Description

一种便于固定工作台的挠度补偿装置 技术领域
本发明属于工作台相关设备技术领域，更具体地说，涉及一种便于固定工作台的挠度补偿装置。
背景技术
随着轨道交通产业的快速发展，轨道交通车体钣金结构件的需求在逐年增加，轨道交通车体钣金结构件的折弯模具作为车体加工技术的关键设备，广泛适用于动车、高铁、地铁等轨道交通车体以及各类车辆制造领域，具有广阔的应用空间。在进行许多轨道交通的零部件生产中，需要使用折弯机进行生产。
折弯机在对板材进行折弯的过程中，往往不可避免的存在自身架构的受力造成滑块产生弹性变形，虽然变形量极其微小，但对于高精度折弯工件而言，被制作件依然容易产生挠度变形，无法保证角度的全长一致性。对于传统的以液压为施力源的折弯机而言，由于油缸的施力不均匀，在折弯过程中，会使工件在长度方向上产生一个挠度，且超长折弯模具也经常用于折弯较短的工件，这样会造成上模仅在下模的中间部位施力，长期使用后，容易造成工作台中间部位下凹，也严重影响了工件的直线度。
为了解决这一问题，一是可以采用增加机身整体重量从而强化机身刚度和强度，但这样增加了设备成本，不符合现代化制作制造业的要求；二是选择挠度补偿工作台，这种方法成本较低，目前国内外的折弯机一般有两种挠度补偿方式：一种是把多台液压缸嵌在工作台立板里的液压挠度补偿；另一种则是由多组加凸楔块组成的机械挠度补偿。对于使用楔块进行机械挠度补偿有专利进行记载，例如中国专利申请号201120271046.9，公告日2012年3月7日的专利文件，公开了一种折弯机的斜楔式挠度补偿装置，该装置包括上盖板和底座，底座上沿长度方向开设矩形槽，矩形槽中安装有下拖板，下拖板上纵向均布安装奇数组斜楔机构，各斜楔机构均由自下而上依次叠装的斜楔Ⅱ和斜楔Ⅰ组成，下拖板上依次叠装矩形垫铁、上拖板，楔块Ⅰ均匀嵌套在上拖板上，上盖板通过螺钉与斜楔Ⅰ固定连接。
另有中国专利申请号201620545340.7，公开日2016年10月26日的专利文件，公开了一种折弯机工作台挠度补偿装置，该装置包括底座，底座上沿纵向设置有矩形槽，矩形槽内设置有若干斜楔，斜楔上表面设置有朝纵向的第一斜面，斜楔上方设置有下表面为第二斜面的圆弧盖板，第一斜面与第二斜面对应；圆弧盖板与底座之间相对矩形槽纵向固定，各斜楔之间设置有空心隔套管；斜楔和空心隔套管之间穿装有拉杆，拉杆为螺纹杆；空心隔套管内壁设置有与螺纹杆对应的螺纹。中国专利申请号为：201811479570.8，公开日为：2019-02-15 的“一种折弯机工作台纵向机械挠度补偿装置及其制作方法”，其包括上斜板和下斜板，上斜板和下斜板均为整体结构且尺寸相一致，其中上斜板的下表面设置有朝纵向的第一斜面，第一斜面的斜率从中间至两端由一个较大的斜率Kj减少到一个较小的斜率Ki，相邻的两第一斜面通过圆弧面衔接，圆弧面的弧度由中间至两端由一个较小的弧度Ri增加到一个较大的弧度Rj；下斜板的上表面设置有与第一斜面对应的第二斜面。但上述补偿装置在进行折弯机工作台的补偿过程中，不能结合工作台的实际情况进行精确补偿。但上述工作台挠度补偿装置不能方便的进行固定调节。

如图5所示，紧固斜块31一端直径较大，另一端直径较小，其整体可设置成圆台状，在安装过程中，紧固斜块31直径较大的一端设置在上侧，直径较小的一端设置在下侧，紧固斜块31中间设置有台阶孔，台阶孔孔径较大的一端，设置在紧固斜块31直径较大的一端；台阶孔直径较小的一端设置在紧固斜块31直径较小的一端。紧固斜块31中间设置台阶孔，通过固定件32与紧固斜块31中的台阶孔进行卡合，对固定件32进行限位，使得固定件32的固定效果更好。通过台阶孔的平台处抵靠紧固螺钉，紧固螺钉与紧固斜块31之间的受力面为台阶孔的平台处，两者之间的结合更加稳定，便于将紧固斜块31置入底座1的滑槽中，在使用过程中，先将紧固斜块31与紧固螺钉套接放置好，将紧固斜块31从滑槽一端的圆形或方形孔放入，然后拖动紧固螺钉带动紧固斜块31，将紧固斜块31拖至需要的位置。
紧固斜块31上端直径较大，下端直径较小，为制造的便利，可将紧固斜块31设置成圆台状，在紧固斜块31直径较大的一端加工直径较大的孔，在紧固斜块31直径较小的一端加工直径较小的孔，两端的孔整体呈台阶孔的状态，通过台阶孔对固定件32进行限位。紧固斜块31外侧呈现变径的状态，上端直径大，下端直径小，通过顶压件33的顶压，两边顶压件33向中间施力，对紧固斜块31进行受力分解，紧固斜块31受到向内和向上的力，紧固斜块31受到顶压件33向内的力，使得紧固斜块31的位置稳定，不易发生晃动，紧固斜块31受到向上的力，使得紧固斜块31向固定件32施加向上的力，固定件32向紧固斜块31产生反作用力，使得固定件32与紧固斜块31之间的连接稳定，在进行工作台挠度补偿装置的安装过程中，固定件32与下端的位置不好定位，往往需要进行固定件32的微调，通过两端顶压件33沿着底座1宽度方向的移动，可实现紧固斜块31带动固定件32沿着底座1宽度进行移动，实现固定件32位置的微调，固定件32能够更容易与底座1下部的部件进行结合安装。

实施例3
本实施例在实施例1和实施例2的基础上还包括罩壳8和标尺9，罩壳8在垂直方向分为两部分，分别与底座1和盖板2相接，标尺9连接垂直方向的两部分罩壳8。在下斜块运动的过程中，盖板2与底座1的不同位置的距离都会发生变化，通过在底座1和盖板2外部设置罩壳8，罩壳8之间使用标尺9相接，就能够直观的测出工作台不同位置的实际补偿量，能够更加精准的实现工作台的挠度补偿。
实施例4
本实施例在实施例1-3的基础上，还在于下斜块21为分体式，由多个下斜块21组成，下斜块21的宽度可与凹槽的宽度相当，但下斜块21与凹槽之间为间隙配合的方式，使得下斜块21在后续能够进行运动，并且不影响上斜块22的调节。相邻下斜块21之间通过连接块23连接，下斜块21与连接块23之间通过螺钉连接，能够方便的实现下斜块21与连接块23之间的装卸。通过连接块23与下斜块21进行连接，将多个下斜块21连接成整体放置在凹槽中，而上斜块22与下斜块21对应设置，能够方便的根据不同的需求进行工作台的补偿。连接块23与底座1之间通过螺钉相接，连接块23中间设置滑槽，螺钉可在滑槽中滑动。下斜块21与连接块23之间通过螺钉相接，能够实现不同斜率的下斜块21的更换，进而实现不同的补偿需求，连接块23中间的螺钉可在滑槽中滑动，则下斜块21在移动过程中，连接块23也在移动，可保证连接块23不会发生偏移，同时实现连接块23和下斜块21的滑动。
