Utility model.
Specific embodiment
In order to further illustrate the principle of the present invention and structure, the preferred embodiment of the present invention is carried out in conjunction with attached drawing detailed
It describes in detail bright.
As shown in Figure 1 to Figure 3, Fig. 1 is that the positioning tool for wheel hub processing of the utility model positions wheel hub
When dimensional structure diagram, Fig. 2 be the utility model for wheel hub processing positioning tool wheel hub is positioned when
Side view, Fig. 3 are the top view when positioning tool for wheel hub processing of the utility model positions wheel hub.This practicality
The new positioning tool 10 for wheel hub processing includes bottom plate 11, supporting mechanism 12, chuck mechanism 13, angular detent mechanism 14
And hold-down mechanism 15.Supporting mechanism 12, which is fixed on bottom plate 11, is used to support wheel hub 20.Chuck mechanism 13 is fixed on bottom plate 11
Above and in the region that supporting mechanism 12 surrounds, for being positioned in the axial direction to wheel hub 20.Angular detent mechanism
14 are fixed on the fringe region of bottom plate 11, for being positioned in circumferential direction to wheel hub 20.Hold-down mechanism 15 is used to take turns
The top surface of hub 20 compresses wheel hub 20.
With reference to shown in Fig. 4, for the supporting mechanism of display the utility model and the structure diagram of hold-down mechanism.Support machine
Structure 12 includes multiple support columns 121, and the top surface of those support columns 121 matches with the petal boss 23 on the flange 22 of wheel hub 20
It closes, to support entire wheel hub 20.Those support columns 121 surround a circle on bottom plate 11, and the size of the circle diameter is according to wheel
The size of hub 20 determines.The height of the support column 121 is adjustable, including the supporting block 1211 positioned at top and positioned at branch
Multiple dismountable cushion blocks 1212 of 1211 lower section of bracer, supporting block 1211 are detachably connected with multiple cushion blocks 1212 by connector

Positioning tool 10 is realized in the axial direction by chuck mechanism 13 to wheel hub by 12 supporting wheel hub 20 of supporting mechanism
20 positioning is realized the positioning to wheel hub 20 by angular detent mechanism 14, is being taken turns by hold-down mechanism 15 in circumferential direction
The top positioning wheel hub 20 of hub 20, thereby the positioning tool 10 realizes the positioning to wheel hub 20 from all directions, and then improves
The repetitive positioning accuracy of wheel hub 20.
The utility model separately provides a kind of wheel hub system of processing, including above-mentioned 10 He of positioning tool for wheel hub processing
Aperture knife tool.The aperture knife tool includes two sets of cutters, and a wherein tooling is used to process the threaded hole 24 on wheel hub top surface
(as shown in Figure 1), another set of cutter are used to process the bolt hole 21 (as shown in Figure 1) on the flange of wheel hub.
After positioning tool is completed to the positioning of wheel hub, aperture knife tool carries out drilling processing to wheel hub, in wheel hub top surface
Multiple threaded holes for processing and multiple bolts hole are processed on the flange of wheel hub.
Specifically, the processing method of the wheel hub system of processing is as follows:
Step 1, by the supporting mechanism 12 of positioning tool 10, chuck mechanism 13, angular detent mechanism 14 and hold-down mechanism 15
On bottom plate 11.
Wheel hub 20 is hung at the top of positioning tool 10 by step 2, makes the axis of the bearing hole of wheel hub 20 and chuck sheet
The axis alignment of body 131, wheel hub 20 is slowly put down, wheel hub 20 is made to fall in the periphery of chuck body 131, the flange 22 of wheel hub 20
Petal boss 23 fall top surface in support column 121.
Step 3, the angle of rotary hub 4 make the petal boss 23 of required positioning opposite with angular detent mechanism 14, push away
Move the guide rod 144 of angular detent mechanism 14 so that locating piece 146 fastens with petal boss 23, with solid in circumferential direction
Fixed wheel hub 20.
Step 4 pulls the handle 162 of air operated reversing valve 16, struts claw block 132,132 apical grafting wheel hub 20 of claw block
The inner wall of bearing hole, to position wheel hub 20 in the axial direction.
Step 5 tightens the nut 153 of hold-down mechanism 15, and platen 152 is made to compress wheel hub.
Step 6 presses the aperture knife tool button on lathe, and aperture knife tool starts to be processed wheel hub, to take turns
The multiple threaded holes 24 (as shown in Figure 1) and multiple bolts are processed on the flange of wheel hub 20 that the top surface of hub 20 processes
Hole.
Step 7 after completion of processing, unloads lower hub, blows off the iron filings on wheel hub.
It repeats the above steps, carries out the processing of next wheel hub.
The positioning tool of the utility model by setting supporting mechanism, chuck mechanism, angular detent mechanism and hold-down mechanism,
Realize the positioning to wheel hub all directions, in addition, chuck mechanism can inwardly be gathered or outwards strut, and the chuck when outwards strutting
The claw block of mechanism can apical grafting hub spindle bearing bore inner wall so that between being not present between the inner wall of the bearing hole of claw block and wheel hub
Gap improves the positioning accuracy of hub spindle bearing bore, avoids manually debugging positioning repeatedly, has saved the time, improved efficiency, also carry
High repetitive positioning accuracy between wheel hub and positioning tool, and then improve the bolt hole of wheel hub and the machining accuracy of threaded hole.
The wheel hub system of processing of the utility model improves frock by the way that above-mentioned positioning tool is set to position wheel hub
Repetitive positioning accuracy between wheel hub thereby reduces the position degree of wheel hub drilling class size so that aperture knife tool can be with
Using higher cutting parameter, processing efficiency is improved.
It these are only the preferable possible embodiments of the present invention, not limit the scope of the invention, it is all with the present invention
Equivalent structure variation made by specification and accompanying drawing content, is all contained in protection scope of the present invention.
