Step 1: sleeper beam measurement apparatus in assembling,
Step 2: simultaneously contact point at least two is machined out so that the flatness error≤0.01mm of upper plane,
Step 3: simultaneously contact point under at least four is machined out so that the upper depth of parallelism //≤0.05mm between plane and lower plane.
Owing to contact point is to be machined out after middle sleeper beam measurement apparatus assembles under contact point and at least four in this at least two simultaneously, use the depth of parallelism //≤0.05mm that this mach mode is easier to ensure that between plane and lower plane.
When the middle sleeper beam measurement apparatus that the present invention provides is the middle sleeper beam measurement apparatus that embodiment two provides, after the top edge of biside plate 12 and 13 is machined out, include quenching and the step of tempering the most successively;Quenching and the step of tempering is included the most successively after the bottom surface of four cushion blocks is machined out.Wherein, quenching ensure that anti-wear performance, tempering have the effect eliminating internal stress.
The method that sleeper beam in rail vehicle is measured by the middle sleeper beam measurement apparatus that the application present invention provides comprises the following steps:
See accompanying drawing 2, step 1: the middle sleeper beam measurement apparatus that the present invention provides be positioned over and be placed between the left web 5 of middle sleeper beam and right web 4 in the center cavity formed,
One horizon rule 7 is positioned in middle sleeper beam measurement apparatus, the upper contact point of horizon rule 7 contact, the lower contact point of central beam cover plate 3 end face contact of middle sleeper beam,
Measure 1. " vertical range d between lower cover 1 and horizon rule 7 respectively1" and the depth of parallelism //1", 2. " vertical range d between side bearing base plate 6 and horizon rule 72" and the depth of parallelism //2", 3. " vertical range d between lamina tecti 2 and horizon rule 73" and the depth of parallelism //3",
In order, the distance between contact point and lower contact point is d ', then, d1"-d '=d1, d2"-d '=d2, d3"-d '=d3, //1"=//1, //2"=//2, //3"=//3。
The depth of parallelism //≤0.05mm between upper plane and the lower plane of the middle sleeper beam measurement apparatus provided due to the present invention above, horizon rule contacts with upper contact point, central beam cover plate 3 end face of middle sleeper beam contacts with lower contact point, during application, the depth of parallelism between horizon rule 7 and middle sleeper beam central cover plate 3 end face also≤0.05mm, therefore, 1. " vertical range d between lower cover 1 and horizon rule 7 obtained is measured1" and the depth of parallelism //1", 2. " vertical range d between side bearing base plate 6 and horizon rule 72" and the depth of parallelism //2", 3. " vertical range d between lamina tecti 2 and horizon rule 73" and the depth of parallelism //3" the most accurate, and now, if the upper distance between contact point and lower contact point of order is d ', then, d1"-d '=d1, d2"-d '=d2, d3"-d '=d3, //1"=//1, //2"=//2, //3"=//3The most accurate.
In the present embodiment, d '=350mm, if standard is d1=81 ± 3.2mm, //1≤ 3.2mm, d2=25.50 +3Mm, //2≤ 1.6mm, d3=411 ± 3.2mm, //3≤1.6mm.After the middle sleeper beam measurement apparatus that the application present invention provides is in rail vehicle, the above-mentioned size of sleeper beam measures, if meeting above-mentioned standard, then as finished product, if not meeting above-mentioned standard, then need to do over again.
Additionally, the middle sleeper beam measurement apparatus that the present invention provides can also be applied to the measurement of the mechanism similar with sleeper beam in this rail vehicle, thus ensure measurement accuracy.
Described detailed description of the invention; the purpose of the present invention, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only the detailed description of the invention of the present invention; it is not limited to the present invention; all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, should be included within the scope of the present invention.
