Abstract
The invention discloses a kind of bearing inner race raceway groove grinding frock, bearing inner race Internal hole positioning axle 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 connects drive cylinder, the other end is provided with pressing plate, when the push rod of drive cylinder is in elongation state, pressing plate compresses the bearing inner race being arranged on bearing inner race Internal hole positioning axle.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 construction, 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 present invention relates to the grinding 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 oversize, 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 present invention is directed to the situation of prior art, there is provided bearing inner race raceway groove grinding frock, it is thick stick mainly to have used
Rod principle, power utilization compressed air clean energy resource, not only environmental protection but also cleaning.It is simple in construction, it is easy to process.Protection and maintenance point master
If turning round the lubrication of fulcrum and cylinder, as long as daily once.Workload is little.
In order to solve the above technical problems, one aspect of the present invention is：Bearing inner race raceway groove grinding frock,
Bearing inner race Internal hole positioning axle is connected with machine tool chief axis including one, one is fixed on revolution fulcrum on lathe, the revolution fulcrum
Between hinged platen bar both ends, pressing plate bar one end connection drive cylinder, the other end is provided with pressing plate, and the push rod of drive cylinder, which is in, to be stretched
During long status, pressing plate compresses the bearing inner race being arranged on bearing inner race Internal hole positioning axle.
As the preferred of such scheme, drive cylinder is fixed on lathe.
The beneficial effects of the invention are as follows：
The pressure of the turn of the screw is substituted with pneumatic pressure, operative employee is not had to the turn of the screw, alleviates workload, and air pressure is steady
It is fixed more reliable and more stable than the thrust of the turn of the screw.
The turn of the screw and wear the time action of pressing plate and completed by cylinder, shorten the clamping time, improve efficiency, production effect
Rate improves more than 30%.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
With reference to embodiment, the embodiment of the present invention is further described.
As shown in figure 1, bearing inner race raceway groove grinding frock, including one is connected bearing inner race Internal hole positioning with machine tool chief axis
Axle 2, one is fixed on the revolution fulcrum on lathe 1, described to turn round between the both ends of fulcrum hinged platen bar 5, the connection of pressing plate bar one end
Drive cylinder 7, the other end is provided with pressing plate 4, and when the push rod 6 of drive cylinder is in elongation state, pressing plate, which compresses, to be arranged in bearing
The bearing inner race 3 enclosed on Internal hole positioning axle.
Drive cylinder is fixed on lathe.
Wherein, revolution fulcrum includes a base 8, and an axle vertical with the end face, the axle are set on the end face of the base
Insert in the hole 9 on pressing plate bar.In this scenario, axle can coordinate with base rotation, and be fixed with pressing plate bar；Or axle and pressing plate bar
It is rotatably assorted, and is fixed with base；Or other pressing plate bars can be around the structure of revolution fulcrum.
Operation principle：The straight line of drive 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 turning round fulcrum（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 axle, 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 by turning round fulcrum（Lever principle）, pressing plate is compressed bearing inner race.Start working.
It is overall to the changing of the shape of product, size, color and combination, product of the present invention on the basis of the present invention
Appearance and size, the change of color are all in scope of the present invention.
