Description

—种筒件加工夹具
技术领域
[0001] 本发明涉及夹具技术领域,具体涉及一种筒件加工夹具。
背景技术
[0002] 筒类零件通常形状精度和位置精度要求较高,并且孔壁较薄的套筒类零件在加工 中因受夹紧力、切削力、切削热等作用后产生变形,需要在保证主要表面的位置精度的同时 还要防止变形,现有技术中通过卡盘等对筒件进行夹持时,常常由于夹紧力使筒件表面产 生变形,完成加工后从夹具上取下工件,变形回复导致加工不合格。
发明内容
[0003] 本发明的目的在于克服现有技术的不足,提供一种筒件加工夹具,夹持变形小,加 工质量高。
[0004] 本发明的目的是通过以下技术方案来实现的: 一种筒件加工夹具,它包括底座,所述底座中心设有环形的芯轴,底座上设有至少两个 气缸,所述气缸的靠近芯轴的一端的活塞杆上设有V形块,所述芯轴沿圆周方向均匀开设有 至少九个通孔,所述通孔内设有支撑钉,底座中心还开设有螺纹孔,所述螺纹孔内设有可调 螺杆,所述可调螺杆的上部位于芯轴内,可调螺杆上设有锥形块。
[0005] 所述的锥形块的顶面直径大于锥形块的底面直径,所述芯轴的内径大于锥形块的 顶面直径。
[0006] 所述的支撑钉的一端接触锥形块,支撑钉的另一端设有垫片。
[0007] 所述的锥形块和可调螺杆一体成型。
[0008] 所述的锥形块上设有旋钮。
[0009] 本发明的有益效果是:采用V形块对零件进行夹持,通过芯轴和支撑钉对筒件进行 内部支撑和定位,减小了夹具和工件的接触面积,减小了变形,提高了加工质量;采用气缸 驱动V形块,夹紧快速。
附图说明
[0010] 图1为本发明结构示意图; 图2为图1的A-A剖视图; 图中,1-底座,2-芯轴,3-气缸,4-V形块,5-支撑钉,6-螺纹孔,7-可调螺杆,8-锥形块, 9_旋钮。
具体实施方式
[0011] 下面结合具体实施例进一步详细描述本发明的技术方案,但本发明的保护范围不 局限于以下所述。
[0012] 如图1、2所示,一种筒件加工夹具,它包括底座1,底座1中心设有环形的芯轴2,底 座1上设有至少两个气缸3,气缸3的靠近芯轴2的一端的活塞杆上设有V形块4,芯轴2沿圆周 方向均匀开设有至少九个通孔,通孔内设有支撑钉5,底座1中心还开设有螺纹孔6,螺纹孔6 内设有可调螺杆7,可调螺杆7的上部位于芯轴2内,可调螺杆7上设有和可调螺杆7—体成型 的锥形块8,支撑钉5的一端接触锥形块8,支撑钉5的另一端设有垫片;锥形块8的顶面直径 大于锥形块8的底面直径,芯轴2的内径大于锥形块8的顶面直径。它还包括旋钮9,旋钮9设 于锥形块8上方。
[0013] 加工时,将工件套设于芯轴2外,调节旋钮9使可调螺杆7向下移动,锥形块8向下移 动,锥形块8向下移动、位于支撑钉5所在平面的锥形块8的直径逐渐增大,由于锥形块8表面 和支撑钉5接触,因此支撑钉5受到锥形块8的推力从而向外侧移动,直到支撑钉5上的垫片 和工件内壁接触,完成对工件的定心和内支撑。
[0014]最后通过驱动气缸3的活塞杆移动,v形块4随之移动,直至夹紧工件,即可完成对 工件的夹持。
[0015]以上所述仅是本发明的优选实施方式,应当理解本发明并非局限于本文所披露的 形式,不应看作是对其他实施例的排除,而可用于各种其他组合、修改和环境,并能够在本 ^所述构想范围内,通P上述教导或相关领域的技术或知识进行改动。而本领域人员所进 行的改动和变化不脱离本发明的精神和范围,则都应在本发明所附权利要求的保护范围 内。
