Embodiment Construction

[0027] Such as Figures 4 to 6 As shown, taking a diamond-shaped plug gauge with a handle part diameter of Φ8mm, a diamond-shaped side length of 4.8mm in the working part, and a diamond-shaped angle of 82° as an example, the processing method includes the following specific steps:

[0028] (1) Preparation of materials: select forgings with intact materials, no cracks, and no blisters;

[0029] (2) Turning process: the working part and the handle part are pushed into shape, first calculate the lengths of the two diagonals of the rhombus of the working part as 7.32mm and 6.36mm respectively, and carry out the outer circle to Φ8 according to the length of the longest diagonal .5mm, knurling on the handle part, such as Figure 7 shown;

[0030] (3) Milling process: Milling the marked surface, that is, the flat part of the B-B section, is used to write the product specification, drawing number, year, month, etc., and then according to the size requirements of the diamond plug gau...

Abstract

The invention provides a rhombus plug gauge processing method includes the following steps of preparing materials, selecting forge piece blanking which is intact in materials, and free from flaws and sand holes, carrying out lathe operator process, miller process, heat treatment process, sand blowing process, surface treatment process, and cutter grinding process, firstly grinding a D surface and a surface parallel to the D surface until required sizes are reached, then enabling a rhombus plug gauge to be clamped on a sine platform, enabling the grinded D surface and the surface parallel to the D surface to face the left side face and the right side face of the sine platform, wherein two non-grinded surfaces face the upper surface and the lower surface of the sine platform, calculating thickness of a feeler gauge according to angle of the rhombus, enabling the feeler gauge to be cushioned under the sine platform, enabling a grinding wheel to begin to carry out cutting feed along the track of the grinding wheel, firstly grinding an E surface, then turning the rhombus plug gauge to begin to grind a surface parallel to the E surface after the E surface is well grinded, carrying out fitter process, and carving marks. The rhombus plug gauge processing method reduces processing difficulty of the rhombus plug gauge, and ensures accuracy requirements of the rhombus plug gauge.

Description

technical field [0001] The invention relates to a processing method of a rhombic plug gauge, which belongs to the field of mechanical processing. Background technique [0002] Various forms of measuring tools are often required in actual mechanical production and processing, and each measuring tool has its range of measurement applications. The special diamond plug gauge is used to check whether the processing of the diamond groove meets the design requirements. Since the diamond plug gauge is a precision part for measurement, its processing is of great significance. However, in the prior art, due to the special shape of the rhombus itself, the processing method adopted by the rhombic plug gauge makes the processing difficult, and the workpiece is often scrapped because the accuracy required by the rhombus plug gauge cannot be met. [0003] The diamond plug gauge includes the working part and the handle part. CrWMn is usually used. This material is the most commonly used hi...
