Abstract
The utility model discloses a split type diesel engine box body. The split type diesel engine box body comprises a main box body. The main box body is provided with a bent axle installation hole used for installation of a bent axle, and a cylinder sleeve installation hole used for installation of a cylinder sleeve. The main box body is formed by assembling a left main box body and a right main box body, the left main box body and the right main box body are formed in a casting mode, and the cylinder sleeve installation hole is formed in the assembly process of the left main box body and the right main box body. The main box body is divided into the left main box body and the right main box body along the central line of the cylinder sleeve installation hole, then the left main box body and the right main box body are formed in the casting mode, and therefore the shrinkage factor of the main box body is lowered, the installation accuracy of parts of a diesel engine is guaranteed, and the production efficiency is improved. In addition, due to the fact that the main box body is divided into the left main box body and the right main box body, in the machining process, the locating difficulty and the clamping difficulty of the left main box body and the right main box body are lowered, and the machining accuracy can be guaranteed.
Description
Technical field
The utility model relates to a kind of diesel engine, particularly relates to a kind of diesel engine box body, more specifically relates to a kind of Split type box body of single cylinder diesel.
Background technique
Because diesel engine has the advantages such as power is large, economic performance is good, so diesel engine is widely used in the fields such as industry, agricultural.Diesel engine mainly comprises casing, bent axle and cylinder etc., wherein, casing is for supporting and installing as component such as bent axle and cylinders, yet, at present common diesel engine box body adopts integrally casting moulding, it exists following not enough: (1) integrated type casing adopts general casting method, be that molten metal relies on self gravitation to flow into die cavity, then solidifying, and adopt the casing that general casting method obtains easily to shrink distortion, will affect the installation of other component like this, meanwhile, adopt general casting method also to there is the shortcomings such as manufacturing efficiency is low; (2), when the component in casing are damaged, because casing can not be dismantled, therefore inconvenience is keeped in repair broken parts, needs integral body to change; (3) machining time location and clamping difficulty are high, are unfavorable for guaranteeing machining precision.
Model utility content
The purpose of this utility model is to solve that integrated type casing exists easily shrinks the shortcomings such as distortion, manufacturing efficiency are low, inconvenient maintenance, and a kind of split type diesel engine box body is provided.
The utility model has adopted following technological scheme:
A kind of split type diesel engine box body, comprise casing, on described casing, have for the crankshaft installed hole of bent axle being installed and for the mounting hole of cylinder sleeve of cylinder sleeve is installed, described casing is assembled by left box body and right case, described left box body and right case adopt die cast, and described mounting hole of cylinder sleeve forms when described left box body and right case assembling.
Further, be provided with the threaded connection hole of mutual correspondence on described left box body and right case, left box body and right case connect into integral body by threaded connector.
Further, be provided with for the cushion block of oil pump is installed on described left box body, described cushion block and left box body are one-body molded.
Further, be provided with the bearing support for coordinating with bent axle on described right case, described bearing support and right case are one-body molded.
Remarkable result of the present utility model is:
(1) casing is assembled by left box body and right case two-part, left box body and right case adopt die cast, compare with general casting method, and die cast contributes to reduce the shrinkage of casing, guarantee the installation precision of component, can also enhance productivity simultaneously;
(2) when the component in casing are damaged, left box body and right case can be taken apart, the broken parts in casing is keeped in repair, with regard to not needing integral body to change, reduce maintenance cost like this;
(3) left box body and right case are processed separately, and when machining, the difficulty of location and clamping reduces, and is more conducive to guarantee machining precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of left box body in the utility model;
Fig. 2 is the structural representation of right case in the utility model;
Fig. 3 is the assembly structure schematic diagram of the utility model left box body and right case;
Fig. 4 is the rear view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 to Fig. 4, a kind of split type diesel engine box body, comprise casing 1, on casing 1, have for the crankshaft installed hole 11 of bent axle being installed and for the mounting hole of cylinder sleeve 12 of cylinder sleeve is installed, casing 1 is assembled by left box body 1a and right case 1b, left box body 1a and right case 1b adopt die cast, and mounting hole of cylinder sleeve 12 forms when left box body 1a and right case 1b assembling.The utility model is usingd the center line (actual is exactly the center line of cylinder) of mounting hole of cylinder sleeve 12 as joint line, casing 1 is divided into left box body 1a and right case 1b, again left box body 1a and right case 1b are passed through to die cast, not only reduced the shrinkage of casing 1, guarantee the installation precision of parts and components of diesel engine, but also improved manufacturing efficiency; Meanwhile, because casing 1 is divided into left box body 1a and right case 1b, therefore, when carrying out machining, the location of left box body 1a and right case 1b and clamping difficulty reduce, and are more conducive to guarantee machining accuracy.
On left box body 1a and right case 1b, be provided with many groups threaded connection hole 13 of correspondence mutually, left box body 1a and right case 1b connect into integral body by threaded connector (as bolt, stud etc.), because adopting threaded connector, left box body 1a and right case 1b be connected, therefore both are convenient to dismounting, when the component in casing 1 are damaged, can easily casing 1 be taken apart broken parts is keeped in repair.
On left box body 1a, be provided with for the cushion block 15 of oil pump is installed, cushion block 15 is one-body molded with left box body 1a.Conventionally, the crude oil pump cushion block of diesel engine is to be fixed on casing 1 by links such as bolts, and cushion block 15 of the present utility model is one-body molded with left box body 1a, with regard to not needing, separately cushion block 15 is installed and fixed like this, need on left box body 1a, not process and be used for the fixedly attachment hole of cushion block 15, be conducive to improve the manufacturing efficiency of diesel engine yet.
On right case 1b, be provided with the bearing support 14 for coordinating with bent axle, bearing support 14 is one-body molded with right case 1b.Conventionally, the crankshaft bearing seat of diesel engine is after casing 1 has been cast, then is fixedly installed on casing 1, and bearing support of the present utility model 14 is one-body molded with right case 1b, so just do not need again independent installation shaft bearing 14, be conducive to improve the manufacturing efficiency of diesel engine.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although claimant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
