Description

长度测量装置
技术领域
本发明涉及一种根据权利要求1的前序部分的长度测量装置。
背景技术
例如在文件EP 0 418 212 A2中说明了一种这样的长度测量装置。这样的长度测量装置被称为封装的长度测量装置且其用于可彼此相对移动的两个对象的位置测量。封装的长度测量装置尤其在加工机器中被用于测量工具关于待加工的工件的相对运动。
由文件EP 0 418 212 A2中已知的长度测量装置由空心型材(Hohlprofil)构成，其保护固定在其中的标尺免受环境影响。空心型材的端侧的端部相应利用端部件(Endstueck)来封闭，端部件还构造成用于将空心型材安装在待测量的对象中的一个处。端部件具有插入件(Einsatzteil)，端部件以其沉入空心型材的光孔中。在端部件处布置有密封件，其引起端部件与空心型材之间的密封。为了容纳密封件在插入件中存在槽。
代替在周缘上作用的密封，在长度测量装置中还使用撞击密封(Stoßdichtung)的方案。对此的示例是在文件DE 34 12 879 A1中。在此，承载标尺的空心型材的端侧的端部借助于端部件来封闭且在空心型材的端侧的端部与安放于其上的端部件之间插入密封件。
发明内容
本发明目的在于提供一种长度测量装置，其在端侧能够简单且有效地密封且利用其使可复制的位置测量成为可能。
该目的根据本发明通过权利要求1的特征来实现。
根据本发明，长度测量装置包括在纵向上延伸的空心型材，在其内腔中布置有带有测量刻度(Messteilung)的标尺。空心型材的至少一个端侧的端部利用端部件来封闭，其位置固定地固定在空心型材处。端部件承载用于密封空心型材的密封元件。该密封元件以其周缘面密封地贴靠在空心型材的内侧处。密封元件的横截面至少很大程度上相应于空心型材的端侧的开口的横截面。密封元件即构造成使得其填充和桥接空心型材的净宽，其尤其具有片状的形式。这具有该优点，即密封元件仅须在空心型材的面处密封，其中，端部件相对于用于密封空心型材的内腔的密封元件的密封不是强制必需的。
为了端部件相对于空心型材的简单对准，其具有沉入区域(Eintauchbereich)，端部件以其沉入空心型材的内腔中。密封元件在此布置在沉入区域的指到空心型材中的端部处。
当密封元件在端部件处安装成使得其可相对于端部件横向于空心型材的纵向移动或移位时，是特别有利的。可移动性一方面允许通过推动将密封元件安装在端部件处，由此使组件端部件和密封元件能够简单地预装配。以密封元件相对于端部件横向于纵向的浮动支承的形式的可移动性另一方面还确保，密封元件在端部件的所有安装位置中自行在空心型材中定心，由此一方面确保良好的密封而另一方面也不会不利地影响长度测量装置的测量精度，因为不通过密封元件施加不允许的力到承载标尺的空心型材上。因为密封元件桥接空心型材的净宽且可横向于纵向移动地安装在端部件处，密封元件在力在侧面作用于其上的情况下被挤压到空心型材的相对而置的面处，由此确保自定心。
当密封元件仅在相对于空心型材的内表面密封地作用的区域处由相对挠性的且因此柔性的材料来构造时，特别确保可靠的密封和自定心。密封元件的中间区域(其填充空心型材的净宽)相比之下由更无挠性的材料制成。
以特别有利的方式，端部件不仅构造成用于在端侧封闭空心型材，而且用于将空心型材安装在待测量的对象处。对此，端部件可具有用于容纳螺钉或者螺栓的孔，通过螺钉或者螺栓来承载带有固定在其处的空心型材的端部件。代替孔，以已知的方式在端部件处还可布置有角、螺栓或者球体，利用其可将空心型材固定在待测量的对象处。
当应在恶劣的环境中应用该长度测量装置时，在内腔中产生超压。为了使这成为可能，在端部件处设置有压缩空气接口，经由其可将压缩空气导引到空心型材的内腔中。
密封元件以有利的方式布置和构造成使得从压缩空气接口导入的压缩空气冲击到密封元件上且在那里被转向。转向的压缩空气在密封元件的指到空心型材的内腔中的排出口处排出。优选地，密封元件在所导入的压缩空气冲击的地点与排出口之间具有用于压缩空气的引导通道。

具体实施方式
根据光电的长度测量装置详细地来阐述本发明。该长度测量装置由部件标尺1和探测单元2构成，其在纵向X上可彼此相对移动。为了测量在纵向X上可彼此相对移动的两个对象的位置，将标尺1固定到这些对象中的一个处而将探测单元2固定到这两个对象中的另一个处。探测单元2在位置测量时探测标尺1的测量刻度11且由此形成位置测量值。测量刻度11可构造为带有一连串间隔相同的记号的增量轨迹(Inkrementalspur)、构造为带有在纵向X上相继布置的绝对编码(也称伪随机码)的单轨迹的绝对轨迹(Absolutspur)或者为多轨迹的绝对轨迹。本发明不限于光电探测原理，记号也可设计成可电感地、磁性地或者电容地探测。
标尺1受保护地安置在在纵向X上延伸的空心型材3中。通过其例如尤其通过粘合剂固定在U形空心型材3的边腿的内侧处，标尺1固定在空心型材3处。空心型材3在纵向X上伸延地具有裂口状的开口，其被顶篷状布置的密封唇4遮盖。剑形带动件21伸过密封唇4，探测单元2固定在剑形带动件21处。在空心型材3之外，在带动件21处布置有装配元件22，其设计用于例如通过拧紧被固定在这两个待测量的对象中的一个处。
空心型材3的两个端侧的端部相应利用端部件5来封闭，其中，仅示出其中的一个。端部件5位置固定地固定在空心型材3处。在所示的实施例中，端部件5在空心型材3处的固定借助于夹持块(Klemmstueck)6实现。将夹持块6与端部件5拧紧，由此施加力到空心型材3的布置在夹持块6与端部件5之间的截段31上，该力将空心型材3的截段31和因此空心型材3自身与端部件5位置固定地相连接。截段31在图6中示出。
端部件5构造成用于安装在待测量的对象中的一个处。对此，端部件5具有用于紧固螺钉的或者螺栓的孔53。
在端部件5处布置有密封元件7，其密封空心型材3的端侧的端部。端部件5具有沉入区域51，端部件5以其沉入空心型材3的内腔中。密封元件7布置在端部件5的沉入区域51的指到空心型材3中的端部处。如尤其从图2可见，密封元件7片状地来构造且以其周缘面71密封地贴靠在空心型材3的内侧32处。
空心型材3构造成U形且具有两个彼此平行伸延的边腿和连接边腿的底部。裂口状的开口与底部相对而置且由两个模制空心型材3的边腿的突起来限制。端部件5的沉入区域51的横截面与空心型材3的横截面匹配成使得这两个边腿的、底部的和突起的内表面贴靠在沉入区域51的侧面处。端部件5横向于纵向X的位置因此通过空心型材3的内表面形状配合地来规定。
在图3和图4中透视性地示出密封元件7。图3显示指到空心型材3的内腔中的侧面而图4显示指向端部件5的方向的侧面。密封元件7这样安装在端部件5处，使得其能够横向于纵向X相对于端部件5移动。对此，端部件5和密封元件7在彼此相对而置的面处具有相应的连接元件52和72，其一方面将密封元件7在纵向X上固定在端部件5处而另一方面允许密封元件7横向于此的可移动性。在该实施例中，设置在端部件5处的连接元件52是T形槽，T形的突起作为密封元件7的连接元件72接合到其中。这两个连接元件52和72(即T形槽和T形突起)形成横向于纵向X起作用的引导部。该引导部用于密封元件7在端部件5处的简单装配，如在图5中所示。密封元件7在端部件5处的安装通过在箭头方向上将密封元件7的T形突起插入端部件5的T形槽中实现。
在图6中为了进一步说明本发明示出另外的装配状态。利用安装在其处的密封元件7在纵向X上将端部件5的沉入区域51插入空心型材3的端侧的开口中且将端部件5位置固定地固定在空心型材3处，例如借助于夹持块6。如已实施的和在图2中所示的那样，密封元件7是片状的且具有外轮廓，其与空心型材3的内轮廓这样相匹配，使得其以其周缘面71密封地贴靠在空心型材3的内侧32处。密封元件7这样安装在端部件5处，使得其也在端部件5装配在空心型材3处期间可横向于纵向X相对于端部件5移动地支撑在其处且因此最佳地匹配当前的位置和空心型材3的内轮廓的尺寸(通过其可以说在那里浮入)。密封元件7的片状设计和在端部件5处端侧的浮动的布置具有该优点，即装配公差和制造公差不负面地影响密封性。
如在图2中所示，空心型材3具有矩形的横截面、亦即带有底部(突起和被密封唇4遮盖的裂口与其相对而置)以及带有两个彼此相对而置的侧壁。密封元件7的片状形式相应于空心型材3的该内轮廓或横截面。端部件5的沉入区域51在空心型材3中横向于纵向X的位置还取决于沉入区域51的面的加工精度，其在插入时与空心型材3的内轮廓相对应。由于密封元件7在端部件5处的浮动支承，密封元件7横向于纵向X的位置不由沉入区域51的位置来确定。密封元件7由于相应彼此相对而置的周缘面71(其与空心型材3的彼此相对而置的内侧32共同作用)在空心型材4中自动定心成使得在全部侧引起最佳的密封。端部件5与密封元件7之间的连接使密封元件7在横向于纵向X的方向上相对端部件5的平衡运动成为可能，其例如为大约0.5mm。
当空心型材3借助于端部件5实现装配在待测量的对象中的一个处时，片状密封元件7的自定心功能还具有特别的优点。通过端部件5在待测量的对象处的固定，端部件5相对于空心型材3的位置即可以改变。由于密封元件7在端部件5处的浮动支承，该移位对密封效果没有影响。
封装的长度测量装置经常被应用在机床处，其用于工件的切削加工。为了防止冷却液或者切屑侵入长度测量装置的内腔中，在空心型材3的内腔中产生超压。对此，在端部件5处设置有压缩空气接口54，以使能够联接到压缩空气源处。该压缩空气接口54和接下来所阐述的结构在图7中示出。引入端部件5中的压缩空气又在端部件5的排出口55排出。片状的密封元件7现在布置和构造成使得从压缩空气接口54出发所引入的压缩空气冲击到密封元件7上。密封元件7即具有面，其对于所引入的压缩空气用作缓冲面。密封元件7此外具有用于压缩空气的指到空心型材3的内腔中的排出口74。密封元件7在端部件5的排出口55与密封元件7的排出口74之间具有用于压缩空气的引导通道73。排出口55即相对于排出口74横向于纵向X偏移地来布置。
图8至图10显示密封元件700的第二实施例。与第一实施例相一致，该密封元件700片状地来构造且以其周缘面710在空心型材3的内侧32处密封空心型材3的端侧的端部。密封元件700此外还具有连接元件720，以能够被这样固定在端部件5处，使得其一方面在纵向X上位置固定地固定在其处而另一方面使横向于纵向X的平衡运动成为可能。不同于第一实施例，在密封元件700处在指到空心型材3的内腔中侧面上设置有用于压缩空气的引导通道730且引导通道730以排出口740(其使引入空心型材3的内腔中的压缩空气指向密封唇4的方向)终止。
弹性体(例如NBR、EPDM或者ACM)特别适合作为用于密封元件7、700的材料。连接元件72、720和引导通道73、730优选地通过喷注模制到片状密封元件7、700处。
为了良好密封，至少密封元件7、700的指向空心型材3的内侧32的周缘面71、710由柔性好的软的塑料、尤其弹性体构成。密封元件7、700可由唯一的材料构成、尤其由弹性体制造为注塑件。备选地，密封元件7、700可由两个不同的材料构成、即为了密封目的的软的材料和不需要为了密封目的的较硬的材料。通过密封元件7、700的不用于密封目的的区域由较硬的塑料、例如热塑性材料(如聚丙烯)制成，该制造可以以两成分-注塑工艺实现。
