【技术实现步骤摘要】
潜油电泵内孔定位型压轴瓦工具
本技术属于潜油电泵轴瓦安装领域,尤其是涉及潜油电泵内孔定位型压轴瓦工具。
技术介绍
潜油电泵设计中,径向轴承均采用轴瓦与轴形成对磨付的滑动轴承结构,目前潜油泵轴瓦孔有两种结构形式,一种是较短的轴瓦孔结构,也就是轴瓦孔为浅孔结构;另一种是轴瓦孔设置在基座较深处,也就是轴瓦孔为深孔设计,基座在该轴瓦孔外侧设有和该轴瓦孔正对的内孔,现实操作中,对这两种总轴瓦孔压瓦均采用冷装压瓦工艺,冷装压瓦工艺是常温下,将存在过嬴配合的轴瓦基座(一般为钢制潜油电泵中各种设备头座零部件)内孔与轴瓦(一般为铜基合金或者硬质合金材料)外壁通过压力,使轴瓦外径变形或基座内孔变形后将轴瓦压入基座孔内。由于轴瓦材料采用硬度较高、抗磨性较好、易碎的硬质合金材料,并且在该冷装压瓦工艺执行过程中经常出现由于轴瓦与基座孔对中性不好,而将轴瓦压裂损坏的现象。
技术实现思路
有鉴于此,本技术旨在针对较深轴瓦孔提出潜油电泵内孔定位型压轴瓦工具,以解决向该较深基座轴瓦孔压装轴瓦时因对中不好产生的轴瓦压裂现象。为达到上述目的,本技术的技术方案是这样实现的:潜油电泵内孔定位型压轴瓦工具,包括圆柱状压装杆,该圆柱状压装杆包括压杆定位部及该压杆定位部一端连接的轴瓦定位部,所述压杆定位部和轴瓦定位部同轴设置,所述压杆定位部直径和潜油电泵内正对轴瓦安装孔开设的内孔孔径对应设置,该压杆定位部长度大于潜油电泵该内孔长度,所述轴瓦定位部直径和待压装轴瓦内径设置。进一步的,所述压杆定位部和轴瓦定位部间设有过渡部,过渡部为圆柱状,过渡部直径介于压杆定位部和轴瓦定位部直径间。进一步的,所述轴瓦定位部长度 ...
