摘要:
The present invention relates to a method and an auxiliary device for precision positioning of welded type nozzles. The auxiliary device for precision positioning of welded type nozzles includes a plurality of alignment tips and an alignment bar. Each alignment tip is connected to a welding adapter and extends a distance. The alignment bar is combined with the alignment tips so that first positioning portions of the alignment tips are aligned with a plurality of second positioning portions of the alignment bar, and after the alignment bar is combined with the alignment tips, a correction distance between an end surface of the alignment bar and a center line of a main pipe header in a longitudinal direction is larger than a length of an assembled nozzle after a nozzle tip is combined with the corresponding welding adapter. In this way, the geometric positions of the nozzles can be accurately corrected.

An adjustable supporting stand includes a main body with a receiving room, a slidable module disposed in the receiving room, a supporting holder assembled on the slidable module, a gear set connected to the supporting holder, and an elastic member disposed on the main body. The gear set has at least one first gear and a second gear, and the first gear is smaller than the second gear. One end of the elastic member is fixed on the main body and another end of the elastic member is connected to the second gear.

A holding apparatus has a main body, a longitudinal clamping member, and second and third clamping members. The first clamping member is slidably disposed on the main body, and the first clamping member has at least one pair of slanted sliding-tracks. The transverse clamping members are slidably disposed on the main body each having at least one sliding element slidably coupled to the slanted sliding-track of the longitudinal clamping member.

An adjustable display mounting bracket assembly includes a mounting bracket, a linkage unit, and a fixing plate. The mounting bracket includes a main body, at least one first connecting member, at least one second connecting member, and a support body. The first and second connecting members are pivotally connected to the main body and the support body. The second connecting member can slide relative to the main body for adjusting the mounting bracket. The linkage unit is pivotally connected to the mounting bracket on one end and the fixing plate on opposite end. The linkage unit allows the distance between the mounting bracket and the fixing plate to be adjustable.
