Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses just, structure is torn open to numerical control cylindrical grinder's emery wheel. Referring to fig. 1-4, a structure is just torn open to numerical control cylindrical grinder's emery wheel, including drive shaft 1, emery wheel body 2 and flange 3, the outside fixed mounting of drive shaft 1 has emery wheel body 2, flange 3 is installed to one side of emery wheel body 2, one side fixed mounting of flange 3 has spacing bolt 4, the one end of drive shaft 1 is pegged graft and is had spacing dish 5, the inboard of spacing dish 5 is run through and has been seted up slot 6, and the activity of spacing bolt 4 runs through the inner chamber of slot 6, the fixed recess 7 of having seted up of one end of spacing bolt 4, spring 8 is installed to the inner chamber of recess 7, the sliding grafting of the inner chamber bottom of recess 7 has wedge 9, and wedge 9 is located one side of spacing dish 5.

Make its emery wheel body 2 dismouting simple and convenient under the effect of spacing bolt 4, slot 6, spacing dish 5, spring 8 and wedge 9, can carry out the dismouting fast, need not to use traditional extracting tool moreover, it is convenient fast when changing emery wheel body 2 like this.

As shown in fig. 2, a rectangular protrusion 13 is fixedly mounted on one side of the inner cavity of the limiting disc 5, a rectangular groove 14 is fixedly formed at one end of the driving shaft 1, and the rectangular protrusion 13 is located in the inner cavity of the rectangular groove 14.

The rectangular lug 13 and the rectangular groove 14 are matched to limit the position between the limiting disc 5 and the driving shaft 1, so that the limiting disc 5 can rotate along with the driving shaft 1 when the driving shaft 1 is selected.

As shown in fig. 1-2 and 3, a protective cover 10 is sleeved on the outer sides of the limiting disc 5 and the flange 3, a push plate 11 is fixedly connected to one side of the protective cover 10, and an anti-skid pad 12 is fixedly mounted on the inner cavity wall of the protective cover 10.
