【技术实现步骤摘要】
一种薄壁零件检测用定位工装
本技术涉及一种薄壁零件检测用定位工装。
技术介绍
零件在完成加工后一般都需要对其尺寸进行检测,以确保零件的加工精度。在对零件尺寸进行检测时,一般都需要使用定位工装将零件固定,但是,现有的定位工装在对其进行固定时的操作较为繁琐,且夹持零件的稳定性较差。
技术实现思路
本技术的目的在于提供一种薄壁零件检测用定位工装,其结构合理,能有效的对薄壁零件进行固定,以便对薄壁零件上U形槽的尺寸进行检测。为实现上述目的,本技术的技术方案是设计一种薄壁零件检测用定位工装,所述薄壁零件呈圆弧形状,该薄壁零件的外缘处沿周向设有若干U形槽;所述薄壁零件检测工装包括底座和环形压板,所述环形压板位于底座上方,该环形压板与底座之间形成有压紧间隙,且该环形压板上沿周向设有若干通孔,所述底座呈圆盘状,该底座顶面设有与若干通孔一一对应的若干容置槽,各容置槽槽底设有螺纹孔,且各容置槽中设有弹簧,该弹簧一端抵于环形压板底面,另一端抵于容置槽槽底,所述通孔中穿设有双头螺钉,该双头螺钉的下端穿过弹簧与螺纹孔连接,且该双头螺钉的上端连接有蝶型螺母。优选的,所述环形压板底面设有一圈橡胶垫。优选的,所述底座中心处设有吊耳。本技术的工作原理为:装夹时,拧松蝶型螺母,使环形压板受弹簧的弹性恢复力作用而抬起,然后将薄壁零件平放于压紧间隙中,然后拧紧蝶型螺母,使环形压板克服弹簧的弹性恢复力并将薄壁零件压紧;并且,通过在环形压板底面设置一圈橡胶垫,由橡胶垫接触薄壁零件,有效的避免了损伤薄壁零件;另外,由于薄壁零件的外形较大,故在底座中心处设置吊耳,便于吊运装夹好薄壁零件的定位工装。本技术的有益效 ...
