Description
Technical field
The invention belongs to cutting technology field, relate to the comprehensive detection system that a kind of cutting force, cutting temperature, vibration and Noise Synchronization are measured in real time, particularly a kind of hard state turning machine stability comprehensive detection system.
Background technology
Hard state turning technology is a kind of novel processing technique ground with car generation, when implementing hard state turning process, cutting force is big, cutting temperature is high, vibration is big, noise is big, these factors have important impact to component shaping precision, surface quality, cutting-tool's used life etc., therefore, measure cutting force real-time and accurately, noise that cutting temperature, cutting vibration and cutting produce is by significant to improving the crudy of workpiece, tool life.
Measuring the commonly used piezoelectric force transducer of cutting force at present, its installation form mainly has: is arranged on knife rest or is arranged between blade and handle of a knife.There is Railway Project in above-mentioned both cutting force measurement devices: one is susceptible to the interference of system vibration；Two is that installation difficulty is big, will improve the structure of machine tool component.
Measuring method to cutting temperature has and mainly has thermocouple method and light, radiant-heat method at present, thermocouple method is used when measuring cutting temperature, to need to bore at the measured point of cutter an aperture, this not only wastes time and energy, also can affect the distribution of hot-fluid, it is not the most accurate for making to measure, light, radiant-heat method are often limited by the sensor specifically scope of arranging, it is impossible to directly obtain the temperature within cutting zone.
The apparatus system that the Noise Synchronization produced cutting force, cutting temperature, cutting vibration and cutting at present measures and exports in real time have not been reported.
Summary of the invention
It is an object of the invention to provide and a kind of can measure the comprehensive detection system of noise that cutting force, cutting temperature, cutting vibration and cutting produce by real-time synchronization in hard state turning.This system applied range, simple in construction, comprehensive by force, simple to operate.This device may be used for lathe or turning center.
For achieving the above object, a kind of hard state turning machine stability comprehensive detection system of the present invention includes blade, handle of a knife, backing plate, SMD pressure transducer, film platinum resistor temperature sensor, noise detector, vibration-detecting instrument, temperature signal modular converter, force signal modular converter, computer.Described backing plate is placed between blade and handle of a knife, the groove of placement force sensor and temperature sensor is had on backing plate, SMD pressure transducer and film platinum resistor temperature sensor are respectively placed in the groove of correspondence, blade is placed on above pad and locks with pressing plate, signal is changed by pressure transducer and temperature sensor by signal conversion module, last signal is transferred on computer show, vibration-detecting instrument and noise detector are respectively placed in the both sides of knife rest, transfer signals to computer by guide line.Described knife rest is installed the side of vibration-detecting instrument and is had aperture, and the probe of vibration-detecting instrument stretches into aperture and measures.
The shape of above-mentioned groove and the degree of depth are determined by temperature sensor and pressure transducer respectively, and with temperature sensor, pressure transducer shape, the most identical.
The actual gain of the present invention is: be widely used, it is only necessary to be installed on corresponding handle of a knife just can use opening reeded backing plate, easy for installation, simple to operate, with composite measurement cutting force, cutting temperature, cutting vibration and noise, and can be monitored in real time.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As depicted in figs. 1 and 2, a kind of hard state turning machine stability comprehensive detection system of the present invention, mainly by 1 pressing plate, 2 handle of a knifes, 3 blades, 4 film platinum resistor temperature sensors, 5 backing plates, 6 SMD pressure transducer compositions.
As shown in Figure 2, cutter front end, backing plate it is placed with between blade and handle of a knife, two grooves are had on backing plate, the shape size of two grooves is identical with 4 film platinum resistor temperature sensors and 6 SMD pressure transducers respectively, it is respectively intended to place two sensors, such that it is able to obtain cutting temperature and Cutting Force Signal.After placing 4 film platinum resistor temperature sensors and 6 SMD pressure transducers, blade is fixed by 1 pressing plate.
As it is shown in figure 1, the signal obtained of temperature sensor is by wire transmission to temperature signal modular converter, it is converted into the signal calculating function identification, then by wire transmission to computer, shows real-time cutting temperature by corresponding software；The force signal that force transducer obtains, by wire transmission to force signal modular converter, is converted into the signal calculating function identification, then by wire transmission to computer, shows real-time cutting force by corresponding software；On knife rest, side connects vibration-detecting instrument, and opposite side connects noise detector, connects and needs out an aperture on a side tool post of vibration-detecting instrument, makes the probe of vibration-detecting instrument stretch in aperture and measure.The digital signal that vibration-detecting instrument and noise detector obtain can be transmitted directly to computer.
Use present system that these signals of noise produced in the cutting force in hard state turning, cutting temperature, cutting vibration and cutting are the most all transferred to computer, such that it is able to cutting force, cutting temperature, cutting vibration and noise are carried out real-time detection, there is the features such as real-time, quick, comprehensive.
