Abstract

本发明公开了一种阀体清洗治具，包括底板，还包括至少一块垂直固定在底板上方的限位块，以及至少一根设置在底板上方、与限位块垂直且能够向限位块滑动的定位杆，定位杆上固定连接有与其垂直的夹紧块，夹紧块至少部分为圆弧形，且夹紧块的最大半径大于夹紧块的中心与底板的距离。将阀体置于限位块和定位杆之间且一侧抵在限位块上，向限位块方向滑动定位杆使其顶住阀体的另一侧，旋转夹紧块，使其与底板接触且产生弹性变形，此时夹紧块在摩擦力的作用下无法水平移动，实现对阀体的夹紧。这种夹具，结构简单，适合多种阀体的定位和夹紧，而且操作简单不繁琐，有利于提高生产效率。

Description

一种阀体清洗治具
技术领域
本发明涉及一种治具，尤其是阀体清洗的治具。
背景技术
液压阀在经过长期使用后，由于其内部机构复杂，将会形成较多的污垢，通常情况下对阀体的清洗需要对阀体定位并且夹紧，当清洗的阀体数量较少还能勉强应付，但是，因为液压阀是机器的主要零件之一，数量多且种类繁杂，如果每次清洗要设计专门的工装夹具，在对阀体进行定位夹紧，大量消耗了人力和物力，不利于批量生产。
发明内容
本发明要解决的技术问题是提供简单装夹的阀体清洗治具。
为解决上述问题，本发明提供了一种阀体清洗治具，包括底板，还包括至少一块垂直固定在所述底板上方的限位块，以及至少一根设置在所述底板上方、与所述限位块垂直且能够向所述限位块滑动的定位杆，所述定位杆上固定连接有与其垂直的夹紧块，所述夹紧块至少部分为圆弧形，且所述夹紧块的最大半径大于所述夹紧块的中心与所述底板的距离。
作为本发明的进一步改进，所述夹紧块为腰形。
作为本发明的进一步改进，所述所述底板上方还垂直固定有支撑块，所述支撑块上设有与所述底板垂直且与所述限位块平行的通孔，所述定位杆穿过所述通孔且可转动。
作为本发明的进一步改进，所述限位块为两块，且每块限位块均设有与之对应的定位杆以及支撑块。
本发明的有益效果在于，将阀体置于限位块和定位杆之间且一侧抵在限位块上，向限位块方向滑动定位杆使其顶住阀体的另一侧，旋转夹紧块，使其与底板接触且产生弹性变形，此时夹紧块在摩擦力的作用下无法水平移动，实现对阀体的夹紧。
附图说明
图1为本发明的结构示意图；
其中：2-支撑块；4-定位杆；6-底板；8-限位块；10-夹紧块。
具体实施方式
下面结合附图对本发明做进一步详细说明。
如图1所示，本发明提供了一种阀体清洗治具，包括底板6，还包括至少一块垂直固定在底板6上方的限位块8，以及至少一根设置在底板6上方、与限位块8垂直且能够向限位块8滑动的定位杆4，定位杆4上固定连接有与其垂直的夹紧块10，夹紧块10至少部分为圆弧形，且夹紧块10的最大半径大于夹紧块10的中心与底板6的距离。
将阀体置于限位块8和定位杆4之间且一侧抵在限位块8上，向限位块8方向滑动定位杆4使其顶住阀体的另一侧，旋转夹紧块10，使其与底板6接触且产生弹性变形，此时夹紧块10在摩擦力的作用下无法水平移动，实现对阀体的夹紧。这种夹具，结构简单，适合多种阀体的定位和夹紧，而且操作简单不繁琐，有利于提高生产效率。
进一步的，夹紧块10为腰形，旋转时，夹紧块10的圆弧面与底板6接触，发生弹性变形，产生阻止定位杆4水平移动的摩擦力。
进一步的，底板6上方还垂直固定有支撑块2，支撑块2上设有与底板6垂直且与限位块8平行的通孔，定位杆4穿过通孔且可转动。支撑块2能垂直方向固定住定位杆4，使其不会产生垂直方向的位移。
进一步的，限位块8为两块，且每块限位块8均设有与之对应的定位杆4以及支撑块2。增加了夹紧件的数量，提高了夹紧效果。
以上依据本发明的理想实施例为启示，通过上述的说明内容，相关人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定技术性范围。
