[0031] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Example 1

[0034] Please refer to Figure 1 As shown, a high-performance split ring for transmission connection is used to connect a machine tool spindle and a workpiece to be machined;

[0035] Specifically, a spindle connecting member 1 is coaxially connected to the machine tool spindle, and the spindle connecting member 1 is driven to rotate by the machine tool spindle; the workpiece to be processed is coaxially connected to the spindle connecting member 1 through the workpiece mounting member 2, so that the rotation of the machine tool spindle drives the workpiece to be processed to rotate, thereby processing the workpiece to be processed; it also includes a mounting seat 23, which serves as a base for connecting the spindle connecting member 1 and the workpiece mounting member 2. The mounting seat 23 and the workpiece mounting member 2 constitute a workpiece mounting assembly. The mounting seat 23 is connected to the spindle connecting member 1, and then the workpiece mounting member 2 is connected to the mounting seat 23. The rotation of the machine tool spindle can drive the spindle connecting member 1, the mounting seat 23 and the workpiece mounting member 2 to rotate;

[0036] Furthermore, a second receiving groove is provided on one side of the mounting seat 23 for receiving the spindle connector 1. A tapered section 4 is provided on the other side of the mounting seat 23. The tapered section 4 is coaxial with the spindle connector 1, and the diameter of the tapered section 4 gradually decreases as it moves away from the mounting seat 23.

[0037] Furthermore, the axis of the spindle connector 1 extends along the first direction, and the spindle connector 1 has a mounting section and a connecting section 3 in sequence along the first direction, wherein the mounting section is used to connect with the machine tool spindle; a through hole is provided on the mounting seat 23 along the first direction, and there are multiple through holes, and the connecting section 3 extends through the through hole to the other side of the mounting seat 23, and the first direction is Figure 1 mid-horizontal direction;

[0038] Furthermore, a through opening is provided in the middle of the workpiece to be processed, which is sleeved on the workpiece mounting member 2 through the through opening, thereby completing the connection between the workpiece to be processed and the workpiece mounting member 2. A first receiving groove is provided on the workpiece mounting member 2 corresponding to the conical section 4. By sleeve-fitting the first receiving groove on the conical section 4, the conical section 4 pushes the first receiving groove, causing the workpiece mounting member 2 to expand, so that the circumferential side wall of the workpiece mounting member 2 can press against the circumferential inner wall of the through opening, thereby making the connection between the workpiece to be processed and the workpiece mounting member 2 tighter.

[0039] Furthermore, the workpiece mounting member 2 is coaxially connected to the spindle connecting member 1 through the high-performance open ring for transmission connection. The high-performance open ring for transmission connection applies axial traction to the workpiece mounting member 2 and the spindle connecting member 1, so that the workpiece mounting member 2 and the spindle connecting member 1 tend to approach each other, thereby pushing the first accommodating groove through the tapered section 4, causing the workpiece mounting member 2 to expand, strengthening the connection between the workpiece mounting member 2 and the spindle connecting member 1, and driving the spindle connecting member 1 to rotate through the spindle, thereby driving the workpiece mounting member 2 and the workpiece to rotate, thereby enabling the workpiece to be processed;

[0040] Furthermore, a first groove is provided on the circumferential side wall of the connecting section 3 of the spindle connecting member 1, and an annular boss 5 is fixedly provided on one end of the workpiece mounting member 2 close to the spindle connecting member 1, and the side wall of the annular boss 5 close to the spindle connecting member 1 and the side wall of the connecting section 3 close to the workpiece mounting member 2 are abutted.

[0041] like Figure 2 and Figure 3 As shown, a high-performance split ring for transmission connection comprises:

[0042] The open ring body 6 is an annular structure, and its axis extends along the first direction. The inner walls of the open ring body at both ends in the first direction respectively have a first protrusion and a second protrusion. The first protrusion is used to be clamped in the first groove, and the side wall of the second protrusion close to the first protrusion is used to abut the side wall of the annular boss 5 away from the spindle connection member 1. As a result, the open ring body 6 can apply axial traction to the spindle connection member 1 and the workpiece mounting member 2, so that the spindle connection member 1 and the workpiece mounting member 2 tend to approach each other, thereby clamping the spindle connection member 1 and the workpiece mounting member 2;

[0043] Furthermore, a second groove 20 is formed between the first protrusion and the second protrusion of the open ring body 6 for accommodating an end of the connecting section 3 close to the workpiece mounting member 2 and the annular boss 5 ; the open ring body 6 has an opening 9 .

[0044] The open ring body 6 comprises:

[0045] The first ring petal 7 is an arc-shaped structure, and its two ends are respectively a first end and a second end;

[0046] The second ring petal 8 is an arc-shaped structure, and its two ends are respectively a third end and a fourth end;

[0047] The first ring petal 7 and the second ring petal 8 are connected to each other, and the first end and the third end are hingedly connected, and an opening 9 is formed between the second end and the fourth end.

[0048] Furthermore, the first end and the third end are hingedly connected via a hinge 10;

[0049] Specifically, if Figure 5 and Figure 6 As shown, a third groove is formed at the first end, a fourth groove is formed at the third end, a first pin hole 11 is formed through the first end along the first direction, and the first pin hole and the third groove are connected, a second pin hole 12 is formed through the third end along the first direction, and the second pin hole and the fourth groove are connected, and a hinge 10 is provided in both the third and fourth grooves;

[0050] Furthermore, the hinged member 10 has a fifth end and a sixth end at its two ends, which are located inside the third groove and the fourth groove, respectively. The fifth end is provided with a third pin hole along the first direction, and the sixth end is provided with a fourth pin hole along the first direction. The third pin hole and the first pin hole 11 are coaxially arranged, and the fourth pin hole and the second pin hole 12 are coaxially arranged. The first pin shaft passes through the first pin hole 11 and the third pin hole, and the second pin shaft passes through the second pin hole 12 and the fourth pin hole. Thus, a hinged connection is achieved between the first and third ends, so that the first ring petal 7 can rotate around the first pin shaft, and the second ring petal 8 can rotate around the second pin shaft, thereby opening the open ring body 6.

[0051] Furthermore, in other embodiments, Figure 4 As shown, a rotating block 13 is provided at the first end, and a fifth groove is provided at the third end. The fifth groove is adapted to the rotating block 13. A fifth pin hole is formed through the rotating block 13 along the first direction. A sixth pin hole is formed through the third end. The sixth pin hole is connected to the fifth groove. The third pin shaft rotates through the fifth and sixth pin holes, thereby realizing a hinged connection between the first and third ends. The first and second ring petals 7, 8 can rotate about the third pin shaft, thereby opening the open ring body 6.

[0052] It should be noted that after the first and second pin shafts are installed, or the third pin shaft is installed, in order to prevent it from falling out, glue or the like may be used to block the first pin hole 11 and the second pin hole, or the sixth pin hole.

[0053] like Figure 5 and Figure 6 As shown, a first protrusion 14 and a second protrusion 15 are fixedly provided on the inner walls of both ends of the first ring petal 7 in the first direction, respectively. The first protrusion 14 and the second protrusion 15 are both arc-shaped structures, and a first recessed portion 16 is formed between the first protrusion 14 and the second protrusion 15;

[0054] A third protrusion 17 and a fourth protrusion 18 are fixedly provided on the inner walls of both ends of the second ring petal 8 in the first direction. Both the third protrusion 17 and the fourth protrusion 18 are arc-shaped structures, and a second recessed portion 19 is formed between the third protrusion 17 and the fourth protrusion 18.

[0055] The first recessed portion 16 and the second recessed portion 19 together form a second groove 20, the first raised portion 14 and the third raised portion 17 are on the same side, forming a first convex block, and the first raised portion 14 and the third raised portion 17 are coplanar with the side wall close to the second groove 20; the second raised portion 15 and the fourth raised portion 18 are on the same side, forming a second convex block, and the second raised portion 15 and the fourth raised portion 18 are coplanar with the side wall close to the second groove 20, thereby ensuring that when axial traction is applied to the spindle connector 1 and the workpiece mounting member 2 through the open ring body 6 and the spindle connector 1 and the workpiece mounting member 2 are connected, the workpiece mounting member 2 will not deviate, thereby avoiding deviation when the workpiece to be processed is installed, and further avoiding defects or even scrap in subsequent processing;

[0056] It should be noted that in order to ensure that the side walls of the first protrusion 14 and the third protrusion 17 close to the second groove 20 are coplanar and the side walls of the second protrusion 15 and the fourth protrusion 18 close to the second groove 20 are coplanar, that is, to ensure the flatness of the first protrusion close to the second groove 20 and the flatness of the second protrusion close to the second groove 20, the first ring petal 7 and the second ring petal 8 must be cut from a whole ring material.

[0057] Two through holes 21 are formed on the open ring body 6 along the first direction, and a limiting groove is formed on the side wall of the mounting seat 23 corresponding to the through hole 21. A limiting hole is formed on the annular boss 5, and the limiting member 22 extends through the limiting hole and the through hole 21 to the limiting groove, thereby limiting the spindle connecting member 1, the workpiece mounting member 2 and the open ring body 6 (such as Figure 1), when in use, the machine tool spindle drives the spindle connector 1, the mounting seat 23, the workpiece mounting member 2 and the open ring body 6 to rotate synchronously to avoid relative movement between the spindle connector 1, the mounting seat 23, the workpiece mounting member 2 and the open ring body 6, resulting in wear or processing of waste; optionally, the type of the limit member 22 is a limit pin.

[0058] It should be noted that the workpiece mounting part 2 has different specifications of the openings corresponding to different workpieces to be processed, while the diameter of the annular boss 5 remains unchanged. Therefore, different workpieces to be processed can be installed by replacing workpiece mounting parts 2 of different specifications, and the workpiece mounting parts 2 of different specifications and the spindle connecting part 1 can be connected through the open ring body 6.

[0059] It should be noted that, according to actual processing conditions, the angle of the hinge 10 can be changed, and the position of the through hole 21 can also be adjusted according to actual processing conditions.

[0060] Working principle: A high-performance open ring for transmission connection, comprising an open ring body, an axial direction of which extends along a first direction, for connecting a spindle connector 1 and a workpiece mounting member 2, the open ring body having a first protrusion and a second protrusion on the inner walls at both ends in the first direction, respectively, a first groove is provided on the spindle connector 1 along the circumferential direction, and an annular boss 5 is provided on the end of the workpiece mounting member 2 close to the spindle connector 1, the first protrusion is used to be clamped in the first groove, and the second protrusion is used to abut against the side wall of the annular boss away from the spindle connector 1, thereby applying axial traction to the spindle connector 1 and the workpiece mounting member 2, thereby being able to clamp the spindle connector 1 and the workpiece mounting member 2, so that the spindle connector 1 and the workpiece mounting member 2 are tightly connected;

[0061] The device has a simple and reasonable structure and is easy to operate. Compared with traditional rubber connections, it does not require mold processing and has a long service life. It firmly connects the spindle connector 1 and the workpiece mounting member 2, reducing the cost of use.
