The utility model relates to a combined cutting tool for internal thread processing. The utility model comprises a cutter rod and a blade. The cutter rod is composed of a cutter handle and a cutter head. The cutter handle is fixed on the cutter table of a machine tool, and the cutter head drives the cutter rod to move. A boring cutter and a thread comb are fixed on the cutter head. The bottom hole of the workpiece is first processed by the boring cutter, and then the thread comb is used to process the thread. The hole knife and the thread comb are arranged on the knife head at 180 degrees, and the edges of the boring knife and the thread comb are prominent in the outer circumference of the knife head; the boring knife is located at the upper part of the knife head, and the thread comb is located at the lower part of the knife head. The utility model has the advantages that the structure design is reasonable, the inner thread processing of the casing coupling can be completed by using a cutter rod, and the machining process does not need to replace the cutter rod, thus improving the production efficiency and ensuring the thread processing quality.
【技术实现步骤摘要】
一种内螺纹加工组合刀具
本技术涉及一种螺纹加工刀具,尤其是涉及一种内螺纹加工组合刀具,属于机械加工组合刀具
技术介绍
石油开发过程中大量使用油套管,油套管是通过接箍螺纹依次连接下入井筒内。目前,油套管接箍的加工方式大多采用多工位、多种刀杆的加工方式,导致因换刀时间长降低加工生产效率。
技术实现思路
为了克服现有油套管接箍的加工方式采用多工位、多种刀杆的加工方式,导致因为换刀时间长降低加工生产效率的不足,本技术提供一种内螺纹加工组合刀具。本技术解决其技术问题所采用的技术方案是:一种内螺纹加工组合刀具,包括刀杆、刀片,刀杆由刀柄和刀头组成,刀柄固定安装在机床的刀台上,刀台带动刀杆移动,所述刀头上固定安装有镗孔刀和螺纹梳刀;先由所述镗孔刀加工工件的螺纹底孔,再由所述螺纹梳刀加工螺纹。进一步,所述镗孔刀和螺纹梳刀呈180°安装在所述刀头上,所述镗孔刀、螺纹梳刀的刃部突出于所述刀头的外圆周;所述镗孔刀位于所述刀头的上部,所述螺纹梳刀位于所述刀头的下部。所述刀台带动所述刀杆上下移动,所述刀杆向上移动用于内孔加工,所述刀杆向下移动用于螺纹加工。再进一步,所述刀杆轴向有冷却液孔,冷却液孔与所述镗孔刀、螺纹梳刀的安装位置连通。所述镗孔刀、螺纹梳刀与所述刀头焊接或铆接或通过螺栓固定连接。本技术的有益效果是,结构设计合理,使用一个刀杆即可完成油套管接箍的内螺纹加工,加工过程无需更换刀杆,既提高了生产效率又保证了螺纹加工质量。附图说明图1是本技术内螺纹加工组合刀具的结构示意图。图2是图1的后视图。图3是图1的A-A视图。图中:1.刀杆,2.镗孔刀,3.螺纹梳刀,4.刀头,5.刀 ...
