Embodiment Construction

[0018] The invention provides a method for processing a Z-direction multi-axis part with a height difference, the method comprising the following steps:

[0019] 1) The bottom surface of the mounting seat is ground by flat grinding, so that the bottom surface of the mounting seat is the positioning reference plane;

[0020] 2) Install the component with the minimum height in the Z direction on the mounting surface; the mounting surface is opposite to the positioning reference plane; the axis of the component with the minimum height in the Z direction is perpendicular to the positioning reference plane;

[0021] 3) According to the size requirements of the parts to be processed, take the positioning reference plane as the reference plane, and grind the part on the upper end surface of the component with the minimum height in the Z direction, so that the height of the part with the minimum height in the Z direction is H1 ±0.003mm;

[0022] 4) Install the part with the sub-minim...

Abstract

The invention belongs to the field of mechanical manufacturing, and relates to a machining method for Z-directional multi-axis parts with height differences. The machining method comprises the following steps: 1) the bottom surface of a mounting base is grinded as a positioning reference surface; 2) a part with the smallest height is mounted on the mounting surface, and the axial direction of thepart with the smallest height is perpendicular to the line surface of the positioning reference surface; 3) the upper end surface of the part with the smallest height is grinded, so that the height isqualified; 4) a part with the second smallest height is mounted on the mounting surface, and the axial direction of the part with the second smallest height is perpendicular to the line surface of the positioning reference surface; and 5) with the upper end surface of the part with the smallest height as the reference surface, the upper end surface of the part with the second smallest height is grinded to achieve the qualified height. The machining method for the Z-directional multi-axis parts with height differences can accurately control the planeness, the verticality and the surface roughness, can realize quick machining, and effectively guarantees the pass percent.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a processing method for parts with height differences, in particular to a processing method for parts with height differences in Z-direction multi-axis. Background technique [0002] Such as figure 1 , figure 2 as well as image 3 As shown, the parts with height difference in the multi-axis in the Z direction, such as a height gauge composed of 15 feed gauges, have high dimensional accuracy of the feed gauge height difference (±0.003mm), and are difficult to process. The traditional processing method is to install all the feeding gauges on the mounting base first, and then grind the top surface of each feeding gauge separately by the tool grinder, and keep grinding 0.01-0.02mm at the same time, and finally manually grind to the drawing size. During the manual grinding process, the corners of the 15 feeding gauges are prone to collapse, which affects the shape and positi...
