Abstract
The utility model discloses a kind of bearing inner race raceway groove grinding frocks, bearing inner race Internal hole positioning axis is connected with machine tool chief axis including one, one is fixed on revolution fulcrum on lathe, between the revolution fulcrum hinged platen bar both ends, pressing plate bar one end connection driving cylinder, the other end is equipped with pressing plate, when the mandril of driving cylinder is in elongation state, pressing plate compresses the bearing inner race being mounted on bearing inner race Internal hole positioning axis.It is lever principle mainly to have used, power utilization compressed air clean energy resource, not only environmental protection but also cleaning.It is simple in structure, it is easy to process.Protection and maintenance point is mainly the lubrication for turning round fulcrum and cylinder, as long as daily once.Workload is little.
Description
Technical field
The utility model is related to the grindings of bearing inner race raceway groove, and in particular to bearing inner race raceway groove grinding frock.
Background technology
In bearing inner race raceway groove grinding process, inner ring needs Internal hole positioning and the device of end face compression.Original device
It is to have a screw hole in the centre of endoporus locating shaft, then passes through pressing plate with screw.Inner ring is compressed by tightening screw.It is existing
Problem is the turn of the screw and to wear the time of pressing plate too long, and pressure is again uneven.In order to solve this problem, determine using cylinder-pressing
Mode improves efficiency to reduce the time.
The content of the invention
The utility model is directed to the situation of the prior art, provides bearing inner race raceway groove grinding frock, mainly uses
It is lever principle, power utilization compressed air clean energy resource, not only environmental protection cleaning again.It is simple in structure, it is easy to process.Protection and maintenance
The point mainly lubrication of revolution fulcrum and cylinder, as long as daily once.Workload is little.
In order to solve the above technical problems, the technical solution that the utility model uses is：The grinding of bearing inner race raceway groove is used
Frock is connected with machine tool chief axis bearing inner race Internal hole positioning axis including one, one is fixed on revolution fulcrum on lathe, the revolution
Between fulcrum hinged platen bar both ends, pressing plate bar one end connection driving cylinder, the other end is equipped with pressing plate, drives at the mandril of cylinder
When elongation state, pressing plate compresses the bearing inner race being mounted on bearing inner race Internal hole positioning axis.
As the preferred of said program, driving cylinder is fixed on lathe.
The beneficial effects of the utility model are：
The pressure of the turn of the screw is substituted with pneumatic pressure, operative employee is made not have to the turn of the screw, alleviates workload, and gas
The pressing force for pressing stabilization ratio the turn of the screw is reliable and stable.
It the turn of the screw and wears the time action of pressing plate and is completed by cylinder, shorten the clamping time, improve efficiency, production effect
Rate improves more than 30%.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
With reference to embodiment, specific embodiment of the present utility model is further described.
As shown in Figure 1, bearing inner race raceway groove grinding frock, bearing inner race Internal hole positioning is connected with machine tool chief axis including one
Axis 2, one is fixed on the revolution fulcrum on lathe 1, described to turn round between 5 both ends of fulcrum hinged platen bar, the connection of pressing plate bar one end
Cylinder 7 is driven, the other end is equipped with pressing plate 4, and when the mandril 6 of cylinder being driven to be in elongation state, pressing plate, which compresses, to be mounted in bearing
Enclose the bearing inner race 3 on Internal hole positioning axis.
Driving cylinder is fixed on lathe.
Wherein, turning round fulcrum includes a pedestal 8, and an axis vertical with the end face, the axis are set on the end face of the pedestal
It is inserted into the hole 9 on pressing plate bar.In this scenario, axis can coordinate with base rotation, and be fixed with pressing plate bar；Or axis and pressing plate bar
It is rotatably assorted, and is fixed with pedestal；Or other pressing plate bars can be around the structure that revolution fulcrum rotates.
Operation principle：The straight line of driving cylinder on lathe is fixed on toward left movement, pressing plate bar is pulled, due to there is revolution fulcrum
Effect pressing plate bar by turn round fulcrum rotate（Lever principle）, unclamp pressing plate and bearing inner race.Bearing can so be taken down
Inner ring.After second bearing inner race is attached on axis, the straight line of cylinder promotes pressing plate bar, due to there is revolution branch toward open movement
The effect pressing plate bar of point is rotated by turning round fulcrum（Lever principle）, pressing plate is made to compress bearing inner race.It starts to work.
Variation, the utility model on the basis of the utility model to the shape of product, size, color and combination
Product overall dimension, the change of color are all in the claimed scope of the utility model.
