Abstract
V belt measures in the long milling machine's V belt transmission applies one of most widespread types of drive. V belt size correct or not, it has the very tremendous influence to the transmission performance: Besides requests V belt's section size to have certain accuracy, V belt's length must satisfy certain request, when particularly V belt when matches the group to use. Simultaneously in order to cause a group of V belt length which uses to be consistent, each V belt's length must control in a quite small error range, after often needs the special-purpose metroscope survey, it carries on matches the group. After the traditional production method is cuts V belt on the simple milling machine carries on the polish no longer to carry on measures is long. But uses the factory along with V belt to match the enhancement which and the industrial automation degree unceasing enhancement for V belt the group requests, at present many middle and small scale factory's simple dressers already appear the backwardness in the production method and the production efficiency, guarantees V belt size with difficulty the precision. After but if grinding, uses the special-purpose metroscope to carry on again matches the group, because not only increases measured that the long working procedure requires a lot of work increases the cost time-consuming, moreover, when the length cannot satisfy the request must return carries on the grinding. Under this kind of demand background, develops one kind new to be able online to measure that the long V belt length milling machine will decide will have the very good application prospect.
The present paper introduced this kind of new V belt measures the long milling machine's control system hardware design process. Below this kind of V belt milling machine must have the main feature: (1)it can online examine V belt length, measured that the long precision should achieve; (2) the reliability is high, can 24 hour continual grinding not crash; (3) uses the man-power besides the top and bottom belt, other abrasive belt process completely automatic control; (4) has independent measures the long function (its function and special-purpose V belt metroscope similar). According to the above function request, interrogation author, in has consulted many related literature material and analyzes compares domestic and foreign existing had measured that in the long dresser's good and bad points foundation, had determined control system's design proposal and has carried on the hardware design. This milling machine control system take the 80C51 monolithic integrated circuit as the control core, the Mitsubishi touchscreen is the man-machine contact surface, the software design uses the modular structure and the C language carries on the programming.
