Abstract

The utility model relates to an electronic unit pump and particularly relates to a plunger structure of an electronic unit pump. The plunger structure comprises a cylindrical plunger body, wherein the cylindrical plunger body comprises a first cylinder, a second cylinder and a third cylinder which are integrally connected; the diameters of the first cylinder, the second cylinder and the third cylinder are gradually reduced in sequence from top to bottom; the first cylinder is provided with an annular groove; a circular cone platform is arranged on the lower end of the third cylinder. The plunger structure is characterized in that a cylindrical annular belt is arranged on the lower end of the second cylinder. The diameter of the cylindrical annular belt is equal to the diameter of the first cylinder. Chamfers are arranged on the two ends of the plunger body. The plunger structure of the electronic unit pump, provided by the utility model, has the beneficial effects that a plunger is easy to clamp in the machining process and the machining efficiency and quality are improved.

Description

A kind of electronically controlled unit pump piston structure
Technical field
The utility model relates to electronically controlled unit pump, relates in particular to a kind of electronically controlled unit pump piston structure.
Background technique
Electronically controlled unit pump plunger coupled parts quality of fit is high, and difficulty of processing is large, and operation is various, and the process-cycle is long.When Excircle machining, need to pass through the operations such as corase grind, fine grinding and super grinding, and need conical surface location, two ends.Because cylindrical two diameter of plunger body does not wait, be not easy to be installed, so work efficiency is low.
The model utility content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of electronically controlled unit pump piston structure.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of electronically controlled unit pump piston structure, comprise cylindric plunger body, described plunger body comprises the first cylindrical body, the second cylindrical body and the three cylindrical body that diameter from top to down successively decreases successively and is connected as a single entity, described the first cylindrical body is provided with circular groove, the lower end of described three cylindrical body is provided with circular cone, it is characterized in that, be provided with cylindrical endless belt in the described second cylindrical lower end.
The diameter of described cylindrical endless belt equates with described the first cylinder diameter.
The two ends of described plunger body are provided with chamfering.
The beneficial effects of the utility model are: owing on plunger body, having increased cylindrical endless belt, neither affect plunger and use, make again plunger in course of working, be convenient to be installed, improved work efficiency and quality.
The accompanying drawing explanation
Fig. 1 is the piston structure schematic diagram of prior art;
Fig. 2 is piston structure schematic diagram of the present utility model.
In Fig. 1 and Fig. 2, the 1, first cylindrical body; 2, circular groove; 3, the second cylindrical body; 4, cylindrical endless belt; 5, three cylindrical body; 6, chamfering; 7, circular cone.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only be used to explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, be existing plunger pump structure schematic diagram.
As shown in Figure 2, a kind of electronically controlled unit pump piston structure, comprise cylindric plunger body, described plunger body comprises the first cylindrical body 1, the second cylindrical body 3 and the three cylindrical body 5 that diameter from top to down successively decreases successively and is connected as a single entity, described the first cylindrical body 1 is provided with circular groove 2, the lower end of described three cylindrical body 5 is provided with circular cone 7, in the lower end of described the second cylindrical body 3, is provided with cylindrical endless belt 4.
The diameter of described cylindrical endless belt 4 and described the first cylindrical body 1 equal diameters.
The two ends of described plunger body are provided with chamfering 6.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
