A kind of drilling combination tool and using method

Abstract

The invention belongs to the technical field of forming sheet metal parts, and in particular relates to a drilling combination tool and a use method for drilling an end face with an asymmetric cylinder. For parts that have no obvious features as a positioning function, the drilling plate cannot be accurately positioned with the part to make holes. The combined tool for drilling in the present invention includes a positioning clamping plate and a drilling plate. The positioning clamping plate has a middle plate that fits the drilling surface and a side that extends from the middle plate to both sides of the part and fits the outer surface of the part. plate, on the drilled plate, there are stops for clamping the positioning clamp from both sides, and the drilled plate is circular and has the same radius as the drilling surface and overlaps; when the middle plate of the positioning clamp and the drill When the orifice plate fits seamlessly and the side plate of the positioning clamp fits seamlessly with the outer surface of the part, the drilling position can be positioned according to the shape of the part. The drilling positioning is convenient and accurate, which can effectively improve the quality and efficiency of sheet metal drilling.

Description

technical field [0001] The invention belongs to the technical field of forming sheet metal parts, and in particular relates to a combined tool for drilling and a use method for drilling an end face with an asymmetric cylinder. Background technique [0002] The drilling technology of sheet metal parts mainly relies on the drilling plate for positioning and hole making. For parts with obvious feature differences, positioning and drilling can be carried out by relying on the shape, but for parts with no obvious features in the shape of the positioning function, the drilling plate cannot be accurately positioned with the part to make holes, and now a combination card for accurate positioning is needed plate to make holes. Contents of the invention [0003] The object of the present invention is to provide a combination tool for drilling and its use method, which can locate the drilling position according to the profile of the part. [0004] A drilling combination tool for dr...
