Description
Technical Field
The invention relates to a turning force measuring technology in turning processing, in particular to a turning force measuring cutter system with a direct inserting type sensitive structure.
Background
During the turning process, the turning forces directly affect the deformation of the process system, tool wear, power consumption and the generation of cutting heat. Therefore, the measurement of the turning force has very important significance for researching the turning mechanism and guiding the actual turning process. Under the conditions of the prior art, the measurement of the turning force is mainly realized by adopting a strain gauge or a piezoelectric type gauge which is arranged on a cutter. However, the two types of load cells have the following problems due to the structure and installation manner of the load cells: first, the strain gauge has problems: due to the limitation of the resistance strain gauge pasting process, on one hand, the measurement accuracy is low, and on the other hand, the resistance strain gauge pasting process is not suitable for being used in a high-temperature environment, so that the application range of the resistance strain gauge pasting process is limited. Secondly, the piezoelectric type dynamometer has the following problems: due to insufficient unidirectionality of the piezoelectric crystal, the piezoelectric crystal has mutual interference when measuring three-dimensional force and has hysteresis when measuring static force, so that the measurement precision is low. Thirdly, the common problems of the strain dynamometer and the piezoelectric dynamometer are as follows: the volume is large, so that the application range is limited. Fourthly, the problem that strain dynamometer and piezoelectric dynamometer exist jointly still includes: the dismouting process is too loaded down with trivial details, leads to it can't realize the range and changes, leads to it from this to realize the multirange measurement on same cutter. Therefore, a turning force measuring tool system with a direct inserting type sensitive structure is needed to be invented, so that the problems that the existing turning force measuring technology is low in measuring accuracy, limited in application range and incapable of realizing multi-range measurement on the same tool are solved.

When the system works, the output end of the Wheatstone bridge circuit is connected with the input end of the signal processing module; the output end of the signal processing module is connected with the input end of the PC. The specific working process is as follows: when turning is carried out, the tool tip of the turning tool blade is subjected to turning force, the turning force acts on the elastic square beam and the four rectangular elastic substrates through the turning tool bit and the inserting and embedding seat which is arranged at the position close to the front in sequence, so that the elastic square beam and the four rectangular elastic substrates generate large stress, the elastic square beam and the four rectangular elastic substrates are deformed, and the four film sensors are deformed. At the moment, because the output signals of the four film sensors are inconsistent, the Wheatstone bridge circuit is in an unbalanced state, the Wheatstone bridge circuit outputs a voltage signal, the voltage signal is processed by the signal processing module and then transmitted to the PC, and the PC can acquire turning force information in turning in real time according to the received voltage signal. In the process, the four runway-shaped grooves can obviously reduce the section inertia moment of the elastic square beam on one hand, and can obviously enlarge the distance between the four film sensors and the elastic square beam on the other hand, so that the output sensitivity of the Wheatstone bridge circuit is improved, and the measurement accuracy is improved. According to the actual measurement requirements, sensitive structures with different measuring ranges (namely four rectangular elastic substrates and four thin film sensors) can be replaced, so that the measuring range replacement is realized. The specific replacement process is as follows: the original sensitive structure is firstly pulled out from the two inserting and embedding seats, and then the sensitive structures with different measuring ranges are inserted and embedded on the two inserting and embedding seats, so that the measuring range replacement is realized, and the multi-range measurement is realized on the same cutter.
Based on the process, compared with the existing turning force measuring technology, the turning force measuring tool system with the direct inserting type sensitive structure realizes integration of the turning processing function and the turning force measuring function by adopting a brand new structure, thereby having the following advantages: firstly, compared with a strain type dynamometer, the strain gauge is not affected by the limitation of a resistance strain gauge pasting process any more, so that the measurement precision is higher, and the strain gauge is suitable for being used in a high-temperature environment, so that the application range is not limited any more. Secondly, compared with a piezoelectric dynamometer, the piezoelectric dynamometer is not affected by insufficient unidirectionality of the piezoelectric crystal any more, so that mutual interference does not exist when the force is measured in three directions, and hysteresis does not exist when the static force is measured, so that the measurement precision is higher. Thirdly, compared with strain type dynamometers and piezoelectric type dynamometers, the piezoelectric type dynamometers have smaller volumes, so the application range of the piezoelectric type dynamometers is not limited any more. Fourthly, compared with a strain dynamometer and a piezoelectric dynamometer, the sensitive structure can be quickly disassembled and assembled, so that the range can be replaced, and multi-range measurement can be realized on the same cutter.
