The servo press drives the fine ball shaft through the synchronous belt to complete the accurate orientation control of the pressure spindle, and the high-sensitivity pressure sensor equipment is at the front end of the pressure spindle, which can detect the load of the pressure spindle in real time. Real-time collection of orientation and load data, complete the online quality management skills of fine pressure equipment.
Pressure and displacement control forms.
There are three forms of press-fitting:
Azimuth form: constant speed, set the absolute position to reach the pressure equipment to stop;
Pressure form: the speed is stable, and the relative pressure excitation is stopped;
Displacement form: constant speed, relative displacement to pressure equipment abort.
How to complete the pressure control of the servo press?
1. Displacement control form:
The pressure also changes with displacement. In the process of pressure equipment, we are able to monitor pressure changes at any time through built-in pressure sensors and high-speed data acquisition cards. When the pressure reaches the set maximum pressure, it immediately stops and controls the pressure.
2. Torque control form:
The torque control method of the servo cylinder is to set the output torque of the motor shaft by inputting an external analog quantity or assigning a direct address. After a calibration procedure, it is possible to calibrate the correspondence between torque and pressure, and then manipulate the pressure.
Pressure and displacement control forms.
How to judge the stability of the servo press?
1) Servo press displacement accuracy:
After the dial gauge, it can detect the displacement accuracy and control at the target value. The minimum displacement is set in units.
2) Accuracy of measuring servo pressure:
The loading force F1 is calibrated by the force transducer (weighing indicator) and measures +1%, and the gauge shows that the action is F2.

Introduction to laser encoders
Encoder: Laser encoder is a general term for encoders with laser as the light source. According to the published material, the principle can be broadly divided into two types, namely the use of the grating method and the use of the Fourier image method. Grating thousand-related method, where a laser of wavelength is projected on a periodic grating at a distance of p, ...

Application features of rotary incremental encoders
The rotary incremental encoder outputs pulses when it rotates, knows its orientation by the counting device, and remembers the orientation by relying on the internal memory of the counting device when the encoder does not move or the power goes out. In this way, when the power goes out, the encoder can not have any movement, and when the call is working, the encoder ...
