Abstract
The utility model discloses a kind of locomotive under repairing driven gear and press-fit support measurement frock, cylinder frock top is provided with brace table, middle part is provided with measuring basis platform, cylinder frock midcircumferential plane is provided with two symmetrical measurement peep holes, and the wheel hub bottom surface of driven gear is pressed on the brace table of cylinder frock; Insert in the endoporus of driven gear under the axletree deadweight state matched with driven gear, the axletree standard station of axletree is intrusion to the distance of the measuring basis platform of cylinder frock.The utility model has the advantage of easy to use, dexterous; What realize driven gear and axletree press-fits that precision is high, reliable in quality; Adapt to the productive prospecting that locomotive under repairing kind is changeable.Press-fit supporting by development locomotive under repairing driven gear and measure frock, can more convenient and quicker, effectively carry out press-fiting of locomotive under repairing driven gear and axletree, and the changeable maintenance of adapted breed is produced, the saving cost of overhaul.
Description
Technical field
The utility model relates to a kind of measurement frock, particularly relates to a kind of measurement frock press-fiting support for locomotive under repairing driven gear, belongs to locomotive field.
Background technology
Driven gear is the critical component of driving device for locomotives, it and axletree press-fit the security of operation of quality concerning locomotive.When locomotive is newly made, a driven gear pressing machine from Germany's a whole set of import, the active length of pressing machine is fixed, cannot meet dissimilar driven gear and press-fit, more be not suitable with the productive prospecting of locomotive under repairing multi-varieties and small-batch.
Existing driven gear pressing machine complex structure, manufacturing cost is higher, adapts to workpiece kind single, cannot meet dissimilar driven gear and press-fit, more be not suitable with the productive prospecting of locomotive under repairing multi-varieties and small-batch.
Summary of the invention
The utility model pin is single for solving adaptation workpiece kind, dissimilar driven gear cannot be met press-fit, more be not suitable with the technical problem of the productive prospecting of locomotive under repairing multi-varieties and small-batch, propose a kind of locomotive under repairing driven gear and press-fit support measurement frock, improve production efficiency.
This locomotive under repairing driven gear press-fits to support measures frock, cylinder frock top is provided with brace table, middle part is provided with measuring basis platform, and cylinder frock midcircumferential plane is provided with two symmetrical measurement peep holes, and the wheel hub bottom surface of driven gear is pressed on the brace table of cylinder frock; Insert in the endoporus of driven gear under the axletree deadweight state matched with driven gear, the axletree standard station of axletree is intrusion to the distance of the measuring basis platform of cylinder frock.
The lower outer diameter of described cylinder frock is greater than the top external diameter of cylinder frock.
The utility model has the advantage of easy to use, dexterous; What realize driven gear and axletree press-fits that precision is high, reliable in quality; Adapt to the productive prospecting that locomotive under repairing kind is changeable.Press-fit supporting by development locomotive under repairing driven gear and measure frock, can more convenient and quicker, effectively carry out press-fiting of locomotive under repairing driven gear and axletree, and the changeable maintenance of adapted breed is produced, the saving cost of overhaul.
Accompanying drawing explanation
Fig. 1 is that locomotive under repairing driven gear press-fits the structural representation supporting and measure frock.
Fig. 2 is the structural representation that before axletree press-in, intrusion is measured.
Fig. 3 is the structural representation after axletree press-in.
Reference numeral is as follows: 1-cylinder frock, 2-brace table, 3-measuring basis platform, 4-peep hole, 5-axletree, 6-driven gear, 7-axletree standard station, F-pressure assembling force, h-intrusion.
Detailed description of the invention
Press-fit support measurement frock below in conjunction with accompanying drawing to locomotive under repairing driven gear to be further described.
This locomotive under repairing driven gear press-fits to support measures frock, comprise driven gear 6 and axletree 5, cylinder frock 1 top is provided with brace table 2, middle part is provided with measuring basis platform 3, cylinder frock 1 midcircumferential plane is provided with two symmetrical measurement peep holes 4, and the wheel hub bottom surface of driven gear 6 is pressed on the brace table 2 of cylinder frock 1; Insert in the endoporus of driven gear 6 under the axletree 5 deadweight state matched with driven gear 6, the axletree standard station 7 of axletree 5 is intrusion h to the distance of the measuring basis platform 3 of cylinder frock 1.The lower outer diameter of described cylinder frock 1 is greater than the top external diameter of cylinder frock 1.
This locomotive under repairing driven gear press-fits to support measures frock, and when cylinder frock 1 works, this frock needs to be placed on the work top of forcing press, considers the stability of frock, and the base diameter of cylinder frock 1 is greater than the diameter on cylinder frock 1 top.The top of cylinder frock 1 is provided with supporting station 2, for locating bottom driven gear 6 wheel hub, bears pressure assembling force when working simultaneously.Measuring basis platform 3, two effect is provided with: one is press-fit pre-test intrusion h (figure bis-) in the middle of cylinder frock 1; Two is that after axletree press-in, axletree standard station 7 is closely connected with measuring basis platform 3, does not enter (figure tri-), as the foundation whether Work inspection device is qualified with the inspection of 0.02mm clearance gauge.The centre of cylinder frock 1 is circumferentially also being provided with two symmetrical peep holes 4, for measuring intrusion and observation press-fits state.
This frock is load parts, and adopt structural alloy steel to make, blank forging, overall modifier treatment, according to the distance on different axle diameters Choice and process measuring basis platform 3 both sides, to adapt to the changeable productive prospecting of locomotive under repairing kind; Centre position symmetrical machining two peep holes 4 of cylinder frock 1, finally do selective hardening process, hardness number HRC45-50 by the supporting station 2 on top and the measuring basis platform 3 at middle part.
Use procedure: first locomotive under repairing driven gear is press-fited supporting measurement frock and be placed on press bench, fixing behind adjustment Center of Pressure, again driven gear 6 is placed in this frock, axletree 5 of slinging penetrates driven gear 6 endoporus, intrusion h (figure bis-) is measured under deadweight state, regulate the active length of forcing press, active length is made to equal intrusion h, the brace table (2) calculating design to measuring basis platform (3) distance and intrusion h's and contrast with the designing requirement of drawing, whether in error allowed band, back axle standard station 7 is pressed into closely connected with this frock measuring basis platform 3 if met the requirements, and do not enter (figure tri-) with the inspection of 0.02mm clearance gauge, as the foundation whether Work inspection device is qualified.
