The important indicator whether energy Work machine is fully used, current replacing is all bolted, and replacing construction is long, institute
Need instrument many, high labor intensive, it is not easy to the popularization of small multifunctional working machine tool.In the feelings not affecting an operation part operating mode
The how quick-replaceable different work part problem that to be domestic miniature farm machinery expert endeavour to study under condition.
Utility model content
The purpose of this utility model be for existing small-size multifunction chassis change different work part in the presence of
The problems referred to above, and propose one kind and do not affect operation part operating mode and can be with quick-replaceable fast interface device.
The purpose of this utility model can be realized by following technical proposal：
A kind of Small Universal chassis fast interface device, it coordinate on the drive disk assembly of universal chassis it is characterised in that
It includes device overcoat, device inner sleeve, power-transmitting part and latch feature, and described device overcoat is coaxially filled with device inner sleeve
Join, and axially position is carried out by latch feature, power-transmitting part includes male splined shaft, female splined shaft, bearing, bearing sleeve
With bolt and spacer for bolt, latch feature includes bolt rod, spring, spring spool, back-up ring, latch pad and driving lever, outside device
Set is bolted on each operation part, and device inner sleeve is bolted on Small Universal chassis, when driving lever is fixed
During position, compression spring lifts bolt rod, and device overcoat is departed from device inner sleeve, and when driving lever playbacks, bolt rod passes through spring
Pin hole set by elastic force insertion apparatus inner sleeve, carries out both axially positions.
In a kind of above-mentioned Small Universal chassis fast interface device, described bearing and device inner sleeve interference fit,
Female splined shaft, male splined shaft and bearing three are coaxially disposed, and female splined shaft is bolted with male splined shaft, male splined shaft with
Bearing carries out axially position by bearing sleeve.
Compared with prior art, fast interface device in this Small Universal chassis can complete under not affecting operation part operating mode
The replacing of each operation part, greatly improves replacing efficiency, reduces labour intensity.
