Description
Technical field
The utility model relates to a kind of accessory of electric tool, especially relates to a kind of fast assembling and disassembling device of clamping electric tool tool heads.
Background technology
For the electric tool that rotates, because of will often changing working head, so require quick loading and unloading head.The simplest fast handler is to be provided with convex tendon in working head diameter of axle both sides, directly is plugged in the corresponding hole of electric tool output sleeve, drives working head work by power.Though this structure is simple in structure, because the power output can not clamp working head, regular meeting working head occurs and comes off, and causes functional reliability to descend.The fast assembling and disassembling device of another kind of structure is to come the clamping working head by the inclination intermediate plate that is arranged in the power output shaft cover, but the quick-release apparatus structure complexity of this structure, install and remove cumbersome, especially to the requirement on machining accuracy height of intermediate plate, the manufacturing cost height.
Goal of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to loading and unloading, be convenient to make, fast assembling and disassembling device that processing cost is low.
The further purpose of the utility model provides a kind of fast assembling and disassembling device of long service life.
The utility model is that the technical scheme that achieves the above object is: a kind of fast assembling and disassembling device, it is characterized in that: comprise the power output shaft cover that has internal keyway and be fixed on the connecting bushing that power output shaft overlaps a side, big outer little taper hole in the front portion of connecting bushing has, make the movable axle sleeve one side of axially-movable outside connecting bushing along the connecting bushing endoporus, spring is arranged between the inner face of power output shaft cover and connecting bushing, the radially installing hole that is positioned at the movable axle sleeve of connecting bushing is equipped with rolling element, hole wall along taper hole when rolling element moves axially with the movable axis interplanting moves radially, the rolling element when working shaft and power output shaft cover is connected respectively with taper hole and working shaft clamping.
The utility model is that the technical scheme that reaches above-mentioned further purpose is: the installing hole of described movable axle sleeve is a taper hole.
The utility model adopts the advantage after the technique scheme to be: the utility model only is provided with taper hole in the front portion of connecting bushing, and match with rolling element in the radially installing hole of movable axle sleeve, be enclosed within when moving axially in the connecting bushing by movable axis, and the radial position of change rolling element, can the conveniently assemble and disassemble working shaft, can clamp working shaft by the contact point of rolling element again, it is simple in structure, install and remove very convenient, and the inclined-plane of the taper hole of connecting bushing reliable clamping working shaft not only, and the diameter of rolling element clamping working shaft can also be adjusted in this inclined-plane, therefore need not be with higher processing precision and installation accuracy to connecting bushing and movable axis, be convenient to processing, manufacturing cost is lower.Moreover,, can also continue to clamp working shaft after remedying the wearing and tearing of rolling element by the automatic aligning effect of taper hole because of the radially installing hole of rolling element adopts the taper hole structure, can effectively improve the working life of fast handler.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Fast assembling and disassembling device as shown in Figure 1, have the power output shaft cover 1, connecting bushing 2 and the movable axle sleeve 5 that have internal keyway, connecting bushing 2 is fixed on the power output shaft cover 1, and big outer little taper hole 2-1 in the front portion of connecting bushing 2 has, one side of movable axle sleeve 5 is contained in the connecting bushing 2 and is positioned at taper hole 2-1 place, the opposite side of movable axle sleeve 5 places outside the connecting bushing 2, movable axle sleeve 5 moves axially along the endoporus of connecting bushing 2, spring 3 is arranged between the inner face of power output shaft cover 1 and connecting bushing 2, works to hold out against movable axis cover 5 and resets.The movable axle sleeve 5 that is positioned at connecting bushing 2 has radially installing hole 5-1, radially in the installing hole 5-1 rolling element 4 is housed, when rolling element 4 moves axially with movable axle sleeve 5, taper hole 2-1 hole wall along connecting bushing 2 moves radially, in the time of in working shaft 7 is installed in power output shaft cover 1, then rolling element 4 respectively with the taper hole 2-1 and working shaft 7 clampings of connecting bushing 2.
Be to prolong the service life of fast assembling and disassembling device, the radially installing hole 5-1 of movable axle sleeve 5 is a taper hole, and radially installing hole one or more be distributed on the movable axle sleeve 5.
For the ease of moving of movable axle sleeve 5, the outside of movable axle sleeve 5 is provided with push pedal 6, and movable axle sleeve 5 can be structure as a whole with push pedal 6 or divide body structure.
At installment work axle 7, promotion activity axle sleeve 5 moves inwards, and rolling element 4 moves radially along the hole wall of connecting bushing 2 taper hole 2-1, and the clamping diameter of rolling element 4 is increased; After working shaft 7 and power output shaft overlap keyway engagement in 1 axis hole, under the effect of spring 3 elastic force, movable axle sleeve 5 outwards moves, and rolling element 4 is still under the effect of taper hole 2-1, the clamping diameter diminishes, and makes rolling element 4 be connected to the hole wall place of working shaft 7 and taper hole 5-1 at last.When dismantlement work axle 7, promotion activity axle sleeve 5 moves inwards, and same, rolling element 4 moves radially along the hole wall of taper hole 2-1, and it is big that the clamping diameter of rolling element 4 becomes, and working shaft 7 promptly then can be deviate from.Outside when mobile when working shaft 7, then the clamping diameter of rolling element 4 is more little, and clamping working shaft 7 is just tight more, and operation is very easy, reliable.
