Background technology
Along with the use of power hand tool is more and more extensive, the single and non-exchange power hand tool of attachment can not adapt to the higher requirement that people propose versatility, autgmentability and convenience.
When reality uses, often need the expansion by installing different attachments thus practical function to a power hand tool, can realize on the basis to effective transmission of attachment, the chuck mechanism that can effectively clamp and realize faster replacing becomes the key of practical function versatility, autgmentability and convenience.
Traditional chuck mechanism, although can the installation of effective implementation tool annex, when erecting tools annex, often need both hands to operate chuck mechanism and attachment simultaneously, this is very inconvenient in actual use, because operator often singlehandedly can only hold power hand tool.Still there is no a kind of chuck mechanism that can be realized automatic tool exchange annex by user's one-handed performance now.
Summary of the invention
In order to solve the deficiencies in the prior art, the object of the present invention is to provide a kind of chuck mechanism that can be realized automatic tool exchange annex by user's one-handed performance; Its replacing that can make attachment is more quick, simplifies the action that user changes attachment, ensures operating efficiency while reducing labour intensity, thus achieves the function versatility of power hand tool, autgmentability and convenience.
To achieve these goals, the present invention adopts following technical scheme:
First, in order to realize effective clamping of attachment and the space providing accommodation, the chuck mechanism of automatic tool exchange annex of the present invention comprises: output shaft, sleeve pipe and keeper.
Wherein the Main Function of output shaft is to hold attachment, output shaft is provided with a cavity volume, enable attachment by being moved in the cavity volume of output shaft, certainly the cavity volume of output shaft can also be skidded off, in other words, output shaft can skid off displacement except direction by Limit Tool annex except attachment slips into.Concrete shape and the design of the cavity volume of output shaft and inside thereof can be determined according to concrete attachment.The cavity volume of output shaft and output shaft inside can adopt rotary structure, and this structure is suitable for the power hand tool of this kind of rotation class of electric screwdriver.Certainly, in order to adapt to other attachment, the cross sectional shape of the cavity volume of output shaft and output shaft inside also can be regular hexagon, square etc.
The effect of sleeve pipe and keeper is to block the attachment in output shaft cavity volume, and as previously mentioned, their main Limit Tool annexes slip into the displacement skidding off and direction produces in output shaft, reach the effect clamping attachment.Sleeve pipe is arranged at the periphery of output shaft one end, and can relatively move by output shaft, and it is consistent that the direction of motion and attachment slide into the direction skidding off output shaft.
The sidewall of output shaft cavity volume is provided with for holding keeper and making a part for keeper enter into the locating hole of output shaft cavity volume, that is locating hole is out that on output shaft sidewall one is for placement positioning part and the hole through with output shaft cavity volume, when keeper is when being subject to certain extruding, the part of keeper can enter in output shaft and contacts with attachment thus limit the position of attachment, the number of locating hole, distribution, the shape (number of keeper should match with locating hole number) of shape and keeper can design according to the attachment of concrete application, generally speaking, at least one group of locating hole should be formed in the circumferential direction of output shaft, for the consideration of fixing stability, locating hole should be uniformly distributed in circumferential direction, if for the consideration strengthening clamping reliability, the length direction of output shaft arranges the locating hole of several groups of circumference distributions more, the corresponding construction of the corresponding sleeve pipe introduced below also correspondingly should make increase, this point is self-evident, do not repeat at this.
It should be noted that, sleeve pipe is formed and covers locating hole periphery for extruding or loosen the multistage inwall of keeper, in other words, namely the inwall of sleeve pipe is not uniformity, to make it when with output shaft relative sliding, space between internal surface of sleeve pipe face and locating hole is made to be change, so, internal surface of sleeve pipe is when the space formed with locating hole is less, namely during internal surface of sleeve pipe extruding keeper, keeper due to space less, its considerable part enters into output shaft cavity volume by locating hole, enter this quite a few can coordinate with the location structure of attachment and block attachment, realize clamping, this state be also sleeve pipe general time state, namely state when clamping or zero load, be referred to as general state temporarily, when internal surface of sleeve pipe is when the space formed with locating hole is larger, namely when internal surface of sleeve pipe is in relaxation state non-contacting with keeper, keeper due to space larger, be not in locating hole or only have a little part to be arranged in output shaft cavity volume by locating hole, that no longer hinders attachment skids off or is not enough to skidding off of obstruction attachment, this state is for slipping into the state skidded off required for that appointment short time when installing or unload, the state of namely installing or unloading, is referred to as intermittent condition temporarily.
But need clear and definite being a bit herein; the size and dimension of locating hole should be suitable; keeper is made to be unlikely to enter into output shaft cavity volume completely by locating hole completely; the switching of above-mentioned two states cannot be realized again; this point is that persons skilled in the art should be expected without creative work when designing; illustrate to be only at this and avert misconceptions, but should as limiting the scope of the invention.
As fully visible, if can be realized the automatic switchover of above-mentioned two states by an action, the automatic clamp installation and dismantling of implementation tool annex are unloaded, and this is also major part of the present invention.
In order to realize the automatic switchover being completed above-mentioned two states by an action, the chuck mechanism of automatic tool exchange annex of the present invention also includes: attract part and reset assembly.
As previously mentioned, the prerequisite of two state switchings is exactly the relative motion of sleeve pipe and output shaft, once relative motion occurs, namely general state stops, relative motion occurs to and to a certain degree namely there will be aforementioned intermittent condition, therefore in design philosophy of the present invention, relative motion state being switched middle sleeve and output shaft uniquely needs as user the action done, namely trigger action, after user is as this action, attachment just should exit output shaft, and the SBR (with state consistency during clamping) of replying as loading new attachment next time.Other action needs by attracting part and reset assembly to be achieved.
Wherein, part is attracted to be fixedly connected with output shaft, it is close thus enter locating hole to it that its Main Function is to attract keeper, through with output shaft cavity volume, its object is to attract part that keeper can be made can be returned in above-mentioned general state in state (under the state that namely internal surface of sleeve pipe does not extrude it) freely, attracting part why to be fixedly connected with output shaft, is because locating hole is certain relative to the position of output shaft, and the target that locating hole attracts part attraction keeper to enter just.Had attraction part, keeper can reply general state when not having external operation.
