Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the utility model embodiment synoptic chart;
Fig. 2 is Fig. 1 embodiment A part enlarged drawing;
Fig. 3 is Fig. 1 Embodiment B part enlarged drawing.
Embodiment
As shown in Figure 1, the utility model embodiment synoptic chart.Pallet 500 is fixed in a vertical rotating shaft 510, and activity is fixed on the base 100; Pallet 500 can be stablized rotation with rotating shaft 510 in surface level.Its shaft 510 is driven by the motor 101 in the base 100.
Directly over pallet 500, has a platen drive unit 310, this platen drive unit 310 is fixed in base 100 by a support 200, and its bottom has a clamping head 300, and this clamping head 300 is matched with support 200 by two guide rod 330 activities; Clamping head can guide rod 330 for guiding up and down, clamping or discharge coaxial moveable platen 400 under it.
Fig. 2 is Fig. 1 embodiment A part enlarged drawing, and this part has mainly been showed the details of clamping head 300.As figure, the shell of reciprocating air cylinder 301 is fixed on the support 200, and its inner piston 302 is affixed with clamping head, and two horizontal relative clamping cylinders 303 and downward disconnector 304 are arranged on the clamping head;
Fig. 3 is Fig. 1 Embodiment B part enlarged drawing, and this part has mainly been showed the details of moveable platen 400 and centering cone 420.As figure, platen main body 410 is a tubular; Two latches 412 of platen main body 410 its stage casing inwall cross-under, these two latches 412 are with 180 ° of symmetrical distributions of rotating shaft 510 central axis.As can be seen from Figure, touch part mutually at rotating shaft 510 and latch 412 and have some convex annular ring gears, and latch 412 meshes therewith, the structure of this engagement makes latch 412 axially can't the moving of rotating shaft 510, thereby the moveable platen 400 among platen main body 410 and even whole Fig. 1 is axially fixed in the rotating shaft 510.Latch 412 is to control by the disengaging inclined-plane 413 on its top, is touched by the outside, 304 lower ends of the disconnector among Fig. 2.
Below platen main body 410, telescopic 414 of pivot bush unit, these telescopic 414 sockets rotating shaft 510.Between the turning down face 421 of the surface of revolution 415 on the telescopic 414 and centering cone 420 is to be measured 600.
Below on operation, the principle of work of entire mechanism is described in conjunction with Fig. 1 to Fig. 3:
Centering: to be measured 600 of wheel hub passes rotating shaft 510 from the top, is placed on the pallet 500, and the cone of feeling relieved this moment 420 is inserted to be measured 600 center through hole, determines to be measured 600 rotation center;
This moment, moveable platen 400 whole clamped cylinders 303 were held on platen drive unit 310, were suspended from directly over to be measured 600; When to be measured 600 be placed centering after, reciprocating air cylinder 301 starts, piston 302 is descending, moveable platen 400 is pressed down, pass rotating shaft 510, the center through hole upside that telescopic 414 is pressed to be measured 600, this state, the last surface of revolution 415 of telescopic 414 is relative to compressing to be measured 600 with the turning down face of qualitative cone 420 421;
Locking: after finishing above-mentioned steps, clamp cylinder 303 and discharge platen main body 410, disconnector 304 closures are so latch 412 is radially gathered to rotating shaft 510 in rotating shaft 510, make whole moveable platen 400 lock onto rotating shaft 510 in the axial direction, this moment, clamping head 300 whole making progress bounced back.Therefore, to be measured 600 is locked on pallet 500.
Rotation: under this state, motor 101 drives rotating shaft 510, to be measured 600 rotation, finishes jitter values and detects.
Finish: after detection finished, reciprocating air cylinder 301 promoted clamping heads 300 and descends, and disconnector 304 is opened, latch 412 outer opening, and moveable platen 400 is able to and rotating shaft 510 releasing locking states; Reciprocating air cylinder 301 makes clamping head 300 retractions once more, clamps cylinder 303 and drives moveable platen 400 whole disengaging rotating shafts 510, makes to be measured 600 and can detach rotating shaft 510 easily, so far, finishes one to be measured detection circulation.
Circulation as can be known thus, to be measured 600 placement and disengaging, because action is simple, all can adopt automation equipment to finish, remove artificial intervention fully, this makes that whole detection circulation can be that the robotization mode realizes, so this mechanism can directly apply to automatic production line, and be that product is examined entirely, this has guaranteed the yields of product 100% dramatically, and its precision, speed can be guaranteed.Simultaneously, present embodiment is applicable to the solid of revolution of all similar wheel hub structures, has very big versatility.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
