The described grinding attachment that has rotatable emery wheel is installed in the mill bar in this bearing block by the bearing block clamper, and the emery wheel and the rotatable emery wheel thereof that are contained in this mill rod end head are formed.
Described drive unit is made up of the transmission mechanism that is connected into by big belt wheel, V-belt and small pulley that is installed in motor on the motor cabinet, be contained on the motor shaft, and this small pulley is connected with the afterbody of the mill bar of described grinding attachment.
Described emery wheel closely is connected with the mill bar by round nut and pressing plate, and axle and end cap that the mill bar is installed by two ends are installed in the eccentric bearing block, and bearing block is pressed on by clamper on the cutter platform of engine lathe, and the afterbody of mill bar is connected with small pulley by key.
Described mill rod bearing seat and the emery wheel that is contained in this mill rod end head penetrate in the dresser, the mill rod bearing seat and the overall radial dimension of emery wheel that is contained in this mill rod end head less than work piece diameter of bore, axial length greater than work piece length.
Described dresser is a convex shape cylinder, is provided with the clamping screw along its circumferencial direction, and lug boss is provided with diamond pen.
According to engine lathe of the present utility model inner hole grinding device, the small pulley that is connected with the mill bar that has rotatable emery wheel links by V-belt and the big belt wheel that is contained on the motor, big belt wheel is by driven by motor, thereby make the emery wheel rotation, whole device clamping is on lathe cutter platform, thereby drive the whole length of grinding part that axially moves by the lathe saddle, radial feed is finished by the lathe middle carriage, and grinding diameter of bore to pattern requires size.
The beneficial effects of the utility model are, can be on engine lathe the endoporus of grinding slewing parts, and improve endoporus dimensioned precision and surface roughness effectively, satisfy the assembly precision requirement, and this apparatus structure is simple, easily processing and manufacturing.
The effect of eccentric bearing block is: in order to guarantee whole device enough intensity is arranged, the bearing block of long tubular must have enough wall thickness.But the diameter of emery wheel but can not be excessive, otherwise can increase the contact arc length of emery wheel outer surface and workpiece bore area, increases grinding force, thereby cause the vibration of whole device.In order to prevent vibration, will adopt the emery wheel of minor diameter, surpass the bearing block body for making sand synthetic fibre cylindrical, will dwindle the bearing block body, this has reduced the intensity of whole device again.Adopt the design of bearing and bearing block off-centre just can address this problem.Corresponding thickening and eccentric reciprocal wall thickness can guarantee the intensity of whole device.And can make emery wheel deflecting away from the bigger radial dimension of bearing block in the radial direction, be utilized.
