Annular thin-wall article clamping device and using method thereof

Abstract

The invention provides an annular thin-wall article clamping device and a using method of the device. The clamping device comprises an annular chassis; the chassis is provided with a radial regulation mechanism of a locating workpiece; the radial regulation mechanism is divided into an inner radial regulation mechanism and an outer radial mechanism; two radial regulation mechanisms position workpiece respectively from the inner side or the outer side of the workpiece; the chassis is respectively provided with track-directed sliding grooves for the two radial adjustment mechanisms; the inner end of the sliding groove of the inner radial regulation mechanism is provided with a stopping block; the outer end of the sliding groove of the outer radial regulation mechanism is provided with the stopping block; the sliding grooves of the two groups of radial regulation mechanisms are disposed at intervals; one of the two groups of radial regulation mechanisms is provided with an axial compacting mechanism for fixing the workpiece; and the axial compacting mechanism is displaced alternatively between the two groups of radial regulation mechanisms when turning the workpiece. The clamping device can realize the processing of two side walls of the workpiece by clamping the workpiece once, and is fit for the clamping of the workpieces with different specifications. The device has the characteristics of high use rate, strong practical applicability, good generality, time saving and labor saving, light labor intensity, high production efficiency and the like.

Description

Technical field: [0001] The invention relates to a clamping device for ring-shaped thin-walled parts, in particular to a clamping device for ring-shaped thin-walled parts and a method for using the device. It is especially suitable for turning and clamping of large annular thin-walled parts such as gas turbine shrouds, and can also be used for turning and clamping of other annular thin-walled parts. Background technique: [0002] Thin-walled parts have the characteristics of light weight, material saving, and compact structure, and have been widely used in industrial production. However, for a long time, thin-walled parts have been difficult to process in machining because of their poor rigidity and weak strength, they are easily deformed during processing, the processing quality is not easy to guarantee, and the product qualification rate is low. It is an annular thin-walled part. [0003] Annular thin-walled parts are usually processed by CNC turning, because of the diff...

Problems solved by technology

However, regardless of the mold clamping method or the traditional several clamping methods, they can only achieve one-time clamping and can only realize the processing of the wall surface on one side (inside or outside) of the workpiece, and the processing of the wall surface on the other side of the workpiece. have to be re-clamped, which will take a lot of time and affect the production efficiency of the enterprise

What's more, because of the re-clamping of several traditional clamping methods, it takes a lot of time to find the alignment and positioning accuracy of the workpiece. Even so, the positioning accuracy of the workpiece after re-clamping will be directly affected
