Abstract
A system used for measuring friction stitch welding stress temperature is mainly formed by a data collector, a thermal couple, a personal computer and a foil gauge. The system adopts a semi-natural thermal couple temperature measuring method, temperature is measured by burying standard thermal couple connection points on a special portion of a welding workpiece through a drilling method when in friction stitch welding, and the foil gauge is attached onto the welding workpiece, thereby measuring change conditions of temperature and stress of certain special points on the welding workpiece. The measured temperature of the special points is converted to simulated voltage value to be transmitted to a temperature sensor of the data collector, the data collector converts a temperature signal received by the temperature sensor into figure voltage valve to be transmitted to the personal computer through an RS-232 serial port, then the PC machine analyzes and processes the received figure voltage value, and the change conditions of the foil gauge are also transmitted into the personable computer after processing of the data collector, thereby an operator can reasonably control a friction stitch welding device through the figure voltage value and relative data of stress displayed on the personable computer.

Background technology
In the friction stitch welding research process, the temperature of seam face and distribution thereof are for understanding friction welding process, research frictional heat mechanism and conduction, set up the plastic yield and the flowing law of high-temperature metal, inquire into the Mass Transfer Model in the welding process, especially the Changing Pattern of joint microstructure is significant when illustrating friction welding, in addition, since in the friction welding process, the high speed rotating of rotational workpieces, the invisibility of frictional interface, the violent plastic yield of frictional interface and near region metal thereof and the overlap of generation have brought very big difficulty all for the real-time detection of friction welding temperature with axial the shortening.Simultaneously, because the complicacy of welding process, it also is very difficult that the welding interface temperature is carried out Theoretical Calculation.Although people through unremitting effort, have had clearer and more definite understanding to friction welding joint axial temperature rule by various measurings and numerical evaluation, to the temperature at frictional interface place and radially the regularity of distribution do not obtain the result that is satisfied with yet.Therefore, it is very necessary designing a kind of brand-new friction stitch welding stress temperature measurement system.
Summary of the invention
According to background technology, the purpose of this utility model is to provide a kind of friction stitch welding device of rotating speed up to 5000 rev/mins that be used for, temperature by any point in the thermocouple measurement stitch welding workpiece, numerical value conversion through data acquisition unit is sent to PC with processing and with it, the situation of change of foil gauge is then handled through data acquisition unit and also is sent in the PC, and the demonstration that the operator can be by PC is analyzed the system that is used to measure friction stitch welding stress temperature with real-time simulation to data.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of system that is used to measure friction stitch welding stress temperature, it mainly is made of data acquisition unit (1), thermopair (2), PC (3) and paper tinsel formula foil gauge (4) four parts.The each several part mutual relationship is in this system: the native system device mainly is to adopt semi-natural thermocouple thermometry, mainly be when carrying out friction stitch welding, bury standard couple (2) contact at the weldment privileged site underground by boring method and carry out thermometric, thereby can measure the temperature and the situation of change thereof of some specified point on the weldment, and become analog voltage to be transferred to the temperature sensor of data acquisition unit (2) temperature transition of measured specified point, data acquisition unit (1) receives the temperature signal that comes with temperature sensor and is converted to digital voltage value and is transferred to PC (3) by the RS-232 serial port, PC (3) is analyzed the digital voltage value that receives and handle then, the situation of change of paper tinsel formula foil gauge (4) is then handled through data acquisition unit and also is sent in the PC (3), and the operator can reasonably control the friction stitch welding device by the digital voltage value that PC (3) shows.And this friction stitch welding device is when experimentizing, rotating speed is up to 4000r/min, welding work pieces can reach very high temperature in a short period of time, this measurement to temperature is very difficult with control undoubtedly, and by the thermopair in the native system (2) measuring more arbitrarily welding work pieces, and, the digital signal of its conversion is sent in the PC (3) by the processing and the conversion of data acquisition unit (2) to the collecting temperature data.Adjust the rotating speed of friction welding machine by the numerical value of PC (3) feedback.
Owing to adopted the technique scheme part, the utlity model has following advantage and effect:
What 1, the utility model adopted is the stress temperature measurement system, can carry out temperature survey under the hot environment that rotating speed produced of friction device up to 4000r/min.
2, the utility model accuracy of measurement height, irrelevant and can measure the temperature of any point in the welding work pieces with material.
The temperature variation of welding work pieces and the state of workpiece when 3, the present invention can clearly observe friction stitch welding by PC.
4, the utility model has adopted paper tinsel formula foil gauge, and radiating condition is good, the permission electric current is big, transversal effect is little, fatigue lifetime is long, production run is simple, comparatively is suitable for the high-speed friction weldering.
