Abstract

The invention discloses a scroll plate body error on-machine measurement method based on a four-axis numerical control milling machine, and aims to solve the problem of three-dimensional body error on-line rapid measurement in the scroll plate machining process. The measurement method comprises the following steps that based on a scroll plate numerical control machining tool, a milling cutter and a measuring head have a same installation connector, and after milling is completed, the milling cutter is replaced with the measuring head in a cutter changing mode. and the measuring head is a three-parallel inductance integrated measuring head, three sets of detection data in the vertical direction of a scroll plate can be obtained through one-time measurement after installation and calibration, and scroll body error evaluation of the scroll plate is completed. Based on the on-machine measurement method for the scroll plate error, the influence of repeated clamping errors when the scroll plate is measured on a traditional measuring instrument is avoided, and the measurement efficiency and the measurement precision are improved. Based on evaluation of errors of a three-dimensional vortex body, manufacturing errors of a vortex surface caused by workpiece and clamping errors or cutter local abrasion are evaluated in time in the machining process, and the limitation that only a single vortex line is subjected to error evaluation in traditional measurement is overcome.

Description

Technical field[0001]The present invention belongs to the field of precision measurement, and more particularly to a multi-axis body error in a four-axis-controlled milling machine.Background technique[0002]The electric vortex compressor has a small number of noise, high volume ratio, cleaning, conversion efficiency, and is widely used in the automotive air conditioning system due to the characteristics of small noise, high volume ratio, high degree of conversion efficiency compared to conventional compressors. The scroll is a key component of the electric scroll compressor. Its processing manufacturing accuracy determines the reliability and efficiency of the scroll compressor, high-precision and efficient scroll processing method and accuracy evaluation method are the key to manufacturing. .[0003]At present, the three-coordinate measuring machine is often achieved for the detection of the scroll, and the detection efficiency is low, and it is necessary to detect a special metering...
