Linear measurement arrangement method for stainless steel vehicle roof cap-shaped curved beams

Abstract

The invention relates to a linear measurement arrangement method for stainless steel vehicle roof cap-shaped curved beams, which is characterized by comprising the following steps of: firstly, placing one stainless steel vehicle roof cap-shaped curved beam with a center hole in a groove body with a center positioning pin, arranging one measuring block of which the center of the bottom is provided with a pinhole on the upper surface of the stainless steel vehicle roof cap-shaped curved beam, enabling the pinhole at the bottom of the measuring block to be coaxially matched with the center positioning pin of the groove body for leading the center of the stainless steel vehicle roof cap-shaped curved beam, which is positioned at the bottom of a groove and cannot be measured, to the top surface and determining the center positioning of the stainless steel vehicle roof cap-shaped curved beam; and then, for a plurality of groups of stainless steel vehicle roof cap-shaped curved beams of a vehicle, aligning center mark points on the upper surfaces of a plurality of measuring blocks, connecting the center mark points into a line and carrying out interval size arrangement and measurement by using a straightedge rule. According to the invention, one measuring block of which the center of the bottom is provided with the pinhole is arranged on the upper surface of one stainless steel vehicle roof cap-shaped curved beam, the pinhole at the bottom of the measuring block is coaxially matched with the center positioning pin of the groove body to lead the center at the bottom of the groove, which cannot be measured, to the top surface, the center mark points of a plurality of measuring blocks are aligned and connected into one line, and the interval size arrangement and measurement are implemented by the center marks on the top surfaces of the measuring blocks through using the straightedge rule.

Description

technical field [0001] The invention belongs to the technical field of rail passenger car manufacturing, and relates to the arrangement and measurement of the forming process of a novel stainless steel roof hat-shaped curved beam. Background technique [0002] The roof of the new stainless steel rail car model adopts a hat-shaped curved beam in section. For a roof composed of multiple sets of stainless steel roof hat-shaped curved beams, the spacing and central symmetry of the arrangement must be guaranteed. Since the central positioning pin of the groove supporting body supporting the hat-shaped curved beam is lower than the top surface of the roof hat-shaped curved beam, it is impossible to arrange and measure the interval size of the hat-shaped curved beam of the new model with a linear ruler. Contents of the invention [0003] The purpose of the present invention is to provide a method for measuring and arranging the hat-shaped curved beams of stainless steel car roofs...
