Abstract
The invention supplies a welding displacement control method for a clamp of a pipe. Firstly, the upper welding head and the lower welding head of the welding device are both equipped with encoders; and then at the same time, the encoders will send impulse signals continuously to a servo control system in a welding process, so that the servo control system will control the welding displacement; finally when the welding displacement approaches a preset standard displacement, and the servo control system will automatically stop the welding process. According to the invention, the encoders on the welding head send the impulse signals to the servo motor so as to control the welding displacement with high accuracy.
Description
Technical field
The present invention relates to a kind of weld displacement control method of pipe fitting clip, relate in particular to a kind of weld displacement control method of controlling the pipe fitting clip of weld displacement through servo-control system.
Background technology
As everyone knows, it is the development in future direction that the automation of mechanical part is installed, but does not still realize full-automatic the installation in the production process of at present many parts, still needs the operating personnel of some to monitor and manual operation.
For the installation of pipe fitting clip class mechanical part, at present in the production equipment automation erection unit is arranged seldom, very low on the efficient of producing also can waste many manpowers and time simultaneously; Even some automation erection units are arranged; Also be that first installation process with pipe fitting clip class mechanical part splits into some roads installation procedure; For the corresponding automation mounting production line of each road installation procedure design, just after accomplishing one procedure, semi-finished product need be changed process equipment again then; Carry out next process, and need operating personnel to operate accordingly in the replacing process.So just make operating equipment complicated, need design corresponding processing equipment, secondly, still need the operating personnel of some to operate in the whole machining process process, also have the whole erection process not smooth, influenced production efficiency for each procedure.
And most pipe fitting clip class mechanical part in installation process, to keep away unavoidable be exactly to weld this step; The part welding still needs operating personnel's manual operation to weld in the welding technology field at present; So both reduced production efficiency, the serious accident that the danger in the time of simultaneously also can be owing to welding causes casualties.Even some equipment have possessed automation welding function; Great majority are through supercharge cylinders in the welding process; And then pipe fitting clip class mechanical part welded; The defective of supercharge cylinders is exactly a pressure inaccuracy in the pressurization; There is bigger difference in the product of accomplishing for welding, and can directly cause in the welding process then feeling simply helpless especially for the demanding pipe fitting clip of some welding precisions class mechanical part directly with pipe fitting clip class mechanical part burn-through just because of the inaccuracy of pressure in the supercharge cylinders process.
So just be badly in need of a kind of welding that can realize full-automatic process, can realize the welding method of High Accuracy Control weld displacement again.
Summary of the invention
In order to solve the problems of the technologies described above; The invention provides a kind of weld displacement control method of pipe fitting clip, this displacement control method is provided with encoder on last soldering tip and following soldering tip, in the welding process; Encoder can constantly send pulse signal to servo-control system; Accurately measure weld displacement, weld displacement stops welding immediately when reaching predefined standard value, and this method welding precision is high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of weld displacement control method of pipe fitting clip, concrete operations are following:
On soldering tip on the welder and following soldering tip, encoder is set all;
In the process of welding, the encoder of last soldering tip and following soldering tip can send pulse signal to servo-control system simultaneously and constantly, and servo-control system can be measured the weld displacement of soldering tip and following soldering tip through pulse signal;
When weld displacement reached predefined standard shift value, servo-control system can stop welding process automatically.
The present invention compared with prior art has following beneficial effect:
The weld displacement control method of a kind of pipe fitting clip provided by the invention is sent pulse signal and then is controlled weld displacement to servo-control system through the encoder on the soldering tip, and precision is high.
Description of drawings
Fig. 1 is a control flow chart of the present invention.
The specific embodiment
Come the present invention is further set forth through the specific embodiment below: (like Fig. 1)
The weld displacement control method of a kind of pipe fitting clip that this implementation method provides, concrete operations are following:
On soldering tip on the welder and following soldering tip, encoder is set all;
In the process of welding, the encoder of last soldering tip and following soldering tip can send pulse signal to servo-control system simultaneously and constantly, and servo-control system can be measured the weld displacement of soldering tip and following soldering tip through pulse signal;
When weld displacement reached predefined standard shift value, servo-control system can stop welding process automatically.
The weld displacement control method of a kind of pipe fitting clip that this embodiment provides sends to servo-control system through the encoder that is arranged on the soldering tip with pulse signal; Servo-control system and then monitor the weld displacement of soldering tip accurately; When weld displacement reached predefined standard value, servo-control system stopped welding process automatically, in the whole welding process; Servo-drive system is controlled the welding displacement energy enough accurately, can satisfy various high-precision welding.
To those skilled in the art; Obviously can recognize that above-mentioned specific embodiment is a preferred version of the present invention; Therefore the improvement that possibly make the institute of some part among the present invention of those skilled in the art changes; That embodies is still principle of the present invention, realization be still the object of the invention, the scope that all belongs to the present invention and protected.
