[0033] Please refer to Figures 1 to 7 , the present invention provides a technical solution:

[0034] Embodiment 1

[0035] A new type of cutting disc, comprising: an annular mounting disc 1, a guide groove 6, and an extrusion block 9.

[0036] Specifically, the front end of the annular mounting disc 1 is provided in a stepped shape. An annular cutting blade 2 is movably sleeved on the outer side of the front end of the annular mounting disc 1. A reinforcing inner ring 3 is fixedly arranged on the inner side of the annular cutting blade 2. The reinforcing inner ring 3 is integrally formed with the annular cutting blade 2 and is used to reinforce the overall strength of the annular cutting blade 2. The inner side wall of the reinforcing inner ring 3 fits the outer surface of the front end of the annular mounting disc 1. Therefore, the annular cutting blade 2 and the reinforcing inner ring 3 can rotate at the front end of the annular mounting disc 1. An annular external tooth 4 is provided on the outer side wall of the reinforcing inner ring 3 and is used to drive the reinforcing inner ring 3 and the annular cutting blade 2 to rotate, so as to realize the cutting of the workpiece to be processed by the annular cutting blade 2. An inner raceway 5 is provided on the inner side wall of the reinforcing inner ring 3;

[0037] Secondly, a guiding groove 6 is opened on the outer surface of the front end of the annular mounting disc 1. A slider 7 is slidably installed in the inner cavity of the guiding groove 6. A limiting ball 8 is movably embedded in one end face of the slider 7. The limiting ball 8 corresponds to the inner raceway 5. When the slider 7 slides in the inner cavity of the guiding groove 6, the limiting ball 8 can be moved into the inner cavity of the inner raceway 5, so as to limit the reinforcing inner ring 3 and prevent the reinforcing inner ring 3 from moving along the length direction of the annular mounting disc 1 and separating from the annular mounting disc 1. And the limiting ball 8 itself can rotate at one end of the slider 7. Therefore, the friction generated between the reinforcing inner ring 3 and one end face of the slider 7 during the rotation of the reinforcing inner ring 3 can be reduced;

[0038] Furthermore, an extrusion block 9 is slidably installed in the middle of the inner cavity of the annular mounting disc 1. The extrusion block 9 is fixedly connected to the movable end of a driving cylinder 10. The driving cylinder 10 is fixedly installed on the back of the annular mounting disc 1. When the driving cylinder 10 works and expands and contracts, it can drive the extrusion block 9 to move, thereby driving the slider 7 to slide in the inner cavity of the guiding groove 6.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, in order to facilitate the installation and disassembly of the annular cutting blade 2 and the reinforcing inner ring 3, the present application also has a communication groove 61 opened at the bottom of the guiding groove 6 and communicating with the middle of the inner cavity of the annular mounting disc 1. A guiding chamfer 15 is provided at one corner of one end of the extrusion block 9. A pressure-receiving block 16 is attached to the outer side wall of the extrusion block 9. The pressure-receiving block 16 is in a "T" shape. The end of the pressure-receiving block 16 penetrates through the communication groove 61 and extends into the inner cavity of the guiding groove 6. The end of the pressure-receiving block 16 is fixedly connected to the slider 7. When the extrusion block 9 slides, the side surface of the extrusion block 9 squeezes the pressure-receiving block 16 and drives the slider 7 to move synchronously, so that the end face of the slider 7 can be abutted against the inner side wall of the reinforcing inner ring 3. When the extrusion block 9 slides reversely, the extrusion block 9 can be separated from the pressure-receiving block 16, and the slider 7 can slide towards the center of the annular mounting disc 1, so as to ensure the separation of the limiting ball 8 from the inner raceway 5, facilitating the removal of the reinforcing inner ring 3 and the annular cutting blade 2 from the front end of the annular mounting disc 1.

[0041] Embodiment 3

[0042] On the basis of Embodiment 2, in order to strengthen the limiting effect on the reinforcing inner ring 3 and the annular cutting blade 2, a plurality of guiding grooves 6 and pressing blocks 16 are provided in the present application, and they are distributed in an annular array on the outer side of the pressing block 9. The cross-section of the pressing block 9 is set as a regular polygon to ensure that a plurality of sliders 7 can evenly abut against multiple positions on the inner wall of the reinforcing inner ring 3, thereby strengthening the limiting effect on the reinforcing inner ring 3 and the annular cutting blade 2.

[0043] Embodiment 4

[0044] On the basis of Embodiment 3, in order to ensure that the driving cylinder 10 can be fixedly installed on the back surface of the annular mounting plate 1, the present application further has a fixing plate 11 fixedly connected to the outer side of the driving cylinder 10. The fixing plate 11 is fixedly connected to the back surface of the annular mounting plate 1 through bolts, so as to ensure that the driving cylinder 10 can be fixed on the back surface of the annular mounting plate 1. The movable end of the driving cylinder 10 is fixedly connected with a connecting ring 12.

[0045] Embodiment 5

[0046] On the basis of Embodiment 4, in order to drive the pressing block 9 to move, the present application further has a baffle 13 fixedly connected to the other end surface of the pressing block 9. A fitting groove 14 is formed by inward depression in the middle of the baffle 13. The connecting ring 12 is located in the inner cavity of the fitting groove 14 and is adapted to it. The connecting ring 12 and the bottom of the fitting groove 14 are fixedly connected by bolts. Therefore, when the driving cylinder 10 expands and contracts, it can drive the pressing block 9 to move synchronously.

[0047] Embodiment 6

[0048] On the basis of Embodiment 5, in order to drive the annular cutting blade 2 to rotate and cut, the present application further has a mounting frame 17 fixedly connected to the outer side wall of the annular mounting plate 1. A driving gear 18 driven by an external motor to rotate is rotatably arranged on one side of the mounting frame 17. The driving gear 18 is in meshing transmission with the annular external teeth 4. Therefore, when the driving gear 18 rotates, it can drive the reinforcing inner ring 3 and the annular cutting blade 2 to rotate, thereby realizing the cutting function.

[0049] Embodiment 7

[0050] On the basis of Embodiment 6, in order to reduce the friction force when the reinforcing inner ring 3 rotates, the present application further has a movable ring 19 movably inlaid on the outer surface of the front end of the annular mounting plate 1. The outer side wall of the movable ring 19 is attached to the inner side wall of the reinforcing inner ring 3. A lubricating grease is provided between the movable ring 19 and the annular mounting plate 1 to reduce the friction force between the inner side wall of the reinforcing inner ring 3 and the outer surface of the annular mounting plate 1.

[0051] Embodiment 8

[0052] On the basis of the seventh embodiment, in order to prevent the extrusion block 9 from being laterally deflected, the present application further has a limiting plate 20 fixedly connected to the inner side wall of the annular mounting disc 1. A guiding through groove 21 is formed through the middle of the limiting plate 20. The extrusion block 9 is movably and penetratingly connected with the guiding through groove 21 and is adapted thereto. The limiting plate 20 and the guiding through groove 21 are used to guide the extrusion block 9 to prevent the extrusion block 9 from being laterally deflected along the radial direction of the annular mounting disc 1.

[0053] Embodiment Nine

[0054] On the basis of the eighth embodiment, in order to prevent the annular mounting disc 1 from colliding with the workpiece to be processed, the present application further has an anti-collision chamfer 22 provided at the front end of the annular mounting disc 1 to improve the convenience of installing the reinforcing inner ring 3. A pressing frame 23 for pressing on the surface of the workpiece to be processed is fixedly connected to the lower side of the outer side wall of the annular mounting disc 1. The pressing frame 23 is in an "L" shape. When the annular cutting blade 2 rotates for cutting, the pressing frame 23 can press on the surface of the workpiece to be processed, thereby preventing collision between the annular mounting disc 1 and the workpiece.

[0055] Embodiment Ten

[0056] On the basis of the ninth embodiment, in order to drive the annular mounting disc 1 to move, the present application further has a connecting frame 24 fixedly connected to the back surface of the annular mounting disc 1. The connecting frame 24 is driven to move by an external power device. Therefore, the annular mounting disc 1 is driven to move by the external power device, thereby changing the cutting position of the annular cutting blade 2 on the workpiece.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention.
