Abstract

The invention relates to a process and device for welding motor vehicle body components, in which, at first the components are positioned with each other oppositely in the preparing table outside of welding bench, then the components are taken out from the preparing table and sent to the welding bench via robot under condition of keeping assured relative position, where the components are welded with each other. So the device can avoid the required positioning auxiliary device in the welding bench area based on the prior art, thereout realizing simplification and improving flexibility greatly.

Description

The method and apparatus that is used for the welded body member
Technical field
The present invention relates to a kind of a plurality of methods that are given for the member of vehicle body that are used to weld, each member is at first located in prep stand, sends into welding bench and then welding.In addition, the invention still further relates to a kind of equipment that is used to implement this method.
Background technology
A kind of such method is the object of DE69502734T2.In prep stand, be positioned in case or the pallet according to the method member, and then send into welding bench by conveying device.Welding is positioned at the member in case or the pallet in welding bench.In blanking time in prep stand another case of clamping or pallet.Can handle different schemes by using different casees or pallet at this.
At this in fact disadvantageously, member enters welding bench with case.Therefore welding bench must adapt to chest about its size and material movement.Though son can form a unified one about its external dimensions, so that also can process different members in welding bench.And required a large amount of chests exactly prove disadvantageous in the vehicle body of complexity, and particularly flexible manufacturing thus especially comprises such member that can not use chest to carry, the difficulty that becomes or impossible.Can not realize simplifying by using such pallet at this, wherein each member separated by pallet and thereby import next station independently because need the loading platform or the discharging platform that are used to reorientate thus respectively.
Also carry each positioning framework of harmonizing according to member by similar mode in according to the equipment of DE69008839T2, member is positioned in this positioning framework and welding.Welding process is undertaken by robot, and wherein welding procedure is harmonized according to corresponding member.Wherein a plurality of members of parts can at first need not be positioned in the positioning framework fixedly connectedly and connect soldered.
To this positioning framework proof also is disadvantageous, because in order to realize desired material movement, need change positioning framework and also need to change welding bench in case of necessity when changing production routine thus.
By DE19914125A1, DE19917908A1 and DE4113295A1 also other equipment and method as can be known,, used positioning framework equally wherein for member is imported welding bench.
Summary of the invention
Drawing task of the present invention by such background technology is, implements the method for the described type of beginning like this, even its flexibility that can simplify process and realize significantly improving.A kind of equipment that is used to implement this method should be provided in addition.
Above-mentioned task solves like this according to the present invention, and promptly member separates and the input welding bench from prep stand by means of robot or automatic pilot under the situation of the position toward each other that keeps determining by prep stand.Welding process in this welding bench need not use clamping frames or other auxiliary locator to implement, and can improve flexibility significantly thus.Because particularly also cancelled the welding bench of on auxiliary locator, harmonizing that needs originally thus.At first in prep stand, determine the position toward each other of member and then transfer robot at this in this position, keep preposition reliably by robot, reorientate each other and need not for this reason in the zone of welding bench member, significantly reduce floor space thus simultaneously.In addition, also can process the member of special size neatly, not operate and can expand arbitrarily thus because welding bench can rely on according to the required positioning framework of prior art.
Described second task, promptly provide a kind of be used to implement this method be used for the welded body member comprise that one is given for the equipment of the prep stand of member location, pass through a robot or automatic pilot solution according to the present invention, under the situation of the position toward each other that keeps determining, can separately and the welding process in the back fix from prep stand by prep stand by this robot or automatic pilot member.Member is positioned in the prep stand in the welding bench outside and then forwards on robot or the automatic pilot thus.Therefore in welding bench, need not reorientate member, wherein simultaneously can abandon in welding bench, using unfriendly auxiliary locator.Welding bench can obviously be simplified and operation neatly thus.
A kind of particularly advantageous embodiment of the present invention also can be realized like this, be that prep stand has a container that is used for member, this container is arranged on movably from the primary importance that is given for the member location member is forwarded on the guide rail of the second place that is given for robot or automatic pilot.At this, member is transported near the welding bench by means of container and is held by robot on demand and remain in the welding bench.Container can be given for other members of position clamping of location in welding process.Can further optimize work flow thus.
Also special in addition practically, prep stand is equipped with a plurality of containers that are used for special different component of using selected.Thus can be with the interchangeable member arbitrarily that sequentially welds almost in identical welding bench.For these needs change control program, and can abandon changing the tool of production or manual intervention.
Another special structure in conjunction with reality of the present invention can realize like this that also promptly robot or automatic pilot are arranged on the guide rail movably.Can enlarge the working space of equipment thus significantly, produce very complicated parts so that also can structurally change equipment in this way.
Particularly advantageous is that this equipment has at least one robot that disposes plumb joint.At this, not only location but also welding process are all finished by robot, can further improve processing flexibility thus.The particularly different robots that are used for fixing with welded unit can move relative to each other like this, make it possible to change be clamped in one independent operation all required zones of welding.
This a kind of further formation proved also special member is a gusset plate that is made of a plurality of parts in conjunction with actual, in this gusset plate because external dimensions requires one correspondingly to the welding bench of its adjustment according to prior art.This gusset plate this can be by for example disposing the suction-type grappling fixture robot fixing reliably and in independent operation, be welded into body of a motor car together with base plate part, roof rail and opposite side coaming plate jointly.

Claims (7)
