Abstract
The invention relates to a moveable pin device and a method using the same to weld a vehicle body in order to achieve the rapid processes of welding and locating and facilitate the welding process. The technical scheme of the invention is as follows: a shoulder is arranged at the lower part of the moveable pin and located inside the base of the moveable pin; a moveable clearance is left between the outer side of the shoulder and the inner wall of the base of the moveable pin; and for the shoulder of the moveable pin is capable of freely rotating in the base of the moveable pin, the end part of the moveable pin can enter a hole on the vehicle body for welding and locating, particularly, a nut can be welded by placing the nut to be welded on the moveable pin.
Description
Technical field
The present invention relates to a kind of method of utilizing the removable pin device to carry out automobile body welding.
Background technology
In the automobile welding procedure, very high to the position degree and the required precision in hole, but the part product has brought influence to a certain degree for the automobile body welding quality because Sheet Metal Forming Technology can't guarantee the position degree and the precision in hole.
In the prior art, be that (patent No.: 200620092880) disclosed technical scheme, what adopted the welding location is steady pin to " positioner in the body in white welding tooling " patent like denomination of invention.As shown in Figure 2, steady pin is adopted in the welding location, if there is a point deformation in the vehicle body aperture, just possibly cause pin and hole to mate, and especially when producing in batches, also can have influence on production efficiency; And this steady pin requires the position degree and the precision in hole on the vehicle body very high, therefore; In design process, require the punching on the vehicle body that position degree and precision very accurately will be arranged; Increase design difficulty, even can increase the operation content of mould, thus the manufacturing cost of increase mould.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of method of utilizing the removable pin device to carry out automobile body welding, can the Rapid Realization welding locate convenient welding.
Realize the technical scheme of the object of the invention:
A kind of method of utilizing the removable pin device to carry out automobile body welding; The removable pin device comprises removable pin, removable pin pedestal, and the removable pin bottom is provided with convex shoulder, and this convex shoulder is positioned at the removable pin pedestal; Leave the free gap between the convex shoulder outside and the removable pin base internal wall; The removable pin convex shoulder can freely rotate in the removable pin pedestal, it is characterized in that: utilize removable pin convex shoulder rotating freely in the removable pin pedestal, the location is welded in the hole that the removable pin end is passed on the vehicle body; The nut of need welding is put on the removable pin, nut is welded.
Free gap size range between the removable pin convex shoulder outside and the removable pin base internal wall is 0.5mm-1.5mm.
Removable pin pedestal bottom is connected to fixedly panel seat of removable pin.
The beneficial effect that the present invention has:
Because removable pin of the present invention bottom is provided with convex shoulder, and convex shoulder can rotate freely in the removable pin pedestal, therefore; But the welding location is realized in the position, hole on the removable pin rapid alignment centering vehicle body, thereby convenient welding; Effectively enhance productivity, guarantee the precision of welded nut and installing hole.Simultaneously, but because removable pin of the present invention through rotating freely the position, hole on the rapid alignment centering vehicle body, need not have too high specification requirement to the position degree and the precision of body cutout, greatly reduce the difficulty of vehicle body Sheet Metal Forming Technology, thereby reduce production costs.
Description of drawings
Fig. 1 is the structural representation of removable pin device of the present invention;
Fig. 2 is the structural representation of steady pin in the prior art.
The specific embodiment
As shown in Figure 1, the bottom of removable pin 2 is provided with convex shoulder, and this convex shoulder is positioned at removable pin pedestal 3, leaves the free gap between the convex shoulder outside and the removable pin base internal wall, and the removable pin convex shoulder can freely rotate in the removable pin pedestal.Free gap size range between the removable pin convex shoulder outside and the removable pin base internal wall is 0.5mm-1.5mm, and in the present embodiment, the free gap is of a size of 0.8mm.The bottom of removable pin pedestal 3 is connected to fixedly panel seat 1 of removable pin.
Utilize removable pin convex shoulder rotating freely in the removable pin pedestal, make removable pin aim at centering body cutout position automatically, the location is welded in the hole that the end of removable pin is passed on the vehicle body, and the nut that need are welded is put on the removable pin, and nut is welded.
In another preferred embodiment of the present invention, the free gap between the removable pin convex shoulder outside and the removable pin base internal wall is of a size of 1.2mm.
Claims (3)
