Embodiment Construction

[0031] The present invention will be described in detail below through the accompanying drawings and specific implementation examples. However, the following examples are only intended to explain the present invention, and the protection scope of the present invention includes the entire contents of the claims.

[0032] like image 3 As shown, a specific embodiment of the manufacturing method of the single-track absolute grating scale roller imprinting method of the present invention is realized by the following steps. The method includes the following steps:

[0033] The first step: roll stamping mold processing. On the cylindrical mold base 1, a helical strip 2 with a certain width and a rising angle is processed through turning, grinding and polishing processes, such as figure 1 shown.

[0034] The mold base 1 used in this example is made of stainless steel 4Cr13, the outer diameter of the spiral belt 2 is D=100mm, the width is 15mm, the rise angle is 10 degrees, the nu...

Abstract

The invention discloses a roll-in printing manufacturing method of a single-track absolute type grating ruler, which utilizes a spiral roll-in printing mould to carry out pressing replication on a metal material layer on the surface of a grating ruler blank by a roll-in printing process. The shape of the spiral roll-in printing mould is a spiral line belt with a lifting angle of theta; a single-track absolute type grating grid line is manufactured on the spiral line belt through rotary photoetching and wet-method etching; a grating ruler blank is horizontally placed between the roll-in printing mould and a supporting roller; and under the effect of a pressing force of the roll-in printing mould, the metal material layer on the grating ruler blank is subjected to plastic deformation and a grating grid line groove on the spiral line belt of the roll-in printing mould is filled, so that an single-track absolute type grating ruler grid line is formed on the grating ruler blank. According to the method disclosed by the invention, the spiral line belt is wound on a base body of a cylindrical roller mould by a plurality of circles and the single-track absolute type grating ruler with a customized length can be manufactured by a roll-in printing method; and compared with the traditional manufacturing manner of the absolute type grating ruler, the roll-in printing manufacturing method has the technical advantages of batch production, rapidness and low cost.

Description

technical field [0001] The invention relates to the technical field of a single-code-track absolute grating ruler, in particular to a roll imprint manufacturing method of a single-code-track absolute grating ruler. technical background [0002] As the measurement and closed-loop feedback control element of the running position of CNC machine tools, the grating ruler is the key basic functional component of precision and ultra-precision CNC machine tools, and it is also the most critical measurement component. effect. [0003] The current grating ruler can be divided into two types: incremental type and absolute type according to the measurement method. Compared with the incremental grating size, the absolute grating scale provides the current position value immediately when the machine is turned on. Because it does not need to execute the reference point return procedure, the technology is reliable and safe, and it is widely used in the CNC machine tool and testing instrume...
