[0024] like Figure 1-9 As shown, a cemented carbide roller ring blank flipping device includes an adjusting component, an inner ring 3, an outer ring 2, a fixing component 5, and a swivel 9. A plurality of the adjusting components are fixedly connected to the inner ring 3. The outer side of the inner ring 3 is rotatably connected to the inner side of the outer ring 2. The inner side of the inner ring 3 is fixedly connected to one end of a sleeve 4. The other end of the sleeve 4 is rotatably connected to the swivel 9. The sleeve 4 is sleeved on one end of the fixing component 5. The other end of the fixing component 5 is connected to the roller ring blank. Specifically, the outer ring 2 is driven to rotate by rotating the handle 8 disposed on the outside of the outer ring 2, and the outer ring 2 further drives the fixed plate 202 to rotate, so that the traction rope pulls the fixed component 5 to move outward to adapt to the diameter of the roller ring blank (that is, the distance between the two fixed components 5 is greater than the diameter of the roller ring blank), the handle 8 is fixed, the height of the adjustment component is adjusted to adapt to the position of the roller ring blank, the handle 8 is released, and the two fixed components 5 are moved closer to each other under the elastic force of the spring component 6 to fix the roller ring blank, and then the rotating ring is rotated 180° to flip the roller ring blank. It should be noted that, as another embodiment, the adjustment component can also be fixedly connected to the outer ring 2, and of course the corresponding handle 8 must be arranged on the inside of the inner ring 2.

[0025] like Figure 6-8As shown, the adjustment assembly includes a fixed bracket and a fixed frame 7, the fixed bracket includes a base 101 and a bracket 102, the fixed frame 7 includes a fixed block 1 701 and a fixed block 2 702, one side of the fixed block 1 701 is provided with a fixed groove 7011 fixedly connected to the inner ring 3, and the other side is fixedly connected to one end of the fixed block 2 702, and the other end of the fixed block 2 702 is provided with a threaded blind hole 7021, and the top of the base 101 is provided with a bracket 102, one side of the bracket 102 is provided with a slide groove 1021 slidably connected to the fixed block 2 702, and the other side is provided with a through groove 1022 connected to the slide groove 1021, and the through groove 1022 is slidably connected with a screw 10, and the screw 10 is threadedly connected with the threaded blind hole 7021. It should be noted that when the screw 10 is loosened, the fixed frame 7 can slide in the slide groove 1021 to adjust its own height, thereby adjusting the height of the fixed inner ring 3. Here, the fixing bracket 7 is fixed by the squeezing force between the screw 10 and the bracket 102, so a rubber ring can be provided on the screw 10 (located between the screw 10 and the bracket 102) to increase the friction between the two so as to better fix the fixing bracket 7 to the bracket 2.

[0026] like Figure 2 , 4 As shown, the outer side of the inner ring 3 is provided with an annular groove 1 302, and the outer / inner sides of the two walls of the annular groove 1 302 are provided with annular grooves 301, and the inner side of the outer ring 2 is provided with an annular groove 201, and the inner / outer sides of the two walls of the annular groove 201 are provided with an annular slider 204 that can slidably cooperate with the annular groove 301. The positions of the annular grooves 301 and the annular slider 204 on the inner ring 3 and the outer ring 2 can also be interchanged, that is, the annular slider is provided on the inner ring 3, and the annular groove 301 is provided on the outer ring 2, and the two can make relative circular motions through the above two structures.

[0027] like Figure 2 , 4 As shown in , 5, and 9, the fixing assembly 5 is located in the sleeve 4 and fixedly connected to the collar 501 at one end. Two limiting holes 303 communicating with the annular groove 1 302 are symmetrically arranged on the inner side wall of the inner ring 3. The sleeve 4 is connected to the limiting holes 303. Two fixing plates 202 are symmetrically arranged on the inner side wall of the annular groove 201. The fixing plates 202 are provided with through holes. Each fixing plate 202 is provided with a limiting block 1 203. A traction rope (not shown in the figure) is slidably arranged in the through holes and the limiting holes 303. The two ends of the traction rope are respectively fixedly connected to the collar 501 and the limiting block 1 203. There are requirements for the length of the traction rope. When the whole device is in a natural state, the traction rope is in a tight state and the spring 603 is in a compressed state.

[0028] like Figure 5 , 9 As shown, the rotating ring 9 is symmetrically provided with a limiting through hole 901 penetrating both inner and outer sides, and the fixing assembly 5 includes a fixing rod 502. The limiting through hole 901 is rotatably matched with the end of the sleeve 4 away from the inner ring 3, and the fixing rod 502 is slidably matched with the end of the sleeve 4 close to the limiting through hole 901.

[0029] like Figure 1 , 5 As shown in Figure 9, the fixing component 5 is symmetrically provided with two connecting blocks 503 at one end away from the sleeve 4, and each of the limiting through holes 1 901 is provided with limiting through holes 2 902 on both sides.

One end of the guide rod 602 is fixedly connected to the connection block 503, and the other end is fixedly connected to the second stopper 601. It should be noted that the length of the guide rod 602 should be less than the length of the fixed rod 502. The second stopper 601 limits the guide rod 602 from being separated from the second stopper through hole 902. At the same time, since the length of the guide rod 602 is less than that of the fixed rod 502 and the two are fixedly connected, the fixed rod 502 will not be separated from the sleeve 4. The outer diameter of the spring 603 is greater than the diameter of the second stopper through hole 902, so that the spring 603 is limited to the inner side of the rotating ring 9.

[0031] like Figure 5 As shown, a fixing member 504 is fixedly arranged at one end of the fixing assembly 5 away from the sleeve 4, and the fixing member 504 is connected to the roller ring compact. The fixing member 504 should be made of a material with large friction and certain elasticity, such as rubber.

[0032] Working process: place the device on the top of the roller ring blank (the rotating ring 9 and the roller ring blank are coaxial), rotate the turning handle 8 set on the outside of the outer ring 2 to drive the outer ring 2 to rotate, and the outer ring 2 further drives the fixed plate 202 to rotate, so that the traction rope pulls the fixed component 5 to move outward to adapt to the diameter of the roller ring blank (that is, the distance between the two fixed components 5 is larger than the diameter of the roller ring blank), fix the turning handle 8 without moving, adjust the height of the adjusting component to adapt to the position of the roller ring blank, loosen the turning handle 8, and under the elastic force of the spring component 6, the two fixed components 5 approach each other to fix the roller ring blank, then rotate the rotating ring 180° to flip the roller ring blank, rotate the turning handle 8 again to move the fixed component 6 outward so that the fixing part 504 is separated from the roller ring blank, fix the turning handle 8, and then adjust the height of the adjusting component so that the entire device is completely separated from the roller ring blank.

[0033] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
