Description

一种压配装置及阀装配系统 技术领域
本发明涉及自动化检测与装配技术领域，特别是指一种压配装置及阀装配系统。
背景技术
常开阀、常闭阀等阀类功能部件在进行装配时，经常会需要压配工序将两工件压配在一起形成压紧配合，同时要求满足一定的装配精度要求。例如图1所示的增压阀，需要将阀座和阀体压配在一起，使得推杆在克服弹簧力的作用下，凸出阀体上端面的距离为A±0.015(A为客户指定尺寸)。
但是，使用现有的压配装置对阀座与阀体进行压配时，在压配的过程中，力量需要达到大于1000牛顿才可以完成。如果力量过大或者力量过小，就会出现压配不到位，凸出阀体上端面的距离超出精度要求的情况。由此，会造成超出工件的报废。因此，亟需一种压配装置，以能够在压配时对两工件的位置进行检测及控制，以使压配后的工件满足精度要求。
发明内容
有鉴于此，本发明的主要目的在于提供一种压配装置及阀装配系统，以能够在压配时对两工件的位置进行检测及控制，以使压配后的工件满足精度要求。
本发明第一方面提供一种压配装置，用于将第一配件与第二配件压配连接，并使所述第一配件中的第三配件与所述第二配件抵接后，所述第三配件的上端面与所述第一配件的上端面之间相距预定尺寸，包括：支架；压头，所述压头包括固定部与主体部，所述主体部与所述固定部滑动连接；支撑座，用于支撑承载所述第一配件、所述第二配件与第三配件的定位工装；第一下压机构，包括活动板，所述活动板与所述支架滑动连接，所述压头的所述固定部固定在所述活动板上与所述支撑座相对应位置，所述第一下压机构设置在所述支架上，通过使所述活动板相对于所述支架滑动从而驱动所述压头的所述主体部沿压配方向对所述第一配件与所述第二配件进行第一压配；检测机构，所述检测机构设置在所述压头的所述主体部上，所述检测机构具有探针，所述压头的所述主体部的下端具有检测口，所述探针由所述检测口伸出，用于对所述第一压配后所述第一配件上端面与所述第三配件上端面之间的距离进行检测，获取第一检测结果；第二下压机构，所述第二下压机构设置在所述支架上，根据所述第一检测结果驱动所述压头的所述主体部相对于所述固定部滑动从而沿所述压配方向对所述第一配件与所述第二配件进行第二压配，所述检测机构还用于在第二压配时对所述第一配件上端面与所述第三配件上端面之间的距离进行检测，获取第二检测结果；所述第二下压机构根据所述第二检测结果进行所述第二压配，在进行所述第一压配与所述第二压配时，所述压头的所述主体部的下端面接触所述第一配件的上端面，所述探针接触所述第三配件的上端面。
由此，可以将对第一配件与第二配件的精压压配分解为第一压配与第二压配，在第一压配完成后，通过对第一配件与第二配件之间的位置进行检测，可以确定第一配件与第二配件之间的位置，从而可以对第二压配进行调整，以使第二压配后第一配件与第二配件之间的位置能够满足精度要求。
本申请中采用两套下压机构，第一下压机构通过活动板的移动带动整个压头压住第一配件，同时检测机构执行检测，然后第二下压机构根据该检测结果使压头中的主体部相对于固定部滑动，下压第一配件，同时，检测机构继续检测，以实时控制第二下压机构的动作。由此，能够先由第一下压机构压住第一配件，然后在此状态下进行检测并由第二下压机构进行压配。也就是说，在第一下压机构压住、扶稳第一配件并使压头的主体部的下端面与第一配件的上端面紧密接触的状态下，检测机构进行检测、第二下压机构进行压配，由此可以提高检测精度，提高压配精度。
另外，通过将检测机构设置在压头的主体部上，检测机构的探针由压头的主体部下端的检测口伸出，压头的主体部的下端面接触第一配件的上端面，探针接触第三配件的上端面，从而可以直接对第一配件和第三配件的上端面之间的距离进行检测，以提高检测精度。通过将探针装在压头上，在第一压配和第二压配中，压头下压的同时由探针执行检测，从而能够提高作业效率。
作为第一方面一种可能的实现方式，所述第一下压机构包括：下压气缸，所述下压气缸设置在所述支架上，所述下压气缸具有沿所述压配方向设置的第一驱动杆，所述第一驱动杆与所述活动板固定连接。
作为第一方面一种可能的实现方式，所述压头包括：限位部，所述限位部设置在所述主体部上，所述第一压配时所述固定部与所述限位部相抵接。
作为第一方面一种可能的实现方式，所述主体部具有中空的腔室，所述腔室朝向所述支撑座一侧设置有检测口；所述检测机构包括：测芯，所述测芯设置在所述腔室内，可以沿所述压配的方向移动，所述测芯具有探针，所述探针可以由所述检测口伸出；传感器，所述传感器设置在所述腔室内，用于检测所述测芯的位移。
作为第一方面一种可能的实现方式，所述检测口的尺寸大于所述第三配件。
作为第一方面一种可能的实现方式，所述第二下压机构包括伺服电动缸，所述伺服电动缸设置在所述支架上，所述伺服电动缸在与所述主体部相对应的位置，具有沿所述压配方向设置的第二驱动杆；所述伺服电动缸与所述支撑座沿所述压配方向分别位于所述压头的两侧。
可选的，在压头的主体部上设置有锥形块，锥形块与主体部的轴心相同，锥形块的上部尺寸大下部尺寸小，在压头的固定部上设置有与所述锥形块相适配的锥形孔。由此，通过锥形块和锥形孔的配合，可以对主体部进行扶正，避免压配的过程中发生歪斜，可以在第一压配时使压头的主体部的下端与第一配件的上端面间的接触为“压实”状态，以提高主体部对第一配件、第二配件进行压配时的检测与压配精度。
本发明第二方面提供一种阀装配系统，包括第一方面任意一种压配装置。
由此，使用本申请中的阀装配系统，可以通过压配装置将对第一配件与第二配件的精压压配分解为第一压配与第二压配，在第一压配完成后，通过对第一配件与第二配件之间的位置进行检测，可以确定第一配件与第二配件之间的位置，从而可以对第 二压配进行调整，以使第二压配后第一配件与第二配件之间的位置能够满足精度要求。通过采用两套下压机构，第一下压机构通过活动板的移动带动整个压头压住第一配件，同时检测机构执行检测，然后第二下压机构根据该检测结果使压头中的主体部相对于固定部滑动，下压第一配件，同时，检测机构继续检测，以实时控制第二下压机构的动作。由此，能够先由第一下压机构压住第一配件，然后在此状态下进行检测并由第二下压机构进行压配。也就是说，在第一下压机构压住、扶稳第一配件并使压头的主体部的下端面与第一配件的上端面紧密接触的状态下，检测机构进行检测、第二下压机构进行压配，由此可以提高检测精度，提高压配精度。另外，通过将检测机构设置在压头的主体部上，检测机构的探针由压头的主体部下端的检测口伸出，压头的主体部的下端面接触第一配件的上端面，探针接触第三配件的上端面，从而可以直接对第一配件和第三配件的上端面之间的距离进行检测，以提高检测精度。通过将探针装在压头上，在第一压配和第二压配中，压头下压的同时由探针执行检测，从而能够提高作业效率。

具体实施方式
下面，结合附图，对本申请实施例中的阀装配系统的具体结构进行详细的描述。
图1为一种增压阀100的轴向剖面图，以增压阀100为例，对本申请实施例中的阀装配系统的压配对象进行示例性的说明。如图1所示，增压阀100包括：阀体110、阀座120、推杆130、弹簧140、动铁150、外壳160等配件。
其中，阀体110呈圆筒状，阀座120、弹簧140以及推杆130安装在阀体110内部。阀座120呈一端设置底部另一端设置开口的杯状结构，并在阀座120的底部轴心位置设置有圆形通孔状的阀口121。安装时，阀座120设置有阀口121的一端需要由阀体110的一端压配安装在阀体110内，使阀座120与阀体110通过过盈配合实现固定连接。安装后，阀座120的一端位于阀体110内部，阀座120的另一端由阀体110的端部露出。弹簧140与推杆130由阀体110的另一端放入阀体110内部，弹簧140套设在推杆130一端的外周面上，推杆130的另一端由阀体110的端部露出。弹簧140的一端与推杆130抵接，另一端与阀座120抵接，弹簧140通过自身的弹力可以使推杆130与阀座120分离。
外壳160呈一端封闭一端开口的圆形杯状结构，动铁150设置在外壳160内，与外壳160内部的形状相适配。外壳160的开口一端套设在阀体110的另一端，可以通过压配或者焊接等方式与阀体110固定连接。外壳160与阀体110安装完成后，动铁150与推杆130的另一端相抵接，动铁150在外壳160内沿轴心方向移动，可以推动推杆130压缩弹簧140，使推杆130的一端与阀口121相抵接，从而控制阀口121的打开与关闭。
另外，根据工艺要求，阀体110与阀座120压配连接后，推杆130在压缩弹簧，使推杆130的一端与阀口121抵接后，要求推杆130的另一端由阀体110的端面凸出的距离处于预定装配精度范围内。
图2为本申请实施例中增压阀100的装配步骤示意图。如图2所示，增压阀100的装配步骤可以包括：
步骤S101、上料。
通过上料装置按照预定的顺序将阀体110、阀座120、推杆130、弹簧140、动铁150、外壳160等部件放置到预定位置。
步骤S102、压配。
在上料装置将阀体110、阀座120、推杆130、弹簧140、动铁150、外壳160中 的预定部件放置在预定的位置后，通过压配装置进行压配，从而将例如阀体110与阀座120之间和/或阀体110与外壳160之间实现过盈配合，同时保证阀体110与阀座120之间和/或阀体110与外壳160之间的配合处于预定装配精度范围内。
步骤S103、检测。
在增压阀100的装配过程中和/或装配完成后，对增压阀100完成装配的配件之间的位置或气密性等项目进行检测，从而保障了增压阀100的产品质量。
下面，以增压阀100为例，结合增压阀100的装配步骤，对本申请实施例中的阀装配系统进行详细的说明。
图3为本申请实施例中阀装配系统的分布示意图之一；图4为图3中阀装配系统的前侧投影示意图。如图3、图4所示，该阀装配系统包括：第一转盘装置200、第二转盘装置300以及第三转盘装置400，第一上料装置(即阀座上料装置500与阀体上料装置600)、第二上料装置(即弹簧上料装置1100与推杆上料装置1200)以及第三上料装置(即外壳与动铁上料装置1700)，第一移料装置900、第二移料装置1500与第三移料装置1900，以及围绕第一转盘装置200、第二转盘装置300或者第三转盘装置400设置的压配装置A700、压配装置B1300、压配装置C1800或者其他用于增压阀100装配的装置，上述装置可以设置在工作台或其他合适的设备上。
如图3所示，第一转盘装置200、第二转盘装置300与第三转盘装置400呈线性排列，用于将配件在不同的加工工位间输送。第一上料装置、第二上料装置与第三上料装置设置在第一转盘装置200、第二转盘装置300与第三转盘装置400的一侧位置，分别用于向第一转盘装置200、第二转盘装置300与第三转盘装置400上放置配件。第一移料装置900设置在第一转盘装置200、第二转盘装置300与第三转盘装置400的另一侧位置，用于将第一转盘装置200上装配后的配件转移到第二转盘装置300。第二移料装置1500设置在第一转盘装置200、第二转盘装置300与第三转盘装置400的另一侧位置，用于将第二转盘装置300上装配后的配件转移到第三转盘装置400。
如图3、图4所示，第一转盘装置200包括：转动盘210、定位工装220以及安装座230。其中，转动盘210呈圆盘状或圆环状，设置在安装座230上。转动盘210与安装座230的轴心重合，安装座的顶部处于露出状态，可以用于安装例如下述阀体上料机构620等设备。转动盘210上靠近边缘位置可以设置有多个用于放置、固定配件的定位工装220，例如可以沿转动盘210的边缘均匀设置6个定位工装220，相邻两个定位工装220之间相差60°角。

如图3所示，本申请实施例中的阀座上料装置500包括振动送料机构510与阀座吹料机构520。其中，阀座吹料机构520可以将振动送料机构510提供的阀座120，吹送到位于阀座上料工位的定位工装220上。阀座120放置完成后，转动盘210旋转60°，将阀座120输送到下一工位。
如图3所示，本申请实施例中的阀体上料装置600可以包括：振动送料机构610 与阀体上料机构620。阀体上料机构620可以通过机械爪将振动送料机构610提供的阀体110夹取后，放置到位于阀体上料工位的阀座120上，从而完成阀体110的上料。
如图3所示，在阀座压配工位A相应位置设置有压配装置A700，压配装置A700可以对定位工装220上的阀体110与阀座120进行压配，即将阀座120的一部分压入阀体110内，保证阀座120与阀体110处于连接状态，避免阀座120与阀体110在转移时发生位移，影响压配的精度。
如图3围绕转动盘210的外侧边缘的工位还可以包括分别位于阀座上料工位、阀体上料工位以及阀座压配工位A的下一工位的第一检测工位。第一检测工位上根据检测目标的不同，还可以设置有相应检测功能的第一检测装置800，以确保上料及压配符合预定装配标准。
阀座120与阀体110在第一转盘装置200上完成预定装配工序后，由第一转盘装置200输送到下料工位，由第一移料装置900将阀座120与阀体110转移到第二转盘装置300上。

第一移料装置900可以将第一转盘装置200上完成预定装配的阀座120与阀体110放置在第二转盘装置300上料工位的定位工装320上，从而完成上料。然后，转动盘310转动，将阀座120与阀体110输送到下一工位。
如图3所示，弹簧上料装置1100包括振动送料机构1110以及弹簧吹料机构1120。弹簧吹料机构1120设置在弹簧上料工位的定位工装320的相应位置。振动送料机构1110提供的弹簧140，由弹簧吹料机构1120输送到位于弹簧上料工位的定位工装320上。

如图3所示，围绕转动盘310的外侧边缘的工位还可以包括位于弹簧上料工位与推杆上料工位之后的第二检测工位。第二检测工位上设置有第二检测装置1400，以对弹簧140与推杆130的放置位置进行检测。检测完成后，转动盘310转动，将阀座120、阀体110弹簧140与推杆130输送到下一工位。
如图3所示，在压配工位B设置有压配装置B1300。压配装置B1300可以对压配工位B的定位工装320中的阀座120(即第一配件)与阀体110(即第二配件)进行压配，使推杆130(即第三配件)的一端与阀口121抵接后，推杆130的另一端由阀体110的端面凸出的距离处于预定距离。
图5为本申请实施例中压配装置B1300的结构示意图，示出了压配装置B1300的一种可能的实现形式。如图5所示，本申请实施例中的压配装置B1300包括：支架 1310、压头1320、支撑座1330、第一下压机构1340、第二下压机构1350以及检测机构1360。其中，压头1320设置在第一下压机构1340上与压配工位B的定位工装320相对应的位置，第一下压机构1340设置在支架1310上，驱动压头1320沿压配方向(阀体110与阀座120压配连接时的位移方向)对定位工装320上的阀座120与阀体110进行第一压配。检测机构1360设置在压头1320上，用于对第一压配后阀座120与阀体110之间的位置进行检测，获取第一检测结果。第二下压机构1350设置在支架1310上，根据第一检测结果驱动压头1320沿压配方向对阀座120与阀体110进行第二压配。由此，可以将对阀座120与阀体110的压配分解为第一压配与第二压配，在第一压配完成后，通过对阀座120与阀体110之间的位置进行检测，可以确定阀座120与阀体110之间的位置，从而可以对第二压配进行调整，以使第二压配后阀座120与阀体110之间的位置能够满足精度要求。
图6为图5中压配装置B1300的局部剖视图。如图5、图6所示，支架1310包括位于上部水平设置的顶板1311，位于底部的底板1312，以及设置在顶板1311与底板1312之间，分别位于两侧竖直设置的立轴1313，顶板1311、底板1312通过立轴1313固定连接，形成方形框架结构。支撑座1330设置在底板1312上，位于压配工位B相应位置，以对位于压配工位B的定位工装320提供支撑，从而在第一压配与第二压配时，提高定位工装320的稳定性。
第一下压机构1340包括活动板1341以及下压气缸1342，活动板1341水平设置在顶板1311与底板1312之间，活动板1341的两端分别与两立轴1313滑动连接。下压气缸1342设置在顶板1311的底部，下压气缸1342具有垂直向下设置的第一驱动杆1342a，第一驱动杆1342a的端部与活动板1341连接，可以驱动活动板1341沿立轴1313上下移动。
第二下压机构1350包括电动缸1351，电动缸1351设置在顶板1311的上表面，具有穿过顶板1311垂直向下伸出的第二驱动杆1351a，电动缸1351可以控制第二驱动杆1351a向下伸出或向上收回。
图7为图5中压头1320部分的局部放大图。如图7所示，压头1320包括主体部1321与固定部1322。其中，主体部1321整体呈柱状结构，主体部1321穿过固定部1322与固定部1322滑动连接。固定部1322位于主体部1321的中间区域，主体部1321通过固定部1322固定安装在活动板1341的中间位置，使主体部1321处于压配工位B上的定位工装320的正上方。主体部1321上各部分之间的直径并不相同，从而在主体部1321靠近下端位置，在两直径不同的位置形成限位部1323。限位部1323与固定部1322相抵接，使得活动板1341带动压头1320向下移动时，通过限位部1323使压头1320的主体部1321与活动板1341相对固定。同时，主体部1321上还可以设置与主体部1321同轴心的锥形块，锥形块呈上部尺寸大，下部尺寸小的状态设置。固定部1322内在与该锥形块相应位置设置有锥形孔，锥形孔与锥形块相适配，同样设置成上部尺寸大，下部尺寸小的状态。由此，通过锥形块与锥形孔之间的配合，固定部1322还可以对主体部1321起到扶正的作用，以使主体部1321可以保持垂直向下运动，避免主体部1321发生晃动。主体部1321与固定部1322滑动连接，电动缸1351的第二驱动杆1351a向下伸出，可以与主体部1321的顶端相抵接，从而驱动主体部1321 在固定部1322上向下滑动。
如图7所示，主体部1321内还设置有中空的腔室1324，上述检测机构1360设置在腔室1324内。腔室1324在下端位置形成有开口状的检测口1325，检测口1325的尺寸大于推杆130，以便压配连接后为推杆130由阀体110端面凸出留出活动空间。检测机构1360包括测芯1361以及传感器1362，其中测芯1361设置在腔室1324内下部位置，测芯1361可以在腔室1324内上下移动。测芯1361在下端伸出有探针1361a，探针1361a穿过检测口1325可以由检测口1325向下露出。传感器1362设置在腔室1324内位于测芯1361的上部位置，传感器1362可以包括位移传感器以及力传感器，传感器1362与测芯1361相抵接，通过传感器1362可以检测测芯1361的位移量以及测芯1361所受到的压力。
图8为压配装置B1300进行压配的过程示意图。如图8中(a)部分所示，转动盘310转动使定位工装320转移到压配工位B后，阀体110、阀座120、弹簧、推杆130按照预定位置放置在定位工装320内。其中，阀座120的开口一端向下，设置在定位工装320内，阀体110压配在阀座120上部，阀座120的上端部分伸入到阀体110内，阀座120与阀体110的轴线重合。推杆130与弹簧放置在阀体110内，弹簧套设在推杆130一端，弹簧的一端与推杆130相抵接，另一端与阀座120相抵接，支撑推杆130与阀座120保持分离状态。
如图8中(b)部分所示，第一下压机构1340驱动压头1320向下移动进行第一压配。具体的，下压气缸1342控制第一驱动杆1342a伸出，从而驱动活动板1341向下移动，进而带动压头1320向下移动，使主体部1321的下端面(平面)与阀体110的上端面(平面)相抵接。主体部1321压迫阀体110向下移动，使阀座120进入阀体110通孔内的部分逐渐增加。当探针1361a抵接推杆130后相对于主体部下端面向上移动，测芯1361在主体部1321的腔室1324内发生位移，从而使传感器1362可以获取第一检测结果。第一检测结果可以包括推杆130上端与阀体110上端的距离，以及第一驱动杆1342a的驱动力。此时，第一下压机构1340停止向下移动，第一压配结束。
如图8中(c)部分所示，完成第一压配后，第二下压机构1350的第二驱动杆1351a向下伸出，与主体部1321的顶端相抵接后，推动主体部1321在固定部1322内向下滑动，从而使主体部1321继续压迫阀体110向下移动，使阀座120进入阀体110内的部分逐渐增加，使推杆130上端与阀体110上端的距离达到预定值。第二下压机构1350可以根据第一检测结果调整第二驱动杆1351a向下伸出的长度，从而使第二压配后推杆130上端与阀体110上端的距离满足精度要求。同时，传感器1362还可以在第二压配过程中，实时地对推杆130上端与阀体110上端的距离进行检测，从而获取第二检测结果。第二下压机构1350可以根据第二检测结果调整第二驱动杆1351a向下伸出的长度，从而提高推杆130上端与阀体110上端的距离的精度。
压配完成后，转动盘310转动，将阀座120、阀体110弹簧140以及推杆130输送到下料工位，第二移料装置1500可以通过机械爪将阀座120、阀体110弹簧以及推杆130转移到第三转盘装置400上。
如图3所示，第三转盘装置400与第一转盘装置200的结构相同，包括：转动盘410、定位工装420以及安装座430，此处不再赘述。围绕第三转盘装置400的转动盘 410的外侧边缘，设置有多个工位，可以包括上料工位、外壳与动铁上料工位、压配工位C以及下料工位。第二移料装置1500可以将压配后的阀座120、阀体110、弹簧140及推杆130由转动盘310的下料工位转移到第三转盘装置400位于上料工位的定位工装420上。
如图3所示，转动盘410的外侧边缘还可以设置第三检测工位，第三检测工位可以是气密性检测工位，在第三检测工位相应位置设置有第三检测装置1600，用于对推杆130与阀座120的阀口121相抵接后的气密性进行检测。检测完成后，转动盘410转动，将阀座120、阀体110、弹簧140与推杆130转移到外壳与动铁上料工位，由外壳与动铁上料装置1700在阀座120上放置外壳160与动铁150。
外壳160与动铁150放置在阀体110上后，转动盘410转动，将阀座120、阀体110、弹簧、推杆130、动铁150与外壳160转移到压配工位C。在压配工位C相应位置设置有压配装置C1800，压配装置C1800可以对定位工装420上的外壳160与阀体110进行压配，使阀体110进入到外壳160内预定位置，使外壳160与阀体110通过过盈配合实现固定，以便后续进行压配、焊接固定，同时避免转移过程中阀座120内的弹簧140、推杆130及动铁150发生位移，影响装配精度。
对外壳160与阀体110的压配完成后，转动盘410转动，将阀座120、阀体110、弹簧140、推杆130、动铁150与外壳160转移到下料工位。在第三转盘装置400前侧位置还设置有第三移料装置1900，可以通过机械爪将下料工位的定位工装420上装配完成的阀座120、阀体110、弹簧140、推杆130、动铁150与外壳160由定位工装420上取下，转移到下一个加工流程中。
