[0040] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] First embodiment:

[0042] like Figure 1-7As shown, a clasp processing device includes: a base 1, a turntable 2, a first grinding mechanism 3, a second grinding mechanism 4, a third grinding mechanism 5, and clamping mechanisms. The turntable 2 is connected to the base 1 via a shaft and can be rotated by a motor and gears. The first grinding mechanism 3, the second grinding mechanism 4, and the third grinding mechanism 5 are arranged sequentially around the turntable 2. The first grinding mechanism 3 is used to grind the end face of the clasp, the second grinding mechanism 4 is used to grind the inner wall of the clasp, and the third grinding mechanism 5 is used to grind the outer wall of the clasp. Four clamping mechanisms are evenly arranged around the turntable 2. After processing one step, rotating the turntable 2 moves to the next grinding step, achieving continuous processing.

[0043] Specifically, each clamping mechanism includes a machining groove 61, a positioning post 62, a clamping rod 63, a first driving member 64, a clamping rod 63 driving assembly, a mounting plate 65, a sliding rod 66, a first elastic member 67, a locking block 68, a driving assembly for the positioning post 62, and a second driving member 69. The machining groove 61 is formed on the turntable 2; the positioning post 62 is located in the machining groove 61 and can be fitted with a retaining ring; the machining groove 61 has a circular hole for the positioning post 62 to move up and down; the clamping rods 63 are symmetrically arranged in the machining groove 61, and the bottom of the machining groove 61 has a sliding groove for clamping movement; the first driving member 64 is a servo motor, and its output shaft is connected to the clamping rod 63; the second driving member 69 is an electric push rod, which is located in the machining groove 61. 1. On the side wall; mounting plate 65 is fixed to the output end of the second drive member 69; slide rod 66 passes through mounting plate 65 and can slide relative to mounting plate 65; the first elastic member 67 is a spring, which is sleeved on slide rod 66, and one end is fixed to mounting plate 65, and the other end is fixed to clamp block 68; clamp block 68 is fixed to the end of slide rod 66, and clamp block 68 can be inserted into the opening of the retaining ring to prevent the retaining ring from deforming when clamping the retaining ring; positioning post 62 drives the top post 621 and the seventh drive member 622. The top post 621 is fixed to the bottom end of positioning post 62. The diameter of top post 621 is larger than the diameter of positioning post 62 and smaller than the outer diameter of retaining ring; the seventh drive member 622 is an electric push rod. When processing the retaining ring, first The robotic arm places the retaining ring on the bottom of the processing groove 61 and fits it onto the positioning post 62. Then, the chuck is rotated 90 degrees, moving the retaining ring to the first grinding mechanism 3. The clamping rod 63 is then moved by the clamping rod drive assembly, bringing its end into contact with the outer wall of the retaining ring. The second drive unit 69 is activated, pushing the retaining block 68 into contact with the outer wall of the retaining ring. The first drive unit 64 is then activated, rotating the clamping rod 63, which in turn rotates the retaining ring relative to the positioning post 62. When the opening of the retaining ring aligns with the retaining block 68, the first drive unit 64 is closed, and the first elastic element 67 pushes the retaining block 68 into the opening. The clamping rod 63 is then moved again by the clamping rod drive assembly to clamp the retaining ring. Finally, the first... Grinding mechanism 3 grinds the end face of the retaining ring. After grinding, the turntable 2 rotates 90 degrees, and the positioning post 62 is moved down by the seventh drive member 622, causing the positioning post 62 to disengage from the inner wall of the retaining ring. Then, the second grinding mechanism 4 grinds the inner wall of the retaining ring. After grinding, the turntable 2 rotates 90 degrees again, and the positioning post 62 is inserted into part of the retaining ring by the seventh drive member 622. Then, the clamping rod 63 and the clamping block 68 are reset. Next, the positioning post 62 is moved up again, and the top post 621 pushes the retaining ring up. Then, the outer wall of the retaining ring is ground by the third grinding mechanism 5. After grinding, the retaining ring is removed. The turntable 2 rotates to transport the retaining ring to the three grinding mechanisms for grinding the end face, inner wall, and outer wall. The positioning post 62 in the clamping mechanism is used for the initial positioning of the retaining ring. The clamping rod 63 rotates and moves by the drive member, and cooperates with the clamping block 68 to insert into the opening of the retaining ring to achieve multi-point clamping.The design of the elastic element and slide bar 66 ensures that the clamping block 68 adapts to the opening position of the retaining ring, and the positioning post 62 drives the assembly to adjust its height to adapt to different processing stages. Multi-station continuous processing improves efficiency; the multi-point fixing of the clamping mechanism avoids the deformation of the retaining ring and improves processing accuracy; the adaptive design of the elastic element and slide bar 66 reduces the need for manual adjustment.

[0044] Specifically, the clamping rod 63 drive assembly includes a fixed base 631, a connecting rod 632, a second elastic element 633, a fixed plate 634, a sleeve 635, and a third drive element 636. The fixed base 631 is fixed to the outer wall of the first drive element 64; the connecting rod 632 is fixed to the fixed base 631; the second elastic element 633 is a spring, one end of which is fixed to the connecting rod 632, and the other end is fixed inside the sleeve 635; the sleeve 635 is fixed to the fixed plate 634, and the connecting rod 632 can slide relative to the inner wall of the sleeve 635; the third drive element 636 is an electric push rod, and its output end is fixed to the fixed plate 634; the elastic buffer prevents excessive clamping force from causing deformation of the retaining ring.

[0045] As a preferred embodiment, the clamping rod 63 is provided with a plurality of anti-slip protrusions 637 evenly, which facilitates the rotation of the retaining ring and prevents the retaining ring from sliding during processing; pressure sensors are provided on both sides of the clamping block 68, and the pressure sensors are communicatively connected to the controller of the first driving component 64. When the clamping block 68 is engaged in the opening of the retaining ring, the pressure sensors will send a signal to the controller of the first driving component 64 to shut down the first driving component 64.

[0046] Specifically, the first polishing mechanism 3 includes a polishing plate 31, a fourth driving component 32, a first robotic arm 33 for controlling the up-and-down and horizontal movement of the polishing plate 31, and a material-turning assembly. The fourth driving component 32 is a servo motor, which is fixed on the first robotic arm 33. The first robotic arm 33 can drive the fourth driving component 32 to move up-and-down and horizontally. The polishing plate 31 is connected to the output shaft of the fourth driving component 32 via a shaft. The material-turning assembly includes a fixing ring 34, a rotating shaft 35, a fifth driving component 36, a clamping ring 37, a connecting frame 38, and a sixth driving component 39. The sixth driving component 39 is an electric push rod. The connecting frame 38 is fixed on the output end of the sixth driving component 39. The fixing ring 34 is fixed on the connecting frame 38. The rotating shaft 35 is rotatably connected to the fixing ring 34. The fifth driving component 36 is a servo motor, and its output shaft is connected to the rotating shaft 35. Ring 37 is fixed to the end of rotating shaft 35, and an electromagnet is fixed to its bottom surface. The first robotic arm 33 can bring the polishing plate 31 into contact with the end face of the retaining ring. Then, the fourth driving member 32 drives the polishing plate 31 to rotate and polish the end of the retaining ring. After polishing, the first robotic arm 33 removes the polishing plate 31 from the processing groove 61 and moves the polishing plate 31 away from the top of the processing groove 61. Then, the clamping plate is moved down so that the electromagnet on the bottom surface of the clamping ring 37 contacts the retaining ring. The electromagnet is activated and the clamping block 68 and clamping rod 63 are reset. Then, the clamping ring 37 is moved up and the retaining ring is rotated 180 degrees by the fifth driving member 36. The clamping ring 37 is moved down and placed into the processing groove 61. The retaining ring is then fixed by the clamping block 68 and clamping rod 63. Finally, the end face of the retaining ring is polished. The double-sided polishing is completed in one integrated process, reducing the process changeover time.

[0047] Specifically, the second polishing mechanism 4 includes a polishing frame 41, a pressure rod 42, a first ball bearing 43, a polishing rod 44, and a second robotic arm 45. The polishing frame 41 is connected to the second robotic arm 45; the pressure rod 42 is fixed on the polishing frame 41; the first ball bearing 43 is rotatably connected to the end of the pressure rod 42; the polishing rod 44 is rotatably connected to the polishing frame 41, and the polishing frame 41 is equipped with a motor that drives the polishing rod 44 to rotate; the second robotic arm 45 can drive the polishing rod 44 to move up and down and along the inner wall of the retaining ring. When the retaining ring moves to the second grinding mechanism 4, the positioning post 62 is moved down by the seventh driving member 622, so that the positioning post 62 is disengaged from the inner wall of the retaining ring. Then the grinding frame 41 is moved down, so that the first ball 43 presses on the top of the retaining ring, and the grinding rod 44 contacts the inner wall of the retaining ring. Then the grinding rod 44 is rotated to grind the inner wall of the retaining ring, and the second mechanical arm 45 drives the grinding rod 44 to move along the inner wall of the retaining ring. The third grinding mechanism 5 is the same as the second grinding mechanism 4, and the specific structure will not be described in detail.

[0048] Second embodiment:

[0049] like Figure 8As shown, this embodiment differs from the first embodiment in that the positioning post 62 is provided with an adjustment assembly, which includes a mounting cavity 71, a support rod 72, a top plate 73, and a control component. The mounting cavity 71 is opened inside the top post 621; the support rod 72 is evenly arranged around the positioning post 62, with one end extending into the mounting cavity 71 and being slidable relative to the positioning post 62; the top plate 73 is fixed to the end of the support rod 72; the control component includes a limiting plate 74, a third elastic element 75, a second ball bearing 76, a screw 77, and a control block 78.

The rod 77 is screwed onto the positioning post 62; the control block 78 is evenly fixed on the screw 77, the control block 78 has an arc-shaped curved surface 781, and the control block 78 is correspondingly set with the support rod 72; the second ball 76 is rotatably connected to the end of the control rod; the third elastic element 75 is a spring, which is sleeved on the support rod 72, and one end of the third elastic element 75 is fixed to the limiting plate 74, and the other end is fixed to the inner wall of the mounting cavity 71. By rotating the screw 77, the support rod 72 can be pushed to move, thereby adjusting the distance between the top plate 73 and the positioning post 62, which is convenient for adapting to different sizes of retaining rings.
