Abstract
The utility model relates to a mini-size drive device, in particular to a mini-size coupling which is applicable for a drive between an axis on the mini-size electromotor and a driven machine. The mini-size coupling firstly grinds the internal diameter of a section of steel tube with a thick wall to 0.1mm-0.2mm smaller than the corresponding axis diameter, then makes an outer screw and arranges two nuts, and then saws off 1-2 vertical gaps on the two ends of the screw steel tube respectively. When in use, the two nuts are screwed at the middle of the screw steel tube, the two axes are inserted in holes at the two ends of the steel tube (the vertical gaps on the steel tubes are slightly open), the two nuts are screwed toward the two ends, the steel tube is replaced under the pressure of the nuts, and thus the two axes are locked. The utility model has easy operation and solid connection. The utility model has the advantages of that the mini-size drive device can guarantee the coaxiality of the two axes, is unlikely to distortion after many times of assembly and disassembly, and is lasting and durable; besides, the utility model can guarantee utilization when the distance between then two axes are not accurate and changes the normal situation that the min-size coupling is easy to loose and be damaged.
Description
Technical field: the utility model is a kind of Miniactuator, is applicable to the between centers transmission of micro motor and institute's driving device.
Background technique: current, large and medium-sized shaft joint technology mechanically is very ripe, but when micromachine needs connecting shaft, adopt sleeves to add pin to fix or adopt the plastic sleeve of interference fit to connect more, sleeve add pin easily loosening and be difficult for guaranteeing diaxon with one heart, and plastic sleeve as long as dismounting one twice will can't use greatly because of the sleeve aperture becomes.
Summary of the invention: for overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of small-sized shaft joint, this small-sized shaft joint can not only be connected firmly the diaxon of micro motor and institute driving device guaranteeing under the concentric prerequisite, and repeatedly dismounting is indeformable, and is durable in use.
The technological scheme that its technical problem that solves the utility model adopts is: select one section thick walled steel tube, earlier steel tube inner hole is milled to the little 0.1-0.2 millimeter of the diameter of axle that cooperates than with it, do outside thread, mix two nuts, and two nuts are threaded in the middle of the steel pipe, again one to two perps is respectively cut with miniature saw blade in the threaded steel pipe two ends, the diaxon that needs are connected inserts in the hole at steel pipe two ends, (perps at two ends can be supportted open slightly), two nuts are rotated to two ends respectively, the pressure of nut forces steel pipe to reset, and diaxon promptly is locked.
The beneficial effects of the utility model are: easy to operate, link firmly, and can guarantee the concentric of diaxon, repeatedly dismounting is indeformable, and is durable in use, and also can guarantee to use when the distance of two between centers is not really accurate.
Description of drawings: accompanying drawing is a schematic representation of the present utility model.
1. make externally threaded steel pipe among the figure, 2. perps, 3. nut.
Embodiment: in the accompanying drawings, on doing on the externally threaded steel pipe (1), in the middle of two nuts (3) are threaded to, when the diaxon that needs are cooperated inserts in the hole at two ends, the perps of doing on the externally threaded steel pipe (1) (2) opens slightly, at this moment with two nuts (3) rotation direction two ends respectively, the pressure of nut (3) forces to be made externally threaded steel pipe (1) and resets, and diaxon is locked.
Claims (1)
- A kind of small-sized shaft joint, by grinding out suitable endoporus, do outside thread, and the thick walled steel tube that cracks at two ends, mix two nuts and form, it is characterized in that: the internal diameter of steel pipe is than the little 0.1-0.2 millimeter of the diameter of axle that cooperates with it, and 1-2 bar perps is respectively cut at the two ends of steel pipe.
