Embodiment Construction
[0019] The specific implementation of the measurement method will be further described below in conjunction with the accompanying drawings, taking the concentricity measurement of the flange of the burner nozzle on the side wall of the gasifier as an example.
[0020] The tools for measuring the concentricity of the butt joint flange of small-diameter container equipment include: ruler or tape 5, platform 3, contour block 2, pink wire or steel wire 4, and square 8.
[0021] When measuring, place the measuring cylinder 1 on the platform 3, then place a contour block 2 on the inner wall of the symmetrical connecting flange 6 to be measured, tighten the powder line 4 on the pad 2, and measure the inner wall of the symmetrical connecting flange 6 to the powder. The distance h4 between the lines 4 is measured at the positions of the four centerlines in sequence. Among them, the center line is the center line divided by the four equal parts of the outer circumference of the equipmen...

The invention discloses a method for measuring the concentricity of butt joint flanges of small-diameter container equipment, which belongs to the field of container manufacturing and processing, and overcomes the defect of excessive measurement errors in the prior art. Measuring tools include: 1 tape measure or steel ruler, 1 platform, 2 contour blocks, 1 square, 2 powder wires or steel wires; when measuring, place the measuring cylinder 1 on the platform 3, and then measure the required Place the contour block 2 on the inner wall of the measured symmetrical connecting flange 6, tighten the pink line 4 on the block 2, measure the distance h4 between the inner wall of the symmetrical connecting flange 6 and the pink line 4, and measure at the four center line positions in turn . Carrying out the above-mentioned program measurement on each pair of symmetrical flanges 6 or connecting pipes in turn can check whether the two symmetrical flanges or connecting pipes are concentric. The method can meet the measurement of the concentricity of the flanges of the symmetrical two connecting pipes of the small-diameter container equipment, and reduce the assembly error; the measuring tools are commonly used, and no additional investment is required; the operation is simple, and the measurement is relatively accurate.
Description
Technical field [0001] The invention belongs to the field of container manufacturing and processing in the machinery industry. Background technique [0002] In the machinery industry, during the manufacturing process of container equipment, it is often necessary to install some connecting flanges symmetrically. Sometimes, relatively high special requirements are put forward for the control of the concentricity, verticality and concentricity of the connecting flanges. Regarding the measurement of the concentricity of the butt joint flange of small-diameter container equipment, the existing technology only uses a two-point drawing powder line to measure the positioning size, overhang height, and mid-span size of a single connecting flange. This method has a large cumulative error in measurement and concentricity The degree is difficult to control and the production efficiency is low.
