Description
Technical field
The present invention relates to Production of bearing equipment technical field, more particularly to one kind is easy to bearing outer ring side to carry out at surface
The fixing device of reason.
Background technology
Bearing is that part that is fixed and reducing load coefficient of friction is played in mechanical transmission course, it may also be said to, when other
When parts produce relative motion each other on axle, for reducing power transmission process in coefficient of friction and holding shaft center
Fixed parts.Bearing is a kind of very important parts in contemporary plant equipment, and its major function is supporting machinery rotation
Swivel, to reduce mechanical load coefficient of friction of the equipment in transmission process, by the difference of motor element frictional property, bearing
Rolling bearing and the class of sliding bearing two can be divided into.Bearing outer ring side has to pass through surface treatment, bearing outer ring side before dispatching from the factory
Special utensil is generally needed to be fixed on bearing when face is surface-treated, but existing this appliances fixed effect is equal
It is not to meet very much the fixed of surface treatment to require, and it is with high costs, using also inconvenient, it is impossible to adapt to various sizes of bearing,
So that bearing outer ring side surface treatment effeciency is relatively low.
The content of the invention
The invention aims to shortcoming present in prior art is solved, and the one kind for proposing is easy to bearing outer ring side
The fixing device that face is surface-treated.
To achieve these goals, present invention employs following technical scheme：
A kind of fixing device for being easy to bearing outer ring side to be surface-treated, including fixed seat, set in the fixed seat
There is fixed support, the fixed support is provided with rotating shaft, gear is arranged with the rotating shaft, one end of the rotating shaft is provided with rotation
Handle, through gag lever post is provided with the fixed seat, the lower end of the gag lever post is provided with some sawtooth, and sawtooth is nibbled with gear
Close, bearing is arranged with the gag lever post, the inner ring of the bearing is provided with elastic supporting mechanism, and the elastic supporting mechanism is by upper
Support block, spring and lower support block composition, the spring is located between upper support block and lower support block, the upper support block and axle
The upper inside walls for holding inner ring offset, and the lower support block offsets with the downside inwall of bearing inner race, and up and down the two of the gag lever post
Side is arranged with two perforates, and upper support block and the lower width of support block match with the width of perforate, the gag lever post
Inside is provided with cavity, and left limit block and right limit block are provided with the cavity, is arranged with the left limit block and moves to left lever, institute
State and move to left the right-hand member of lever and be connected with the left end of upper support block by two first wires, the right-hand member for moving to left lever passes through
Two second wires are connected with the left end of lower support block, and the position of the first wire and the second wire is symmetrical, described
It is arranged with right limit block and moves to right lever, the left end for moving to right lever passes through the right-hand member of two the 3rd wires and upper support block
Connection, the lever that moves to right is connected by two the 4th wires with the right-hand member of lower support block, and the 3rd wire and the 4th steel
The position of silk thread is symmetrical, and two the first lock-screws are arranged with the gag lever post, and each first lock-screw is passed through
Wear gag lever post and offset with lever is moved to left, two the second lock-screws, and each second locking are arranged with the gag lever post
Screw offsets through gag lever post and with lever is moved to right.
Preferably, left retainer ring is arranged with the gag lever post, and left retainer ring is located between fixed seat and bearing, it is described
Left retainer ring is arranged with two connecting rods near the side of fixed seat, and every connecting rod is passed through away from one end of left retainer ring
Fasten reservation and extend, the fixed seat is provided with two the 3rd lock-screws, and each the 3rd lock-screw through fixation
Seat offsets with connecting rod, and the left retainer ring is provided with the first rubber ring, and the first rubber ring and bearing away from the side of connecting rod
Left end offset.
Preferably, right retainer ring is also arranged with the gag lever post, the right retainer ring is provided near the side of fixed seat
Second rubber ring, and the second rubber ring offsets with the right-hand member of bearing, and two the 4th locking screws are arranged with the right retainer ring
Follow closely, and each the 4th lock-screw offsets through right retainer ring and with gag lever post.
Preferably, the fixed seat and fixed support are integrally formed.
In the present invention, by shake swing handle so as to drive axis of rotation, and then pinion rotation can be driven, due to gear
And engagement, therefore gag lever post can be driven to move left and right, adjustable limit bar to suitable position is (i.e. according to required fixing bearing
Width adjusting gag lever post be located at fixed seat on the right side of length, in order to stabilize carrying out the fixation of bearing)；Treat that gag lever post is adjusted to conjunction
Behind suitable position, successively by left retainer ring, bearing and right Fixing shrink ring on gag lever post, using connecting rod adjust left retainer ring to
To connect rod locking using the 3rd lock-screw behind suitable position, so as to fix left retainer ring, due to the first wire, the
Two wires, the 3rd wire, the setting of the 4th wire, pulling move to left lever and move to right lever can cause support block and under
Support block move toward one another so that spring-compressed, then moves to left lever and moves to right lever regulation elasticity supporting mechanism position by movement
At the inner ring of bearing, then unclamp to move to left and lever and move to right lever, due to the elastic reaction of spring, upper support block is passed through spacing
The perforate of bar upper end offsets with the upper inside wall of bearing inner race, and lower support block is passed through perforate and the bearing inner race of gag lever post lower end
Lower inner wall offset, due to spring effect, upper support block and lower support block toward contrary direction move when, the first steel wire
Line and the pulling of the second wire move to left lever and move along left limit block, and the 3rd wire and the 4th wire are pulled and move to right lever
Along the movement of right limit block, after elastic supporting mechanism lives bearings completely from bearing inner race, then slightly draw toward two ends
It is dynamic to move to left lever and move to right lever so that bearing in the vertical direction adjusts to correct position and the left end of bearing and a left side are consolidated
Determine after the first rubber ring on ring offsets, rod locking will be moved left using two the first lock-screws, using two second lockings
Screw will move right rod locking, and right retainer ring is then moved again, by the right-hand member phase of the second rubber ring in right retainer ring and bearing
Support, recycle the 4th lock-screw to lock right retainer ring, thus, bearing is just fixed, treat that bearing outer ring side is processed
After finishing, the second lock-screw and the 4th lock-screw are backed out, remove right retainer ring, pulling moves to right lever, makes spring-compressed, with
After remove bearing；The setting of right limit block, plays a part of restriction and moves to right lever position, and the setting of left limit block is played
Restriction moves to left the effect of lever position.The present invention can effectively carry out the fixation of bearing, and fixed dynamics is moderate, can well meet axle
Bearing when bearing outer-ring side is surface-treated is fixed and required, and with low cost, simple operation, adapts to various sizes of axle
Hold so that the efficiency of bearing outer ring surface treatment increases significantly, is worthy to be popularized.
