Description
Technical field
The present invention relates to a kind of static shaft shoulder agitating friction weldering that can in real time measure welding temperature, specifically a kind of to pass through light
Fiber sensor and infrared radiation thermometer are realized carrying out setting for real-time monitoring to the distribution of static shaft shoulder agitating friction weldering field of welding temperature
It is standby.
Background technology
Agitating friction weldering be mutually moved using workpiece end face, the heat produced by phase mutual friction, make end reach thermoplasticity
State, then rapid upset, completes a kind of method welded.Stirring soldering tip is the crucial and core component of agitating friction weldering, main
There are the shaft shoulder and mixing needle two parts to constitute.The Main Function of the shaft shoulder is that frictional heat wraps plastic zone metal as far as possible, is formed
The welding surroundings of one closing, and the Plastic Flow of adjacent material is driven to form joint.In convention stir friction welding (FW), the shaft shoulder
It is main heat production mode with the friction between soldered material.Static shaft shoulder agitating friction weldering is a kind of new agitating friction
Welding technology, in welding process, internal mixing needle is in rotation status, and the outside shaft shoulder is not rotated, and only advances along welding direction.
The presence of the static shaft shoulder, can not only reduce overlap, while suppressing plastifying material from the mixing needle both sides extrusion for rotating, prevent hole
Etc. the formation of defect.But, either the static shaft shoulder agitating friction weldering of high rotating speed, conventional rotating speed or angle welding, is all present
The abrasion of stirring-head and problems of excessive heat.
In addition, the real-time detection of each item data of welding process is to realize the basis of intellectually and automatically.Improve welding matter
The key of amount, one is the uniformity for improving face temperatures fields, two be control in welding process the intensification of welded part with it is cold
But speed.Therefore real-time detection and control welding temperature are the developing most important problems of solder technology.In the last few years, it is domestic
Some outer Welder authors have carried out the research work of welding temperature context of detection, but achievement in research and practical application gap
It is larger, thus field of welding temperature real-time detection technology is one of the international advanced subject for being badly in need of solving in welding technology field.Mesh
The temperature checking method of front main flow is mainly measured using thermocouple, and this method can only be used in an experiment, it is impossible to real
Now measurement is carried out to each piece of product, also ongoing welding parameter cannot be adjusted by real-time status monitoring,
Closed-loop control is realized, optimizes welding quality.
The content of the invention
For the problem that current welding temperature detection method is present, the present invention proposes that one kind is provided with welding temperature measurement apparatus
Static shaft shoulder agitating friction weldering.
To achieve these goals, present invention employs technical scheme below：
A kind of static shaft shoulder agitating friction weldering that can in real time measure welding temperature, on the static shaft shoulder of the agitating friction weldering
Welding temperature measuring system is installed, the welding temperature measuring system includes support ring, the heat to measure stirring-head temperature
Galvanic couple and multiple infrared temperature sensors to measure weldment temperature, the support ring is fixedly set on the static shaft shoulder, respectively
The uniform annular spread of optical fiber sensor head of individual infrared temperature sensor is fixed in support ring and is connected to switch board by optical fiber,
Thermocouple is fixedly mounted in support ring and is connected to switch board by wire.
Compared with prior art, the beneficial effect that the present invention possesses：
The present invention can realize measuring static shaft shoulder agitating friction weldering welding temperature in real time, and feed back to lathe
Control section, improves the weldquality of agitating friction weldering.
Description of the drawings
Fig. 1 is the profile of the static shaft shoulder agitating friction weldering that can in real time measure welding temperature of the present invention.
In figure, 1, the static shaft shoulder, 2, thermocouple, 3, optical fiber sensor head, 4, support ring, 5, the little shaft shoulder, 6, mixing needle.
Specific embodiment
Technical scheme is further elaborated below by embodiment.
Embodiment 1
A kind of agitating friction weldering of the static shaft shoulder 1 that can in real time measure welding temperature, its feature is, the agitating friction weldering
The static shaft shoulder 1 on welding temperature measuring system is installed, the welding temperature measuring system includes support ring 4, to measure
The thermocouple 2 of stirring-head temperature and multiple infrared temperature sensors to measure weldment temperature, the support ring 4 fixes suit
On the static shaft shoulder 1, the uniform annular spread of optical fiber sensor head of each infrared temperature sensor be fixed in support ring 4 and by
Optical fiber is connected to switch board, and thermocouple 2 is fixedly mounted in support ring 4 and by wire and is connected to switch board.
Operation principle：
When agitating friction weldering weldering bed works, mixing needle 6 and the little shaft shoulder 5 rotate at a high speed, produce with wlding generation friction a large amount of
Heat, makes wlding be melted into semifluid, and two pieces of wldings are merged after cooling.The static shaft shoulder 1 and welding temperature fixed thereon
Measuring system is not rotated all the time, but together edge moves closely to direction with machine tool chief axis.The bottom surface and wlding of the static shaft shoulder 1
Come in contact and rub, play a part of to extrude wlding.The bottom surface of support ring 4 1～10mm higher than the big shaft shoulder or so, with avoid with
Wlding comes in contact.During welding, the multiple optical fiber sensor heads being evenly distributed in support ring 4 are while what capturing material itself sent
Infrared ray, and the infrared temperature sensor being delivered to by optical fiber in switch board, are converted into temperature data.According to corresponding
The position of optical fiber sensor head can draw out the time dependent situation in temperature field, for evaluating the weldquality of welding, and butt welding
The temperature and time of the tempering process of seam provides guidance.According to the temperature conditions of each sensor feedback, it can be determined that go out sweating heat
The size of the zone of influence, can adjust accordingly the parameters such as rotating speed, the feed speed of main shaft, improve weldquality, and saving energy consumption also may be used
To provide reference to follow-up tempering process.Thermocouple 2 prevents stirring-head from occurring overheated and right to measure stirring-head temperature
Abrasion condition is estimated.
