【Embodiment】
The utilization magnetic field repulses power to the embodiment of the present invention realizes the submissive buffer gear of peg-in-hole assembly below in conjunction with the accompanying drawings
It is described in detail.
The present invention is the submissive buffer gear that a kind of utilization magnetic field repulses power realizes peg-in-hole assembly, including housing 1, the shell
The inner upper of body 1 is provided with the first magnet 14, and the lower inside of housing 1 is arranged with can be relative to first magnet about 14
Mobile adjustment direction and the submissive connection member 2 for realizing peg-in-hole assembly, the submissive connection member 2 include at least being used for
Axle realizes connection and stretches out the end connectors 23 of the housing 1, and the upper end of the end connectors 23 is provided with and described first
Magnet 14 has cushion space with the second opposite magnet 21 of magnetic pole between first magnet 14 and second magnet 21
(15)。
Specifically, the housing 1 includes upper cover plate 11 and lower cover 12, between the upper cover plate 11 and the lower cover 12
Provided with protective sleeve 13.Its is simple in construction, convenient processing and manufacture and cheap.
Further, the guiding insertion for guiding is additionally provided between second magnet 21 and the end connectors 23
Part 22.The advantage is that the guiding insert 22 can be rapidly its guiding of end connectors 23 direction.
Further, the lower cover 12 includes the first lower cover 121 and the second lower cover 122, first lower cover
121 are provided with the taper guide hole 1211 for being used for coordinating with the guiding insert 22, and second lower cover 122, which is provided with, to be used for
The housing 1 is stretched out for the end connectors 23 and more than the through hole 1221 of the end connectors 23.The lower cover 12
It is to make its processing and manufacturing that easier, Jin Erke is installed in the case where disclosure satisfy that job requirement using the purpose of combining structure
To reduce financial cost.
Further, the aperture of the through hole 1221 is less than the aperture of the taper guide hole 1211.So described second
Lower cover 122 plays a position-limiting action for the submissive connection member 2.
Further, first magnet 14 and second magnet 21 are cylinder, and first magnet 14
Diameter be more than second magnet 21.Its advantage be can for the submissive connection member 2 inside the housing 1 relative to
Arbitrary region when first magnet 14 moves up and down adjustment direction can provide its magnetic field repulses power, meet peg-in-hole assembly
Requirements of one's work.
Further, first magnet 14 and second magnet 21 are made by rare-earth permanent magnet.Using rare earth
Permanent magnet is, because its rare-earth permanent magnet has permanent magnetism, not changed the permanent of itself by extraneous factor.
Further, the protective sleeve 13 is preferably that lucite is made.The protective jacket is made using lucite
Cylinder 13 be because：One lucite is pellucidity, constantly the action performed by the mechanism can be monitored, its divalence
Lattice are cheap, thirdly being detrimental to health without the fragility of conventional clear glass.
The present invention realizes the method that the submissive buffer gear of peg-in-hole assembly performs peg-in-hole assembly using magnetic field repulses power：
Workpiece provided with the hole for peg-in-hole assembly is positioned over to the underface of submissive buffer gear, submissive buffer gear leads to
Cross the end connectors 23 connection axial workpiece hole position be installed and move from top to bottom, when installation axle contacted with hole and by jam
When, installation axle relative to hole axial run-off the straight (referring to Fig. 8 and Fig. 9), while installation axle because by jam by its jam
Reaction, forces installation axle to be raised above together with the submissive connection member 2 relative to first magnet 14, i.e., and described
Two magnets 21 move closer to first magnet 14, and magnetic field repulses power gradually increases therewith, and then buffer the reaction of its impedance,
When the counteractive reaction force of magnetic field big excessively its impedance of wiping repulsive force, its described submissive connection member 2 exists together with installation axle
Wipe that repulsive force effect is lower to carry out position adjustment in magnetic field so that installation axle is correctly aligned with hole, and in magnetic field repulses power and external force
Promote installation axle to move down under collective effect, complete peg-in-hole assembly work.
Embodiments of the present invention are explained in detail in summary, but the invention is not restricted to above-mentioned embodiment.
Even if it is to the present invention, various changes can be made, then still fall within protection scope of the present invention.
