Embodiment
The nouns of locality such as " upper and lower, tail, top, the ends " that relate in the utility model all with the utility model high manganese steel frog groove width dedicated test measurer under normal operating condition towards consistent.
As shown in Figures 1 to 3, the utility model high manganese steel frog groove width dedicated test measurer, is applicable to tread face 1:20 angle, and working edge datum line is the domestic high manganese steel frog of 16mm and the detection of section port high manganese steel frog groove width, and it comprises main scale 1 and chi frame 2.
This main scale 1 Integral rectangular plate body structure, its thickness 6mm, material is 65 steel (high-duty cast carbon structural steels) and two sides are along its length equipped with scale; Wherein, positioning caliper 11 is provided with on the downside of this main scale 1 one end; This positioning caliper 11 lower surface is the first detection faces 111, contacts when this first detection faces 111 is the ramp structure of angle 1:20 and measures with the end face of one of them workpiece railway frog; This positioning caliper 11 tail down has extended to form positioning wedged block 12, and this side, positioning wedged block 12 bottom is the second detection faces 121; When this second detection faces 121 is edge structure and measures and the sidewall contact of workpiece railway frog.
This chi frame 2 coupling is installed on main scale 1, and it is bearing steel (GCr15) and comprises scale 21, screens chi 22 and lock-screw 23.This scale 21 is overall rectangular, its coupling to be arranged on main scale 1 and with main scale 1 sliding connection; This scale 21 1 side offers draw-in groove 211, this draw-in groove 211 is rectangular channel body structure and matches with main scale 1 width, the top of this draw-in groove 211 both sides cell wall is arranged with limited block 212, and this scale 21 coupling is arranged in after on this main scale 1 spacing by limited block 212.
This screens chi 22 is formed by stretching out on the downside of scale 21 one end, and its bottom is that the 3rd detection faces the 221, three detection faces 221 is when being also edge structure and measuring and the sidewall contact of workpiece railway frog back to positioning caliper 11 side.
The detachable upside being installed on this scale 21 of this lock-screw 23, can make this chi frame 2 lock onto on this main scale 1 by this lock-screw 23; Wherein, when when measuring workpieces 3, unclamp lock-screw 23, after having measured workpiece 3 size, then screw lock-screw 23 and make scale 21 be locked in this main scale 1, now measurer is taken off from workpiece 3, read size scale.
Wherein, the hardness >=58HRC of this first detection faces 111, second detection faces 121 and the 3rd detection faces 221, measurement range is 24mm ~ 100mm; Wherein, when measuring workpieces railway frog groove width, contacted with the top end face of workpiece railway frog by the first detection faces 111, being contacted with adjacent pair of workpieces railway frog respectively by the second detection faces 121, the 3rd detection faces 221 is relative sidewall, can realize high manganese steel frog and quantitatively detect.
Principle of work of the present utility model:
Measurer is placed in workpiece 3 end face, accurately locate by realizing measurer main scale 1 on the left of the first detection faces 111 of positioning caliper 11 lower end and the second detection faces 121 of positioning caliper 11 afterbody, then slip chi frame 2, detects railway frog groove width.
Below in conjunction with Fig. 2,3, optimal way of the present utility model is further illustrated;
