Embodiment Construction

[0019] The detailed steps of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] A method for rapidly manufacturing high-strength bolt holes, comprising the steps of:

[0021] Step 1. According to the attached figure 1 The dimensions of the bolt hole groups shown in the legend for the bolt hole template shown, determine the diagonal ab of the rectangle, Take a piece of galvanized steel plate with a corresponding size of δ=1.0mm, use drawing rules to draw a semicircular arc on the galvanized steel plate with point o as the center, and the radius length is ab / 2, randomly pick a point a on the arc, connect ao and The arcs intersect to get point b, draw the line aob, and determine the diagonal (as shown in the attached figure 2 shown).

[0022] Step 2. Take a and b as the center of the circle and 100mm as the radius (the radius of 100mm is the distance between the two rows of bolt holes in the legend of the bolt hole t...

Abstract

The invention discloses a method for rapidly manufacturing high-strength bolt holes. The method comprises the steps that 1, according to the dimensions of a bolt hole set, the length of a diagonal line of a rectangle formed by two rows of bolt hole sets is determined, a thin zinc-plated steel plate is selected, and the rectangle diagonal line is drawn; 2, a standard rectangular line frame is determined; 3, according to the positions of all the bolt holes, mark points are drilled; 4, after center points of the bolt holes are determined, blanking is carried out on the zinc-plated steel plate according to the dimension in a bolt hole template legend, one steel plate with the equal size and the thickness delta being 12-20 mm is taken and completely covered with a zinc-plated template, small holes are led out, then the bolt holes are drilled, and a bolt hole template is manufactured; and 5, auxiliary bolt hole machining is carried out through the bolt hole template manufactured in the step 4. Bolt hole distance control precision is high, the repeated service life is prolonged, it is ensured that machining scrap iron is effectively removed, and fixing is convenient.

Description

technical field [0001] The invention relates to a method for manufacturing bolt holes, in particular to a method for rapidly manufacturing high-strength bolt holes, and belongs to the technical field of mechanical design. Background technique [0002] High-strength bolts are used more and more widely in building construction. The weight of high-strength bolts in steel structure construction is increasing, and poor control of the allowable deviation of high-strength bolt holes will directly affect the construction quality, construction schedule, and construction cost of steel structures. Due to the deviation of the bolt holes during the installation of high-strength bolts, the bolts must not be reamed by flame gas cutting during installation. No matter what method is used, it is very troublesome. Therefore, it is very important to control the effective deviation of the bolt holes in the steel structure production. The specification stipulates that the allowable deviation of ...
