What are the characteristics of the electric translation table?

With the continuous improvement of the quality requirements of many research institutions and the continuous improvement of products by manufacturers, there are many types of electric translation table developed at present. The following small series will take you to understand the characteristics of electric translation table.

 1. The electric translation table can quantitatively convert the rotating motion of the motor into linear motion, and its energy conversion efficiency can reach 70% (ball screw). This index directly improves the load capacity of the electric translation table.

 2. The electric translation table has high motion accuracy. The positioning accuracy and repeated positioning accuracy can reach micron level. For example: if the driving motor is a stepping motor, the step angle of the motor is 1.8 °. The pitch of the driving lead screw is 4mm. It takes 200 steps for the motor to rotate for one circle. The linear displacement reflected on the translation table is the pitch of the lead screw. 4 mm. Then every action step of the motor. The linear displacement of the electric moving table is 4 / 200 = 0.02 mm In addition, the driver of stepping motor has pulse subdivision function Each action of the motor can be subdivided If 8 subdivisions are used Then every action of the motor Theoretically, the linear displacement of the electric moving table can reach the submicron level.

3. Changing different movement conversion forms can realize high-speed movement In many applications, it is necessary to improve the moving speed of the translation table In this case, the electric moving table usually appears in this form The drive is high-speed servo motor, and the drive is large pitch lead screw or gear rack drive Toothed belt, etc In this way, the speed of motion is improved without sacrificing accuracy and stability

4. When the electric translation table is used in combination, the tools installed on it can reach any point in three-dimensional space. Through linear interpolation control, complex motion trajectory can be realized.

A cross slide composed of two electric translation tables This slide is widely used in machine tools When the workpiece is fixed on it, the interpolation movement is realized by controlling the motor It can make the plane motion trajectory of the workpiece complex and changeable.

Through the above contents, I believe you have a deeper understanding of the electric translation table. If you have questions when purchasing, it is recommended to consult professional customer service, so as to select more suitable products.
