and positioned in coordination with the fluid polishing jig 33, so as to avoid the fluid polishing jig 33 being positioned inaccurately and affecting the polishing effect.

[0039] As a further improvement of the present utility model, a latch 241 fixing block 24 is provided on the side wall of the connecting sleeve 20, a latch 241 is fixed in the latch 241 fixing block 24, and a fixing hole 242 is provided on the connecting sleeve 20 corresponding to the latch 241, and the latch 241 penetrates through the fixing hole 242 to fix the fluid polishing jig 33. By providing a latch 241 fixing block 24 on the side wall of the connecting sleeve 20, the latch 241 fixed in the latch 241 fixing block 24 penetrates through the fixing hole 242 to insert the fluid polishing jig 33, so as to achieve the fixation of the fluid polishing jig 33, ensure the fixation effect of the fluid polishing jig 33, and also facilitate the disassembly, assembly and fixation of the fluid polishing jig 33, shorten the replacement time of the fluid polishing jig 33, and improve the polishing efficiency.

[0040] As a further improvement of the present invention, a second connecting ring 112 is provided at one end of the connecting rod 10 away from the first connecting portion 12, and a rotating member 13 is rotatably connected between the second connecting ring 112 and the first connecting groove 121. A bearing 131 is provided between the rotating member 13 and the connecting rod 10. The rotating connection between the rotating member 13 and the connecting rod 10 is achieved by providing the bearing 131, and the bearing 131 includes a first bearing 1311 and a second bearing 1312, and the first bearing 1311 and the second bearing 1312 are respectively provided at both ends of the rotating member 13. The provision of the first bearing 1311 and the second bearing 1312 ensures the stability of the rotating connection between the rotating member 13 and the connecting rod 10.

[0041] As a further improvement of the present invention, a fastener 14 is provided between the rotating member 13 and the first connecting groove 121.
