Abstract
The utility model relates to a trapezoidal beam welding fixture which is characterized by comprising a lower fixed positioning base (1), screw rod vertical columns (2), an upper adjustable positioning beam (4) and an internal tension mechanism (5). A penetrating positioning threaded pin (6) is arranged on the lower fixed positioning base (1), the screw rod vertical columns (2) are arranged on two sides of the lower fixed positioning base (1), the internal tension mechanism (5) is arranged on the lower fixed positioning base (1), the upper adjustable positioning beam (4) is arranged above the internal tension mechanism (5), two ends of the upper adjustable positioning beam (4) are fixed to the screw rod vertical columns (2) through locking nuts (3), and the penetrating positioning threaded pin (6) penetrates the upper adjustable positioning beam (4) and the internal tension mechanism (5). By the aid of the trapezoidal beam welding fixture, the welding time of a trapezoidal beam is shortened by rapidly positioning, and the requirement for dimensional accuracy is met.
Description
Technical field
The utility model relates to a kind of ladder beam welding tooling.Belong to special purpose vehicle manufacturing technology field.
Background technology
Ladder beam refers to that cross section is trapezoidal beam.Lower wing plate is parallel and two coxostermums are not parallel on it.When freely welding, not only the working time long, and the height dimension of going up lower wing plate is difficult to reach requirement.Especially producing vehicle needs two ladder beam to intert when assembling.When the height dimension of ladder beam was excessive, the interspersed assembling of two ladder beam can't be carried out; When the height dimension of ladder beam was too small, though assembling easily, excesssive gap between the ladder beam of two interspersed assemblings was because the deadweight problem causes and stays.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of ladder beam welding tooling is provided, and its quick positioning function both can be saved the working time, had guaranteed dimension precision requirement again.
The purpose of this utility model is achieved in that a kind of ladder beam welding tooling, it comprises stationary positioned base down, the screw rod column, go up adjustable location crossbeam and inner strainer, described stationary positioned base down is provided with and runs through the positioning threads bearing pin, described screw rod column is arranged at down the two ends of stationary positioned base, described inner strainer is arranged at down on the stationary positioned base, described adjustable location crossbeam is arranged at inner strainer top and two ends fix by locking nut and screw rod column, and the described positioning threads bearing pin that runs through passes adjustable location crossbeam and inner strainer.
Compared with prior art, the beneficial effects of the utility model are:
A kind of ladder beam welding tooling of the utility model, it both saved the working time welding of ladder beam by quick location, had guaranteed dimension precision requirement again.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
Following stationary positioned base 1
Screw rod column 2
Go up adjustable location crossbeam 4
Inner strainer 5
Run through positioning threads bearing pin 6.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of ladder beam welding tooling, it comprises stationary positioned base 1 down, screw rod column 2, go up adjustable location crossbeam 4 and inner strainer 5, described stationary positioned base 1 down is provided with and runs through positioning threads bearing pin 6, described screw rod column 2 is arranged at down the two ends of stationary positioned base 1, described inner strainer 5 is arranged at down on the stationary positioned base 1, described adjustable location crossbeam 4 is arranged at inner strainer 5 tops and two ends fix by locking nut 3 and screw rod column 2, and the described positioning threads bearing pin 6 that runs through passes adjustable location crossbeam 4 and inner strainer 5.
Earlier ladder beam upper flange, lower wing plate are laid respectively at inner strainer 5 and go up between the adjustable location crossbeam 4, between inner strainer 5 and the following stationary positioned base 1.To go up adjustable location crossbeam 4 again and fix its position according to the requirement of ladder beam height dimension by locking nut 3, after will run through circular hole, the ladder beam upper flange preformed hole that positioning threads bearing pin 6 passes crossbeam 4 tops, adjustable location, screw in inner strainer 5, pass ladder beam lower wing plate preformed hole, be connected with following stationary positioned base 1.When running through 6 rotations of positioning threads bearing pin to following stationary positioned base 1 bottom, run through positioning threads bearing pin 6 and make with running through the inside strainer 5 that positioning threads bearing pin 6 is threaded and move upward thereby continue rotation, fit fully until ladder beam upper flange and last adjustable location crossbeam 4.Namely realize location fast, can add ladder beam two coxostermums and begin welding.
Claims (1)
1. ladder beam welding tooling, it is characterized in that it comprises stationary positioned base (1) down, screw rod column (2), go up adjustable location crossbeam (4) and inner strainer (5), described stationary positioned base (1) down is provided with and runs through positioning threads bearing pin (6), described screw rod column (2) is arranged at down the two ends of stationary positioned base (1), described inner strainer (5) is arranged at down on the stationary positioned base (1), described adjustable location crossbeam (4) is arranged at inner strainer (5) top and two ends fix by locking nut (3) and screw rod column (2), and the described positioning threads bearing pin (6) that runs through passes adjustable location crossbeam (4) and inner strainer (5).
