Abstract
An automobile P type pump plunger snap ring dismantling device comprises a core rod (5) and a mounting elastic sleeve (6), wherein the core rod (5) is in a cylindrical shape, a cone-shaped round table (51) and a piercing head (52) are arranged at the lower end of the core rod (5), the mounting elastic sleeve (6) is a hollow round tube, the upper end of the mounting elastic sleeve (6) is a guide sleeve (61), the lower end of the mounting elastic sleeve (6) is an elastic sleeve (62) provided with a longitudinal long tank (63), and wall thickness of the guide sleeve is greater than that of the elastic sleeve. By means of the adoption of the design, compared with traditional manual disassembly and assembly, the automobile P type pump plunger snap ring dismantling device does not damage a precise working surface and a deep hole of a plunger and has the advantages of being flexible in use, simple in operation, low in labor intensity, high in disassembly and assembly efficiency, and the like.
Description
Technical field
The utility model relates to a kind of special-purpose deep hole snap ring dismantling device, particularly a kind of automobile P type pump plunger snap ring dismantling device.
Background technology
At present, in the prior art, also be not used in manually-operated deep hole snap ring dismantling device.Plunger 2 and spring pad 3 are arranged in the pump housing 1 deep hole of automobile P type pump, snap ring 4 (as shown in Figure 1) is arranged on the plunger 2.The mode that has dismounting snap ring 4 in the pump housing 1 deep hole now is: adopt conventional instrument manual work dismounting snap rings 4 in the pump housing 1 deep hole such as bottle opener, pliers.Because dismounting snap ring 4 does not have much spaces in the pump housing 1 deep hole, make dismounting snap ring 4 quite difficult, also be afraid of the fine-limit work surface and the pump housing 1 inner walls of deep holes of damage plunger 2, both inconvenient, lose time again.
Summary of the invention
The purpose of the utility model is the above-mentioned deficiency that overcomes prior art, and a kind of easy accessibility is provided, and dismounting efficient is high, also can not scratch the automobile P type pump plunger snap ring dismantling device of deep hole.
The technical scheme of the utility model is: a kind of automobile P type pump plunger snap ring dismantling device; Be made up of stamen bar and installation resilient sleeve, there are taper round platform and top in stamen bar lower end, and the installation resilient sleeve is a hollow circular-tube; Its lower end is a resilient sleeve, and elongated slot is longitudinally arranged on the resilient sleeve.
The further technical scheme of the utility model is: the stamen bar is cylindrical.
The further again technical scheme of the utility model is: the resilient sleeve upper end is installed is fairlead.
The utility model technical scheme further is: the wall thickness of fairlead is greater than the wall thickness of resilient sleeve.
The utility model is compared than dismounting with tradition is artificial owing to adopt as above design, does not damage the fine-limit work surface and the deep hole of plunger, has and uses flexibly, and is simple to operate, labour intensity is low, dismounting efficient advantages of higher.
Further describe below in conjunction with accompanying drawing and the specific embodiment detailed content the utility model.

The specific embodiment
As shown in Figure 2: a kind of automobile P type pump plunger snap ring dismantling device, to form by stamen bar 5 and installation resilient sleeve 6, stamen bar 5 is cylindrical; There are taper round platform 51 and top 52 in its lower end; It is hollow circular-tube that resilient sleeve 6 is installed, and its upper end is a fairlead 61, and the lower end is a resilient sleeve 62; Elongated slot 63 is longitudinally arranged on the resilient sleeve 62, and the wall thickness of fairlead is greater than the wall thickness of resilient sleeve.
The method for using and the operating process of the utility model are:
When needs dismounting automobile P type pump plunger snap ring; The utility model is put into the pump housing 1 deep hole; Withstand plunger 2 with the top 52 of stamen bar 5 and make it to move down (as shown in Figure 3); And snap ring on the plunger 24 is owing to blocked by the spring pad 3 in the pump housing 1 deep hole, breaks away from plunger 2 and is enclosed within on the taper round platform 51 of stamen bar 5, thereby easily snap ring 4 is taken apart (as shown in Figure 4) from plunger 2;
When needs are installed automobile P type pump plunger snap ring 4; At first snap ring 4 is sleeved on the utility model stamen bar 5 (as shown in Figure 5); Again the utility model is installed resilient sleeve 6 and be sleeved on the utility model stamen bar 5, and snap ring 4 passed on the taper round platform 51 of stamen bar 5 lower ends (as shown in Figure 6), then the utility model is put into the pump housing 1 deep hole; Withstand plunger 2 with the top 52 of stamen bar 5 and make it to move down (as shown in Figure 7); 4 resilient sleeve 62 by the utility model installation resilient sleeve 6 lower ends of snap ring on the taper round platform 51 withstand on the spring pad 3, keep installation resilient sleeve 6 motionless at this, and stamen bar 5 is up carried; Make snap ring 4 be slipped to the annular groove interior (as shown in Figure 8) of plunger 2, thereby easily snap ring 4 is installed on the plungers 2.
