Detailed Implementation

[0024] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0025] Example 1:

[0026] Provided such as Figure 1-4 The rotary table cutting fixture shown includes a rotary table 1 and a clamping assembly 2. The rotary table 1 is annular, and slots 11 are evenly distributed along the circumference of the rotary table 1. The slots 11 penetrate the rotary table 1, and the clamping assembly 2 is connected to the slots 11.

[0027] The clamp assembly 2 includes a insert plate 21, a fixed base 22, a handle 23, a connecting rod 24, and a pressure rod 25. The insert plate 21 is connected to the slot 11. The fixed base 22 is fixedly mounted on the insert plate 21. The handle 23 is rotatably connected to the fixed base 22. The pressure rod 25 is rotatably connected to the fixed base 22. Both ends of the connecting rod 24 are rotatably connected to the pressure rod 25 and the handle 23, respectively. The pressure rod 25 is provided with a sliding groove 26, and an adjusting nut 27 is provided on the sliding groove 26. Rotating the handle 23 can drive the pressure rod 25 to rotate via the connecting rod 24. The adjusting nut 27 can slide and lock on the sliding groove 26 to adjust the clamping position. The adjusting nut 27 is threadedly connected to a threaded rod, and a pressure block is provided at the bottom of the threaded rod for clamping the ring-shaped product. The insert plate 21 allows for quick insertion of the inner or outer ring of the rotating table 1 of the clamp assembly 2, facilitating rapid positioning and clamping.

[0028] It also includes a fixing plate 3, on which the rotating platform 1 is fixedly mounted. The fixing plate 3 is used to support the rotating platform 1.

[0029] The rotating platform 1 includes a fixed platform 12, a rotating platform 13, and rotating bearings 14. The fixed platform 12 is fixedly mounted on a fixed plate 3, and several rotating bearings 14 are evenly distributed around the circumference of the fixed platform 12. The rotating platform 13 is connected to the rotating bearings 14. The fixed platform 12 is provided with an opening slot 15. The fixed plate 3 is provided with an inner ring cutting groove 31, one end of which is inside the opening slot 15. The fixed plate 3 is provided with an outer ring cutting groove 32. In this embodiment, there are six rotating bearings 14, evenly distributed around the circumference. The rotating platform 13 is rotated by the rotating bearings 14, which, in conjunction with the opening slot 15 and the inner ring cutting groove 31, allow the diamond wire used for cutting to cut the inner hole of the ring product. The outer ring cutting groove 32 facilitates the cutting of the outer circle of the ring product by the diamond wire.

[0030] It also includes a motor 4 and a drive pulley 5. The motor 4 is connected to the drive pulley 5, and the drive pulley 5 is connected to the rotary table 13 via a belt. It also includes an idler pulley 6, which is located between the drive pulley 5 and the rotary table 13. The motor 4 drives the drive pulley 5 to rotate, and the drive pulley 5 drives the rotary table 13 to rotate via the belt. The idler pulley 6 changes the direction of belt movement, increases the contact area between the belt and the rotary table 13, and enhances the belt's transmission power.

[0031] Working principle: When the outer circle needs to be cut, insert the insert plate 21 of the clamping assembly 2 into the slot 11 of the inner ring of the rotating table 1, and rotate the handle 23 to clamp the ring product. The motor 4 drives the drive wheel 5 to rotate, and the drive wheel 5 drives the rotating table 13 to rotate via a belt. The diamond wire cuts the outer circle of the ring product. After the outer circle is cut, rotate the handle 23 to release the clamping assembly 2, pull out the clamping assembly 2, insert it into the slot 11 of the outer ring of the rotating table 1, and rotate the handle 23 to clamp the ring product, cutting the inner circle of the ring product. When changing the clamping assembly 2, it is done in turn, one clamping assembly 2 is replaced before the next one is replaced, to prevent the ring product from moving and to maintain positioning accuracy.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
