Compared with prior art, the utility model has changed traditional sorting mode, adopts a plurality of standard door openings of arithmetic series arrangement of pressing as examination criteria.Tested spring is by the highest standard door opening standard door opening by reducing successively successively, when tested spring when the free height state can not be by certain standard door opening, the height dimension of spring is just between this standard door opening and the previous standard door opening that can pass through.Adopt measuring tool of the present utility model to carry out sorting, simple to operate, can raise the efficiency; Axially not stressing of spring can reduce personal error, improves sharpness of separation; Do not need often to change vernier height gauge, can reduce the sorting cost.After the utility model put into operation, the work efficiency of spring sorting was multiplied, and testing staff's labour intensity also alleviates greatly.According to measuring and calculating, annual artificial expenditure of saving and testing cost are more than about ten thousand yuan.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-base plate, 2-standard door opening, 3-door pillar, 4-crossbeam, 5-positioning table, 6-double-screw bolt, 7-hole, 8-gland nut, the tested spring of 9-.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.The utility model as shown in Figure 1.A kind of measuring tool by free height sorting railway goods train bogie spring comprises base plate 1, and base plate 1 is provided with the standard door opening 2 that one group of height is arranged by arithmetic series.Described standard door opening 2 comprises the crossbeam 4 that two door pillars 3 and door pillar support.Described door pillar 3 is provided with positioning table 5, and positioning table 5 is provided with double-screw bolt 6.Described crossbeam 4 is provided with hole 7, and hole 7 is through on the double-screw bolt 6, and double-screw bolt 6 is provided with gland nut 8.
A concrete method for separating of the present utility model is as follows.
Need be that 252mm spring 9 carries out sorting to height dimension, spring 9 be 3mm adding the maximum upper deviation that allows man-hour, and spring 9 is 2mm adding the minimum lower deviation that allows man-hour.That is to say that the spring that processes all is qualified between 250～255mm.But the spring that is used for same vehicle requires error to be not more than 2mm.As required, be provided with 6 standard door openings 2, the height of each door opening differs 1mm, is followed successively by 255mm, 254mm, 253mm, 252mm, 251mm and 250mm.Following 255～254mm, 254～253mm, 253～252mm, 252～251mm, five altitude ranges of 251～250mm between 6 standard door openings, have been formed.Tested spring 9 shown in the arrow among Fig. 1, from high to low successively by standard door opening 2, is taken out can not be by a certain standard door opening the time, this moment spring height can not by with the altitude range of the standard door opening that passes through at last in.Height as intransitable standard door opening is 252mm, as last height by the standard door opening is 253mm, then the spring height is 252～253mm, so just can elect tested spring 9 as 5 groups by the free height branch, every group height error is not more than 1 mm, according to producing and client's needs, the spring free height of any two adjacent set differs and is no more than 2mm.Can between any two adjacent regions, match, so both satisfy the apolegamy requirement, improve selecting efficiency again.If when sorting, it is the standard door opening of 255mm highly that tested spring 9 can not pass through, maybe can be by highly all thinking substandard product for the standard door opening of 250mm.
