According to one embodiment of present invention, also including aerating device, its inflation inlet connects the other end of described inflated hose, in order to be inflated in described inflated hose.
According to one embodiment of present invention, the other end of described inflated hose is provided with hard short tube, as the air inlet/outlet of inflated hose.
According to one embodiment of present invention, described inflated hose is oil resistant air hose.
According to one embodiment of present invention, described supporting walls is annulus wall or a part for annulus wall, and the cross section arc of a part for described annulus wall is more than semi arch.
According to one embodiment of present invention, the height of described supporting walls is more than or equal to the height of the expansion hose of described coiling lopping.
According to one embodiment of present invention, described connecting portion one end is fixing connects described flexible pipe maintaining part, and the other end is connected to fixing device.
After using technique scheme, the present invention has the advantages that the expansion hose using coiling lopping clamps workpiece in circle compared to existing technology, by the expanding radial force of circle by Workpiece clamping, owing to expansion hose has certain expansive force, thus there is certain workpiece buffering overdose space diametrically, do not result in the impaired or deformation because of prominent next chucking power of rapid wear workpiece；Use flexible pipe maintaining part that expansion hose is supported, supporting walls is possible to prevent expansion hose to expand spend more, and keeps the shape of expansion hose lopping, and expansion hose is fastened between supporting walls and rapid wear workpiece, thus clamping rapid wear workpiece, connecting portion can be used to realize the connection of clamping device.

Fig. 1 is the structural representation of the clamping device of the workpiece of one embodiment of the invention.
Description of symbols in figure:
1-expansion hose, 2-flexible pipe maintaining part, 3-connecting portion, 4-clogs object, 5-hard short tube, 10-workpiece.
Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
Elaborate a lot of detail in the following description so that fully understanding the present invention.But the present invention can implement to be much different from alternate manner described here, those skilled in the art can do similar popularization in the case of intension of the present invention, and therefore the present invention is not limited by following public being embodied as.
Referring to Fig. 1, the clamping device of the workpiece of the present embodiment, workpiece 10 can in a tubular form or cylindric, and this device includes: expansion hose 1, flexible pipe maintaining part 2 and connecting portion 3.Clamping device can be used to clamp rapid wear workpiece, is difficult to make rapid wear workpiece damage in clamping process or deform.Rapid wear workpiece refers to that intensity is weak, poor rigidity, in clamping process easily because of the workpiece of the excessive and damaged deformation of chucking power.It can be such as the thin-wall workpiece of material rapid wear.
Wherein, expansion hose 1 coiling lopping, for clamping workpiece 10 in the circle being coiled into, utilize the expansive force of the circle that expansion hose 1 is coiled into clamp workpiece 10, expansive force, by rapid wear workpiece swelling, makes the soft support of each point of workpiece 10 held position, is hardly damaged or deforms.Flexible pipe maintaining part 2 has supporting walls, arranges the expansion hose 1 of this coiling lopping inside supporting walls, and supporting walls can limit expansion hose 1 superdistension, keeps the one-tenth loop-shaped of expansion hose 1, plays a supporting role expansion hose 1.Connecting portion 3 is connected in flexible pipe maintaining part 2, and the installation being used for realizing whole clamping device connects.
Optionally, one end of connecting portion 3 is fixing connects flexible pipe maintaining part 2, and the other end of connecting portion 3 is connected to fixing device, by fixing device fixed clamp device, thus can keep stablizing of clamping device in the course of processing.
Preferably, expansion hose 1 coiling multi-turn is arranged on inside supporting walls, the inner side of each circle directly contacts workpiece, outside and directly contacts supporting walls, that is, expansion hose 1 is along supporting walls coiling lopping, each circle is arranged side by side on the axial direction of circle, utilizes expansion hose 1 at the most homogeneous expansive force of circle to support workpiece 10, makes workpiece 10 each point uniform force.
Expansion hose 1 can be arbitrarily to expand and have upon inflation the flexible pipe of certain pliability, it can be made to produce expansion, such as temperature, gas pressure etc. under the influence of extraneous factor；Expansion hose 1 can also be the flexible pipe self having expanded and having had certain pliability, is arranged on inside supporting walls.
In one embodiment, expansion hose 1 is inflated hose, and after inner inflatable, inflated hose expands to clamp the workpiece 10 in circle.Add air realize the expansion of inflated hose by filling in inflated hose, swell increment is determined by the pressure inflated, and aeration quantity and the blowing pressure adjustable, thus the blowing pressure and aeration quantity can be adjusted according to the rapid wear degree of the rapid wear workpiece of unlike material, the swelling degree of regulation inflated hose, thus it is adjusted to suitable chucking power.
Concrete, inflated hose can be oil resistant air hose, realizes the expansion of sebific duct by being inwardly filled with air.
Optionally, one end of inflated hose is provided with the filling object 4 in order to this end of blocking, clogs object 4 e.g. block plug, and the other end of inflated hose passes in and out in order to gas, say, that this other end at inflated hose is inflated losing heart, and this one end is plugged.Certainly inflated hose can also be that two ends are unimpeded, is produced lasting the blowing pressure by the inflation of persistent loop, makes inflated hose remain inflated for.
In one embodiment, clamping device can also include aerating device (not shown).The inflation inlet of aerating device connects this other end of the gas turnover of inflated hose, is inflated in inflated hose.Aeration quantity and the blowing pressure of aerating device are adjustable.
The other end of inflated hose (expansion hose 1) can be provided with hard short tube 5, as the air inlet/outlet of inflated hose, it is simple to the connection of inflation.
It is also preferred that the left supporting walls is annulus wall or a part for annulus wall, the cross section arc of a part for annulus wall is more than semi arch.Inflated hose can be made farthest to fit with supporting walls.The height of the highly preferred expansion hose more than or equal to coiling lopping of supporting walls, so that inflated hose is preferably supported, the beneficially regulation and control of workpiece clamp clamp force.
Although the present invention is open as above with preferred embodiment; but it is not for limiting claim; any those skilled in the art are without departing from the spirit and scope of the present invention; can make possible variation and amendment, therefore protection scope of the present invention should be defined in the range of standard with the claims in the present invention.
