Constantan wire lead -out wire and work piece material are kept away from the one end of processing district and are connected charge amplifier, and charge amplifier connects data collection card, data collection card linked computers. The utility model discloses temperature easy operation is milled in the measurement, and convenient to use can in real time, fast, accurately measure cutting temperature, and measurement accuracy is high, and is with low costs.
Description
Technical field
The utility model relates to a kind of measurement mechanism of cutting temperature, especially a kind of Milling Temperature measurement mechanism.
Background technology
Titanium alloy is because specific strength is high and coefficient of heat conductivity is little, and Milling Temperature is higher.Understand the distribution of titanium alloy Milling Temperature and Changing Pattern thereof, have important meaning for the research of titanium alloy cutting processing mechanism, the design and manufaction of cutter and the selection etc. of Cutting Parameters.
The measuring method of Milling Temperature is more, mainly contains natural thermocouple method, artifical Thermocouple method, thermal infrared imager method etc.These methods respectively have feature, but all there is certain deficiency, weak point mainly contain following some:
1) natural thermocouple method can only measure the medial temperature in milling region, can not record the temperature of milling Region specification point, is not suitable for the kelvin rating accurately measuring cutting zone.
2) artifical Thermocouple method needs pre-manufactured hole on cutter or workpiece to carry out measuring tempeature distribution, except increasing difficulty of processing, also can affect the Temperature Distribution of cutter or workpiece because of the existence in hole, limit applying of the method.
3) thermal infrared imager thermometry can carry out remote non-contact monitoring, but is limited by the complicacy of material surface radiance parameter, have impact on the measurement of measurand actual temperature, often can add liquid coolant in process, also can affect the accuracy of infrared measurement of temperature.
Utility model content
In view of prior art Problems existing, the utility model provide a kind of can in real time, fast, the titanium alloy Milling Temperature measurement mechanism of Measurement accuracy cutting temperature.
The utility model solves the technical scheme that its technical matters adopts: a kind of titanium alloy Milling Temperature measurement mechanism, comprises titanium alloy workpiece, insulation course, constantan wire, charge amplifier, data collecting card and computing machine; Titanium alloy workpiece is divided into two parts, and by clamp; Insulated by insulation course between constantan wire and workpiece; Constantan wire extension line and workpiece material are connected charge amplifier, charge amplifier connection data capture card away from one end of processing district, and data collecting card connects computing machine.
Described constantan wire is flat pattern, passes in the horizontal direction from workpiece.
Described computing machine is provided with data collecting card and temperature acquisition interface.Principle of the present utility model is: titanium alloy workpiece material and constantan wire partner thermopair, and the extension line of constantan wire connects a pole of charge amplifier, workpiece material away from another pole of a termination amplifier of processing district, simultaneously also as the cold junction of thermopair.When milling is carried out, constantan wire is cut off, and the insulation course between constantan wire and workpiece is destroyed, and forms a transient heat contact, forms the hot junction of thermopair, and cold junction forms the temperature difference, thus produces thermoelectrical potential in loop.This thermoelectrical potential signal is after charge amplifier amplifies, the digital signal being convenient to analyze is converted to by A/D conversion equipment, then by the data collecting card collection on computing machine, the Signal aspects gathered, to the temperature acquisition interface calculated, completes the process that Milling Temperature is measured.
The effect that the utility model is useful is: titanium alloy Milling Temperature measurement mechanism of the present utility model, and structure is simple, and easy to use, can measure Milling Temperature real-time, quickly and accurately, measurement effect is good, measures efficiency high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1, insulation course; 2, titanium alloy workpiece; 3, milling cutter; 4, constantan wire; 5, charge amplifier; 6, data collecting card; 7, computing machine.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: the Milling Temperature measurement mechanism in the present embodiment, comprises insulation course 1, titanium alloy workpiece 2, milling cutter 3, constantan wire 4, charge amplifier 5, data collecting card 6 and computing machine 7.Constantan wire 4 extension line and workpiece material 2 are connected charge amplifier 5, charge amplifier 5 connection data capture card 6 away from one end of processing district, and data collecting card connects computing machine 7.
Titanium alloy workpiece 2 is divided into two parts and uses clamp, and constantan wire 4 passes in the horizontal direction from workpiece.Constantan wire, to be insulated by insulation course between workpiece and fixture.Computing machine is provided with data collecting card and temperature acquisition interface.
During use, milling feed direction is vertical with constantan wire 4 direction.When the milling edge of milling cutter 3 is through constantan wire 4, the insulation course 1 between constantan wire and workpiece is destroyed, and forms a transient heat contact, forms the hot junction of thermopair.Other one end of constantan wire 4 and workpiece 2, because distance milling region is comparatively far away, temperature changes hardly, forms the cold junction of thermopair.So just constitute a thermopair by workpiece and constantan wire, hot junction and cold junction form the temperature difference, thus produce thermoelectrical potential in loop.This thermoelectrical potential signal, after charge amplifier 5 amplifies, transfers on data collecting card 6, then shows to the temperature acquisition interface on computing machine 7.According to the size of the thermoelectrical potential collected, contrast with the numerical value demarcated in advance, just can draw the cutting temperature in milling district.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
