Description

The linear motor platform structure

(1) technical field:

A kind of linear motor platform structure of the utility model refers to a kind of X of work, the Y-axis linear motor platform to displacement especially.

(2) background technique:

Please cooperate and consult shown in Figure 7ly, be that known revolution motor drives platform, and it mainly is made up of to set of displacements 40 an X axis set of displacements 30 and a Y-axis;

This X axis set of displacements 30 has a pedestal 31, establish shifting seat 32 with the X axis cunning on this pedestal 31, a ball nut 33 is installed in the side of this bottom offset seat 32, this ball nut 33 combines with first ball screw 35 of one first motor 34, the end face of this bottom offset seat 32 is established a top offset seat 36 with Y-axis to cunning in addition, the side of this top offset seat 36 has a guide mechanism 361, and this guide mechanism 361 links to set of displacements 40 with this Y-axis;
