Abstract
The utility model provides an improved grinding head structure which can ensure that bearings of a spindle and a fixed spindle shift towards the side far from a grinding wheel when the bearings are heated so that the grinding precision and effect of the grinding wheel can not be affected by the thermal deformation of the spindle and the fixed spindle, instead the grinding precision and quality of the grinding wheel is improved. The improved grinding head structure comprises a wheel spindle, and the wheel spindle is connected with an electric motor through a belt pulley and a belt which are sleeved outside the wheel spindle; the wheel spindle is arranged on a shell, and the shell is arranged on a dragging plate; the wheel spindle is sleeved with bearings at the joint part of the wheel spindle and the shell; the bearing arranged near one side of the belt pulley is a carrying bearing, and the bearing at the other side is provided with a spindle ring flange on the outer end surface; and a grinding head is arranged in the spindle ring flange. The improved grinding head structure is characterized in that the bearing at the other side is an angular contact ball bearing.
Description
(1) technical field
The utility model relates to material grinding fine finishining field, is specially the modified grinding wheel head structure.
(2) background technology
Existing grinding wheel head structure, behind the bearing heating of main shaft and fixed main shaft, the thermal deformation meeting of main shaft causes main shaft to emery wheel one side displacement, has influence on the grinding accuracy and the effect of emery wheel.
(3) summary of the invention
At the problems referred to above, the utility model provides the modified grinding wheel head structure, and it can satisfy behind the bearing heating of main shaft and fixed main shaft, and the thermal deformation of main shaft can not have influence on emery wheel, has improved the grinding accuracy and the quality of emery wheel.
Its technical scheme is such: it comprises grinding wheel spindle, described grinding wheel spindle is connected motor by the belt pulley that is enclosed within its outside with belt, described grinding wheel spindle is installed on housing, described housing is installed on planker, the described grinding wheel spindle place that combines with described housing, described grinding wheel spindle is set with bearing, near belt pulley one side bearing is loading bearing, its outer face of the bearing of opposite side is pressed with the spindle flange dish, bistrique is installed on described spindle flange dish, it is characterized in that: the bearing of described opposite side is an angular contact ball bearing.
It is further characterized in that:
Described angular contact ball bearing has two; Described two angular contact ball bearings are arranged back-to-back; Separate with internal axle sleeve, outer shaft between described two angular contact ball bearings; Described grinding wheel spindle middle part is with bearing holder (housing, cover); Described bearing holder (housing, cover) one end is by two nuts and described grinding wheel spindle axial restraint; The described bearing holder (housing, cover) other end press-fit in described angular contact ball bearing one side inner ring end face; Described internal axle sleeve is placed in described grinding wheel spindle, and described outer shaft is embedded in described housing.
In the said structure of the present utility model, owing to adopted angular contact ball bearing, defining angular contact bearing can only be to away from emery wheel one side displacement, so after grinding wheel spindle and angular contact bearing heating, angular contact bearing is to moving away from emery wheel one lateral deviation, thereby the thermal deformation of grinding wheel spindle can not have influence on the grinding accuracy and the effect of emery wheel, has improved the precision and the quality of wheel grinding.
