The course of action of steering column for vehicles Automatic laser welding equipment of the present invention is as follows:
First, steering column pipe is put on tube supports seat, stamping parts is put simultaneously
Enter stamping parts detection tool on carry out leakage rush bound feet detection, the punching press that will have detected
Part is put on stamping parts fixed block, then, presses movement machine button, pipe detent mechanism
And each cylinder action of stamping parts clamping delivery device, Automatic-clamping steering column pipe
And stamping parts, and stamping parts propelling movement is pressed to steering column pipe side, automate
One-tenth steering column pipe docks compression with stamping parts, it is ensured that assembling parts precision, meets
High-quality, high efficiency laser welding requirement.Then, start driving source and drive rotation
Disc spins, rotates the weld jig of the steering column pipe having good positioning and stamping parts to machine
In cover, laser welding robot's action, steering column pipe and stamping parts are carried out laser
Welding, the weld jig outside fragmenting plate installs steering column pipe and stamping parts simultaneously,
After laser welding completes, driving source drives rotating disk to rotate, after laser welding again
Steering column pipe and stamping parts rotate to outside hood, the lower steering column pipe of dismounting and punching
Casting die, rotates the weld jig of mounted steering column pipe and stamping parts meanwhile
To hood, work and so forth.Realize welding while dismounting, thus improve
Labor productivity, reduces production cost, reduces labor intensity, and wherein, fragmenting plate is used
Separate inside and outside by hood, it is ensured that safety in production.Therefore, laser welding of the present invention
Middle application automatic welding clamp, has the advantage that 1) ensure each punching press zero
Assembly precision before part；2) welding product quality is ensured；3) design of welding jig is prevented
Wrong mechanism, it can be ensured that neglected loading part；4) raise labour productivity, reduce and produce
Cost；5) reduce labor intensity, it is ensured that safety in production.
Above example is referring to the drawings, carries out the preferred embodiments of the present invention in detail
Explanation.Those skilled in the art is by carrying out on various forms above-described embodiment
Amendment or change, but without departing substantially from the essence of the present invention in the case of, all fall in the present invention
Protection domain within.
