Detailed description of the invention
Embodiment for being arranged on the fixture on sucker of the present invention: as shown in Figures 1 to 4, this fixture is made up of two elastic card claws 2 that clamp body 1, clamp body 1 are wholely set, the lock sleeve 3 that is set in elastic card claw 2 periphery.The side of clamp body 1 is convexly equipped with the columned protuberance 1-1 being in elastic card claw 2 root, another side is the adhesive face for coordinating with sucker, this adhesive face is adhesive plane, and on clamp body 1, offer opening be in the Blind locating holes 1-2 coordinated in plane, the bearing of trend of Blind locating holes 1-2 with coordinate plane orthogonal.Elastic card claw 2 erects on described protuberance 1-1, and on protuberance 1-1, offer the blind cavity 1-3 that the gap between two elastic card claws 2 is communicated with.The semi-circular cylindrical elastic card claw 2 of two elastic card claws 2 to be the involutory cross section be arranged on clamp body 1 be C type, elastic card claw 2 is can the radial card-tight part 2-1 upheld away from one end of described protuberance 1-1, and on card-tight part 2-1, is convexly equipped with gear along 2-2.Lock sleeve 3 is coordinate with the fastener stoping card-tight part to expand outwardly with elastic card claw radial direction is spacing, one end coaxial threaded of lock sleeve 3 is connected on the protuberance 1-1 on clamp body 1, the other end is set on the periphery of elastic card claw 2, and correspondingly on lock sleeve 3 and elastic card claw 2 being provided with adaptive cooperation voussoir 4, on the cooperation voussoir 4 on lock sleeve 3 and elastic card claw 2, correspondence is provided with and coordinates inclined-plane 4-1.
The present invention in use, first unscrews lock sleeve 3, makes the card-tight part 2-1 of elastic card claw 2 be flared to home position; Then, by workpiece 5(i.e. optical lens workpiece 5) be fastened between two elastic card claws 2, the edge of workpiece 5 is coordinated along 2-2 block with gear; Then screwing lock sleeve 3, make elastic card claw 2 in the process of lock sleeve 3 precession, by cooperation voussoir 4 coordinating the cooperation between inclined-plane 4-1, two elastic card claws 2 are shunk, so that workpiece 5 being clamped between two elastic card claws 2; Finally the clamp body 1 being equiped with workpiece 5 is arranged on sucker, namely by this fixture, workpiece 5 has been positioned on sucker.
The present invention in use, workpiece 5 is clamped on clamp body 1 by the gear on the card-tight part 2-1 of elastic card claw 2 and card-tight part 2-1 along 2-2, be fixed on sucker by clamp body 1 again, thus by the suction-combining force between clamp body 1 and the mating surface of sucker, reach and fixture is fixed the object on sucker together with workpiece 5, and it is spacing by the radial direction of card-tight part 2-1 to workpiece 5, gear is along the axial limiting to workpiece 5, and then the accurate location realized workpiece 5, ensure that workpiece 5 can not offset in process, ensure that the Form and position error of finished product meets processing request, the opening of Blind locating holes 1-2 is in adhesive plane, thus the component sucker the suction-combining force acted on clamp body 1 being comprised act on the component in adhesive plane and act on the hole wall of Blind locating holes 1-2, wherein acting on this part component on the hole wall of Blind locating holes 1-2 can the position of locating clip concrete 1 on sucker, stop the movement of clamp body 1 on sucker, play the effect of positioning workpieces 5 position on sucker further, the lock sleeve 3 being set in elastic card claw 2 periphery can play the effect of fastening elastic card claw 2 position, lock sleeve 3 is coordinated with the voussoir of projection on elastic card claw 2 by the cooperation voussoir 4 that its inwall is arranged, to control the degree that elastic card claw 2 actuates, and stop workpiece 5 that opening of rear elastic card claw 2 is installed, thus reach the clamping level strengthening elastic card claw 2 pairs of bow members, the effect of fastening elastic card claw 2 position.
In the above-described embodiments, coordinate with the fastener stoping card-tight part to expand outwardly for lock sleeve with elastic card claw is radial spacing, in other embodiments, lock sleeve also can replace with clip, wire loop or tight loop etc., namely in use, can by being wound around linear fastener to reach to the radial spacing object of elastic card claw around elastic card claw.
In the above-described embodiments, elastic card claw has two, and be semi-circular cylindrical elastic card claw, in other embodiments, elastic card claw also can be shaft-like or V-type or hook-shaped elastic card claw, the quantity of corresponding elastic card claw also can more than two, but when elastic card claw quantity is two, two elastic card claws must be symmetricly set on clamp body; When elastic card claw is three, elastic card claw must along the circumferential direction be evenly distributed on clamp body.
In the above-described embodiments, adhesive face is the adhesive plane coordinated with the datum plane face of sucker, but the datum level of sucker be sphere curved surface or arc-shaped curved surface time, adhesive plane coordinates the cooperation area that can not make sucker and clamp body to be maximum with the datum level of sucker, namely reduce the active force of sucker to clamp body, therefore in other embodiments, this adhesive face also can be sphere curved surface or arc-shaped curved surface etc.
In the above-described embodiments, the workpiece that the present invention is applicable to clamp is optical lens, and in other embodiments, it is block that the present invention is also applicable to clamping, tabular or plate-like workpiece.
In the above-described embodiments, elastic card claw is wholely set on clamp body, and in other embodiments, elastic card claw also can be fixed on clamp body by modes such as welding, bolt connection, buckle connections, these belong to the usual technological means of art technology person, therefore repeat no more.
