内容提要
此次毕业设计任务是针对2108发动机机体通主油道双向斜油孔的设计,在设计专用夹具时为了能满足工件的加工精度要求,需要考虑合理的定位方案、合适的尺寸、公差和技术要求,并进行必要的精度分析。
在发动机机体上,通常两侧均匀布置有主油道孔,机油泵泵出的润滑油经机油滤清器后从主油道沿着位于每一道主轴承隔壁中的横油道流到曲轴主轴承中,从主油道通曲轴主轴承处的斜油道位于主轴承隔臂墙中,隔臂墙比较薄,而斜油孔有属于深孔,这样,加工十分困难。对于这种斜深孔加工,常用的加工方法是在摇臂钻床上,设计一钻床夹具,工件在夹具上定位采用一面两销,机体在夹具中斜向放置。这种加工缺陷是工件定位不是很稳定,对销产生的压力很大,销容易变形;且利用摇臂钻床加工,生产效率不高。为此在分析发动机机体双向斜油孔加工工艺的基础上,设计加工此斜油孔的组合机床夹具。
本课题设计的组合机床夹具采用了支架式结构,夹具主要由三部分组成:夹具底座、夹具支架和夹具上座。夹具底座支承夹具支架和夹具上座,夹紧机构放置在夹具底座内;夹具上座,夹具底座和夹具支架组成的空间放置工件,工件通过滚道推入定位空间;定位销,支撑板,钻套及控制定位销升缩的机构等部件安装在夹具上座中。
根据柴油机的设计与加工要求,机体加工过程中,大部分工序都是以一面两销定位,故加工主油道双向斜油孔,采用以机体底面和底面上相距240 0.01mm的两个直径为16mm的工艺孔进行定位,限制六个自由度,实现基准统一和基准重合原则。定位销的伸缩可由液压系统控制。考虑到工件的质量较大,手动夹紧难以实现,故采用液压系统驱动、斜楔夹紧机构。
Summary
2108 engine block is the graduation design task for the main vittae two-way oblique oil hole design, in the design of special fixture in order to meet the workpiece when machining precision requirement, need to consider the reasonable positioning scheme, the right dimensions, tolerances, and technical requirements, and make the necessary accuracy analysis.
On engine body, usually on both sides of the uniform arrangement are the main oil passage hole, oil pump pumping the oil after the oil filter from the main oil passage along the located next door to each main bearing the cross flow into the crankshaft main bearing oil, from the main oil passage through the crankshaft main bearing of oblique oil duct is located in the main bearing arm of the wall insulation, lie between arm wall is thin, and oblique oil hole has belongs to deep hole, so that processing is difficult. For this kind of inclined deep hole processing, common processing method is on the radial drilling machine, a drill jig design, the workpiece on the fixture positioning using a two pin, the body placed diagonally in the jig. This kind of defect is workpieces position is not very stable, counter pressure is very big, pin easy to deformation; And the use of radial drilling machine processing, the production efficiency is not high. This two-way oblique oil hole processing technology on the analysis of the engine block, on the basis of designing the inclined oil hole modular machine tool fixture.
This topic design of modular machine tool fixture used the scaffolding structure, the fixture is mainly composed of three parts: clamp, clamp bracket and base seat base. Jig base supporting clamp bracket and the seat base, fastening device placed on the jig base inside; Clamp table and the base and the clamp bracket of space to place the workpiece, the workpiece through the raceway position into the space; Positioning pin, support plate, drill sets and control the positioning pin up institutions components installed in a fixture in attendance.
According to the design and processing requi ..
