Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention one comprises:
As shown in Figure 1, a kind of location and protection mechanism of floating, comprises upper flange plate 2, lower flange 3, gauge head mount pad 1, slide bar or slide rail 5 and slide block 6, and described gauge head mount pad 1 is through described upper flange plate 2, lower flange 3.Gauge head mount pad 1 through upper flange plate 2 and lower flange 3 place outer peripheral face and all have gap 9 described upper flange plate 2 and lower flange 3, the top of gauge head mount pad 1 is fixed with gauge head 10.
The outer peripheral face at the middle part of described gauge head mount pad 1 there is the transition disc 13 of protrusion, transition disc 13 is between upper flange plate 2 and lower flange 3, the upper and lower end face of transition disc 13 and all have gap between described upper flange plate 2 and lower flange 3, the end face that described upper flange plate 2 is corresponding with the upper and lower end face of transition disc 13 with lower flange 3 is provided with the ring raceway 8 of depression, ring raceway 8 is the groove of annular.Rotatable spheroid 12 is provided with in ring raceway 8, long rod 18 is had to pass in described upper flange plate 2 and lower flange 3, one end of described long rod 18 is stretched in described upper flange plate 2 and is threaded with described upper flange plate 2, the other end of described long rod 18 stretches out outside described lower flange 3, the described other end of described long rod 18 there is external screw thread, described external screw thread place is furnished with nut 15, and the long rod 18 between described lower flange 3 and described nut 15 overlaps Compress Spring 14.
The weight balancing of the elastic force that produces of Compress Spring 14 and the upper flange plate 2 of its carrying, lower flange 3 and gauge head mount pad 1 under normal circumstances, Compress Spring 14 pairs of upper flange plates 2, lower flange 3 and gauge head mount pad 1 have float support effect.Turn the elastic force that nut 15 can regulate Compress Spring 14 to produce.Upper flange plate 2, lower flange 3 and gauge head mount pad 1 couple together by long rod 18 and Compress Spring 14.
Had good positioning in the manipulator of measurement device or the position of automatic charging device, and measuring position does not have large deviation accurately, but may have minor departures when each manipulator or automatic charging device work.When measuring part, manipulator or automatic charging device take part to be measured to gauge head 10 place, are put in the detect aperture in gauge head 10 by part to be measured.If part to be measured is just positioned at the accurate measuring position of detect aperture, then whole measuring mechanism is in poised state.If part to be measured has small deviation in detect aperture, active force can be produced when part then to be measured contacts with detect aperture, gauge head mount pad 1 and gauge head 10 can carry out floating or tilt rotation of small horizontal direction in gap 9 under this force, make part to be measured finally can be positioned at accurate measuring position.
Multiple spheroid 12 can freely billow dynamic in ring raceway 8, does not affect gauge head mount pad 1 and gauge head 10 meeting floating or tilt rotation in gap 9.
Described slide bar or slide rail 5 are fixed on on described floating location and the matching used equipment of protection mechanism; described slide block 6 is set on described slide bar or slide rail 5; described lower flange 3 or upper flange plate 2 are fixedly connected with described slide block 6; one end of described slide bar or slide rail 5 is provided with elastomeric element 7, and described elastomeric element 7 or cylinder withstand described one end of slide bar or slide rail 5.Elastomeric element 7 be spring or other can produce the device of elastic force.

Under normal circumstances, when on manipulator or automatic charging device take qualified part to be measured to gauge head 10, slide block 6 can not slide, and slide block 6 is in poised state under the resilient support of elastomeric element 7, the top of slide block 6 contact with sensor 11 or from very close to.When on manipulator or automatic charging device take defective or undressed part to be measured completely to gauge head 10, part to be measured can not normally be put into inspection opening in gauge head 10.Now part to be measured can produce to gauge head 10 active force pressed down, and elastomeric element 7 is compressed, and slide block 6 glides, and the top of slide block 6 is separated with sensor 11 or becomes large with the distance of sensor 11.Sensor 11 can send signal to manipulator or automatic charging device; manipulator or automatic charging device is made to stop moving down blowing; also manipulator or automatic charging device can be made further to increase with part to be measured return; avoid manipulator or automatic charging device to move down with part to be measured always and break gauge head 10; also manipulator or automatic charging device self is avoided to be broken; thus gauge head 10 and manipulator or automatic charging device are protected, prevent manipulator or automatic charging device error job.
Preferably, the upper and lower end face of described transition disc 13 and the gap between described upper flange plate 2 and lower flange 3 are less than the radius of described spheroid 12, make spheroid 12 can not depart from ring raceway 8.
Preferably, the center line of described lower flange 3 and upper flange plate 2 and the centerline parallel of described slide bar or slide rail 5.
Preferably, described long rod 18 is arranged with sleeve 4, and described sleeve 4 is between described lower flange 3 and described nut 15.
Preferably, described upper flange plate 2 or be provided with connecting plate 16 between lower flange 3 and described slide block 6, described upper flange plate 2 or lower flange 3 are fixedly connected with described slide block 6 by described connecting plate 16.
Preferably, described long rod 18 is 3, arranges for described 3 long excellent 18 in equilateral triangle, and long rod 18 pairs of upper flange plates 2 that 3 equilateral triangles are arranged and lower flange 3 and gauge head mount pad 1 have better balanced action.
Spheroid 9 adopts high-abrasive material, and strong shock resistance is non-friable, to ensure its service life.
The embodiment of the present invention two:
As shown in Figure 2, the embodiment of the present invention two is that cylinder 17 instead of elastomeric element 7 with the difference of embodiment one, and remainder is identical with embodiment one.The effect of cylinder 17 is also support slipper 6, when manipulator or automatic charging device with underproof to be measured or part to be processed presses to gauge head 10 or processing stations time, when the pressure produced is greater than the equilibrant force that cylinder 17 provides, slide block 6 will move down, and the top of slide block 6 is separated with sensor 11 or becomes large with the distance of sensor 11.Sensor 11 can send signal to manipulator or automatic charging device; manipulator or automatic charging device is made to stop moving down; also manipulator or automatic charging device can be made further to increase with part to be measured return; avoid manipulator or automatic charging device to move down with part to be measured always and break gauge head 10; also manipulator or automatic charging device self is avoided to be broken; thus gauge head 10 and manipulator or automatic charging device are protected, prevent manipulator or automatic charging device error job.
Pass through the level of gauge head 10 like this and tilt to float, the detection position of part to be measured on gauge head 10 can be adjusted by trace, make part to be measured be in accurate measuring position, accurately locate.The distance change of simultaneously upper and lower Z-direction can control gauge head 10, manipulator or automatic charging device and do not broken.
