Because welding gun arm is along with the increase meeting of length produces displacement in practical operation, therefore, the installed surface A of the different directions that increases and installed surface B further Butt welding gun arm reinforce, and promote the reliability and stability that welding gun arm is connected with the motion cylinder, increase the precision of practical operation.
As preferred version, piston rod is provided with a locating sleeve coaxial with piston rod outward, and an end of locating sleeve is fixedly connected with the motion cylinder, and locating sleeve and piston rod match.Positioning sleeve can further be reinforced piston rod, and the stability that increases from another point of view piston rod movement reaches radially non-deformability, thereby improves welding precision.
As preferred version, between locating sleeve and piston rod, be provided with a wear-resistant sleeve coaxial with piston rod, wear-resistant sleeve and piston rod match, and wear-resistant sleeve is fixedly connected with locating sleeve.Wear-resistant sleeve plays the effect that reduces frictional force.
As preferred version, the tube wall of locating sleeve is provided with locking hole, is provided with locking nail in the locking hole, and wear-resistant sleeve is fixedly connected with locating sleeve by locking nail.
As preferred version, the inside of wear-resistant sleeve is pore space structure, is filled with graphite in the hole.Graphite can further reduce frictional force.
As preferred version, locating sleeve and motion cylinder link are provided with positioning pedestal, and locating sleeve is connected with the motion bolt cylinder by positioning pedestal.Positioning pedestal can increase stability.
Owing to adopting technique scheme, the beneficial effects of the utility model are: promoted welding gun arm and cylinder connection reliability and stability, the stability that has improved piston rod movement reaches radially non-deformability, improved the stability of welding gun, increased welding precision, reduce trouble has improved production efficiency.
