Description
Technical field
It the utility model is related to the wheel hub clamp for clamping wheel hub.
Background technology
Respectively there is a flange at a, b both ends of aluminium alloy wheel hub.In order to process b ends, it is necessary to a ends clamping on chuck；For
Processing a ends are, it is necessary to b ends clamping on chuck.In automated job, in order to which wheel hub is delivered at chuck, usually use
Manipulator, its common operation process are：By the wheel hub clamp of manipulator after being picked up by a ends of the wheel hub on conveyer belt,
Deliver at the chuck of a end machining tools, then chuck clamps chuck b ends by positioning and clamping mechanism, then processes a ends.When
After a ends completion of processing of wheel hub, then wheel hub a ends after a ends are processed by the wheel hub clamp of manipulator are clamped, and then unclamp a
Wheel hub is removed placement somewhere by the clamping positioning mechanism of end machining tool, manipulator from a end machining tools, and then wheel hub presss from both sides
Pincers unclamp a ends.Then, wheel hub clamp delivers to the chuck of b end machining tools again after being picked up by the b ends of the wheel hub on conveyer belt
Locate, then chuck clamps chuck a ends by positioning and clamping mechanism, then processes b ends.
As can be seen here, when chuck positions clamping to one end of wheel hub, what wheel hub clamp clamped is the other end of wheel hub.In order to
Positioning accurate to wheel hub clamps, very high for the status requirement of wheel hub clamp.If the position of wheel hub clamp is by having a little partially
Difference, due to the other end that one end of wheel hub clamp clamping clamps away from chuck positioning, the deviation will produce amplification at chuck
Effect, the hub positions deviation for causing locating clip next is larger, and the wheel hub precision after so processing is difficult to ensure.
The content of the invention
The purpose of this utility model is to provide one that a kind of positioning and clamping mechanism by chuck that can clamp wheel hub clamps
End, ensure chuck accurate positioning, reduce the wheel hub clamp of deviation.
Wheel hub clamp of the present utility model, it includes at least one pair of clamp being arranged on clamp seat, and each pair clamp includes
The jig arm of two relative foldings, there is two roller shafts in each jig arm, and a roller is respectively set at the both ends of each roller shaft,
Two rollers on same roller shaft are located at the both sides of jig arm；There is circumferential groove on the periphery of each roller, positioned at two
Circumferential groove on the four rolling of jig arm the same side is respectively positioned in approximately the same plane；The narrow top width in circumferential groove bottom of roller, ring
Into two sides of groove, a side and roller axis are substantially vertical（With roller axis about into 85-90 ° of angle）；It is another
Individual side and roller axis are into 30-70 ° of angle；With roller axis substantially vertical side relative to another side in roller shaft
Line side is upwardly away from jig arm.
The beneficial effects of the utility model：Due to respectively there is four rolling in the both sides of jig arm, and the roller per side is respectively positioned on
The end of roller shaft.When one end of the four rolling clamping wheel hub in approximately the same plane, jig arm and other four rollings
Outside of the wheel at the periphery of wheel hub, interference will not be produced with chuck.That is, wheel hub clamp can clamp wheel hub one
End, and the end close to chuck so that chuck positioning and clamping mechanism can clamp the one end clamped by wheel hub.This, both
Make the position slightly deviation of wheel hub clamp, in the rational scope that can be also controlled by the next wheel hub of chuck locating clip, ensure
Crudy.
Because with circumferential groove, when the flange of hub end is extend into groove, two jig arm are relative to close up so that rolling
Wheel is when clamping flange, with roller axis into the side of 30-70 ° of angle（That is medial surface）So that wheel hub hangs down substantially to roller axis
Straight sided（That is lateral surface）Mobile, an end face of wheel hub just contacts with lateral surface, forms axially position.Because roller is clamped in
The outer rim of the wheel hub end face, it can make it that the wheel hub end face is as vertical with the holding of hub centre line as possible.The shape of annular groove
The die slot flash in the wheel hub end face outer rim can also be avoided to be contacted with the bottom surface of annular groove, central wheel axis will not be caused
Deflection.
Above-mentioned wheel hub clamp, roller are rotatably arranged on roller shaft.
Above-mentioned wheel hub clamp, roller shaft are rotatably arranged in jig arm.
Above-mentioned wheel hub clamp, two pairs of clamps are set on clamp seat.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to the wheel hub clamp shown in Fig. 1,2, it includes two pairs of clamps 3 being arranged on clamp seat 2, and each pair clamp includes
Two can be with respect to the jig arm 31,32 of folding.Rotated in each jig arm and be provided with two roller shafts 41,42, two rollers 51,
52 are rotatably arranged on the both ends of each roller shaft respectively.Two rollers 51,52 on same roller shaft are respectively positioned at jig arm
Both sides.
Referring to Fig. 5, the structure of four rolling 51 in jig arm the same side is identical, has ring recessed on the periphery of each roller 51
Groove 6.The narrow top width in circumferential groove bottom, it has lateral surface 61, bottom surface 62, medial surface 63.Lateral surface is substantially vertical with roller axis（Into
85-90 ° of angle）；Medial surface 63 and the axis of roller 51 are into 45-60 ° of angle.Lateral surface is relative to medial surface in roller axis side
It is upwardly away from jig arm.Circumferential groove on four rolling 51 is respectively positioned in approximately the same plane.
It is identical in the structure of four rolling 52 of jig arm opposite side referring to Fig. 6, have ring recessed on the periphery of each roller 52
Groove 7.The narrow top width in circumferential groove bottom, it has lateral surface 71, medial surface 73.Lateral surface 71, medial surface 73 and the axis angle of roller 52
It is identical, about 45-60 °.Circumferential groove on four rolling 52 is respectively positioned in approximately the same plane.
Referring to Fig. 7, in use, passing through the clamping wheel hub of four rolling 51 on clamp（Blank）8 a ends 81, a ends is close
At the chuck 9 of b end machining tools, then chuck clamps wheel hub a ends by positioning and clamping mechanism 91, then processes wheel hub b ends
82.The wheel hub b ends after the processing of b ends are clamped after the b ends completion of processing of wheel hub, then by the four rolling 52 on clamp, so
The clamping positioning mechanism of b end machining tools is unclamped afterwards, after wheel hub is removed placement by manipulator from b end machining tools, is sent to a ends
Machining tool.Manipulator is wheel hub b ends at the chuck 9 of a end machining tools, and then chuck passes through positioning and clamping mechanism 91
Chuck b ends clamp, and then process a ends.So this wheel hub completion of processing.
When wheel hub one end is close to chuck, because jig arm 3 is close to the periphery of wheel hub, rather than positioned at chuck and wheel hub it
Between, and the roller one end for only clamping wheel hub is clamped between chuck and wheel hub so will not be clamped to chuck by roller
Wheel hub one end cause to interfere.
Referring to Fig. 5, at 51 clamping wheel hub a ends of roller, the inclined medial surface 63 of roller 51 is upward along axis to wheel hub
Sliding force, the end face 83 at wheel hub a ends is contacted with the lateral surface 61 of roller 51, formed axially position.Circumferential groove is special
Although the matched moulds sewer being shaped such that at the periphery of a ends has flash 84, flash will not contact with circumferential groove bottom surface 62, prevent from taking turns
Hub axle line produces skew.
For roller 52 although with the roller structure of routine, single wheel hub b ends due to roller clamping are after processing, so b
The presence of flash is there will be no at end, therefore roller 52 will not be had an impact using conventional roller to the positioning of wheel hub.
