Aforesaid grab rail base registration device, wherein, base template can directly be welded on the location division, and also detouchable is fixed on the location division.
When but the base template detouchable is fixed on the location division, can be provided with through hole on the described location division;
Described grab rail base registration device also can comprise:
Attaching parts is used for by described through hole described base template being fixed on described location division, so that the base template on the grab rail base registration device is detachable, thereby can be used in the base location of different size, realizes repeated usage, to make full use of resource.
Described through hole can have two, and the two width between centers equals the width between centers of two tapped bore on the grab rail base to be positioned, so that base template being connected on the positioning support of fastness more.
Can be provided with two tapped bore that are complementary with grab rail base to be positioned on the described base template;
Described attaching parts can be with described base template on the bolt that is complementary of tapped bore.
Can be provided with spring washer between described attaching parts and the described through hole, as spring washer, to play further fastening effect.
Can be provided with flat gasket between described attaching parts and the described through hole.
The grab rail base registration device that the utility model provides, the distance of grab rail base to be positioned and car body being walked between the panel edges by positioning support limits, mark the outline line of grab rail base to be positioned by base template, realized quick, the accurate location of grab rail base, simplified operating sequence, save a large amount of surveying works, improved accuracy of positioning, avoided waste of manpower resource.
