Description
Technical field
The utility model belongs to the machining tool chuck auxiliary centering holding device field of railway vehicle wheel to mechanism, is specifically related to a kind of new vehicle axle Locating driver frock.
Background technology
The wheel of rail vehicle uses chuck and tail end to be that the circular cone Finial device of d-axis structure holds out against and coaxial positioning the wheel to be processed axle head to mechanism to machining tool usually.As shown in Figure 1, for the hole-bored axle from end to end 6 of center with tubular cavity, in the axle head of hole-bored axle from end to end, be typically provided with location, axle center taper hole 6-1 in the heart, multiple head screwed hole 6-2 by just as angle of circumference be looped around around the taper hole 6-1 of location, axle center.Existing wheel passes through to machining tool the both sides axle head that two groups of coaxially relative chuck mechanisms are clamped in axletree respectively, and insert in location, the axle center taper hole 6-1 at axletree two ends respectively by two conventional circular cone Finial devices, axletree and rotary axis of machine tool are coaxially connected, simultaneously, machine chuck is also inserted in a corresponding head screwed hole 6-2 respectively by multiple alignment pin, does from axle rotary motion in order to axle shaft.The tail end of existing circular cone Finial device is column type d-axis structure, and this column type d-axis structure directly to be inserted in chuck axis top positioning shaft hole in the heart and applied to hold out against thrust vertically by tail springs, guarantees that location, axle center taper hole 6-1 is held out against and coaxially feels relieved.
But, the above-mentioned circular cone Finial device with column type d-axis structure after long-term use, there will be not enough by spring force or owing to occurring between column type d-axis structure and chuck axis top positioning shaft hole in the heart wearing and tearing and gap and the void top phenomenon that causes, this void top phenomenon weakens causing the coaxial pressure of circular cone Finial device to location, axle center taper hole 6-1, and then the mismachining tolerance by causing along himself axial float is overproof to cause axletree to occur in process.Old drives structure mode is that lathe top pawl heads into axle end face, and this makes it only can be applied to half optical axis axletree semi-finished product without retrofit, cannot directly apply to end face and process the smart axle finish turning axletree manufacturing procedure put in place.
Utility model content
In order to solve the existing circular cone Finial device with column type d-axis structure after long-term use, there will be not enough by spring force or owing to occurring between column type d-axis structure and chuck axis top positioning shaft hole in the heart wearing and tearing and gap and the void top phenomenon that causes, this void top phenomenon weakens causing the coaxial pressure of circular cone Finial device to location, axle center taper hole, and then the mismachining tolerance by causing along himself axial float is overproof to cause axletree to occur in process.In addition, on existing machine chuck with multiple head screwed hole one to one alignment pin also easily occur after long-term use wearing and tearing, the degree of depth causing it to insert in head screwed hole is inconsistent, and then causes interference to the homogeneity of its rotary driving force.Moreover; aforementionedly existingly take turns when axle head is held out against to machining tool; also need to install overprotection parallels end cap additional; but end cap easily causes the wearing and tearing to axletree end; this makes it only can be applied to half optical axis axletree semi-finished product without retrofit; cannot directly apply to the technical problem that end face has processed the smart axle finish turning axletree manufacturing procedure put in place, the utility model provides a kind of new vehicle axle Locating driver frock.
