Description
Technical field
This utility model is related to bushing dismounting specific purpose tool, more particularly, to a kind of oil pump bushing dismounting device.
Background technology
Oil pump is the hydraulic test in pulp and paper making extensive utilization.Wherein in wash engine hydraulic pressure main system, oil is installed
Pump, after longtime running, its axle envelope and wear ring wear and tear, and produce oil pump shaft envelope oil leakage phenomenon.But in more resleeve because bushing is not having
In the case of having special extracting tool, when directly using tradition to draw horse to dismantle oil pump bushing, because working space is limited, draw the horse cannot
Exert oneself, or even cannot remove, time length, just influence whether to produce, and increase maintenance manpower cost；And do not allow to be broken with gas cutting
Bad property is removed, it is to avoid the foreign body such as scum enters inside oil pump, causes the part rejection such as axle envelope.
Utility model content
In view of this, this utility model provides a kind of oil pump bushing dismounting device, solves bushing dismounting difficulty, rapid wear
Bad problem.
The technological means that this utility model adopts are as follows：A kind of oil pump bushing dismounting device, including fixture, first collar and
Second collar, described fixture includes pulling claw, pulling seat and screw rod, and described pulling claw is arranged on described pulling seat, and described screw rod is arranged in
The center of described pulling seat, described first set is equipped with the groove matching with described pulling claw, and described first collar is by two
Semi-ring forms, and described second collar is socketed on described first collar.
Preferably, described first collar and second collar are metal material and make.
Preferably, the height of described first collar is more than the height of described second collar.
Preferably, described second collar is socketed in the lower end of described first collar.
Preferably, described fixture is to draw horse.
Using a kind of oil pump bushing dismounting device provided by the utility model, have the advantages that, using first
The collar is socketed on described bushing, and second collar matches first collar, reinforces bushing, reuses fixture matching groove, make
First collar easy stress and not falling off in dismounting, reuse fixture and grip first collar and bushing is taken out, there is easy behaviour
Work, effect that is laborsaving and not damaging oil pump.
Brief description
Fig. 1 is a kind of schematic cross-section of this utility model oil pump bushing dismounting device；
Fig. 2 is main shaft in a kind of this utility model oil pump bushing dismounting device, first collar, the bowing of second collar and bushing
View.
In figure：1 oil pump body, 2 main shafts, 3 bushings, 4 fixtures, 5 first collars, 6 second collars, 41 pulling claws, 42 pulling seats, 43
Screw rod.
Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As shown in Figure 1, 2：A kind of oil pump bushing dismounting device, including fixture 4, first collar 5 and second collar 6, described
Fixture 4 is to draw horse, and including pulling claw 41, pulling seat 42 and screw rod 43, described pulling claw 41 is arranged on described pulling seat 42, described screw rod 43
It is arranged in the center of described pulling seat 42, described first collar 5 is provided with the groove 51 matching with described pulling claw 41, described recessed
Groove 51 is matched with described pulling claw 41, is easy to draw horse that described bushing 3 is taken out separation, is hardly damaged part.Described first collar 5
It is made up of two semi-rings, described second collar 6 is socketed on described first collar 5, described first collar 5 and second collar 6 are
Circular.Wherein, oil pump includes oil pump body 1, main shaft 2, bushing 3, described main shaft 2 located at the center of described oil pump body 1,
Described bushing 3 is socketed on described main shaft 2.On described bushing 3, described second collar 6 is socketed in institute to described first collar 5
State on first collar 5, described fixture 4 is matched with described first collar 5.Described first collar 5 is made up of two semi-rings, two
Semi-ring is easily socketed in the lower section of described bushing 3 when using.Described first collar 5 and second collar 6 are metal material and make,
It is carbon steel or stainless steel material is made, it is preferred that being processed into using carbon steel.The height of described first collar 5 is more than
The height of described second collar 6, so that the fixation of described second collar 6 packs tightly first set ring 5, makes first collar 5 and bushing 3
Difficult for drop-off during dismounting, second collar 6 is socketed in the lower end of first collar 5, and what the upper end of first collar 5 was provided with
Groove 51 is easy to match with pulling claw 41, reinforces first collar 5 so that bushing 3 is more adjacent to first collar 5 from lower end, is easy to
Described bushing 3 is taken out.
Operation principle：It is preferred that using the horse of drawing of three-jaw, the length of pulling claw 41, the spacing of pulling claw 41 and screw rod 43
Length, to adapt to the main shaft 2 of diameter and axially mounted depth.Described first collar 5 fixedly sleeved on described bushing 3, then
Second collar 6 is socketed on first collar 5, plays the effect of reinforcing.During use, top for screw rod 43 main shaft 2 that is positioned is pushed up
The position of end adjustment pulling claw 41, makes pulling claw 41 link up with the groove 51 on first collar 5, coordinates on screw rod 43 using spanner,
Rotary screw 43 makes pulling claw 41 drive first collar 5 and bushing 3 mobile dismounting axially outward.
In sum, using a kind of oil pump bushing dismounting device provided by the utility model, second collar 6 fixes first
The collar 5, on bushing 3, fixture 4 is matched first collar 5 with first collar 5, and bushing 3 is disassembled by easy labour-saving,
It is difficult to oil pump body 1, main shaft 2, bushing 3 etc. causes to damage.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement done etc., should be included in this utility model
Within the scope of protection.
