It is collided in stress test equipment in a kind of above-mentioned vehicle hub, the cochain wheel system 2 and lower sprocket system 20 It is rotatably connected on interior outer column upper plate 5 and the bottom of the test chassis respectively, as shown in figure 25, reel motor 86 drives Spool body 93 rotates clockwise, and chain is wrapped on reel, and chain lifts clamping jaw to setting height at this time；And spool body 93 is inverse Hour hands rotation, chain are detached from from reel, and chain will be laid down at this time.
As shown in Fig. 2, colliding in stress test equipment in a kind of above-mentioned vehicle hub, the test equipment further includes inserting Elevating mechanism is sold, the bolt elevating mechanism includes bolt lift adjustment screw rod 27, and the lower end of the adjusting screw rod passes through connection Axis device 43A couples with bolt lift adjustment AC servomotor 44, and the bolt lift adjustment screw rod top is threaded with Bolt lift adjustment bolt and nut 33 is fixed on four bolt of opposite opened at the top of the bolt lift adjustment bolt and nut and just slides On pedestal base 31, the bottom plate is mounted with the positive plain bearing housing bottom plate mounting bracket 32 of four bolt of opposite opened and ball bearing guide bushing 30 are mounted in this bracket, this ball bearing guide bushing and positive plain bearing housing bottom plate lifting 29 row of correcting column of four bolt of opposite opened are at rolling Dynamic kinematic pair.
Bolt lift adjustment screw rod 27 and bolt lift adjustment bolt and nut 33 constitute screw pair, and servo motor driving is adjusted Screw rod rotation, adjusting screw rod increase the rotation of bolt lift adjustment bolt and nut or rotation declines, bolt lift adjustment screw rod spiral shell Master tape moves bottom plate and rises or falls, which can be according to the possibility height of hammer body bounced, to precondition the height of bolt, this Sample can make bolt be inserted into hammer body bottom with most fast speed, when hammer body is located at extreme higher position, bolt can be made close as far as possible The bottom of hammer body, after falling behind under hammer body and encountering bolt, the impulsive contact force that bolt is subject to is minimum, and this makes it possible to be easier to stop Hammer body decline, also can avoid bolt from being damaged well.
It is collided in stress test equipment in a kind of above-mentioned vehicle hub, the test equipment further includes 31 opposite opened, four spiral shell Fixed there are four electromagnet is held tightly on the positive plain bearing housing bottom plate of bolt, each electromagnet is located at corresponding 29 opposite opened, four bolt The side of positive plain bearing housing bottom plate lifting correcting column, the other side of each correcting column slidably connect one 54 holding armature, when When 55 bolts hold electromagnet energization tightly, holding electromagnet tightly, holding armature can be sucked, and the two holds corresponding correcting column tightly, When hammer body strikes bolt, the structure can relatively flexible holding correcting column, be conducive to mitigate to 27 bolt lift adjustment spiral shells The rigid collision of bar makes bolt have better blocking effect to hammer body.
As shown in figure 4, described when hammer body strikes wheel hub tire, hammer body may be bounced higher, be met or exceeded Tire is former highly, and in the structure, when push-and-pull bolt electromagnet 50 powers off, the push-and-pull release of bolt compressed spring 48 extends, and makes bolt It packs up；When pushing and pulling the energization of bolt electromagnet 50, push-and-pull bolt compressed spring 48 is compressed, and bolt is ejected, and bolt is outer at this time Hammer body impact force suffered by end can pass to bolt lift adjustment screw rod 27, hammer body can be stopped to fall at this time, the knot Structure can prevent hammer body from carrying out secondary collision to wheel hub tire.
Substantially there are so several situations of dropping hammer to need to control when above-mentioned wheel hub tire is dropped hammer and collided；
As shown in figure 4, dropping hammer above-mentioned into when falling program, first element is that push-and-pull bolt electromagnet 50 powers off, Push-and-pull bolt compressed spring 48 works, and bolt 52 is packed up, and bolt is guided by three positive plain bearing housings 51 of four bolt of opposite opened, With ensure bolt accept hammer body fall generate impulsive contact force and be unlikely to be broken, share four root cutting pins, just have 12 it is split The positive plain bearing housing 51 of four bolt of formula guides, and lives hammer body with ensure card, is unlikely to the folded over bolt of collision that hammer body falls.It is right The positive plain bearing housing 51 of four bolt of open type is mounted on positive 47 bottom plate of plain bearing housing of four bolt of opposite opened, as shown in Fig. 2, this Bottom plate is mounted in the positive plain bearing housing bottom plate mounting bracket 32 of four bolt of opposite opened, this bracket and bottom plate are mounted with that ball is led Set 30, this ball bearing guide bushing have guided the positive plain bearing housing bottom plate lifting correcting column 29 of four bolt of opposite opened, this bottom plate and bracket are also It being connected with bolt lift adjustment bolt and nut 33, this nut and bolt lift adjustment screw rod 33 become screw pair, and screw rod rotates, Nut rises and decline, and bottom plate and bracket rise and decline immediately.Clamping jaw electromagnet 139 powers off, and clamping jaw unclamps, and hammer body is fallen, There are three types of situations at this time:
1, the rigidity of above-mentioned wheel hub enough, drop hammer when striking wheel hub tire, dropping hammer, it is higher to be bounced, and meets or exceeds The former height of tire；
2, the rigidity of above-mentioned wheel hub not enough, drop hammer when striking tire, hammer body, which is not bounced, meets or exceeds tire Former height；
3, poor in the rigidity of above-mentioned wheel hub, it drops hammer when striking tire, directly just wheel hub is pounded routed, hammer body is directly Fall；
For this above-mentioned three kinds of situation, the location matches and movement matching of photoelectric sensor and bolt are discussed；
As shown in Figure 1, the photoelectric sensor 18 is mounted on installation photoelectric sensor shelf 10, be mounted on away from tire or At slightly upper 3 to 10 millimeters of detectable substance of being dropped hammer top substitution height, the substitution eminence dropped hammer so has just first blocked photoelectric sensing The light that device issues, photoelectric sensor just first start, and starting has a time difference (blocking reaction time), this time difference can make It drops hammer when pounding tire, the electromagnet of bolt starts, this has a time difference again, and such bolt front fork acts and is just inserted to the bottom dropped hammer Portion, there is a circular arc on the head of bolt, easy to be inserted into bottom of dropping hammer.
In the first above-mentioned situation, drop hammer and bounce, the shading light part for the substitution height dropped hammer is covered, photoelectric sensor without Closing is blocked, bolt is inserted into bottom of dropping hammer, and the depth of insertion is greater than the logical head radius of bolt circle, and this prevents secondary punchings It hits.
It in above-mentioned second situation, drops hammer and does not bounce, such bolt does not just work, just without preventing secondary collision ?.
In the third above-mentioned situation, and it is not necessarily to prevent secondary collide.
There is a difference in above-mentioned different diameter of tyres, several photoelectric sensor (12 inch, 14 to be thus installed Inch, 16 inch, 18 inch, 20 inch, 22 inch, 24 inch, 26 inch) totally eight, it is assumed that the diameter of wheel hub is straight for maximum tire plus 60 millimeters Diameter, the installation site of photoelectric sensor will adapt to the wheel hub tire of such different-diameter, different height, in test specific size Wheel hub when, first stop the work of remaining photoelectric sensor.
Such as Fig. 9, bolt is inserted into hammer body bottom " standard type and adjusting type line slideway auxiliary " figure.
The accurate of wheel hub tire is first measured before colliding test wheel hub according to various sizes of wheel hub first above-mentioned This data is inputed to the disk having inside 44 bolt lift adjustment servo ac motors by radius (half diameter) As soon as encoder signal, disk coder gives the lap signal of rotation to 44 servomotors, and servomotor is i.e. by bolt Shank diameter top is adjusted to the place of the top slightly higher 2mm to 3mm in the collision face of wheel hub tire, and such hammer body collides wheel hub tire When rebound is jumped up afterwards, the time that bolt rises to hammer body bottom will be relatively fast.The zero-bit of this disk coder is set in On the central axis of hub spindle.
The reaction time value of the photoelectric sensor 0.1 second, 3000 turns of the revolution value of servomotor/per second, if: 1, being takeoff after hammer body collision to lowering time is 1 second, bolt lift adjustment screw rod 27 and bolt lift adjustment bolt and nut 33 Screw pitch is 3 millimeters, then:
(1-0.1=0.9 second)
0.9 × 3000=2700 (turns)
2700 × 3=8100 (millimeter)
The height that 1:1 seconds temporal interpolation pin lift adjustment screw rods 27 of conclusion can rise or fall is 8100 millimeters, this The servomotor reaction time surplus of sample is big.
2, such as when hammer body collision after takeoff to lowering time be 0.2 second when:
0.2-0.1=0.1 (second)
0.1 × 3000=300 (turns)
300 × 3=900 (millimeter)
The height that 2:0.2 seconds temporal interpolation pin lift adjustment screw rods 27 of conclusion can rise or fall is 900 millimeters, this The servomotor reaction time of sample is enough.
3, it asks: when the height that bolt lift adjustment screw rod 27 rises is enough as long as 150 millimeters, being provoked after hammer body collision It is equal to fall time how many?
If: it takeoffs after hammer body collision and is equal to x to fall time
Solution: x-0.1 is equal to the working time for leaving servomotor after photoelectric sensor reacts for
(x-0.1) × 3000 the rotating cycle of axis when being equal to servomotor work
(x-0.1) × 3000 × 3=150 (millimeter)
Then x=0.1167 seconds
Conclusion 3: it when the height that bolt lift adjustment screw rod 27 rises is 150 millimeters, takeoffs after hammer body collision to whereabouts Time is equal to 0.1167 second.
That is: hammer body collision after takeoff to fall time be 0.1167 second when, bolt lift adjustment screw rod 27 rise Height can achieve 150 millimeters.
Conclusion: the reaction speed of this servomotor is enough.
(by the type selecting of photoelectric sensor at 3 to 10 millimeters of the substitution height that above-mentioned photoelectric sensor is mounted on tire This fixed distance), usually enter light closing, (entering light ON), bolt holds electromagnet 55 tightly and do not work, and bolt 52 does not work, hammer Body rises and rises to setting height, and then clamping jaw unclamps, and hammer body freely falling body is fallen, if the bottom of hammer body is away from tire top surface distance H1 installs photoelectric sensor (the light beam lower part light limit of photoelectric sensor at 3 to 10 millimeters of tire top substitution height 3 to 10 millimeters of place's distance substitution height), interdicting light source herein has reflection, and dropping hammer to fall 3 to 10 millimeters and encounter the tire used time is T1, hammer body collide tire after by tire rebound pop up the used time be T2, light source restores into light (entering light ON), T1+ at this time Two times of T2 are added, and are set as the reaction time of photoelectric sensor, at this point, when T1 occurs, as shown in Fig. 2, a signal is just Bolt lift adjustment AC servomotor 44 has been given, at this point, bolt lift adjustment screw rod 33 rotates, bolt lift adjustment nut 33 can move up and down, and rise at this time, as shown in figure 4, the positive plain bearing housing bottom plate of four bolt of opposite opened being coupled 47 just lift the rising of bolt group body, until hammer body bottom is inserted into when T1+T2, it is (short instantaneous before bolt is inserted into hammer body bottom Between), bolt holds electromagnet 55 tightly and receives power on signal, and armature 54 is held electromagnet 55 tightly by bolt and is attracted, as shown in Figure 1, holding tightly The positive plain bearing housing bottom plate of opposite opened four bolt goes up and down correcting column 29, this guide post must not have greasy dirt, and electromagnet holding is led at this time Column is the holding of a relative stiffness, higher in this way because not knowing the height that hammer body can be repelled in advance, then hammer body impacts Power will have a biggish collision to bolt and conduct to bolt lift adjustment screw rod 27, and bolt is fixed at a distance from electromagnet , holding first carry out, and then bolt be inserted into hammer body bottom, this is carried out immediately, hold tightly and bolt block be it is integrated, be Dual fail-safe setting, be unlikely to the rigid collision dropped hammer to bolt because bolt lift adjustment screw rod 27 be it is relatively rigid, this When, hammer body is to collide a little to bolt, and electromagnet is held tightly, bolt is inserted into, and alleviates being rushed for bolt lift adjustment screw rod 27 It hits, this is held tightly and is inserted into and bolt lift adjustment screw rod 27 is formed together three insurances, and hammer body is stuck at this time, it is therefore prevented that hammer body Secondary collision to wheel hub.
