Abstract
The utility model discloses an adjustable reference railway freight car wheel diameter measuring device which includes a fixed measuring scale fixed on a scale body. The fixed measuring scale is provided with a wheel diameter vernier which can slide along the fixed measuring scale. The wheel diameter vernier is provided with a reference vernier which can slide along the wheel diameter vernier. The reference vernier is fixed with a diameter measuring head. The reference vernier is provided with a positioning screw I which can fix the relative positions of the reference vernier and the wheel diameter vernier. The wheel diameter vernier is also provided with the positioning screw II which can fix the relative positions of the wheel diameter vernier and the fixed measuring scale. The adjustable reference railway freight car wheel diameter measuring device is simple in structure and strong in adaptability. Through adjusting the reference vernier, the distance between the diameter measuring head and a positioning reference surface can be adjusted rapidly and conveniently. The adjustable reference railway freight car wheel diameter measuring device is adaptable to a wheel which has a different distance H between an inner side face of a wheel rim and a wheel diameter measurement base line to realize the diameter measurement of the wheels of different types.
Description
Technical field
The utility model relates to the railway freight-car wheel to production testing, belongs to the railway freight-car production technical field.
Background technology
Wheel (as shown in Figure 1) is the critical component of railway freight-car traveling position-bogie, and the stability and the security that move for lorry have key effect.Therefore, in the assembling of bogie, wheel diameter, the same wheel there are strict regulation to two wheel diameter differences, need to carry out strict detection, apolegamy and inspection.
At present, in the production of railway goods train bogie, wheel can carry out the detection of wheel parameter fast and accurately to the parameter auto-testing machine.But railway freight-car wheel diameter dip stick still has irreplaceable effect because of its conveniently moving, not limited by the place.Traditional railway freight-car wheel footpath dip stick is a positioning reference with the rim for automobile wheel medial surface, and the diameter gauge head is fixed on the vernier of wheel footpath by wheel design size H, measures taking turns right diameter.
Along with the increase of lorry product bogie product variety, the pattern of wheel constantly increases, and the distance that wheel rim medial surface and wheel diameter are measured baseline also no longer is a fixed value.The nonadjustable wheel diameter dip stick of traditional diameter gauge head and positioning reference relative distance can not satisfy the detection requirement of wheel diameter, its shortcoming is: when the distance H of wheel rim medial surface and wheel diameter measurement baseline changes, must design and produce new wheel diameter dip stick, cause long, equipment input height of production cycle.
The utility model content
At the problem that existing railway freight-car wheel footpath dip stick exists, the utility model provide a kind of simple in structure, benchmark can be adjusted, adaptable adjustable reference railway freight-car wheel calipers.
For achieving the above object, the utility model adopts following technical scheme:
A kind of adjustable reference railway freight-car wheel calipers, it comprises blade, and the blade two ends all are fixed with the fixing chi of surveying, and each is fixing surveys and is equipped with on chi and can surveys the wheel footpath vernier that chi slides along fixing, and wheel footpath vernier is provided with the benchmark vernier that can slide along wheel footpath vernier; Described benchmark vernier is provided with the diameter gauge head.
Described benchmark vernier is provided with the dog screw that the relative position of benchmark vernier and wheel footpath vernier is fixed.
Beneficial effect: compared with prior art the utlity model has following advantage:
1. the utility model is adjustable structure by increasing the benchmark vernier with wheel footpath vernier and the fixing architecture advances of diameter gauge head, can conveniently adjust the distance of diameter gauge head and positioning reference.
2. the utility model has solved the problem that conventional wheel diameter measurement chi can not adapt to the different types wheel.
3. design feature of the present utility model reduces the cost of wheel detection, apolegamy, inspection in the railway freight-car production.
Description of drawings
Fig. 1 is the wheel synoptic diagram;
Fig. 2 is the structural representation of the utility model wheel calipers;
Fig. 3 is the vertical view of Fig. 2;
Wherein: 1, blade, 2, the fixing chi of surveying, 3, wheel footpath vernier, 4, the benchmark vernier, 5, the diameter gauge head, 6, the dog screw II, 7 dog screw I, the 8 fixing chi reference fields of surveying, 9 wheel rim medial surfaces, 10 wheel diameters are measured baseline.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, wheel rim medial surface 9 is a fixed value with the distance that wheel diameter is measured baseline 10, its shortcoming is: when the distance H of wheel rim medial surface 9 and wheel diameter measurement baseline 10 changes, must design and produce new wheel diameter dip stick, cause long, equipment input height of production cycle.As shown in Figures 2 and 3, the utility model adopts two adjustable reference wheel calipers of symmetry to measure wheel diameter, and they comprise fixing chi 2, two wheel footpath verniers 3, two benchmark verniers 4, two diameter gauge heads 5 and four dog screws 6 surveyed of 1 blade 1, two.
The fixing chi 2 of surveying is installed on the blade 1, and fixing with blade 1; Wheel footpath vernier 3 is installed in fixing the survey on the chi 2, and can slide fixing the survey on the chi, realize the detection of different wheel diameter, on the vernier 3 of wheel footpath dog screw II 6 is installed, can fix wheel footpath vernier 3 and the fixing relative position of surveying chi 2, be used to detect the location, back and read wheel footpath measured value; Benchmark vernier 4 is installed on the vernier 3 of wheel footpath, and can slide along wheel footpath vernier 3, realize diameter gauge head 5 and fixing adjustment of surveying chi reference field 8 distances, dog screw I 7 is installed on the benchmark vernier, can fix the relative position of benchmark vernier 4 and wheel footpath vernier 3; Diameter gauge head 5 is fixed on the benchmark vernier 4.
After adopting above-mentioned technology, this wheel calipers is by the position adjustments of benchmark vernier 4, according to corresponding wheel diameters, diameter gauge head 5 and fixing chi reference field 8 distances of surveying are adjusted, located, solve the traditional railway truck wheel footpath chi problem that fixing wheel diameter detects of can only adjusting the distance.
The utility model is simple in structure, adaptability is strong.By adjusting benchmark vernier 4, can conveniently adjust diameter gauge head 5 and the fixing distance of surveying between the chi reference field 8, adapt to wheel rim medial surface 9 and measure the different wheel of baseline 10 distances with wheel diameter, realize that the diameter of different types wheel detects.
