Background technology
, used as vitals that is fixed and reducing load coefficient of friction is played during mechanical rotation, it is in mechanical engineering for bearing
There is irreplaceable effect in field.For example：The wheel of walking-aided wheelchair car needs to install bearing ability smooth rotation；Prior art
In, bearing press-in is completed by pushing machine using some bearings and is installed, so as to improve the efficiency of machinery production.But at present
Some bearings push the wheel bearing installation that machine is not appropriate for walking-aided wheelchair car, set in the urgent need to looking for a kind of suitable bearing to push
The standby bearing to install walking-aided wheelchair car wheel.
Utility model content
For problem above, the purpose of this utility model is to provide a kind of wheel chair wheel bearing pressing machine structure, can be with root
The press-in height of depression bar is adjusted according to the different model of bearing, once simultaneously the bearing of wheel both sides bearing block can be pressed into into
It is interior.
The technical solution of the utility model is achieved in the following ways：A kind of wheel chair wheel bearing pressing machine structure, bag
Support, base and lower support are included, the center of described upper support is provided with hydraulic cylinder, and hydraulic cylinder is connected with depression bar, lower support
Center is provided with base, and step, wheel and top chock are sequentially provided with base, and bearing master is provided with the centre bore of wheel
Axle, upper bearing (metal) and lower bearing, it is characterised in that：The center of described depression bar and the axis coinciding of wheel, hydraulic cylinder drives depression bar
Downwards, the upper bearing (metal) and lower bearing of wheel both sides are pressed in top chock and step.
Two sides that hydraulic cylinder is supported on described are additionally provided with nut, for adjusting the impulse stroke of hydraulic cylinder.
The base middle is provided with bearing spindle, and the centrage of the bearing spindle overlaps with depression bar centrage.
The depression bar bottom is provided with depression bar bottom hole along center, and diameter and the bearing spindle in hole are gap cooperation so that
Bearing spindle can be entered in the hole of depression bar bottom.
This utility model, can adjust the press-in height of depression bar according to the different model of bearing, and depression bar connects with bearing
Contacting surface is less, is once pressed into that success rate is high, and the bearing pressing machine structure is reasonable in design, simple structure, easy to operate.
Description of the drawings
Fig. 1 is this utility model complete machine structure schematic diagram；
Fig. 2 is this utility model press structure schematic diagram；
Fig. 3 is the whole machine partial structural diagram of this utility model.
In figure：1 hydraulic cylinder, support, 3 depression bars, 4 upper bearing (metal)s, 5 bases, 6 times supports, 7 lower bearings, 8 wheels, 9 bearings on 2
Main shaft, 10 nuts, 11 steps, 12 depression bar bottom holes, 13 top chocks.
Embodiment
Known by Fig. 1, a kind of wheel chair wheel bearing pressing tool, by hydraulic cylinder 1, upper support 2, depression bar 3, upper bearing (metal) 4, base
5th, it is lower to support 6, lower bearing 7, wheel 8, bearing spindle 9, nut 10, step 11, depression bar bottom hole 12,13 groups of top chock
Into.The hydraulic cylinder 1 supports 2 vertically to fix as driving force with upper, and the working line of hydraulic cylinder 1 is adjusted by two nuts 10
Journey；Move under the hydraulic-driven power effect in the vertical direction of down-pressed pole 3；The base 5 is arranged on the base plate center of lower support 6
Between position, the middle of the base 5 is provided with bearing spindle 9, and the centrage of the bearing spindle 9 overlaps with the centrage of depression bar 3；
Depression bar bottom hole 12 is opened in the bottom of the depression bar 3 along center, and diameter and the bearing spindle 9 in depression bar bottom hole 12 are matched somebody with somebody using gap
Close；Down-pressed pole 3 is driven to move downward in forcing press, bearing spindle 9 is entered in depression bar bottom hole 12, depression bar 3 continues fortune downwards
It is dynamic, upper bearing (metal) 4 and lower bearing 7 are pressed in the step 11 and top chock 13 of the both sides of wheel 8.
With reference to Fig. 2, Fig. 3, this example is illustrating the course of work of the present utility model：Drive down-pressed pole 3 downward in hydraulic cylinder 1
Motion, bearing spindle 9 entered in depression bar bottom hole 12, and depression bar 3 continues to move downward, depression bar bottom face and connecing that institute last item holds
Contacting surface is equal in magnitude, and the press-in effect of bearing is ensured using reducing by the way of contact surface, and the damage of parts of bearings is avoided as far as possible,
So depression bar bottom contacts with the contact surface of bearing, and upper bearing (metal) 4 is pressed in top chock 13, and the pressure of depression bar 3 continues to act on
On wheel 8, and then the lower bearing 7 of lower section is also pressed in the step 11 of wheel 8, so through one action, just may be used
To be enclosed within bearing spindle 9, and the upper bearing (metal) 4 and lower bearing 7 positioned at the both sides of wheel 8 is pressed into the top chock of the both sides of wheel 8
13 and step 11 in, improve work efficiency.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure made using this utility model description or equivalent flow conversion, or directly or indirectly it is used in wheel-chair
Wheel technical field, is included in the same manner in scope of patent protection of the present utility model.
