After using technique scheme, this utility model has the advantages that employing turns to compared to existing technology
The expansion hose of circle clamps workpiece in circle, by the expanding radial force of circle by Workpiece clamping, owing to expansion hose has necessarily
Expansive force, thus there is certain workpiece buffering overdose space diametrically, do not result in rapid wear workpiece because of prominent come clamping
Power and impaired or deformation；Using flexible pipe maintaining part to be supported expansion hose, it is many that supporting walls is possible to prevent expansion hose to expand
Degree, and keep the shape of expansion hose lopping, expansion hose is fastened between supporting walls and rapid wear workpiece, thus clamps rapid wear
Workpiece, connecting portion can be used to realize the connection of clamping device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the clamping device of the workpiece of this utility model one embodiment.
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 above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The detailed description of the invention of utility model is described in detail.
Elaborate a lot of detail in the following description so that fully understanding this utility model.But this practicality is new
Type can be implemented to be much different from alternate manner described here, and those skilled in the art can be new without prejudice to this practicality
Doing similar popularization in the case of type intension, therefore this utility model 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 exist
Clamping process damages or deforms.Rapid wear workpiece refers to that intensity is weak, poor rigidity, in clamping process easily because chucking power is excessive
The workpiece of damaged deformation.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 expansion hose 1 to be coiled into
The expansive force of circle clamps workpiece 10, and expansive force, by rapid wear workpiece swelling, makes the soft support of each point of workpiece 10 held position, no
Fragile or deformation.Flexible pipe maintaining part 2 has supporting walls, arranges the expansion hose 1 of this coiling lopping, supporting walls inside supporting walls
Expansion hose 1 superdistension can be limited, keep the one-tenth loop-shaped of expansion hose 1, expansion hose 1 is played a supporting role.Connect
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 dress
Put, by fixing device fixed clamp device, thus stablizing of clamping device can be kept in the course of processing.
Preferably, expansion hose 1 coiling multi-turn is arranged on inside supporting walls, and the inner side of each circle directly contacts workpiece, outer
Side directly contacts supporting walls, say, that expansion hose 1 along supporting walls coiling lopping, each circle on the axial direction of circle side by side
Arrangement, 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, can be in the external world
It is made to produce expansion under the influence of factor, such as temperature, gas pressure etc.；Expansion hose 1 can also be self to have expanded tool
There is the flexible pipe of certain pliability, be arranged on inside supporting walls.
In one embodiment, expansion hose 1 is inflated hose, and after inner inflatable, inflated hose expands with by the work in circle
Part 10 clamps.Adding 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 can be adjusted according to the rapid wear degree of the rapid wear workpiece of unlike material
And aeration quantity, 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, and filling object 4 is the most inaccessible
Bolt, 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, should
One end is plugged.Certainly inflated hose can also be that two ends are unimpeded, is produced lasting inflation by the inflation of persistent loop
Pressure, makes inflated hose remain inflated for.
In one embodiment, clamping device can also include aerating device (not shown).The inflation of aerating device
Mouth connects this other end of the gas turnover of inflated hose, is inflated in inflated hose.The aeration quantity of aerating device and filling
Atmospheric pressure is adjustable.
The other end of inflated hose (expansion hose 1) can be provided with hard short tube 5, as the turnover gas of inflated hose
Mouthful, 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 big
In semi arch.Inflated hose can be made farthest to fit with supporting walls.Highly preferred being more than or equal to of supporting walls turns to
The height of the expansion hose of circle, so that inflated hose is preferably supported, the beneficially regulation and control of workpiece clamp clamp force.
Although this utility model is open as above with preferred embodiment, but it is not for limiting claim, Ren Heben
Skilled person, without departing from spirit and scope of the present utility model, can make possible variation and amendment, therefore
Protection domain of the present utility model should be defined in the range of standard with this utility model claim.
