Abstract

The invention provides a drilling mould for machining a bottom corner of an oil tank. The drilling mould is simple in structure, the hole pitch can be accurate in machining, physical strength and time of operators are greatly saved, and production efficiency is improved. The drilling mould comprises a base and is characterized in that support columns are fixed to four corners of the base, positioning columns are arranged on the inner sides of the support columns on the base through first bolts, positioning pins are fixed onto the positioning columns, top plates are fixed to two ends of the base, nuts are welded on the inner sides of the top plates, second bolts penetrate the top plates and are screwed and fastened on the nuts, a drilling template is positioned by the positioning pins, guide holes are formed in the drilling template positioned at the centers of the corresponding support columns, and drilling sleeves are mounted on the guide holes.

Description

technical field [0001] The invention relates to the technical field of production equipment processing tooling, in particular to a drilling die for processing the bottom corner of an oil tank. Background technique [0002] Generally, for the machining of the bottom corner of the oil tank of the machine tool, the machining accuracy is relatively high, and the machining hole distance must be within the position tolerance. 0.5mm, and the existing drilling method is to manually drill holes according to the scribe line on the drilling machine after scribe line, which not only increases the labor intensity, but also the accuracy of manual drilling is not high. Contents of the invention [0003] In view of the above problems, the present invention provides a drilling die for processing the bottom corner of the fuel tank, which has a simple structure, can ensure accurate processing of the hole distance, greatly saves the physical strength and time of the operator, and improv...
