The invention discloses a method and a device for testing the machining temperature of a machine tool and relates to the field of machining of machine tools. The method for testing the machining temperature of the machine tool comprises the following steps: acquiring basic image information and temperature distribution state information of a target region of the machine tool when the temperature of the machine tool reaches dynamic balance; determining a temperature measurement key point of the target region according to the temperature distribution state information, and determining the position of the temperature measurement key point in the target region of the machine tool according to the basic image information; and controlling the testing device to test the temperature of the temperature measurement key point. According to the method and the device disclosed by the invention, a temperature test key point is determined by acquiring the basic image information and the temperature distribution state information of the target region of the machine tool in advance, the testing device is controlled to perform a temperature test on the temperature measurement key point, thermal imaging temperature measurement is combined with the method to firstly acquire the temperature measurement key point, then the temperature of the key point of the target region is measured in a contact type temperature measurement manner, and thus an accurate temperature measurement result can be acquired quickly.
Description
technical field [0001] The invention relates to the field of machine tool processing, in particular to a method and device for testing machine tool processing temperature. Background technique [0002] In the process of machine tool processing, machining accuracy is an important indicator for evaluating the quality of machine tools. According to data, the machining error caused by thermal deformation in the machine tool industry accounts for more than 40% of the total error, and the cause of thermal deformation is the temperature of the machine tool caused by various heat sources. field changes. [0003] As the lines and parts on the PCB become more and more dense, the precision requirements for the PCB board continue to increase, so that the requirements for the machining accuracy of the PCB machine tool are also getting higher and higher, and even the machining error of the machine tool is required to be controlled within a few microns. For this reason, It is necessary to...
