Abstract
The utility model discloses a diesel cylinder body relating to a main body of the cylinder body. The main body of the cylinder body is provided with a bolt hole which can be fixedly connected with the pump box of the diesel. A curved surface which can be fixedly connected with the pump box of the diesel is provided on the outer surface of the main body of the cylinder body, and plane portions are provided for the bolt hole on both sides of the arc of the curved surface respectively. The utility model can achieve a tight connection between the cylinder body of the diesel and the pump box of the engine.
Description
Technical field
The utility model relates to the technical field of diesel engine, especially relates to a kind of cylinder of diesel engine.
Background technique
Motor monoblock pump on the diesel engine is connected with engine cylinder at present, and generally connect by dual mode: a kind of is embedded, promptly each monoblock pump unit is installed in the body of diesel engine, drives by camshaft; And another mode is at pump box of the outside increase of diesel engine machine, and cylinder of diesel engine is done corresponding change back and is connected with the pump box of diesel engine, drives by gear.Wherein, preceding kind of scheme is relatively difficulty of the embedded connection processing of diesel engine monoblock pump, and the motor change is bigger, is difficult for carrying out.And adopt back a kind of pump box and cylinder block ways of connecting with diesel engine, then between the two tightness is again a problem that is very difficult to solve after connection.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of cylinder of diesel engine, and it can effectively solve pump box and between the two tightness problem after cylinder block is connected on the diesel engine, and makes motor and pump box better realize being connected.
For solving the problems of the technologies described above, the technical solution of the utility model is: cylinder of diesel engine, relate to the cylinder block body, described cylinder block body is provided with the bolt hole that can fixedly connected with the diesel engine pump box, described this external surface of cylinder block is provided with the arc shaped surface that can be used for fixedly connected diesel engine pump box, and the both sides of described arc shaped surface circular arc are respectively equipped with the planar surface portion that described bolt hole can be set.
As a kind of optimal way, be respectively equipped with a bolt hole on the described planar surface portion.
Adopt the cylinder of diesel engine of said structure, fit with good surface by the one section circular arc that on the cylinder block body, is provided with corresponding pump box, while is each processing bolt hole in the top and the bottom of circular arc, adopt bolt that pump box is pressed on the arc surface of cylinder block body, thereby realize that pump box is connected with the tight of motor.This cylinder of diesel engine is changed little when install connecting, and convenient processing is with short production cycle, can effectively realize being connected of cylinder of diesel engine and pump box.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Accompanying drawing is the structural representation of cylinder of diesel engine of the present utility model.
Embodiment
With reference to accompanying drawing, a kind of cylinder of diesel engine of the present utility model is: the cylinder block body 1 that relates to diesel engine, the cylinder block body 1 of diesel engine can be fixedlyed connected with the pump box on the diesel engine, on the cylinder block body 1 of diesel engine, be provided with the bolt hole that to fixedly connected with the diesel engine pump box, in order can when connecting, to connect closely between the two, on cylinder block body 1 outer surface, be provided with arc shaped surface 2, be respectively equipped with the planar surface portion 3 that bolt hole can be set in the both sides of arc shaped surface 2 circular arcs, 4, adopt diesel engine pump box correspondingly, be also be provided with on the diesel engine pump box with the cylinder of diesel engine body on arc shaped surface 2 corresponding arcuate surface, like this, at cylinder of diesel engine with when pump box is connected, arcuate surface between the two fits tightly, and adopt bolt to cooperate, thereby cylinder of diesel engine and pump box are fixed together closely with bolt hole.Consider the convenience when cylinder of diesel engine is connected with pump box, under the preceding topic that does not influence the soundness that connects between the two, can adopt and on planar surface portion 3,4, be respectively equipped with a bolt hole.
Claims (2)
1, cylinder of diesel engine, relate to cylinder block body (1), described cylinder block body (1) is provided with the bolt hole that can fixedly connected with the diesel engine pump box, it is characterized in that: described cylinder block body (1) outer surface is provided with the arc shaped surface (2) that can be used for fixedly connected diesel engine pump box, and the both sides of described arc shaped surface (2) circular arc are respectively equipped with the planar surface portion (3,4) that described bolt hole can be set.
2, cylinder of diesel engine according to claim 1 is characterized in that: described planar surface portion is respectively equipped with a bolt hole on (3,4).
