Description

Grating ruler mounting structure

Technical Field

The utility model belongs to the technical field of machine tool equipment, and particularly relates to a mounting structure of a grating ruler.

Background

Grating scales, also known as grating scale displacement sensors (grating scale sensors), are measurement feedback devices that work using the optical principles of gratings. The grating ruler is often applied to a closed-loop servo system of a numerical control machine tool and can be used for detecting linear displacement or angular displacement. The signal output by the measuring device is digital pulse, and has the characteristics of large detection range, high detection precision and high response speed. More specifically, the numerical control system performs machining according to the position information fed back by the grating ruler, so that the accuracy of the grating ruler directly determines the machining accuracy of the numerical control machine tool.

The traditional structure consists of a scale grating and a grating reading head. The scale grating is generally fixed on a machine tool transmission part, and the grating reading head is arranged on a machine tool fixing part and used for detecting the coordinates of a cutter and a workpiece so as to observe and track a feed error and play a role in compensating the motion error of the cutter. However, the structure can cause the grating ruler to generate measurement deviation due to the operation thermal expansion effect on the transmission part of the lathe, and the grating mounting surface of the ruler is small in rigidity and low in rigidity, so that the machining precision of the lathe is affected.

Therefore, how to provide a high-rigidity, high-precision and stable-running mounting structure for a grating ruler is a problem to be solved by those skilled in the art.
