Automatic machined part measuring system and automatic scoring method

Abstract

The invention relates to an automatic machined part measuring system and an automatic scoring method. The measuring system comprises a non-contact measuring mechanism and a testing service station, the testing service station is connected with the non-contact measuring mechanism, a numerical control machine tool, a school teaching management system and a mobile phone of a trained student through anetwork and comprises laser, a visual signal processing unit, a numerical control machine tool data acquisition unit, an automatic machined part scoring unit, a school teaching management system interaction unit and a mobile terminal interaction unit, the scoring unit acquires total training score A, A=k1*A1+k2*A2+k3*A3+k4*A4, k1, k2, k3 and k4 are score weighting coefficients which are set according to practical situations by mentors, default values are given by the system, A1 refers to machining dimension precision score, A2 refers to machining technology quality score, A3 refers to machining efficiency score, and A4 refers to attendance discipline score.

Description

technical field [0001] The invention relates to the technical field of automatic grading of machined parts, in particular to an automatic measurement system and an automatic grading method for machined parts, which can obtain the training results of students after processing the relevant measured data. Background technique [0002] China has become the world's largest manufacturing country. Correspondingly, the country has also established the world's largest talent training system. As long as there are engineering schools, there will be electromechanical training. The most typical electromechanical training project is CNC machine tool operation and processing training. Due to the limited number of teachers, this kind of practical training generally has the phenomenon of many students and few instructors. As a result, instructors mainly rely on feeling and experience when evaluating the performance of students during training. Or simple measurement to give results. The teach...

The most typical electromechanical training project is CNC machine tool operation and processing training. Due to the limited number of teachers, this kind of practical training generally has the phenomenon of many students and few instructors. As a result, instructors mainly rely on feeling and experience when evaluating the performance of students during training. Or simple measurement to give results. The teacher needs to measure the dimensional accuracy, shape tolerance and other indicators of the processed parts. On the one hand, special measuring instruments and tooling are needed. Significantly reduced, the result is dissatisfied students, dissatisfied schools, dissatisfied teachers, affecting the quality of training
