Problems solved by technology

Although the drilling accuracy can be guaranteed, since the device can only drill the upper or lower flange of the H-shaped steel, when it is necessary to drill another flange, it needs to be turned over and repeated, and the upp

Abstract

A large-sized H-shaped steel drilling die comprises an upper positioning template, a lower positioning template, a support plate, a positioning assembly and adjusting bolts, wherein a plurality of positioning holes are formed in the upper positioning template and the lower positioning template; the positioning holes are the same as holes to be processed in H-shaped steel in size, quantity and position; the support plate comprises a left support plate and a right support plate; the upper positioning template is fixedly connected with the lower positioning template through the left support plate and the right support plate to form a template body; the positioning assembly is arranged at one end of the template body; the adjusting bolts are uniformly distributed on the upper positioning template, the lower positioning template and the support plate. According to the large-sized H-shaped steel drilling die, the upper positioning template, the lower positioning template, the support plate and the positioning assembly are arranged, so that holes in an upper flange plate and a lower flange plate of the H-shaped steel can be subjected to drilling at the same time; therefore, the requirement of holes in the upper flange plate and the lower flange plate for coaxiality is met, and the position precision of all the holes in the flange plates is guaranteed.

Description

technical field [0001] The invention relates to a drilling mold, in particular to a large H-shaped steel drilling mold. Background technique [0002] In the process of drilling large-scale H-shaped steel, according to actual needs, holes are often drilled on the upper and lower flanges of H-shaped steel, and the coaxiality of the holes at the upper and lower corresponding positions must meet certain accuracy requirements. Due to the weight and size of the large H-beam itself, the accuracy of the drilling position, especially the coaxiality of the upper and lower holes, is difficult to guarantee. And the existing method mainly contains two kinds: 1), the upper and lower planes are respectively marked and drilled; 2), the center line is drawn and the drilling template is drilled. These two methods are aimed at the regular H-shaped steel, and when the end face of the H-shaped steel is inclined, the positioning reference cannot be controlled, so there is a large error in the me...
