Description

一种双顶尖外圆加工工装A double-tip outer circle processing tool

技术领域 technical field

本发明涉及机械加工夹具,尤其涉及一种双顶尖外圆加工工装。 The invention relates to a machining fixture, in particular to a double-tip outer circle processing tool.

背景技术 Background technique

外圆加工工装主要有传统的双顶尖加工工装和液压驱动顶尖加工工装两种,其中传统的双顶尖加工工装是采用前顶尖和后顶尖配合夹紧工件,在工件靠近前顶尖的一端套上鸡心夹头用于传递扭矩带动工件旋转。安装鸡心夹头后会对加工造成干涉,要加工工件全长不得不掉头分两次装夹,既浪费时间,又影响了工件位置精度,在加工位置精度要求较高的零件时,会导致不合格甚至直接报废。液压驱动顶尖虽然实现了一次加工全长、工件的位置精度也较高,但是传递扭矩需要依靠拔针嵌入工件端面,工件端面会受到损坏;顶尖为液压驱动,成本较高,尤其是压力较大,不适合细轴的加工;不适合加工单件及小批量零件,不能在经济型车床和普通车床上使用,使用范围存在局限。 There are two main types of cylindrical processing tooling: traditional double-top processing tooling and hydraulic-driven top processing tooling. The traditional double-top processing tooling uses the front top and rear top to clamp the workpiece, and put a chicken heart on the end of the workpiece near the front top. The collet is used to transmit torque to drive the workpiece to rotate. The installation of the chicken heart chuck will interfere with the processing. To process the full length of the workpiece, it has to be turned around and clamped twice, which not only wastes time, but also affects the position accuracy of the workpiece. Qualified or even scrapped directly. Although the hydraulically driven tip can process the full length at one time and the position accuracy of the workpiece is also high, the torque transmission needs to be inserted into the end surface of the workpiece by pulling out the needle, and the end surface of the workpiece will be damaged; the tip is driven by hydraulic pressure, the cost is high, especially the pressure is high , It is not suitable for the processing of thin shafts; it is not suitable for processing single and small batch parts, it cannot be used on economical lathes and ordinary lathes, and the scope of use is limited.
