Description
Technical field
Patent of the present invention belongs to Auto-body manufacturing technical field, is related to vehicle body soldering positioning auxiliary, specifically a kind of body side
Enclose prepackage alignment system.
Background technology
When vehicle body soldering moulding process designs, in order to improve beat and percent of automatization, generally gusset is pre-installed and is molded
Welding is divided into two stations, and floor assembly is reached the standard grade by being transported to gusset prepackage station, and declining with elevating mechanism (reduces height just
In operation), then, left and right gusset is drawn close to above floor, and drops to precalculated position (about ± 3mm), then, by gusset hasp
(reducible ± 3mm relative motions) is pre-mounted on floor, and the vehicle body for pre-installing completion rises with elevating mechanism and is delivered to gusset conjunction
Station is spelled, vehicle body drops down onto floor positioning fixture with elevating mechanism, and left and right gusset positioning fixture is drawn close to vehicle body, and essence is carried out to gusset
It is determined that position.
In above-mentioned technical process, if differing larger with floor front and back position when gusset is pre-installed, pre- hasp lock is next, vehicle body
To when being merged station clamp alignment pin and penetrating gusset positioning hole, part is yielding；On the other hand, as it was previously stated, gusset and floor
Smaller relative motion can occur after prepackage, under the effect of gusset own wt, gusset has certain sinking with respect to floor, and alignment pin is worn
It is fashionable, equally exist part deformation problem.
To solve the above problems, generally there are two kinds of solutions：First, prepackage speed is slowed down to improve prepackage precision, together
When reduce side peripheral clamp and wear pin speed to reduce the impact to part, but the program have impact on productive temp to a certain extent；
2nd, the positioning hole with flange is designed on side wall parts with reinforced hole peripheral rigid, but adds stamping parts process and cost, and
Aperture precision is relatively low.
