具体实施方式
以下结合附图对本发明作进一步详细说明。
如图1所示，一种传动轴生产线，包括桁架50以及设置在桁架50上的滑道51。桁架50的下方从左至右依次设置的三部件传送机构52、传动轴压装机53、校直焊接机54、中端冷却传送架55、校直机56、动平衡机57以及产品输 出传送架58。三部件传送机构52用以将传动轴头8、传动轴管10以及传动轴尾9分别向传动轴压装机53侧进行输送。
滑道51上滑动设置有可将三部件传送机构52上的传动轴头8、传动轴管10以及传动轴尾9同时向传动轴压装机53上转运的第一转运机构59，所述第一转运机构59还将传动轴压装机53上压装完毕的传动轴再次转运至校直焊接机54上进行焊接、校直作业。
滑道51上还滑动设置有转运机械手60，该转运机械手60可将校直焊接机54上经过加工完毕的传动轴依次向中端冷却传送架55、校直机56以及动平衡机57上进行转运，并最终转运至产品输出传送架58上。
当生产线开始工作时，通过三部件传送机构52将工件(传动轴头8、传动轴管10以及传动轴尾9)输送到设定位置，由桁架50上设置的第一转运机构59来回移动抓取工件放置于传动轴压装机53上进行压装工序，而后再由第一转运机构59抓取工件至下一道工序校直焊接机54进行加工，为了加快生产节拍，该生产线上设有若干架校直焊接机54，经过校直焊接机54的检测和焊接后，工件被放置于中端冷却传送架55上进行冷却，冷却后由转运机械手60放到校直机56上进行再次检测，接着由转运机械手60将工件置于动平衡机57上进行旋转过程中的平衡性能检测与校正，最后再由转运机械手60将工件运送至产品输出传送上输出产品。
进一步的，三部件传送机构52包括三台输送机(附图未示出)，该三台输送机可分别输送传动轴头8、传动轴管10以及传动轴尾9。
进一步的，第一转运机构59以及转运机械手60的一侧均设置有可驱动其在滑道51上往复移动的第三驱动件(附图未示出)。
如图2-图10所示，传动轴压装机53包括具有滑轨1的机架2，滑轨1上 滑动连接有第一可移推力机3以及第二可移推力机4。机架2的两端分别设置有第一压力机5、第二压力机6，第一压力机5、第二压力机6中至少一个可驱动第一可移推力机3以及第二可移推力机4朝着相互靠近的方向进行移动。
滑轨1上还滑动连接有两个第一轴颈夹具7，两个第一轴颈夹具7分别对传动轴头8、传动轴尾9进行夹紧固定。两个第一轴颈夹具7之间设置有若干个可对传动轴管10夹紧固定的第二轴颈夹具11。两个第一轴颈夹具7以及若干个第二轴颈夹具11可使传动轴头8、传动轴尾9以及传动轴管10保持同轴心设置。
在具体压装作业时，通过两个第一轴颈夹具7以及若干个第二轴颈夹具11可使传动轴头8、传动轴尾9以及传动轴管10保持同轴心设置。然后再通过两个压力机分别驱动第一可移推力机3以及第二可移推力机4朝着相互靠近的方向进行移动。使传动轴头8、传动轴管10以及传动轴尾9压装成一整体，即传动轴。
进一步的，第一压力机5包括有机壳12，机壳12的一侧穿设有两个相互独立的推力杆13和连动杆14，推力杆13与连动杆14的同一端通过固定板15固定连接。推力杆13的另一端与第一可移推力机3/第二可移推力机4固定连接或抵接。机壳12的一侧设置有可驱动连动杆14沿其轴向往复移动的驱动机构16。
推力杆13的一侧设置有若干个限位孔17，机壳12的一侧还设置有可与限位孔17相配合的限位气缸18，限位气缸18的伸缩端可穿过机壳12于其内部与限位孔17配合。
在具体使用时，由驱动机构16带动连动杆14往复运动，由于连动杆14与推力杆13的同一端通过固定板15连接，使得连动杆14往复运动时会同步带动推力杆13往复运动，进而通过推力杆13作用于第一可移推力机3/第二可移推力机4，使第一可移推力机3/第二可移推力机4在滑轨1上运动。
此外，由于本申请强调的应用领域为压装，因此在压装过程中会存在力的反作用力。当对第一可移推力机3/第二可移推力机4推动至一定位置后，由限位气缸18做出伸出运动与推力杆13上的限位孔17配合定位，避免力反作用于驱动机构16，以保护驱动机构16。
进一步的，驱动机构16包括有电机、大皮带轮、小皮带轮以及皮带。机架2上设置有用以固定电机的电机安装座，电机的输出端穿过电机安装座与小皮带轮的轴心处相连，小皮带轮与大皮带轮之间通过皮带连接，大皮带轮的轴心穿设有转动杆19，转动杆19穿入机壳12内的一端设置有轴承座20，且该轴承座20固设于机壳12内壁。
转动杆19于机壳12内的一端设置有齿轮21，连动杆14的表面上开设有若干可与齿轮21相配合的凹槽22，齿轮21的转动可通过相配合的凹槽22带动连动杆14延其轴向运动。
进一步的，第一可移推力机3/第二可移推力机4均包括有可与滑轨1相配合的移动座23，移动座23的一侧设置有可与推力杆13固定连接或抵接的联轴法兰24，移动座23的另一侧设置有法兰定位榫25。传动轴头8以及传动轴尾9上均设置有可与法兰定位榫25相配合的法兰孔26。
压装时，推力杆13作用于移动座23一侧的联轴法兰24，以推动移动座23。使得移动座23一侧的法兰定位榫25可插入传动轴头8/传动轴尾9上的法兰孔26内。通过法兰定位榫25与传动轴头8/传动轴尾9上的法兰孔26相配合，以限定传动轴头8/传动轴尾9的位置高度，且进一步保证传动轴头8与传动轴尾9呈同轴心设置。
需说明的是，本实施例中说明的传动轴头8相当于背景技术中指出的万向节叉，传动轴尾9相当于背景技术中指出的浮动连接套。由于万向节叉、浮动 连接套作为传动轴的两端，在本身的构造中便会设置法兰孔26。而本申请是针对传动轴本身的结构加以利用，以提高安装效率以及精度。
进一步的，第一可移推力机3/第二可移推力机4还包括推出气缸27，推出气缸27设置在气缸座28上，气缸座28的一端与移动座23固定连接。推出气缸27的伸缩端穿过气缸座28的一端配合有抵接块29，该抵接块29位于第一轴颈夹具7上。当气缸座28的一侧运动至与抵接块29相接触时，法兰定位榫25与传动轴头8/传动轴尾9定位到位。
当推力杆13带动移动座23的运动，使法兰定位榫25的一端插入工件(指的是传动轴头8以及传动轴尾9)的法兰孔26内，继续推动第一可移推力机3/第二可移推力机4运动至气缸座28与抵接块29接触的位置，此时法兰定位榫25与工件定位到位。当工件完成压装需要分离法兰定位榫25时，推出气缸27做伸出运动作用于抵接块29，使工件与法兰定位榫25分离。
进一步的，第一轴颈夹具7以及第二轴颈夹具11均包括有一对夹指30，一对夹指30相向的一侧均设置有夹持缺口31，该夹持缺口31可与传动轴头8/传动轴尾9、传动轴管10相配合。每个夹指30的下方均设置有摆臂32，每个摆臂32朝向另一摆臂32的一侧均设置有置物槽33，两个置物槽33内均设置有同一个旋转臂34，旋转臂34的两端分别与两个摆臂32转动连接。
每个摆臂32上均设置有限位块35，两个限位块35分别位于一对夹指30的两端，用以限制一对夹指30朝着相互远离方向移动的最大位移。其中一个限位块35的一侧设置有推杆49电机36，推杆49电机36的输出端穿过限位块35与夹指30固定连接。
每个摆臂32的一侧均穿设有连接杆37，每个连接杆37的一端与限位块35的下端面固定连接，每个连接杆37的另一端固定连接有滑块38，每个滑块38 均与滑轨滑动连接。
当工件放置于一对夹指30所形成的夹持缺口31内时，推杆49电机36的输出端作用于其中一个夹指30上，此时两个摆臂32会绕旋转臂34的两端铰接点进行转动。使得一对夹指30朝着相互靠近的方向进行运动，从而实现对工件的夹角。需特别说明的是：一对夹指30的运动位移是相同的，即其中一个夹指30运动多少位移，则另一个夹指30也会运动多少位移。因此，可使得传动轴头8、传动轴尾9以及传动轴管10保持同轴心设置。
进一步的，旋转臂34的一侧穿设有中间销39，中间销39的上端设置有用以支撑工件的支撑托40，支撑托40与旋转臂34之间设置有第一弹簧41，第一弹簧41的一端与旋转臂34上端面相抵，第一弹簧41的另一端与支撑托40下端面相抵。
首先，本申请在旋转臂34的中部设置中间销39，使得在推杆49电机36的作用下，旋转臂34可饶中间销39转动。同时摆臂32会绕与旋转臂34的铰接点做旋转运动，向着夹紧的方向旋转。在夹紧的过程中，第一弹簧41自适应工件调整，避免压装时出现对位不齐影响压装质量。当需要松开夹指30时，反向驱动推杆49电机36使得旋转臂34和摆臂32反方向旋转松开夹指30。
进一步的，机架2上还设置有齿条42，齿条42沿机架2长度方向设置。齿条42上啮合有驱动轮43，驱动轮43的一侧设置有抵接于齿条42侧边的支架44，支架44的一侧设置有移动电机45，移动电机45的输出端穿过支架44与驱动轮43固定连接。支架44的一侧设置有连接件46，该连接件46可与第一轴颈夹具7或第二轴颈夹具11相连接。
通过连接件46将上述部件与任意第一轴颈夹具7或第二轴颈夹具11连接，从而使两个第一轴颈夹具7、若干个第二轴颈夹具11，中的其中一个或多个或 全部均具备移动效果，进而对所需夹紧部位进行夹紧。
进一步的，第一轴颈夹具7还包括有固定托47，该固定拖可将传动轴头8或传动轴尾9进行支撑，该固定托47可与支撑托40相连(附图未示出)。
进一步的，第二压力机6包括推杆箱48和推杆49，推杆49穿过推杆箱48的一端与第二可移推力机4相抵。
传动轴压装机工作过程：
1、将传动轴头8以及传动轴尾9放置于第一轴颈夹具7的固定托47上，将传动轴管10放置于第二轴颈夹具11的支撑托40上。
2、启动压力机，进而驱动第一可移推力机3/第二可移推力机4，让法兰定位榫25插入工件的法兰定位孔内停止运动，进行预定位。
3、第一轴颈夹具7以及第二轴颈夹具11，启动推杆49电机36，让夹指30朝着相互靠近的方向运动，对工件夹紧。
4、再驱动压力机，让三者压合成一整体。即完成传动轴压装。
此外，上述步骤2的预定位过程，即法兰定位榫25插入工件的法兰定位孔内。也可通过移动电机45驱动第一轴颈夹具7在滑轨1上移动而完成。本发明也应保护并保护该技术方案。
此外，上述步骤4的压装过程，以压力机为主，以移动电机45驱动第一轴颈夹具7/第二轴颈夹具11在滑轨1上移动为辅。共同完成压装过程。
如图11-图17所示，校直焊接机54包括有架体61、工作台62、主轴头A63、主轴头B64以及用于监测传动轴圆周跳动的检测机构65，主轴头A63与主轴头B64分别将汽车传动轴两端进行固定。
工作台62的上方设置有焊接机构66，架体61上设置有可对焊接机构66的空间位置进行调整的驱动组件67。在驱动组件67的作用下，焊接机构66对汽 车传动轴待焊部位进行焊接。
在具体使用时，先将传动轴放置于架体61上，并通过主轴头A63与主轴头B64分别将汽车传动轴两端进行固定，此外主轴头A63还可以带动传动轴进行转动，其校直机56的具体工作过程可参阅我司在先申请的专利。
驱动组件67通过调整焊接机构66的空间位置，使得焊接机构66对汽车传动轴待焊部位进行焊接。由于传动轴在主轴头A63的作用下在工作台62上发生转动，此时焊接机构66与传动轴进行相对转动，进而焊接机构66可实现对传动轴的周向焊接。
进一步的，焊接机构66优选为两个，且分别对应于传动轴两端的待焊接部位。该待焊接部位为传动轴管10两端分别和传动轴头8、传动轴尾9的连接处。
进一步的，驱动组件67包括垂直导轨68以及与垂直导轨68滑动连接的第一滑座69，垂直导轨68的一端设置有可驱动第一滑座69在垂直导轨68上移动的第一驱动件70。该第一滑座69的一侧与焊接机构66固定连接。
通过第一驱动件70可调整焊接机构66在垂直方向上的高度，当工作台62上未放置有传动轴，则第一驱动件70驱动焊接机构66向上移动，使得焊接机构66与工作台62之间的间距拉大，以便于传动轴放置于工作台62上；当工作台62上放置有传动轴时，第一驱动件70控制焊接机构66下移，从而实现对传动轴的焊接。需特别说明的是：本申请所述的垂直，是指垂直于工作台62的方向。
进一步的，驱动组件67还包括有与架体61相连接的水平导轨71，水平导轨71上滑动连接有第二滑座72，第二滑座72的一侧与垂直导轨68固定连接，水平导轨71的一端设置有可驱动第二滑座72在水平导轨71上移动的第二驱动件73。
通过第二驱动件73的作用下，可调整垂直导轨68的在水平方向上的移动，进而调整焊接机构66在水平方向上的移动。由于传动轴的规格长度不一，在针对不同传动轴进行焊接时需先调整焊接机构66的水平位置。需特别说明的是：本申请所述的水平，是指沿工作台62长度方向水平设置。
进一步的，工作台62上设置有两段独立的导轨74，每段导轨74均滑动连接有移动板75，两个移动板75分别对主轴头A63以及主轴头B64进行支撑。每段导轨74的一端均设置有可驱动移动板75进行移动的第四驱动件(附图未示出)，两个移动板75均穿设有同一个用以保护导轨74的遮挡件76。
通过第四驱动件，调整主轴头A63以及主轴头B64之间的距离，以适应不同长度的传动轴的夹紧。此外，由于焊接过程中会产生火花或其它碎屑，且导轨74是精密导轨74。为避免焊接过程中的火花或碎屑对导轨74造成损坏，因此需要采用遮挡件76进行遮挡。
进一步的，每段导轨74均由两个相互平行的驱动轨道组成，每个驱动轨道上均滑动连接有活动块77，两个活动块77的上端面与同一个移动板75固定连接。每个活动块77朝向另一活动块77的一侧均设置有可与遮挡件76相配合的让位槽78。
进一步的，遮挡件76包括有具有容纳槽79的固定板15，该容纳槽79可用于盛放焊接时所产生的琐屑等杂质。固定板15的两端设置有可与让位槽78相配合的折边80。
进一步的，两个移动板75上均套设有用以分别保护主轴头A63以及主轴头B64的保护罩81。通过保护罩81，可实现对保护主轴头A63以及主轴头B64的保护。
此外，由于检测机构65中具有检测器85，为避免焊接过程对检测器85造 成损坏。本申请还对检测机构65进行改进，具体如下：
进一步的，检测机构65包括与主轴头相连的测架82，测架82的一侧铰接有转动块83，转动块83的一端设置有位于传动轴上方的压杆84，转动轴的另一端与抵接有检测器85。使得压杆84能够贴合在传动轴的表面，并通过检测器85对压杆84所接触的传动轴圆周跳动进行检测，便于让生产者通过检测机构65对传动轴的校直精度进行检测。
测架82的顶部设置有用以固定检测器85的顶板86，顶板86上还设置有用以保护检测器85不受焊接影响的挡板87。挡板87与转动块83之间设置有第二弹簧88，在第二弹簧88的作用下，位于转动板一端压杆84与传动轴表面相接触，位于传动板的另一端与检测器85相接触。
通过第二弹簧88的设置，可有效提高压杆84与传动轴接触后的贴合牢固性，避免压杆84进行跳动，错位的可能，有效提高压杆84所接触传动轴跳动的精确性。此外，挡板87可有效防护检测器85不受焊接影响。
进一步的，工作台62上设置有用以保护检测机构65的保护壳89，保护壳89上开设有可供压杆84穿出的开口90。
进一步的，校直机56为现有技术，具体可参照我司在先申请的专利。在此不进行详细赘述。
具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
