Crusher Spindle System Thermal Deformation and then Crushing Remains Optimized

Crusher Spindle System Thermal Deformation and then crushing plant can be divided into the following categories:
Crusher Spindle SystemFirst, the thermal displacement and then crushing the detection device at the crusher shaft of the spindle axis line displacement and angular displacement of the heat value of the corresponding allowed to compare, if more than allowable value, servo movement began, through the device of the CNC system to the workpiece or a corresponding tool movement direction and then crushing to offset the crushing machine spindle thermal displacement caused by processing errors, such as Germany and Switzerland, the company’s GNIN FISCHER company can provide abundance axis elongation and then heated crushing device, FISCHER company uses sophisticated displacement sensors measure the crusher shaft elongation, GMN company is the first measurement of the temperature of the front bearing outer ring, then the projected axis of elongation of birth, then the number earned by the system re-crushing of the Z-axis.
Second, the thermal symmetry and then crushing, first of all temperature sensors on the system to measure the temperature of a typical area, when the temperature is not Shí symmetry than the preset tolerance, the relative position will be in heating or cooling by an external heat source , the system’s temperature to maintain symmetry and reduce the thermal deformation.
crusher spindleThe crusher, and then crushing the key technologies is to establish an appropriate model and error crusher, crushing mode again, now in the crusher for re-crushing, the University of Michigan Professor Chen presented including geometric error, including up to 32 online sources of error measurement, data processing and error and then crushing system; Shanghai Jiaotong University made a robust modeling method; many scholars using neural network approach to the crusher and then crushing. However, the use of heat and then crushing method has its limitations, such as during data acquisition, because of the accuracy of the sensor, and other factors, makes the collection of data may be distorted, so will the accuracy of the results of the re-crushing impact. Therefore, for problems arising crusher crushing, researchers still need to continue to look for a breakthrough technology in order to overcome.
