Description
技术领域technical field
本实用新型属于车辆发动机零部件，具体涉及一种发动机气缸盖。The utility model belongs to vehicle engine components, in particular to an engine cylinder head.
背景技术Background technique
目前国内外开发的发动机普遍采用单缸四气门、双顶置凸轮轴气缸盖，此类气缸盖都采用挺柱孔悬空结构，即挺柱孔板1与气缸盖体内地面2之间润滑油间隙3(如图1所示)；以方便润滑油从凸轮轴径流回到发动机油底壳。此类结构的气缸盖的缺点是：铸造气缸盖时由于液态金属需要较长的路径才能流到挺柱孔悬空结构处，所以挺柱孔悬空结构处的金属致密度不够，容易产生缩孔等铸造缺陷，挺柱孔悬空结构处的强度也受到影响；机加气缸盖时由于挺柱孔结构的底部是悬空的，所以机加挺柱孔过程中此处容易产生应力变形，导致机加废品率上升，需要耗费大量的人力和物力；在发动机实际工作过程中，挺柱孔悬空结构由于受到周期性的侧向力作用，更容易发生应力变形。At present, engines developed at home and abroad generally use single-cylinder four-valve, double overhead camshaft cylinder heads. This type of cylinder head adopts a tappet hole suspension structure, that is, the lubricating oil gap between the tappet orifice plate 1 and the ground 2 in the cylinder head body. 3 (as shown in Figure 1); to facilitate the lubricating oil runoff from the camshaft back to the engine oil pan. The disadvantage of the cylinder head with this structure is: when casting the cylinder head, since the liquid metal needs a long path to flow to the suspended structure of the tappet hole, the metal density at the suspended structure of the tappet hole is not enough, and shrinkage cavities are prone to occur. Casting defects, the strength of the suspended structure of the tappet hole is also affected; when the cylinder head is machined, because the bottom of the tappet hole structure is suspended, stress deformation is easily generated here during the process of machining the tappet hole, resulting in machining waste In order to increase the efficiency, it needs a lot of manpower and material resources; in the actual working process of the engine, the suspension structure of the tappet hole is more prone to stress deformation due to the periodic lateral force.
发明内容Contents of the invention
本实用新型的目的在于提供一种具有可靠的挺柱孔支撑结构的发动机气缸盖，以解决上述问题。The purpose of this utility model is to provide an engine cylinder head with a reliable tappet hole support structure to solve the above problems.
本实用新型的技术方案为：具有可靠的挺柱孔支撑结构的发动机气缸盖，它包括发气缸盖体，气缸盖体上设有挺柱孔板，挺柱孔板上设有挺柱孔，挺柱孔板与气缸盖体内地面之间润滑油间隙，挺柱孔板与气缸盖体内地面之间还设有支撑筋板。The technical scheme of the utility model is: an engine cylinder head with a reliable tappet hole support structure, which includes a cylinder head body, a tappet hole plate is provided on the cylinder head body, a tappet hole is provided on the tappet hole plate, There is a lubricating oil gap between the tappet orifice plate and the ground in the cylinder head body, and a supporting rib is also provided between the tappet orifice plate and the ground in the cylinder head body.
所述支撑筋板设在位于相邻的两个挺柱孔之间的挺柱孔板与气缸盖体内地面之间。The supporting ribs are arranged between the tappet orifice plate between two adjacent tappet holes and the ground in the cylinder head body.
在挺柱孔板与气缸盖体内地面之间还设有支撑筋板，气缸盖的铸造工艺和机加工艺都得到很大改善，发动机实际运行过程也更可靠。There is also a supporting rib plate between the tappet orifice plate and the ground in the cylinder head body, the casting process and machining process of the cylinder head have been greatly improved, and the actual operation process of the engine is also more reliable.

具体实施方式Detailed ways
如图2、3所示，发气缸盖体3的上的挺柱孔板4上设有挺柱孔5，在位于相邻的两个挺柱孔5之间的挺柱孔板与气缸盖体内地面之间设有支撑筋板6。本实施例中，由于气缸盖上有十六个挺柱孔，所以每两个挺柱孔下方增加一个支撑筋的话共需要增加8个支撑筋。As shown in Figures 2 and 3, the tappet orifice 4 on the cylinder head body 3 is provided with a tappet hole 5, and the tappet orifice and the cylinder head between two adjacent tappet holes 5 Support ribs 6 are arranged between the ground in the body. In this embodiment, since there are sixteen tappet holes on the cylinder head, if one support rib is added below every two tappet holes, a total of 8 support ribs need to be added.
增加了8个支撑筋后，气缸盖的铸造工艺和机加工艺都得到很大改善，发动机实际运行过程也更可靠。可依据本适用新型的技术方案，根据气缸盖的具体结构来设计支撑筋的外形和数量。After the addition of 8 support ribs, the casting process and machining process of the cylinder head have been greatly improved, and the actual operation of the engine is also more reliable. The shape and quantity of the support ribs can be designed according to the specific structure of the cylinder head according to the technical scheme of the applicable model.
