introduction：We all know that with the development of science，Photoelectric sensors are also increasingly inseparable from our lives。Photoelectric sensor is a sensor using photoelectric element as a detection element。It first converts the measured change into a change in the light signal，The light signal is then further converted into an electrical signal with the help of a photoelectric element。Photoelectric sensorGeneral light source、The optical path and the photoelectric element are composed of three parts。 Structural analysis： Photoelectric sensors usually consist of three parts，They are respectively：transmitter、Receiver and detection circuit。 The transmitter has a calibration lens，Focus the light towards the receiver，A receiver outlet cable connects the unit to a vacuum tube amplifier。Inside the metal cylinder is a small incandescent lamp as a light source，These small but sturdy incandescent light sensors were the prototype of todays photoelectric sensors。

introduction：The feed system of CNC machine tools requires higher transmission stiffness，In addition to the stiffness of the ball screw nut itself can be strengthened， The correct installation of the ball screw and the stiffness of the supporting structure are also factors that cannot be ignored，Therefore, the nut seat and support seat of the screw should have sufficient stiffness and accuracy。It is generally done by appropriately increasing the contact area of the combined parts with the machine tool，To improve the local stiffness and contact strength of the nut seat,Newly designed machine tools often have nut seats or supports when technological conditions permit The bearing seat is integrated with the machine body to increase the stiffness。
