技术领域
本申请涉及动力电池技术领域,更具体的说,涉及一种焊接定位夹具。
背景技术
随着新能源汽车的普及和推广,新能源汽车的安全可靠性日益引起人们的关注和重视。动力电池为一种可充电的电池是新能源汽车的动力来源,在新能源汽车领域中被广泛应用。
目前,动力电池包括电池单体及箱体,箱体包括相盖合的第一部分第二部分,第二部分及第一部分之间焊接固定并形成具有容纳腔的箱体,电池单体容置于容纳腔内。箱体的第一部分及第二部分需要定位,并使二者之间的间隙保证在预设范围内,但现有的定位夹具中压块磨损无法有效定位,会使第一部分及第二部分之间的间隙(也即焊缝处)超过预设范围内,间隙处会漏激光而损伤电池单体。
发明内容
有鉴于此,本申请公开一种焊接定位夹具。
一种焊接定位夹具包括第一侧压装置,第一侧压装置用于沿第一方向定位工件,第一方向为工件的厚度方向;基座及安装板,安装板沿与第一方向垂直的第二方向可移动地设于基座,第一侧压装置设于安装板;定位装置,定位装置用于沿第三方向定位工件,第三方向与第一方向、第二方向分别垂直,定位装置沿第一方向滑设于安装板且盖设于第一侧压装置的上方;其中,第一侧压装置沿第一方向具有相对设置的活动侧及基准侧,第一侧压装置包括设于基准侧的第一侧压块及第一基准块、设于活动侧的第二侧压块,第二侧压块及第一侧压块均能沿第一方向移动,第一基准块在第一方向上的位置固定。上述的焊接定位夹具,第一侧压装置的基准侧设有第一基准块及第一侧压块,第一基准块位置固定并作为定位基准,第一侧压块在第一方向上可移动,即使第一基准块或第一侧压块中的一者磨损后,第一侧压 装置的基准侧与活动侧依然能配合压紧工件,改善因工件未压紧而在间隙处产生漏激光的风险。
在其中一实施例中,基准侧沿第二方向设有至少两个第一基准块,在第二方向上位于最外侧的两个第一基准块之间设有至少一个第一侧压块。如此,基准侧沿第二方向设有至少两个第一基准块,在第二方向上位于最外侧的两个第一基准块之间设有至少一个第一侧压块,当任一个第一基准块或第一侧压块磨损后,第一侧压装置的基准侧还能压紧工件,改善因第一基准块磨损而使工件定位出现偏差的情况。
在其中一实施例中,在第二方向上位于最外侧的两个第一基准块之间设有至少两个第一侧压块,第一侧压装置还包括与第一侧压块对应设置的第一驱动件,第一驱动件用于驱使第一侧压块沿第一方向移动。如此,在第二方向上位于最外侧的两个第一基准块之间设有至少两个第一侧压块,第一驱动件与第一侧压块对应设置,各第一侧压块的位置可独立控制并调整,改善因单个第一侧压块磨损而使基准侧定位出现偏差的情况。
在其中一实施例中,活动侧沿第二方向设有至少两个第二侧压块,第一侧压装置还包括与第二侧压块对应设置的第二驱动件,第二驱动件用于驱使第二侧压块沿第一方向移动。如此,活动侧沿第二方向设有至少两个第二侧压块,第二驱动件与第二侧压块对应设置,各第二侧压块的位置可独立控制并调整,减小因单个第二侧压块磨损而使活动侧定位出现偏差的风险。
在其中一实施例中,第二驱动件的驱动力小于第一驱动件的驱动力。如此,当第一侧压块及第二侧压块共同压紧工件时,由于第二驱动件的驱动力小于第一驱动件的驱动力,能有效保证第一侧压块将工件推向位于第一侧压块同一侧的第一基准块并压紧。
在其中一实施例中,焊接定位夹具还包括电性连接的控制器及检测装置,检测装置设于第二侧压块并用于检测第二侧压块的实际位移值,控制器根据实际位移值与预设位移值的差值控制检测装置是否发出警示信号。如此,检测装置能检测第二侧压块的实际位移值,控制器根据实际位移值与预设位移值的差值控制检测装置是否发出警示信号,从而有效判断第二侧压块是否有磨损,进一步改善因第二侧压块较大磨损而导致工件定位位置偏移的风险。
在其中一实施例中,焊接定位夹具还包括第二侧压装置,第二侧压装置用于沿第二方向定位工件。如此,除了在第一方向定位工件,还能在第二方向定位工件,利于提高定位的可靠性及准确性。
在其中一实施例中,第二侧压装置包括沿第二方向相对设置的第二基准块及第三侧压块,第三侧压块能沿第二方向移动,第二基准块在第二方向上的位置固定。如此,第二基准块位置固定并作为定位基准,第三侧压块在第二方向上可移动,通过第三侧压块与第二基准块的配合有效压紧工件。
在其中一实施例中,焊接定位夹具还包括升降装置,升降装置用于带动工件沿第三方 向移动。如此,升降装置用于带动工件沿第三方向移动,从而使工件在第三方向上调整位置。

随着新能源汽车的普及和推广,新能源汽车的安全可靠性日益引起人们的关注和重视。动力电池为一种可充电的电池是新能源汽车的动力来源,在新能源汽车领域中被广泛应用。
目前,动力电池包括电池单体及箱体,箱体包括相盖合的第一部分第二部分,第二部分及第一部分之间焊接固定并形成具有容纳腔的箱体,电池单体容置于容纳腔内。箱体的第一部分及第二部分需要定位,并使二者之间的间隙保证在预设范围内,但现有的定位夹具中压块磨损无法有效定位,会使第一部分及第二部分之间的间隙(也即焊缝处)超过预设范围内,间隙处会漏激光而损伤电池单体。
基于上述考虑,发明人经深入研究,设计了一种焊接定位夹具,第一侧压装置100的基准侧102设有第一基准块120及第一侧压块110,第一基准块120位置固定并作为定位基准,第一侧压块110在第一方向上可移动,即使第一基准块120或第一侧压块110中的一者磨损后,第一侧压装置100的基准侧102与活动侧101依然能配合压紧工件10,改善因工件10未压紧而在间隙处产生漏激光的风险。
请参考图1及图2,一实施例中的焊接定位夹具包括第一侧压装置100、基座500、安装板600及定位装置400,第一侧压装置100用于沿第一方向定位工件10,第一方向为工件10的厚度方向,安装板600沿与第一方向垂直的第二方向可移动地设于基座500,第一侧压装置100设于安装板600。定位装置400用于沿第三方向定位工件10,第三方向与第一方向、第二方向分别垂直,定位装置400沿第一方向滑设于安装板600且盖设于第一侧压装置100的上方。其中,第一侧压装置100沿第一方向具有相对设置的活动侧101及基准侧102,第一侧压装置100包括设于基准侧102的第一侧压块110及第一基准块120、设于活动侧101的第二侧压块130,第二侧压块130及第一侧压块110均能沿第一方向移动,第一基准块120在第一方向上的位置固定。
需说明的是,第一侧压装置100的活动侧101及基准侧102分别压置于工件10的两侧。结合图2所示,在沿第一方向(图1所示X方向)有效定位工件10前,先将工件10移动至预设高度,再将第二侧压块130沿第一方向移动并将工件10推向第一基准块120,第二 侧压块130移动至工件10抵接第一基准块120时停止移动,然后将第一侧压块110沿第一方向移动至抵接工件10时停止移动,以使第一侧压装置100的活动侧101及基准侧102共同压紧工件10。
此处,第二方向为图2所示Y方向,也即工件10的长度方向;第三方向为图1所示Z方向,第三方向为工件10的高度方向。在沿第三方向(图3所示Z方向)有效定位工件10前,先将工件10沿第三方向移动至抵接定位装置400,以使工件10在高度方向定位好后,再使工件10在第一方向及第二方向定位。
本申请的实施例中,定位装置400为定位板,定位板呈矩形板状以与工件10匹配。在其他实施例中,定位板还可以为其他形状。本申请的实施例中,安装板600上设有滑轨及设于滑轨上的滑块,定位装置400固定于滑块上,以使定位装置400能相对于安装板600滑动。
本申请的实施例中,工件10为方形电池。如图1所示,方形电池包括电池单体11及用于容纳电池单体11的箱体12,箱体12包括第一部分12a及第二部分12b,第一部分12a为一侧开放的空心结构,第二部分12b为板状结构,第二部分12b盖合于第一部分12a的开放侧以形成具有容纳腔的箱体12。利用上述焊接定位夹具将箱体12定位后,激光焊接固定第一部分12a及第二部分12b,焊接时需保证第一部分12a及第二部分12b之间的间隙(也即焊缝处)在预设范围内,以减小在间隙处漏激光而损伤电池单体11的风险。
本申请的实施例中,第一侧压装置100被配置为沿工件10的厚度方向压紧工件10的结构,第一侧压装置100中的第一侧压块110、第一基准块120及第二侧压块130的形状可以呈圆柱状、棱柱状或其他形状,第一侧压块110、第一基准块120及第二侧压块130的数量均不仅限于一。在此,对第一侧压块110、第一基准块120及第二侧压块130的形状及数量不作具体限定。
上述的焊接定位夹具,第一侧压装置100的基准侧102设有第一基准块120及第一侧压块110,第一基准块120位置固定并作为定位基准,第一侧压块110在第一方向上可移动,即使第一基准块120或第一侧压块110中的一者磨损后,第一侧压装置100的基准侧102与活动侧101依然能配合压紧工件10,改善因工件10未压紧而在间隙处产生漏激光的风险。
根据本申请的一些实施例,请参考图2,基准侧102沿与第一方向垂直的第二方向设有至少两个第一基准块120,在第二方向上位于最外侧的两个第一基准块120之间设有至少一个第一侧压块110。
本申请的实施例中,第一侧压块110与全部第一基准块120沿第二方向并排且等间距设置。例如图1所示,基准侧102沿第二方向设有两个第一基准块120及两个第一侧压块110,两个第一基准块120在第二方向上位于最外侧,两个第一侧压块110设于两个第一基准块120之间,两个第一基准块120及两个第一侧压块110沿第二方向并排且等间距设置。在其他实 施例中,第一侧压块110与全部第一基准块120还可以沿第二方向并排且不等间距设置。
通过上述设置,基准侧102沿第二方向设有至少两个第一基准块120,在第二方向上位于最外侧的两个第一基准块120之间设有至少一个第一侧压块110,当任一个第一基准块120或第一侧压块110磨损后,第一侧压装置100的基准侧102还能压紧工件10,改善因第一基准块120磨损而使工件10定位出现偏差的情况。
根据本申请的一些实施例,请参考图2,在第二方向上位于最外侧的两个第一基准块120之间设有至少两个第一侧压块110,第一侧压装置100还包括与第一侧压块110对应设置的第一驱动件140,第一驱动件140用于驱使第一侧压块110沿第一方向移动。
本申请的实施例中,第一驱动件140为气缸,第一驱动件140能够驱使第一侧压块110平移运动,以使第一侧压块110在第一方向调整位置。
本申请的实施例中,全部第一侧压块110沿第二方向并排且等间距设置。例如图1所示,基准侧102沿第二方向设有两个第一基准块120及两个第一侧压块110,两个第一基准块120在第二方向上位于最外侧,两个第一侧压块110设于两个第一基准块120之间,两个第一基准块120及两个第一侧压块110沿第二方向并排且等间距设置。在其他实施例中,全部第一侧压块110还可以沿第二方向并排且不等间距设置。
通过上述设置,在第二方向上位于最外侧的两个第一基准块120之间设有至少两个第一侧压块110,第一驱动件140与第一侧压块110对应设置,各第一侧压块110的位置可独立控制并调整,改善因单个第一侧压块110磨损而使基准侧102定位出现偏差的情况。
根据本申请的一些实施例,请参考图2,活动侧101沿第二方向设有至少两个第二侧压块130,第一侧压装置100还包括与第二侧压块130对应设置的第二驱动件150,第二驱动件150用于驱使第二侧压块130沿第一方向移动。
本申请的实施例中,第二驱动件150为气缸,第二驱动件150能够驱使第二侧压块130平移运动,以使第二侧压块130在第一方向调整位置。
本申请的实施例中,全部第二侧压块130沿第二方向并排且等间距设置。在其他实施例中,全部第人侧压块还可以沿第二方向并排且不等间距设置。
通过上述设置,活动侧101沿第二方向设有至少两个第二侧压块130,第二驱动件150与第二侧压块130对应设置,各第二侧压块130的位置可独立控制并调整,减小因单个第二侧压块130磨损而使活动侧101定位出现偏差的风险。
根据本申请的一些实施例,请参考图2,第二驱动件150的驱动力小于第一驱动件140的驱动力。
本申请的实施例中,第一驱动件140及第二驱动件150均为气缸,通过使第二驱动件150的缸径小于第一驱动件140的缸径,以满足第二驱动件150的驱动力小于第一驱动件140的驱动力。
可以理解的是,第二侧压块130及第一侧压块110在工件10的不同侧压置工件10,第二驱动件150用于驱使第二侧压块130沿第一方向移动,第一驱动件140用于驱使第一侧压块110沿第一方向移动。
通过上述设置,当第一侧压块110及第二侧压块130共同压紧工件10时,由于第二驱动件150的驱动力小于第一驱动件140的驱动力,能有效保证第一侧压块110将工件10推向位于第一侧压块110同一侧的第一基准块120并压紧。
根据本申请的一些实施例,请参考图2,焊接定位夹具还包括电性连接的控制器及检测装置200,检测装置200设于第二侧压块130并用于检测第二侧压块130的实际位移值,控制器根据实际位移值与预设位移值的差值控制检测装置200是否发出警示信号。
可以理解的是,当第二侧压块130压置于工件10时,检测装置200检测第二侧压块130的实际位移值并产生对应的位移信号,控制器接收位移信号并将实际位移值与预设位移值进行比对,当实际位移值与预设位移值差值较大时,说明第二侧压块130有较大磨损会导致工件10压紧位置偏移,此时控制器控制检测装置200发出警示信号。
具体到本实施例中,检测装置200包括磁栅尺及读数头,磁栅尺固定于第二侧压块130,磁栅尺随第二侧压块130移动,读数头用于获取磁栅尺的位置信息并产生位移信号,控制器用于接收读数头输出的位移信号并判断检测装置200是否发出警示信号。在其他实施例中,检测装置200还可以为光电检测器或其他能测距的元件或结构。
本申请的实施例中,检测装置200的数量不仅限于一,也即检测装置200的数量可以为至少两个。例如图1所示,在第二方向上并排等间距设有四个第二侧压块130,在第二方向上位于最外侧的两个第一侧压块110均对应设有一个检测装置200,从而判断上述两个第一侧压块110是否有磨损。
通过上述设置,检测装置200能检测第二侧压块130的实际位移值,控制器根据实际位移值与预设位移值的差值控制检测装置200是否发出警示信号,从而有效判断第二侧压块130是否有磨损,进一步改善因第二侧压块130较大磨损而导致工件10定位位置偏移的风险。
根据本申请的一些实施例,请参考图2,焊接定位夹具还包括的第二侧压装置300,第二侧压装置300用于沿第二方向定位工件10。
通过上述设置,除了在第一方向定位工件10,还能在第二方向定位工件10,利于提高定位的可靠性及准确性。
根据本申请的一些实施例,请参考图2,第二侧压装置300包括沿第二方向相对设置的第二基准块310及第三侧压块320,第三侧压块320能沿第二方向移动,第二基准块310在第二方向上的位置固定。
本申请的实施例中,第二侧压装置300还包括与第三侧压块320连接的第三驱动件,第三驱动件用于驱使第三侧压块320在第二方向移动。可选地,第三驱动件为气缸。
本申请的实施例中,第二基准块310及第三侧压块320的数量不仅限于一,也即第二基准块310与第三侧压块320的数量还可以均为至少两个,以增加在第二方向上的定位点。
需说明的是,在沿第一方向上定位好工件10后,第三侧压块320沿第二方向移动并推动工件10移动至抵接第二基准块310,使工件10沿第二方向定位。
通过上述设置,第二基准块310位置固定并作为定位基准,第三侧压块320在第二方向上可移动,通过第三侧压块320与第二基准块310的配合有效压紧工件10。
根据本申请的一些实施例,请参考图2及图3,焊接定位夹具还包括升降装置,升降装置用于带动工件10沿第三方向移动。
可以理解的是,基座500及安装板600均设有供工件10定位的定位槽601,工件10由下至上被送入定位槽601内,使工件10在第三方向上移动至抵接于定位装置400;再将第二侧压块130沿第一方向移动并将工件10推向第一基准块120,第二侧压块130移动至工件10抵接第一基准块120时停止移动,然后将第一侧压块110沿第一方向移动至抵接工件10时停止移动,以使第一侧压装置100的活动侧101及基准侧102沿第一方向共同压紧工件10;第三侧压块320沿第二方向移动并推动工件10移动至抵接第二基准块310,使工件10沿第二方向定位。
通过上述设置,升降装置用于带动工件10沿第三方向移动,从而使工件10在第三方向上调整位置。
根据本申请的一些实施例,参见图1至图3,本申请提供了一种焊接定位夹具,焊接定位夹具包括第一侧压装置100、控制器、检测装置200、第二侧压装置300、定位装置400、基座500、安装板600及升降装置,第一侧压装置100用于沿第一方向定位工件10,第一方向为工件10的厚度方向,第二侧压装置300用于沿第二方向定位工件10。
其中,第一侧压装置100包括第一侧压块110、第一基准块120、第二侧压块130、第一驱动件140、第二驱动件150,第一侧压装置100沿第一方向具有相对设置的活动侧101及基准侧102,基准侧102沿与第一方向垂直的第二方向设有至少两个第一基准块120,在第二方向上位于最外侧的两个第一基准块120之间设有至少两个第一侧压块110,第一驱动件140用于驱使第一侧压块110沿第一方向移动,活动侧101沿第二方向设有至少两个第二侧压块130,第二驱动件150用于驱使第二侧压块130沿第一方向移动,第二侧压块130及第一侧压块110均能沿第一方向移动,第一基准块120在第一方向上的位置固定,第二驱动件150的驱动力小于第一驱动件140的驱动力。第二侧压装置300包括沿第二方向相对设置的第二基准块310及第三侧压块320,第三侧压块320能沿第二方向移动,第二基准块310在第二方向上的位置固定,定位装置400用于沿第三方向定位工件10,第三方向与第一方向、第二方向分别垂直,升降装置用于带动工件10沿第三方向移动。
