Technical field
The utility model relates to the maching of Al wheel apparatus field more particularly to a kind of improved the maching of Al wheel Positioning core axle.
Background technique
Currently, aluminium alloy wheel hub in milling machine processing is positioned using mandrel, hub centre hole is mounted on mandrel and is carried out Positioning process, existing positioning method is as shown in Fig. 1 in Figure of description, by fixed central spindle 01, fixing bolt 02 and mandrel Pedestal 03 forms, and in positioning, since the size of fixed central spindle 01 is fixed, therefore is only applicable to machining center hole ruler using the mandrel Very little identical wheel hub, since wheel hub has many different central hole sizes, scene needs to make the mandrel of many specifications, On the one hand increase production cost, on the other hand also increase field management difficulty, when replacing wheel-type, central hole size is different, then needs Mandrel is replaced, mandrel is found and dismounting mandrel delays many times, reduce production efficiency;In addition, fixed central spindle 01 uses Abrasion is had after a period of time, fixed central spindle 01 and centre bore cooperation have gap, and when gap is excessive, meeting occurs for processing dimension Occur to deviate and requirement on machining accuracy is not achieved, the serious wheel hub that even results in is scrapped, we have devised a kind of improvement thus The maching of Al wheel positioning core axle solve problem above.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of improved aluminium proposed closes Golden wheel hub processes positioning core axle.
To achieve the goals above, the utility model uses following technical solution:
A kind of improved the maching of Al wheel positioning core axle, including mandrel pedestal, the upside of the mandrel pedestal are equipped with Ringfeder mandrel, ringfeder mandrel are equipped with gag lever post, the center of gag lever post, ringfeder mandrel and mandrel pedestal far from the side of mandrel pedestal It is equipped with coaxial through-hole, and is equipped with fixing bolt in through-hole, mandrel pedestal is equipped with hydraulic cylinder far from the side of ringfeder mandrel, And the inside of hydraulic cylinder is equipped with piston rod, fixing bolt passes through mandrel pedestal far from one end of gag lever post, and remote with piston rod One end of chaotropic compressing cylinder is connected, and piston rod is equipped with the connection spiral shell matched with fixing bolt far from one end of hydraulic cylinder Hole.
Preferably, the ringfeder mandrel includes the first elastic expansion-sleeve and the second elastic expansion-sleeve, the first elastic expansion-sleeve and second The center of elastic expansion-sleeve is equipped with conical internal cavity, and two groups of conical cavity shapes are identical and mutually symmetrical with.
Preferably, the mandrel pedestal and gag lever post are respectively equipped with the first tapered portion and second close to the side of ringfeder mandrel Tapered portion, and the first tapered portion and the second tapered portion are matched with the second elastic expansion-sleeve and the first elastic expansion-sleeve respectively.
Compared with prior art, the utility model has the beneficial effects that:
1, using the flexible of hydraulic cylinder inner piston rod, to control moving up and down for gag lever post, thus controllable ringfeder core The distending of axis and recovery, and the distending degree of elastic expansion-sleeve can be controlled by the lower pan position of gag lever post, are applicable to Wheel hub in heart pore size difference, it is applied widely, and when the wheel hub of the different central hole sizes of positioning, replacement mandrel is not needed, It improves work efficiency, and reduces production cost;
2, it is zero with center interporal lacuna after elastic expansion-sleeve distending, realizes precise positioning, ensure that subsequent processing quality;
3, when rubber pad can be moved down with buffer limit bar, shock between the first tapered portion and the second tapered portion, reduction is made an uproar Sound, while extending the service life of tapered portion.
Detailed description of the invention
Fig. 1 is the maching of Al wheel positioning core axle structural schematic diagram before improving;
Fig. 2 be the utility model proposes a kind of improved the maching of Al wheel positioning core axle.
In figure:1 mandrel pedestal, 2 fixing bolts, 3 ringfeder mandrels, 31 first elastic expansion-sleeves, 32 second elastic expansion-sleeves, 4 limits Position bar, 5 hydraulic cylinders, 6 piston rods, 7 first tapered portion, 8 second tapered portion.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.
Referring to Fig.1-2, a kind of improved the maching of Al wheel positioning core axle, including mandrel pedestal 1, mandrel pedestal 1 Upside is equipped with ringfeder mandrel 3, and ringfeder mandrel 3 includes the first elastic expansion-sleeve 31 and the second elastic expansion-sleeve 32, the first elastic expansion-sleeve 31 It is equipped with conical internal cavity with the center of the second elastic expansion-sleeve 32, two groups of conical cavity shapes are identical and mutually symmetrical with, ringfeder mandrel 3 sides far from mandrel pedestal 1 are equipped with gag lever post 4, and mandrel pedestal 1 and gag lever post 4 are respectively equipped with close to the side of ringfeder mandrel 3 First tapered portion 7 and the second tapered portion 8, and the first tapered portion 7 and the second tapered portion 8 respectively with the second elastic expansion-sleeve 32 and first Elastic expansion-sleeve 31 matches, and the center of gag lever post 4, ringfeder mandrel 3 and mandrel pedestal 1 is equipped with coaxial through-hole, and in through-hole Equipped with fixing bolt 2, mandrel pedestal 1 is equipped with hydraulic cylinder 5 far from the side of ringfeder mandrel 3, and the inside of hydraulic cylinder 5 is equipped with Piston rod 6, fixing bolt 2 far from gag lever post 4 one end pass through mandrel pedestal 1, and with piston rod 6 far from hydraulic cylinder 5 one End is connected, and piston rod 6 is equipped with the connecting screw hole matched with fixing bolt 2 far from one end of hydraulic cylinder 5.
Working principle:Mandrel pedestal 1 is fixed by screws on mounting plane, when the hub diameter of processing is less than the second bullet Property ringfeder 32 diameter when, the first elastic expansion-sleeve 31 of ringfeder mandrel 3 is placed upwards, hub centre hole is installed to ringfeder core On first elastic expansion-sleeve 31 of axis 3, gag lever post 4 is driven to move down by the retraction of 5 inner piston rod 6 of hydraulic cylinder, the second tapered portion 8 With the collision between the first tapered portion 7, thus by 31 distending of the first elastic expansion-sleeve, at this time between the first elastic expansion-sleeve 31 and centre bore Gap is zero, realizes precise positioning, after processing is completed, piston rod 6 moves up, and above pushes away gag lever post 4 by fixing bolt 2, the first bullet Property ringfeder 31 natural resiliency effect under restore original state.
