Processing method of body angle spherical capstan in petroleum instrument

Abstract

The invention discloses a method for machining an angle ball twist base of a body in a petroleum instrument. The method includes the steps that firstly, position coordinates of the point of intersection of the installing surface of the angle ball twist base on the side face of a square inner cavity of the body and the axis of a ball twist base hole are determined; secondly, a forming electrode with a conical tip is designed; thirdly, the forming electrode is utilized to conduct tool setting on the installing surface of the angle ball twist base on the side face of the square inner cavity of the body, wherein a tool setting point is the contact point of the conical tip of the forming electrode and the installing surface of the angle ball twist base; fourthly, position coordinates of the conical tip of the forming electrode on the installing surface of the angle ball twist base on the side face of the square inner cavity of the body are determined; fifthly, the coordinate difference value between the position coordinates of the point of intersection in the first step and the position coordinates of the conical tip in the fourth step is calculated; sixthly, according to the coordinate difference value, digital control codes are coded, the motion track of the forming electrode is controlled, and the conical tip in the fourth step is made to coincide with the point of intersection in the first step. The method for machining the angle ball twist base of the body in the petroleum instrument has the advantages that machining is easy to conduct, and machining cost is low.

Description

technical field [0001] The invention belongs to the processing field of petroleum logging instruments, and relates to a processing method for an angled hole on the inner cavity side wall of a petroleum logging instrument, in particular to a processing method for an angled spherical seat of a petroleum instrument. Background technique [0002] There is a rectangular inner cavity in the middle of the body of the petroleum logging instrument. The side wall of the inner cavity needs to be processed with a certain angle, a certain size accuracy, and a certain position accuracy. The ball joint seat is the channel for the formation sample to flow in. It is also the fulcrum of the mud ball strand connecting rod system. [0003] The processing method of the body ball winch seat in the existing petroleum logging instrument is: [0004] 1. The main body is designed into a separate structure, and the closed cavity is changed into an open cavity to facilitate the processing of the ball ...

Problems solved by technology

The disadvantage of the technical solution disclosed in this document is that the calculation is cumbersome, especially for the processing difficulties encountered in angle holes with an aperture ratio greater than 20, no solution is proposed

[0008] In June 2007, in the article "Auxiliary Tooling Design for Special Angle Hole Processing" published by Luo Zhengbin in "Water Conservancy and Electric Machinery", for parts with special angle holes, through the design of auxiliary tooling, the problem of accurately processing parts was successfully solved. The problem of the clamping process of the oblique holes at angles of 21° and 30° on the horizontal plane, the technical solution disclosed in this document has the disadvantage of limited machining accuracy and cannot meet the requirements of high-precision hole positions
