Claims

[Scope of utility model registration request]

A boss portion 1 is attached to a tapered shaft 7 provided at one end of a grindstone drive shaft 1 rotated by a drive means.
5 and a flange portion 18 having a larger diameter than this boss portion 15; and this inner flange 1.
A grindstone flange 2 comprising an outer flange 23 that is fitted onto the outer periphery of the boss portion of No. 4 and fixes the grindstone G fitted on the outer periphery of the boss portion together with the flange portion 18.
A front plate 28 having a rectangular presser plate insertion hole 29 and fixed to the outer end surface of the boss portion, which is a mechanism for attaching and detaching a grindstone flange to and from the grindstone drive shaft for attaching and detaching the tapered hole 19 of the boss portion of No. 7; A grindstone flange holding plate 32 is loosely fitted on the head side of the shaft, and a grindstone flange punching plate 34 having a size that cannot be inserted into the holding plate insertion hole 29 is fixed on the threaded side so that the threaded part is connected to the tapered shaft. When the grindstone flange 27 is fitted to the tapered shaft 7, the grindstone flange holding plate 32 is located outside the front plate 28. Together with the grinding wheel flange punching plate 3
4 is located inside the front plate 28, and the grindstone flange holding plate 32 can be inserted into the holding plate insertion hole 29 when aligned, but cannot be inserted into the holding plate insertion hole 29 when the position is shifted. A mechanism for attaching and detaching the grinding wheel flange to the grinding wheel drive shaft.
