Problems solved by technology

When the housing and the housing cover are assembled and processed, due to the length-to-diameter ratio L / D of the housing components (such as figure 1 ) is greater than 10:1, and the rigidity is poor. It belongs to the milling process on the slender shaft. The vibration of the shell components during processing causes defects such as cracks and chipping of the non-metallic shell cover, and the dimensional accuracy and surface roughness of the guide rail groove cannot meet the design requirements. Require

Embodiment approach

[0055] Below in conjunction with accompanying drawing, enumerate a specific embodiment, comprise the steps:

[0056] Step 1, the processing of the shell cover conversion device and the shell conversion device;

[0057] Process the shell cover conversion device and make the external thread size consistent with the shell cover, process the shell conversion device and make the internal thread size consistent with the shell;

[0058] Assemble through the external thread of the cover conversion device and the internal thread of the shell conversion device;

[0059] After assembly, mill the datum plane of the cover conversion device and the housing conversion device respectively, and mark four points a, b, c, and d on the datum plane according to the corresponding positional relationship during assembly (such as Figure 4 and Figure 6 shown);

[0060] Step 2, when disassembling and processing, process the circumferential guide rail groove of the shell and the circumferential gui...

Abstract

The invention discloses a threaded connecting piece shape matching machining conversion method. The method comprises the following steps of S1, separately machining a shell cover conversion device anda shell conversion device; after assembly, respectively milling the reference planes of the shell cover conversion device and the shell conversion device, and correspondingly labeling the shell coverconversion device and the shell conversion device; S2, machining a circumferential guide rail groove of a shell; and S3, machining a circumferential guide rail groove of a shell cover, wherein the machining position of the guide rail groove of the shell and the machining position of the guide rail groove of the shell cover are located on a same straight line. The invention further discloses a threaded connecting piece shape matching machining conversion device. According to the threaded connecting piece shape matching machining conversion method and device, the guide rail groove on the shellcover is machined after the shell conversion device reference position is determined according to the shell cover conversion device reference, and due to the unification of the conversion device reference and the rotation angle, the position matching performance and smoothness of the guide rail groove after assembly can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of matching processing of connectors, and more specifically relates to a method and device for shape matching processing and conversion of threaded connectors, which are applied to dismantling and processing of threaded connectors whose shapes have a matching relationship. Background technique [0002] The shell assembly consists of an aluminum alloy shell and a non-metallic shell cover, such as figure 1 . The shell assembly is assembled by connecting the internal thread of the shell and the external thread of the shell cover. The outer circumference of the shell and the shell cover needs to design guide rail grooves, and the angle between the center line of the guide rail groove and the ear drop line of the shell is α, such as figure 2 . The design requires that the guide rail groove must meet the matching and smoothness requirements after assembly. [0003] In the prior art, the processing method of t...
