Embodiment Construction

[0019] This embodiment is carried out on a self-developed MB2-50 vertical honing machine. The parts are fuel injectors for automobile engines. The diameter of the workpiece is Φ12mm. The spindle speed is set at 1200 (rpm), the reciprocating speed of the oil cylinder is 140 (mm / s), and the length of the reciprocating stroke: 50 (mm). Among them, the honing machine provides up to three stages of honing feed, and there are additional non-feeding short strokes and finishing stages. The specific parameters are set as follows:

[0020] 1) The first feed: total feed: 4 (μm), feed 1 (μm) per reciprocating stroke, reciprocating 4 times.

[0021] 2) The second feed: the total feed: 1.6 (μm), the feed of each reciprocating stroke is 0.4 (μm), reciprocating 4 times.

[0022] 3) The third feeding: the total feeding amount: 0.4 (μm), the feeding amount per reciprocating stroke is 0.1 (μm), reciprocating 4 times.

[0023] 4) Finishing: reciprocating 4 times

[0024] The data acquisition ...

Abstract

The method for monitoring honing strip state in the internal hole vertical honing machining process includes the following steps: (1) power transformer can be used for collecting current and voltage signals of honing main shaft motor from frequency converter of honing main shaft motor; (2) the power display meter can be used for receiving voltage signal which is directly proportional to the instantaneous power of main shaft motor from power transformer, selecting power display meter with signal output port; (3) after the signal of starting data acquisition is received by computer, the data acquisition card can be started acquiring instantaneous power of honing main shaft motor from power display meter output port; (4) adopting Lab VIEW technique to implement on-line honing main shaft motor power signal real-time graphic display in the honing machining process; and (5) utilizing PLC technique to make monitoring subprogram so as to implement the invented method.

Description

technical field [0001] The invention relates to a method in the technical field of mechanical processing, in particular to a method for monitoring the state of a honing stick during the inner hole vertical honing process. Background technique [0002] High-precision honing is an effective precision machining method to improve the geometric shape accuracy of the workpiece and reduce the surface roughness. The machining geometric accuracy can reach: cylindricity 0.5μm, cylindricity 1μm, surface roughness Ra0.04; Since the honing surface has a cross texture, the lubricating oil is easy to store and the oil film is easy to maintain, so that they are not easy to wear and prolong the service life. The inner hole vertical honing process is a closed processing method. The state of the honing rod has an important influence on the honing process. The normal wear and abnormal wear or damage of the honing rod are inevitable in the honing process. The normal wear of the honing rod It wi...
