Description
Technical field
The utility model is related to grinding machine field, and in particular to a kind of mounting structure of the work spindle of bearing grinder.
Background technology
The mounting structure of the work spindle of existing bearing grinder includes work spindle, sleeve and bearing group, work spindle
Two ends are supported in sleeve by bearing group, and bearing group is typically held out against on the step of work spindle by spacer ring or nut.If
Held out against using spacer ring and need to be separately equipped with bearing group, work spindle step with against spacer ring, due to spacer ring, step and bearing
The depth of parallelism of group three's counterface requires very high, causes high processing costs；If holding out against bearing group, nut and workpiece using nut
Spindle thread is connected, and the flatness of nut end face and requires very high with the perpendicularity of the centre of gyration of main shaft, again result in plus
Work high cost.In addition, sleeve is same with the required precision that bearing group is assembled very high, because sleeve is general by Boring machine processing, single
After Continuous maching, the internal diameter size of axial one end of sleeve is less than the internal diameter size of the other end, needs reprocessabilty, processing cost is same
Sample is very high.
Utility model content
Regarding to the issue above, the utility model provides a kind of mounting structure of the work spindle of bearing grinder, and it can be solved
Certainly each part matching part machining accuracy of the mounting structure of work spindle is high in the prior art, causes the technology of high processing costs to be asked
Topic.
Its technical scheme is such, and it includes work spindle, sleeve and bearing group, and the work spindle two ends lead to respectively
Bearing group is crossed to be supported in sleeve, it is characterised in that：Interference is connected with hydraulic expanding sleeve locking and opened respectively at the work spindle two ends
Provided with step, the side end face of bearing group one is resisted against on the end face of the step, another side end face by the expansion sleeve end
Face is held out against；Described larger one end of sleeve diameter size is provided with bulging joining sleeve, and the bulging joining sleeve includes mutual by the conical surface
The distensible ring and expansion set of cooperation, the expansion set are sheathed on outside the sleeve, and the distensible ring is held out against by jacking mechanism.
Further, the jacking mechanism includes the end cap being sheathed on the work spindle, and the end cap is filled provided with top
The collar flange of the distensible ring is simultaneously connected by bolt with the lathe bed of sleeve or grinding machine.
Further, the medial surface of the hydraulic expanding sleeve locking is respectively the first seal face and the second pressure positioned at internal channel both sides
Tight face, first seal face is more than the internal diameter of the second seal face close to corresponding bearing group and its internal diameter；The workpiece master
The radial dimension of the corresponding hydraulic expanding sleeve locking installation position of axle is more than the footpath of the non-hydraulic expansion sleeve installation position away from bearing group
To size and the internal diameter of the first seal face.
Further, the width of first seal face is more than the width of second seal face.
Further, the corresponding hydraulic expanding sleeve locking installation position of the work spindle and the non-hydraulic swelling away from bearing group
Set is provided with outer channel corresponding with the internal channel of hydraulic expanding sleeve locking between installation position.
The mounting structure of the work spindle of the utility model bearing grinder, it uses hydraulic expanding sleeve locking to hold out against bearing group, by
It is interference fit in hydraulic expanding sleeve locking and work spindle, one side end face holds out against bearing group, gone relative to bolt and spacer ring, hydraulic pressure
Expansion sleeve is only needed to consider the depth of parallelism for the side end face for holding out against bearing group, and the reduction of its difficulty of processing coefficient can be reduced and is processed into
This；It uses bulging joining sleeve, and expansion set is sheathed on outside sleeve, and distensible ring is held out against by jacking mechanism so that expansion set clamp sleeve
The larger one end of internal diameter size, so that the larger-size one end of sleeve diameter is able to shrink and is fastenedly connected with bearing group outer ring, from
And sleeve reprocessabilty is avoided, it reduce further processing cost.
