Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
In this application unless specifically defined or limited otherwise, term " fixation ", " connection " shall be understood in a broad sense, example
Such as, it may be a fixed connection, may be a detachable connection, or is integral；It can be mechanical connection, can also be electrical connection；
It can be directly connected, can also can be indirectly connected through an intermediary the connection inside two elements or two elements
Interaction relationship.For the ordinary skill in the art, above-mentioned term can be understood at this as the case may be
Concrete meaning in invention.
As shown in Figs. 1-2, a kind of thin-wall pipe clamp for machining includes scroll chuck, and the scroll chuck includes chuck body
10 and three claws 20 in chuck body 10, the peripheral surface of each claw 20 be fixedly installed an elastic balloon
30, three elastic balloons 30 are connected to by a tracheae 508 with an aerating and exhaust device 50 respectively, and elastic balloon 30 has bullet
Property, it can fully be expanded after ensure that its inflation.When work, first claw 20 is used to press from both sides the inner wall of thin-wall pipe 70 first
Tightly, clamping force should not be too large, and then be inflated into three elastic balloons 30 by aerating and exhaust device 50, due to elastic balloon 30
Side is connect with the peripheral surface of claw 20, therefore the direction of another peripheral surface for being laterally away from claw 20 of elastic balloon 30 is swollen
It is swollen, to push up the section tubular wall of the thin-wall pipe 70 of the peripheral surface institute face of claw 20 outward, to which 30 one side of air bag is supported
When the claw 20 that disappeared clamps thin-wall pipe 70 to the deformation on the direction of 20 peripheral surface of claw, on the other hand the part is closed
The contact area with the inner wall of thin-wall pipe 70 is increased again so that the more difficult of thin-wall pipe 70 deforms, Jin Eryou
Effect ground solves the problems, such as to be easy to cause the deformation of thin-wall pipe 70 when clamping thin-wall pipe 70.
As being further improved for said program, the aerating and exhaust device 50 includes the cylinder that one end has an interconnecting piece 502
Body 501, the piston 503 being arranged in the cylinder 501, one end is connect with the piston 503, the other end extend out to cylinder 501
The other end outside piston rod 504 and the nut 505 in the other end of the cylinder 501, the interconnecting piece 502 are set
It is connect with a four-way 507, other three connectors of four-way 507 are connect with a tracheae 508 respectively, and the piston rod 504 passes through institute
State nut 505 and with 505 screw-thread fit of the nut.Being equipped in the end of the other end of piston rod 504 facilitates rotation to live
The handle 506 of stopper rod 504.In use, by rotational handle 506, piston rod 504 is set to rotate, due to piston rod 504 and nut
505 screw-thread fits, thus in 504 rotation process of piston rod can also with piston 503 in cylinder 501 precession or rotation move back, to
Realize inflation/deflation.Screw thread pair between piston rod 504 and nut 505 also acts the effect of locking, can make piston 503 in this way
Any position being maintained in cylinder 501.Preferably, the aerating and exhaust device 50 is fixed on the card by a fixing device
On disk ontology 10, the fixing device include the screw rod 601 that one end is threadedly coupled with chuck body 10 and with the screw rod 601
The clip 602 that is fixedly connected of the other end, cylinder 501 is fixed by clip 602, and by screw rod 601 by entire inflation/deflation
Device 50 is fixed in chuck body 10, and above-mentioned fixture structure is simple, easy to use, and being between chuck body 10 can
Dismantling connection can be removed easily from chuck body 10 when without processing thin-wall pipe 70.
As being further improved for said program, the elastic balloon 30 passes through the outer of a connection piece 40 and the claw 20
Circumferential surface is detachably connected.It, can be easily by elastic balloon 30 from chuck body 10 in this way when without processing thin-wall pipe 70
On remove, make scroll chuck for clamping other workpiece.
As being further improved for said program, the connector 40 includes body part 401 and one end and the body part
401 connections, the other end are inserted into the bolt 402 being clamped in claw 20 and with claw 20, and being provided on claw 20 makes bolt 402 be inserted into
Pin hole 201, the pin hole 201 be through-hole, convenient for exiting bolt 402 from pin hole 201.Described one end of bolt 402 and sheet
401 integrally connected of body portion.In the present embodiment, bolt 402 is interference fitted with pin hole 201, to realize bolt 402 and claw 20
Clamping.Above-mentioned connector 40 is simple in structure, easy to use.
As being further improved for said program, the peripheral surface of the claw 20 is a flat surface, and the peripheral surface is provided with one
The groove 202 for making the body part 401 be embedded in.Overall structure is simpler and body part 401 will not occupy 20 periphery of claw
Space between face and the tube wall of thin-wall pipe 70.
As being further improved for said program, the cross-sectional shape of the elastic balloon 30 is D-shaped, and such air bag 30 fills
It can bigger with the contact area of the tube wall of thin-wall pipe 70 after gas expansion.
