Example Embodiment

[0033] The present invention will now be further described in conjunction with the embodiments and drawings:

[0034] Use the method of the present invention to process the "repetitive formation tester lower body" (see Figure 5 ) Machining of four double-angle holes on AX6, AX7, AX8, AX9:

[0035] The workpiece is positioned and clamped on the lower body by the worktable and tilting vise. Taking the AX7 double-angle hole as an example, the processing process is described in the following steps:

[0036] Step 1: Establish a coordinate system in the orthogonal state on the body, and draw a line with the lower point (279, 0) of the double-angle hole on the drawing as the origin of the coordinate system;

[0037] Step 2: Clamp the main body in the tilting vise to ensure that the straightness of the front jaw and the top surface of the main body in the X direction is less than 0.03mm;

[0038] Step 3: Turn the tilting vise to the angle of α:

[0039] among them: Is the designed angle betw...

Abstract

The invention relates to a method for processing a double-angle hole of the body of an oil well logging instrument. The method is technologically characterized by comprising the following steps of: drawing a cross curve on the upper surface of the body according to a design drawing, wherein a crossing point of the cross curve is a processing point of the double-angle hole; then clamping a workpiece on an inclinable vice; rotating the inclinable vice according to a calculated projected angle alpha; and rotating a power head for a angle beta and processing after finding the processing point correctly. The invention achieves the purpose that the shaft line of the workpiece is coincided with a main shaft of a machine tool by converting the sum theta of two design angles of the double-angle hole of the body into actual rotation angles alpha and beta of a tooling, thereby enabling the processing of the double-angle hole to meet design requirement; in addition, the invention has simple tooling, is convenient for operation, and provides a more ideal process method for the processing of various holes at spatial location.

Description

technical field [0001] The invention relates to a method for machining double-angle holes, in particular to a method for machining double-angle holes in a body of a petroleum well logging instrument, which belongs to the technical design of petroleum well logging instruments. Background technique [0002] The body in the petroleum logging instrument is a cuboid structure (see figure 1 ), including six planes of up, down, front, back, left and right. In solid geometry, if a straight line in a plane divides the plane into two parts, each part is called a half-plane, and the figure formed by two half-planes starting from a straight line is called a dihedral angle (this straight line is called The edge of the dihedral angle, each half-plane is called the face of the dihedral angle. The double-angle hole commonly used in the body is the hole on the face of the dihedral angle. The cutting point of the double-angle is on the upper surface of the body, and the section is perpendicu...
