[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] like Figures 5-10 As shown in the figure, a clamping fixture for a cylindrical grinding wheel proposed in this embodiment of the present invention includes: a connecting rod body 20, a spring cone sleeve 30, a fastening screw 40, and a disassembly screw 50;

[0024] One end of the connecting rod body 20 is a connecting end 202, and the other end is a cylindrical connecting part 203; the bottom center of the cylindrical connecting part 203 of the connecting rod body 20 has a first threaded hole adapted to the fastening screw 40; the connecting end 202 of the connecting rod body 20 is used to connect the grinding machine, and the cylindrical connecting part 203 of the connecting rod body 20 is used to connect the spring cone sleeve 30 and the cylindrical grinding wheel 10;

[0025] One end of the spring cone sleeve 30 is a flat bottom 301, and the other end is a cylindrical pressing part 302. Multiple slots 303 are evenly spaced in the cylindrical pressing part 302 of the spring cone sleeve 30, thereby forming multiple identical arc-shaped pressing blocks 304 in the cylindrical pressing part 302. A conical surface 305 is provided on the outer circle of each arc-shaped pressing block 304 facing the flat bottom 301. A through hole 306 for fastening screw 40 to pass through is provided at the center of the flat bottom 301 of the spring cone sleeve 30. At least one second threaded hole 307 adapted to the disassembly screw 50 is also provided in the flat bottom 301 of the spring cone sleeve 30.

[0026] like Figure 10 As shown, when clamping the cylindrical grinding wheel 10, first, the spring cone sleeve 30 is placed into the cylindrical connecting part 203 of the connecting rod body 20, with the cylindrical pressing part 302 of the spring cone sleeve 30 facing outwards; then, the cylindrical grinding wheel 10 is placed into the cylindrical pressing part 302 of the spring cone sleeve 30, with the front end face, i.e., the grinding end face, of the cylindrical grinding wheel 10 facing outwards; then, the fastening screw 40 is placed into the cylindrical grinding wheel 10, and the fastening screw 40 passes through the through hole 306 at the center of the flat bottom 301 of the spring cone sleeve 30 and connects to the first threaded hole at the center of the bottom of the cylindrical connecting part 203 of the connecting rod body 20; tighten the fastening screw 40, at which point the inner wall of the cylindrical connecting part 203 of the connecting rod body 20 is pressed against the conical surface 305 on the outer circle of the spring cone sleeve 30, causing each arc-shaped pressing block 304 of the cylindrical pressing part 302 to grip the cylindrical grinding wheel 10; the clamping is completed. The clamping fixture proposed in this embodiment of the utility model can ensure the concentricity of the cylindrical grinding wheel after clamping and has good axial stability; the cylindrical grinding wheel 10 is very stable during operation, avoiding product failure and environmental pollution caused by vibration and noise during the grinding process.
