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.

[0021] The embodiment of the present application discloses a special machine for inner circle ceramics.

[0022] Example

[0023] according to Figures 1 to 3 As shown, the inner circle ceramic special machine includes a mounting base 1, a fixed cylinder 3, a rotary cylinder 2 and a spring chuck 4. The left and right sides of the mounting base 1 are respectively rotatably connected with the rotary cylinder 2 and the fixed cylinder 3. The interior of the fixed cylinder 3 is slidably connected with the spring chuck 4. The end of the spring chuck 4 is located outside the fixed cylinder 3. The conical surface 6 of the spring chuck 4 is elastically squeezed with the end of the fixed cylinder 3. The end of the piston rod of the rotary cylinder 2 extends into the interior of the mounting base 1 and is fixedly connected with the pull rod 5 of the spring chuck 4.

[0024] A cavity is provided inside the mounting seat 1, and a stroke height step 9 is fixedly connected to one side of the mounting seat 1. The end of the stroke height step 9 is rotatably connected to the fixed cylinder 3, and the interior of the fixed cylinder 3 is slidably connected to the spring chuck 4. The rotary cylinder 2 is concentrically arranged with the cavity, the stroke height step 9, the fixed cylinder 3, and the spring chuck 4. The end of the piston rod of the rotary cylinder 2 passes through the cavity, the stroke height step 9 and is fixedly connected to the pull rod 5 of the spring chuck 4 in sequence. The conical surface 6 of the spring chuck 4 is located inside the fixed cylinder 3, and the outer diameter of the spring chuck 4 matches the inner diameter of the fixed cylinder 3. The conical surface 6 of the spring chuck 4 contacts and slides with the fixed cylinder 3. The piston rod of the rotary cylinder 2 drives the conical surface 6 of the spring chuck 4 to be elastically squeezed with the fixed cylinder 3 through telescoping, thereby realizing the opening and gathering of the spring chuck 4.

[0025] The rotary cylinder 2 in the present invention is an RQ-130B hollow rotary cylinder. The end of the rotary cylinder 2 is rotatably connected to a cooling device 7. A rotary seal is provided between the rotary cylinder 2 and the cooling device 7. The rotary cylinder 2 can rotate relative to the cooling device 7. The rotary seal belongs to the prior art. The rotary seal ensures the sealing of the rotary cylinder 2 when it rotates relative to the cooling device 7. A cooling pipe 8 is installed at the end of the cooling device 7. The cooling device 7 and the cooling pipe 8 provide coolant to the center of the spring chuck 4, so that the spring chuck 4 clamps the ceramic product and rotates at high speed, which can be quickly cooled. Ceramic processing coolant is added to the coolant. The cooling pipe 8 is made of corrosion-resistant polyaryletherketone material, and the fixed cylinder 3 is made of high-hardness quenching material.

[0026] The rotation of the rotary cylinder 2 and the extension and retraction of the piston rod belong to the existing technology and will not be described in detail here. The spring chuck 4 belongs to the existing technology and will not be described in detail here. The cooling device 7 provides coolant and belongs to the existing technology and will not be described in detail here.

[0027] The spring chuck 4 includes four sub-chucks, which are cylindrical as a whole. The four sub-chucks enable the spring chuck 4 to maintain a uniform clamping force when clamping ceramic products, and make the ceramic products less likely to break during the inner circle rotation processing. The design of the stroke height step 9 enables longer ceramic products to be processed. The stroke height step 9 extends the length of the fixed cylinder 3. The stroke height step 9 cooperates with the fixed cylinder 3, so that the spring chuck 4 can accommodate longer-sized ceramic products when clamping ceramic products, and the stroke height step 9 can also improve the supporting strength of the fixed cylinder 3.

[0028] Working principle:

[0029] In the initial state, the piston rod of the rotary cylinder 2 is in a retracted state. The rotary cylinder 2 is started, and the piston rod of the rotary cylinder 2 extends. While extending, the piston rod pushes the spring chuck 4 in a direction away from the fixed cylinder 3. The piston rod pushes the conical surface 6 of the spring chuck 4 out of the fixed cylinder 3. The four sub-chucks are in an open state. The ceramic product to be clamped is placed inside the spring chuck 4. At this time, the piston rod of the rotary cylinder 2 is retracted. The piston rod drives the spring chuck 4 to move in the direction of the fixed cylinder 3 through the pull rod 5. The conical surface 6 of the spring chuck 4 contacts and squeezes the inner wall of the fixed cylinder 3, thereby achieving the purpose of clamping and fixing the ceramic product. When the ceramic product needs to be rotated, the rotary cylinder 2 and the fixed cylinder 3 rotate synchronously with the rotation of the ceramic product to improve the stability of the clamping.

[0030] When the spring chuck 4 needs to be cooled, the coolant is transported to the cooling device 7 through the cooling pipe 8. The coolant passes through the cooling device 7, the center of the rotary cylinder 2, the cavity of the mounting seat 1, the stroke height step 9, the fixed cylinder 3, and finally reaches the spring chuck 4 to cool the spring chuck 4. During the inner circle machining process and the cooling process of the ceramic product, the mounting seat 1, the stroke height step 9, the cooling pipe 8, and the cooling device 7 remain stationary, and the rotary cylinder 2, the fixed cylinder 3, and the spring chuck 4 rotate.
