Description

一种用于管路数字化定角向的方法 A method of digital line for a given angular

技术领域 FIELD

[0001] 本发明涉及导管类零件制造技术领域,具体涉及一种用于管路数字化定角向的方法。 [0001] The present invention relates to a catheter-based parts manufacturing technical field, particularly relates to a method for digital line to a predetermined angle.

背景技术 Background technique

[0002] 航空发动机上有大量的导管类零件,其中涉及的零件号众多但同一件号大多只使用一件,因此,同型号的导管类零件加工特点为"规格多、批量小"。 [0002] There are a lot of aero-engine duct-type parts, part numbers involved are numerous, but with a number of mostly use only one, therefore, conduit parts processing characteristics of the same model as "specifications, in small quantities." 导管类零件由于其功能特性,不同件号其形状和结构复杂,粗细各异,长短各异,同台发动机上不存在管型相同的两个零件,各导管因其相应的装配关系,其管型走向及接头空间角向均存在差异,因此,长久以来发动机导管零件设计图中只规定了配套关系,并未对管型、角向等具体信息进行规定,具体零件的加工也一直依赖于现场取样、装配。 Parts catheter because of its functional properties, different part numbers and configurations of complex shape, different thickness, different length, the same two tubular parts do not exist on the same engine, because each duct assembly corresponding relationship, which tube type and joint space towards the corner differences are, therefore, has long been part of the catheter design drawing engine only provides complementary relationship, not the specific information casts, angular, etc. regulations, specific parts of the process have been dependent on the scene sampling assembly.

[0003] 但随着制造业技术水平及加工条件的不断提高,原始的加工技术就越显繁琐,流程臃肿且存在严重的资源浪费。 [0003] However, with the continuous improvement of manufacturing technology and processing conditions, the original processing technology more significant tedious, cumbersome process and there is a serious waste of resources.

[0004] 具体的不足分析如下: [0004] Specific deficiencies as follows:

[0005] (1)对于加工条件有严格的要求:整个确定管路走向及接头角向的工作必须在整机装配现场进行,并且整机已基本装配完毕或已装配到具有取样条件的状态。 [0005] (1) The processing conditions are strict requirements: the entire pipeline to determine the joint angle and the work must be done in the machine assembly site, and the machine has substantially assembled or assembled to a state with a sampling condition.

[0006] (2)周期长:由于其苛刻的加工条件要求,则导管类零件的加工必须在整机已基本装配完毕后方可进行,因此,导管类零件预计的加工周期中,有近1/2的时间浪费在等待中。 [0006] (2) Long period: because of its severe processing conditions required, the parts of the process as a catheter must be carried out only after the machine has been substantially assembled, therefore, is expected as a catheter part machining cycle, nearly 1 / 2 time wasted in waiting. 即便加工条件具备,整个取样过程则全部依赖于钳工手工制造,并且需要经历反复的校正工作方能完成取样。 Even if the processing conditions are met, the entire sampling process are all dependent on the fitter handmade, and the correction operation needs to undergo repeated in order to complete the sampling. 最终,再依赖取好的样件加工零件成品。 Finally, again dependent take a good sample processing finished part. 整个加工过程中存在过多的等待和重复,周期庸长。 Throughout the process and the presence of excessive waiting repetition, Yong long period.

[0007] (3)加工稳定性及一致性差:由于加工条件的限制,取样质量的好坏主要依赖以下两点:①所用于取样的整机装配的质量;②操作取样的钳工的操作技能。 [0007] (3) processing stability and poor consistency: due to the limitation of processing conditions, their quality depends sampling following two points: ① mass of the machine assembly for sampling; ②-samples fitter skills. 任何一点出了问题就会导致样件的反复校正、返修。 Any bit of a problem can lead to repeated calibration sample, and repair. 再者,由于整个取样过程为手工操作,没用对应的数据支持,随意性过大,再现性和一致性均无法保证,以上问题均为导管零件后期的使用埋下了隐患。 Furthermore, because the entire sampling process for manual operation, useless corresponding data support, randomness is too large, reproducibility and consistency is not guaranteed, the above problems are the use of the latter part of the catheter potential problems.

[0008] 随着UG建模技术在航空制造领域的飞速发展,及生产设备加工能力的逐步完善, 仅借助导管类零件的UG设计图,就可以确定导管零件的管型走向,并轻松的加工出单根管件,但其上所配套接头角向的确定中能依靠现场试装取样,或利用对应的装配夹具确定,使得整个加工流程中的不足并未因为管型走向的轻松确定而得到改善。 [0008] With the rapid development of UG modeling techniques in the field of aviation manufacturing, and gradually improve the production equipment and processing capacity, and only via a catheter Parts of UG design, we can determine the part of the catheter tube to, and easy processing a single tube, but it is determined on the supporting joint angular field of test equipment can rely on sampling, or determined by the corresponding fitting jig, so that insufficient throughout the machining process is not as easy to determine the obtained tubular improve.

具体实施方式 detailed description

[0039] 下面结合附图对本发明进行详细说明。 DRAWINGS The invention is described in detail [0039] below in conjunction.

[0040] 假设带有空间角向接头的导管已正确装配,并假设管端的接头是导管的一个弯曲段。 [0040] The hypothesis has been assembled with the spatial angle to a pipe joint, the pipe end fitting and assuming the catheter is a curved section.

[0041] 1)利用UG软件获取辅助模型空间数据: [0041] 1) using UG software acquisition assistance data model space:

[0042] 参见图2和图3,从UG设计图中可以捕捉出需加工管组件各段中心线的交点坐标, 其中包括接头转角处的交点坐标和接头端面中心点的坐标,具体得到端面中6、配套位置中心7、第一管子两轴线交点8、第二管子两轴线交点9的坐标。 [0042] Referring to FIGS. 2 and 3, the UG may capture the design coordinates of each intersection of the centerline segments to be processed tube assembly, including the coordinates of the center point of the intersection point coordinates and the end face of the joint at the corner joints, in particular to give the end faces 6, 7 supporting the position of the center of the intersection point 8, the coordinates of the intersection of the two axes 9 of the two axis of the second tube of the first tube.

[0043] 捕捉点坐标的原则:由于两条相交的直线可以确定一个平面,且此次捕捉点的目的是用于确定接头与管子的空间角向关系,因此,在空间上仅需两个相交的平面即可达到预期效果。 [0043] The principle of capturing coordinates: As two straight lines intersecting a plane can be determined, and the object of the capture point for the pipe joint to determine the spatial angular relationship, therefore, only two spatially intersect the plane can achieve the desired results. 于是可忽略无需参与的导管其它弯曲段,仅需与接头段(模型中假设为一个导管弯曲段)及与接头相邻一个导管弯曲段。 Thus negligible catheter without the involvement of other curved section, only the joint section (the model assumed a curved conduit section) adjacent to the joint, and a curved section of the catheter. 因此,此类有关接头角向的任何模型均可简化为2个弯曲段的导管模型。 Thus, any such model may be related to the angle of the joint is simplified model of two bent conduit sections.

[0044] 2)利用UG软件建立辅助模型: [0044] 2) establish auxiliary model using UG software:

[0045] 使用UG软件中的"机械管线布置"功能,将在步骤1)中所捕捉的坐标点输入,得到一个将接头假设为一段弯管的纯导管视图,即得到UG建模。 [0045] The use UG software "mechanical arrangement pipeline" function, in step 1) the captured input coordinate points, to obtain a pure hypothesis catheter connector section view of the elbow, i.e., to obtain UG modeling.

[0046] 2. 1)选取一根总长为150mm,直径为Φ10的导管组件,直线度、圆度、端面与轴线垂直度均不大于0. 1,管端无毛刺。 [0046] 2.1) Select a total length of 150mm, a diameter of Φ10 catheter assembly, straightness, roundness, perpendicularity of the axis of the end face of not greater than 0.1, burr-free tube end.

[0047] 2. 2)使用UG软件对该组件对应的UG建模图形进行取点,具体数据见下表1 : [0047] 2.2) using UG software take of the UG pattern model corresponding to the assembly, particularly the data in Table 1 below:

[0048] 具体捕捉点位置见图2。 [0048] DETAILED capturing position shown in Figure 2.

[0049] 表1管组件UG图捕捉点数据(单位:mm) [0049] Table 1 Component UG FIG capture the points (unit: mm)

[0050] [0050]

Figure CN105345382AD00061

[0051] 在此,可以进一步简化模型,由于两条相交的直线可以确定一个平面,且此次建模目的是位确定接头与管子的空间角向关系,因此,在空间上仅需两个相交的平面即可达到预期效果。 [0051] Here, the model can be further simplified, since the two straight lines intersecting a plane can be determined, and the determined model object sterically joint angular relationship with the tube, and therefore, only two spatially intersect the plane can achieve the desired results. 于是此模型可忽略无需参与的导管其它弯曲段,仅需与接头段(模型中假设为一个导管弯曲段)及与接头相邻一个导管弯曲段。 Thus this model without the involvement of the catheter negligible other curved section, only the joint section (assuming a curved conduit section model) and the joint curved section adjacent a conduit. 因此,此类有关接头角向的任何模型均可简化为2个弯曲段的导管模型。 Thus, any such model may be related to the angle of the joint is simplified model of two bent conduit sections.
