Description

一种瓷砖平面度检测装置 技术领域
本发明涉及建筑检测技术领域,特别是涉及一种瓷砖平面度检测装置。
背景技术
随着人们生活水平的提高,对居住条件的整洁性以及易打理性提出了较高的要求。在室内装修过程中,对地面和部分墙面进行瓷砖铺设日益成为一项不可或缺的施工项目。
为了确保良好的施工效果,需要确保瓷砖具有合格平面度误差。然而,随着瓷砖的规格尺寸的日益增大,且受生产、运输、存放等多种因素影响,其平面度指标较难控制。在实际施工过程中,当相邻瓷砖的边沿平面度误差稍大时,相邻瓷砖之间的接缝处会产生较明显的高低不平感,影响整体的美观效果。为了解决这一问题,较为常见为方案为:在进行正式施工前,采用抽检的方式对预铺设批次的瓷砖进行检测,当不合格率超过标准值时,即判定整批次不合格,需对瓷砖进行整批次更换。然而,目前为止,尚没有合适的检测装置用于执行上述抽检操作。在现有技术中,操作人员均借助于靠板与塞尺相互配合来对抽检到的瓷砖进行水平度检测。已知,在检测过程中需要对靠板进行旋转、移位,极易发生漏检现象,且上述操作过程费时费力,导致检测效率低下,因而,亟待技术人员解决上述问题。
发明内容
本发明要解决的技术问题是提供一种结构设计简单,检测效率高,且检测结果准确性高的瓷砖平面度检测装置。
为了解决上述技术问题,本发明涉及了一种瓷砖平面度检测装置,其包括机架、用来放置待检测瓷砖的置物板、检测组件以及直线动力元件。机架包括基础底板以及垂直于该基础底板固定的承力件构成。置物 板平放于基础底板上。直线动力元件固定于承力件上,且驱动检测组件整体沿着上下方向进行移动。检测组件包括检测基准板和千分表。检测基准板布置于基础底板的正上方,且相互平行。千分表的数量设置为多个,垂直地穿设、固定于检测基准板。
作为本发明技术方案的进一步改进,在置物板的底面四角均设置有调平组件。调平组件由调节螺栓和锁紧螺母构成。调节螺栓反穿于置物板上,相应地,在置物板上开设有与调节螺栓相适配的螺纹孔。锁紧螺母套设于调节螺栓上,且始终顶靠于置物板的底平面。
作为本发明技术方案的进一步改进,上述瓷砖平面度检测装置还包括导向装置。导向装置包括导向杆以及导套。在承力件上开设有穿越孔。导套套设、固定于穿越孔内。导向杆穿越导套,且其底端与检测基础板垂直固定。
作为本发明技术方案的更进一步改进,导向装置的数量设置为2套,对称地布置于直线动力元件的左、右侧。
作为本发明技术方案的进一步改进,在检测基准板的底面四角均设置有限位螺栓。限位螺栓反穿于检测基准板上,相应地,在检测基准板上开设有与限位螺栓相适配的螺纹孔。
作为本发明技术方案的进一步改进,直线动力元件为液压缸、气缸或直线电机中的任一种。
在本发明所公开的技术方案中,由检测基准板拖动多个处于“调零”状态的千分表相对于待检测瓷砖进行同步靠近,根据各千分表读数的差值即可推得瓷砖的平面度数据,这样一来,相较于传统纯人工检测方式,具有较高的检测效率以及检测精度,且极大地了降低了操作人员的劳动强度。
附图说明

具体实施方式
在本发明的描述中,需要理解的是,术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
下面结合具体实施例,对本发明的内容做进一步的详细说明,图1示出了本发明中瓷砖平面度检测装置的立体示意图,其主要由机架1、用来放置待检测瓷砖的置物板2、检测组件3以及气压缸4等几部分构成。其中,机架1包括基础底板11以及垂直于该基础底板11固定的承力件12构成。置物板2平放于基础底板11上。气压缸4用来驱动检测组件3整体沿着上下方向进行移动。检测组件3包括检测基准板31和千分表32。检测基准板31布置于基础底板11的正上方,且相互平行。气压缸4固定于承力件12上,且布置于检测基准板31的正上方,其输出端与检测基准板31相固定。千分表32的数量设置为多个(根据预检测 瓷砖的实际外形进行均布),垂直地穿设、固定于检测基准板31。在具体执行瓷砖平面度检测的过程中,由检测基准板31拖动上述多个处于“调零”状态的千分表32相对于待检测瓷砖进行同步靠近,根据各千分表32读数的差值即可推得瓷砖的平面度数据,这样一来,相较于传统纯人工检测方式,具有较高的检测效率以及检测精度,且极大地了降低了操作人员的劳动强度。
在此需要说明一点,用来驱动检测基准板31进行上下位移运动的直线动力元件,除了采用上述的气压缸4,还可以根据具体情况选择液压缸或直线电机。
作为上述瓷砖平面度检测装置的进一步优化,还可以在置物板2的底面四角均设置有调平组件5(如图1中所示),以便于在进行实际检测前对置物板2的水平状态进行调整,以保证其与上述各千分表32的测量头始终保持垂直状态,确保检测结果的准确性。在此需要说明的是,调平组件5优选由调节螺栓51和锁紧螺母52构成。调节螺栓51反穿于置物板2上,相应地,在置物板2上开设有与调节螺栓51相适配的螺纹孔。锁紧螺母52套设于调节螺栓51上,且始终顶靠于置物板2的底平面(如图3中所示)。
出于确保检测基准板31在进行上下位移运动进程中其自身水平度方面考虑,还可以额外设置有导向装置6。导向装置6的具体方式推荐参照如下方案进行:导向装置6包括导向杆61以及导套62。相应地,在承力件12上开设有穿越孔,以供导套62穿越、固定。导向杆61穿越导套62,且其底端与检测基础板31垂直固定(如图2中所示)。
再者,作为上述技术方案的进一步优化,上述导向装置6的数量设置为2套,对称地布置于直线动力元件的左、右侧(如图1中所示),从而尽可能地确保检测基础板31在进行上下位移运动过程中其自身受力的均衡性,确保直线动力元件的使用寿命。
已知,当检测基础板31相对于承力件12发生上下位移运动的过程中,导向杆61与导套62不可避免地会发生磨损现象,从而影响两者的 配合精度,进而不利于检测基准板31水平状态的保持。为此,可以在导套62的内腔开设有多条环形石墨镶嵌槽621,其沿其轴向进行均布(如图4、5中所示)。利于石墨的自润滑特性来有效地降低导套62和导向杆61之间的相对摩擦系数,降低磨损速率。
最后,需要说明的是,还可以在检测基准板31的底面四角均设置有限位螺栓311。限位螺栓311反穿于检测基准板31上,相应地,在检测基准板31上开设有与限位螺栓311相适配的螺纹孔(如图2中所示)。这样一来,从而可有效地防止当直线动力元件向下位移运动超标而导致的千分尺32受损现象,确保瓷砖平面度检测装置的使用安全性。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
