Abstract

The invention relates to an accurate positioning method for fixing nuts of an alloy steel trapezoid protection plate. The accurate positioning method comprises the specific steps that 1, a mold for accurately positioning the buried-cast nuts is made of a steel plate; 2, the nuts are point-connected with the trapezoid plate in point welding holes; and 3, the mold is taken off, the peripheries of the nuts are arranged well, and in this way, accurate positioning is achieved.

Description

technical field [0001] The invention relates to the field of nut positioning, in particular to a precise positioning method for a fixing nut of an alloy steel trapezoidal guard plate. Background technique [0002] The high chromium cast iron trapezoidal guard plate generally has four fixed support points. The conventional method is to bury four nuts on the outside of the trapezoidal plate, and then fix the nuts with bolts through the reserved holes on the cover box to achieve the purpose of fixing the trapezoidal plate. Due to the error of the shape during casting and the displacement generated when the molten iron solidifies and shrinks, it is difficult to accurately locate these embedded casting nuts, which makes installation difficult. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a method for precisely positioning the fixing nut of the alloy steel trapezoidal guard plate. [0004] T...
