Processing method for engineering diamond core drill matrix

金刚石工程薄壁钻基体的加工方法

Abstract

本发明涉及薄壁钻头制造技术领域,尤其涉及一种金刚石工程薄壁钻基体的加工方法,为了解决传统的金刚石工程薄壁钻基体加工工艺的效率低、精度低、损耗大的问题,其特征是金刚石工程薄壁钻基体由钢管体、接头片和接头组成,接头片的外径与钢管体的外径相等,接头片与钢管体连接部位设有凸台,凸台的外径与钢管体的内径间隙配合,接头片的内孔一周均匀分布若干个齿凹,接头的一端设有与齿凹配合的齿凸,钢管体的加工夹持采用中心架的弹性套装置,所述的弹性套装置设有管状弹性套,弹性套内孔一端设有钢管体定位座,弹性套筒壁上沿轴向设有若干条通槽,弹性套外径上装有定位套和锁紧螺母。原材料损耗低,生产效率高。
The invention relates to the technical field of core drill bits, in particular to a processing method for an engineering diamond core drill matrix, which aims to solve the problems of low efficiency, low precision and more loss of traditional engineering diamond core drill matrix processing technique. The processing method is characterized in that the engineering diamond core drill matrix comprises a steel pipe, a joint piece and a joint, the outer diameter of the joint piece is equal to that of the steel pipe, a boss is arranged at the connection position of the joint piece with the steel pipe, the outer diameter of the boss is in clearance fit with the inner diameter of the steel pipe, a plurality of concave teeth are evenly distributed on the periphery of an inner hole of the joint piece, convex teeth matched with the concave teeth are arranged at one end of the joint, the steel pipe is processed and clamped by an elastic sleeve device of a center frame, the elastic sleeve device is provided with a tubular elastic sleeve, a steel pipe positioning seat is arranged at one end of an inner hole of the elastic sleeve, a plurality of through grooves are axially arranged on the wall of the elastic sleeve, and a positioning sleeve and a locking nut are mounted on the outer circumference of the elastic sleeve. Fewer raw materials are consumed, and production efficiency is high.
