Abstract

Welding point drill bit, according to DIN 1412 shape E, is used to drill out the points at metal sheet joints in profile recesses with total length independent of being 110 mm or greater. Shaft dia. is 8.0 mm and has a driving recess to incorporate it in a pneumatic milling machine. Depending on the type of vehicle, a drill bit of pref. 110-200 mm is chosen. USE/ADVANTAGE - Designed principally for use in constructing automobile bodies, the longer shaft permits the drilling out of welding points which were previously inaccessible.

Description

Die vorliegende Erfindung geht von einem gemäß dem Oberbegriff des Hauptanspruches konzipierten Schweißpunktbohrers, nach DIN 1412 Form E, in anwendungsbedingten Gesamtlängen, hauptsächlich im Automobilkarosseriebau, aus.The present invention is based on one according to the preamble of the main claim designed spot weld drill, according to DIN 1412 Form E, in total application-related lengths, mainly in automobile body construction.

Schweißpunktbohrer mit einer Gesamtlänge ab 110 mm erlauben das Ausbohren von Schweißpunkten an Automobilen, PKW und LKW, welche aufgrund der bisherigen, handelsüblichen Schweißpunktbohrer mit einer Gesamtlänge von 80 mm unzugänglich waren.Spot weld drills with a total length of 110 mm or more allow this Drilling welding spots on automobiles, cars and trucks, which due to the previous commercially available spot weld drills with a total length of 80 mm were inaccessible.

Die Mitnehmeraussparung an dem Schweißpunktbohrerschaft ⌀ 8,0 mm erlaubt den Einsatz in offenen, pneumatischen Schweißpunktfräser­ maschinen. The driver recess on the welding point drill shaft ⌀ 8.0 mm allows use in open, pneumatic spot weld cutters machinery.  

Stand der TechnikState of the art

Im Automobilkarosseriebau werden Schweißpunktbohrer nach DIN 1412 Form E verwendet. Die Gesamtlänge dieser Bohrer lehnt sich an die Länge von Spiralbohrer der DIN 1897, 79 mm, an. Zum Ausbohren von oberflächigen oder in Profilen bis 50 mm Tiefe befindlichen Schweißpunkten ist die Verwendung dieser Länge ausreichend. Schweißpunkte in Profiltiefen über 50 mm, an den Kanten von Innenwänden, im Türbereich oder im Frontbereich können nicht mehr sauber ausgebohrt werden und sind oft nicht erreichbar. Der Anwender muß die Punkte abschleifen oder ab­ meißeln. Das hat neben den höheren Arbeitsaufwand oftmals Be­ schädigungen der unteren Bleche zur Folge. Durch die Kompakt­ heit der Handbohrmaschinen ist ein senkrechtes Bohren nicht möglich und ein Ausbrechen der Bohrerschneiden ist möglich. Schweißpunktbohrer mit einer Gesamtlänge von über 110 mm bis 200 mm im LKW - Reparaturbereich garantieren einen ausreichenden Arbeitsbereich.Spot weld drills are used in automotive body construction DIN 1412 Form E used. The total length of these drills declines the length of twist drills of DIN 1897, 79 mm. For drilling out surface or in profiles up to 50 mm Deep weld spots is the use of these Sufficient length. Spot welds in profile depths over 50 mm, on the edges of inner walls, in the door area or in the front area can no longer be drilled clean and are often not reachable. The user must grind the points off chisel. In addition to the higher workload, this often has to be Damage to the lower sheets. Because of the compact hand drilling machines is not vertical drilling possible and breaking out of the cutting edges is possible. Spot weld drill with a total length of over 110 mm to 200 mm in the truck repair area guarantee a sufficient Workspace.

Durch eine Mitnehmeraussparung im Schaftende ist es möglich, Schweißpunktbohrer mit einer Gesamtlänge ab 110 mm und Bohrer­ schaftdurchmesser von ⌀ 8,0 mm (Fig. 2), können in pneumatischen Schweißpunktfräsmaschinen eingesetzt werden.With a driver recess in the end of the shaft, it is possible to use spot weld drills with a total length from 110 mm and drill shaft diameters of ⌀ 8.0 mm ( Fig. 2) in pneumatic spot weld milling machines.

Die Gesamtlänge von 150 mm wird die gängigste Alternative zu der heutigen 79 mm Gesamtlänge werden, wobei jeder Fahrzeugtyp einen Schweißpunktbohrer für Profilschweißpunkte im Bereich ab 110 mm bis 200 mm benötigt.The total length of 150 mm becomes the most common alternative of today's 79 mm total length, with each vehicle type a spot weld drill for profile spot welds in the area required from 110 mm to 200 mm.
