Background technology
Train wheel Rolling Production needs through operations such as preformed, rolling, press-bendings, in preforming operation, due to the reason such as mold center, steel billet male and female face, aligning arm be asynchronous, cause steel billet circumferencial direction maldistribution, train wheel circular rim rolling is eccentric, wheel rolling bias is the difficult problem that wheel rolling is produced always, the eccentric class waste product of wheel rolling accounts for the first place of wheel waste product always, therefore need to determine that the eccentric situation of train wheel circular rim is so that follow-up finish rolling is made adjustment to bias, meets the index request of wheel production technology.Not yet openly be applied at present the determinator of train wheel bias, just at train wheel after 90MN compacting, execute-in-place workman detects by an unaided eye the full state in wheel rim, rim face, judges eccentric direction by qualitatively analyze.Problems existing is that execute-in-place workman detects by an unaided eye, one is cannot by analyzing quantitatively, judging train wheel circular rim rolling eccentric direction, two is when light is poor, wheel eccentricities situation is easily done to the judgement made mistake, cause follow-up finish rolling to adjust inaccurate, wheel rejection rate is high, and rate of melting down is high, energy resource consumption is large, increases production cost.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of train wheel degree of eccentricity analyzer, analyzing quantitatively, judging train wheel circular rim rolling eccentric direction, reduce wheel rejection rate and melt down rate, reduce energy resource consumption, save production cost.
Train wheel degree of eccentricity analyzer, be characterized in that this analyzer is connected and composed by main scale, vernier and sliding sleeve, described vernier is provided with long measure scale, is vertically located at one end of sliding sleeve, is fixed by securing member; Described main scale is provided with long measure scale, and sliding sleeve slides on main scale, is fixed by securing member, exposes the long measure scale of main scale.
The present invention improves further, and described main scale positioning end establishes main scale gauge head, and its width is slightly wider than chi body width, and main scale gauge head divides into shell face gear foot, and main scale counting end establishes a millimeter scale.
The present invention improves further, and described vernier connects and composes by vernier gauge head is vertical with chi body, and vernier gauge head lower end establishes rim face to keep off foot, and chi body establishes a millimeter scale, and under zero graduation and vernier gauge head, flat limit together in a straight line.
The present invention improves further, described sliding sleeve is shorter in length than main scale length, screw is established in sliding sleeve and side, vernier junction, sliding sleeve and main scale are by screw stop, and opposite side establishes sleeve, establish rectangular through-hole corresponding with vernier chi body in sleeve, rectangular through-hole center line and sliding sleeve center line orthogonal, establish screw outside sleeve, vernier chi body is sliding to be contained in rectangular through-hole, is fixed by screw.
The present invention improves further, and described shell face gear is sufficient, rim face keeps off sufficient planform, size is consistent, and gear foot is inclined-plane or arc surface near wheel face, does not form interference to the measurement of wheel.
This positioning rule is applicable to the wheel of shell face higher than rim face, during use, first be the relative height size in shell face and rim face by vernier stylus adjustment, by screw fastening on sliding sleeve, then move main scale, until main scale gauge head is stuck on shell face, by screw fastening main scale, then by adjustment vernier gauge head until be stuck in Wang Mianshang, read main scale and numerical value corresponding to vernier, carry out multi-angle location according to upper step, find eccentric direction.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; This positioning rule adopts main scale to match with vernier, shell face gear foot on both, rim face gear foot position, can by analyzing quantitatively, judging train wheel circular rim rolling eccentric direction, for follow-up finish rolling provides accurate data, carry out finish rolling rolling adjustment in time, correct eccentric, reduce the rejection rate that wheel causes because of eccentric, reduce wheel waste product simultaneously and melt down rate, energy resource consumption reduces, and effectively saves production cost.
