Fixing with rotating disk, the other end of turning handle is fixed with extension bar.Turning handle is fixed by nut with rotating disk, unclamps nut, Ke Yizhuan
Dynamic turning handle, makes turning handle drive the extension bar conversion extension bar position relative to rotating disk radial direction, thus changes extension bar and be relatively fixed folder
Upper and lower relation between the push rod of tool, enables extension bar against the push rod in different size of retainer ring, thus is applicable to not
Process with the axle of external diameter size.
Described push rod is threadeded with retainer ring.So, push rod stretches out the length of retainer ring and can also regulate, with against stretching
Rod.
Described center of turntable has through hole, and described first grinding head is fixed in described through hole by clutch shaft bearing, described
Rotating disk is fixed with rotation seat by the second bearing.So, the rotation of rotating disk does not interferes with the first grinding head, and rotating disk can also lead to
Cross rotation seat to fix.
The beneficial effects of the utility model are, axle centre-hole lapping machine of the present utility model, and the first grinding head and second grinds
Bistrique can be the most countershaft two ends carry out the processing of centre bore, working (machining) efficiency is high, and the first grinding head and the second grinding head equal
It is fixing, it is ensured that the first grinding head and the axiality of the second grinding head, the centre bore at the axle two ends processed coaxial
Degree height；And being provided with turning handle and extension bar, rotate turning handle and can regulate the height of extension bar, rotating push rod can regulate push rod and stretch
Go out the length of retainer ring, so that rotating driving device can be adjusted for the axle of various outer diameter, make same axle center
Hole grinder can be processed for the axle of various outer diameter, and adjustable extent can be set by the length arranging turning handle and push rod
Fixed, strong adaptability.
