[0002] With the development of emerging industries such as electronic communication chips, new energy, aerospace, marine bioengineering, and medical treatment, higher requirements have been put forward for their materials. New ceramic material structural parts have excellent functions in terms of high hardness, scratch resistance, wear resistance, corrosion resistance, high temperature resistance, thermal shock resistance, and antibacterial properties. They can be used in the manufacture of engine blades, ceramic bearings, ceramic tools, ceramic abrasives, artificial joints, dental restorations, etc., thereby meeting the needs of the development of modern science and technology and playing an increasingly important role in these industries.

[0003] However, due to the tight molecular structure and lack of elasticity of ceramic materials, sharp corners are prone to edge collapse and chipping during processing, which can easily lead to the appearance of waste products. Therefore, sharp corners in each process of ceramic structural parts processing must be blunted in time.

[0004] In the chamfering process of ceramic sleeve parts, the ceramic sleeve parts rely solely on the triangular chuck for positioning, which leads to the phenomenon of edge collapse and chipping when the tool contacts the ceramic sleeve parts, which easily leads to the appearance of waste. In the existing ceramic structural parts processing industry, the chamfering of sharp angles is almost a manual operation, and the chamfering of sharp angles of ceramic structural parts has become one of the main reasons affecting the processing efficiency.

[0027] See also Figure 1-Figure 3 As shown, the utility model provides a fast chamfering clamping device for ceramic sleeve parts, including a three-jaw chuck 1, on which three grippers 2 for clamping a ceramic sleeve component 8 are provided. When the ceramic sleeve component 8 is placed on the three-jaw chuck 1, two or three grippers 2 are used to clamp the ceramic sleeve component 8, and the grippers 2 are used to realize the center positioning of the ceramic sleeve component 8;

[0028] A positioning plate 3 is slidably connected to the three-jaw chuck 1, and a locking member 5 for fastening is provided between the positioning plate 3 and the three-jaw chuck 1. After the locking member 5 is released from locking the positioning plate 3, the positioning plate 3 can be slid, and after sliding to a suitable position, the locking member 5 can be used to lock and fix the positioning plate 3;

[0029] A V-shaped frame 7 for supporting the ceramic sleeve component 8 is provided on the positioning plate 3. In a preferred embodiment, the V-shaped frame 7 is integrally formed with the positioning plate 3, and the upper surface of the V-shaped frame 7 is in a "v"-shaped structure. The ceramic sleeve component 8 is supported by the V-shaped frame 7. A door frame 12 is connected to the positioning plate 3 or the V-shaped frame 7. A pressing component 10 for pressing the ceramic sleeve component 8 is slidably connected inside the door frame 12. An adjusting member 11 for driving the pressing component 10 to adjust its height is provided on the door frame 12.

[0030] When the device is in use, the ceramic sleeve component 8 is passed through the space between the pressing component 10 and the V-frame 7, and the ceramic sleeve component 8 is clamped by the grasping clamp 2, so that the ceramic sleeve component 8 can be fixed on the surface of the three-jaw chuck 1 to realize the axial positioning of the ceramic sleeve component 8, and the locking of the positioning plate 3 by the locking member 5 is released, so that the positioning plate 3 slides on the surface of the three-jaw chuck 1 until the side of the V-frame 7 contacts the outer wall of the ceramic sleeve component 8, and the positioning plate 3 is locked by the locking member 5, and the position of the pressing component 10 is adjusted by the adjusting member 11 so that the pressing component 10 slides on the inner side of the gate frame 12, and the ceramic sleeve component 8 is pressed by the pressing component 10 to realize the fixing of the ceramic sleeve component 8. After the fixing is completed, the end of the ceramic sleeve component 8 passes through the V-frame 7, and the end face of the ceramic sleeve component 8 is chamfered by machinery, so that the ceramic sleeve component 8 can be protected as a whole;

[0031] In subsequent processing, when the diameter of the ceramic sleeve component 8 does not change, it is only necessary to increase the distance between the clamping component 10 and the ceramic sleeve component 8 to conveniently install the ceramic sleeve component 8 on the three-jaw chuck 1, and lock the ceramic sleeve component 8 through the clamp 2. It is only necessary to adjust the height of the clamping component 10 to clamp and fix the ceramic sleeve component 8. The operation is simple and convenient, suitable for small-batch continuous processing of multiple ceramic sleeve components 8 of the same size, and greatly improves the processing efficiency of the ceramic sleeve components 8. The positioning plate 3 and the V-frame 7 of the device can be slidably adjusted, and the device can adapt to the processing of ceramic sleeve components 8 of various sizes, and the processing is more flexible.

[0032] The second embodiment is different from the first embodiment in that:

[0033] The surface of the three-jaw chuck 1 is provided with a guide column 6, and the surface of the positioning plate 3 is provided with a slide groove that slidably cooperates with the guide column 6. The sliding cooperation between the positioning plate 3 and the guide column 6 can guide the positioning plate 3 so that the positioning plate 3 can slide smoothly. In the structure of the locking member 5, the locking member 5 is a bolt or nut structure, and the locking member 5 is threadedly connected to the guide column 6. After tightening the locking member 5, the locking member 5 can be used to press the positioning plate 3 to achieve the fixation of the guide column 6. Further, the locking member 5 is provided with a reinforcing gasket 4 on one side close to the positioning plate 3 to improve the pressing and fixing effect of the positioning plate 3;

[0034] In different embodiments, the locking piece 5 is threadedly connected to the three-jaw chuck 1, and a guide groove is provided on the surface of the positioning plate 3. The locking piece 5 is located on the inner side of the guide groove. The locking piece 5 is installed on the three-jaw chuck 1. After tightening the locking piece 5, the positioning plate 3 can be pressed. At this time, the guide column 6 and the positioning plate 3 only have a guiding function, but not a pressing function. After loosening the locking piece 5, the positioning plate 3 can be released, so that the guide column 6 can be used to guide the positioning plate 3 to achieve the movement of the positioning plate 3.

[0035] The third embodiment is different from the first embodiment in that:

[0036] The pressing component 10 is in the shape of a letter "I" or an inverted isosceles trapezoid or a "T" shape. Furthermore, the pressing component 10 is detachably connected to the adjusting member 11, and the pressing component 10 can be disassembled, so that pressing components 10 of different structures can be selected to press the ceramic sleeve component 8;

[0037] When the diameter of the ceramic sleeve component 8 is large, see Figure 1 As shown, when the ceramic sleeve component 8 is located on the V-shaped frame 7, its top surface is higher than the top of the V-shaped frame 7, and an "I" structure can be selected to use the "I"-shaped pressing component 10 to press the ceramic sleeve component 8;

[0038] When the diameter of the ceramic sleeve component 8 is large, see Figure 2 As shown, when the ceramic sleeve component 8 is located on the V-shaped frame 7, its top surface is lower than the top of the V-shaped frame 7, and an inverted isosceles trapezoid or a "T"-shaped structure can be selected. The two sides of the isosceles trapezoid can extend into the interior of the V-shaped frame 7, and the ceramic sleeve component 8 can be pressed by the small end surface at the bottom of the isosceles trapezoid and the small end at the bottom of the "T"-shaped structure to achieve the pressing of the ceramic sleeve component 8. The pressing components 10 with different structures can be selected according to the ceramic sleeve components 8 with different diameters;

[0039] When the clamping component 10 is connected to the adjusting component 11, the adjusting component 11 is threadedly matched with the door frame 12, and the bottom end of the adjusting component 11 is rotatably connected to the clamping component 10. When the adjusting component 11 is rotated, the adjusting component 11 is threadedly matched with the door frame 12, and the clamping component 10 slides with the inner wall of the door frame 12 to guide the clamping component 10 so that the clamping component 10 can move up and down smoothly. In the rotational connection between the adjusting component 11 and the clamping component 10, a rotating block is rotatably connected to the bottom of the adjusting component 11, and an opening corresponding to the rotating block is provided on the upper surface of the clamping component 10. The rotating block is inserted into the opening, and the clamping component 10 and the rotating block can be connected by bolts to realize the connection between the clamping component 10 and the adjusting component 11.

[0040] Furthermore, the clamping component 10 is provided with an extension rod 14 corresponding to the adjusting component 11. When the ceramic sleeve component 8 with a smaller diameter is clamped, the distance between the top of the portal frame 12 and the ceramic sleeve component 8 is larger. The extension rod 14 can be connected to the clamping component 10, and the top of the extension rod 14 is rotatably connected to the adjusting component 11, thereby assisting the clamping component 10 in clamping the ceramic sleeve component 8. An adjusting component 11 with a longer length can also be selected to connect the portal frame 12 and the clamping component 10 for operation.

[0041] The fourth embodiment is different from the third embodiment in that:

[0042] The door frame 12 is provided with a sliding groove 13, and the two ends of the pressing component 10 are provided with protrusions that slide with the sliding groove 13, and the pressing component 10 is guided by the sliding cooperation between the sliding groove 13 and the protrusions;

[0043] Specifically, when the thickness of the clamping component 10 is greater than the thickness of the protrusion, the sliding groove 13 penetrates to the bottom surface of the portal frame 12. When the clamping component 10 is replaced, the portal frame 12 is disassembled from the V-frame 7 or the three-jaw chuck 1, and the connection between the adjusting member 11 and the clamping component 10 is released. By sliding the protrusion and the sliding groove 13, the clamping component 10 can slide out of the bottom sliding groove 13 of the portal frame 12, thereby realizing the disassembly and replacement operation of the clamping component 10;

[0044] When the thickness of the clamping component 10 is less than or equal to the thickness of the protrusion, the sliding groove 13 penetrates to the top or bottom surface of the door frame 12. When the clamping component 10 is disassembled and replaced, the three-jaw chuck 1 can be used to drive the clamping component 10 to slide upward, so that the clamping component 10 can be guided out from the top of the sliding groove 13. The clamping component 10 can be replaced without disassembling the door frame 12, which is more convenient. Figure 3 shown.

[0045] A convex part 9 is provided at the bottom opening of the door frame 12 , and a slide groove slidably matched with the convex part 9 is provided on the V-shaped frame 7 . The slide groove is arranged on both sides of the V-shaped frame 7 and extends horizontally outside the V-shaped frame 7 .
