Description

分体式钻杆支承套
技术领域
本实用新型属于机械加工工装领域,涉及一种对钻具深孔加工工装的改进,具体涉及一种能够方便操作、降低生产成本的分体式钻杆支承套。
背景技术
现有钻具的钻杆支承套为钢质整体式,本体直接和钻杆接触,在钻具产品深孔加工过程中,钻杆旋转且直线进给,造成钻杆支承套严重磨损,每种规格的钻杆支承套只能适合一种钻杆,更换频繁、生产成本大。
发明内容
本实用新型的目的在于克服现有技术中存在的不足而提供一种外套为钢质材料,内衬材料为尼龙的分体式钻杆支承套,能够提高耐磨性,且尼龙衬套磨损后只更换内衬即可,钢质外套可继续使用,大大降低了生产成本。
本实用新型的目的是这样实现的:一种分体式钻杆支承套,包括钢质材料做成的钻杆外套,其特征在于:在钻杆外套中安装有与钻杆相配合的内衬套,钻杆外套与内衬套是分体结构。
所述内衬套的材料为尼龙。
本实用新型的外套为钢质材料,内衬材料为尼龙,能够提高耐磨性,且尼龙衬套磨损后只更换内衬即可,钢质外套可继续使用,大大降低了生产成本。
附图说明
图1为现有钻杆支承套的一体式横向结构剖视图。
图2为现有钻杆支承套的一体式纵向结构剖视图。
图3为本实用新型的分体式横向结构剖视图。
图4为本实用新型的分体式纵向结构剖视图。
具体实施方式
实施例1,如图3、4所示,一种分体式钻杆支承套,包括钢质材料做成的钻杆外套,其特征在于:在钻杆外套中安装有与钻杆相配合的内衬套1,钻杆外套与内衬套1是分体结构。
所述内衬套1的材料为尼龙。

Claims (2)

1.一种分体式钻杆支承套,包括钢质材料做成的钻杆外套,其特征在于:在钻杆外套中安装有与钻杆相配合的内衬套,钻杆外套与内衬套是分体结构。
