Abstract
A kind of automobile p-type pump plunger snap ring dismantling device, it is made up of stamen bar 5 and installation resilient sleeve 6, stamen bar 5 is cylinder, there are conical round table 51 and top 52 in its lower end, installation resilient sleeve 6 is hollow circular-tube, and its upper end is guide sleeve 61, and lower end is resilient sleeve 62, there is longitudinal elongated slot 63 in resilient sleeve 62, the wall thickness of guide sleeve is more than the wall thickness of resilient sleeve.The present invention is not due to using as above designing, compared with Traditional Man is than dismounting, damaging fine-limit work surface and the deep hole of plunger, having the advantages that using flexible, simple to operate, labor intensity is low, disassembly efficiency is high.
Description
Technical field
The present invention relates to a kind of special deep hole snap ring dismantling device, particularly a kind of automobile p-type pump plunger snap ring dismounting work
Tool.
Background technology
At present, in the prior art, it is also no to be used for manually-operated deep hole snap ring dismantling device.The pump of automobile p-type pump
There are plunger 2 and spring pad 3 in the deep hole of body 1, there is snap ring 4 on plunger 2（As shown in Figure 1）.It is existing to dismount snap ring in the deep hole of the pump housing 1
4 mode is：Snap ring 4 is manually dismounted in the deep hole of the pump housing 1 using conventional tools such as bottle opener, pliers.Due in the deep hole of the pump housing 1
Dismounting snap ring 4 does not have how much space so that dismounting snap ring 4 is extremely difficult, is also afraid of fine-limit work surface and the pump housing of damage plunger 2
1 inner walls of deep holes, it is both inconvenient, lose time again.
The content of the invention
The purpose of the present invention is to overcome the above-mentioned deficiency of prior art, and provides a kind of convenient disassembly, and disassembly efficiency is high, also
The automobile p-type pump plunger snap ring dismantling device of deep hole will not be scratched.
The technical scheme is that：A kind of automobile p-type pump plunger snap ring dismantling device, by stamen bar and elastic set group is installed
Into there are conical round table and top in stamen bar lower end, and installation resilient sleeve is hollow circular-tube, and its lower end is resilient sleeve, is had in resilient sleeve vertical
To elongated slot.
Further technical scheme is the present invention:Stamen bar is cylinder.
Further technical scheme is the present invention:It is guide sleeve to install elastic set upper side.
Technical scheme of the invention further is：The wall thickness of guide sleeve is more than the wall thickness of resilient sleeve.
The present invention is not due to using as above designing, compared with Traditional Man is than dismounting, damaging the fine-limit work surface of plunger
And deep hole, there is the advantages that using flexible, simple to operate, labor intensity is low, disassembly efficiency is high.
The detailed content of the present invention is further described below in conjunction with the drawings and specific embodiments.

Embodiment
As shown in Figure 2：A kind of automobile p-type pump plunger snap ring dismantling device, it is made up of stamen bar 5 and installation resilient sleeve 6, stamen bar
5 be cylinder, and there are conical round table 51 and top 52 in its lower end, and installation resilient sleeve 6 is hollow circular-tube, and its upper end is guide sleeve 61,
Lower end is resilient sleeve 62, there is longitudinal elongated slot 63 in resilient sleeve 62, and the wall thickness of guide sleeve is more than the wall thickness of resilient sleeve.
The present invention application method and operating process be：
When needing to dismantle automobile p-type pump plunger snap ring, the present invention is put into the deep hole of the pump housing 1, with the top 52 of stamen bar 5
Plunger 2 is withstood to be allowed to move down（As shown in Figure 3）, and the snap ring 4 on plunger 2 by the spring pad 3 in the deep hole of the pump housing 1 due to being kept off
Firmly, depart from plunger 2 and be enclosed in the conical round table 51 of stamen bar 5, so as to easily take apart snap ring 4 from plunger 2（Such as figure
Shown in 4）；
When needing to install automobile p-type pump plunger snap ring 4, snap ring 4 is sleeved on stamen bar 5 of the present invention first（Such as Fig. 5 institutes
Show）, then the present invention is installed into resilient sleeve 6 and is sleeved on stamen bar 5 of the present invention, and snap ring 4 is elapsed to the taper circle of the lower end of stamen bar 5
On platform 51（As shown in Figure 6）, then the present invention is put into the deep hole of the pump housing 1, with the top 52 of stamen bar 5 withstand plunger 2 be allowed to
Lower movement（As shown in Figure 7）, the snap ring 4 in conical round table 51 then withstands on by the resilient sleeve 62 of present invention installation resilient sleeve 6 lower end
On spring pad 3, keep installation resilient sleeve 6 motionless at this, stamen bar 5 is up carried, snap ring 4 is slipped to the annular groove of plunger 2
It is interior（As shown in Figure 8）, so as to which easily snap ring 4 is installed on plunger 2.
