Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 5-10, the clamping tool for the cylindrical grinding wheel provided by the embodiment of the utility model comprises a connecting rod body 20, a spring taper sleeve 30, a fastening screw 40 and a dismounting screw 50;
The connecting rod comprises a connecting rod body 20, a spring taper sleeve 30, a cylindrical grinding wheel 10, a connecting rod sleeve and a connecting rod sleeve, wherein one end of the connecting rod body 20 is a connecting end 202, and the other end of the connecting rod body 20 is a cylindrical connecting part 203;
The spring taper sleeve 30 is provided with a flat bottom 301 at one end and a cylindrical compression joint part 302 at the other end, a plurality of slit grooves 303 are equally spaced on the cylindrical compression joint part 302 of the spring taper sleeve 30, so that a plurality of identical arc-shaped compression joint blocks 304 are formed on the cylindrical compression joint part 302, a conical surface 305 is arranged on one section of outer circle of each arc-shaped compression joint block 304 facing the flat bottom 301, a through hole 306 for allowing a fastening screw 40 to pass through is arranged in the center of the flat bottom 301 of the spring taper sleeve 30, and at least one second threaded hole 307 matched with the dismounting screw 50 is also arranged on the flat bottom 301 of the spring taper sleeve 30.
