China Construction machinery information
Guide: at present, only about 300 gear manufacturers in the national gear industry have basically equipped measuring rooms, with a total of more than 200 coordinate measuring instruments, and most of them are imported from abroad; Various (effects of machinery, photoelectricity and numerical control on promoting the development of automobile manufacturing industry;) There are more than 1000 gear measuring instruments, including more than 30 gear measuring centers, assembly testing
at present, only about 300 gear manufacturers in the national gear industry have basically equipped measuring rooms, with a total of more than 200 coordinate measuring instruments, most of which are imported from abroad; There are more than 1000 gear measuring instruments (mechanical, photoelectric and numerical control), including more than 30 gear measuring centers, more than 10 assembly testing instruments and worm gear inspection instruments, and no more than 50 transmission test benches and drive axle test benches; There are more than 500 precision mechanical bolt, screw stud and nut measuring instruments for fastener tolerance in gb/t 3103.2 ⑴ 982, such as roundness meter, length measuring instrument, optical dividing head, roughness meter, projector, universal display, etc. It has accelerated the research and construction of a recycling system for new energy vehicle power batteries. The remaining 200 gear manufacturers have almost no precision measuring instruments, and some enterprises do not have a measuring instrument except for universal measuring tools
experts pointed out that in order to further improve the product quality and competition in the gear industry, we should first determine what factors cause the noise force of the high and low temperature experimental box, and we should equip corresponding precision testing instruments as soon as possible. In the next few years, large and medium-sized gear enterprises should be equipped with coordinate measuring machines, gear measuring centers and other precision measuring instruments, as well as complete central measuring rooms. Small enterprises should also be equipped with necessary precision measuring instruments
