Intelligent joint coordinate measuring machine developed in 6354

Measurement equipment, from manual to read through the keyboard into the system tester. In automatic mode, in addition to the atmospheric pressure signal, all the pressure, temperature, time parameters collected automatically by the system. At the same time the surface pressure on the tester, the device pressure, surface temperature, device temperature, the four parameters of the procedures manual input is disabled. When the input data is complete, turn valves, Bell began to run, press the start button tester, the test device to work, ready to receive optical sensor sends a pulse signal, the first pulse arrives, the beginning of the cycle collected four variables transmitter signal,[link widoczny dla zalogowanych], and its average basis, while some start measuring time CPLD, these measurements are stored and sent to the microcontroller in real time displayed on the LCD screen for reference by the operator observation. After receiving the first pulse, the tester will stop receiving photoelectric sensor signal. Specify the volume until the microcontroller to send out instructions to be completed only after receiving photoelectric sensor signals the beginning again, and completed on behalf of the specified volume pulse arrives to stop counting. Microcontroller based on collected data,[link widoczny dla zalogowanych], using the formula (2) to calculate the actual flow value and the L / min unit display. At this point, a calibration is completed. 3 Specifications and application effect of gas flow device Bell transformed through automation, the technical indicators: time measurement uncertainty: ± 0.05 (a 2); flow measurement uncertainty: ± 0.5 (a 2). Transformation of the former calibration, you need to use the stopwatch to measure time, one person, one control valve, one data processing, time-consuming. After transformation, the standard easy to use, as long as one person to complete all the work, and the calibration of the time just before the 1 / 5. After transformation,[link widoczny dla zalogowanych], the standard equipment used on a number 0D09M0064, model D07 of the digital mass flow meter calibration, the data shown in Table 1. From the calibration results, to meet the technical requirements. Table l digital mass flow meter calibration data L / rain the actual value of the nominal value of tolerance 198.18196198.29 ± 4198.4O99.459999.53 ± 499.4941.634041.61 ± 441.624 Conclusion The transformation was complete automation After the Bell Test gas flow automatically apply to the four existing CAC Bell volume gas flow device, making the calibration automatically converted entirely by hand, and in line with JJG257-94 \\Reduce the calibration staff, improve efficiency, ensure the CAC on the production schedule and product quality requirements. The automation of the cost of just 1.5 million, for the CAC in substantial cost savings. References E13JJG257-94, rotameter national metrological verification regulations Es3.

Intelligent joint coordinate measuring machine developed in 6354 by China Shipbuilding Industry Group Corporation, 6354, Hefei University of Technology Institute and co-developed an intelligent ZGC a joint coordinate measuring machine near El Jiangxi Science and Technology Department through the auspices of a new product identification and scientific and technological achievements appraisal. Identification of the Committee that: the product to fill the gap. Reached the international advanced level, product design is reasonable, advanced technology, easy to use. Potentially significant economic benefits. Have broad application prospects. ZGC-l Intelligent joint coordinate measuring machine is designed based on biomimetic principles of a non-orthogonal spatial structure of the new series coordinate measuring system, the body consists of six rotary joints, three rigid arm and the probe composition, and computer and measurement software together to complete spatial position measurement. The main technical indicators: measuring range: 2.4m; space length measurement accuracy: ± 0.07mm; instruments total weight of not more than lOkg. The machine is small, light weight, portable, high accuracy, the probe can be replaced to suit different occasions, with the external balance of body, joint free to rotate, no measurement dead easy to use, for industrial site, the product mapping ,[link widoczny dla zalogowanych], reverse engineering and so on,[link widoczny dla zalogowanych], is to achieve high performance, low-cost measurement of the ideal tool.
