Three, product description
1. The main machine: the horizontal structure, composed of a transmission box, a chuck seat, a machine body, a controller, a computer and software, gear box in the left side of the host, AC servo motor and reducer, chuck a high-accuracy two-way torque sensor, can along the guide rail on the left and right moving; frame structure is adopted in the main structure, to ensure that the whole of rigid. Sample of the installation, disassembly, convenient, fast.
2. The guide rail: activities of the chuck end with a precision linear guide and adjust the operating space, with high rigidity and high accuracy, precision grade precision; guide rated carrying high ability, the allowable vertical load, to withstand the high torque, high anti overload capacity; guide dustproof and self lubrication system is more reasonable;
3 measurement and control technology: the measurement and control system of all digital measurement controller using the most advanced technology. DSP (digital signal processing) technology based on FPGA (high density field programmable gate array). It is characterized by high speed processing ability, ultra low noise, high anti jamming. Automatic zero adjustment, automatic calibration and other functions. With overload, over stroke, over voltage, over current, over heat, etc..
4 drive system: the use of AC servo motor and AC servo driver, speed adjustment range, loading uniform, stable, high precision servo control, long service life.
5 transmission system: the use of imported Swiss equipment production of planetary gear reducer transmission, ensure that the transmission of uniform, stable and transmission accuracy, the horizontal space range of arbitrary manual adjustment.
6 computer system and software package: strict accordance with the relevant standards of the test data to calculate the exact statistics, and equipped with a sound data query function, print function, export function to ensure the accuracy of the test data, reliability, real and reflect the nature and characteristics of the material itself. Modular test management software of each function is an independent module, such as the calculation of the base and the control of test hangar, etc. are independent modules, to upgrade or change only alone on its own can be modified without the need to change the whole system.
