For achieving the above object, the technical solution used in the present invention is: a kind of thin-wall circular tube turning clamping device, comprise for the inclined plane slide block that is slidably installed slider bracket, for being slidably installed and supporting the screw rod of tapered sleeve and the gripping base for driving described slider bracket and described screw rod to rotate with lathe spindle, it is characterized in that: also comprise the inclined plane slide block and tapered sleeve with identical tapering, described slider bracket and described screw rod are all fixedly mounted on described gripping base one end, described screw rod is slidably fitted with tapered sleeve, described slider bracket is provided with at least two installation chutes be uniformly distributed around described screw rod axle center for installing described inclined plane slide block, all being slidably fitted with in each described installation chute matches for the inclined plane slide block from medial roof clamping of workpieces with described tapered sleeve, elastic cushion block is provided with between each described inclined plane slide block and described workpiece, described screw rod end is provided with the clamp nut for compressing described tapered sleeve, improved mat is provided with between described clamp nut and described tapered sleeve end face, back-moving spring is provided with between described tapered sleeve and described gripping base.
Above-mentioned thin-wall circular tube turning clamping device, is characterized in that: described slider bracket is fixedly mounted on described gripping base by described trip bolt, and described screw rod is welded or is fixedly mounted on described gripping base by screw thread.
Above-mentioned thin-wall circular tube turning clamping device, is characterized in that: described elastic cushion block is rubber cushion blocks.
The present invention compared with prior art has the following advantages:
(1) design of this thin-wall circular tube turning clamping device is very reasonable, and simple and compact for structure, slide block and tapered sleeve hold out against workpiece to be machined with the use of from inside, and result of use is good, and Workpiece Machining Accuracy is high.
(2) the workpiece easy accessibility of this thin-wall circular tube turning clamping device, operating personnel only need use spanner to rotate clamp nut and can compress or unclamp workpiece to be machined, and thus labor strength is low, and production efficiency is high, are applicable to processing in enormous quantities.
(3) a lot of parts of this thin-wall circular tube turning clamping device are convenient to produce, buy all very much, and thus its production cost is very low, is convenient to batch production, promotes the use of.
Below by drawings and Examples, the present invention is described in further detail.
