Further, the hoop arc plates are symmetrically arranged at intervals, the height of the hoop arc plates is lower than that of the round thin-wall piece, and the groove is formed in the vertical downward direction.
Further, the one end of staple bolt arc bottom is the bull stick, is connected with the chassis pivot, and the other end is the fixture block, retaining member locking fixture block.
Further, the retaining member comprises a C-shaped block connected with the chassis rotating shaft, an action sleeve is arranged in the middle of the C-shaped block, and the C-shaped block is used for clamping the clamping blocks of the two hoop arc plates.
The beneficial effects of the utility model are as follows: according to the utility model, the circular thin-walled workpiece is pressed by the step pressing plate, the step pressing plate can also play a role in positioning the circular thin-walled workpiece, meanwhile, the circular thin-walled workpiece is fixed by the pair of opposite hoop arc plates, the hoop arc plates have a certain height, the contact area with the circular thin-walled workpiece is large, the clamping of the middle and upper parts of the workpiece can be realized, and the subsequent processing stability of the workpiece is facilitated.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.
As shown in fig. 1 and 2, the convenient clamping tool for the circular thin-walled workpiece provided by the embodiment comprises a chassis 1, a threaded column 2 is fixed at the axial center position of the chassis 1 upwards, a stepped pressing plate 3 is penetrated into the threaded column 2 and then screwed into a locking nut 4, the stepped pressing plate 3 is circular, the diameter of the lower layer is smaller than that of the upper layer, a pair of hoop arc plates 5 are piled on the chassis 1, one end of each hoop arc plate 5 is connected to the chassis 1 in a rotating shaft manner, and the other end of each hoop arc plate is locked through a locking piece.
In the structure, the bottom of the circular thin-wall part shown in fig. 3 is provided with a positioning plate, the middle of the positioning plate is provided with a round hole, and the side of the positioning plate is provided with a special-shaped hole. The chassis is mounted on a T-shaped groove of the processing equipment. The step clamp plate in this embodiment is circular, has upper and lower two-layer, and wherein lower floor diameter is less than upper strata diameter, and lower floor diameter and circular thin wall spare's bottom round hole aperture just match, place circular thin wall spare on the chassis after for the lower floor of step clamp plate can just in getting into the round hole through finely tuning circular thin wall spare, can realize the location to circular thin wall spare. The nut is then screwed in, in which case it does not need to be fully tightened. And then the hoop circular arc plates are closed, the two hoop circular arc plates can tightly hold the outer wall of the round thin-wall piece, and after the locking piece is locked, the two hoop circular arc plates can be fixed. And finally locking the nut on the threaded column to finish the center fixation of the round thin-wall part. Thereby realizing the complete fixation of the round thin-wall part.
