Application technology of STAF linear guide rail

According to the characteristics of machine tools in different application fields, the development trend of STAF linear guide rail for the international machine tool market. Several kinds of linear guide rail are developed. Promote the rapid development of machine tool industry, high precision, energy saving development of environmental protection.

The utility model relates to a novel rolling bearing for reciprocating linear motion, which is composed of a guide rail, a slide block, a reverser, a rolling body and a holding device. To the steel ball and the slider between rolling instead of sliding contact directly, and the rolling body can make use of inverter in the raceway and the slider within an infinite loop, which has the advantages of simple structure, and low friction coefficient, high positioning accuracy and precision to good.

The utility model is used for the linear reciprocating motion occasions which need to control the parallel degree of the worktable, and the linear guide rail is also called the precision rolling linear guide rail, a sliding rail, a linear guide rail, a linear slide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail, a rolling guide rail. It has higher rated load than linear bearing, can bear certain torque, and can realize high precision linear motion under the condition of high load.

Rely on the two sides of the guide rail or the ball rolling cycle of the four columns to drive the table in a given direction of the smooth movement of reciprocating linear motion. The linear rolling guide is used to support and guide the moving parts.

Linear motion guide rail can be divided into sliding friction rail, rolling friction rail, elastic friction guide rail, fluid friction rail and other types. Depending on the nature of the friction.

Adjustment of precision of ultra long linear rolling guide

1 long linear guide rail

Linear rolling guide has been widely used in various types of machine tools and non-standard equipment. In general, because of the machined surface as the installation datum and the length of application is limited, so it is easy to debug and measure. But for the long rail (greater than 8 meters), the commissioning and measurement will become a problem.

2 rail installation structure and precision requirements

The horizontal guide rail and the auxiliary guide rail of a near field test equipment are 13 meters in length and span of 1.5 meters. The leading rail plays a leading role, and the auxiliary rail plays a supporting role.

3 the main guide rail in the horizontal plane straightness adjustment

As the guide rail is made up of 13 1 m long precision guide rails on the base rail. In order to facilitate the assembly and debugging of the precision guide rail, we divide the process into two steps: coarse adjustment of rail and precise guide rail.
