Chiziqli modulli toymasin stol avtomatlashtirish uskunalarida eng ko'p ishlatiladigan standartlashtirilgan moduldir. Modulli toymasin stollarning xilma-xilligi tufayli, tanlov jarayonida, agar tanlov to'g'ri bo'lmasa, bu uskunaning ishlashi va loyihaning rivojlanishiga turli muammolarni keltirib chiqaradi. Shuning uchun chiziqli modullarni tanlash juda muhim.
Chiziqli modul slaydni tanlash quyidagi bosqichlarga murojaat qilishi mumkin:
1. Determine the operating environment of the linear module sliding table: According to the operating environment, determine it as a general environment, a clean environment, or a harsh environment?
2. Determine the installation direction of the linear module sliding table. Make sure that the module sliding table is installed horizontally, wall-mounted or vertical.
3. Determine the load carried by the linear module sliding table.
4. Calculate the speed and acceleration of the sliding table of the linear module.
5. The allowable torque check of the linear module sliding table: calculate the torque values in each direction under the static (constant speed) state and the acceleration and deceleration state: Ma, Mb, Mc.
6. The accuracy level requirements of the linear module sliding table: specify the required repeat positioning accuracy, walking parallelism requirements, etc.
7. Determine the motor installation style: the commonly used linear module sliding table installation methods include direct connection, installation on the left side of the motor, installation on the right side of the motor, installation on the bottom side of the motor, etc.
8. Linear module sliding table stroke limit switch mode.
9. Determine the motor specifications and power of the linear module sliding table.
The performance index of the linear module sliding table can be measured from the following aspects.
The accuracy characteristics of the linear module sliding table: including repeated positioning accuracy, positioning accuracy, walking parallelism, walking straightness, backlash, etc.
The motion characteristics of the linear module sliding table: loadable weight, torque resistance, running speed, acceleration, running noise, etc.
