The connecting portion of described bend pipe and described magnetic force gauge stand is provided with a connector, and described connector one end screws in the screw thread of described magnetic force gauge stand, and the other end welds after inserting described bend pipe; The connecting portion of described bend pipe and described measurement steel loop is provided with a connector, and weld after inserting described bend pipe respectively and measuring steel loop at the two ends of described connector.
Two knees of described bend pipe are welded with a reinforcement respectively.
The lateral surface of described measurement steel loop is parallel with upper and lower two absorption surfaces of described magnetic force gauge stand lateral surface, so need process the lateral surface of measuring steel loop after the utility model integral solder is finished again.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to be provided with a magnetic force gauge stand and a measurement steel loop, in the actual measurement process, can pick up the car the wheel medial surface as measuring basis, the magnetic force gauge stand is adsorbed on the wheel medial surface, directly measure then and measure the distance of steel loop lateral surface to the plane of motor connection gear case with survey instrument, thereby obtain four planes of motor connection gear case and the distance of wheel medial surface indirectly, and after calculating, can more accurately obtain added adjustment pad thickness.2, the utility model is owing to can accurately record the adjustment pad thickness, so can guarantee that its middle plane, gear case assembling back is vertical with axle axis, and then the minimum spacing between assurance gear case medial surface and the gear side, avoid gear case suffered extra-stress when connecting motor, also make the gear case side stressed evenly, prolong the serviceable life of gear case, guarantee traffic safety.The utility model meets design requirement fully, and is simple to operate, and measured value accurately, reliably can be applied to also can be widely used in the assembling process of other model installing locomotive gear cases in the assembling process of DF4 installing locomotive gear cases.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises magnetic force gauge stand 1, and magnetic force gauge stand 1 will have enough suction, and upper and lower two absorption surface A of magnetic force gauge stand 1 lateral surface are even surfaces.Magnetic force gauge stand 1 is connected with one " ∩ " shape bend pipe 2, and bend pipe 2 will have enough toughness and intensity, therefore selects steel pipe for use.For intensity and the rigidity that increases bend pipe 2, be welded with a reinforcement 3 respectively in two knees of bend pipe 2.The other end at bend pipe 2 connects a measurement steel loop 4, and it is for weight reduction that measurement steel loop 4 makes circular one, and the 2nd, measure for convenience.Connecting portion at bend pipe 2 and magnetic force gauge stand 1 is provided with a connector 5, and connector 5 one ends screw in the screw thread of magnetic force gauge stand 1, and the other end inserts bend pipe 2 back welding.Be provided with a connector 6 at bend pipe 2 and the connecting portion of measuring steel loop 4, the two ends of connector 6 are inserted bend pipe 2 respectively and are measured steel loop 4 back welding.Bend pipe 2 is positioned at the vertical end 21 of measuring steel loop 4 one sides, and the vertical end 22 that is positioned at magnetic force gauge stand 1 one sides with bend pipe 2 at grade.
As shown in Figure 2, upper and lower two absorption surface A of magnetic force gauge stand 1 lateral surface and the reference plane of the lateral surface B that measures steel loop 4 for measuring, for upper and lower two the absorption surface A that guarantee magnetic force gauge stand 1 lateral surface and the depth of parallelism of measuring steel loop 4 lateral surface B, in process, should after finishing, the utility model welding again the lateral surface B that measures steel loop 4 be processed.The utility model needs the distance between actual measurement A, B two surfaces, supposes that measured value is a.
As shown in Figure 3, gear case 7 according to the perfect condition installation after, the plane C of gear case 7 relative motors 8 and the distance of wheel 9 medial surface D are b, needing the thickness of the adjustment cushion block that adds between gear case 7 and the motor 8 is e.
Shown in Fig. 4,5, according to above-mentioned two numerical value a, b, just can obtain measuring distance c between the plane C of the lateral surface B of steel loop 4 and gear case 7, i.e. c=b-a (value of c may for just also may be) for negative.
Before actual installation gear case 7, magnetic force gauge stand 1 is adsorbed on the medial surface D of wheel 9, then the lateral surface B that measures steel loop 4 is aligned with the plane E of motor 8 relative gear casees 7, need measure distance between the plane E of the lateral surface B that measures steel loop 4 and motor 8 this moment with measurer, and the actual measured value of supposing this distance is d.
The difference of actual measured value d and above-mentioned resulting numerical value c is exactly the thickness e of this place adjustment cushion block that will add, so the thickness e=d-c of the adjustment cushion block that will add between gear case 7 and the motor 8.
In the process of actual installation gear case, the position on four planes of motor connection gear case all needs to add adjusts cushion block, measures so the utility model successively need be placed on four positions of gear case connection motor respectively.
Shown in Fig. 4,6, be the utility model in the ordinary course of things install and measure position, promptly above-mentioned measuring position.
Shown in Fig. 4,7, in some cases, after the medial surface D that magnetic force gauge stand 1 of the present utility model is adsorbed onto wheel 9 goes up, the plane E that measures steel loop 4 lateral surface B and motor 8 is aligned, can be adsorbed onto magnetic force gauge stand 1 on the plane E of motor 8 this moment, with after measuring the medial surface D of steel loop 4 lateral surface B and aligning with wheel 9, measure the distance of measuring between steel loop 4 lateral surface B and the wheel 9 medial surface D, the method for its calculating pad thickness afterwards is consistent with foregoing method.
The foregoing description only is used to illustrate the utility model; wherein the structure of each parts, the position is set and connected mode all can change to some extent; every improvement of carrying out on the basis of technical solutions of the utility model and equivalents all should not got rid of outside protection domain of the present utility model.
