如图5所示，为了便于将吸能盒准确的放置在本装置上，在夹爪42内侧的座板41上还设有吸能盒定位支撑组件7，本发明实施例的吸能盒定位支撑组件包括螺栓连接在底座上L型基准块71和调整块72，L型基准块71与调整块72螺栓连接，在调整块72上侧设有支撑块73和吸能盒定位销74，吸能盒定位销74的上端高于调整块72的上表面，并且，吸能盒定位销74的上端部优选设置呈锥形状，以便放入。L型基准块71与调整块72的两个边部之间设有多个不同厚度的调整垫片，从而可以通过减掉相应厚度的调整垫片调节吸能盒定位销74的前后和左右两个方向上的位置，以便与吸能盒上的定位孔对应。在调整块72与支撑块73之间也设有多个不同厚度的调整垫片，从而可以通过减掉相应厚度的调整垫片可以调节支撑块73的高度。为了防止人工放错吸能盒，在座板41上侧还设有防错销78，防错销78与吸能盒底部上的防错孔位置对应，当吸能盒的方向防错时无法放下。
如图5所示，为合理利用座板41下侧的空间，本发明实施例的夹爪控制气缸43设置在座板41的下侧，在座板41上设有供连接臂44穿过的穿孔411，连接臂44穿插设置在穿孔411内。
如图5和12所示，焊接完成后，为了便于将保险杠取下，在调整块72和座板41上均设有若干通孔412，在座板41的下侧设有吸能盒顶升气缸75，吸能盒顶升气缸75连接有连接块76，连接块76的上侧设有若干顶杆77，顶杆77穿插设置在通孔412内。吸能盒顶升气缸75在收缩状态下，顶杆77的上端低于支撑块73的上表面，吸能盒顶升气缸75在伸出状态下，顶杆77的上端高于吸能盒定位销74和防错销78的上端。焊接完成后，吸能盒夹紧机构4和主梁压紧机构松开，吸能盒顶升气缸75通过顶杆77向上顶起保险杠，从吸能盒定位销74、防错销78和主梁定位销65上脱离，进而便于取下保险杠。为了提高顶起的稳定性，顶杆77优选为两个，并且两个顶杆77分别设置在吸能盒定位销74的两侧。
如图1所示，为了便于将本装置安装在变位机上，在侧梁12的外侧连接有变位机转接板16，通过将转接板16进而将底架1安装在变位机上。为了便于检测，在侧梁12上侧设有校准板9，在校准板9上设有三坐标基准孔91，三坐标基准孔91作为检测各个部件三坐标的基准点。为了为焊接机器人提供作业参照物，在校准板9上还设有TCP组件92。 
如图3所示，为了提高底架1的结构强度，在底梁11与侧梁12和承载梁14之间、连接梁15与承载梁14和第二连接板46之间以及侧梁12与变位机转接板16之间均设有加强筋板。由于安装在变位机上后，底梁11与侧梁12之间的应力较大，所以在底梁11与侧梁12之间采用两道加强筋板17，并且，加强筋板17呈L型状。底梁11与承载梁14之间、连接梁15与承载梁14和第二连接板46之间以及侧梁12与变位机转接板16之间优选采用三角型状加强筋板。
作为优选实施例，在滑板25的前侧固定设有滑块26，在竖板242的背侧设有与滑块26配合的滑轨27，采用滑块滑轨机构还可对滑板25进行侧向限位，从而保证滑板25稳定的上下运动。在竖板242的中部设有竖向开口243，滑板25的前侧通过若干连接块28连接有前板29，连接块28设置在竖向开口243内，进而，连接块28不影响滑板25上下滑动。前板29优选与竖板242间隔设置，两个压梁22分别固定在前板29的两侧，压梁气缸23伸缩时，通过滑板25、连接块28、前板29带动压梁22上下运动，进而实现松开主梁和将主梁压在吸能盒上侧。
如图2和4所示，本发明实施例的主梁压紧组件包括设置在压梁22下侧的压轮51和气动压块组件52，气动压块组件52设置在压轮51的外侧，本发明实施例的气动压块组件包括下压气缸53和与下压气缸53连接的下压块54，在压轮51与压梁22之间设有缓冲弹簧55。当主梁放置在本装置上后，先通过侧压机构将主梁侧向压紧，然后通过顶升组件带动压梁22下行，先通过压轮51将主梁压在吸能盒上，然后下压气缸53在向下推动下压块54，进一步将主梁压紧。缓冲弹簧55与侧压气缸限位块34可以减小主梁夹紧动作的冲击。
如图1、2和9所示，为了防止主梁放置在本装置上时，出现位置偏差，在底架1上侧还设有主梁定位组件6，主梁定位组件6包括台座61，台座61呈工型状，台座61的底部固定在底架1上，在台座61的上侧螺栓连接有第一调整块62，在第一调整块62的一侧螺栓连接有定位块63，定位块63侧部螺栓连接有第二调整块64，第二调整块64上设有主梁定位销65，在第一调整块62与定位块63之间以及定位块63与第二调整块64之间分别设有多个不同厚度的调整垫片。通过增减调整垫片，进而使主梁定位销65的位置在前后和左右两个方向上可以调节，以便与主梁上的定位孔位置对应。以第一调整块62与定位块63之间以及定位块63与第二调整块64之间的调整间隙为3mm为例，所采用的调整垫片可以为五个，优选的厚度分别是两个1mm的调整垫片、一个0.5mm的调整垫片、一个0.3 mm的调整垫片和一个0.2mm的调整垫片，根据不同的误差减掉相应尺寸的调整垫片，即可调整主梁定位销65的位置。
如图11所示，为了主梁防止在焊接过程中出现形变，在底架1上侧还设有辅助支撑块8，辅助支撑块8设置在两个侧压机构3之间。本发明实施例的辅助支撑块8包括固定在第一底架1上侧的第一辅助支撑块81和通过埋头螺栓连接在第一辅助支撑块81上端的第二辅助支撑块82，第一辅助支撑块81呈L型状，第二辅助支撑块82优选采用304钢块，以防划伤主梁。
如图1、5和9所示，本发明实施例还集成了打标机100，打标机100通过打标机转接板101固定在前板29的前侧，打标机100设置在两个压梁22之间。在吸能盒夹紧机构4的一侧还设有一个接近开关103，接近开关103用来检测是否有吸能盒放入，接近开关103优选通过支架安装在第二连接板46的上侧。在台座61的上侧还通过支架接近开关104，接近开关104用来检测是否有主梁放入。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，其它未具体描述的部分，属于现有技术或公知常识。在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
