DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The rotating disk 5 is fixedly connected to a limiting rod 6 on the outside, and the rotating disk 5 is fixedly connected to a mounting frame 8 on the outside. A mounting block 9 is fixedly connected to the middle of the mounting frame 8. By starting the first motor 4 to rotate the rotating disk 5, the rotating disk 5 rotates with the external fixed mounting frame 8, and the mounting frame 8 rotates with the internal fixed mounting block 9, which plays a role in facilitating the flipping of the workpiece when processing the annular workpiece. A cylinder 10 is fixedly connected to the inside of the mounting block 9, and a protrusion 11 is fixedly connected to the output end of the cylinder 10. The protrusion 11 is A card block 12 is slidably connected, and multiple card blocks 12 are arranged around the interior of the mounting block 9. Telescopic rods 13 are fixedly connected around the interior of the mounting block 9. The tops of multiple telescopic rods 13 are fixedly connected to the outside of multiple card blocks 12. Springs 14 are sleeved on the outside of multiple telescopic rods 13. By arranging the telescopic rods 13 and the springs 14, the auxiliary card blocks 12 are moved. A processing assembly 16 is provided on the upper part of the operating table 2. The processing assembly 16 is used to process the workpiece. An annular groove 7 is provided on the right side of the interior of the operating table 2. The limit rod 6 is slidably connected to the inside of the annular groove 7. A mounting ring 3 is fixedly connected to the right side of the exterior of the operating table 2. The first motor 4 is fixedly connected to the inside of the mounting ring 3. The mounting ring 3 is provided to facilitate fixing the first motor 4. Through holes 15 are provided around the interior of the mounting block 9. Multiple card blocks 12 are slidably connected to the inside of multiple through holes 15. The provision of through holes 15 plays a guiding role.
[0027] Specifically, when fixing the annular workpiece in the machining center, first, the annular workpiece is placed outside the four clamping blocks 12, then the cylinder 10 is started, and a protrusion 11 is fixed to the output end of the cylinder 10. After starting, the protrusion 11 starts to move, pushing the clamping blocks 12 connected to the outside to slide. As the protrusion 11 moves, the four clamping blocks 12 slide toward the outside of the mounting block 9. When the four clamping blocks 12 move, they gradually apply pressure to the four telescopic rods 13 located at the rear side thereof. The four telescopic rods 13 begin to contract after being squeezed, and drive the outside to move. The four springs 14 arranged at the top are deformed. When the clamping block 12 continues to move outward until it contacts the inner periphery of the annular workpiece, the fixation of the workpiece is completed. At this time, the clamping block 12 fits tightly with the annular workpiece to form a uniform clamping force, and there is no need for the operator to manually tighten the bolts and other tedious operations. This not only reduces the complexity of manual operation and ensures that the clamping force remains consistent each time, thereby avoiding the uneven clamping force in traditional manual operation, ensuring that the annular workpiece remains stable and accurate during the processing, thereby improving the final processing quality.

Fixed rods 25 are fixedly connected on both sides of the interior of the operating table 2, and the two guide blocks 24 are slidably connected to the outside of the two fixed rods 25. The setting of the fixed rods 25 plays a role in guiding the guide blocks 24. A drawer 27 is slidably connected to the front side of the interior of the operating table 2, and a handle is fixedly connected to the outside of the drawer 27. The setting of the drawer 27 facilitates the collection of debris on the upper part of the operating table 2 for centralized processing.
[0029] Specifically, after the workpiece processing is completed, the third motor 19 is started. After the third motor 19 is started, it drives the turntable 20 fixed at its output end to rotate. As the turntable 20 rotates, the positioning rod 21 located at the upper part also rotates accordingly. The rotation of the positioning rod 21 further drives the connecting rod 22 connected to its external rotation to move. Through this rotation, the connecting rod 22 drives the fixed block 23 connected to the other end to move. When the fixed block 23 moves, it cooperates with the two guide blocks 24 to achieve reciprocating movement outside the two fixed rods 25. While the fixed block 23 moves, it drives the cleaning brush 26 fixed at the lower part to move synchronously. During this reciprocating movement, the cleaning brush 26 sweeps back and forth along the upper surface of the support platform, gradually pushing the processing debris fallen on the upper part of the operating table 2 to one side of the platform until all the debris is pushed into the drawer 27 provided under the platform, thereby facilitating the cleaning of the debris fallen on the upper part of the support platform and avoiding the accumulation of debris on the platform.
[0030] Reference Figure 1 、 Figure 2 and Figure 3 The processing assembly 16 includes an electric push rod 1601, which is fixedly connected to the upper right side of the operating table 2. The output end of the electric push rod 1601 is fixedly connected to a horizontal plate 1602, and the outside of the horizontal plate 1602 is fixedly connected to a mounting plate 1603. A second motor 1604 is provided on the lower left side of the mounting plate 1603, and a cutting knife 1605 is fixedly connected to the output end of the second motor 1604. Guide rods 17 are fixedly connected on both sides of the inside of the operating table 2. The horizontal plate 1602 is slidably connected to the outside of the two guide rods 17. The two guide rods 17 are provided to guide the horizontal plate 1602. The left side of the outside of the mounting plate 1603 is fixedly connected to a support frame 18. The second motor 1604 is fixedly connected to the inside of the support frame 18. The support frame 18 is provided to fix the second motor 1604.
[0031] Specifically, when processing an annular workpiece, the electric push rod 1601 is started, and the electric push rod 1601 moves the horizontal plate 1602 fixed at the output end outside the two guide rods 17. When the horizontal plate 1602 moves to the appropriate position, the second motor 1604 is started, and the second motor 1604 rotates the cutting knife 1605 fixed at the output end. The cutting processing of the annular workpiece can be completed by the rotation of the cutting knife 1605.
[0032] Working principle: When it is necessary to fix the annular workpiece, first, place the annular workpiece on the outside of the four clamping blocks 12. At this time, start the cylinder 10, and the cylinder 10 moves with the protrusion 11 fixed on the output end. The movement of the protrusion 11 pushes the sliding block 12 connected to the outside to move toward the outside of the mounting block 9. The four clamping blocks 12 move to squeeze the four telescopic rods 13 fixed on the rear side of the outside. The four telescopic rods 13 shrink and cause the four springs 14 set on the outside to deform. When the four clamping blocks 12 are in contact with the inner periphery of the annular workpiece, the workpiece can be fixed, which makes it easy to fix the workpiece. When fixing the workpiece, there is no need for the operator to manually tighten the bolts to fix it, ensuring that the clamping force can be kept consistent each time, avoiding uneven clamping force or positioning error caused by manual operation, and improving the processing quality of the workpiece. After the workpiece is processed, the third motor 19 is started, and the third motor 19 drives the turntable 20 fixed at the output end to rotate. The rotation of the turntable 20 drives the positioning rod 21 fixed on the upper part to rotate. The rotation of the positioning rod 21 drives the connecting rod 22 connected to the external rotation to move. The connecting rod 22 moves and drives the fixed block 23 connected to the other end to move back and forth on the outside of the two fixed rods 25 through the cooperation of the two guide blocks 24. When the fixed block 23 moves, it drives the cleaning brush 26 fixed at the lower part to move synchronously. The movement of the cleaning brush 26 can push the debris fallen on the upper part of the operating table 2 to the inside of the drawer 27, so that after the workpiece processing is completed in the machining center, it is convenient to clean the debris fallen on the upper part of the support platform, avoid affecting the subsequent workpiece processing due to the accumulation of debris, and improve the processing efficiency of the workpiece.
