Abstract
A method for controlling the phase of the part to be welded by friction includes processing the acquired information by computer to issue instruction at a determined phase, and pulling up a locating pin which can limit the relative rotation of dual-layer spring fixture to make the moving end of welded part rotate freely. As a result, the rotating end and moving endo f welded part can rotate with mainshaft. Its advantages are high phase correstness, low noise, no impact and high weld quality.
Description
Technical field:
The present invention relates to a kind of friction welding part phase control method.
Background technology:
Existing friction welding phase controlling all be with round end brake point accurately be controlled to be starting point, derive two kinds of concrete grammars: electric mechanical forces location and electronics DC injection braking to be located.
Electric mechanical is forced localization method, sees that the patent No. is Britain's patent of invention " Continuous drivefriction welding machine " specification of GB2084499A.Computer sends instruction after detecting the speed of mainshaft and dropping to definite value, start the phase detent mechanism and put down position block, blocks the cam on the rotating main shaft, makes main shaft force to stop operating in the phase place that is limited.Its advantage is the positioning accuracy height, and shortcoming is to have bigger impact, is unfavorable for the performance of joint and the life-span of welding machine.
Electronics DC injection braking localization method sees that Wang Xingbin is at the 8th whole nation welding second 2-280 page or leaf of proceeding " phase place friction welding technological and equipment research " literary composition.It is in the brake stage, detects the speed of mainshaft and has dropped to after the setting, sends instruction by computer, starts frequency converter and carries out DC injection braking, and accurately control braking angle realizes location mutually.This method does not have impact, but because in the final stage of braking, the speed of mainshaft is little, and moment of torsion is very big, the moment that frequency converter produced has been difficult to the generation effect, makes that the phase controlling precision of actual welding is lower.In addition, reverse the welding quality that also influences joint easily in the pressure of low thermophase.
Above-mentioned two kinds of friction welding part phase control methods, all be to adopt round end to force the location, not only the phase controlling precision is lower, and impact that friction-welding machine and weldment are subjected to or pressure are reversed bigger, also there is bigger impact noise, influences the welding quality of joint to a certain extent.
Summary of the invention:
The object of the invention provides a kind of friction welding part phase control method; accurately locating mutually when adopting " taking advantage of a situation " control to reach brake reaches the phase controlling purpose with friction-welding machine mobile terminal method for releasing, can effectively avoid impacting or force and reverse; improve welding quality, the protection friction-welding machine.
A kind of friction welding part phase control method, it is characterized in that: after the friction process of friction welding finishes, computer 1 sends instruction, clutch 4 is thrown off, motor 3 breaks away from main shaft 16, brake 17 work, information gathering and instruction output system 7 is sent main shaft 16 rotating speeds and phase information that photoelectric encoder 6 is collected into computer 1, computer 1 is handled the information that obtains, send instruction at the phase place place that determines, start the motor mechanism 8 of pulling pin, extract and limiting double-layer spring anchor clamps 10 alignment pin 9 in relative rotation, recover weldment mobile terminal 15 rotation freedom, make between weldment round end 14 and the weldment mobile terminal 15 no longer to relatively rotate, but finish last rotation with main shaft 16 jointly, thereby realize locating mutually accurately.
In the friction heating process of friction welding, computer 1 sends instruction, connects power supply 18, electromagnetism winding 20 electric back electromagnetic clutch 19 close and, rotate restriction weldment mobile terminal 15; After the friction heating process of friction welding finishes, computer 1 is handled the information that obtains, send instruction at the phase place place that determines, deenergization 18, make electromagnetism winding 20 dead electricity, electromagnetic clutch 19 is opened under the effect of spring 22, makes between weldment round end 14 and the weldment mobile terminal 15 no longer to relatively rotate, but finish last rotation with main shaft 16 jointly, thereby realize locating mutually accurately.
Compare with prior art, reach the phase controlling purpose, accurately locating mutually when utilizing " taking advantage of a situation " control to realize brake with friction-welding machine mobile terminal method for releasing; can avoid effectively impacting or force and reverse, reduce noise, improve welding quality; prolong the welding machine life-span, the protection friction-welding machine.
