For achieving the above object, the technical scheme that the utility model is taked is: a kind of cradle-type cone grinding attachment, and its main feature is to include and is fixed with bearing pin on base, is provided with cradle body on bearing pin, and cradle body rotates on bearing pin; Described cradle body is the U type, goes to the bottom to be the plane, and its center is provided with main shaft, and main shaft is located on the cradle body by clutch shaft bearing; Main shaft and flange seat are connected, and worm gear and main shaft are connected; Be provided with bearing in the cradle body bottom, worm shaft is located on the bearing by second bearing, and worm shaft is meshed with worm gear.
Described cradle-type cone grinding attachment, described cradle body and base both sides are provided with locating hole, have alignment pin to fix; After cradle body turns to required angle, base and cradle body are located by the both sides locating hole by alignment pin, both sides are fastenedly connected base and cradle body by pressing plate.
The upper end of described worm shaft is provided with handwheel, shakes handwheel and drives main axis rotation, thereby the workpiece on the flange seat is rotated.
Described cradle-type cone grinding attachment, described base both sides all have two 45 ° and 60 ° of locating holes that are distributed in different radius of circles, and all there are 0 ° and 7.5 ° of locating holes that are distributed in different radius of circles the cradle body both sides.
Described main shaft is provided with mohs tapered bore and can be connected with the emery wheel centralising device.
The beneficial effects of the utility model: 60 °, 75 °, 90 ° top cones of grinding flange plate type are a kind of process innovations on plain grinding, and it has solved the problem that cylindrical grinder can not long feed when the top cone of grinding cradle-type cone grinding attachment.Guaranteed the linearity of cone bus.It well solved traditional handicraft to the top tip of flange plate type can't grinding problem, enlarged the top scope of application of flange plate type.The grinding of top tip can improve the top machining accuracy of flange plate type own.Platen is motionless in the grinding process, and grinding wheel spindle is done traverse feed.Its simple to operate, easy to adjust, good rigidly, and expanded the range of application of surface grinding machine.
