Automatic detection apparatus and control method for roll grinder

Abstract

The invention mainly relates to the technical field of the control of a roll shaped measuring device used for a roll grinder, particularly to a roll grinder automatic detecting device and the control method thereof. The automatic detecting device comprises a man-machine interface (1); the man-machine interface (1) is connected with a control system (2) through a PROFBUS communication bus; the automatic detecting device further has the characteristics that the control system (2) is connected with a servo module (3) through a data bus; the control system (2) is connected with a speed count unit (4) through an I / O bus; the servo module (3) is connected with a control module (7) used for controlling an X, a Z, an XI, a U and a D shafts of a machine tool; the speed count unit (4) is connected respectively with a first sensor (5) and a second sensor (6) through data lines; and the automatic detecting device uses a Siemens 840 D numerical control system and the developed special process control software to complete the grinding process and the control logic of the whole grinder. The automatic detecting device has the advantages of high control accuracy, improves the work efficiency of the machining tool, and reduces the labor intensity of an operator.

Description

Technical field: [0001] The invention mainly relates to the technical field of control of a roll shape measuring device used for a roll grinder, in particular to an automatic detection device and a control method for a roll grinder. Background technique: [0002] Roll grinder is an indispensable and important production equipment in modern industrial production. It is mainly used in metallurgy, papermaking and other industries. Its grinding mechanism has the characteristics of general large-scale cylindrical grinders, but it is different from general cylindrical grinders. In addition to grinding cylinders, (grinding flat rolls, roll support diameters), the grinding machine can also grind various roll surfaces with convex, concave and arbitrary curved surfaces on the rolling mill. The movement of the grinding wheel is much more complicated. In addition to the relative rotary motion (main motion) between the grinding wheel and the workpiece (roller), it is also required that t...

Problems solved by technology

[0003] With the development of science and technology, the requirements for rolled parts in metallurgy, papermaking and other industries are getting higher and higher. At present, the rolled parts are required to be thinner and thinner at home and abroad, and the thickness tolerance and surface roughness are getting higher and higher. In this way, ordinary roll grinders can no longer To meet the processing requirements, it is imperative to develop multifunctional CNC roll grinders, and the requirements for roll shape detection methods are getting higher and higher, and it is difficult to meet the requirements of metallurgy, papermaking and other industries for rolls by manual detection by operators.
