所述架体1包括一底架10、立设于所述底架10左右端的左侧架及右侧架、连接于所述左侧架及右侧架顶端的顶架11。本实施例中，所述底架10具有一底板101(或底座)以及设于所述底板101下表面的支脚100，所述支脚100可以是带有锁死功能的万向轮。所述左侧架及右侧架均为侧板(下称左侧板102和右侧板103)，所述顶架11为呈水平状 的顶板。所述底板101的宽度大于所述顶板104、左侧板102以及右侧板103的宽度，所述左侧板102立设于所述底板101的左侧的后段，所述右侧板103立设于所述底板101的右侧的后段(相应于所述左侧板102的位置处)，所述顶板104宽度与左/右侧板103一致，连接于所述左侧板102及右侧板103顶端后，在水平的投影上，所述顶板104位于所述底板101的后段位置处。这样设置，可以便于传感器装载机构4安装，便于所述秤盘5放置于所述底板101的前部，增加结构布局紧凑性，由下至上层次感更强，传感器标定和工作时便于工作人员一止了然观察和操作。可理解的，在其他的实施例中，所述底架10、侧架、顶架11并不限于板状结构，还可以为杆状结构、框架结构等等。
本实施例中，所述驱动机构2为设于所述右侧板103的外侧面上相应于所述传动机构6的位置处的旋转手轮2，所述旋转手轮2的旋转轴由外至内的穿过所述右侧板103后与所述传动机构6连接。可理解的，在其他的实施例中，所述旋转手轮2可以设置于所述左侧板102上、顶板104上等等。所述驱动机构2还可以为电动驱动机构(例如电机)。

所述传感器装载机构4包括一丝杠副41、一导向组42、一升降板43以及一传感器装载板44，所述丝杠副41的丝杠410的上端与所述从动齿轮63连接，所述丝杠410的下端与所述底架10连接，所述导向组42包括分别位于所述丝杠副41两侧且立设于所述顶架11和底架10之间的导向杆421，所述升降板43具有一中心孔431，所述升降板43通过所述中心孔431套设于所述丝杠副41的丝杠螺母411上以能够随所述丝杠螺母411上下升降，所述升降板43的两端相应于所述导向杆421的位置处设置有与所述导向杆421导向配合的导向孔432。所述传感器装载板44的后端固定于所述升降板43上，前端超出所述 升降板43的前端面，所述传感器装载板44的前端设置有用于装载传感器3并对其限位的装载部45，所述装载部45具有从高度方向贯穿所述装载部45的贯穿孔451，所述秤盘5的上端穿过所述贯穿孔451后与所述传感器3连接。具体的：
所述丝杠410的上端穿过所述顶板104后与所述从动齿轮63的中心处固定连接，所述丝杠410的下端与所述底架10连接(可通过轴承与所述底板101连接)。当从动齿轮63转动时，带动所述丝杠410跟随所述从动齿轮63转动，从而使得所述丝杠螺母411向上或向下移动。
本实施例中，所述导向组42包括两两为一组的四根导向杆421，两组导向杆421分别设于所述丝杠副41的左侧和右侧。四根导向杆421在水平投影上呈与所述升降板43相匹配的矩阵，所述四根导向杆421分别穿设于所述升降板43的四个边角处，且所述四根导向杆421的上端均与所述顶板104连接，下端均与所述底板101连接。四根导向杆421可以更加稳定地对所述升降板43进行导向作用，在不同的实施例中，所述导向杆421的数量可以不同的变化，例如可以采用左右各一根导向杆421进行导向等等。
所述升降板43为矩形板，在所述升降板43相应于四根导向杆421的位置处开设有对应的四个导向孔432，在所述导向孔432内设置有一导向筒422，在所述导向筒422的上端或者下端环设有一法兰423，所述导向筒422穿设于所述升降板43的导向孔432中，通过所述法兰423、螺钉与所述升降板43可拆卸连接。可理解的，所述升降板43的形状并不限于矩形，在不影响其功能的情况下，所述升降板43的形状可以根据需求而定。
所述传感器装载板44为在水平方向上与所述升降板43垂直的矩形板。具体的，所述传感器装载板44的后端相应于所述丝杠410的位置处开设有供所述丝杠410穿过的穿孔441，在所述传感器装载板44的后端相应于所述穿孔441周缘位置处开设有若干间隔设置的盲孔442，在所述升降板43上相应于所述盲孔442的位置处开设有螺孔，在安装所述传感器装载板44时，将若干螺栓一一对应的向下穿过所述盲孔442后，螺锁于对应的螺孔中。
所述装载部45还具有一置于所述传感器装载板44上相应于所述贯穿孔451的位置处的限位部件45a，所述限位部件45a包括后侧挡452、与所述后侧挡452两端连接的左侧挡453及右侧挡454、与所述左侧挡453及右侧挡454的前端连接的前侧挡455；所述限位部件45a还包括设于所述后侧挡452底部且位于所述后侧挡452的前侧边的后侧底板456、设于所述左侧挡453的底部且位于所述左侧挡453的右侧边的左侧底板457、设于所述右侧挡454的底部且位于所述右侧挡454的左侧边的右侧底板458以及设于所述前侧挡 455的底部且位于所述前侧挡455的后侧边的前侧底板(该前侧底板非必须部件)；所述后侧挡452、左侧挡453、右侧挡454及前侧挡455之间的空间形成用于装载所述传感器3的传感器装载腔45b，所述传感器装载腔45b绕所述贯穿孔451周围设置；当所述传感器3置于传感器装载腔45b中后，所述传感器3底面的各边缘分别置于所述后侧底板456、左侧底板457、右侧底板458以及前侧底板上。上述侧挡与对应的侧底板呈L形状，相应侧底板位于相应的侧板的内侧，当所述传感器3置于所述传感器装载腔45b时，各侧底板从底部对所述传感器装载腔45b进行限位，各方向的侧挡从对应的方向对所述传感器3进行限位，防止在标定时所述传感器3移动导致的标定不准确的问题出现。
所述限位部件45a的后侧挡452、左侧挡453、右侧挡454及前侧挡455为一体成型件，通过螺栓螺接于所述传感器装载板44的前端位置处。所述传感器装载板44的前端位于所述贯穿孔451周围的部分形成所述后侧底板456、左侧底板457、右侧底板458以及前侧底板，也即，所述传感器装载板44相应于所述贯穿孔451周围位置处位于所述一体成型件的内侧，又由于所述传感器装载板44位于所述一体成型件的下表面，这样即可通过这样巧妙的位置关系形成所述后侧底板456、左侧底板457、右侧底板458以及前侧底板。采用这样的结构，由于一体成型件的尺寸大于所述贯穿孔451并与传感器3相匹配(所述贯穿孔451与所述传感器3的中心孔31相匹配)，这样使得传感器3放置于所述传感器装载板44的前端上表面后，通过一体成型件对传感器3侧方限位，通过传感器装载板44的上表面对所述传感器3的底部进行限于，可以使限位部件45a的结构更简单，减少各侧底板的制造成本，同时通过可拆卸螺锁方式将限位部件45a固定于所述传感器装载板44前端，增加灵活度，对应于不同尺寸的传感器3，可以更换对应的限位部件45a。可理解的，在其他的实施例中，所述装载部45与所述传感器装载板44呈一体结构，例如直接在所述装载部45的前端开设限位槽，限位槽底面高于所述装载部45底面。而本实施例中，通过螺锁结构使得所述限位部件45a可拆卸的设置于所述传感器装载板44上相应于所述贯穿孔451的位置处。
作为优选的，所述贯穿孔451在水平面的投影上呈U形，其从所述传感器装载板44的前端贯穿所述传感器装载板44以形成一第一开口441；所述限位部件45a的前端相应于所述第一开口441的位置处开设有一第二开口459。相对应的，所述前侧挡455包括与所述左侧挡453的前端连接的左前侧挡4551以及与所述右侧挡454的前端连接的右前侧挡4552；所述前侧底板包括设于所述左前侧挡4551的底部且位于其后侧边的左前侧底板以及设于所述右前侧挡4552的底部且位于其后侧边的右前侧底板，由于所述左前侧挡4551 的长度与所述左侧挡453的宽度一致，右前侧挡4552的长度与所述右侧挡454的宽度一致，因此所述左前侧底板为所述左侧底板457的前端部分，所述右前侧底板为所述右侧底板458的前端部分。所述左前侧挡4551及右前侧挡4552之间的间距、左前侧底板及右前侧底板之间的间距形成所述第二开口459。这样的结构可以增加安装秤盘5的便捷性，提高安装效率，降低安装复杂度。具体在安装时，所述秤盘5的秤杆52可以从第一开口441和与它重叠的第二开口459中放入，所述秤盘5的秤杆52与秤盘本体51可以先连接好之后，使所述秤杆52与所述第一开口441和第二开口459对准，直接向后推动所述秤盘本体51即可使所述秤杆52进入所述贯穿孔451中，为秤盘5的安装带来极大的方便。若采用而封闭性的贯穿孔451，则需要将所述秤杆52从下往上穿入所述贯穿口，然后再需要将秤盘本体51与所述称杆的下端连接好，最后才能使所述秤杆52的上端与所述传感器3连接，这样极为繁琐，且秤盘5具有一定的重量，需要增加人员才能完成安装，延长了安装时间，加大了安装成本。
所述秤盘5包括一秤盘本体51以及立设于所述秤盘本体51的中心的秤杆52，所述秤杆52的上端穿过所述贯穿孔451后通过一可拆卸连接结构7与所述传感器3可拆卸连接。其中：
所述可拆卸连接结构7包括一立设于所述秤杆52上端且向上穿出所述传感器3的中心孔31的轴杆71以及一置于所述传感器3上表面的挡块72；所述轴杆71包括一轴杆本体711以及一设于所述轴杆本体711上端的轴帽712，所述轴帽712的外径大于所述轴杆本体711的外径，所述轴杆本体711的上端以及轴帽712均凸出于所述传感器3的上表面；在所述挡块72上相应于所述轴杆本体711的位置处开设有一U形卡孔721，所述U形卡孔721从所述挡块72的高度方向和一侧方向贯穿所述挡块72，所述U形卡孔721的开口宽度与所述轴杆本体711的外径相匹配，将所述挡块72置于所述传感器3上时，所述U形卡孔721的开口向所述轴杆本体711方向对准以移动所述挡块72，从而使所述轴杆本体711卡入所述U形卡孔721中。本方案中，利用传感器3自身带有的中心孔31来安装秤杆52，无需再在传感器3上添加新的安装孔，保证了传感器3的整体性。秤杆52上端设置轴杆71，轴杆71设计为轴杆本体711以及在其上端设置有轴帽712的结U形卡孔721的上表面。U形卡孔721的设计便于所述挡块72快速卡入所述轴杆本体711上凸于所述传感器3的上端，方便快速安装，同时U形卡孔721使得所述挡块72具有一定弹性，可以增加挡块72与所述轴杆71的配合度。在上升时，被限位于所述U形卡孔721上表面的轴帽712使得轴杆71、秤盘本体51均跟着上升，同时由于载重物向秤盘本体51施加向下压力， 该向下压力传导至轴帽712上，而轴帽712又置于所述传感器3上表面，这样直接将向下压力作用于所述传感器3上，当下降回位时，秤盘本体51置于底板101上，这个时候释放向下压力，这样即完成对传感器3的快速标定。
作为优选的，在所述秤盘本体51的两端分别设置有一手提部511。在所述秤盘本体51上设置有至少一组用于对载重物进行限位的限位组件。本实施例中，所述限位组件为两组，分别为设于所述秤盘本体51的上表面上位于所述秤杆52左侧的左侧限位组件以及设于所述秤盘本体51的上表面上位于所述秤杆52右侧的右侧限位组件。所述左侧限位组件及右侧限位组件均包括呈对角设置的两组限位角码512，其中，左侧限位组件和右侧限位组件中靠近所述秤杆52的四个限位角码512中，每相邻的两个限位角码512可以采用一体成型结构(凸形)，这样可以减少角码数量，减少螺栓使用量。
作为优选的，所述顶板104所在的水平位置低于左右侧架的顶端面，在所述左右侧架的顶端面上还架设有一遮于所述顶板104上方的遮板(图未示出)。
本发明传感器快速定标装置，工作原理如下：通过旋转手轮2旋转产生的动力依次带动联轴器64、减速器61、主动齿轮62、从动齿轮63、丝杠410等零件运动，丝杠410随所述从动齿轮63以旋转带动升降板43上下移动，升降板43通过螺杆拉动秤盘本体51上下移动，传感器3安装在螺杆与挡块72之间承压，秤盘本体51上载重物通过秤盘本体51的上下移动以实现传感器3施压和释压工作。
本发明的传感器快速定标装置与传统标定方式相比，具有以下有益效果：一、将传统技术中的砝码移动、传感器不动的方式改为砝码固定、传感器移动的方式，在标定同一种传感器时，砝码一直放置于秤盘本体上，对这一种传感器的若干个传感器进行快速标定，在当前传感器标定完成时，只需要取下当前已标定的传感器，将下一个待标定的传感器装入传感器装载板的装载部即可进行标定，通过固定砝码而选择通过快速更换待标定传感器的方式省去了多次搬运砝码导致的时间和人力的损耗，节约时间和人力，方便快捷。二、架体结构设计巧妙，能够使得传感器装载机构安装在所述架体上后，保证所述传感器装载板的装载部位于所述秤盘的正上方，合理紧凑的布局使得一切结构位置刚刚好，避免多余空间浪费。三、主/从动齿轮位于顶板上方，减速器、联轴器等机构位于顶板下方靠近安装有旋转手轮的侧板的位置处，使得传动实体部分示于正面，传动驱动隐藏于顶板之下，使得架体整体性更高，所述减速器采用涡轮蜗杆结构减速器，具有锁死功能，动力只能通过旋转手轮来传输给所述传感器装载机构的丝杠410，丝杠410不能反向传递动力给旋转手轮，这样就可以做到秤盘可以停靠在任何高度位置。四、一改传统的传感器在下、加载 物在上的思维，据此设计的传感器装载机构解决这一问题，传感器装载板安装在升降板上，升降板安装在丝杠螺母上，而丝杠410上端与从动齿轮连接，下端可通过轴承固定于底板上，通过这样的联动方式，最终带动所述传感器装载板上、下升降，从而提升装有加载物(砝码)的秤盘上升和下降，完成传感器的标定，设计思路巧妙，从而起到快速标定传感器的作用，提高标定速度和效率，解决人力搬运加载物导致的效率低、人力损耗、标定慢和复杂的问题。五、所述秤杆与传感器的连接十分巧妙，并非传统意义上的螺纹连接，U形贯穿孔使得秤杆放入装载部中十分快捷，在传感器上方置放U形卡孔，在秤杆上端设置具有轴帽的轴杆，并且轴帽外径大于所述U形卡孔的开口宽度，轴杆的外径与U形卡孔的开口宽度相匹配，在安装时，只需要将秤杆放入所述U形贯穿口中，再将传感器的中心孔对准所述轴杆并向下穿设于所述轴杆的上端，置于传感器装载腔中，再将挡块的U形卡孔对准所述轴杆并向该方向卡入，这样在上升时，轴帽下端面被卡于挡块的上表面，使得秤盘随之上升而不掉落，完成传感器快速标定。这种结构，非常方便传感器快装，借助传感器本身具有的中心孔完成传感器快装，保证秤盘随之上升，不破坏传感器的结构。
以上仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
