Description

链条疲劳试验组合工装 技术领域
本实用新型涉及链条疲劳测试设备技术领域，具体为链条疲劳试验组合工装。
 背景技术
现有的低频疲劳试验机夹头有 3 种型号（宽度分别为：61mm、46mm、36mm），在更换不同的型号的时候需要以下步骤：1、低频疲劳试验机夹头连接链条夹头及链条；2、通过移动横梁或下底座进行加载，使链条受力（20kN 左右）；3、用活动扳手（型号 24″，重量 4 公斤）松动紧固螺母；4、通过移动横梁或下底座卸载链条受力；5、取出链条及链条夹头，拧出低频疲劳试验机夹头及紧固螺母。另外安装时需要以下步骤：1、安装紧固螺母及低频疲劳试验机夹头；2、调整位置，安装链条并加载，使链条受力；3、拧紧紧固螺母，固定低频疲劳试验机夹头；4、卸载链条受力，取出链条。
 技术问题
以上这个拆卸或安装过程中，由于低频疲劳试验机上夹头高度较高，人需要站在30cm高的平台上松紧螺母，又因为活动扳手较重，长时间手持后，手臂会有一定程度的酸痛感，整个更换夹头的过程的劳动强度较大，而且操作过程当中也有一定的安全隐患。
 技术解决方案
本实用新型的目的在于提供一种链条疲劳试验组合工装，具有结构简单、组合式更换方便、降低劳动强度和提升工作效率。
为实现上述目的，本实用新型提供如下技术方案：链条疲劳试验组合工装，包括：底座、组合式夹头、链条夹具以及一组垫块，所述底座与组合式夹头可拆卸连接，组合式夹头内通过相应厚度的垫块将对应的链条夹具配合进行固定，链条夹具用于安装链条。
优选的，所述组合式夹头包括螺纹底座和一组侧板，螺纹底座上下两侧连接侧板，底座上设有螺纹孔，螺纹底座由连接柱和连接块组成，连接柱与底座上的螺纹孔连接，连接柱内安装有紧固螺母，连接柱与底座上的螺纹孔连接，连接块上下两侧与侧板可拆卸连接。
优选的，所述连接块为T型结构，侧板一侧设置有卡槽，连接块两侧的凸起部分别与上下两侧的卡槽配合定位，且侧板与连接块通过至少一个连接件连接，可以进行预先定位，再组合连接，整体连接结构稳定牢固。
优选的，所述连接块两侧的凸起部上均设有至少一个第一连接孔，侧板上设有通往卡槽的第一连接孔，连接块与侧板卡槽配定位后，通过连接件安装于两个第一连接孔内进行固定。
优选的，位于连接块两侧与其垂直的面上设有第一固定孔，卡槽的侧面设置有与固定孔相适配的第二固定孔。
优选的，侧板上还设有第二连接孔和第三连接孔，垫块上设有与第二连接孔相对应的第四连接孔，与第三连接孔相对应的第五连接孔。
优选的，所述链条夹具上下侧面上设有与第二连接孔对应的第六连接孔。
 有益效果
与现有技术相比，本实用新型的有益效果是：
对组合式夹头进行了改进，使原先为整体式的改成组合式，在更换链条夹具型号的时候，不需要再把整的一套结构全部拆开，只需要添加相应垫块或者更换侧板就能够满足需求，整个过程不仅减少了工作量，也降低了劳动强度，减少了相应的安全隐患。

实施例1
请参阅图1-图6，链条疲劳试验组合工装，包括，底座1、组合式夹头2、链条夹具3以及一组垫块4，所述底座与组合式夹头2可拆卸连接，组合式夹头2内通过相应厚度的垫块4将对应的链条夹具3配合进行固定，垫块4厚度和夹具内部大小可以根据需要测试的链条尺寸进行调整，能兼容多种尺寸。
所述组合式夹头2包括螺纹底座和一组侧板23，螺纹底座上下两侧连接侧板23，底座上设有螺纹孔，螺纹底座由连接柱21和连接块22组成，连接柱21与底座上的螺纹孔连接，连接柱21内安装有紧固螺母24，连接柱21与底座上的螺纹孔连接，连接块22上下两侧与侧板23可拆卸连接，链条夹具3用于安装链条。
本实施例中，所述连接块22为T型结构，侧板23一侧设置有卡槽25，连接块22两侧的凸起部分别与一组侧板23上的卡槽25配合定位，定位完成再进行连接，连接方式为在连接块22两侧的凸起部上均设有两个第一连接孔5，同样侧板23上设有通往卡槽25的第一连接孔5，连接件通过螺纹连接的方式与两个第一连接孔5连接，从而将侧板23与连接块22固定，整体连接结构稳定牢固。
本实施例中，所述侧板23上还设有第二连接孔6和第三连接孔9，垫块4上设有与第二连接孔6相对应的第四连接孔10，与第三连接孔9相对应的第五连接孔11，所述链条夹具3上下侧面上设有与第二连接孔6对应的第六连接孔。螺栓件旋转进入第二连接孔6、第四连接孔10以及第六连接孔，用于固定链条夹具3，本实施例中可以一根螺栓件穿过两个侧板23进行固定，而第三连接孔9和第五连接孔11通过螺栓件连接用于固定垫块4。
实际操作时，螺纹底座与底座先连接，一组侧板23再安装于螺纹底座上下两侧，进一步根据链条尺寸，选择匹配的链条夹具3和垫块4固定于侧板23之间，进一步安装链条并加载，使链条受力，再拧紧紧固螺母24，最后进行卸载链条受力测试，本实用新型方案对组合式夹头2进行了改进，使原先为整体式的改成组合式，在更换链条夹具3型号的时候，不需要再把整的一套结构全部拆开，只需要添加相应垫块4或者更换侧板23就能够满足需求，整个过程不仅减少了工作量，也降低了劳动强度，减少了相应的安全隐患。
实施例2
请参阅图4-图5，本实施方式区别于实施例1，位于连接块22两侧与其垂直的面上设有第一固定孔7，卡槽25的侧面设置有与固定孔相适配的第二固定孔8。第一固定孔7和第二固定孔8可以进一步安装螺栓件，能更好的固定组合式夹头2。
