DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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] Example 1:

[0022] See also Figure 1 The utility model provides a technical solution: a carbon felt insulation cylinder outer cylindrical grinding processing device, including a base 1, with supporting outer columns 2 installed at the four corners of the top of the base 1, and supporting inner columns 3 inserted into the inner side of the supporting outer columns 2. A processing table 4 is installed on the top of the four supporting inner columns 3. Positioning screw holes 16 are equidistantly provided on the surface of the supporting inner columns 3, and positioning bolts 17 are inserted into the surface of the supporting outer columns 2. The positioning bolts 17 are threadedly connected to the positioning screw holes 16.

[0023] In this embodiment, please refer to Figure 1 Two supporting plates 5 are provided on the top of the processing table 4. The inner sides of the two supporting plates 5 are installed with chucks 6 through bearings. A carbon felt insulation cylinder 7 is clamped between the two chucks 6. The chuck 6 is a common existing technology (see publication number CN218776326U). The carbon felt insulation cylinder 7 to be ground on the outer circle can be clamped and fixed by the chuck 6.

[0024] In this embodiment, please refer to Figure 1 and Figure 2The two movable blocks 81 are respectively installed at the bottom of the two supporting plates 5, and the top of the processing table 4 is provided with two limiting slide grooves 82 adapted to the movable blocks 81.

Connecting rods 85 are hinged between the top sides of the lifting plate 84 and the bottom of the two movable blocks 81. When it is necessary to clamp and fix the carbon felt insulation tube 7 of different lengths, the lifting cylinder 83 is started to drive the lifting plate 84 to move up and down. With the cooperation of the connecting rod 85, the movable blocks 81 in the two limiting slide grooves 82 drive the two supporting plates 5 to move away from or close to each other, thereby making the distance between the two chucks 6 adapt to the length of the carbon felt insulation tube 7, thereby improving the practicality of the device.

[0025] In this embodiment, please refer to Figure 1 , fixed frames 9 are installed on both sides of the top of the processing table 4, and a mounting seat 10 is provided between the two fixed frames 9.
