A blade automatic measurement grouping machine and its measurement grouping method

Abstract

The invention discloses an automatic blade measurement grouping machine and a measurement grouping method thereof. The blade to be detected is automatically pushed into the blade thickness measurement device by the blade feeding device, and the measurement data is fed back to the program control by the electric measuring head of the blade thickness measurement device. The program controller compares the detection data according to the setting program, determines the tested blade group, and the program controller transmits the command to the blade intercepting grouping device, and the blade intercepting grouping device pushes the tested blade to the blade The corresponding collection grooves of the collection storage device are collected, thereby realizing the automatic grouping and measurement of the blades. The invention not only has the advantages of simple structure and convenient operation, but also has ingenious design, safety and reliability, and low equipment cost. Group collection can improve work efficiency, save manpower and material resources, have high use value, and improve the accuracy of blade group measurement.

Description

technical field [0001] The invention relates to an automatic blade measurement grouping machine and a measurement grouping method thereof, which belong to the technical field of part measurement grouping. Background technique [0002] At present, the output of my country's air-conditioning compressors has exceeded 120 million units, of which rotor-type air-conditioning compressors account for 80%. The blade is the core moving part of the rotor air-conditioning compressor. The quality of its parts is directly related to the key indicators such as the energy efficiency, life and noise of the compressor. It is generally made of high hardness, high wear resistance and corrosion resistance materials; the parts have a relatively high size And shape and position accuracy: parallelism and verticality <5 μm, size grouping 2-5 μm, grouping accuracy <1 μm, every size and shape position accuracy requirements of blades in production need to be checked in full. Air-conditioning com...

AI Technical Summary

Problems solved by technology

Air-conditioning compressors are mass-produced. In compressor production, users generally designate groups to manufacture. Therefore, the size tolerance of compressor blades is only 2-5 μm of the size group. Exceeding the size tolerance means a backlog of inventory, which causes blade manufacturing Difficulty, huge detection workload

[0003] In the prior art, the blades are manually measured and grouped. Each blade needs to detect the size of multiple points and judge according to the principle of grouping judgment. Each time the parts are manually transported, and the blades are measured one by one and then classified according to the specifications. Distinguish, because the blades are small and the number is large, it is easy to fatigue and misjudgment when grouping manually, and there are problems such as large measurement error, low efficiency, and high labor cost in manual grouping, so the existing method of measuring parts is still not perfect
